Although geometric reorientation has been extensively studied in numerous species, most research has been conducted in enclosed environments and has focused on use of the geometric property of relative wall length. The current studies investigated how angular information is used by adult humans and pigeons to orient and find a goal in enclosures or arrays that did not provide relative wall length information. In enclosed conditions, the angles formed a diamond shape connected by walls, whereas in array conditions, free-standing angles defined the diamond shape. Adult humans and pigeons were trained to locate two geometrically equivalent corners, either the 60° or 120° angles. Blue feature panels were located in the goal corners so that participants could use either the features or the local angular information to orient. Subsequent tests in manipulated environments isolated the individual cues from training or placed them in conflict with one another. In both enclosed and array environments, humans and pigeons were able to orient when either the angles or the features from training were removed. On conflict tests, female, but not male, adult humans weighted features more heavily than angular geometry. For pigeons, angles were weighted more heavily than features for birds that were trained to go to acute corners, but no difference in weighting was seen for birds trained to go to obtuse corners. These conflict test results were not affected by environment type. A subsequent test with pigeons ruled out an interpretation based on exclusive use of a principal axis rather than angle. Overall, the results indicate that, for both adult humans and pigeons, angular amplitude is a salient orientation cue in both enclosures and arrays of free-standing angles. 相似文献

Fat talk refers to negative body-related conversations between girls or young women. This research aimed to use qualitative data from young women to guide development of a quantitative fat talk measure. In Study 1, a preliminary 62-item questionnaire was developed and administered to 200 female participants. Item analysis resulted in the elimination of items, yielding a final questionnaire with 14 items. Principal components analysis of this questionnaire indicated a single factor. In Study 2, 95 female participants completed the newly developed Fat Talk Questionnaire and theoretically related (e.g., body image) and unrelated (e.g., social desirability) constructs. Additionally, 49 male participants completed the questionnaire to examine known groups validity. In Study 3, 54 participants completed the Fat Talk Questionnaire on two occasions to assess temporal stability. The results showed that the Fat Talk Questionnaire is reliable and valid. The Fat Talk Questionnaire may have important utility in future research. 相似文献

The objective of the present study was to assess whether Body Mass Index or percent body fat was a stronger predictor of health-related quality of life in a community sample of rural Hispanic youth. The sample consisted of 219 Hispanic children and adolescents ages 8–19 years (54.8 % female). Multiple linear regression analysis was conducted with demographics and obesity indicators (BMI, percent body fat) entered as independent variables. Each subscale and summary score of the PedsQL 4.0 Generic Core Scales was a separate dependent variable. Greater percent body fat was associated with lower social functioning in our sample of rural Hispanic youth. BMI percentile was not significantly associated with any of the PedsQL domains. These findings indicate that percent body fat may be more strongly associated with psychosocial functioning than BMI percentile in rural Hispanic youth. 相似文献

Jung's Word Association Test was performed under fMRI conditions by 12 normal subjects. Pooled complexed responses were contrasted against pooled neutral ones. The fMRI activation pattern of this generic ‘complexed response’ was very strong (corrected Z scores ranging from 4.90 to 5.69). The activation pattern in each hemisphere includes mirror neurone areas that track ‘otherness’ (perspectival empathy), anterior insula (both self‐awareness and emotional empathy), and cingulated gyrus (self‐awareness and conflict‐monitoring). These are the sites described by Siegel and colleagues as the ‘resonance circuitry’ in the brain which is central to mindfulness (awareness of self) and empathy (sense of the other), negotiations between self awareness and the ‘internal other’. But there is also an interhemispheric dialogue. Within 3 seconds, the left hemisphere over‐rides the right (at least in our normal subjects). Mindfulness and empathy are central to good psychotherapy, and complexes can be windows of opportunity if left‐brain hegemony is resisted. This study sets foundations for further research: (i) QEEG studies (with their finer temporal resolution) of complexed responses in normal subjects (ii) QEEG and fMRI studies of complexed responses in other conditions, like schizophrenia, PTSD, disorders of self organization. 相似文献

The authors investigated the extent to which the joint-attention behaviors of gaze following, social referencing, and object-directed imitation were related to each other and to infants' vocabulary development in a sample of 60 infants between the ages of 8 and 14 months. Joint-attention skills and vocabulary development were assessed in a laboratory setting. Split-half reliability analyses on the joint-attention measures indicated that the tasks reliably assessed infants' capabilities. In the main analysis, no significant correlations were found among the joint-attention behaviors except for a significant relationship between gaze following and the number of names in infants' productive vocabularies. The overall pattern of results did not replicate results of previous studies (e.g., M. Carpenter, K. Nagell, & M. Tomasello, 1998) that found relationships between various emerging joint-attention behaviors. 相似文献

The health benefits of regular moderate–vigorous intensity physical activity (MVPA) are well established, yet young adults, particularly parents, often show declines in MVPA and may represent a critical population for intervention. Theory-based correlates used to guide future interventions are scant in this population. The purpose of this study was to examine theory of planned behaviour (TPB) belief-level constructs as correlates of directly assessed MVPA across cohorts of couples without children and with their first child over the initial 12?months. Participants were 238 adults (102 not expecting a child, 136 expecting first child) who completed baseline demographics, belief measures of the TPB and seven-day accelerometry, followed by assessments at 6 and 12 months. Results showed select medium-sized belief-PA correlations with sex and cohort interactions. Overall, women had larger affect-based behavioural belief associations with MVPA than men (e.g. PA relieves stress), and among new parents, mothers showed larger associations with control over MVPA than fathers. Mothers also had larger associations between control beliefs and MVPA compared to women without children (e.g. domestic duties, bad weather). Extremely high means and low variability on the behavioural beliefs show limited room for possible changes in intervention while control beliefs had low means suggesting room for change. Interventions targeting control among new mothers may be paramount for increasing MVPA, yet the TPB yielded less insight into the targets for promoting MVPA among young men. 相似文献

Few studies have examined whether certain coping behaviors are associated with physical outcomes following surgery. This prospective, longitudinal study investigated the effect of active and avoidant coping behaviors on two physical outcomes over time, pain and knee function, in a group of patients experiencing knee arthroscopic surgery (n = 81). Structured interviews and physician clinical assessments were conducted preoperatively and at 3 and 24 weeks postoperatively. Coping behavior was assessed during the preoperative interview, and patients were divided into high and low avoidant and active coping groups. Using repeated measures MANCOVA/ANCOVA, avoidant coping was significantly associated with knee pain and active coping was associated with knee function. Serum cortisol levels were available for a patient subset (n = 16); higher cortisol was related to both avoidant coping and poorer functioning during early recovery. Results suggest that these divergent coping behaviors are differentially associated with stress reactivity and physical outcomes in healthy patients undergoing minor knee surgery. 相似文献

An ethnographic portrait of the ‘Western Wall’ (kotel) in Jerusalem, is presented. The kotel is viewed as a pilgrimage site, a ‘place of memory’, and a location linked to a story. Most discussions of the kotel stress its history and archaeology, while this study utilizes ethnography to understand the meanings of the site to a range of social categories. The challenge faced by ethnography is that the social context of the kotel is constituted by Jewish groups all over the world and by cultural distillates stemming from millennia of history. By providing both an overview of kotel activities, and a more detailed examination of several kotel occasions, the paper points to the potential contribution of ethnography to understanding national‐religious shrines. 相似文献

It is unclear which aspects of empathy are shared and which are uniquely affected in autism spectrum disorder (ASD) and conduct disorder (CD) as are the neurobiological correlates of these empathy impairments. The aim of this systematic review is to describe the overlap and specificity of motor, emotional, and cognitive aspects of empathy in children and adolescents with ASD or CD. Motor and cognitive empathy impairments are found in both ASD and CD, yet the specificity seems to differ. In ASD facial mimicry and emotion recognition may be impaired for all basic emotions, whereas in CD this is only the case for negative emotions. Emotional empathy and the role of attention to the eyes therein need further investigation. We hypothesize that impaired motor and cognitive empathy in both disorders are a consequence of lack of attention to the eyes. However, we hypothesize major differences in emotional empathy deficits between ASD and CD, probably due to emotional autonomic and amygdala hyper-responsivity in ASD versus hypo-responsivity in CD, both resulting in lack of attention to the eyes. 相似文献

Cognitivist motivational internalism is the thesis that, if one believes that 'It is right to ϕ', then one will be motivated
to ϕ. This thesis—which captures the practical nature of morality—is in tension with a Humean constraint on belief: belief
cannot motivate action without the assistance of a conceptually independent desire. When defending cognitivist motivational
internalism it is tempting to either argue that the Humean constraint only applies to non-moral beliefs or that moral beliefs
only motivate ceteris paribus. But succumbing to the first temptation places one under a burden to justify what is motivationally exceptional about moral
beliefs and succumbing to the second temptation saddles one with a thesis that fails to do justice to the practicality intuition
that cognitivist motivational internalism is suppose to capture. In this paper, I offer a way of defending cognitivist motivational
internalism, which does not require accepting that there is anything motivationally unusual about moral beliefs. I argue that
no belief satisfies the Humean constraint: all beliefs are capable of motivating without the assistance of a conceptually
independent desire. 相似文献
