The factor structure of the Eysenck Personality Profiler in Russia

One hundred and seventy seven males and 399 females completed a translated short version of the Eysenck Personality Profiler (EPP-S). Two hundred and ninety four Ss also completed the EPQ. By means of item analysis, further shortening of the EPP was achieved, while retaining adequate psychometric characteristics and convergent validity with EPQ scales. Confirmatory factor analysis (CFA) confirmed the Eysenck hierarchical model of personality with three basic dimensions and showed stability of the EPP factor structure across genders and sub-samples of different origin. However, CFA showed that only E and P were independent, while N was correlated with E and P.     

Economic inequality is linked to biased self-perception

People's self-perception biases often lead them to see themselves as better than the average person (a phenomenon known as self-enhancement). This bias varies across cultures, and variations are typically explained using cultural variables, such as individualism versus collectivism. We propose that socioeconomic differences among societies--specifically, relative levels of economic inequality--play an important but unrecognized role in how people evaluate themselves. Evidence for self-enhancement was found in 15 diverse nations, but the magnitude of the bias varied. Greater self-enhancement was found in societies with more income inequality, and income inequality predicted cross-cultural differences in self-enhancement better than did individualism/collectivism. These results indicate that macrosocial differences in the distribution of economic goods are linked to microsocial processes of perceiving the self.     

Reviewers and the Detection of Deceptive Information in Recorded Interviews

Being able to detect deceptive information early is worthwhile for recruiters and other information‐based organizational workers; unfortunately, people generally are not good at detecting deception successfully. We conducted an experiment to determine how successful reviewers can be at detecting deception in several types of dispersed interviews. The results indicated that reviewers were more accurate at detecting deceptive information than were participant interviewers; that a warning about deception's presence improved reviewers' detection accuracy; and that a warning did not have any effect on reviewers' number of false alarms between text and audio media. These findings imply that if reviewers are warned about the possible presence of deception, organizations might be able to minimize the chance of hiring high‐risk job applicants.     

Why additional presentations help identify a stimulus

Nosofsky (1983) reported that additional stimulus presentations within a trial increase discriminability in absolute identification, suggesting that each presentation creates an independent stimulus representation, but it remains unclear whether exposure duration or the formation of independent representations improves discrimination in such conditions. Experiment 1 replicated Nosofsky's result. Experiments 2 (masking the ISI between two-presentations) and 3 (manipulating stimulus duration without changing number of presentations or overall trial duration) ruled out an explanation in terms of extended opportunities for stimulus sampling, from either a sensory buffer during additional ISIs or increased stimulus exposure, respectively. Experiment 4 (comparing two and three-presentations, other factors controlled) provided some limited additional support for Nosofsky's original claim that additional stimulus presentations can create either independent or duplicate representations. Experiments 5 and 6 (both manipulating ISI) demonstrated that a key factor in the additional stimulus presentation effect is the overall trial duration. We discuss the results in relation to models of absolute identification, their relative emphasis on stimulus sampling versus response selection, and the mechanisms by which duplicate representations could be created.     

Bad Woman, Bad Victim? Disentangling the Effects of Victim Stereotypicality, Gender Stereotypicality and Benevolent Sexism on Acquaintance Rape Victim Blame

Based on the assertion that previous research may have inadvertently confounded two stereotypes, we considered the impact of benevolent sexism on rape victim blame in the context of independent manipulations of gender and the perceived genuineness (victim stereotypicality) of an acquaintance rape victim. We predicted that for blame, benevolent sexism may be independently positively associated with gender and victim counter-stereotypicality. Following pilot work, 120 Australian undergraduates read an acquaintance rape scenario. Results indicated that benevolent sexism was only positively associated with blame of the gender counter-stereotypical victim when that victim was also counter-stereotypical in terms of victim stereotypes. This result indicates a more moderate role than previously indicated for benevolent sexism in accounting for rape victim blame.     

What causes alternations in dominance during binocular rivalry?

Several mechanisms have been proposed to account for perceptual alterations during binocular rivalry, including neural adaptation and neural noise. However, the importance of neural adaptation for producing perceptual alterations has been challenged in several articles (Y.-J. Kim, Grabowecky, & Suzuki, 2006; Moreno-Bote, Rinzel, & Rubin, 2007). We devised an “online” adaptation procedure to reexamine the role of adaptation in binocular rivalry. Periods of adaptation inserted into rivalry observation periods parametrically alter the dynamics of rivalry such that increased adaptation duration decreases dominance duration, which cannot be accounted for by neural noise. Analysis of the average dominance durations and their variance (coefficient of variation) provides evidence for an increasingly important role of noise in rivalry alternations as a given dominance period continues in time, consistent with recent computational models.     

Error-statistical elimination of alternative hypotheses

I consider the error-statistical account as both a theory of evidence and as a theory of inference. I seek to show how inferences regarding the truth of hypotheses can be upheld by avoiding a certain kind of alternative hypothesis problem. In addition to the testing of assumptions behind the experimental model, I discuss the role of judgments of implausibility. A benefit of my analysis is that it reveals a continuity in the application of error-statistical assessment to low-level empirical hypotheses and highly general theoretical principles. This last point is illustrated with a brief sketch of the issues involved in the parametric framework analysis of tests of physical theories such as General Relativity and of fundamental physical principles such as the Einstein Equivalence Principle.     

Multisource Assessments of Behavioral Competencies and Selection Interview Performance

This study sought to determine whether and how ratings of leadership in a developmental multisource feedback program compare against those obtained by leadership selection decision makers. Seventy‐seven senior managers received feedback on eight competencies that also formed the basis of a subsequent promotional interview for senior executive positions. Each rating source displayed a unique perspective on the participants, but only the supervisor and peer ratings predicted performance on the interview. As well, peer, subordinate, and self‐ratings failed to improve upon the supervisors' predictions. The results also suggested a general performance factor underlying both the multisource assessments and the interview ratings.     

Empathic deficits and alexithymia in trauma-related impulsive aggression

Our long term interest is to develop a developmental model of impulsive aggression based on a confluence of social, psychological and biological features. This approach incorporates neurobiological research, which has identified language processing deficits as a unique characteristic of impulsive aggressors and extends it to include emotional deficits. As an initial test of this hypothesis, we examined whether empathy and alexithymia were associated with impulsive aggression. Regressions were performed to explore the associations among impaired empathy, alexithymia, impulsive aggression, verbal and physical general aggression. Among impulsive aggressive veterans (n = 38) recruited from a VA trauma clinic, alexithymia predicted impulsive aggression and empathic deficits predicted verbal aggression. Neither emotional awareness deficit predicted general physical aggression in this middle-aged sample. Results suggested that empathic deficits were associated with general verbal aggression, but alexithymia was uniquely associated with impulsive aggression. Consideration of alexithymia in impulsive aggression has implications for its etiology, prevention and treatment. Published in 2008 by John Wiley & Sons, Ltd.
