The processing of Kanizsa-square illusory figures was studied in two experiments with four humans and two chimpanzees. Subjects
of the two species were initially trained to select a Kanizsa-square illusory figure presented in a computerized two-alternative
forced choice task. After training, adding narrow closing segments to the pacman inducers that composed the Kanisza illusory
figures lowered performance in both chimpanzees and humans, suggesting that the discrimination could be controlled by the
perception of illusory forms. A second experiment assessed transfer of performance with five sets of figures in which the
size of the inducers and their separation were manipulated. Only for chimpanzees was performance directly controlled by separation,
suggesting that chimpanzees are more sensitive than humans to the separation between visual elements.

An argument is developed that the purported collectivism in Japanese society generates stronger social bonds in Japan than in the more individualistic United States, which might then explain the lower level of deviance often found in Japan. We test this using survey data from samples of Japanese and American college students on measures of deviance and social bonds. Results indicate that Japanese students engage in significantly less deviance than Americans, and although variables from Hirschi's (1969) social control theory behave similarly across cultures as predictors of deviance, the theory failed to account for the lower level of deviance among Japanese. 相似文献

This study aimed to clarify patterns of poverty among single older men and examine this population's help-seeking preferences. Semi-structured interviews were conducted with 83 older single men in poverty. Three main patterns of poverty were identified: lifelong, job turnover, and retirement. A common characteristic among these patterns indicated that they did not recognize their difficulties as problems. Furthermore, we identified five groups of help-receiving preferences: independent, resignation, mutual-aid, other-oriented, and seeking. Among these, the independent and resignation groups were influenced by past experiences of failing to seek help, which was characteristic of the lifelong pattern type. Furthermore, the mutual-aid and seeking groups were oriented toward positive help-seeking, which was characteristic of the job turnover and retirement pattern types. However, neither group actively sought help for social isolation or lack of social support, suggesting that it would have been challenging to establish social relationships early on in life. Thus, it is important to establish initiatives that enable older people to understand their current state and to think about their future depending on three patterns of poverty. 相似文献

After the 2011 Fukushima nuclear accident, intercultural friction and aversion arose between evacuees and host community residents in relocation areas. We examined whether a belief in group interdependence—the extent to which an individual believes that group function is realized through interdependence with related other groups—is consistent with positive interactions between evacuees and hosts. A door-to-door survey of 77 evacuees and 75 hosts revealed that residents with an integrated social identity interacted favorably with both ingroup and outgroup members, and that a belief in group interdependence was consistent with the integration of social identity between the evacuee and host communities. Those findings suggest that a belief in group interdependence can reduce intercultural conflict by allowing both immigrants and host residents to acquire an integrated social identity without the dilemma of internalizing different cultures into an individual's mind. 相似文献

Strain-induced evolution of ultrafine grains in pure copper was studied in multidirectional forging (MDF) at 195?K. The stress–strain behaviour was characterized by rapid strain hardening during early processing and the rate of strain hardening gradually decreased with straining, leading to an apparent steady-state flow at large cumulative strains of more than 5. The structural changes were associated with the development of high-density microshear bands crossed by MDF. The new fine grains 0.16?µm in size, which was smaller than the subgrain size evolved during early deformation, were evolved primarily at microshear band intersections, and then the new fine grains filled out the whole sample as the number of microshear band intersections increased at large strains. This is essentially similar to continuous dynamic recrystallization. The size of new grains can be expressed by a power law function of flow stress with a grain size exponent of about –0.3. The kinetics of the strain-induced grain evolution is analyzed and the mechanisms are discussed. 相似文献

Abstract The ability of amorphous metallic alloys to resist irradiation-induced structural changes will depend on the composition of the alloy and the particle fluences used. In this paper we show that a fast neutron fluence of 1020 cm?2 can induce local crystallization in a refractory NiTi glass. For specimens irradiated with lower fluences, the mode of crystallization of the amorphous matrix is changed from that of a primary process to a eutectic mechanism. 相似文献

People can discriminate cheaters from cooperators by their appearance. However, successful cheater detection can be thwarted by a posed smile, which cheaters display with greater emotional intensity than cooperators. The present study investigated the underlying neural and cognitive mechanisms of a posed smile, which cheaters use to conceal their anti-social attitude, in terms of hemifacial asymmetries of emotional expressions. Raters (50 women and 50 men) performed trustworthiness judgments on composite faces of cheaters and cooperators, operationally defined by the number of deceptions in an economic game. The left–left composites of cheaters were judged to be more trustworthy than the right–right composites when the models posed a happy expression. This left-hemiface advantage for the happy expression was not observed for cooperators. In addition, the left-hemiface advantage of cheaters disappeared for the angry expression. These results suggest that cheaters used the left hemiface, which is connected to the emotional side of the brain (i.e., the right hemisphere), more effectively than the right hemiface to conceal their anti-social attitude. 相似文献

This study investigated the effectiveness of using special training machines for children with intellectual disabilities to strengthen their body's inner muscles and improve their ability to maintain standing posture and improve walking movement. The participants were 23 high school age boys with intellectual disabilities who had difficulties expressing greetings, and needed to be led by the hand when walking. Four special training machines were used for walking movements, for standing and walking balance, for leg-hip extension, and for ipsilateral movement in a sitting position. Each participant underwent 30 min. of training once a week over a 3-mo. period during school time. Body control ability required to perform each training exercise was improved over the training period. A significant improvement was observed in the 50-m dash, mean 10-m walk time, and 10-m obstacle course walk. The hip joint split angle showed a significant increase. Legal guardians all reported their child had "improved and/or progressed" for each of the targeted movements. 相似文献

This study sought to discover if an optimum 1 cm2 area in the non-damaged right hemisphere (RH) was present, which could temporarily improve naming in chronic, nonfluent aphasia patients when suppressed with repetitive transcranial magnetic stimulation (rTMS). Ten minutes of slow, 1 Hz rTMS was applied to suppress different RH ROIs in eight aphasia cases. Picture naming and response time (RT) were examined before, and immediately after rTMS. In aphasia patients, suppression of right pars triangularis (PTr) led to significant increase in pictures named, and significant decrease in RT. Suppression of right pars opercularis (POp), however, led to significant increase in RT, but no change in number of pictures named. Eight normals named all pictures correctly; similar to aphasia patients, RT significantly decreased following rTMS to suppress right PTr, versus right POp. Differential effects following suppression of right PTr versus right POp suggest different functional roles for these regions. 相似文献

Twenty-two pairs of typically developing toddlers (M = 24.32 months) and their mothers were observed in a play-room solving puzzles during 30 min. The target of the observations was hand-taking gesture. Researchers have thought that this gesture is rare among typically developing children and is more frequent among autistic children. Ten in 22 children showed this gesture in only 30 min. They should know “I can not do it by myself, but my mother can do it.” When we can assume that children know others’ mental mechanism, it might be the origins of a theory of mind. 相似文献
