Female zebra finches show a preference for male zebra finches over heterospecific males based solely on the auditory cues of males, such as songs. The present study was designed to investigate whether females show a similar preference for male zebra finches based solely on visual cues. Using a Y-maze apparatus, social preference of female zebra finches was studied between male zebra finches and male Bengalese finches in three experiments. In experiment 1, where female zebra finches could see and hear live male zebra finches and male Bengalese finches, the females preferred to associate with the male zebra finches. In experiment 2, using a sound-attenuated experimental apparatus, subjects could see, but not hear, male zebra finches and male Bengalese finches. The subjects did not show a significant preference for associating with zebra finches. In experiment 3, as in experiment 2, females could see live male zebra finches and male Bengalese finches in the sound-attenuated chambers. However, in experiment 3, the subjects also heard prerecorded auditory cues (i.e., songs and calls) of male zebra finches, which were presented simultaneously in both arms of the maze. Although the females could not use the auditory cues to identify the location of the male zebra finches, they preferred to associate with the male zebra finches rather than the male Bengalese finches. These results suggest that visual cues alone were effective in initiating choice behaviors by females and that auditory cues facilitate such visually based choice behaviors.

The ability of four tufted capuchin monkeys (Cebus apella) to recognize the causal connection between seeing and knowing was investigated. The subjects were trained to follow a suggestion about the location of hidden food provided by a trainer who knew where the food was (the knower) in preference to a trainer who did not (the guesser). The experimenter baited one of three opaque containers behind a cardboard screen so that the subjects could not see which of the containers hid the reward. In experiment 1, the knower appeared first in front of the apparatus and looked into each container; next, the guesser appeared but did not look into any containers. Then the knower touched the correct cup while the guesser touched one of the three randomly. The capuchin monkeys gradually learned to reach toward the cup that the knower suggested. In experiment 2, the subjects adapted to a novel variant of the task, in which the guesser touched but did not look into any of the containers. In experiment 3, the monkeys adapted again when the knower and the guesser appeared in a random order. These results suggest that capuchin monkeys can learn to recognize the relationship between seeing and knowing. Accepted after revision: 10 September 2001 Electronic Publication  相似文献

Most of the extant research on welfare reform has neglected to consider the experiences of families in rural settings. Fifty women receiving welfare for their dependent children in a rural community were interviewed about their work experiences and aspirations, barriers to employment and service use, as well as mental health and social support. The findings indicate that the majority of participants were connected to the labor force and expressed positive attitudes about work. Barriers to employment (lack of available jobs, child care) and service use (transportation, inconvenient office hours) were endorsed. Perceived social support was negatively related to depression symptoms and positively related to self-efficacy and self-esteem. The importance of understanding the life experiences of welfare recipients in different contexts is discussed.  相似文献

The objective of the present study was to provide a further validation of the Crisis Support Scale, which is a short scale for measuring social support after a crisis has occurred. The data from eleven trauma studies of 4213 subjects were used to investigate the psychometric properties of the scale and the differences that emerge due to age, gender, and type of trauma. The scale appears to be very robust. Some aspects of crisis support seem to decrease as time goes by while others increase. Women survivors report less support than men both right after the trauma and later on. The younger survivors tend to report the least support in the acute phase although this picture is reversed later on. The various types of trauma have different item profiles, which supports the concurrent validity of the scale.  相似文献

Experiments vary in their ability to distinguish between competing hypotheses. In tests on primate cognition the majority of this variation is due to an experimenter's ability to test primates in valid settings while providing the adequate amount of experimental control. While experimenters studying primate cognition can use methods of control perfected in captivity, it is still very unclear how to design and then objectively evaluate the external validity of new experimental paradigms. I recommend that more effort be allocated to specify how to create relevant test settings for primates. Primate social life is highly competitive. This means that all aspects of primates themselves, including their cognitive abilities, have likely been shaped by the need to out-compete conspecifics. Based on this hypothesis, sophisticated cognitive abilities of primates might best be demonstrated in competitive contexts. Thus, it is suggested that one possible measure of validity is whether investigators integrate a competitive component into their experimental designs. To evaluate this methodological prediction I review the literature on chimpanzee perspective-taking as a case study including several recent studies that include a competitive component in their experimental designs.

This study examined the concurrent and longitudinal associations between stability in bullying and victimization, and social adjustment in childhood and adolescence. Participants were 189 girls and 328 boys who were studied in primary school and in secondary school. The mean age of the participants was 11.1 years in primary school and 14.1 years in secondary school. The measures consisted of peer reported social and personal characteristics. Children who bullied in childhood and adolescence were less liked and more disliked in childhood, and more aggressive and disruptive both in childhood and adolescence, than children who bullied only in childhood or adolescence. Children who bullied or who were victimized only in childhood did not differ largely in adolescence from the children that were never bullies or victims. Children who were victimized in adolescence closely resembled those who were victimized in childhood and adolescence in terms of being liked or disliked, being nominated as a friend, and shyness. The study stresses the need to distinguish between stable and transient bullies and victims.  相似文献

Little work has studied achievement goals in social interaction situations. The present experiment aimed at contributing to this matter by showing the potential of social interaction (in particular disagreement) to moderate the effects of achievement goals on learning. Participants were led to think they interacted with a partner, sharing opinions about a text that they were studying. Mastery and performance goals were manipulated. During the “interaction,” they received either disagreement or agreement from this bogus partner. Results showed that a condition in which mastery goals were induced led to better learning than a performance goal condition only when the partner disagreed. No differences between goal conditions were observed when the partner agreed. Implications for achievement goal research are discussed. Part of this work was conducted during Céline Darnon’s doctoral dissertation under the supervision of Fabrizio Butera, and was written during Céline Darnon’s post-doctorate at the University of Wisconsin-Madison, USA, thanks to a Fulbright fellowship.  相似文献

Effects of two meditation and mindfulness-based spiritual interventions were examined in college undergraduates (N=44). Compared to a control group, both interventions decreased negative religious coping (d=−0.80, p<.01) and images of God as mainly controlling (d=−.73, p<.01). One intervention provided more training in tools for learning from community and tradition-based spiritual exemplars. It produced gains in famous or traditional spiritual exemplars’ perceived influence (d=+.81, p<.05) and availability (d=+.66, p<.10), in self-efficacy for learning from spiritual exemplars (d=+.92, p<.05), and in nonmaterialistic aspirations (d=+0.65, p<.05).  相似文献

Individuals diagnosed with autism suffer from numerous social, affective and linguistic impairments. It has also been suggested that they have a global imitation deficit. That hypothesis, however, is compromised by the fact that individuals with autism suffer from various motor impairments. Here we describe an experiment on cognitive imitation, a type of imitation that doesn’t require motor learning. Nine male autistic subjects and 20 typically-developing 3- and 4-year olds were trained to respond, in a prescribed order, to different lists of photographs that were displayed simultaneously on a touch-sensitive monitor. Because the position of the photographs varied randomly from trial to trial, sequences could not be learned by motor imitation. In three different imitation treatments, including a ghost control, autistic subjects learned new sequences more rapidly after observing a model execute those sequences than when they had to learn new sequences entirely by trial and error. Moreover, the performance of autistic subjects did not significantly differ from the performance of typically-developing controls. The result of this and other studies suggests that individuals with autism suffer from a specific novel motor imitation deficit.  相似文献

We tested the efficacy of a social skills training program for the parents of school-aged children experiencing socio-emotional problems. Participating families (N = 42) were randomly assigned to one of three conditions: parent social skills training; parent plus parallel child social skills training; or no-treatment control. The two treatment groups did not differ on any of the outcome measures. Treatment was associated with improvements in parent and child social skills knowledge, parent social problem solving, and child emotional functioning. In follow-up analyses examining mechanisms of change, parental attendance and change in child social skills knowledge predicted response to treatment. Overall, our results highlight the utility of engaging parents as primary participants in the treatment of children’s socio-emotional problems and suggest methods for maximizing the impact of such an intervention.  相似文献
