The Japanese Multidimensional Attitudes Scale Toward Persons With Autism Spectrum Disorders1

This study aimed to develop a Japanese Multidimensional Attitudes Scale (J-MAS) as a useful instrument to assess negative attitudes toward persons with autism spectrum disorder among typical Japanese persons. Five hundred and fifty-two Japanese participants completed the Japanese translation of the original version of the MAS, which was derived via the translation/back-translation method. An exploratory factor analysis revealed four factors (Cognitions, Negative Affects, Behaviors, and Calm) that corresponded to the factor model of the original version of the MAS. Nine items were statistically negligible, accordingly. A confirmatory factor analysis revealed that the factor model of the J-MAS is fairly good, and preferable to the factor models of the English, Spanish, French, Korean, and German versions for a sample of typical Japanese persons. These results indicate that the J-MAS provides a valid assessment of attitudes toward persons with autism spectrum disorder among typical Japanese persons.     

Underlying Circuits of Social Support for Bullied Victims: An Appraisal‐Based Perspective on Supportive Communication and Postbullying Adjustment

This study examined the working mechanisms of social support for victims of bullying. Structural equation modeling analyses based on retrospective survey data (N = 448) revealed that the effects of supportive messages varied distinctively, depending on the content of the messages; emotional and esteem support enhanced, but network support impeded, positive reappraisal (the effects of informational support were not significant). Except for that which was related to network support, discrepancy between desired and received support was associated with less positive appraisal. Finally, positive appraisal was found to enhance victims' postbullying adjustment both behaviorally and psychologically. These findings are discussed in terms of their theoretical and practical implications with reference to the literature on social support and coping of bullied victims.     

Perceptual mechanism underlying gaze guidance in chimpanzees and humans

Previous studies comparing eye movements between humans and their closest relatives, chimpanzees, have revealed similarities and differences between the species in terms of where individuals fixate their gaze during free viewing of a naturalistic scene, including social stimuli (e.g. body and face). However, those results were somewhat confounded by the fact that gaze behavior is influenced by low-level stimulus properties (e.g., color and form) and by high-level processes such as social sensitivity and knowledge about the scene. Given the known perceptual and cognitive similarities between chimpanzees and humans, it is expected that such low-level effects do not play a critical role in explaining the high-level similarities and differences between the species. However, there is no quantitative evidence to support this assumption. To estimate the effect of local stimulus saliency on such eye-movement patterns, this study used a well-established bottom-up saliency model. In addition, to elucidate the cues that the viewers use to guide their gaze, we presented scenes in which we had manipulated various stimulus properties. As expected, the saliency model did not fully predict the fixation patterns actually observed in chimpanzees and humans. In addition, both species used multiple cues to fixate socially significant areas such as the face. There was no evidence suggesting any differences between chimpanzees and humans in their responses to low-level saliency. Therefore, this study found a substantial amount of similarity in the perceptual mechanisms underlying gaze guidance in chimpanzees and humans and thereby offers a foundation for direct comparisons between them.     

Inter‐religious dialogue between the Vatican and Sudan

In the modern world, since the end of the Cold War, it seems that the significance of inter‐religious dialogue between Muslims and Christians is increasing. One of the most interesting cases is that of the Vatican and Sudan. There exists an impression that the inter‐religious dialogue between these two parties is going very well But to what extent is this true? This article attempts to find out the true picture of this dialogue. Although the Sudanese Islamists were initially not so keen on the dialogue, they later became more positive and enthusiastic. The Sudanese have developed a vision in international inter‐religious dialogue, while the Vatican seems to have employed a rather delicate policy towards Sudan.     

Perception of shape from shading in chimpanzees (Pan troglodytes) and humans (Homo sapiens)

The perception of shape from shading was tested in two chimpanzees (Pan troglodytes) and five humans (Homo sapiens), using visual search tasks. Subjects were required to select and touch an odd item (target) from among uniform distractors. Humans found the target faster when shading was vertical than when it was horizontal, consistent with results of previous research. Both chimpanzees showed the opposite pattern: they found the target faster when shading was horizontal. The same difference in response was found in texture segregation tasks. This difference between the species could not be explained by head rotation or head shift parallel to the surface of the monitor. Furthermore, when the shaded shape was changed from a circle to a square, or the shading type was changed from gradual to stepwise, the difference in performance between vertical and horizontal shading disappeared in chimpanzees, but persisted in humans. These results suggest that chimpanzees process shading information in a different way from humans. Received: 20 January 1998 / Accepted after revision: 30 March 1998     

TESTS FOR CONTROL BY EXCLUSION AND NEGATIVE STIMULUS RELATIONS OF ARBITRARY MATCHING TO SAMPLE IN A “SYMMETRY-EMERGENT” CHIMPANZEE

In the present experiments, controlling relations in arbitrary matching-to-sample performance were tested in a 9-year-old female chimpanzee who showed statistically significant emergence of symmetry in previous two-choice conditional discrimination experiments. In Experiment 1, a novel (undefined) sample stimulus was followed by a pair of trained (defined) and undefined comparison stimuli to assess the control by exclusion in arbitrary matching. The chimpanzee selected the undefined shape comparison, excluding the defined one, in color-sample-to-shape-comparison probe trials, although stimulus preferences were relatively stronger than control by exclusion in shape-sample trials. An additional test for control by relations of the sample to the positive comparison (S+ control) showed that her behavior was also under the control of relations of the sample to the positive comparison. In Experiment 2, a defined sample was followed by a pair of negatively defined and undefined comparisons to test control by the relations of the sample to the negative comparison. (S- control). The subject selected undefined comparisons in both color-shape and shape-color test trials. These results clearly indicate that the conditional discrimination behavior of this “symmetry-emergent” chimpanzee was under both S+ and S- control. Furthermore, her performance was also under control by exclusion in color-shape arbitrary matching, unlike other chimpanzees who showed no evidence of symmetry but only S+ control of arbitrary matching.     

Roots of smile: a preterm neonates' study

Twenty-two preterm neonates were observed 1 h per neonate in the NICU. Ninety-five spontaneous smiles were recorded. Younger and smaller neonates showed more and longer spontaneous smiles than older and larger. The youngest neonate was 200 days from conception on the observational day. She was 511 g. This infant showed spontaneous smiles. The roots of spontaneous smiles are discussed.     

Are the windows to the soul the same in the East and West? Cultural differences in using the eyes and mouth as cues to recognize emotions in Japan and the United States

The current research investigated the hypothesis that, depending on an individual’s cultural background, facial cues in different parts of the face are weighted differently when interpreting emotions. Given that the eyes are more difficult to control than the mouth when people express emotions, we predicted that individuals in cultures where emotional subduction is the norm (such as Japan) would focus more strongly on the eyes than the mouth when interpreting others’ emotions. By contrast, we predicted that people in cultures where overt emotional expression is the norm (such as the US) would tend to interpret emotions based on the position of the mouth, because it is the most expressive part of the face. This hypothesis was confirmed in two studies, one using illustrated faces, and one using edited facial expressions from real people, in which emotional expressions in the eyes and mouth were independently manipulated. Implications for our understanding of cross-cultural psychology, as well of the psychology of emotional interpretation, are discussed.     

Spontaneous smile and spontaneous laugh: an intensive longitudinal case study

One male infant was observed from the day of his birth to the end of the 6th month. Total observation days were 171 days, and total observation time was 329 h 25 min and 35s. Five hundred and sixty-five spontaneous smiles and 15 spontaneous laughs (smiles accompanied by vocal sounds) were observed. Developmental psychologists have thought that spontaneous smiles integrate at about 3 months, but spontaneous smiles were recorded even in the 6th month. The percentage of bilateral smiles increased from the 2nd month. This is the first intensive longitudinal study on spontaneous smiles and spontaneous laughs.
