Understanding the physical and interpersonal constraints that afford cooperation during real-world tasks requires consideration
of the fit between the environment and task-relevant dimensions of coactors and the coactors’ fit with each other. In the
present study, we examined how cooperation can emerge during ongoing interaction using the simple task of two actors’ moving
long wooden planks. The system dynamics showed hysteresis: A past-action mode persisted when both solo and joint actions were
possible. Moreover, pairs whose arm spans were both short, both long, or mismatched made action-mode transitions at similar
points, when scaled by a relational measure. The relational measure of plank length to arm span was dictated by the pair member
with the shorter arm span, who, thus, had a greater need to cooperate during the task. The results suggest that understanding
affordances for cooperation requires giving more consideration to constraints imposed by the fit between coactors’ action
capabilities. 相似文献

This paper develops the thesis that personal identity is neither to be taken in terms of an unchanging self-sufficient ‘substance’
nor in terms of selfhood ‘without substance,’ i.e. as fluctuating processes of pure relationality and subject-less activity.
Instead, identity is taken as self-transformation that is bound to particular embodied individuals and surpasses them as individuated entities. The paper is structured in three parts. Part I describes the experiential givenness
of conflicts that support our sense of self-transformation. While the first part develops an inter-subjective topography of
emotional movements, the second part pays attention to their temporal dimension. We work with conflicts and get transformed
by them also in the way we remember them. Part II focuses on the process of self-understanding that accompanies conflicts
and their metamorphosis in memory. Part III compares and discusses different models of a ‘relational ontology’ of the person,
which question the idea that we are defined only by how we define ourselves—just as they question the idea that one’s identity
is independent of how one relates to one’s having changed. 相似文献

Physical activity is generally considered as most relevant for modulating heart rate (HR). The authors show here that HR is not only modulated by physical activity but even more by social contexts. HR modulation in three free-ranging, socially embedded, male greylag geese fitted with implanted radiotransmitters was investigated. Measured HR ranged from 40 beats per minute (bpm) during rest to a maximum over 400 bpm during takeoff. Almost the same maximum HRs (400 bpm) were reached during social interactions, which however, generally require less bodily action. Mean HR during social interactions (agonistic interactions, vocalizations) was significantly higher than during behaviors with a less obvious social context (e.g., resting, comfort or feeding behavior), but with comparable physical activity involved. The authors also found significant and consistent differences in HR between the three focal individuals, probably because of individual behavioral phenotype. Our results show that social context has a strong modulatory effect on the sympathico-adrenergic activity in a social bird and conclude that particularly the latter may pose considerable energetic costs.

The aim of the study was to assess the effects of visual aesthetic perception on event-related potentials (ERPs). Eight subjects assigned an aesthetic judgment (beautiful, neutral, or ugly) and a 10-step beauty estimation to the target stimuli, consisting of famous artistic pictures and geometric shapes. In a further task, the subjects performed a motor response to the previously judged pictures and geometric shapes. ERPs were recorded through 54 scalp electrodes during both tasks. The P3b amplitude was increased during the categorization of the geometric shapes compared to the artistic figures and during the vision of the beautiful targets preceding the motor response. The categorization of the aesthetic qualities of geometrical shapes seems to induce a higher level of attention, while a higher arousal variation was elicited by the recognition of beauty, in any form that was presented. 相似文献

We suggest that social relationships shape the self in different ways, depending on whether persons define themselves as independent or interdependent. While the self of independents is most strongly associated with mental representations of others to whom they are related because of their own deliberate action (e.g. friends), the self of interdependents is most strongly connected with representations of others with whom they share allocated group memberships (e.g. family members). We took both explicit (Study 1) and implicit measures (Studies 2, 3 and 4) on how strongly independent and interdependent selves are associated with self‐chosen versus allocated close others. In Studies 3 and 4, we additionally primed the independent or interdependent self. Both explicit and implicit measures indicated that mental representations of family members were more strongly associated with the interdependent self than with the independent self, while romantic partners and friends were connected with both the independent and interdependent self.

Previous studies have suggested neural disruption and reorganization in adult marijuana users. However, it remains unclear whether these effects persist in adolescents after 28 days of abstinence and, if they do, what Performance x Brain Response interactions occur. Adolescent marijuana users (n=17) and controls (n=17) aged 16-18 years were recruited from local schools. Functional magnetic resonance imaging data were collected after 28 days' monitored abstinence as participants performed a spatial working memory task. Marijuana users show Performance x Brain Response interactions in the bilateral temporal lobes, left anterior cingulate, left parahippocampal gyrus, and right thalamus (clusters >/=1358 microl; p<.05), although groups do not differ on behavioral measures of task performance. Marijuana users show differences in brain response to a spatial working memory task despite adequate performance, suggesting a different approach to the task via altered neural pathways. 相似文献

The results of an exploratory national study carried out in Italy using Osgood's Semantic Differential Scales (Osgood, Suci, & Tannenbaum, 1957) with parents of 100 normal 6- to 11-yr.-old children in mainstream classrooms are reported. The aim was to devise a simple tool to be used to explore parents' perceptions of their children in this age group. Parents were asked to rate "my child" using some of Osgood's Semantic Differential Scales especially adapted for this study. Participants were 97 fathers and 100 mothers. Fathers were 32 to 57 years of age (M = 43.2, SD = 5.4), mothers were 29 to 49 years of age (M = 39.7, SD =4.4). In factor analysis four factors were identified: Activity, Evaluation, Emotions evoked by the child, Personality/Physical contact. Average factor scores were significantly different. There were no significant differences between fathers and mothers on the four factor scores. Children were more positively evaluated the younger they were. 相似文献

The objective of this research was to determine whether the tendency of highly avoidant adults not to recall attachment-related information is best explained through defensive strategies that operate on encoding or retrieval processes. In Study 1 participants listened to an emotionally evocative recording and were given both explicit and implicit tests of their memory for the material. Compared to less avoidant people, highly avoidant people recalled fewer details from the recording and performed worse on an implicit test of their memory for the information. In Study 2 we manipulated people's motivation to retrieve information from memory by offering participants a monetary award for recall. Highly avoidant people recalled less information than less-avoidant people despite the monetary incentive. Taken together, these results suggest that the relative inability of avoidant adults to recall attachment-related information is due to the defensive exclusion of information at the time of encoding rather than the time of retrieval. 相似文献

This project provides information on how nonpatient children perform on the Rorschach test, administered and scored following Exner's guidelines (1995). Lis, Parolin, Zennaro, and Mazzeschi (2001) previously reported initial data for 70 nonpatient children living in Italy who were administered this instrument by graduate and postgraduate students in a 2-year research course at the Psychotherapy School of the University of Padua between July 1998 and February 2001. The current study is an extension of that work and includes information on an additional 153 participants gathered between November 2002 and December 2006. The total number of participants includes 223 individuals, 75 5-7-year-old children in the first level of elementary school, and 148 8-11-year-old children in the second level of elementary school. Exclusion criteria are described, and interrater reliability statistics at the response level for scoring segments are reported using percent agreement and iota. Rorschach Comprehensive System (CS) findings are presented. 相似文献
