> In this paper, I will review some aspects of psychometric projects that

> statistical and scientific elements of that work. The intent is to seek
> to understand where psychometrics, as a discipline, has been and where
> it might be headed, in part at least, by considering one particular
> journey (my own). In contemplating this, I also look to psychometrics
> journals to see how psychometricians represent themselves to themselves,
> and in a complementary way, look to substantive journals to see how
> psychometrics is represented there (or perhaps, not represented, as the
> case may be). I present a series of questions in order to consider the
> issue of what are the appropriate foci of the psychometric discipline.
> As an example, I present one recent project at the end, where the roles
> of the psychometricians and the substantive researchers have had to
> become intertwined in order to make satisfactory progress. In the
> conclusion I discuss the consequences of such a view for the future of
> psychometrics.

> Abstract:
> We offer an introduction to the five papers that make up this special

> that face researchers analyzing fMRI data-the spatial, multilevel, and

> papers all provide analyses of data collected by a multi-site
> consortium, the Function Biomedical Informatics Research Network. Due to
> the sheer volume of data, univariate procedures are often applied, which
> leads to a multiple comparisons problem (since the data are necessarily
> multivariate). The papers in this section include interesting
> applications, such as a state-space model applied to these data, and
> conclude with a reflection on basic measurement problems in fMRI. All in
> all, they provide a good overview of the challenges that fMRI data
> present to the standard psychometric toolbox, but also to the

> Abstract:
> There is increasing use of functional imaging data to understand the
> macro-connectome of the human brain. Of particular interest is the
> structure and function of intrinsic networks (regions exhibiting
> temporally coherent activity both at rest and while a task is being
> performed), which account for a significant portion of the variance in
> functional MRI data. While networks are typically estimated based on the
> temporal similarity between regions (based on temporal correlation,
> clustering methods, or independent component analysis [ICA]), some
> recent work has suggested that these intrinsic networks can be extracted
> from the inter-subject covariation among highly distilled features, such
> as amplitude maps reflecting regions modulated by a task or even
> coordinates extracted from large meta analytic studies. In this paper
> our goal was to explicitly compare the networks obtained from a
> first-level ICA (ICA on the spatio-temporal functional magnetic
> resonance imaging (fMRI) data) to those from a second-level ICA (i.e.,
> ICA on computed features rather than on the first-level fMRI data).
> Convergent results from simulations, task-fMRI data, and rest-fMRI data
> show that the second-level analysis is slightly noisier than the
> first-level analysis but yields strikingly similar patterns of intrinsic
> networks (spatial correlations as high as 0.85 for task data and 0.65
> for rest data, well above the empirical null) and also preserves the
> relationship of these networks with other variables such as age (for
> example, default mode network regions tended to show decreased low
> frequency power for first-level analyses and decreased loading
> parameters for second-level analyses). In addition, the best-estimated
> second-level results are those which are the most strongly reflected in
> the input feature. In summary, the use of feature-based ICA appears to
> be a valid tool for extracting intrinsic networks. We believe it will
> become a useful and important approach in the study of the
> macro-connectome, particularly in the context of data fusion.

> Abstract:
> The neural correlates of working memory (WM) in schizophrenia (SZ) have
> been extensively studied using the multisite fMRI data acquired by the
> Functional Biomedical Informatics Research Network (fBIRN) consortium.
> Although univariate and multivariate analysis methods have been
> variously employed to localize brain responses under differing task
> conditions, important hypotheses regarding the representation of mental
> processes in the spatio-temporal patterns of neural recruitment and the
> differential organization of these mental processes in patients versus
> controls have not been addressed in this context. This paper uses a
> multivariate state-space model (SSM) to analyze the differential
> representation and organization of mental processes of controls and
> patients performing the Sternberg Item Recognition Paradigm (SIRP) WM
> task. The SSM is able to not only predict the mental state of the
> subject from the data, but also yield estimates of the spatial
> distribution and temporal ordering of neural activity, along with
> estimates of the hemodynamic response. The dynamical Bayesian modeling
> approach used in this study was able to find significant differences
> between the predictability and organization of the working memory
> processes of SZ patients versus healthy subjects. Prediction of some
> stimulus types from imaging data in the SZ group was significantly lower
> than controls, reflecting a greater level of
> disorganization/heterogeneity of their mental processes. Moreover, the
> changes in accuracy of predicting the mental state of the subject with
> respect to parametric modulations, such as memory load and task
> duration, may have important implications on the neurocognitive models
> for WM processes in both SZ and healthy adults. Additionally, the SSM
> was used to compare the spatio-temporal patterns of mental activity
> across subjects, in a holistic fashion and to derive a low-dimensional
> representation space for the SIRP task, in which subjects were found to
> cluster according to their diagnosis.

> the distribution G generating the abilities is a parameter of interest.
> It is not only shown that, after fixing a difficulty parameter and a
> guessing parameter at zero, the item parameters are identified, but also
> that under those restrictions the distribution G is not identified. It
> is finally shown that, after introducing two identification
> restrictions, either on the distribution G or on the item parameters,

> Abstract:
> The present work examined predicted relations among Life History
> strategies, Executive Functions, socially antagonistic attitudes,
> socially antagonistic behaviors, and general intelligence. Life History
> (LH) theory predicts that Executive Functions and socially antagonistic
> attitudes and behaviors underpin an interrelated and coherent set of
> behavioral strategies (LH strategies) designed to enhance reproductive
> success. Specifically, LH theory predicts a positive relation between
> Executive Functioning and LH strategies; a negative relation between
> socially antagonistic attitudes and behaviors and LH strategies; and
> that Executive Functions mediate relations among LH strategies and
> socially antagonistic attitudes and behaviors. Results from a Structural
> Equation Model (SEM), based on self-reported Life History strategies,
> Executive Functioning, socially antagonistic attitudes and behaviors,
> and general intelligence support these predictions. The structure of the
> model suggests that Executive Functions serve a mediating role in the
> relations between LH strategy and social deviance. (C) 2012 Elsevier

> Abstract:
> This research examined whether non-g residuals of the SAT and ACT
> subtests, obtained after removing g, predicted specific abilities. Non-g
> residuals of the verbal and math subtests of the SAT and ACT were
> correlated with academic (verbal and math) and non-academic abilities
> (speed and shop), both based on the Armed Services Vocational Aptitude
> Battery. Non-g residuals of the SAT and ACT math subtests were
> positively related to math ability and negatively to verbal ability,
> whereas the opposite pattern was found for the verbal subtests. Non-g
> residuals of both sets of subtests were weakly related to non-academic
> abilities. The results support an investment theory of skills and
> abilities: Investing in skills in one area (e.g., math) improves
> abilities in that area but lowers abilities in competing areas (e.g.,

Dear Kevin,
If you hear "executive function" and think of a successful CEO, think again! Every one of us uses executive functions daily as we think, process, and perform various tasks. Several executive skills fall under this "mental umbrella" — and each of us is stronger in some than in others.
Learning disabilities and weak executive function often go hand-in-hand. Learn more about executive function (and dysfunction) and get crucial tips in the following pieces:There's a lot of information and insight here, so put on your thinking cap (which, as you will learn, is as unique as you are).

IQ Scholar: Oliver Wilhelm
Another intelligence researcher (Oliver Wilhelm) I have been following for years but had failed to include in the IQ Scholar blogroll---until today. Excellent researcher. I highly recommend serious intelligence scholars follow his research.
Posted with Blogsy
IQ Scholar: Klaus Oberauer
I just added Dr. Klaus Oberauer to the IQs Scholar blogroll. I have been following his excellent research on working memory for years and somehow forgot to add him to this list. He should have been listed long ago. Oversight now corrected. I strongly recommend people follow his research.
