Peer Mentoring schemes tend to be developed as retention strategies, however, they can also serve other purposes (psychosocial or career-related). However, evidence of the effectiveness of these presents mixed results and less is known about the horizontal peer support schemes which may help students capitalize on existing peer relationships. We developed an integrated learning communities (ILC) peer support scheme, building on the theoretical principles of social identity theory, which we embedded within our existing teaching framework and designed functional activities. Collective activities were undertaken to promote the processes of social identity with the intention that these may foster social and academic integration experiences. This intervention was undertaken with an entire cohort of first year undergraduate psychology students. We conducted semi-structured interviews with a self-selected sample of these students (N = 17). Thematic analysis revealed two main themes, each with two sub-themes. These were: “Divergent Experiences” with the sub-themes of “dependent on people” and “types of support”, and “Good idea in principle” with the sub-themes of “Theory ≠ Practice” and “Dependent on student engagement”. Although identifying with a peer group was not transparent in the interviews, the existence of a peer support scheme was perceived positively by students which might explain the success of the newly developed student-led Psychology Society. Indeed, this Psychology Society can provide a lasting framework for further amplification of the student voice. We conclude that our embedded ILC was both feasible and potentially valuable, but it is crucial for the peer support approach to have transactional significance. 相似文献

In this study we assessed habituation and sensitization of the acoustic startle response (ASR) to discern whether intense,
inescapable stress affects nonassociative learning differently in male and female rats. Rats were inescapably stressed 2 hours
per day over 3 consecutive days. ASR magnitudes were measured at several times post-stress (1, 4, 8, and 15 days after cessation).
Females generally showed greater ASR magnitudes (compared to males), but both sexes exhibited short and long-term habituation
across the testing days. ASR magnitudes were only affected by stress in male subjects. The effect in males was an increase
in short-term sensitization of the ASR on post-stress day-4. The results suggest that stressed males and females react differently
to ASR testing, in that stress males appear to develop an exaggerated ASR response over repeated test sessions due to short-term
sensitization. The source of the short-term sensitization is discussed with regards to possible stress-induced enhanced contextual
learning during ASR testing on post-stress day-1. 相似文献

Eighty Ss were first tested for base-level response to a pain-producing stimulus and then were re-tested on the same pain stimulus after receiving 1 of 8 experimental treatments. The 8 treatments were arranged in a 2 x 2 x 2 factorial design: presence or absence of hypnotic induction procedure; presence or absence of instructions for anesthesia; and presence or absence of demands for honest reports. Neither the hypnotic-induction procedure nor the demands for honesty affected the Ss'reports of the degree of pain experienced. The anesthesia instructions--"think of the hand as numb and insensitive as if it were a piece of rubber..."--produced an equal degree of pain reduction in hypnotic and non-hypnotic Ss and in Ss who were and those who were not exposed to demands for honesty. The results indicate that (a) Ss' reports of pain are less affected by demands for honesty and are more closely related to their actual experiences than has been previously assumed and (b) instructions which direct Ss to exercise cognitive control over painful sensory input are effective (with or without 'hypnosis') in reducing the experience of pain. 相似文献

The purpose of this survey is to detect common personality features in people infected with AIDS who have a case history of drug addiction and who live in a situation of social exclusion. The sample comprised 105 male participants from the Autonomous Community of Andalusia, divided into 4 groups: (a) 30 men with AIDS, having an intravenous drug addiction case history and who live in a condition of social exclusion; (b) 30 men with IVDA case history, also living in a situation of social exclusion; (c) 15 men in a social exclusion condition; and (d) 30 men in a condition of social adaptation. The evaluation instruments were an author-designed semi-structured interview and the Multiaxial Clinical Inventory (MCMI-II; Millon, 1987). Although some differences were found, the results indicate that there is no specific personality profile in the "social exclusion" population. People in a condition of social exclusion (AIDS, drug addicts, and poor people) may obtain similar scores in the variables studied, but there is no clear specific personality profile in the excluded population, although there may be certain situations in which the segregated groups present similar behaviors. Furthermore, these behaviors do not always correspond to personality features but are adaptive responses to a harsh and complex reality. 相似文献

Although it is widely known that brain regions such as the prefrontal cortex, the amygdala, and the ventral striatum play
large roles in decision making, their precise contributions remain unclear. Here, we used functional magnetic resonance imaging
and principles of reinforcement learning theory to investigate the relationship between current reinforcements and future
decisions. In the experiment, subjects chose between high-risk (i.e., low probability of a large monetary reward) and low-risk
(high probability of a small reward) decisions. For each subject, we estimated value functions that represented the degree
to which reinforcements affected the value of decision options on the subsequent trial. Individual differences in value functions
predicted not only trial-to-trial behavioral strategies, such as choosing high-risk decisions following high-risk rewards,
but also the relationship between activity in prefrontal and subcortical regions during one trial and the decision made in
the subsequent trial. These findings provide a novel link between behavior and neural activity by demonstrating that value
functions are manifested both in adjustments in behavioral strategies and in the neural activity that accompanies those adjustments. 相似文献

Recent research has indicated that the pro-inflammatory cytokines, particularly interleukin-1beta (IL-1beta), can affect learning and memory. We injected male Sprague-Dawley rats with IL-1beta (1.0, 3.0, or 6.0 microg/kg, i.p.) or saline vehicle, 24h before a single 4-h session of leverpress escape/avoidance conditioning. No effect of IL-1beta at any dose was observed in the number of escape responses across the 4-h session. However, subjects treated with the two lower doses (1.0 and 3.0 microg/kg) of IL-1beta performed more avoidance responses during the final hour of the 4-h session than the other two groups. Subjects treated with the highest dose of IL-1beta (6.0 microg/kg) did not differ from controls. Results are discussed in terms of the possible mechanisms behind the IL-1beta-induced enhancement of learning, as well as the observed dose-response relationship. 相似文献

Personality disorders (PDs) are usually construed as psychiatric categories characterized by a unique configuration of traits and behaviors. To generate clinical hypotheses from normal personality trait scores, profile agreement statistics can be calculated using a prototypical personality profile for each PD. Multimethod data from 1,909 psychiatric patients in the People's Republic of China were used to examine the accuracy of such hypotheses in the Interpretive Report of the Revised NEO Personality Inventory. Profile agreement indices from both self-reports and spouse ratings were significantly related to PD symptom scores derived from questionnaires and clinical interviews. However, accuracy of diagnostic classification was only modest to moderate, probably because PDs are not discrete categorical entities. Together with other literature, these data suggest that the current categorical system should be replaced by a more comprehensive system of personality traits and personality-related problems. 相似文献
