Intelligence and the brain: A model-based approach Rogier A. Kievit, Hilko van Rooijen, Jelte M. Wicherts, Lourens J. Waldorp, Kees-Jan Kan, H. Steven Scholte, and Denny Borsboom Various biological correlates of general intelligence (g) have been reported. Despite this, however, the relationship between neurological measurements and g is not fully clear. We use structural equation […]

STUDY ALERT: Sex Differences in the Brain: The Not So Inconvenient Truth
Sex Differences in the Brain: The Not So Inconvenient Truth Margaret M. McCarthy, Arthur P. Arnold, Gregory F. Ball, Jeffrey D. Blaustein, and Geert. J. De Vries The arguments for studying sex differences in the brain are as follows. (1) There is compelling evidence of pervasive and robust differences between males and females in both […]
STUDY ALERT: Predicting Preferences for Sex Acts: Which Traits Matter Most, and Why?
Predicting Preferences for Sex Acts: Which Traits Matter Most, and Why? Ashley Peterson, Glenn Geher, and Scott Barry Kaufman Several dispositional traits have been examined in mating contexts by evolutionary psychologists. Such traits include life history strategy, sociosexuality, and the Big Five. Recently, scholars have examined the validity and predictive utility of mating intelligence, a […]
STUDY ALERT: Openness, Fluid Intelligence, and Crystallized Intelligence: Toward an Integrative Model
Openness, Fluid Intelligence, and Crystallized Intelligence: Toward an Integrative Model Matthias Ziegler, Erik Danay, Moritz Heene, Jens Asendorpf, Markus Bühner Many studies are concerned with the bivariate relationships between Openness, fluid intelligence (Gf), and crystallized intelligence (Gc). Results suggest an influence of Gf and Openness on Gc. However, the overlap between Gf and Openness is […]
STUDY ALERT: Assessing Individual Differences in Commitment to Beliefs
Assessing Individual Differences in the Degree to Which People are Committed to Following Their Beliefs Matthew A. Maxwell-Smith, Victoria M. Esses The authors developed a new dispositional measure of Commitment to Beliefs (CTB)— the degree to which people feel it is important to follow their value-expressive beliefs— across three phases of research. In Phases 1 […]
STUDY ALERT: Publish (your data) or (let the data) perish! Why not publish your data too?
Publish (your data) or (let the data) perish! Why not publish your data too? Jelte M. Wicherts, Marjan Bakker The authors argue that upon publication of a paper, the data should be made available through online archives or repositories. Reasons for not sharing data are discussed and contrasted with advantages of sharing, which include abiding […]
STUDY ALERT: The variable nature of cognitive control: a dual mechanisms framework
The variable nature of cognitive control: a dual mechanisms framework Todd S. Braver A core component of cognitive control – the ability to regulate thoughts and actions in accordance with internally represented behavioral goals – might be its intrinsic variability. In this article, I describe the dual mechanisms of control (DMC) framework, which postulates that […]
STUDY ALERT: Are cognitive g and academic achievement g one and the same g?
Are cognitive g and academic achievement g one and the same g? An exploration on the Woodcock–Johnson and Kaufman tests Scott Barry Kaufman, Matthew R. Reynolds, Xin Liu, Alan S. Kaufman, Kevin S. McGrew We examined the degree to which the conventional notion of g associated with IQ tests and general cognitive ability tests (COG-g) […]
STUDY ALERT: Lower Cognitive Ability Predicts Greater Prejudice Through Right-Wing Ideology and Low Intergroup Contact
Bright Minds and Dark Attitudes: Lower Cognitive Ability Predicts Greater Prejudice Through Right-Wing Ideology and Low Intergroup Contact Gordon Hodson and Michael A. Busseri Abstract Despite their important implications for interpersonal behaviors and relations, cognitive abilities have been largely ignored as explanations of prejudice. We proposed and tested mediation models in which lower cognitive ability […]
STUDY ALERT: I like who you like, but only if I like you: Female character affects mate-choice copying
I like who you like, but only if I like you: Female character affects mate-choice copying Simon Chu Mate-choice copying is shown when women imitate the mate-choice preferences of other women.
STUDY ALERT: The Mere Anticipation of an Interaction with a Woman Can Impair Men’s Cognitive Performance
The Mere Anticipation of an Interaction with a Woman Can Impair Men’s Cognitive Performance Sanne Nauts • Martin Metzmacher • Thijs Verwijmeren • Vera Rommeswinkel • Johan C. Karremans Abstract Recent research suggests that heterosexual men’s (but not heterosexual women’s) cognitive performance is impaired after an interaction with someone of the opposite sex (Karremans et […]
STUDY ALERT: The Association between Resting Functional Connectivity and Creativity
Title: The Association between Resting Functional Connectivity and Creativity Authors: Hikaru Takeuchi, Yasuyuki Taki, Hiroshi Hashizume, Yuko Sassa, Tomomi Nagase, Rui Nouchi and Ryuta Kawashima Abstract The analysis of functional connectivity at rest (rFC) enables us to know how brain regions within and between networks interact. In this study, we used resting-state functional magnetic resonance […]
