The ability of non-human primates to follow the gaze of other individuals has recently received much attention in comparative
cognition. The aim of the present study was to investigate the emergence of this ability in a chimpanzee infant. The infant
was trained to look at one of two objects, which an experimenter indicated by one of four different cue conditions: (1) tapping
on the target object with a finger; (2) pointing to the target object with a finger; (3) gazing at the target object with
head orientation; or (4) glancing at the target object without head orientation. The subject was given food rewards independently
of its responses under the first three conditions, so that its responses to the objects were not influenced by the rewards.
The glancing condition was tested occasionally, without any reinforcement. By the age of 13 months, the subject showed reliable
following responses to the object that was indicated by the various cues, including glancing alone. Furthermore, additional
tests clearly showed that the subject's performance was controlled by the "social" properties of the experimenter-given cues
but not by the non-social, local-enhancing peripheral properties.

Spontaneous attention to word content versus emotional tone: differences among three cultures 总被引:1,自引:0,他引:1
A Stroop interference task was used to test the hypothesis that people in different cultures are differentially attuned to verbal content vis-à-vis vocal tone in comprehending emotional words. In Study 1, Americans showed greater difficulty ignoring verbal content than ignoring vocal tone (which reveals an attentional bias for verbal content); but Japanese showed greater difficulty ignoring vocal tone than ignoring verbal content (which reveals a bias for vocal tone). In Study 2, Tagalog-English bilinguals in the Philippines showed an attentional bias for vocal tone regardless of the language used, suggesting that the effect is largely cultural rather than linguistic. Implications for culture-and-cognition research are discussed. 相似文献

This study examines the values held by mothers in Japan, Puerto Rico and the U.S. Mainland for their handicapped and nonhandicapped preschoolers in the contexts of home and school. In order to study values, mothers from the three cultures were asked to rank twelve value items relating to four value areas: physical, intrapersonal, interpersonal, and sociocultural. The value rankings were different in the three cultures and depended upon the home and school contexts. The presence of a diagnosed orthopedic and/or neurological impairment in the child had no overall effect on value ratings but did interact with culture and context to influence mothers' values. 相似文献

This paper provides an overview of an interdisciplinary programme of research started more than 20 years ago at the University of Tokyo. A major aim of this programme was (and still is) to develop methods and related forms of quantitative analysis that provide rigorous evaluations of infant behaviour from a particular theoretical perspective. In one part of the programme telethermography is used to measure emotional changes in young infants. Contrary to the accepted view in attachment theory, infants as young as 2–3 months showed evidence of stress following separation from the mother (as indexed by a drop in the skin temperature of the infant's forehead). In another part, we established the presence of interpersonal synchrony between arm movements of the newborn and the speech of the mother and other adults, using computer assisted pattern recognition techniques. On the basis of this finding, we have proposed a simulation model of mother-infant interaction from the perspective of system information theory. In general, our programme of research provides a theoretically driven set of techniques and analytical approaches that may provide deeper insights into early development and parenting. 相似文献

We conducted two studies to examine the hypothesis that residential mobility would evoke anxiety and foster sensitivity to signs of disapproval, such as the disappearance of happiness. American and Japanese participants were asked to watch happy-to-neutral movies and sad-to-neutral movies and judge the point at which they thought that their initial expressions had disappeared. We found that, regardless of cultures, participants who had experienced frequent moving (Study 1) and those asked to imagine and describe a mobile lifestyle of frequent moving (Study 2) judged the disappearance of happy faces faster than those who did not experience or imagine frequent moving. Our results were also in line with the previous finding in which Japanese were more vigilant than Americans in regards to the disappearance of happy faces. Moreover, we found that imagining a mobile lifestyle made participants feel more concerned than when imagining a stable lifestyle. The implications for the social skills needed for people in the globalising world are discussed. 相似文献

An arrangement of the so-called Bergman clusters of atoms in a 2/1 cubic crystalline approximant phase, which is closely related to Frank-Kasper-type icosahedral quasicrystals, in an Al-Zn-Mg alloy system is discussed in detail. The 2/1 cubic structure has eight Bergman clusters in its unit cell and the positions of the clusters can be understood as twelvefold sites in the 2/1 cubic approximant of the three-dimensional Penrose lattice. The atomic clusters are located at vertices of two types of rhombohedron, which are formed by six rhombic planes with an edge length of 3 1/2 a 2 /( 2 + 1) 1/2 and a shorter diagonal of 2 a 2 /( 2 + 1) 1/2 ( is the golden ratio and a is a quasilattice constant), which correspond to half a body diagonal and an edge length respectively of the 1/1 cubic approximant unit cell. The present results provide an important key for understanding the arrangements of atomic clusters in icosahedral quasicrystals. 相似文献

An outgroup homogeneity (OH) effect implies that outgroup members are perceived to be more similar than ingroup members. At present, however, it is not clear whether the OH effect is truly perceptual. Here, we used an Ebbinghaus illusion to demonstrate the OH effect in perception. Participants were presented with one central face that was surrounded by four surrounding faces. The central face was judged to be smaller as the size of the surrounding faces increased, thereby demonstrating an Ebbinghaus illusion. As predicted, however, this illusion was significantly greater when the faces allegedly belonged to an outgroup than when they allegedly belonged to an ingroup. This perceptual OH effect bore no significant relationship with cognitive OH measures. The perceptual versus cognitive OH effects might therefore be mediated by separate mechanisms. 相似文献
