Is running away right? The behavioral activation-behavioral inhibition model of anterior asymmetry.

The measurement of anterior electroencephalograph (EEG) asymmetries has become an important standard paradigm for the investigation of affective states and traits. Findings in this area are typically interpreted within the motivational direction model, which suggests a lateralization of approach and withdrawal motivational systems to the left and right anterior region, respectively. However, efforts to compare this widely adopted model with an alternative account-which relates the left anterior region to behavioral activation independent of the direction of behavior (approach or withdrawal) and the right anterior region to goal conflict-induced behavioral inhibition-are rare and inconclusive. Therefore, the authors measured the EEG in a sample of 93 young men during emotional imagery designed to provide a critical test between the 2 models. The results (e.g., a correlation between left anterior activation and withdrawal motivation) favor the alternative model on the basis of the concepts of behavioral activation and behavioral inhibition. In addition, the present study also supports an association of right parietal activation with physiological arousal and the conceptualization of parietal EEG asymmetry as a mediator of emotion-related physiological arousal.

Self–other agreement in job performance ratings: A meta-analytic test of a process model.

This meta-analysis explores agreement in self- and supervisory ratings of job performance (k = 128 independent samples). It suggests a 3-stage model of the rating process and reviews the empirical evidence for the relevance of each of these 3 stages to an understanding of agreement in ratings. The proposed 3-stage model serves as the guiding rationale for the examination of an extensive set of variables that moderate rater agreement. Results are reported for 2 indicators of rater agreement (correlational and mean-level agreement). Self-supervisor ratings yielded an overall correlation of .22 (ρ = .34; k = 115; n = 37,752). Position characteristics and the use of nonjudgmental performance indicators were the main moderators. Leniency in self-ratings is indicated by higher mean levels of self-ratings compared with supervisory ratings. Within Western samples, performance self-ratings showed leniency (d = 0.32, Δ = .49; k = 89; n = 35,417) dependent on contextual features, scale format, and scale content.

The contributions of phonological awareness and letter-name knowledge to letter-sound acquisition—a cross-classified multilevel model approach.

In the present study, we investigated critical factors in letter-sound acquisition (i.e., letter-name knowledge and phonological awareness) with data from 653 English-speaking kindergartners in the beginning of the year. We examined (a) the contribution of phonological awareness to facilitating letter-sound acquisition from letter names and (b) the probabilities of letter-sound acquisition as a function of letter characteristics (i.e., consonant–vowel letters, vowel–consonant letters, letters with no sound cues, and vowel letters). The results show that letter-name knowledge had a large impact on letter-sound acquisition. Phonological awareness had a larger effect on letter-sound knowledge when letter names were known than when letter names were unknown. Furthermore, students were more likely to know the sounds of consonant–vowel letters (e.g., b and d) than vowel–consonant letters (e.g., l and m) and letters with no sound cues (e.g., h and y) when the letter name was known and phonological awareness was accounted for. Sounds were least likely to be known for letters with no sound cues, but reliable differences from other groups of letters depended on students' levels of phonological awareness and letter-name knowledge.

Research notes: The curious case of Catharine Cox (Miles): The 1926 dissertation and her Miles–Wolfe (1936) follow-up.

This article focuses on questions brought about by a volume written by Lewis M. Terman that was based on a doctoral dissertation that Catherine Cox conducted under Terman’s supervision. The five-volume series Genetic Studies of Genius reports a longitudinal study of more than 1,500 boys and girls who had scored exceptionally high on the new Stanford–Binet Intelligence Scale.

Do you two know each other? Transitivity, homophily, and the need for (network) closure.

The authors investigate whether need for closure affects how people seek order in judging social relations. In Study 1, the authors find that people who have a high need for closure (NFC) were more likely to assume their social contacts were connected to each other (i.e., transitivity) when this was not the case. In Studies 2 and 3, the authors examine another form of order in network relations—racial homophily—and find that high-NFC participants were more inclined to believe that 2 individuals from the same racial category (e.g., African American) were friends than two racially dissimilar individuals. Furthermore, high-NFC individuals were more likely to make errors when judging a racially mixed group of people; specifically, they recalled more racial homophily (racially similar people sitting closer together) than had actually appeared.

Trajectories of perceived support in mother–adolescent relationships: The poor (quality) get poorer.

The authors examined decreases across the early adolescent years in child reports of perceived support from mothers to determine whether the rate of decline differed as a function of the initial amount of perceived negativity in the mother–child relationship. Participants included a diverse sample of 197 girls and 116 boys who were in the 1st year of middle school (6th grade, ages 11 to 13 years) at the beginning of the study. Separate growth curve models revealed associations between the rate of change in child-reported perceived support and the initial level of both child-reported perceived negativity and mother-reported perceived negativity. Over-time declines in child-reported perceived support were larger for adolescents whose initial levels of perceived negativity were greater. The findings are consistent with the claim that mothers and children with the worst relationships at the outset of adolescence experience the greatest deterioration in relations across the early adolescent years.

What we think we do (to each other): How personality can bias behavior schemas through the projection of if–then profiles.

People's knowledge about others includes not only person schemas about the typical traits of others but also behavior schemas about the likely interpersonal consequences of different behaviors. In this article, it is argued that perceiver effects can be interactive at the level of behavior schemas. A person's own personality configuration of if–then responses in social interactions (Mischel & Shoda, 1995) may contribute to that person's beliefs about the meaning and impact of relational behaviors more generally. In consequence, people who experience strong (or weak) responses to behaviors that vary along a particular trait dimension, such as warmth–coldness, may expect others to experience similarly strong (or weak) responses to those same kinds of behaviors. In 3 studies, people who were high in trait communion expected others to respond more strongly to behaviors that varied in warmth–coldness than did people who were low in trait communion, and people who were low in trait agency expected others to respond more strongly to behaviors that varied in assertiveness–unassertiveness than did people who were high in trait agency. Studies 2 and 3 provided evidence that participants' behavior schemas were based on assumptions derived from their own if–then personality profiles.

Exemplar representation without generalization? Comment on Smith and Minda's (2000) "Thirty categorization results in search of a model."

J. D. Smith and J. P. Minda (see record 1999-15928-001) conducted a meta-analysis of 30 data sets reported in the classification literature that involved use of the "5–4" category structure introduced by D. L. Medin and M. M. Schaffer (1978). The meta-analysis was aimed at investigating exemplar and elaborated prototype models of categorization. In this commentary, the author argues that the meta-analysis is misleading because it includes many data sets from experimental designs that are inappropriate for distinguishing the models. Often, the designs involved manipulations in which the actual 5–4 structure was not, in reality, tested, voiding the predictions of the models. The commentary also clarifies various aspects of the workings of the exemplar-based context model. Finally, concerns are raised that the all-or-none exemplar processes that form part of Smith and Minda's (see record 1999-15928-001) elaborated prototype models are implausible and lacking in generality.

When do the stigmatized stigmatize? The ironic effects of being accountable to (perceived) majority group prejudice-expression norms.

How do frequently stigmatized individuals feel about and respond to members of other potentially stigmatizable groups? Four studies demonstrated that perceptions of majority group norms regarding prejudice expression can shape how minority individuals respond to minority individuals from other groups. Study 1 revealed that Black and White men and women have somewhat different perceptions of Whites' norms regarding prejudice expression. Study 2 manipulated whether evaluations of Native American job candidates were to remain private or to be made public to unfamiliar Whites upon whom the evaluators were dependent: Black men used a strategy of publicly (but not privately) denigrating the minority target to conform to presumed prejudice-expression norms. Study 3, in which the authors explicitly manipulated prejudice-expression norms, and Study 4, in which they manipulated audience race, further supported the role of such norms in eliciting public discrimination against minority group members by other minority group members. The desire to avoid being targeted for discrimination, in conjunction with the perception that the majority endorses discrimination, appears to increase the likelihood that the often-stigmatized will stigmatize others.

The impact of the Workshop Activity for Gender Equity Simulation in the Academy (WAGES–Academic) in demonstrating cumulative effects of gender bias.

We report experimental evaluation of the Workshop Activity for Gender Equity Simulation in the Academy (WAGES–Academic), a brief, experiential simulation of the cumulative effects of unconscious bias in the academic workplace. We predicted that participants who played WAGES–Academic would demonstrate significantly increased knowledge and retention of gender equity issues in the academic workplace compared with participants in a control condition. Baseline information on general knowledge of workplace gender equity issues was obtained from 1,254 undergraduates. In the second phase, 144 were randomly assigned to complete either WAGES–Academic or a control task, and the immediate effects of the activities were measured. Participants were contacted 7–11 days later to complete an online measure of knowledge retention. Compared with a control condition, WAGES–Academic increased knowledge and retention. This effect occurred irrespective of prior level of sexist beliefs, participant gender, or whether the participant had been on the advantaged or disadvantaged team. Potential use and testing of WAGES–Academic with university faculty and administrators are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Are birds smarter than mathematicians? Pigeons (Columba livia) perform optimally on a version of the Monty Hall Dilemma.

The “Monty Hall Dilemma” (MHD) is a well known probability puzzle in which a player tries to guess which of three doors conceals a desirable prize. After an initial choice is made, one of the remaining doors is opened, revealing no prize. The player is then given the option of staying with their initial guess or switching to the other unopened door. Most people opt to stay with their initial guess, despite the fact that switching doubles the probability of winning. A series of experiments investigated whether pigeons (Columba livia), like most humans, would fail to maximize their expected winnings in a version of the MHD. Birds completed multiple trials of a standard MHD, with the three response keys in an operant chamber serving as the three doors and access to mixed grain as the prize. Across experiments, the probability of gaining reinforcement for switching and staying was manipulated, and birds adjusted their probability of switching and staying to approximate the optimal strategy. Replication of the procedure with human participants showed that humans failed to adopt optimal strategies, even with extensive training.

Utility of the MMPI–2-RF (Restructured Form) validity scales in detecting malingering in a criminal forensic setting: A known-groups design.

The current study examined the utility of the recently released Minnesota Multiphasic Personality Inventory–2 Restructured Form (MMPI–2-RF; Ben-Porath & Tellegen, 2008) validity scales to detect feigned psychopathology in a criminal forensic setting. We used a known-groups design with the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, & Dickens, 1992) as the external criterion to determine groups of probable malingering versus nonmalingering. A final sample of 125 criminal defendants, who were administered both the SIRS and the MMPI–2-RF during their evaluations, was examined. The results indicated that the two MMPI–2-RF validity scales specifically designed to detect overreported psychopathology, F-r and FP-r, best differentiated between the malingering and nonmalingering groups. These scales added incremental predictive utility to one another in this differentiation. Classification accuracy statistics substantiated the recommended cut scores in the MMPI–2-RF manual (Ben-Porath & Tellegen, 2008) in this forensic setting. Implications for these results in terms of forensic assessment and detection of malingering are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
