When Intertemporal Rewards Are Hedonic,Larger Units of Wait Time Boost Patience

In intertemporal choices between smaller‐sooner (SS) and larger‐later (LL) rewards, five studies reveal that patience for the LL option is influenced by an interactive effect of the measurement units used to express wait time (large vs. small) and the type of the reward (hedonic vs. utilitarian). Specifically, larger time units boost patience, but more so when rewards are hedonic rather than utilitarian. In line with the numerosity heuristic, the effect of time units on patience is mediated by larger time units shrinking wait time perception. This effect arises because hedonic (vs. utilitarian) rewards promote a reliance on heuristics rather than systematic calculations. Therefore, a more calculative mindset diminishes the effect of units even for hedonic rewards and eliminates the hedonic‐utilitarian asymmetry. These results contribute to research on numerosity, intertemporal choice, and hedonic‐utilitarian differences, and offer a simple tool for practitioners to influence patience.     

The wrongs of racist beliefs

Philosophical Studies - We care not only about how people treat us, but also what they believe of us. If I believe that you’re a bad tipper given your race, I’ve wronged you. But, what...     

Humility: An Emerging Construct in Moral Psychology

The virtue of humility is lauded by most authorities but opinions of what it is, what it includes and what it does not are multifarious. Religious and philosophical traditions in India stress its role in emancipating the ego and providing an understanding for one’s perspective as contrasted against the magnanimity of the Almighty, the Supernatural or the Universe. Most academicians within the scientific psychological realm also look upon humility as a virtue. Accredited as a powerful tool for personal, social and organisational well-being, humility, as a moral construct, deserves a thorough and detailed exploration to reveal what it entails, what its corollaries are and how it can be measured. It is particularly useful in Indian context, as indigenous traditions have always emphasised humility. However, such efforts have remained relatively neglected till recent years. Of course, a few researchers with emphasis on moral and positive psychology have probed and prodded this concept to lay bare its comprising elements and to build tools to measure it. These attempts have been discussed here. Information was culled from surveying the scientific literature of the past four decades from psychological and philosophical journals and handbooks. Its overlap with Indian concept of humility has been discussed, and the unresolved questions about its nuances are put forward for future research endeavour.     

Subordinate Performance, Leader-Subordinate Compatibility, and Exchange Quality in Leader-Member Dyads: A Field Study

A model examining factors related to quality of exchange in leader-member dyads was developed and tested. Subordinates and supervisors in 223 dyads in a manufacturing setting provided demographic data and completed measures of performance and attitude towards work. Results found organization citizenship behaviors, leader-member attitude similarity, and similarity of education to be related to quality of leader-member exchange.     

Racial-Ethnic Differences in Genetic Amniocentesis Uptake

The objective of this study was to determine the role of health beliefs in genetic amniocentesis acceptance in a diverse racial-ethnic population. Participants completed a previously-validated questionnaire consisting of three sections: (1) demographics, (2) amniocentesis knowledge, and (3) health beliefs, which assessed perceived susceptibility, seriousness of potential impact, benefits of testing, and barriers to testing. The results showed that Hispanic women were less likely to accept amniocentesis (51.5% vs. Caucasian 82.8%, African American 82.9%, Asian 82.8%). Education level was the only demographic factor higher among acceptors. Women who accepted amniocentesis had higher perceived seriousness, susceptibility, and benefits HBM scores and higher knowledge scores than women who declined. HBM scores and knowledge predicted the amniocentesis decision correctly 91.5% of the time. Individual health beliefs and knowledge play a greater role in genetic amniocentesis acceptance than do demographic factors such as race-ethnicity.     

Enhanced embodied response following ambiguous emotional processing

It has generally been assumed that high-level cognitive and emotional processes are based on amodal conceptual information. In contrast, however, "embodied simulation" theory states that the perception of an emotional signal can trigger a simulation of the related state in the motor, somatosensory, and affective systems. To study the effect of social context on the mimicry effect predicted by the "embodied simulation" theory, we recorded the electromyographic (EMG) activity of participants when looking at emotional facial expressions. We observed an increase in embodied responses when the participants were exposed to a context involving social valence before seeing the emotional facial expressions. An examination of the dynamic EMG activity induced by two socially relevant emotional expressions (namely joy and anger) revealed enhanced EMG responses of the facial muscles associated with the related social prime (either positive or negative). These results are discussed within the general framework of embodiment theory.
