Eye Movements in Strategic Choice

In risky and other multiattribute choices, the process of choosing is well described by random walk or drift diffusion models in which evidence is accumulated over time to threshold. In strategic choices, level‐k and cognitive hierarchy models have been offered as accounts of the choice process, in which people simulate the choice processes of their opponents or partners. We recorded the eye movements in 2 × 2 symmetric games including dominance‐solvable games like prisoner's dilemma and asymmetric coordination games like stag hunt and hawk–dove. The evidence was most consistent with the accumulation of payoff differences over time: we found longer duration choices with more fixations when payoffs differences were more finely balanced, an emerging bias to gaze more at the payoffs for the action ultimately chosen, and that a simple count of transitions between payoffs—whether or not the comparison is strategically informative—was strongly associated with the final choice. The accumulator models do account for these strategic choice process measures, but the level‐k and cognitive hierarchy models do not. © 2015 The Authors.

Illusory recouplings of onsets and terminations of glide tone components

We present a new auditory illusion, the gap transfer illusion, supported by phenomenological and psychophysical data. In a typical situation, an ascending frequency glide of 2,500 msec with a temporal gap of 100 msec in the middle and a continuously descending frequency glide of 500 msec cross each other at their central positions. These glides move at the same constant speed in logarithmic frequency in opposite directions. The temporal gap in the long glide is perceived as if it were in the short glide. The same kind of subjective transfer of a temporal gap can take place also when the stimulus pattern is reversed in time. This phenomenon suggests that onsets and terminations of glide components behave as if they were independent perceptual elements. We also find that when two long frequency glides are presented successively with a short temporal overlap, a long glide tone covering the whole duration of the pattern and a short tone around the temporal middle can be perceived. To account for these results, we propose an event construction model, in which perceptual onsets and terminations are coupled to construct auditory events and the proximity principle connects these elements.     

Body Dissatisfaction,Need for Social Approval,and Eating Disturbances Among Japanese and American College Women

A total of 171 Japanese and 144 American collegewomen (90% European American, 4% African American, 4%Asian or Asian American, and 2% other) completed theEating Attitudes Test (EAT-26), the Body Dissatisfaction Subscale of the Eating Disorder Inventory(EDI), and the Revised Martin-Larsen Approval MotivationScale (MLAM). Japanese women expressed the greaterdissatisfaction with their body but no more eatingdisturbances than American women. The need for socialapproval predicted the Japanese women's eatingdisturbances after controlling for the effects of bodyfatness (BMI) and body dissatisfaction. BMI was asignificant predictor of eating disturbances for Americanwomen but not for Japanese women. The results werediscussed in terms of their implications forcross-cultural similarities and differences incorrelates of disordered eating.     

Processing and Learning of Japanese Double-Object Active and Causative Sentences: An Error-Feedback Paradigm

Do native speakers always outperform second-language (L2) learners in terms of speech processing accuracy? Surprisingly, the answer to this seemingly obvious question is no according to the study reported here. Indeed, native speakers sometimes make more errors than learners in interpreting their own first-language (L1) speech. In this competition experiment of the double-object active and transitive causative sentence processing strategies, six native Japanese speakers and nine English-speaking learners of Japanese participated. The participants were required to identify the agents of the main lexical verb (“doers”) of a series of Japanese sentences, each consisting of one verb and three noun phrases, in which word order and case-marking cues either competed or were consistent with each other. In the first (pretest) and last (posttest) parts of the study, participants received no feedback about the accuracy of their responses, whereas in the middle part they received immediate feedback. The stimulus sentences were such that a listener could determine the semantic role of noun phrases (actor, causer, or recipient) only by taking into consideration both the case markers and the verb's voice (active vs. causative). Learners of Japanese as a second language (JFLs) demonstrated an evident word order bias. Native Japanese speakers also made surprisingly numerous errors, by imposing the canonical case-marker sequence in reconstructing noncanonical sentences. Indeed some of the native Japanese revealed an even stronger word order bias than the learners, and they committed more errors than learners in interpreting noncanonical word order sentences. The results are explained in terms of the working memory constraint. Directions of further research are discussed.     

Helpful Only in the Abstract?

ABSTRACT— This study tested the hypothesis that empathizing with out-group members is beneficial outside of, but not within, intergroup-contact situations. We predicted that in the context of intergroup interaction, the potential for evaluation would lead individuals' perspective-taking efforts to take on an egocentric and counterproductive flavor. As predicted, when empathy was instantiated during an intergroup exchange, it failed to exert its usual positive effect on intergroup attitudes and led higher-prejudice individuals to derogate an out-group member who was an interaction partner; empathy also blocked the prejudice-reducing influence of intergroup contact. Mediation analyses indicated that activation of negative metastereotypes regarding the out-group's view of the in-group accounted for these effects. The findings, which demonstrate ironic effects of empathy in intergroup interaction, indicate that interventions based on studies of individuals' reactions to out-group members in the abstract might have dramatically different consequences when put into practice in real exchanges between members of different groups.     

Salient Intergroup Ideology and Intergroup Interaction

ABSTRACT— Two experiments examined how rendering different intergroup ideologies salient affects dominant- and minority-group members' behavior during, and experience of, intergroup interactions. We hypothesized that ideologies that encourage an outward focus on appreciating out-group members' distinctive qualities (multiculturalism) would have more positive implications than ideologies that encourage a self-control focus on ignoring social categories and avoiding inappropriate behavior (color blindness and antiracism). As predicted, in both ostensible ( Study 1 ) and actual face-to-face ( Study 2 ) intergroup interactions, the multicultural ideological prompt led dominant- and minority-group members to adopt a more outward focus and hence to direct more positive other-directed comments to an interaction partner who was a member of an out-group. In contrast, the color-blind prompt fostered a prevention orientation in dominant-group members that led them to express negative affect toward their out-group interaction partner. The antiracist prompt had no consistent effects. Implications for efforts to improve intergroup relations are discussed.     

Individuality of Narratives Generated by Individuals: An Investigation Using Four-Panel Comics

In this study, we conducted an empirical research focusing on the generation of stories to obtain a hypothesis on how different the stories that people generate in their daily lives by linking events and situations are. For this purpose, five illustrations that revealed only the first and fourth panels of a four-panel comic were used as stimuli to generate a narrative in which the participants could make a connection between them. A total of 40 stories were obtained from eight participants. As a result, the narrative emerged in a variety of ways, even in events with little personal connection to the participants. This reveals that there are individual differences in the way people generate narratives themselves, despite their relationship with and position on the event. When the stories were typified, none of the participants generated similar stories in all five illustrations. This suggests that, because the combination of stories a person creates about every event is unique, there is only one story about the world, and one about himself/herself.     

Time-shrinking: the process of unilateral temporal assimilation

Our previous research on auditory time perception showed that the duration of empty time intervals shorter than about 250 ms can be underestimated hugely if they are immediately preceded by shorter time intervals. We named this illusion 'time-shrinking' (TS). This study comprises four experiments in which the preceding interval, t1, was followed by a standard interval, t2. When t1 < or = 200 ms, and t1 < or = t2, the underestimation of t2 came into view clearly. The absolute difference between t2 and t1 was the crucial factor for the illusion to appear. The underestimation increased when t2 increased from t1 to t1 + 65 ms, stayed at about 45 ms when t2 was between t1 + 65 ms and t1 + 95 ms, and disappeared suddenly when t2 exceeded t1 + 95 ms. This pattern of results was observed across all values of t1 < or = 200 ms. A model was fit to the data to elucidate the underlying process of the illusion. The model states that the perceived duration difference between t1 and t2 is reduced by cutting mental processing time for t2; in other words, that t2 assimilates to t1.     

Benefits of negative thinking and negative affect: analyses of answers to an open-ended question by Japanese undergraduates

What are the benefits of negative thinking and negative affect? Although previous studies in evolutionary psychology, social psychology, and clinical psychology have clarified the question, there has been no definitive study asking people directly about the perceived benefits. In the present study, 119 Japanese undergraduates were asked how they recognized the benefits of negative thinking and negative affect. Their answers were analyzed qualitatively. The answers were arranged into 30 smaller categories and 12 superordinate ones. The benefits were divided into "benefits to the self" and "benefits to interpersonal relations". Finally, the conditions necessary for the negative thinking and negative affect being benign, and possible cultural differences, were discussed.
