How does preference reversal appear and disappear? Effects of the evaluation mode

Preference reversal is a systematic change in the preference order between options when different response methods are used (e.g., choice vs. judgment). The present study focuses on procedures used to elicit preferences according to an evaluability hypothesis. Two experiments compared joint vs. separate evaluations and explicit vs. non‐explicit joint evaluations. Subjects had to express preferences between high‐variance gambles (HVGs) and low‐variance gambles (LVGs) either by choosing one gamble to play in a lottery or by assigning gambles minimum selling prices. We show that HVGs are preferred in both choice and pricing conditions when gambles are evaluated separately, and LVGs are preferred in both choice and selling conditions when gambles are evaluated in pairs: i.e., when the evaluation mode is held constant, classic preference reversal disappears. These results support the evaluability hypothesis, and suggest that preferences depend on whether subjects are allowed to compare the options they are asked to choose from or judge, independently of the nature of the scale (i.e., attractiveness vs. minimum selling price) they are required to adopt.

Short-term memory performances during sustained wakefulness in patients with obstructive sleep apnea-hypopnea syndrome

Both working and immediate memories were assessed every 4h by specific short-term memory tasks over sustained wakefulness in 12 patients with obstructive sleep apnea and hypopnea syndrome (OSAHS) and 10 healthy controls. Results indicated that OSAHS patients exhibited lower working memory performances than controls on both backward digit span and complex Sternberg tasks. Speed and accuracy on Sternberg tasks were affected by memory load in both groups. However, immediate memory was not impaired in OSAHS patients. Diurnal and nocturnal SaO(2) were correlated with speed and accuracy high-speed memory scanning performance on Sternberg tasks in patients. These results suggest specific working memory deficits associated with OSAHS over sustained wakefulness with a possible deficiency in the central executive responsible for the higher information processing, in addition to a potentially insufficient storage capacity. Among OSAHS patients, working memory ability involved in high-speed memory scanning may be impaired by chronic hypoxemia.     

Automatic emotion regulation after social exclusion: tuning to positivity

Nine experiments tested competing hypotheses regarding nonconscious affective responses to acute social exclusion and how such responses may relate to positive mental health. The results strongly and consistently indicated that acute social exclusion increased nonconscious positive affect. Compared to nonexcluded participants, excluded participants recalled more positive memories from childhood than did accepted participants (Experiment 1), gave greater weight to positive emotion in their judgments of word similarity (Experiments 2 and 3), and completed more ambiguous word stems with happy words (Experiments 4a and 4b). This process was apparently automatic, as participants asked to imagine exclusion overestimated explicit distress and underestimated implicit positivity (Experiment 3). Four final experiments showed that this automatic emotion regulation process was found among participants low (but not high) in depressive symptoms (Experiments 5 and 6) and among participants high (but not low) in self-esteem (Experiments 7 and 8). These findings suggest that acute exclusion sets in motion an automatic emotion regulation process in which positive emotions become highly accessible, which relates to positive mental health.     

Gender and Job Role Congruence: A Field Study of Trust in Labor Mediators

The extent to which individuals are seen as fulfilling their social roles is related to the extent they are seen as successful in that role. Using social role theory, the congruence of job roles and gender roles was examined among labor mediators, a profession requiring both agentic and communal characteristics. A total of 362 employees and employers involved in a workplace dispute that went to governmental mediation were recruited in Quebec, Canada. Regression analyses assessed how impartiality and empathy contributed to parties’ trust in their mediators for male and female mediators. Comparisons of regression structures suggest that perceptions of gender incongruent job characteristics were better predictors of trust in the mediator than gender congruent characteristics. Theoretical and applied implications are discussed.     

Guidelines for Multicultural Assessment: An Asian Indian American Case Study

Accurate assessment of ethnic minority clients is often hindered by clinician bias and lack of culturally sensitive instruments. Multicultural guidelines can enhance clinician awareness and sensitivity in conducting assessments with diverse populations. These guidelines are illustrated using an Asian Indian American character from Lahiri's (2008) novel Unaccustomed Earth. La evaluación precisa de clientes pertenecientes a minorías étnicas se ve con frecuencia dificultada por el sesgo de los especialistas clínicos y la falta de instrumentos culturalmente sensibles. Las directrices multiculturales pueden ampliar la conciencia de los especialistas y su sensibilidad al llevar a cabo evaluaciones con poblaciones diversas. Estas directrices se ilustran usando un personaje indoasiáticoamericano extraído de la novela Unaccustomed Earth de Lahiri (2008).     

A Review of the Empirical Evidence on Generational Differences in Work Attitudes

Purpose  

This article reviews the evidence for generational differences in work values from time-lag studies (which can separate generation from age/career stage) and cross-sectional studies (which cannot). Understanding generational shifts is especially important given the coming retirement of Baby Boomer workers and their replacement by those born after 1982 (GenMe/GenY/Millennials).     

The Five-Factor Model of Personality at the Facet Level: Association with Antisocial Personality Disorder Symptoms and Prediction of Antisocial Behavior

The association between the Five-Factor Model of personality (FFM) and antisocial personality disorder (APD) symptoms was investigated in a sample of young males with a history of severe antisocial behavior. Results were compared against those of an expert-consensus study (Lynam and Widiger Journal of Abnormal Psychology 110:401–412, 2001) and those of a recent meta-analysis (Samuel and Widiger Clinical Psychology Review 28:1326–1342, 2008) based primarily on non-antisocial samples. A high degree of similarity was observed across the three. Multivariate analysis indicated two FFM facets, Compliance and Activity, to be associated with APD symptoms. The contribution of these facets to the prospective prediction of antisocial behavior over and above that of APD symptoms and past antisocial behavior was evaluated. Compliance alone explained 8.7% of the unique variance in future antisocial behavior.     

“Feeling” the pain of those who are different from us: Modulation of EEG in the mu/alpha range

We explored how apparently painful stimuli and the ability to identify with the person on whom the pain is inflicted modulate EEG suppression in the mu/alpha range (8–12 Hz). In a 2 × 2 design, we presented pictures of hands either experiencing needle pricks or being touched by a Q-tip. In the dissimilar-other condition, the hand was assigned to a patient suffering from a neurological disease in which Q-tips inflicted pain, whereas needle pricks did not. In the similar-other condition, the hand was assigned to a patient who responded to stimulation in the same way as the healthy participant. Participants were instructed to imagine the feeling of the person whose hand was shown and to evaluate his or her affective state. Pain conditions elicited greater EEG suppression than did nonpain conditions, particularly over frontocentral regions. Moreover, an interaction between pain and similarity revealed that for similar others, the pain effect was significant, whereas in the dissimilar-other group, suppression was equally large in the pain and no-pain conditions. We conclude that mu/alpha suppression is elicited both automatically, by observing a situation that is potentially painful for the observer, and by empathy for pain, even if the other person is different from oneself.     

Is the use of sentient animals in basic research justifiable?

Animals can be used in many ways in science and scientific research. Given that society values sentient animals and that basic research is not goal oriented, the question is raised: "Is the use of sentient animals in basic research justifiable?" We explore this in the context of funding issues, outcomes from basic research, and the position of society as a whole on using sentient animals in research that is not goal oriented. We conclude that the use of sentient animals in basic research cannot be justified in light of society's priorities.
