In this article, we combine two analogue experiments in which we empirically examined three malingering methodological issues in individuals trained and instructed to simulate posttraumatic stress disorder (PTSD) on the Trauma Symptom Inventory (TSI; Briere, 1995). In Experiment 1, we examined TSI scale effects of the following manipulations using a 2 x 2 design with 330 college students: (a) inclusion or exclusion of cautionary instructions regarding believability of participants' simulation and (b) different financial incentive levels. In Experiment 2, we examined comorbid psychiatric diagnostic training with 180 college students who were either trained to simulate PTSD and comorbid major depressive disorder or trained to simulate only PTSD. Caution main effects were significant for all but two TSI Clinical Scales, incentive main effects and interactions were only significant for one Clinical scale each, and the comorbidity manipulation did not yield any scale differences. We discuss malingering research design implications regarding the use of cautionary instructions, financial incentive levels, and comorbid training. 相似文献

Two studies examined how non-interpersonal forgiveness (when there is no social relationship between the transgressor and forgiver) related to coping and involuntary responses to stress, psychological distress, and religiosity. Three to six weeks after September 11th, 2001, forgiveness had non-linear associations with other responses to the terrorist attacks. Among college students (N=488), those who were trying or had forgiven (pro-forgiveness) the terrorists reported less involuntary engagement, more primary and secondary control coping, and more meaning finding than those who were unsure about forgiveness (ambivalent) and those who did not believe the perpetrators should be forgiven (anti-forgiveness). Ambivalent students reported the most distress, even after controlling for religion. Anti-forgiveness students reported less religiosity than ambivalent and pro-forgiveness students. Most findings were consistent among middle schoolers (N=154), particularly regarding psychological distress and responses to stress. Also, forgiveness of strangers for acts against one's community functioned separately from religion. 相似文献

Stress administered prior to encoding impairs neutral but enhances emotional long-term episodic memories 下载免费PDF全文

Stressful events frequently comprise both neutral and emotionally arousing information, yet the impact of stress on emotional and neutral events is still not fully understood. The hippocampus and frontal cortex have dense concentrations of receptors for stress hormones, such as cortisol, which at high levels can impair performance on hippocampally dependent memory tasks. Yet, the same stress hormones can facilitate memory for emotional information, which involves interactions between the hippocampus and amygdala. Here, we induced psychosocial stress prior to encoding and examined its long-term effects on memory for emotional and neutral episodes. The stress manipulation disrupted long-term memory for a neutral episode, but facilitated long-term memory for an equivalent emotional episode compared with a control condition. The stress manipulation also increased salivary cortisol, catecholamines as indicated by the presence of alpha-amylase, heart rate, and subjectively reported stress. Stressed subjects reported more false memories than nonstressed control subjects, and these false memories correlated positively with cortisol levels, providing evidence for a relationship between stress and false memory formation. Our results demonstrate that stress, when administered prior to encoding, produces different patterns of long-term remembering for neutral and emotional episodes. These differences likely emerge from differential actions of stress hormones on memory-relevant regions of the brain. 相似文献

This qualitative study explored the views of spouse carers in relation to the emotional impact of caring for a partner with a chronic or terminal illness. The study population consisted of nine full‐time spouse carers, recruited using a snowball sampling strategy. Semi‐structured interviews took place in the carers’ homes. These were recorded and transcribed verbatim. The data were then analysed using constant comparative analysis. Themes identified included the emotional and physical health of the carer, personality changes in the spouse, relationship issues, denial, anticipating death, accessing support and coping strategies. Findings indicate that these carers experienced a whole range of feelings and emotions, which impacted on their health and well‐being. They included fatigue, stress, distress, anxiety, depression, feelings of isolation and suicidal thoughts. These were particularly profound around the time of diagnosis, end of treatment, during a relapse and most particularly around the time of death. An increasing number of terminally ill people are now expressing a preference to be cared for at home. The potential risks to the health of caregivers therefore need to be taken into account. This study highlights the importance of assessing the needs of carers in order to identify those at risk of compromised health, which would then allow those requiring support to be offered prompt referral to specialist services. 相似文献

Study 1 expands upon previous research by looking at the ability of untrained raters to detect pathological traits within a normal population of college students. In Study 1, 30-s video clips of 81 target persons were shown to 42 raters. Ratings of traits of personality disorders made by thin slice raters reliably predicted scores on the personality pathology measures obtained from the targets themselves and from close peers. Study 2 is a preliminary examination of how pathological rater traits impacts thin slice accuracy. In Study 2, peer and self-report data were examined regarding 87 thin slice raters. Raters who exhibited traits of narcissistic personality disorder were significantly less accurate in making personality predictions regarding targets. Three clusters of personality items were identified based on rater characteristics related to accuracy in predicting behavior. 相似文献

This study investigated the effectiveness of functional behavioral assessment (FBA)—informed interventions for sleep problems, particularly co‐sleeping, in children with autism spectrum disorder (ASD). Seven children, who exhibited multiple sleep problems including unwanted co‐sleeping, participated. FBA, based on information derived from interviews and parent‐recorded sleep diaries, was used to develop individualized case formulations upon which multicomponent, parent‐implemented interventions were based. These were evaluated using a single‐case, non‐concurrent multiple‐baseline‐across‐participants design. Improvements were observed across all sleep problems, including the elimination of co‐sleeping. Gains were maintained at follow‐up for five out of seven children, though two children did not complete intervention. Parents reported high levels of satisfaction with the program. FBA‐based interventions for sleep problems in children with ASD and their clinical implications are further discussed. 相似文献

α7 Nicotinic Receptor Subunits Are Not Necessary for Hippocampal-Dependent Learning or Sensorimotor Gating: A Behavioral Characterization of Acra7-Deficient Mice 下载免费PDF全文

The α7 nicotinic acetylcholine receptor (nAChR) subunit is abundantly expressed in the hippocampus and contributes to hippocampal cholinergic synaptic transmission suggesting that it may contribute to learning and memory. There is also evidence for an association between levels of α7 nAChR and in sensorimotor gating impairments. To examine the role of α7 nAChRs in learning and memory and sensorimotor gating, Acra7 homozygous mutant mice and their wild-type littermates were tested in a Pavlovian conditioned fear test, for spatial learning in the Morris water task, and in the prepulse inhibition paradigm. Exploratory activity, motor coordination, and startle habituation were also evaluated. Acra7 mutant mice displayed the same levels of contextual and auditory-cue condition fear as wild-type mice. Similarly, there were no differences in spatial learning performance between mutant and wild-type mice. Finally, Acra7 mutant and wild-type mice displayed similar levels of prepulse inhibition. Other behavioral responses in Acra7 mutant mice were also normal, except for an anxiety-related behavior in the open-field test. The results of this study show that the absence of α7 nAChRs has little impact on normal, base-line behavioral responses. Future studies will examine the contribution of α7 nAChR to the enhancement of learning and sensorimotor gating following nicotine treatments. 相似文献

The impact of mothers' gender-role stereotypic beliefs on mothers' and children's ability perceptions. 总被引:1,自引:0,他引:1
The focus of this study is the relation between mothers' gender stereotypic beliefs, their perceptions of their children's abilities, and their children's self-perceptions in 3 activity domains. Approximately 1,500 mothers and their 11- to 12-year-old children responded to questions about the children's abilities in the math, sports, and social domains. It was predicted that mothers' beliefs about their children would be moderated by their gender stereotypic beliefs about the abilities of female and male people in general. As predicted, path analyses revealed that mothers' gender stereotypic beliefs interact with the sex of their child to influence their perceptions of the child's abilities. Mothers' perceptions, in turn, mediate the influence of past performance on children's self-perceptions in each domain. 相似文献

The present study examined the process of shared leadership in 45 ad hoc decision-making teams. Each team member's leadership behavior (n = 180) was assessed by behaviorally coding videotapes of the teams' discussions. The within-team patterns of leadership behavior were examined using cluster analysis. Results indicated that the likelihood of a team experiencing a full range of leadership behavior increased to the extent that multiple team members shared leadership, and that teams with shared leadership experienced less conflict, greater consensus, and higher intragroup trust and cohesion than teams without shared leadership. This study supports previous findings that shared leadership contributes to overall team functioning, and begins to delineate the extent to which team members may naturally share leadership. 相似文献
