This study aims to discover whether observers with the same cultural background as the inhabitant of a bedroom perceive common characteristics among the inhabitants. The study was carried out with 107 females who were asked to assess the inhabitants of eight bedrooms. Several slides of each bedroom were shown to participants and they had to choose from a list of seventy-six characteristics those that defined the resident of each bedroom. Results revealed that socio-demographic variables thus attributed coincided with the profiles of the inhabitants. A correspondence analysis brought to light a dimension linked to affective aspects, which was more prominent among women; whereas among men the characteristics thus attributed were more linked to practical aspects and to difficulties for social interaction. A second study was conducted to determine whether gender stereotype had any influence on the result of the previous study. The outcomes showed that this stereotype did not have any effect on the participants' judgments. 相似文献

Competence to be executed evaluations in effect can prevent an execution or remove the last meaningful impediment to it. Forensic psychiatrists have primary duties to the legal system and truth and honesty, but like all other areas of medical consultation also should balance conflicting secondary traditional medical ethical duties. Participation in a legally authorized execution so violates medical roles, that it is ethically prohibited by the American Medical Association and American Psychiatric Association. This prohibition includes treatment intended to restore competence to be executed. However, despite the primary treatment intent otherwise being appropriate ethically, like relieving suffering or fostering prison safety, if competence to be executed almost predictably would be a treatment result, at least the risk of this result should be considered ethically as if it were intended. In contrast, competence to be executed assessments can be ethical. Diamond's approach of performing honest evaluations only for the defense is an ethical option for such assessments. However, it is challenging to persuade judges and juries of the objectivity of such honest legitimate assessments. Most practitioners therefore likely would consider assessing competence to be executed for either side. This ethically hazardous position necessitates sensitivity to potentially seriously conflicting duties and roles. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

The present study examines the reliability, factor structure, and criterion-related validity of Hare (2003) Revised Psychopathy Checklist [PCL-R] in a Latin American forensic context. Brazilian male inmates (124) were administered the PCL-R, along with relevant subscales of an inventory of normal personality [Personality Factorial Inventory], an intelligence scale [Standard Progressive Matrices], and a semi-structured interview based in DSM IV. Criminal offence records were obtained from prison files. Several theoretical factorial structures for the PCL-R were tested and compared. A bifactor model with three factors, one general factor reflecting the overlap across all items, and two independent subfactors reflecting the unique covariation among particular groups of items, shows the better fit. Overall scores on the PCL-R correlated with the number of criminal offenses committed by participants. No significant correlations were found between PCL-R scores and personality or intelligence measures. It was concluded that the PCL-R is a reliable and valid instrument for the assessment of psychopathy in the Brazilian male forensic population. 相似文献

A recent number of studies have focused on the relations between psychosocial factors and sleep disturbances. Like other work-related stressors, workplace byllying is associated with several negative consequences. However, few studies have investigated the influence of workplace byllying on disturbed sleep. Insomnia is the most frequent sleep complaint. Several models have highlighted the importance of cognitive factors in the development and maintenance of insomnia. Cognitive styles such as psychological detachment and rumination may be relevant in this process. The aim of the present study is to examine the moderating role of psychological detachment and rumination on the relationship between workplace byllying and insomnia. To minimize the effect of common method variance, we tested our hypothesis using a research design in which we collected data at two points in time separated by 1 month. A total of 523 individuals responded to both phases, with 511 useable surveys. The results of the hierarchical multiple regression analysis provide evidence for the moderating role of psychological detachment and rumination in the workplace byllying process. Thus, these findings are in line with the cognitive models of insomnia. 相似文献

The purpose of this study was to examine the role of several personality variables (empathy, comprehensibility, challenge and sense of humour) as moderators of the relationship of job demands (traumatic task and overload) with secondary traumatic stress. 175 emergency professionals of the Community of Madrid completed the Secondary Traumatic Stress Measure (STSM). The results of the hierarchical multiple regression analysis provide evidence for the moderator role of personality variables in the secondary traumatic stress process. Lastly, the discussion emphasises the need to focus on the interaction between personality and job demand variables in order to advance our understanding of the process of trauma in emergency professionals. 相似文献

Autophosphorylation of alphaCaMKII is differentially involved in new learning and unlearning mechanisms of memory extinction 下载免费PDF全文
Accumulating evidence indicates the key role of alpha-calcium/calmodulin-dependent protein kinase II (alphaCaMKII) in synaptic plasticity and learning, but it remains unclear how this kinase participates in the processing of memory extinction. Here, we investigated the mechanism by which alphaCaMKII may mediate extinction by using heterozygous knock-in mice with a targeted T286A mutation that prevents the autophosphorylation of this kinase (alphaCaMKII(T286A+/-)). Remarkably, partial reduction of alphaCaMKII function due to the T286A(+/-) mutation prevented the development of extinction without interfering with initial hippocampus-dependent memory formation as assessed by contextual fear conditioning and the Morris water maze. It is hypothesized that the mechanism of extinction may differ depending on the interval at which extinction training is started, being more akin to "new learning" at longer intervals and "unlearning" or "erasure" at shorter intervals. Consistent with this hypothesis, we found that extinction conducted 24 h, but not 15 min, after contextual fear training showed spontaneous recovery (reappearance of extinguished freezing responses) 21 d following the extinction, representing behavioral evidence for new learning and unlearning mechanisms underlying extinction 24 h and 15 min post-training, respectively. Importantly, the alphaCaMKII(T286A+/-) mutation blocked new learning of contextual fear memory extinction, whereas it did not interfere with unlearning processes. Our results demonstrate a genetic dissociation of new learning and unlearning mechanisms of extinction, and suggest that alphaCaMKII is responsible for extinguishing memories specifically through new learning mechanisms. 相似文献

The aim of the present study was to evaluate the occurrence of fear sensitization in rats previously treated with an inhibitor of the NO syntheses and submitted to Trial1/Trial2 plus-maze (PM) procedure. Male Wistar rats received a systemic treatment with N(omega)-nitro-L-Arginine-methyl ester (L-NAME; 5, 10 or 50 mg kg(-1)) and were submitted to PM Trial1. In the following day the animals were re-exposed to the PM with no drug administration (Trial2). Some standards spatial-temporal measures, such as the percentage of entries (% Open arm entries) and time spent (% Open arm time) in the open arms and risk assessment frequency were recorded and used to estimate the animal level of fear sensitization in PM Trial2. The results showed that animals receiving L-NAME (50 mg kg(-1)) displayed increased % Open arm entries and % Open arm time in Trial2 in relation to the group receiving 0.9% saline, which is compatible with impaired fear/anxiety acquisition during Trial1/Trial2 PM procedure. In addition, rats treated with L-NAME (50 mg kg(-1)) exhibited low level of risk assessment in Trial2 in relation to the group treated with 0.9% saline, which indicates low level of fear/anxiety during PM re-exposure. The number of entries into the enclosed arms was not changed by any L-NAME treatment, which suggests no bias of the drug treatments on animal locomotor activity. The data suggest that NO synthesis may mediate the fear sensitization process in the PM. 相似文献

The contribution of past experiences to concurrent resurgence was investigated in three experiments. In Experiment 1, resurgence was related to the length of reinforcement history as well as the reinforcement schedule that previously maintained responding. Specifically, more resurgence occurred when key pecks had been reinforced on a variable-interval 1-min schedule than a variable-interval 6-min schedule, but this effect may have been due either to the differential reinforcement rates or differential response rates under the two schedules. When reinforcement rates were similar (Experiment 2), there was more resurgence of high-rate than low-rate responding. When response rates were similar (Experiment 3), resurgence was not related systematically to prior reinforcement rates. Taken together, these three experimental tests of concurrent resurgence illustrate that prior response rates are better predictors of resurgence than are prior reinforcement rates. 相似文献

Based on Bronfenbrenner's (1999) ecological perspective, a longitudinal, prospective model of individual differences in the quality of home environment (Home Observation for Measurement of the Environment—HOME) was tested in a sample of 179 Brazilian children and their families. Perinatal measures of family socioeconomic status (SES) and child birth weight had direct effects on HOME at preschool age. As either family SES or child birth weight increased, HOME also increased through diminished emotional distress in the mother a month following childbirth. SES had a negative effect on number of children in the household, which in turn had a long-term negative impact on HOME. Compared to mothers who had reported not to plan their pregnancy, those who did were more likely to have fewer children, to report more spouse support during childbearing, and to show less emotional distress a month after childbirth, all of which also influenced HOME at preschool age. These findings are discussed in light of the broader socio-ecological Brazilian context, with direct implications to clinical practice aimed at improving the quality of home environment. 相似文献

This study describes the validity and reliability evidence of the multidimensional measure of employability (MME) based on the internal structure and relations to career self-efficacy and career success. Two hundred forty seven Portuguese persons (75.7% women) aged from 21–73 years old (M = 39.9, SD = 10.9) participated. Confirmatory factor analysis suggested adequate fit in the correlational and hierarchical models. Measurement reliability was good for total score and each factor. Correlations with the additional measures provided evidence of validity. MME provides a tool for research and career counseling, enabling comprehensive employability assessment and personalized interventions, while recognising the interplay between employability dimensions. 相似文献
