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

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

The purpose of this study was to examine the predictive validity of a teacher nomination procedure for identifying at- risk children. Two hundred and twenty-five children were nominated by their teachers as well- adjusted (n= 75), socially withdrawn (n=76), or socially aggressive (n=74) during the fourth grade. Five years later, 198 of these children (88%) were located and their adjustment evaluated. Significant differences among the nominated children were found on a variety of measures, including academic grades, sociometric status, and social behavior. In addition, differences in school dropout and delinquent offenses were noted. Results are discussed in terms of the validity of teacher nomination procedures and their utility in identifying at- risk youth. 相似文献

Utilized daily diary data to investigate age differences in the moderation of stressful daily events. Data from 243 fifth- to ninth-grade boys and girls, collected over a period of 1 week, were used to examine the moderation effect that expectation and past experience have upon affective response to daily stressors and uplifts. Responses indicate that across a variety of contexts expected daily events are less upsetting than unexpected events for both children and young adolescents. However, among the older students in the sample expectation of chronic negative events appears to exacerbate, rather than alleviate, their upsetting quality. These findings are discussed in terms of the increase in stress associated with early adolescence and the possibility that the chronic stress experienced during this period diminishes the utility of anticipatory coping. 相似文献

Previous research has tentatively indicated that coercive, ineffective parenting might have a mediating role in the differential impact of marital discord on boys and girls. To further explore this role, we examined the relationship between children's perceptions of marital discord and their evaluations of parental discipline techniques. Ninety-one children aged 8 to 13 years (mean age: 11 years 4 months) were split into high, moderate, and low perceived marital discord on the basis of their responses to the Children's Perceptions Questionnaire (Emery & O'Leary, 1982). The children rated how coercive they believed both mothers and fathers would and should be in three discipline situations. Children with high marital discord indicated that both mothers and fathers would and should use more coercive behavior than did children with low marital discord. The effects of marital discord were stronger for boys than for girls. All children also believed that fathers would and should be more coercive than mothers. Results are discussed in relation to the effects of marital discord on children's social development with regard to sex of the child.Thanks are due to Mike Siegal and Pat Noller for their helpful comments on previous drafts. 相似文献

Discriminative properties of morphine that modulate associations between tastes and lithium chloride
G M Martin M Gans D van der Kooy 《Journal of experimental psychology. Animal behavior processes》1990,16(1):56-68
Wistar rats learned to withhold consumption of a target solution when morphine preceded presentation of the target solution and lithium chloride (LiCl) and to consume the same target solution when saline preceded the presentation of the solution. After this serial feature discrimination training, morphine did not block the formation of a Pavlovian association between saccharin and LiCl but did suppress consumption of familiar tap water. After Pavlovian conditioning, morphine blocked the formation of an association between saccharin and LiCl but did not suppress consumption of a familiar tap water solution. The roles of morphine and saline can be interchanged. It appears that the morphine discriminative stimulus is calling up a representation of neither the conditioned stimulus nor the unconditional stimulus alone, but rather a modified representation of some aspect of their association. 相似文献

Summary In the literature two different views with regard to the time course of activation of recognition units —hypothetical entities that represent identity information —are proposed. Both views are derived from a restricted set of phenomena in visual perception. The first view gets its intuitions from phenomena such as those summarized by Bloch's law; these phenomena show integration or summation of activation over time. This grow-and-grow view assumes that recognition units accumulate activation gradually over times The second view finds its inspiration in phenomena such as Mach-bands and simultaneous contrast; these phenomena show inhibition or steady-state suppression over time. This grow-and-shrink view assumes that the activation levels increase fast initially and then start to decrease.The perception literature strongly suggests that it may be light intensity that determines whether mainly integration (and phenomena such as Bloch's law) or inhibition (and phenomena such as Mach-bands) is obtained. So it is also likely that both information-processing views apply only to a limited range of intensity conditions; the grow-and-grow view to conditions of low-flight intensities, and the grow-and-shrink view to conditions of intermediate-and high-light intensities.It is argued that, to arrive at a complete view, a visual phenomenon that applies to the complete range of light intensities should be taken as a background for generating hypotheses about time courses in visual-information processing. The Broca-Sulzer effect is such a phenomenon. Starting from this phenomenon a simple, synthesizing, information-processing model is derived that is compatible with both the grow-and-grow view and the grow-andshrink view. It is shown that, besides the relevant temporal properties, this model also produces the appropriate spatial properties. 相似文献
