AI Brief: What does Grok say about Richard Snow’s aptitude trait complexes for learning?

 The following is a Grok AI generated summary when prompted (by Dr. Kevin McGrew) to explain Richard Snow’s aptitude complexes on March 7, 2026).

(Grok refers to a generative artificial intelligence developed by xAI, an Elon Musk company, as well as a foundational term in science fiction for deep understanding. Several editorial changes were made to insure accuracy, and select links added, by McGrew—to the Grok summary).

 


Richard E. Snow’s aptitude complexes (introduced in the 1980s–1990s, with key publications in 1987, 1992, and especially the 1996 chapter with Lyn Corno and Douglas Jackson) represent a major shift in how educational psychologists think about aptitudemoving far beyond the traditional narrow view of aptitude as “just cognitive ability” (e.g., IQ or a single test score).

 

Core Definition

Snow redefined aptitude as:

the degree of readiness to learn and to perform well in a particular situation or in a fixed domain.”

It is a predisposition or propensity—a latent quality that enables more advanced performance under specific conditions. Aptitudes are situational and domain-specific: what makes someone ready to succeed in math class may be different from what works in a history seminar or a hands-on lab.  


Aptitude Complexes (the key innovation)

Snow argued that single constructs (like “fluid reasoning” or “achievement motivation”) are insufficient. Instead, success in learning comes from aptitude complexes—dynamic constellations or critical combinations of variables that work together as a coordinated system.

These complexes draw from the classic “trilogy of the mind”:

•  Cognition — abilities and processes for analyzing, interpreting, and solving (e.g., reasoning, knowledge, strategies, cognitive style, CHC abilities).

•  Affect — emotions, anxiety, self-concept, emotion regulation, personality traits.

•  Conation — motivation, volition, goal-setting, effort, persistence, will (the “want to” and “stick with it” aspects).

An aptitude complex is not just a list of traits—it is how these elements assemble and coordinate in real time within a specific task and context. They are amalgams of cognitive, conative, and affective characteristics.

 

The Two Pathways That Build Aptitude Complexes

Snow (and later Corno et al., 2002) described aptitudes developing through two parallel, interacting pathways (sometimes called the commitment pathway and the performance/action pathway):

1.  Commitment Pathway (motivational/affective/volitional)

     •  Assembles motivational resources that energize effort.

     •  Affective and volitional processes modulate how the work proceeds (e.g., regulating anxiety, sustaining intention).

     •  Outcome: Propensity (how likely the person is to engage and persist).

2.  Performance (Action) Pathway (cognitive)

     •  Assembles and deploys cognitive resources (abilities, strategies, knowledge) to do the task.

     •  Outcome: Ability/accuracy in execution.

When the two pathways coordinate effectively in a given “problem space” (the task + the broader situation/context), successful performance occurs. Over repeated experiences, these coordinated processes coalesce into stable aptitude complexes. The learner’s perception of the situation’s constraints and affordances is crucial—aptitudes are dynamic and transactional (person ↔ environment). 

Aptitudes are both input (what the student brings to learning) and product (they develop and change through education).


Snow Academic Aptitude Model (SAAM)

Snow synthesized decades of research into a provisional taxonomy (called the Snow Academic Aptitude Model or SAAM in an unpublished working white paper [6-15-04; Increasing the Chance of No Child Being Left Behind: Beyond Cognitive and Achievement Abilities, by Kevin McGrew, David Johnson, Anna Casio, Jeffrey Evans]) which is now available for download here. It treats academic aptitudes as a “multivariate repertoire” of readiness for general and domain-specific learning. It explicitly includes affect (personality and social-emotional skills) and conative related skills and traits (e.g., achievement motivation, goal orientation, freedom from debilitating anxiety, positive self-concept, self-efficacy, interests) alongside cognitive abilities. The model emphasizes that “there is more to knowing about an individual’s propensity for academic learning than simply knowing their IQ scores!” 

 

Why This Mattered (and Still Matters)

Snow’s work grew out of his famous Aptitude-Treatment Interaction (ATI) research with Lee Cronbach. He showed that simple aptitude scores rarely predict learning outcomes well because real-world performance depends on these richer, situation-specific complexes.

This framework directly inspired later theories (including Kevin McGrew’s 2022 CAMML model, which updates Snow’s complexes with contemporary CHC cognitive theory, Big Five personality, and self-regulated learning mechanisms while retaining the commitment/action pathway structure).

In short, Snow’s aptitude complexes gave us a whole-person, dynamic, domain-specific way to understand why two students with the same IQ can have dramatically different learning outcomes: their aptitude complexes (the coordinated cognitive + affective + conative “package” or “amalgam”) fit the demands of the task and context differently.

Snow’s legacy is summarized in the 2002 book Remaking the Concept of Aptitude (Corno et al.), which remains the definitive extension of his ideas.

AI Brief: The trilogy-of-the-mind individual difference construct (cognitive, conative, affective) “band is getting back together” as CAMML

I am currently working to expand my skill set by incorporating AI tools. Although adapting to new technologies can be challenging, leveraging these resources offers significant benefits for professional growth.


This AI Brief was produced by requesting Google NotebookLM—recommended by Dr. Adam Lockwood—to generate a narrative summary of my 2022 PDF article describing the Cognitive-Affective-Motivation-Model of Learning (CAMML). While I found the first results promising, I made more edits to enhance its accuracy and informativeness. My next goal is to use AI to summarize multiple articles, find similarities and differences, and potentially create comparative tables (again following guidance graciously provided by Dr. Lockwood).


These incremental steps mark my transition toward utilizing AI to support one of my primary professional interests: producing informative blog and social media posts aimed at professionals such as school psychologists and special education teachers working with students who often are marginalized in educational contexts. The goal is to help bridge the gap between theory, technology, research, and practical application.

 

Feedback is encouraged and may be directed to iqmcgrew@gmail.com or via the social media platform (LinkedIn, Twitter/X, BlueSky) comment feature where this blog post was discovered. I’m hoping to add AI Briefs as a regular feature of IQs Corner Blog and associated social media platforms.

 

 

AI Brief: The trilogy-of-the-mind individual difference construct (cognitive, conative, affective) “band is getting back together” as CAMML

 

Dr. Kevin McGrew with assist from Google NotebookLM

 

The Cognitive-Affective-Motivation Model of Learning (CAMML; McGrew, 2002)[1] is a proposed theoretical framework designed to integrate contemporary motivational, affective, and cognitive constructs into a unified model for the practice of school psychology. The central thesis of the framework is that school psychologists must move beyond a narrow focus on intelligence (general intelligence or psychometric g in particular) to embrace an updated "trilogy-of-the-mind" model, which views intellectual functioning as the inseparable interaction of cognition, conation (motivation/volition), and affect.


Theoretical Foundations and the Rebirth of Conation

 

The CAMML framework is heavily rooted in the seminal work of Richard Snow, specifically his research on aptitude trait complexes. McGrew argues that the field of school psychology has historically neglected Snow’s broader definition of aptitude—which includes personality and motivational differences alongside cognitive abilities—and instead, has favored a restricted view of aptitude as synonymous with IQ or psychometric g.

 

CAMML seeks to resurrect conation (the proactive part of motivation connecting cognition and affect to behavior) as a core pillar of intellectual functioning. By "standing on the shoulders of giants" like Snow, Spearman, and Wechsler, the model asserts that cognitive processes cannot be understood in isolation from the "nonintellectual" (conative) factors that drive and direct them. For example, David Wechsler defined intelligence as "the aggregate or global capacity of the individual to act purposefully, to think rationally, and to deal effectively with his environment." While this is the core of Wechsler’s definition, he also strongly emphasized this capacity is influenced by non-intellective (conative) variables such as drive, persistence, interest, emotional states, and personality traits.

 

Structural Components of the CAMML Framework

 

The model organizes individual differences characteristics into three functional categories, which could be called the 3-D model.

 

      Affective “Dispositions”: These are distal-to-learning traits, primarily represented by the Big 5 personality traits (specifically Openness and Conscientiousness) and their associated social-emotional facets (e.g, curiosity, creativity, persistence, focus, determination). These personality traits act as dispositions that indirectly influence learning through more proximal mechanisms.

 

      Motivational "Drivers": Motivation is conceptualized as the initiation of behavior, formed by achievement orientations (e.g., goals, interests) and self-beliefs (e.g., self-efficacy, self-concept). These constructs are typically domain-specific (e.g., math) and work in synergistic "complexes" to energize a student's readiness to act.[2]

 

      Volitional "Directors": Volition, or self-regulated learning (SRL), represents the post-decisional phase of action. These are the mechanisms that direct, control, and regulate behavior toward goals once a commitment to learn has been made.

 

A more detailed list of the 3-D CAMML domain constructs and definitions is available here. See figure below for a visual representation of the major affective and conative MACM constructs (click on image to enlarge for easy viewing and reading).



 

The "Crossing the Rubicon" Investment Model

 

The functional heart of CAMML is the "Crossing the Rubicon" model, which illustrates the pathway from initial desire to engaged motivated learning. In this model:

 

  1. Pre-decisional Phase: Achievement orientations and self-beliefs drive or prepare the learner to start a wish—>want—> intention sequence, that eventually eventuates in motivated action.
  1. Commitment: When the learner "crosses the Rubicon," they are making a firm commitment to motivated action through cognitive engagement.
  1. Action Phase: Volitional (SRL) strategies steer the cyclical process via action results feedback while the learner invests cognitive abilities (such as those defined by CHC theory) to acquire knowledge.
  1. Outcomes: This personal investment of fluid cognitive processes (Cattell's general gf that subsumes broad Gf, Gv, Ga, Gwm, Gl, Gr, and Gs abilities) during learning results in the development of crystallized knowledge systems (Cattell’s general gc that subsumes broad Gc, Grw, Gq, and Gkn abilities).

Implications for School Psychology Practice

 

CAMML advocates for a paradigm shift in assessment and intervention. It suggests that school psychologists should transition from routine, comprehensive cognitive testing toward more time-efficient selective, referral-focused cognitive assessments combined with the assessment of key conative (non-cognitive) characteristics that contribute to learning aptitude complexes. This approach prioritizes identifying manipulable instructional levers, such as a student's motivational orientation (e.g., intrinsic motivation, interests, goal orientation), self-beliefs (e.g., locus of control, self-efficacy, growth or competence mindset), rather than relying exclusively on cognitive ability scores (especially full-scale IQ or g) that have proven hard to modify.

 

The framework provides a "whole-child" perspective to better address the nuances of individual differences, particularly as students move from the traditional “industrial” model of education (i.e., regularly scheduled, structured, in-class teacher-directed learning) to more of an “information-age” paradigm of education—a paradigm that requires a fuller expression of independent motivated self-regulated learning (SRL).

Let’s hear it for #conative (#noncognitive) variables in understanding learning—#CAMML #aptitude #traitcomplexes #cognitive #affective #motivation #schoolpsychology

 Variation in the intensity and consistency of attention during learning: The role of conative factors

Abstract

The present study examined whether conative factors (e.g., self-efficacy, self-set goal difficulty, and task-specific motivation) are reliable predictors of learning and memory abilities and whether any observed relationships could be explained by two related, yet distinct aspects of attention. Specifically, the present study examined whether the relationship between conative factors and overall learning performance is explained by attentional intensity (the amount of attention allocated to a task) and attentional consistency (the consistency with which attention is allocated to said task). In two studies (N’s > 160), participants completed a paired associate’s (PA) cued recall task while pupil diameter was simultaneously recorded to provide an index of the intensity of attention. Measures of working memory, general episodic long-term memory, task-specific motivation, and memory self-efficacy were also included. Study 2 adopted a similar procedure but embedded thought probes into the encoding phase of each list to provide an index of the consistency of attention. Study 2 also added measures of self-set goal difficulty and effective strategy use. Results suggested that all conative factors were related to intensity and consistency in challenging learning contexts. Furthermore, intensity, consistency, and the variance shared between self-efficacy and self-set goal difficulty (r = 0.86) each explained substantial unique variance in learning when controlling for the influence of other important predictors. Overall, results suggest conative factors are important for understanding individual differences in learning and memory abilities, and part of the reason why these factors are associated with improved learning outcomes is due to intensity and consistency.
Comment:  I’ve always believed that conative (non-cognitive) individual difference variables should receive just as much attention as cognitive variables in understanding learning.  In fact, in an invited article, I recently proposed the CAMML (cognitive-affective-motivation model of learning) “crossing the rubicon” model of learning that integrates conative (motivation and self-regulated learning), affective (Big 5 personality) and cognitive (CHC) variables in an overarching framework (building on Richard Snow’s concept of aptitude-trait complexes).  Click here to download or read the CAMML article.  Below are the two key figures for understanding the CAMML model.

The Motivation and Academic Competence (MACM) Commitment Pathway to Learning Model: Crossing the Rubicon to Learning Action

[2-24-13.  Since this original  blog post appeared, I have received requests for printed copies.  To meet this request I have published this post as the first MindHub (TM) Pub. This publication can be downloaded here.]

 

There is only one unequivocal law of human behavior—the law of individual differences.  People are more different than they are alike. Probably no environment elicits individual differences sooner in life than formal education.
 
When asked by teachers or parents to help understand why a particular student is not achieving adequately, school psychologists have traditionally reached for an intelligence battery.  Although understanding a student’s general, broad and specific cognitive abilities contributes important information for determining general expectations and the need for special instructional serves, at best, measures of cognitive abilities account for only approximately 40% to 50% of a student’s predicted achievement.  Much is still unexplained.  Furthermore, attempts at modifying intelligence, or identifying evidence-based cognitive-aptitude-achievement interactions (ATI's) that can be implemented at the level of individual students, have not yet provided the magical link between cognitive ability testing and evidence-based instructional or cognitive modifiability recommendations.  It is clear that school psychologists must go “beyond IQ” to help teachers, parents, and students themselves, to maximize student learning.
    
But…if not IQ…then what?  The more appropriate question is “what should be added to cognitive ability assessment information to help school psychologists facilitate the achievement of all learners?”  To provide some answers to this question this paper was developed with three primary goals.  First, a conceptual framework is presented to help school psychologists better understand the salient non-cognitive individual difference student variables to consider when engaging in learning-related assessments and instructional planning.  Second, the primary domains of the model are defined.  Finally, how the various domains work within a commitment pathway model to learning (crossing the active learning rubicon) is briefly presented.

Beyond IQ:  What Models of School Learning Have Told Us

A number of comprehensive models of school learning have been advanced to describe and explain the school learning process (see McGrew, Johnson, Cosio, & Evans, 2004).  Walberg's (1981) theory of educational productivity is one of the few empirically tested theories of school learning.  Walberg's model is based on an extensive review and integration of over 3,000 studies (DiPerna, Volpe & Stephen, 2002; Wang, Haertel, and Walberg, 1997).  Walberg et al. reported that the following key variables are important for understanding school learning—student ability and prior achievement, motivation, age or developmental level, quantity of instruction, quality of instruction, classroom climate, home environment, peer group, and exposure to mass media outside of school (Walberg, Fraser & Welch, 1986).  The first three variables (ability, motivation, and age) reflect student individual difference characteristics.  The fourth and fifth variables reflect characteristics of instruction  (quantity and quality), and the final four variables (classroom climate, home environment, peer group, and exposure to media) represent aspects of the psychological environment (DiPerna et al., 2002).  Clearly student characteristics are important for school learning, but they only comprise a portion of the complete learning equation.

The Walberg research group (see Wang, Haertel, & Walberg, 1993) also concluded that psychological, instructional, and home environment characteristics (proximal variables) had a more significant impact on achievement than variables such as state-, district-, or school-level policy and demographics (distal variables).  More important for practicing school psychologists was the conclusion that student characteristics (i.e., social, behavioral, motivational, affective, cognitive, metacognitive) were the set of proximal variables that had the most significant impact on learner outcomes (DiPerna et al., 2002).

Beyond IQ:  The Need for a Non-Cognitive Learner Characteristic Taxonomy

If school psychologists are to focus on the most learning-relevant student characteristics (beyond cognitive abilities), what individual difference student characteristic domains should receive priority?  Even a partial list of potentially important non-cognitive domains mentioned in the school psychology literature is staggering.  Social-emotional learning.  Motivation.  Self-efficacy.  Engagement.  Study and homework skills.  Resilience.  Executive functions.  Engaged learning time.  Self-regulated learning strategies.  Social skills.   Social and emotional intelligence.  What are the similarities and differences between these different constructs?  Does each construct consist of a single dimension or is there a complex model of subdomain characteristics within each construct domain?  Where is a school psychologist to start?   It my opinion that the answer first lies in outlining a working taxonomy of important non-cognitive learning-related student characteristics.

I am an admitted taxonomist.  As stated in the context of human cognitive abilities, Joel Schneider and I stated “A useful classification system shapes how we view complex phenomena by illuminating consequential distinctions and obscuring trivial differences. A misspecified classification system orients us toward the irrelevant and distracts us from taking productive action. Imagine if we had to use astrological classification systems for personnel selection, college admissions, jury selection, or clinical diagnosis. The scale of inefficiency, inaccuracy, and injustice that would ensue boggles the mind.  Classification is serious business(Schneider & McGrew, 2012, p. 99).
 
I believe that before defining and articulating instructional implications of important non-cognitive student characteristics, the broad domain(s) must first be circumscribed.  Furthermore, I believe that any working taxonomy must emerge from the extant empirical and theoretical literature, and not from the advocacy, policy, political arenas or narrow single trait programs of research.  Although a variety of models of school learning have been articulated, it is only recently that a model with sufficient breadth and depth, grounded in decades of educational and psychological research, has emerged with the potential to serve as a “bridging” mechanism between educational and psychological theory/research and educational practice.

Based on a large systematic program of educational research and research integration, Richard Snow and colleagues outlined a provisional and promising aptitude for learning taxonomy (Corno et al., 2002; Snow, Corno, & Jackson, 1996).  Richard Snow’s work unfortunately has flown under the radar screen of most of school psychology.  It is hoped that this brief paper rectifies this oversight by describing a Snow-inspired framework for understanding the most salient non-cognitive student characteristics that influence school learning.

A first attempt at outlining an adapted and updated Snow model, based on a comprehensive review and integration of approximately three decades of contemporary school learning research, was first described by McGrew et al. (2004).  This model was next revised as the Model of Academic Competence and Motivation (McGrew, 2007).   Figure 1 presents the  revision and update of the McGrew 2007 MACM model.

The Model of Academic Competence and Motivation (MACM):  A Brief Overview

 The MACM model includes the three broad domains of orientations towards self (motivations), volitional controls (cognitive strategies and styles), and orientations towards others (social ability). [1]   As illustrated in Figure 1, the current focus is on the motivational and volitional domains of conation.  The term conative, as well as volition, may partially explain why Snow and colleagues work has not been widely infused into education and school psychology.  Conative and volition are not commonly used terms in education or psychology and, frankly, would result in puzzled looks from teachers and parents if used to describe characteristics of a student.  However, they are important and have been part of a long standing “ancient trilogy of human mental functioning that consists of cognition, affection and conation” (Corno, 1996, p.14, italics added).  This current paper seeks to amplify the importance of conative abilities as articulated by many giants in the field of intelligence theory and testing.

PDF files that contain detailed definitions of the MACM characteristics and theoretical foundations can be found here and here.

Conative abilities have long been recognized as the important brides made-trait to cognition when attempting to explain intelligent performance or behavior.  The APA Dictionary of Psychology (Vandenbos, 2007) defines conation as “the proactive (as opposed to habitual) part of motivation that connects knowledge, affect, drives, desires, and instincts to behavior.  Along with COGNITION and affect, conation is one of the three traditionally identified components of mind” (p. 210; caps in original).  Charles Spearman, who all psychologists associate with the birth of the psychometric study of intelligence, recognized the importance of conative abilities.  Spearman (1927) stated that “the process of cognition cannot possibly be treated apart from those of conation and affection, seeing that all these are but inseparable aspects in the instincts and behavior of a single individual, who himself, as the very name implies, is essential indivisible” (p. 2).  Alfred Binet, who is considered the father of the modern day intelligence test, also recognized the importance of “non-intellectual” factors in cognitive or intellectual performance.  According to Corno et al. (2002):
  • Binet summed up his investigations in a famous description of intelligence: ‘the tendency to take and maintain a definite direction; the capacity to make adaptations for the purpose of attaining a desired end; and the power of auto-criticism’ (translation by Terman, 1916, p. 45).  All three of these phrases refer at least as much to conative processes and attitudes as to reasoning powers. Binet's concept of intelligence was much like Snow's concept of aptitudes (p. 5).
Sounding a similar chord, David Wechsler emphasized the importance of conative abilities, which he referred to as nonintellectual factors (e.g., persistence, curiosity, and motivation) (Zachary, 1990).  In Wechsler’s (1994) own words, “When our scales measure the nonintellectual as well as intellectual factors in intelligence, they will more nearly measure what in actual life corresponds to intelligent behavior” (Wechsler, 1944, p. 103).  More recently Richard Woodcock, first author of the WJ, WJ-R and WJ III, in his Cognitive Performance and Information Processing Models, includes the facilitator-inhibitor domain that includes both internal conative-like characteristics (e.g., health, attention and concentration, cognitive style), along with external variables (e.g., environmental distractions) that can “modify cognitive performance for better or for worse, often overriding the effects of strengths and weaknesses in the previously described cognitive abilities” (Woodcock, 1998, p. 146).

I humbly stand on the shoulders of Spearman, Binet, Wechsler, Woodcock and Snow  and recommend that school psychologists organize their thinking regarding essential student learning characteristics within a model of student competence and achievement that recognizes the importance of conative abilities.  To remove the terminology barrier to implementing this recommendation,  conative abilities have been renamed as motivations (orientations towards self) and cognitive strategies and styles (volitional controls; see Figure 1).  Being even more direct and simple, I have modified and extended the key question approach to understanding achievement motivation as presented by Wigfield and Eccles (2002).  The major domains represented in the MACM model (see Figure 1) can be reduced to five basic questions (borrowed and revised from Wigfield & Eccles, 2002) school psychologists should ask as they gather and integrate information regarding important non-cognitive school learning-related student information.

  • Does the student think they can do the task?  This question focuses on understanding the student’s self-beliefs regarding their perceived locus of control, academic self-efficacy, academic self-concept, and ability conception.
  • Does the student want to do the task and for what reasons?  When pondering this question, the goal is to understand the student’s motivational orientations such as degree of academic and intrinsic motivation, type of goal orientation, and the students’ goal setting abilities.  Additionally, understanding how a student values school learning and their global and situational academic domain-specific academic interests should be considered.
  • What does the student need to do to succeed on the task?  High motivation and positive self-beliefs are necessary but not sufficient conditions for succeeding in educational environments.  A bridge must link abilities, self-beliefs and motivation with action-oriented behavior.  The bridge is the presence of motivational controls or self-regulated learning strategies (e.g., study skills, cognitive and learning strategies, engagement) that allow individuals to manage efforts to accomplish their goal.
  • What are the student’s typical ways of responding to the task?  This question focuses on determining if a student has characteristic stable styles for approaching learning tasks, success or failure (e.g., self-worth protection; adaptive help-seeking) that either need to be enhanced or modified to insure increased positive achievement outcomes. 
  • How does the student need to behave towards others to succeed on the task?  Traditionally U.S. schools have valued student characteristics such as citizenship, conformity to social rules and norms, cooperation, and positive social behavior.  The student who does not know how (or who lacks the appropriate skills) to behave appropriately and responsibly is at increased risk for academic failure and the possibility of not developing a sense of belonging or relatedness. 

The MACM Framework and the Commitment Pathway to Learning Model:  Crossing the Rubicon to Learning Action

There is no consensus explanatory model outlining how the various constructs included in Figure 1 interact within the MACM model or with other important learner characteristics (e.g., cognitive abilities) to produce positive achievement outcomes.  In their introduction to the Handbook of Competence and Motivation, a seminal attempt to corral the major theories and research regarding motivation, self-regulatory processes and competence, Elliot and Dweck (2005) summarize this state of affairs when they stated, with regard to the weaknesses in the achievement motivation literature:
  • The literature lacks coherence and a clear set of structural parameters, and the literature is too narrowly focused and limited in scope.  In essence, what is commonly referred to as the “achievement motivation literature” represents a rather loose compendium of theoretical and empirical work focused on a colloquial understanding of the term “achievement” (p. 5). 
Further illustrating the impossible task of specifying a single consensus explanatory or causal MACM-achievement model is a recent series of reports from the Center on Education Policy (CEP)--Student Motivation:  School Reform's Missing Ingredient (Usher & Kober, 2012a).  No less than eight different expert or theoretical views of the dimensions of student motivation (which represents only the motivations component of the MACM model in Figure1) were the basis of the CEP’s series of six different policy briefs (Usher & Kober, 2012b).

Not only is the number of proposed explanatory models of achievement motivation a barrier to incorporating the MACM learner characteristics into school psychology practice, the complexity of some of the models is not practice friendly.  For example, the general expectancy-value model of achievement choices includes 11 separate model components (each with from 1 to 5 subcomponents) and over 12 different unidirectional or bidirectional arrows between components (Eccles, 2005).  A model focused just on evaluation anxiety during self-regulation includes 5 model components and 9 unidirectional arrows, while a proposed model of self-handicapping, which is just one self-protection style (i.e., a conative style in the MACM model—see Figure 1) is a figure with 11 different components and 13 different arrows (Rhodewalt & Vohs, 2005).  Finally, the MACM model includes two goal-related constructs (academic goal orientation and academic goal setting—see Motivational Orientations component in Figure 1), while a 1996 review of goal constructs in psychology listed 31 theories that have posited goal-like constructs and proposed a 6 domain, 24 subdomain taxonomy of human goals (Austin & Vancouver, 1996).
 
Against this backdrop, a simplified adaptation of Snow’s dynamic model of conation in the academic domain (Corno, 1993) is presented next.  It is assumed that the presentation of a simplified model is a first step towards helping school psychologists see the forrest-from-the-trees and thus, increases the chances of successful integration of the  MACM concepts in their assessment and instructional planning repertoire.  The MACM-based adaptation and extension of Snow’s model is presented in Figure 2.

In simple terms, a three-stage process is at the heart of understanding the learner’s commitment pathway to learning and achievement.  Learners first address the questions of “can I do this task?” and “do I want to do this task and why?”  These questions reflect the learner contemplating or deliberating over their beliefs regarding what they can do, what they want to do or are being asked to do, and what intentions they form (positive or negative) regarding how to proceed.  Cleary et al. (2010) describe this as the forethought stage, or those processes that occur before the student commits to the learning task.  For example, a student with a strong interest in science and a mastery goal orientation (i.e., wanting to learn for the sake of learning and mastering new skills) would likely decide to deploy strong and sustained engagement and effort on a science project.  Conversely, a learner with a long history of academic failure may not feel they are capable (low self-efficacy) and may want to avoid failure as their primary goal, which would result in a different decision—a different degree of commitment to a science project and possible deployment of self-protection conative style behaviors.  The act of committing to a course of action for a task has metaphorically being called “crossing the Rubicon” (Corno, 1993; Corno et al., 2002).   Once committed to implementing a plan, the success of the student attaining their goals is turned over to their self-regulated learning strategies (volitional controls)—carrying out the plans and intentions.  The student has moved into the domain addressed by the question “what do I need to do to succeed on the task?

Of course, this is on overly simple explanation of an obvious non-linear process where the results of plan implementation and self-regulation may require moving back to the contemplation and planning stage if the initials goals require modification (e.g., a student sets an unrealistic goal to perform perfectly on a math project).  Multiple recursive and dynamic iterations occur across the commitment to action pivot point (the Rubicon; see circle of arrows in Figure 1), with motivations modifying cognitive control and regulation strategies, and cognitive strategy feedback requiring goal adjustment and changes in plans, is often required.


Summary Comments

It is hoped that this brief description of the MACM model and the MACM Commitment to Learning Pathway Model (Crossing the Rubicon to Learning Action)stimulates thought, research, and further development.  Updates to this model will be posted at this blog and will typically be accessible by clicking on the MACM and Beyond IQ blog labels on the blog roll.

[1] A complete description and discussion of these three primary MACM domains is not possible here. The interested reader should review Corno et al. (2002), and McGrew et al. (2004) and McGrew (2007).  It is important to note that the MACM model is only a partial taxonomy of relevant school-related individual difference characteristics.  The model presented here only lists general categories under the two areas of Social Ability and does not include physical and psychomotor competences, affective or social-emotional characteristics, cognitive abilities, and overarching constructs such as personality, which Corno et al. (2002) include in the more comprehensive big picture taxonomy of aptitude related constructs.  The literature on social intelligence, social cognition, and social skills requires treatment in separate chapters or books.  Social ability is included in the MACM model to reflect an awareness of the importance of social ability and behavior constructs when discussing important non-cognitive characteristics important for school success.
