Chronic stress facilitates fear conditioning in rats with hippocampal neuronal atrophy and in rats in which the atrophy is prevented with tianeptine, a serotonin re-uptake enhancer. The purpose of this study was to determine whether the lack of dissociation between fear conditioning performance and hippocampal integrity was masked by the presence of endogenous corticosteroids during training. As in previous studies, rats were stressed by daily restraint (6 h/day for 21 days), trained in the conditioning chamber (day 23), and then assessed for conditioned fear (day 25) at a time when hippocampal dendritic atrophy persists. On the training day, half of the control and stressed rats were. injected with metyrapone to reduce corticosterone release. Two hours later, two paired or unpaired presentations of tone and footshock were delivered. Although metyrapone reduced conditioned fear in all rats, only stressed rats showed dissociated fear conditioning (i.e. tone conditioning was reduced while contextual conditioning was eliminated). Chronically stressed rats, regardless of metyrapone treatment displayed more rearing in the open field when tested immediately after the completion of fear conditioning. These data support the hypothesis that increased emotionality and enhanced fear conditioning exhibited by chronically stressed rats maybe due to endogenous corticosterone secretion at the time of fear conditioned training. Moreover,these data suggest that chronic stress impairs hippocampal-dependent processes more robustly than hippocampal-independent processes after metyrapone to reduce corticosterone secretion during aversive training. 相似文献

Previous research demonstrates that social consensus information (information about other people's beliefs) has a powerful influence on intergroup attitudes. The present study examined the influence of consensus information on helping behavior. White participants were provided with favorable or no consensus information about African Americans, and then we assessed their racial attitudes and their willingness to help an African American versus a White person. Replicating previous findings, we found that individuals who received favorable, as compared to no, consensus information had more favorable attitudes toward African Americans. More importantly, our results demonstrated that participants who received favorable consensus information were more likely to help an African American individual than those who did not receive consensus information. Consensus information did not influence behavior toward a White person. In understanding when and why consensus information influences stereotypes and prejudice, we hope to create a useful method to reduce negative intergroup attitudes and behaviors. 相似文献

Two studies examined the extent to which individuals' racial attitudes are influenced more by interdependent others' attitudes than people with whom they do not mutually depend. Study 1 demonstrated that participants significantly changed their racial attitudes when they received disagreement feedback from an ingroup friend, whereas there was no change in attitudes when participants received disagreement feedback from an ingroup stranger, agreement feedback, or no feedback. Furthermore, feelings of interdependence mediated the relationship between feedback from a friend versus stranger and changes in racial attitudes. In Study 2, we manipulated interdependence and found that interdependent partners altered their racial attitudes after receiving disagreement information, whereas independent partners did not. The importance of interdependent others' attitudes in reducing prejudice is discussed. 相似文献

Problem-solving skills training (PSST) has been proposed as a potentially effective addition to behavioral parent training (PT). However, it is not clear whether PSST specifically increases the benefits provided by PT. In this study, PT + PSST was compared to PT + nondirective therapy in a sample of 26 families. All parents received PT. Following this, children received PSST or nondirective therapy. Outcomes included measures of child behavior problems, social skills, and parent stress at posttherapy and a 6-week follow-up. Children in both groups improved over time with few differences between groups. 相似文献

Character is defined broadly by leading authorities, including concepts such as practicing apt behavior and teaching right from wrong. Virtue and moral undertones tend to pervade most experts' use of character, although in secular settings, the notion of ethics is more prominent. Overall, developing in students a desire for the good is how most authorities understand the construct. Implementing character in the public and Christian schools, apart from a Judeo-Christian view of the construct, leaves schools open to values clarification, situational ethics, and other post-modern foundational options. Character development, at least at the conceptual level, is at the heart of all education—Christian or non-Christian. 相似文献

I travel a lot. As I teach and move about through many different cities, come in contact with many kinds of people, see many shapes of mountains, cross many rivers, I carry a certain dust clinging to the hem of my skirt. That dust is from Haiti. And I will never shake it from me. 相似文献

Gazing behavior of 10 three-month-old twin infants (five male and five female) and their mothers during play, bottle feeding, and spoon feeding activities were analyzed. Video-tape equipment was used in the home; data were gathered as naturalistically as possible. Mothers looked at infants for a greater percentage of the total time and for longer durations than infants looked at mothers. A consistency-activation personality theory in which mothers are highly motivated to gaze at infants, but infants seek visual interest by looking away from mother, is suggested to interpret the findings. Both looking and not-looking gazes and mean and median measures of central tendency were shown to be helpful and necessary for the gazing analysis. 相似文献

When using sample data to decide whether two populations differ, laypeople attend to the difference between group means, but largely overlook within-group variability (Obrecht, Chapman, & Gelman, 2007). We show, first, that laypeople know about and use story-implied variability when making pairwise comparisons. Then we demonstrate that participants’ sensitivity to variance in a dataset is boosted when presented in a context that implies consistent variance information. Statistical data were couched in stories about electrical conductivity measurements obtained from element samples (low-variability category) or body weight measurements from samples of peoples (high-variability category). We manipulated, between participants, whether the data variance matched or mismatched the story-implied variability. Participants who received data in a matching context showed high sensitivity to variance, while those in the mismatching condition did not. Laypeople use statistical data to make reasonable inferences when those data are provided in a context that makes sense. 相似文献

The sentinel event theory provides a stepwise approach for building models to understand how negative events can spark health behaviour change. This study tested a preliminary model using the sentinel events method in a sample (N = 300) of smokers who sought care for acute cardiac symptoms. Patients completed measures on: smoking-related causal attribution, perceived severity of the acute illness event, illness-related fear and intentions to quit smoking. Patients were followed up one week after the health event and a seven-day timeline follow back was completed to determine abstinence from tobacco. Structural equation models were performed using average predictor scale scores at baseline, as well as three different time anchors for ratings of illness severity and illness-related fear. Quit intentions, actual illness severity and age were the consistent, positive and independent predictors of seven-day point prevalence abstinence. Additional research on the influences of perceptions and emotional reactions is warranted. 相似文献
