Reduction of the flash-lag effect in terms of active observation

In the present study, we investigated how observers’ control of stimulus change affects temporal and spatial aspects of visual perception. We compared the illusory flash-lag effects for automatic movement of the stimulus with stimulus movement that was controlled by the observers’ active manipulation of a computer mouse (Experiments 1, 2, and 5), a keyboard (Experiment 3), or a trackball (Experiment 4). We found that the flash-lag effect was significantly reduced when the observer was familiar with the directional relationship between the mouse movement and stimulus movement on a front parallel display (Experiments 1 and 2) and that, although the unfamiliar directional relationship between the mouse movement and stimulus movement increased the flash-lag effect at the beginning of the experimental session, the repetitive observation with the same unfamiliar directional relationship reduced the flash-lag effect (Experiment 5). We found no consistent reduction of the flash-lag effect with the use of a keyboard or a trackball (Experiments 3 and 4). These results suggest that the learning of a specific directional relationship between a proprioceptive signal of hand movements and a visual signal of stimulus movements is necessary for the reduction of the flash-lag effect.     

Felt Understanding as a Bridge between Close Relationships and Subjective Well-Being: Antecedents and Consequences Across Individuals and Cultures

The literatures on close relationships and subjective well-being have received enormous attention in personality and social psychology over the last two decades. However, despite the well-known link between the quality of social relationships and subjective well-being, these two research traditions have developed relatively independent of one other. Research on felt understanding and misunderstanding attempts to integrate these two related but relatively distinct literatures. To this end, the current review summarizes major recent findings on the antecedents and consequences of felt understanding and misunderstanding and highlights important cultural and individual differences in the processes involving felt understanding and misunderstanding.     

Salivary conditioning with antennal gustatory unconditioned stimulus in an insect

Classical conditioning of olfactory conditioning stimulus (CS) with gustatory unconditioned stimulus (US) in insects has been used as a pertinent model for elucidation of neural mechanisms underlying learning and memory. However, a conditioning system in which stable intracellular recordings from brain neurons are feasibly obtained while monitoring the conditioning effect has remained to be established. Recently, we found classical conditioning of salivation in cockroaches Periplaneta americana, in which an odor was associated with sucrose solution applied to the mouth, and this conditioning could be monitored by activities of salivary neurons. Application of gustatory US to the mouth, however, leads to feeding movement accompanying a movement of the brain that prevents stable recordings from brain neurons. Here we investigated whether a gustatory stimulus presented to an antenna could serve as an effective US for producing salivary conditioning. Presentation of sucrose or sodium chloride solution to an antenna induced salivation and also increased activities of salivary neurons. A single pairing trial of an odor with antennal presentation of sucrose or sodium chloride solution produced conditioning of salivation or of activities of salivary neurons. Five pairing trials led to a conditioning effect that lasted for one day. Water or tactile stimulus presented to an antenna was not effective for producing conditioning. The results demonstrate that gustatory US presented to an antenna is as effective as that presented to the mouth for producing salivary conditioning. This conditioning system provides a useful model for studying the neural basis of learning at the level of singly identifiable neurons.     

The psychological consequences of income inequality

In this paper, we review and integrate the contemporary literature on the societal effects of income inequality, drawing on social, personality, developmental, and organizational psychology, sociology, political science, economics, and public health. Living in highly unequal regimes is associated with both increased mistrust and increased anxiety about social status; these psychological mechanisms help explain some of the negative outcomes associated with income inequality, such as lower happiness, lower social cohesion, weaker morality, higher mortality, worse health, and weaker governance.     

Income inequality and happiness

Using General Social Survey data from 1972 to 2008, we found that Americans were on average happier in the years with less national income inequality than in the years with more national income inequality. We further demonstrated that this inverse relation between income inequality and happiness was explained by perceived fairness and general trust. That is, Americans trusted other people less and perceived other people to be less fair in the years with more national income inequality than in the years with less national income inequality. The negative association between income inequality and happiness held for lower-income respondents, but not for higher-income respondents. Most important, we found that the negative link between income inequality and the happiness of lower-income respondents was explained not by lower household income, but by perceived unfairness and lack of trust.     

Was he happy? Cultural difference in conceptions of Jesus

In two studies, we examined whether (a) conceptions of Jesus would differ between Koreans and Americans, and whether (b) national differences in self-reported personality and well-being are mediated by the cultural norm for personality and well-being. Because there is only one Jesus, different conceptions held by Koreans and Americans are likely to reflect cultural construction processes. In Study 1, we asked Korean and American participants to engage in a free association task with Jesus as a target. Americans associated Jesus with primarily positive connotations (“awesome”) and rarely with negative connotations (“pain”), whereas Koreans associated Jesus with both positive and negative connotations. In Study 2, we asked Korean and American participants to rate Jesus and themselves using personality and well-being scales. Americans rated both Jesus and themselves as more extraverted, agreeable, conscientious, open, and happier than did Koreans. Most important, national differences in self-reported agreeableness, conscientiousness, openness, and happiness were partially mediated by conceptions of Jesus.     

The predictive value of daily vs. retrospective well-being judgments in relationship stability

The present study examined the role of daily and retrospective judgments of well-being and relationship satisfaction in relationship longevity. Participating couples completed a 14-day diary report of well-being and relationship satisfaction. After the daily diary survey, they evaluated the 14-day period. Participants also rated their global relationship satisfaction at that time. Retrospective judgments of daily well-being predicted later relationship status better than daily ratings of well-being did, whereas daily ratings of relationship domain satisfaction predicted later status better than retrospective judgments of daily relationship domain satisfaction did. Furthermore, global relationship satisfaction predicted later relationship status better than daily ratings of relationship domain satisfaction did. In general, global, summary judgments had a greater predictive value of future relationship status than did specific, daily judgments. Finally, synchronicity of daily fluctuations of well-being between partners predicted later relationship status.     

The socioecological model of procommunity action: the benefits of residential stability

The authors conducted 3 studies to test a socioecological model of procommunity action. Study 1 showed that residents of stable communities purchased a "critical habitat" license plate to support preservation of the environment in their home state more often than did residents of mobile communities. Study 2 demonstrated that home game baseball attendance was less dependent on the team's record in stable cities than in mobile cities. Study 3, an experiment, showed that residential stability had a causal impact on procommunity behavior. Moreover, the effect of stability was partially mediated by identification with the "community." Together, these studies indicate that residential stability can lead to stronger identification with one's community, which, in turn, leads to more procommunity behaviors.     

The value-congruence model of memory for emotional experiences: an explanation for cultural differences in emotional self-reports

In 3 studies, the authors found support for the value-congruence model that accounts for cultural variations in memory for emotional experiences. In Study 1, the authors found that in the made-in-the-U.S. scenario condition, European Americans were more accurate than were Asian Americans in their retrospective frequency judgments of emotions. However, in the made-in-Japan scenario condition, European Americans were less accurate than were Asian Americans. In Study 2, the authors demonstrated that value orientation mediates the CulturexType of Event congruence effect. In Study 3 (a daily event sampling study), the authors showed that the congruence effect was explained by the importance of parental approval. In sum, emotional events congruent with personal values remain in memory longer and influence retrospective frequency judgments of emotion more than do incongruent events.     

Cross-cultural Protective Effects of Neighborhood Collective Efficacy on Antisocial Behaviors: Mediating Role of Social Information Processing

Studies on the prevention of antisocial behavior in neighborhoods through efficacious social control have focused on collective efficacy as the theoretical mechanism by which children at the community level can be successfully socialized to develop an aversion to antisocial behaviors. We hypothesized that the effect of collective efficacy within communities on antisocial behaviors could be mediated by social-information-processing biases and tested the generality of these mediation effects for undergraduates (N = 929) in Japan, China, South Korea, and the United States, countries with widely varying cultures and political systems. Structural equation modeling revealed that the effects of collective efficacy on antisocial behaviors were perfectly mediated by social-information-processing biases. Findings also confirmed the generality of these mediational effects in all four countries investigated.
