Research Byte: A closer look at who "chokes under pressure" - importance of attentional control (AC)

Volume 5, Issue 4, December 2016, Pages 470–477
Working Memory in the Wild: Applied Research in Working Memory

A Closer Look at Who “Chokes Under Pressure”



Highlights

High pressure settings compromise working memory and decrease cognitive performance.
Those with higher working memory show greatest pressure-induced cognitive deficits.
Attentional control alters relation of working memory to performance under pressure.

Previous research has shown that the higher one's working memory capacity, the more likely his/her performance is to be negatively impacted by performance pressure. In the current research we examined potential explanations for this finding by assessing the relation between pressure-induced performance deficits (i.e. “choking under pressure”) in math-based problem solving and individual differences in both working memory (as assessed via complex span tasks) and attentional control (as assessed via two measures from an Eriksen Flanker task). We find higher working memory only relates to “choking under pressure” when individuals were low in attentional control. These results further elucidate the mechanism by which high-pressure scenarios can lead to errors in performance and carry implications for developing effective intervention strategies to prevent poor performance in high-stakes situations.

Research Byte: What paint can tell us: A fractal analysis of neurological changes in seven artists. via BrowZine

This is WAY cool. A promising method that, IMHO, might be applied to routine required repeated drawings in the elderly during regular physical exams. Also, would it be possible to develop fractal-based diagnostic norms from geometric drawings from standardize psychological drawing tests used in clinical practice? That is, fractal analyze all norm based drawings from a test, develop what is "normative" by age, and then flag drawings of clients that are divergent from typical? Need to file this for interesting possible new test development methods.

Remembering the "individual" in individual differences research: A quote to note

I just ran across this statement in a recent article (see below). It served as a reminder of something I have always preached, but from-time-to-time, tend to forget as I analyze cognitive ability test data, post research articles, or suggest hypotheses regarding test score differences---be it here at this blog, in a journal article, book, book chapter, or professional presentation. The point being that we must remain vigilant in remembering the "individual" in individual differences research.

The privileged unit of analysis in psychology is the individual (Nesselroade, Gerstorf, Hardy, & Ram, 2007). Nevertheless, many data-analytic approaches coarsely aggregate data and tacitly assume group-average models to hold and to be interpreted in lieu of more fine-grained and, ultimately, person-specific models. For example, when a group of persons show an average increase of performance in a learning task, this does not mean that all persons follow a pattern of change similar to this average. In fact, none of the persons may be well represented by the average trend. In a similar vein, Tucker (1966) argued that the consideration of differences instead of averages will allow us to gain more information about the nature of basic functions underlying behavior. Ever since, researchers have been questioning coarse aggregation of data across persons (e.g., Lamiell, 1981; Nesselroade & Molenaar, 1999) as the estimates of averaged effects may not be representative of any single individual. In fact, strong inference about intra-individual variation from interindividual variation is only possible under the ergodic assumption (Molenaar, 2004), which assumes that the group model represents each individual's dynamics (homogeneity) and that those dynamics have constant characteristics in time (stationarity). In the same vein, Simpson (1951) pointed out that a statistical relationship observed in a population could be reversed within subgroups that form the population. For instance, “It may be universally true that drinking coffee increases one's level of neuroticism; then it may still be the case that people who drink more coffee are less neurotic” (Borsboom, Kievit, Cervone, & Hood, 2009, p. 72). Simpson's paradox may arise whenever inferences are drawn across different explanatory levels, for example, from populations to the individual, or from cross-sectional data to intraindividual change over time (see Kievit, Frankenhuis, Waldorp, & Borsboom, 2013, for further illustrations). Hence, there still is a need for focusing on individuals or subgroups of individuals to more accurately model individual process idiosyncrasies and similarities across persons. Particularly, in light of large-scale empirical data sets, aggregation is more likely to lead to models with low informative value about individual underlying processes as it is often difficult to expand prior hypotheses to account for the large number of potential explanatory variables.

Detterman on the importance of human intelligence

In a recent article by Robert Colom (2016) in the Spanish Journal of Psychology, I was reminded of an important quote by one of the leaders in Intelligence over the past 50 years.....Dr. Doug Detterman

In the farewell editorial note published by D. K. Detterman after being editor of the journal ‘Intelligence' for four decades he wrote: “from very early, I was convinced that intelligence was the most important thing of all to understand, more important than the origin of the universe, more important than climate change, more impor-tant than curing cancer, more important than anything else. That is because human intelligence is our major adaptive function and only by optimizing it will we be able to save ourselves and other living things from ultimate destruction. It is as simple as that”.

Big data in psychology: Special issue of Psychological Methods

I just learned of this special issue in Psychological Methods.  I am looking forward to reading many of the articles as the idea of "big data" analysis in psychology is important.  I am particularly looking forward to reading the article co-authored by Jack McArdle on SEM trees.  I am not sure I will understand it, but I know Jack does tremendous work.  He was the first person to introduce me to SEM methods many years ago (during the WJ-R project; he taught me SEM, very gently, with a program called COSAN..and then I graduated to LISREL), and he was an awesome teacher---he could make complex stat methods conceptually clear.  I also then learned of decision-tree methods (CART, MAR) from Jack, and believe they should be used more in psychological research.  This PM issue should be well received by the quantoid readers of this blog.

Human intelligence research four-levels of explanation: Connecting the dots - an Oldie-But-Goodie (OBG) post

Click on image to enlarge.

Research that falls under the breadth of the topic of human intelligence is extensive.

For decades I have attempted to keep abreast with intelligence-related research, particularly research that would help with the development, analysis, and interpretation of applied intelligence tests.   I frequently struggled with integrating research that focused on brain-behavior relations or networks, neural efficiency, etc.  I then rediscovered a simple three-level categorization of intelligence research by Earl Hunt.  I modified it into a four-level model, and the model is represented in the figure above.

In this "intelligent" testing series, primary emphasis will be on harnessing information from the top "psychometric level" of research to aid in test interpretation.  However, given the increased impact of cognitive neuropsychological research on test development, often one must turn to level 2 (information processing) to understand how to interpret specific tests.

This series will draw primarily from the first two levels, although there may be times were I import knowledge from the two brain-related levels.

To better understand this framework, and put the forthcoming information in this series in proper perspective, I would urge you to view the "connecting the dots" video PPT that I previously posted at this blog.

Here it is.  The next post will start into the psychometric level information that serves as the primary foundation of "intelligent" intelligence testing.
