Affective auditory stimulus database: An expanded version of the International Affective Digitized Sounds (IADS-E)

Using appropriate stimuli to evoke emotions is especially important for researching emotion. Psychologists have provided several standardized affective stimulus databases—such as the International Affective Picture System (IAPS) and the Nencki Affective Picture System (NAPS) as visual stimulus databases, as well as the International Affective Digitized Sounds (IADS) and the Montreal Affective Voices as auditory stimulus databases for emotional experiments. However, considering the limitations of the existing auditory stimulus database studies, research using auditory stimuli is relatively limited compared with the studies using visual stimuli. First, the number of sample sounds is limited, making it difficult to equate across emotional conditions and semantic categories. Second, some artificially created materials (music or human voice) may fail to accurately drive the intended emotional processes. Our principal aim was to expand existing auditory affective sample database to sufficiently cover natural sounds. We asked 207 participants to rate 935 sounds (including the sounds from the IADS-2) using the Self-Assessment Manikin (SAM) and three basic-emotion rating scales. The results showed that emotions in sounds can be distinguished on the affective rating scales, and the stability of the evaluations of sounds revealed that we have successfully provided a larger corpus of natural, emotionally evocative auditory stimuli, covering a wide range of semantic categories. Our expanded, standardized sound sample database may promote a wide range of research in auditory systems and the possible interactions with other sensory modalities, encouraging direct reliable comparisons of outcomes from different researchers in the field of psychology.     

Area-Level Income Inequality and Individual Happiness: Evidence from Japan

In this study, we investigated how area-level income inequality is associated with an individual’s assessment of happiness, based on micro-level data sourced from nationwide surveys in Japan. It was confirmed from our analysis using logit models that individuals who live in areas of high income inequality tend to report themselves as being less happy, even after controlling for various individual and area-level factors. The association between inequality and happiness is modestly significant, regardless of the choice of covariates at an individual level, and stronger at a lower level of perceived happiness. Moreover, sensitivity to inequality differs substantially according to certain individual attributes. Among others, an important implication for social policy is that those with unstable occupational status are more sensitive to inequality. Given that these people tend to be less happy than others, this result indicates the risk that area-level inequality further reduces the well-being of those with unfavorable employment conditions.     

Cultural and linguistic influence on neural bases of 'Theory of Mind': an fMRI study with Japanese bilinguals

Theory of mind (ToM)-our ability to predict behaviors of others in terms of their underlying intentions-has been thought to be universal and invariant across different cultures. However, several ToM studies conducted outside the Anglo-American cultural or linguistic boundaries have obtained mixed results. To examine the influence of culture/language on neural bases of ToM, we studied 16 American English-speaking monolinguals and 16 Japanese-English bilinguals with second-order false-belief story tasks, using functional magnetic resonance imaging (fMRI). Several neural correlates of ToM including medial prefrontal cortex (mPFC) and anterior cingulate cortex (ACC) were recruited by both cultural/linguistic groups. However, some other brain areas including inferior frontal gyrus (IFG) were employed in a culture/language-specific manner, during the ToM tasks. These results suggest that the ways in which adults understand ToM are not entirely universal.     

Does psychosocial stress exacerbate avoidant responses to cancer information in those who are afraid of cancer? A population-based survey among older adults in England

Objective: Communication of cancer information is an important element of cancer control, but cancer fear may lead to information avoidance, especially when coping is low. We examined the association between cancer fear and cancer information avoidance, and tested whether this was exacerbated by psychosocial stress.

Design: Cross-sectional survey of 1258 population-based adults (58–70 years) in England.

Main outcome measures: Cancer fear (intensity and frequency), perceived psychosocial stress and cancer information avoidance. Control variables were age, gender, ethnicity, marital status and education.

Results: A quarter (24%) of respondents avoided cancer information. Ordinal logistic regression analyses showed main effects of psychosocial stress (OR = 1.17, 95% CI 1.07–1.29) and cancer fear: cancer information avoidance was lowest in those with no cancer fear (13%), followed by those with moderate (24%; OR = 2.15, 95% CI: 1.49–3.12), and high cancer fear (35%; OR = 3.90, 95% CI: 2.65–5.73). In the adjusted model, the interaction between cancer fear and stress was significant (OR = 1.14, 95% CI 1.004–1.29, p < .05): 40% of those with high fear/high stress avoided cancer information compared with 29% with high fear/low stress.

Conclusion: Cancer fear and psychosocial stress interact to produce disengagement with cancer-related information, highlighting the importance of affective processes to cancer control efforts.     

Cross-sectional transmission electron microscopy of electrodeposited Ni-P alloys

Abstract

Ultramicrotoming has been employed to prepare thin cross-sections of Ni-P alloys electrodeposited on to a copper substrate. The sections, as thin as 10nm or even less, can be prepared readily with negligible damage to the alloys. Subsequent examination of the ultramicrotomed sections in an analytical transmission electron microscope has revealed that Ni-P alloys of low P content consist of fine layers of different composition and crystallinity. High-resolution transmission electron microscopy of ultramicrotomed sections has also revealed the presence of ordered regions, a few nanometres in size, in the Ni₇₇P₂₃ alloy which has been thought previously to be amorphous.     

workplace deviance in japan: applying an extended model of deterrence

We test an extended deterrence model in a Japanese workplace setting. In addition to formal punishments imposed by managerial authorities, employees contemplating rule violation are assumed to take into account the certainty and severity of two other types of punishment - socially-imposed embarrassment and self-imposed shame. All three threats are proposed to be deterrents to employee noncompliance with organizational rules. Previous studies using this theory, all of which have been conducted in the United States, find that shame is a stronger deterrent to deviance than is embarrassment. Drawing on previous discussions of cultural differences between Japan and the United States, we develop a rationale for predicting that the effect of embarrassment will be stronger in a sample of Japanese than in previous samples of Americans. In fact, the results from the Japanese sample concerning the relative importance of shame and embarrassments as inhibitors of deviance are remarkably similar to previous results from American samples. Implications of this finding are considered for the debate concerning whether deviance results primarily from factors internal or external to the individual.     

Eye movement during facial affect recognition by patients with schizophrenia, using Japanese pictures of facial affect

A possible relationship between recognition of facial affect and aberrant eye movement was examined in patients with schizophrenia. A Japanese version of standard pictures of facial affect was prepared. These pictures of basic emotions (surprise, anger, happiness, disgust, fear, sadness) were shown to 19 schizophrenic patients and 20 healthy controls who identified emotions while their eye movements were measured. The proportion of correct identifications of 'disgust' was significantly lower for schizophrenic patients, their eye fixation time was significantly longer for all pictures of facial affect, and their eye movement speed was slower for some facial affects (surprise, fear, and sadness). One index, eye fixation time for "happiness," showed a significant difference between the high- and low-dosage antipsychotic drug groups. Some expected facial affect recognition disorder was seen in schizophrenic patients responding to the Japanese version of affect pictures, but there was no correlation between facial affect recognition disorder and aberrant eye movement.     

How do Children Evaluate the Gossiper of Negative Gossip?

In this study, we investigated how children evaluate gossipers. There are two conflicting ways in which children evaluate the gossiper of negative gossip about another person. One is that they perceive the gossiper of negative gossip as bad because saying something negative about another person can be seen as indirect aggression. The other is that they perceive the gossiper of negative gossip as good because such gossip is beneficial to regulate their relationship with the gossip's target. To address the issue, we asked 7- and 8-year-olds to choose the gossiper of negative gossip or the gossiper of neutral gossip as a cooperative partner and to distribute resources between the gossipers. We found that the children often did not choose the gossiper of negative gossip as a partner and did not distribute many resources to her, indicating a perception of the negative gossiper as bad. This suggests that children's evaluation of a gossiper is influenced by the valence of gossip rather than the value of gossip.
