Previous data from our team have shown that pre-test stress in mice reversed the pattern of memory retrieval in a contextual serial spatial task (CSD; Celerier, A., Pierard, C., Rachbauer, D., Sarrieau, A., & Beracochea, D. (2004). Contextual and serial discriminations: A new learning paradigm to assess simultaneously the effects of acute stress on retrieval of flexible or stable information in mice. Learning and Memory, 11, 196-204). The present study is aimed at determining brain areas which might be critically involved in mediating the stress effect on memory retrieval in the CSD task. For that purpose, we studied hereby the effects of ibotenic acid lesions of either the prefrontal cortex (PFC) or the basolateral amygdala (BLA) in Stressed or Non-Stressed Balb/c mice on memory retrieval in the CSD task. In that task, mice learned two successive spatial discriminations (D1 and D2) within two different internal contexts in a four-hole board. The stressor (electric footshocks) was delivered 5 min before test, occurring 24 h after acquisition. During test, mice were relocated either on the floor of the first or of the second discrimination. Results showed that (i) spatial memory was substantial and remained unaffected both by lesions and stress; (ii) Non-Stressed controls as well as Non-Stressed or Stressed PFC and BLA-lesioned mice remembered accurately D1 but not D2; and (iii) in contrast, Stressed controls accurately remembered D2 but not D1. In parallel to behavioral experiments, we also showed that PFC and BLA lesions did not affect the stress-induced increase of plasma corticosterone levels. All together, PFC and BLA integrity are not necessary for retrieval processes per se; in contrast, the PFC and BLA are critically involved in the mediation of the deleterious stress effects on serial order memory retrieval. 相似文献

Socialization in a neighborhood and community at risk, defined in terms of violence, social alienation, school failure, and disruptive behavior, is a risk factor for the acquisition of antisocial and delinquent behavior. In order to test this hypothesis and examine the underlying mechanisms involved, 346 participants, 155 high-risk and 191 low-risk, aged 11 to 13, that is, under the age of criminal responsibility as established by the Spanish Law 5/2000 were selected. The results reveal that high-risk youngsters had higher rates of antisocial behavior and lower levels of social skills (i.e., greater tendency to externalize attribution of responsibility, fewer conflict resolution strategies, lower self esteem, and a lower degrees of emotional intelligence) in comparison to the lower-risk group. Finally, the results and implications of the study are discussed in the light of designing prevention programs. 相似文献

Three-hundred and twenty written accounts of environmental transgressors were assessed by sequential analysis to reveal their argument streams. The accounts were obtained from the written statements that transgressors are allowed to give during the Spanish administrative process and which were included in files handled by four environmental law enforcement agencies. These agencies are distributed across national, regional, island and municipality jurisdictions. The setting for the study is a highly protected environment in which environmental laws have high salience. Results reveal that transgressors use simple argument streams, consistently more defensive than conciliatory, and questioning the perceived legitimacy of environmental law. It was seen also that the empirical functioning of the explanations related to pursuing emotional/prosocial objectives differs from what was expected from the traditional conceptual definition. Results are discussed in terms of how the assessment of the internal dynamic of the accounts would provide valuable information on transgressors' reasoning in relation to environmental laws. 相似文献

Individual morningness-eveningness differences explain the rhythmic variations of behavioral and biological patterns. Several studies have corroborated that morningness preference increases over adulthood and aging. Adolescents shift their time of day preferences from morningness to eveningness during puberty. The aims of this study were translate to Spanish the Morningness-Eveningness Scale for Children (MESC) and to analyze age and sex differences. A group of 600 adolescents (aged between 12 and 16 years) participated in the study. Psychometric analysis showed that reliability and factor structure were suitable and similar to previous studies. The results indicated a clear decrease of morningness as of 12 years. Boys were more morningness-oriented than girls in several items of the questionnaire. In view of the results, several educational implications are raised. 相似文献

In this work, we analyze various consequences of the phenomenon of mobbing on the health of a work sector with special characteristics: the agro fruit sector. For this purpose, we collected data from a sample of 396 workers (61 men and 331 women) belonging to this sector in the Region of Murcia (Spain). A questionnaire with the following measurement instruments was administered: a Spanish adaptation of the revised Negative Acts Questionnaire (Sáez, García, & Llor, 2003), the Psychosomatic Problems Questionnaire (Hock, 1988), and a measure of absenteeism. The results revealed a significant and positive relation between workplace mobbing and psychosomatic symptoms, but not with absenteeism. The implications of the results for future research are discussed. 相似文献

We examined (1) how interviewers construct fit perceptions about applicants and (2) the relationship between these perceptions and actual hiring recommendations. It was hypothesized that actual demographic similarity and human capital similarity would indirectly affect fit perceptions. These fit perceptions would be predicted by the interviewer's perceived similarity to applicants, mediated by two factors: interviewers' liking of the applicant and interviewers' expectations of applicant performance. Actual interviewer‐applicant dyads (N=118) were studied. The results indicated that the relationship between perceived similarity and fit perceptions is mediated by performance expectations but not by liking. This study provides evidence that interviewers are more rational than previous research suggested. However, the fact that human resource interviewers are more likely to perceive applicants as similar to themselves than line interviewers suggests that interviewers' neutrality is questioned. 相似文献

This study examined the relationship between psychological needs and cognition/behavior patterns at work as measured by the Personality and Preference Inventory – Normative (PAPI‐N) and the five‐factor model of personality as measured by the NEO Five Factor Inventory (NEO‐FFI) in a sample of 91 working adults and 71 psychology undergraduates who worked or had some work experience. Our results showed significant and theoretically congruent correlations between the PAPI‐N scales and the measures of the five‐factor model. These correlations were similar to those found using alternative instruments to measure Murray's needs. Despite the differences in the conceptual origins of the PAPI‐N and the NEO‐FFI and divergences in the aspects of personality measured by the two inventories, joint and interbattery factor analyses showed that most of the needs and cognition/behavior patterns measured by the PAPI‐N can be meaningfully organized within the framework of the five‐factor model. These results provide further empirical evidence for the validity of the five‐factor model and the PAPI‐N, although they also point out personality aspects that are not encompassed by the five‐factor model. 相似文献

Solution strategies as possible explanations of individual and sex differences in a dynamic spatial task 总被引:1,自引:0,他引:1
When individuals perform spatial tasks, individual differences emerge in accuracy and speed as well as in the response patterns used to cope with the task. The purpose of this study is to identify, through empirical criteria, the different response patterns or strategies used by individuals when performing the dynamic spatial task presented in the Spatial Orientation Dynamic Test-Revised (SODT-R). Results show that participants can be classified according to their response patterns. Three different ways of solving a task are described, and their relation to (a) performance factors (response latency, response frequency, and invested time) and (b) ability tests (analytical reasoning, verbal reasoning, and spatial estimation) are investigated. Sex differences in response patterns and performance are also analyzed. It is found that the frequency with which men and women employ each one of the strategies described here, is different and statistically significant. Thus, employed strategy plays an important role when interpreting sex differences on dynamic spatial tasks. 相似文献

The present study investigates stress levels, feelings of insecurity, and coping strategies used by people living near an active volcano in México (Popocatépetl). The sample was composed of 198 adults, who were divided into 4 groups according to the risk zones in which they live. They answered a questionnaire addressing feelings of insecurity regarding volcanic risk, a coping strategies scale, and a stress scale. A significant interaction between active and passive coping strategies and risk zone was found. Higher levels of insecurity feelings regarding volcanic risk were associated with the highest stress levels evoked by facing a volcanic risk. A possible application of this study is at the community‐service level concerning risk prevention. 相似文献
