The neural plasticity necessary for acquisition and retention of eyeblink conditioning has been localized to the cerebellum. However, the sources of sensory input to the cerebellum that are necessary for establishing learning-related plasticity have not been identified completely. The inferior colliculus may be a source of sensory input to the cerebellum through its projection to the medial auditory thalamus. The medial auditory thalamus is necessary for eyeblink conditioning in rats and projects to the lateral pontine nuclei, which then project to the cerebellar nuclei and cortex. The current experiment examined the role of the inferior colliculus in auditory eyeblink conditioning. Rats were given bilateral or unilateral (contralateral to the conditioned eye) lesions of the inferior colliculus prior to 10 d of delay eyeblink conditioning with a tone CS. Rats with bilateral or unilateral lesions showed equivalently impaired acquisition. The extent of damage to the contralateral inferior colliculus correlated with several measures of conditioning. The findings indicate that the contralateral inferior colliculus provides auditory input to the cerebellum that is necessary for eyeblink conditioning. 相似文献

Patients with schizophrenia demonstrate dissociation between affective experience and motivated behavior 总被引:2,自引:0,他引:2
Self-reported emotional experience does not differ between patients with schizophrenia and healthy individuals, suggesting that the anhedonia in schizophrenia instead reflects decoupling of affect from motivated behavior. In 2 behavioral conditions, participants with schizophrenia and healthy participants were able to prolong or decrease exposure to stimuli while stimuli were present or alter the likelihood of future exposure to stimuli on the basis of internal representations. They also provided self-reports of affective experience. Patients showed weaker correspondence between behavior and ratings than did comparison participants. The effect was amplified when patients responded on the basis of internal rather than evoked stimulus representations. These data suggest that the motivational deficits in schizophrenia reflect problems in the ability to translate experience into action. 相似文献

The Varieties of Forgiveness Experience: Working toward a Comprehensive Definition of Forgiveness 总被引:1,自引:0,他引:1

The definition of forgiveness was explored in a group of 270 young adults, and the underlying dimensions of their definitions
compared with those of philosophers, theologians and psychological researchers. Three dimensions were identified: orientation
(self, other), direction (passive letting go of negative experiences, active enhancement of positive experiences) and form
(emotion, cognition and behavior). Definitions employing a passive letting go of negative experiences were associated with
more state forgiveness. Gender differences were found in state forgiveness and in the employment of passive vs. active dimensions
of forgiveness.
Dr. Kathleen A. Lawler-Row is Professor of Psychology at East Carolina University. Her work focuses on the physiological and
health correlates of forgiveness. Correspondence to Dr. K. A. Lawler-Row, e-mail: rowk@ecu.edu.

Associations between maternal attachment patterns and cognitive skills at first grade were examined, and mediators of identified associations tested using Phase I and II data from the National Institute of Child Health and Human Development Study of Early Care and Youth Development, a prospective study of 1364 children and families from birth through sixth grade. There were three main findings. First, ambivalent and insecure/other attachment patterns were negative predictors of cognitive skills. Second, the association between ambivalent attachment and cognitive skills was mediated by children's behaviors related to testing. Third, the association between insecure/other attachment and cognitive skills was mediated by children's exploration, maternal instruction, children's social relationships, and children's behaviors related to testing. Implications for attachment theory and education are discussed. 相似文献

Without physical appearance, identification in computer‐mediated communication is relatively ambiguous and may depend on verbal cues such as usernames, content, and/or style. This is important when gender‐linked differences exist in the effects of messages, as in emotional support. This study examined gender attribution for online support providers with male, female, or ambiguous usernames, who provided highly person‐centered (HPC) or low person‐centered (LPC) messages. Participants attributed gender to helpers with gender‐ambiguous names based on HPC versus LPC messages. Female participants preferred HPC helpers over LPC helpers. Unexpectedly, men preferred HPC messages from male and gender‐ambiguous helpers more than they did when HPC messages came from females. Implications follow about computer‐mediated emotional support and theories of computer‐mediated communication and social influence. 相似文献

The number of United States public schools offering single-sex education for girls has increased dramatically in the past decade. Rationales for all-girls schools are diverse and grounded in differing gender ideologies. We examined reasoning about all-girls schools among school stakeholders (i.e., individuals affected by single-sex schools, including students, parents, and teachers) in the Southwestern United States. Specifically, middle school students attending all-girls (n?=?398) and coeducational (n?=?191) schools, mothers of middle school students attending all-girls (n?=?217) and coeducational (n?=?64) schools, and teachers employed at all-girls (n?=?18) and coeducational (n?=?97) middle schools rated the veracity of multiple rationales for girls-only schools. Specifically, we examined rationales for single-sex schooling related to gender differences in learning, gender differences in interests, girls’ ingroup preference, and gender discrimination. Endorsement of rationales differed across participant role (student, parent, teacher) and school type (single-sex, coeducational). Overall, stakeholders affiliated with an all-girls school were more supportive of each rationale than stakeholders affiliated with coeducational schools. Teachers affiliated with the single-sex school strongly endorsed gender differences in learning as a rationale for single-sex schooling. Endorsement of rationales did not vary across participant gender. The implications of these findings for educational policy and the interpretation of research on single-sex schooling are discussed. 相似文献

This study documents the vicarious psychological impact of the 2010 earthquake in Haiti on Haitians living in the United States. The role of coping resources—family, religious, and community support—was explored. The results highlight the importance of family and community as coping strategies to manage such trauma. Este estudio documenta el impacto psicológico vicario que tuvo el terremoto de 2010 en Haití sobre los residentes haitianos que viven en Estados Unidos. Se explora el papel de los recursos de afrontamiento—apoyo familiar, religioso y comunitario. Lo resultados destacan la importancia de la familia y la comunidad como estrategias de afrontamiento para superar un trauma de esas características. 相似文献

This study’s primary purpose was to examine the factor structure of the 20-item Seeking of Noetic Goals (SONG) test via exploratory and confirmatory factor-analytic procedures. An additional objective was to report on the measure’s incremental validity in comparison to the Search scale of the Meaning in Life Questionnaire (MLQ), an alternative measure of search for meaning. This study utilized data from three samples of American undergraduates (N = 908) from a medium-sized southern university. Factor analysis supported a two-factor model of the SONG, with patterns of correlation further suggesting the measure assesses distinct constructs. Multi-group confirmatory factor analysis indicated similar scale structure and item answering in terms of gender. Overall, the first factor yielded reliable scores that correlated significantly and in the expected direction with measures of well-being and psychological distress. The second factor did not yield reliable scores nor did it correlate significantly with many of the other measures administered. However, both factors were shown to significantly predict scores from measures of depression and general psychological distress after controlling for MLQ Search scale scores. We consider the data with respect to SONG scoring and interpretation, and discuss implications of these data for future research. 相似文献
