This paper proposes a developmental framework for disaster studies with children that allows researchers to explore the interaction between developmental change (defined as change that is extended, self-regulated, qualitative, and progressive) and cataclysmic change. It outlines three levels of analysis related to disasters: 1) observing the harm of disasters in the context of age-related changes in children, 2) demonstrating how children are restored to age-typical developmental trajectories following disasters, and 3) investigating how specific disaster experiences are integrated over time with children's ongoing developmental processes, such as their understanding of self and their views of the world. The paper identifies existing studies at each level of the framework, outlines how these levels of analysis can be used in constructing developmental models of disaster response, and offers suggestions for expanding disaster research into additional developmental areas. 相似文献

Prior research has established positive outcomes of health optimism (appraising one's health as good despite poor objective health (OH)) and negative outcomes of health pessimism (appraising health as poor despite good OH), yet little is known about their contributors. We examined the role of psychosocial factors (life event stress, depression, dispositional optimism, perceived social support) in health realism (appraising health in accordance with OH), optimism and pessimism among 489 older men and women. We then accounted for the psychosocial factors when examining multiple health correlates of health realism, optimism and pessimism. Controlling for age, gender and income, regression results indicate that depression and social support were associated with less health optimism, while dispositional optimism was associated with greater health optimism among those in poor OH. Dispositional optimism was associated with less health pessimism and life event stress was associated with greater pessimism among those in good OH. Beyond the effects of the psychosocial factors, structural equation model results indicate that health optimism was positively associated with healthy behaviours and perceived control over one's health; health pessimism was associated with poorer perceived health care management. Health optimism and pessimism have different psychosocial contributors and health correlates, validating the health congruence approach to later life well-being, health and survival. 相似文献

In a sample (n = 235) of 30-, 42-, and 54-month-olds, the relations among parenting, effortful control (EC), impulsivity, and children's committed compliance were examined. Parenting was assessed with mothers' observed sensitivity and warmth; EC was measured by mothers' and caregivers' reports, as well as a behavioral task; impulsivity was assessed by mothers' and caregivers' reports; and committed compliance was observed during a cleanup and prohibition task, as well as measured by adults' reports. Using path modeling, there was evidence that 30-month parenting predicted high EC and low impulsivity a year later when the stability of the outcomes was controlled, and there was evidence that 30- and 42-month EC, but not impulsivity, predicted higher committed compliance a year later, controlling for earlier levels of the outcomes. Moreover, 42-month EC predicted low impulsivity a year later. Fixed effects models, which are not biased by omitted time-invariant variables, also were conducted and showed that 30-month parenting still predicted EC a year later, and 42-month EC predicted later low impulsivity. Findings are discussed in terms of the importance of differentiating between effortful control and impulsivity and the potential mediating role of EC in the relations between parenting and children's committed compliance. 相似文献

We evaluated the effects of monitoring responses on the acquisition of sight words with 3 children with autism. In the training condition, we taught participants a vocal imitation and matching response related to a peer's reading response. In another condition, participants were exposed only to a peer's reading responses. Participants read the words more accurately during test sessions when the monitoring response was required. Results and discussion highlight the importance of identifying component responses of observational learning and the need for additional research in this area. 相似文献

Adolescence is a period of heightened susceptibility to anxiety disorders, yet we have little experimental evidence on what factors may lead to psychopathology in adolescence. Preclinical models of extinction are commonly used to study the treatment of anxiety symptoms. Interestingly, recent research has shown that there are fundamental changes in the process of extinction across development, which may have implications for our understanding of psychopathology across the lifespan. Specifically, this research shows that the process of extinction parallels the nonlinear function of prefrontal cortex development, such that extinction behaviour is similar in juvenile and adult rats, but involves different processes in infancy and adolescence (periods of rapid growth and pruning, respectively). Our previous studies have shown that early-life stress accelerates the transition between infant and juvenile extinction systems. In the current series of experiments, we examined whether the same early-life stress, maternal separation (MS), would lead to an earlier transition between the juvenile and adolescent extinction systems, and between the adolescent and adult extinction systems. We show that MS adolescent rats exhibit more adult-like extinction behaviour, and that adolescent-like extinction emerges earlier in development (i.e. in pre-adolescent rats). These results may have important implications for the understanding and treatment of anxiety symptoms in adolescent populations. 相似文献

The criminal and personality profile of patients with schizophrenia and comorbid psychopathic traits 总被引:1,自引:0,他引:1
Sixty-one male forensic patients who met the DSM-IV criteria for schizophrenia were categorised into high and low psychopathic trait groups using the Psychopathy Checklist: Screening Version. The groups were compared on their criminal history, symptom profile, personality style, risk scores and subsequent institutional violence. Patients with high scores on the PCL:SV had a greater number of previous convictions and were more likely to have a family history of criminality. The high psychopathy-scoring group had higher levels of Positive and Negative Syndrome Scale grandiose and hostile symptomatology, and higher scores on trait impulsivity and aggression. They also had a more coercive, less compliant interpersonal style than the low-psychopathy scoring group. The high-psychopathy scoring group were more likely to be involved in institutional aggression and had higher levels of risk for violence. Patients with schizophrenia and high levels of comorbid psychopathy have a distinctive interpersonal style that may contribute to their greater risk of disruptive institutional behaviour. 相似文献

The associations between children's behavior and their performance on a task with a steadily increasing ratio of punished to rewarded responses was investigated in a group of clinic-referred (n= 92) and normal control (n= 40) children between the ages of 6 and 13. Clinic-referred children with an anxiety disorder played significantly fewer trials than clinic-referred children without an anxiety disorder but the response style of the anxious children did not differ from that of a normal control group. Children with severe conduct problems who had no anxiety disorder played more trials than (a) children with severe conduct problems and a comorbid anxiety disorder, (b) nonanxious children with attention-deficit hyperactivity disorder, and (c) children in the normal control group. The strongest evidence for the reward dominant response style was for nonanxious subjects with elevations on a measure of psychopathic features, irrespective of whether they also had conduct problems and irrespective of whether they were clinic-referred.

Generalization across three stimulus parameters was examined for 5 individuals whose self-injurious behavior was maintained by escape from task demands. Prior to treatment, three stimulus parameters (therapist, setting, and demands) were systematically varied across baseline sessions. These variables were held constant during treatment, which consisted of escape extinction. When treatment was completed, three novel stimulus parameters were probed. If the rate of self-injury was high during this probe, treatment was reimplemented with one new stimulus parameter (the other two were the same as in the original treatment condition). Following this second treatment, another probe with three novel stimuli was conducted. If the rate of self-injury was again high, treatment was implemented again while a second stimulus parameter was changed. This sequence continued until generalization was observed across the three parameters. Results showed idiosyncratic differences in generalization. The behavior of 2 subjects showed complete generalization during the first novel probe. A 3rd subject's behavior showed generalization following treatment across two stimulus parameters (setting and therapist). The behavior of the 2 remaining subjects showed a complete lack of generalization across the three parameters; both subjects required training for novelty by randomly varying the stimulus parameters for a substantial number of sessions. 相似文献

Hand mouthing often has been described as a stereotypic response that is maintained by non-social (automatic) reinforcement; however, data supporting this conclusion can be found in relatively few studies. This series of studies presents an experimental analysis of conditions associated with the maintenance of hand mouthing. In Experiment 1, a functional analysis was conducted for 12 individuals who engaged in chronic hand mouthing to determine whether the behavior is usually maintained independent of social contingencies. Results obtained for 10 subjects were consistent with an automatic reinforcement hypothesis; the remaining 2 subjects' hand mouthing was maintained by social-positive reinforcement. Based on these results, Experiment 2 was designed to identify the specific reinforcing properties of hand mouthing. Each of 4 subjects was provided with a toy that substituted for hand mouthing, and preference for a specific topography of toy manipulation (hand-toy contact or mouth-toy contact) was measured. Results indicated that hand stimulation was the predominant reinforcer for all subjects. Experiment 3 provided an extension of Experiment 2 in that the same responses were measured across a variety of toys presented to each of 5 subjects. Results again indicated that hand stimulation was the predominant reinforcer for all subjects. Implications of these results are discussed with relevance to treatment. 相似文献
