Intuitive Conceptions of Dead Persons' Mentality: A Cross-Cultural Replication and More

Jesse Bering (2002) investigated how American university students in an interview task conceived of dead persons' mentality immediately after death. He found that different categories of mental states or capacities were conceived differently: psychobiological and perceptual states ceased, whereas emotional, desire, and epistemic states continued. Our Study 1 was a replication of Bering's experiment in a different cultural setting, in which the subjects were Chinese undergraduate students. A similar pattern of results was found. In Study 2, instead of being asked about a dead person's various mental states immediately following the death, participants were asked to judge a dead person's mental states after the person had been dead for 2 days. The overall pattern of participants' responses was not affected by this manipulation, but they did show an increase in attributions of certain mental states to dead agnostics. In addition, a more refined breakdown of responses revealed that individuals tended to judge that, upon death, visual and auditory perception continued, whereas olfactory and gustatory sensation ceased.     

The development of social value orientation across different contexts

This study aimed to explore Chinese children's social value orientation across different ages and contexts. Revised decomposed games were used to measure the social value orientation of 9‐, 11‐, and 14‐year‐old children and college students as an adult group. About half of them were assigned to the hypothetical context of “equal payment group,” providing equal compensation for participation in the study, and the others to the “real payment group,” who got payment according to their own choices in the games. Results showed that 9‐ and 11‐year‐old children's choices differed between the two contexts: They made more prosocial choices in the hypothetical context, and more competitive choices in the “real payment” context. The 14‐year‐olds’ and adults’ choices were not significantly different in the two contexts. These results may imply that by 14 years of age, children have stable social value orientation, and their behavior reflects this value.     

Competition and men’s face preferences

Several studies have examined potentially adaptive shifts and sources of individual differences in women’s face preferences, but relatively few studies have looked for similar findings in men. Evidence suggests that men of higher mate-value may be better placed to compete for relationships with higher-quality women, and that contest competition may influence men’s perceptions of dominance. Here, we looked at the effects of winning/losing in male–male competition on men’s face preferences. Participants were randomly and unknowingly assigned to either win or lose the first-person shooter video game Counter-Strike: Source against an unseen male confederate who could control the outcome through game cheats. We found that, compared to men assigned to the losing condition, men assigned to the winning condition had significantly (p = 0.012) higher preferences for women’s facial femininity. Results suggest that the outcomes of male–male competition may alter men’s mate preferences.     

Reduced willingness to approach genuine smilers in social anxiety explained by potential for social evaluation,not misperception of smile authenticity

ABSTRACT

We investigate perception of, and responses to, facial expression authenticity for the first time in social anxiety, testing genuine and polite smiles. Experiment 1 (N?=?141) found perception of smile authenticity was unaffected, but that approach ratings, which are known to be reduced in social anxiety for happy faces, are more strongly reduced for genuine than polite smiles. Moreover, we found an independent contribution of social anxiety to approach ratings, over and above general negative affect (state/trait anxiety, depression), only for genuine smiles, and not for polite ones. We argue this pattern of results can be explained by genuine smilers signalling greater potential for interaction – and thus greater potential for the scrutiny that is feared in social anxiety – than polite smiles. Experiment 2 established that, relative to polite smilers, genuine smilers are indeed perceived as friendlier and likely to want to talk for longer if approached. Critically, the degree to which individual face items were perceived as wanting to interact correlated strongly with the amount that social anxiety reduced willingness to approach in Experiment 1. We conclude it is the potential for social evaluation and scrutiny signalled by happy expressions, rather than their positive valence, that is important in social anxiety.     

Learning and Affect Following Near‐Miss Outcomes in Simulated Gambling

Gambling near‐misses are non‐rewarded events that resemble a winning configuration. Past research using slot machines has shown that moderate rates of near‐misses increase gambling persistence, but the mechanisms supporting this persistence are unclear. One hypothesis is that near‐misses are mistakenly interpreted as signals of skill acquisition, supporting learning and fuelling the ‘illusion of control’. A slot machine simulation was administered to 60 volunteers, with ratings of the perceived chances of winning, pleasure and motivation to play following particular outcomes. Psychophysiological measures (electrodermal activity and heart rate) were taken, and gambling persistence was measured after 30 trials. Near‐misses were similar to full‐miss outcomes in that they were regarded as unpleasant. However, near‐misses were akin to win outcomes in that they increased motivations to play and electrodermal activity. Learning was evidenced by the expectancy of winning increasing following wins and decreasing after losses. Although there was no overall change in expectancy of winning after near‐misses across all participants, those subjects reporting a greater increase in the expectancy of winning following a near‐miss showed more persistent play, consistent with the learning hypothesis. Greater heart rate acceleration following near‐misses was also associated with persistence. We also observed differential effects of near‐misses where the reel stopped either side of the winning position (‘payline’): motivational effects were restricted to near‐misses stopping before the payline, whereas near‐misses that stopped after the payline were primarily aversive. The payline effects are not predicted by the learning hypothesis and may indicate an affective component to near‐misses, possibly linked to counterfactual processing.

Exposure to violence reduces empathetic responses to other’s pain

Past researches showed that empathy for pain not only triggers a resonance mechanism between other and self, but also is modulated by contextual factors. Using functional magnetic resonance imaging, the present study demonstrated that short-term media violence exposure reduced both pain ratings and also the activation of anterior insula and anterior mid-cingulate cortex to other’s pain. Thus, violence exposure modulated empathic responses to other’s pain based on a physiological desensitization.     

Growth orientation of one-dimensional silicon nanowires prepared by thermal evaporation

One-dimensional silicon nanowires have been grown by thermal evaporation and their growth orientations determined by transmission electron microscopy studies. The nanowires, which are often highly curved in morphology and heavily twinned in microstructure, are crystallographically separated into several sections, each with a characteristic crystallographic orientation along the wire axis. Straight nanowires, or straight sections in a curved nanowire, are found to have non-unique crystallographic orientations when {111} twinning occurs.     

Enhanced mental rotation ability in time-space synesthesia

Time-space synesthesia is a variant of sequence–space synesthesia and involves the involuntary association of months of the year with 2D and 3D spatial forms, such as arcs, circles, and ellipses. Previous studies have revealed conflicting results regarding the association between time-space synesthesia and enhanced spatial processing ability. Here, we tested 15 time-space synesthetes, and 15 non-synesthetic controls matched for age, education, and gender on standard tests of mental rotation ability, spatial working memory, and verbal working memory. Synesthetes performed better than controls on our test of mental rotation, but similarly to controls on tests of spatial and verbal working memory. Results support a dissociation between visuo-spatial imagery and spatial working memory capacity, and suggest time-space synesthesia is associated only with enhanced visuo-spatial imagery. These data are consistent with the time-space connectivity thesis that time-space synesthesia results from enhanced connectivity in the parietal lobe between regions supporting the representation of temporal sequences and those underlying visuo-spatial imagery.
