Escape and avoidance that are disproportional to the danger of the pertinent stimulus are important clinical problems that are often related to inaccurate (catastrophic) expectations. One possible source of such expectations is a prior, underestimated aversive experience. In the present experiment the hypotheses that underestimated pain leads to escape and that it leads to avoidance were tested. In order to control for the effect of the intensity of the pain stimulus, a control group that received 20 pain stimuli of high intensity was formed. Subjects in the experimental condition received 17 pain stimuli of low intensity and 3 of (unexpectedly) high intensity (experimentally induced underprediction). Underprediction of the high intensity stimulus was significantly related to escape, but not to avoidance. The results suggest that the way in which avoidance was operationalized accounts for this. The strong support of the hypothesized relationship between underpredicted pain and escape is an important finding, however.  相似文献

This paper discusses the neuroanatomy and pathology of facial expression and findings on the neuroanatomical connections between expressions of the face and speech. The facial musculature is briefly dealt with in terms of its innervation by the facial nerve and its relationship to the soft palate at the peripheral system level. After considering the facial nuclei, the supranuclear innervation of volitional and emotional facial expression is reviewed. Then supranuclear relations between facial movements and some speech organs are considered. Finally, attention is paid to aspects of facial paralysis stemming from peripheral and central origins.  相似文献

Mutual influencing processes are assumed to be the basic building blocks in establishing parentchild bonding and in influencing cognitive and language behavior. A study by Jasnow and Feldstein (1986) revealed that, within the temporal domain of speech, preverbal (9-month-old) infants and their mothers exhibit a pattern of mutual influence (attunement) in their average durations of switching pauses. The general purpose of this research was to extend those findings to children with higher verbal functioning. In addition, parent and child genders, nature of the interaction, and specific aspects of parents' personalities, expressiveness, and instrumentality were considered. Each parent interacted with their 4-or 5-year-old son or daughter in each of two conversations—unstructured (social conversation) and structured (task activity). Conversations were processed by an automated computer system yielding objective measure of turns, vocalizations, pauses, and switching-pause durations. To examine interspeaker influence or attunement of temporal speech patterns, influence coefficients were computer for each speaker on a turn-by-turn basis using time series regression. Analysis of these coefficients revealed that: (1) Mutual influence is most evident with switching-pause duration. (2) Structure in the conversation (as defined by the task or parental instrumentality) seems to facilitate attunement for vocalization and switching pause duration. (3) Attunement with girls seems to occur equally well with both parents, while boys exhibit a style of temporal patterning influence which suggests greater identification with the father. (4) Expressiveness seems to facilitate attunement to the child's switching-pause duration.  相似文献

This case study concerns an 18-year-old bilingual girl who suffered a radiation lesion in the left (dominant) thalamic and temporal region when she was 4 years old. Language and memory assessment revealed deficits in auditory short-term memory, auditory word comprehension, nonword repetition, syntactic processing, word fluency, and confrontation naming tasks. Both languages (English and Dutch) were found to be affected in a similar manner, despite the fact that one language (English) was acquired before and the other (Dutch) after the period of lesion onset. Most of the deficits appear to be related to verbal (short-term) memory dysfunction. Several hypotheses of subcortical involvement in memory processes are discussed with reference to existing theories in this area.  相似文献

Transparent layer constancy   总被引:1,自引:0,他引:1  
Perceived transparency was studied as a constancy problem. In the episcotister (E-) model of scission, luminances are partitioned into layer and background components; four luminances determine values of two layer parameters that specify constancy of a transparent layer on different backgrounds. The E-model was tested in an experiment in which 12 Ss matched 24 pairs of four-luminance patterns by adjusting two luminances of the comparison pattern. Both the standard and the comparison were perceived as a transparent layer on a checkerboard. The E-model predicts matches when layer values are identical in the two patterns. One parameter was constant, constraining the adjustment along the second dimension. Obtained values corresponded well with E-predictions. Alternative models based on local luminance or average contrast ratios accounted for less variability. Results indicate that transparency models should utilize luminance, not reflectance, as the independent variable.  相似文献

A Gender-role Perspective of Coping and Burnout   总被引:2,自引:0,他引:2  
Cette étude explore la relation entre la dépression, le stress professionnel et les réactions positives chez du personnel scolaire des deux sexes. Les résultats indiquent que les hommes présentent un score significativement plus élevé que celui des femmes à l'échelle de dépersonnalisation du "Mas-lach Burnout Inventory". Alors que les hommes sont plus que les femmes victimes de stress au travail et cela de façon significative, ils ont aussi une plus faible probabilité de faire appel à des techniques de compensation en particulier dans la qualité de Ieur vie quotidienne (les investissements dans les relations amicales et les activités culturelles). D'autres données suggèrent que les femmes sont plus que les hommes capables d'utiliser des stratégies susceptibles de contrecarrer l'effondrement. Chez les hommes, la dépression reléve à la fois du stress professionnel et des enfants: la présence d'enfants élève significativement le niveau de dépression d'un homme.
This study examines the relationship between burnout, work stress, and coping in female and male school personnel. Results indicated that men, compared to women, scored significantly higher on depersonalisation, one of the subscales of the Maslach Burnout Inventory. Men were experiencing significantly greater work stress than women, but were less likely than their female counterparts to employ coping techniques, particularly with regard to their quality of daily life, investment in friends, and cultural activities. Further results suggested that women were better able to use coping strategies to reduce burnout than men. In men, burnout appeared to be a joint function of work stress and children, with the presence of children significantly raising a man's level of burnout.  相似文献

The kinds of messages teachers give students regarding the value of credentials in the job-getting package during a period of high youth unemployment are explored. The response made by students to the credentialling ideology promoted in schools, and their construction of the job-getting formula, are also described. The validity of the two versions of job-getting strategies is considered in the light of evidence provided by a number of empirical research projects. The superiority of student knowledge in this area is used to present a case for a critical and democratic education which appropriates and legitimises the student voice.  相似文献

A multidisciplinary group of genetic and other professionals discuss a complex case of familial conflict over access to genetic information. One twin wishes to know the results of her deceased mother's tests for BRCA1 mutations; a second twin objects to researchers making this information available. As the case discussion unfolds, the apparent facts of this case are called into question and the lines of ethical certainty become less clear.  相似文献

This study examined a research model developed to understand psychological burnout among police officers. Data were collected from 828 men and women in police work using questionnaires completed anonymously. Five groups of predictor variables identified in previous research were considered: individual demographic and situational variables, work stressors, stressful events, work-family conflict and coping responses. Sources of stress (chronic stressors, stressful events, work-family conflict) were significantly related to levels of psychological burnout when individual demographic and situational variables were controlled.  相似文献
