The motivated appeal to hypocrisy: the relation of motivational threats to message rejection.

Few studies have focused on the conditions in which individuals perceive hypocrisy in others. The current study introduces and tests the Motivated Appeal to Hypocrisy (MAtH) hypothesis. This hypothesis examines core social psychological motivational threats and asks (a) whether these are related to the accounts of individuals in charging others with hypocrisy, and (b) whether these perceptions of hypocrisy are associated with reductions in the persuasiveness of persons targeted as hypocrites.

The importance of cognitive diversity for sustaining the commons.

Cognitive abilities underpin the capacity of individuals to build models of their environment and make decisions about how to govern resources. Here, we test the functional intelligences proposition that functionally diverse cognitive abilities within a group are critical to govern common pool resources. We assess the effect of two cognitive abilities, social and general intelligence, on group performance on a resource harvesting and management game involving either a negative or a positive disturbance to the resource base.

The need to belong and its association with fully satisfying relationships: A tale of two measures.

The current research compares the Need to Belong Scale (NTBS; Leary et al., 2013) and the Antecedents subscale of the Sense of Belongingness Inventory (SOBI-A; Hagerty & Putusky, 1995) to determine whether they represent approach or neuroticism-driven avoidance orientations in the need to belong. This research also extends previous research on these constructs to examine direct and moderating associations involving the need to belong and the quantity and quality of personal close relationships.

Asymmetries in perceptions of self and others' hypocrisy: Rethinking the meaning and perception of the construct.

This article examines how people recall and describe instances of hypocrisy in their own and others' behaviour. N = 302 participants provided two written examples. The first example recalled a time when someone called the participant a hypocrite, while the other recalled an instance when the participant perceived someone else's behaviour as hypocritical.

Beliefs regarding stimulant medication effects among college students with a history of past or current usage.

Objective: To examine the beliefs of ADHD college students concerning stimulant medications and to apply the theory of planned behavior toward better understanding the factors instrumental in decisions regarding stimulant use.

Method: A cross-sectional, correlational design was used, and students completed a survey under controlled laboratory conditions. Participants were 193 students taking introductory psychology who self-reported receiving a diagnosis of attention deficit disorder or ADHD and a treatment history of using stimulant medications.

Processing speed mediates the development of general intelligence (g) in adolescence.

In the research reported here, we examined whether processing speed mediates the development of general intelligence (g) in adolescence. Using the Armed Services Vocational Aptitude Battery, a battery of 12 diverse cognitive tests, we assessed processing speed and g in a large sample of 13- to 17-year-olds obtained from the National Longitudinal Survey of Youth (N = 6,969). The direct effect of age on g was small compared with the total effect of age on g, which was almost fully mediated through speed.

SAT predicts GPA better for high ability subjects: Implications for Spearman's Law of Diminishing Returns.

This research examined the predictive validity of the SAT (formerly, the Scholastic Aptitude Test) for high and low ability groups. SAT scores and college GPAs were obtained from the 1997 National Longitudinal Survey of Youth. Subjects were classified as high or low ability by g factor scores from the Armed Services Vocational Aptitude Battery.

Cortical sulci and bipolar disorder.

The width of cortical sulci in bipolar patients (n=19) and healthy controls (n=35) was examined using a novel automated technique involving magnetic resonance imaging. All sulci were wider for bipolar patients than for healthy controls. Bipolar-control differences were largest for the superior and intermediate frontal sulci, smallest for the occipital and cingulate sulci, and intermediate in magnitude for the other sulci (intraparietal, inferior frontal, and central sulci).

Do boys with attention-deficit/hyperactivity disorder have positive illusory self-concepts?

One hundred ninety-five boys with attention-deficit/hyperactivity disorder (ADHD) were compared with 73 comparison boys (M = 9.83 years, SD = 1.30) on self-perceptions relative to a teacher-rated criterion.

Effects of methylphenidate and expectancy on children with ADHD: behavior, academic performance, and attributions in a summer treatment program and regular classroom settings.

Pharmacological and expectancy effects of 0.3 mg/kg methylphenidate on the behavior and attributions of boys with attention-deficit/hyperactivity disorder were evaluated. In a within-subject, balanced-placebo design, 136 boys received 4 medication-expectancy conditions.
