The effect of a flashing visual stimulus on the auditory continuity illusion

The effect of a visual stimulus on the auditory continuity illusion was examined. Observers judged whether a tone that was repeatedly alternated with a band-pass noise was continuous or discontinuous. In most observers, a transient visual stimulus that was synchronized with the onset of the noise increased the limit of illusory continuity in terms of maximum noise duration and maximum tone level. The smaller the asynchrony between the noise onset and the visual stimulus onset, the larger the visual effect on this illusion. On the other hand, detection of a tone added to the noise was not enhanced by the visual stimulus. These results cannot be fully explained by the conventional theory that illusory continuity is created by the decomposition of peripheral excitation produced by the occluding sound.     

Survey Satisficing Biases the Estimation of Moderation Effects

Survey satisficing in online data collection biases the estimation of treatment effects in many ways. Extending the findings of a previous study, which demonstrated that satisficing biased the estimation of main treatment effects, this study also shows that satisficing distorts the estimation of moderation effects. Targeting Japanese adults’ attitudes toward food, this study tests how the effect of country of production (Japan vs. China) is moderated by preexisting ethnocentric attitudes. The results show that while nonsatisficers predictably adjust their attitude toward food based on their preexisting ethnocentric attitude, satisficers stick to their initial stereotypical response. That is, the theoretically predicted moderation effect was observed among nonsatisficers, but not among satisficers, which indicates that satisficing biases not only the estimation of a treatment effect but also that of a moderation effect.     

Attention orienting by eye gaze and arrows reveals flexibility to environmental changes

This study aimed to evaluate the difference in non-predictive cues between gaze and arrows in attention orienting. Attention orienting was investigated with gaze or arrows as separate cues in a simple condition (i.e., block design) in Experiment 1 and in an unpredictable condition (i.e., randomized design) in Experiment 2. Two kinds of sound (voice and tone) stimuli were used as targets. Results showed that gaze and arrow cues induced enhanced attention orienting to a voice versus tone target in the block condition. However, in the randomized condition, enhanced attention orienting to a voice versus tone target was found in gaze but not arrow cues. The congruency of the meaning between a social cue (i.e., gaze) and a social target (i.e., voice) was clear in the randomized but not blocked design, because social gaze and non-social arrow cues were implemented in the same block. Thus, attention orienting might be mediated by the associated relationship of cue–target in a randomized condition, as an enhanced orienting effect was found when the associated relationship of cue–target was strong (i.e., social cue and target). The present study suggests that the difference in attention orienting between gaze and arrows is apparent in a randomized design (the unpredictable condition), and people employ a flexibly strategy of orienting to better respond to environmental changes.     

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.     

Changes in Families’ Caregiving Experiences through Involvement as Participants then Facilitators in a Family Peer‐Education Program for Mental Disorders in Japan

A family peer‐education program for mental disorders was developed in Japan, similar to existing programs in the United States and Hong Kong. Families that serve as facilitators in such programs may enhance their caregiving processes and, thereby, their well‐being. This study's aim was to describe how families’ caregiving experiences change, beginning with the onset of a family member's mental illness, through their involvement in a family group or peer‐education program as participants then facilitators. Thus, this study was conducted in a family peer‐education program for mental disorders in Japan. Group interviews were conducted with 27 facilitators from seven program sites about their experiences before, during, and after becoming facilitators. Interview data were coded and categorized into five stages of caregiving processes: (1) withdrawing and suppressing negative experiences with difficulty and regret; (2) finding comfort through being listened to about negative experiences; (3) supporting participants’ sharing as facilitators; (4) understanding and affirming oneself through repeated sharing of experiences; and (5) finding value and social roles in one's experiences. The third, fourth, and fifth stages were experienced by the facilitators. The value that the facilitators placed on their caregiving experiences changed from negative to positive, which participants regarded as helpful and supportive. We conclude that serving as facilitators may improve families’ caregiving processes.     

Development of a cognitive function test using virtual reality technology: examination in healthy participants

We developed a virtual reality test to assess the cognitive function of Japanese people in near-daily-life environment, namely, a virtual shopping test (VST). In this test, participants were asked to execute shopping tasks using touch panel operations in a “virtual shopping mall.” We examined differences in VST performances among healthy participants of different ages and correlations between VST and screening tests, such as the Mini–Mental State Examination (MMSE) and Everyday Memory Checklist (EMC). We included 285 healthy participants between 20 and 86 years of age in seven age groups. Therefore, each VST index tended to decrease with advancing age; differences among age groups were significant. Most VST indices had a significantly negative correlation with MMSE and significantly positive correlation with EMC. VST may be useful for assessing general cognitive decline; effects of age must be considered for proper interpretation of the VST scores.     

Attitude Transference and Deviant Behavior: A Comparative Study in Japan and the United States

Attitude transference is the term that has come to be used to refer to a key process by which one's personal attitudes approving or disapproving of certain behavior reflect those of his or her primary groups and in turn affect his or her conforming or deviant behavior. Cross-cultural comparisons on this and other issues afforded by previous studies, however, have been limited primarily to examining findings that have used different samples and instructions. Drawing on previous literature on cultural variability in individualism, the present study directly tests the hypotheses that although attitude transference operates similarly across cultures, the effects of parental and peer attitudes toward deviance on one's own attitudes should be weaker and stronger, respectively, in Japan compared to the United States. The analysis of identical survey data from college students in the two societies provides mixed support for the hypotheses.     

Differences in Perceived Levels of Informal Punishments for Noncompliance and Rewards for Compliance: A Comparison of Japanese and American Workers

The current article integrates differential association/social learning theory into Grasmick's extended deterrence theory to propose that rational actors, in deciding whether or not to comply with workplace rules, should be expected to consider not only costs of noncompliance but also rewards of compliance. The cultural differences in perceived levels of informal punishment threats of shame and embarrassment for the rule violations and informal rewards of pride and praise for the rule conformity are then examined in merged samples of employees in Japanese and U.S. hospitals. Consistent with the prediction, these punishment threats and rewards are perceived to be higher and lower, respectively, among Japanese employees than among Americans.     

Faster forgetting contributes to impaired spatial memory in the PDAPP mouse: Deficit in memory retrieval associated with increased sensitivity to interference?

Two experiments were conducted to investigate the possibility of faster forgetting by PDAPP mice (a well-established model of Alzheimer's disease as reported by Games and colleagues in an earlier paper). Experiment 1, using mice aged 13-16 mo, confirmed the presence of a deficit in a spatial reference memory task in the water maze by hemizygous PDAPP mice relative to littermate controls. However, after overtraining to a criterion of equivalent navigational performance, a series of memory retention tests revealed faster forgetting in the PDAPP group. Very limited retraining was sufficient to reinstate good memory in both groups, indicating that their faster forgetting may be due to retrieval failure rather than trace decay. In Experiment 2, 6-mo-old PDAPP and controls were required to learn each of a series of spatial locations to criterion with their memory assessed 10 min after learning each location. No memory deficit was apparent in the PDAPP mice initially, but a deficit built up through the series of locations suggestive of increased sensitivity to interference. Faster forgetting and increased interference may each reflect a difficulty in accessing memory traces. This interpretation of one aspect of the cognitive deficit in human mutant APP mice has parallels to deficits observed in patients with Alzheimer's disease, further supporting the validity of transgenic models of the disease.     

Counteractive control over temptations: Promoting resistance through enhanced perception of conflict and goal value

The present research explored people’s everyday practice of counteractive control. Experience sampling was used to test our prediction that strong temptations would promote self-control. Participants were 237 Japanese citizens with ages ranging from 18 to 69. Results indicated that perceived temptation prompted stronger resistance and restraint of behaviors, compared to those cases where no conflict was perceived. In addition, multilevel path analysis revealed the underlying process such that (a) a strong desire toward temptation intensified perception of conflict; (b) perceived conflict bolstered the value of goals that were in disagreement with the temptation; and (c) highly valued goals promoted self-control (i.e., stronger resistance and hence less yielding to temptation).
