Physical health, positive and negative affect, and personality: A longitudinal analysis

This study used structural equation modeling to examine longitudinal relations among physical health, personality and mood in a sample of 360 college students. Research focused on the longitudinal associations among physical health and mood and their systematic relations with the Big Five personality dimensions of Extraversion and Neuroticism. Longitudinal analyses over successive 1-month intervals revealed lagged reciprocal effects between physical health and negative affect. After controlling for the effect of negative affect, physical health influenced subsequent positive affect, but positive affect did not influence subsequent physical health. Implications of these findings for subsequent research on health, personality, and emotions are discussed.     

How general is the “General Factor of Personality”? Evidence from the Texas Adoption Project

Using data from samples of 300 and 220 adoptive families from the Texas Adoption Project, aspects of generality of a “General Factor of Personality” (GFP) were examined: across different personality inventories, across different levels of analysis (items, scales) within an inventory, across self- and others’ judgments, and across sexes, ages, and generations. Considerable, though not complete, generality was found. The average correlation between GFPs from items and scales of a given inventory was .90; between GFPs from the scales of different inventories was .48. Also examined were the heritability of a GFP, its degree of correlation with a general cognitive factor, and its ability to predict real-life criteria such as educational level, marital stability, and substance abuse.     

Decomposing animacy reversals between agents and experiencers: An ERP study

The present study aimed to refine current hypotheses regarding thematic reversal anomalies, which have been found to elicit either N400 or - more frequently - “semantic-P600” (sP600) effects. Our goal was to investigate whether distinct ERP profiles reflect aspectual-thematic differences between Agent-Subject Verbs (ASVs; e.g., ‘to eat’) and Experiencer-Subject Verbs (ESVs; e.g., ‘to love’) in English. Inanimate subject noun phrases created reversal anomalies on both ASV and ESV. Animacy-based prominence effects and semantic association were controlled to minimize their contribution to any ERP effects. An N400 was elicited by the target verb in the ESV but not the ASV anomalies, supporting the hypothesis of a distinctive aspectual-thematic structure between ESV and ASV. Moreover, the N400 finding for English ESV shows that, in contrast to previous claims, the presence versus absence of N400s for this kind of anomaly cannot be exclusively explained in terms of typological differences across languages.     

The fate of redundant cues during blocking and a simple discrimination

In each of three experiments animals received blocking, A+ AX+, in which food was always presented after one stimulus, A, that was occasionally accompanied by another stimulus, X. They also received a simple discrimination, AX+ BX-, in which the presence and absence of food was signaled by two compounds that contained one unique cue, A or B, and one common cue, X. In each of these designs, X can be said to be redundant relative to A as a signal for food. Test trials at the end of training revealed that responding during X was stronger after blocking than after the simple discrimination. These results contradict predictions from theories of learning that assume changes in associative strength of a stimulus are determined by a global error term based on the outcome predicted by all the stimuli that are present for a conditioning trial. The results are interpreted, instead, by assuming either that animals store a memory of every trial to which they have been exposed, or that learning is governed by an error term based on the significance of individual stimuli.     

The Relationship between Temperamental Negative Affect,Effortful Control,and Sensory Regulation: A New Look

Temperamental negative affectivity (NA) and effortful control (EC) have long been of interest to psychologists, but sensory regulation (SR) has received less attention. Using confirmatory factor analysis, the present study reexamined the Rothbart model of EC and NA using the Children's Behavior Questionnaire (CBQ; M.K. Rothbart, S.A. Ahadi, K.L. Hershy, & P. Fisher, 2001), along with alternative models of EC, NA, and SR using the CBQ and Short Sensory Profile. The results failed to replicate the Rothbart model of EC and NA, which includes SR within the EC and NA factors. A good fit was found for a three‐factor model (EC, NA, and SR) that was replicated in a holdout sample. A three‐factor model also showed a good fit when EC, NA, and SR items similar to symptoms of behavior problems were eliminated.     

What Is and Is Not Ethnocentrism? A Conceptual Analysis and Political Implications

Conceptual analysis has not been systematically implemented in psychology, and many concepts have often been defined in different and contradictory ways. This article focuses on a conceptual clarification of ethnocentrism. It points out the conceptual confusion surrounding the term, reviews numerous definitions and operationalizations, and attempts to clarify it. Ethnocentrism is reconceptualized as a strong sense of ethnic group self‐centeredness, which involves intergroup expressions of ethnic group preference, superiority, purity, and exploitativeness, and intragroup expressions of ethnic group cohesion and devotion. It is conceptually and empirically distinguished from other concepts, such as outgroup negativity and mere ingroup positivity. The article presents a theoretical framework and related empirical analyses supporting the usefulness of reconceptualized ethnocentrism. It also details important and unique implications of reconceptualized ethnocentrism for political phenomena. It is expected that reliance on the clarified reconceptualization should enable researchers to systematically study ethnocentrism, its origins, and consequences.     

A behavioral test of Horney’s linkage between authenticity and aggression: People living authentically are less-likely to respond aggressively in unfair situations

This study links Horney’s account of human growth and neurosis to authenticity by examining aggressive responses on the point subtraction aggressive paradigm, providing the first empirical test of whether authenticity can predict objective behavior. Data from undergraduate, postgraduate, and mature students demonstrate that when controlling for age, gender, trait-anger, agreeableness, and functional dimensions of coping, individuals who measure high on authentic-living respond less aggressively to attacks and counter-attacks in unfair situations. Authentic-living uniquely accounted for 14.2% of variance in aggressive-responses (r = −.37). The findings suggest that inauthenticity is a strong predictor of aggressive behavior, and therefore increasing levels of authenticity in counseling practice may reduce maladaptive levels of anger. We suggest future exploration between authenticity and models of emotional regulation will unearth the cause and effects of aggression within inauthentic individuals.     

Lower extremity strength and hopping and jumping ground reaction forces in children with neurofibromatosis type 1

The purpose of this study was to (1) extend the research findings of decreased muscular force production in grip strength to the lower extremity strength of children with NF1 and (2) to determine if there was a relationship between isometric strength and functional activities in children with NF1. Force production was assessed using a hand held dynamometer (HHD) and a functional task (hopping and jumping) on a force plate. Data from twenty-six children with NF1 were compared to data from 48 typically developing children of similar sex, weight and height. Children with NF1 demonstrated statistically significant lower force production with HHD (p<0.01) during hip extension, but similar force production for knee extension and ankle plantar flexion compared to the control group. A relationship existed between the ground reaction forces at take-off from both hopping and jumping and the force generated from knee extensor strength in the NF1 group. The addition of a functional task to hand held dynamometry is useful for determining a relationship between common clinical measures and functional activities.     

Faking on self-report emotional intelligence and personality tests: Effects of faking opportunity, cognitive ability, and job type

We assessed the combined effects of cognitive ability, opportunity to fake, and trait job-relevance on faking self-report emotional intelligence and personality tests by having 150 undergraduates complete such tests honestly and then so as to appear ideal for one of three jobs: nurse practitioner, marketing manager, and computer programmer. Faking, as expected, was greater (a) in higher-g participants, (b) in those scoring lower under honest conditions (with greater opportunity to fake), and (c) on job-relevant traits. Predicted interactions accounted for additional unique variance in faking. Combining all three factors yielded a “perfect storm” standardized difference of around 2, more than double the overall .83 estimate. Implications for the study of faking are discussed.
