The perception of visual emotion: Comparing different measures of awareness

Here, we explore the sensitivity of different awareness scales in revealing conscious reports on visual emotion perception. Participants were exposed to a backward masking task involving fearful faces and asked to rate their conscious awareness in perceiving emotion in facial expression using three different subjective measures: confidence ratings (CRs), with the conventional taxonomy of certainty, the perceptual awareness scale (PAS), through which participants categorize “raw” visual experience, and post-decision wagering (PDW), which involves economic categorization. Our results show that the CR measure was the most exhaustive and the most graded. In contrast, the PAS and PDW measures suggested instead that consciousness of emotional stimuli is dichotomous. Possible explanations of the inconsistency were discussed. Finally, our results also indicate that PDW biases awareness ratings by enhancing first-order accuracy of emotion perception. This effect was possibly a result of higher motivation induced by monetary incentives.     

Short-Term Kinesthetic Training for Sensorimotor Rhythms: Effects in Experts and Amateurs

The authors’ aim was to examine whether short-term kinesthetic training affects the level of sensorimotor rhythm (SMR) in different frequency band: alpha (8–12 Hz), lower beta (12.5–16 Hz) and beta (16.5–20 Hz) during the execution of a motor imagery task of closing and opening the right and the left hand by experts (jugglers, practicing similar exercises on an everyday basis) and amateurs (individuals not practicing any sports). It was found that the performance of short kinesthetic training increases the power of alpha rhythm when executing imagery tasks only in the group of amateurs. Therefore, kinesthetic training may be successfully used as a method increasing the vividness of motor imagery, for example, in tasks involving the control of brain–computer interfaces based on SMR.     

Ambivalence,prejudice and negative behavioural tendencies towards out-groups: The moderating role of attitude basis

Two experiments explored the relations between prejudice (suppression), (cognitive) ambivalence and negative behavioural tendencies towards out-groups. The current work argues that expressing out-group ambivalence based on cognitive, but not affective, information is a strategy to justify one's otherwise suppressed prejudice, which may ultimately “cover” the discriminatory nature of out-group-directed negative behavioural tendencies. Two experiments show that (1) participants evaluating the out-group in a normative context inducing prejudice suppression are more likely to self-report ambivalent beliefs rather than ambivalent emotions concerning the out-group as compared with participants whose prejudice expression is induced and (2) high-prejudice participants compared with low-prejudice participants are more prone to out-group-directed negative behavioural tendencies when these latter are self-reported after the expression of ambivalent beliefs but not ambivalent emotions concerning the out-group, and when the expression of their prejudicial evaluations is salient but not when it is not. In light of the extent to which ambivalent attitudes towards out-groups are often seamlessly integrated into public discourse, the implications of the findings are discussed not only for intergroup research but also at the societal level.     

The Effects of Presenting Multidigit Mathematics Problems in a Realistic Context on Sixth Graders' Problem Solving

Mathematics education and assessments increasingly involve arithmetic problems presented in context: a realistic situation that requires mathematical modeling. This study assessed the effects of such typical school mathematics contexts on two aspects of problem solving: performance and strategy use. Multidigit arithmetic problems presented in two conditions—with and without a realistic context—were solved by 685 sixth graders from The Netherlands. Regarding performance, the same (latent) ability dimension was involved in solving both types of problems, and the presence of a context increased the difficulty level of the division problems but not of other operations. Regarding strategy use, strategy choice and strategy accuracy were not affected by the presence of a problem context. In sum, the presence of a typical context in multidigit arithmetic problems had no marked effects on students' problem-solving behavior, which held for different subgroups of students with respect to language ability and gender.     

Harmful Ideas,The Structure and Consequences of Anti‐Semitic Beliefs in Poland

The harmfulness of anti‐Semitic beliefs is widely discussed in current political and legal debates (e.g., Cutler v. Dorn). At the same time, empirical studies of the psychological consequences of such beliefs are scarce. The present research is an attempt to explore the structure of contemporary anti‐Semitic beliefs in Poland—and to evaluate their predictive role in discriminatory intentions and behavior targeting Jews. Another aim was to determine dispositional, situational, and identity correlates of different forms of anti‐Semitic beliefs and behavior. Study 1, performed on a nation‐wide representative sample of Polish adults (N = 979), suggests a three‐factorial structure of anti‐Semitic beliefs, consisting of: (1) belief in Jewish conspiracy, (2) traditional religious anti‐Judaic beliefs, and (3) secondary anti‐Semitic beliefs, focusing on Holocaust commemoration. Of these three beliefs, belief in Jewish conspiracy was the closest antecedent of anti‐Semitic behavioral intentions. Study 2 (N = 600 Internet users in Poland) confirmed the three‐factor structure of anti‐Semitic beliefs and proved that these beliefs explain actual behavior toward Jews in monetary donations. Both studies show that anti‐Semitic beliefs are related to authoritarian personality characteristics, victimhood‐based social identity, and relative deprivation.     

Drug testing in organizations: Applying Horwitz's theory of the effectiveness of social control

Folk crimes, offenses that do not impair the public identity of offenders as respectable, law‐abiding citizens, were studied among a group of New England shellfishermen. Through observation, it was discovered that a pattern of mutual accommodation between enforcers and violators distinguishes folk crime from other violations of the same law. The subjective interpretation of the offenses and accommodation as a reaction is based on considerations of rule intent, logical implications of relevant rules, costs and consequences of rule invocation for enforcers, evaluation of violators’ motives, perceived consequences of violations, and the imputed identity of violators.     

Neuropsychological Functioning in Children with Medium Chain Acyl Coenzyme A Dehydrogenase Deficiency (MCADD): The Impact of Early Diagnosis and Screening on Outcome

Children with medium chain acyl coenzyme A dehydrogenase deficiency (MCADD) have been reported to be at high risk for neurocognitive deficits. However this has not been systematically studied and little is known about the exact nature of neuropsychological sequelae or of the impact of early diagnosis and screening on outcome. We examined cognitive and adaptive outcome in children with MCADD (N?=?38, age range: 2 years, 2 months – 10 years, 3 months) diagnosed either through a newborn screening program (tandem mass spectrometry/MSMS) or upon clinical presentation. There was no evidence of overall intellectual impairment in either groups but there was some suggestion of poorer verbal and specific executive functioning (i.e., planning) abilities in the unscreened cohorts. Adaptive functioning was relatively intact with the exception of reduced Daily Living Skills in both our screened and unscreened groups. Early diagnosis and greater number of hospitalizations were related to higher verbal, communication, and socialization skills. Overall, our results highlight the importance of early diagnosis and management for children with MCADD.
