This research was conducted to assess the impact of a parent-based verbal responsive intervention, aiming to enhance parents’ responsiveness and communication strategies, by way of a sample of parents and their preschool-aged children with a clinical level of externalizing behavior problems. Twenty-one parents received the intervention, consisting of eight 1.5-hour sessions. The study tested the hypothesis that the intervention led to an improvement in parenting variables and a decrease in children’s behavior problems, assessed by a multimethod procedure. The results partially confirmed the prediction, as they showed an enhancement of parents’ responsiveness and parent self-efficacy belief, which are promising findings, but no modifications of negative practices. These effects persisted for 4 months after the intervention. Moreover, a decrease in children’s externalizing behavior problems was reported by parents in a questionnaire, but this was not confirmed by an observational paradigm. This last result seems to show that a parent-implemented verbal responsive intervention is necessary for some children with externalizing behavior difficulties but often insufficient, and has to be part of a multidisciplinary treatment approach. 相似文献

Past literature on the automaticity of social behavior indicates that priming a concept automatically activates related behavioral schemas. In the two present studies we examined the impact of religion on prosociality. In the first study, we tested the impact of subliminal priming of religious concepts on prosocial behavior intentions. We found a main effect of this priming, moderated by valence: prosocial behavior tendencies were stronger when positive religious words had previously been subliminally primed. In the second study, we examined the accessibility of prosocial concepts, after the supraliminal activation of religion. Indeed, we found that not only were religion‐related attributes more accessible when primed, but positive religious primes were also able to activate prosocial concepts. While previous research has shown the religion‐prosociality link at the explicit level and in terms of the role of individual religiousness, these results indicate that religious concepts by themselves can nonconsciously activate prosocial behavioral schemas.

Monoamine oxidase A (MAO A) degrades serotonin, dopamine and noradrenaline, factors critically involved in the regulation of aggression. Different kinds of aggression were investigated in Tg8, a transgenic mouse strain lacking a functional MAO A gene. MAO A-deficient mice differ from wild-type C3H/HeJ (C3H) in terms of showing higher territorial, predatory and isolation-induced aggression. Tg8 demonstrated shorter latencies to cricket killing and to the first attack after 6 weeks isolation than C3H mice. In the resident-intruder paradigm, MAO A-lacking mice were more aggressive than C3H when tested as intruders. In contrast to C3H, attack in Tg8 mice did not depend on different aggressiveness of intruders of BALB/c, A/Sn and C3H strains. Tg8 mice displayed no increase in aggression but demonstrated reduced social investigation towards anesthetized, as well as towards juvenile BALB/c males. Thus, MAO A deficiency in Tg8 mice is accompanied by increased expression of different kinds of aggression, as well as by disruption of normal pattern of social interaction. 相似文献

Cognitive decline and human (Homo sapiens) aging: an investigation using a comparative neuropsychological approach 总被引:1,自引:0,他引:1

Using a comparative neuropsychological approach, the authors compared performance of younger and healthy older adults ages 65 and over on tasks originally developed to measure cognition in animals. A battery of 6 tasks was used to evaluate object discrimination, egocentric spatial abilities, visual and spatial working memory, and response shifting. Older adults performed more poorly than younger adults on tasks that evaluate egocentric spatial abilities, response shifting, and to a lesser extent object recognition. The two groups did not differ for tasks that evaluate spatial working memory and object discrimination. The impairments the authors observed in tasks that evaluate response shifting and object recognition are consistent with those found in canines and primates as well as those found in Alzheimer's disease. The results are consistent with the notion that cognitive processes supported by the amygdala and the orbitofrontal cortex are among the first to decline with increasing age in both humans and animals. 相似文献

The authors examined reasoning following the terrorist attacks carried out in London in July 2005. They tested participants in London (United Kingdom), Manchester (United Kingdom), and London (Canada) within 1 week of the attacks and again 6 months later. Participants reasoned about syllogisms of 3 types: neutral, generally emotional, and emotionally related to terrorism. Participants also provided self-reports of emotion and risk estimates. Participants generally reasoned more accurately on neutral problems, compared with generally emotional and terrorism-related problems. However, participants in London (United Kingdom) provided more logically valid answers when reasoning about problems related to terrorism and were less likely to answer on the basis of beliefs, despite reporting higher levels of emotions. 相似文献

In 3 experiments, we investigate how anxiety influences interpretation of ambiguous facial expressions of emotion. Specifically, we examine whether anxiety modulates the effect of contextual cues on interpretation. Participants saw ambiguous facial expressions. Simultaneously, positive or negative contextual information appeared on the screen. Participants judged whether each expression was positive or negative. We examined the impact of verbal and visual contextual cues on participants' judgements. We used 3 different anxiety induction procedures and measured levels of trait anxiety (Experiment 2). Results showed that high state anxiety resulted in greater use of contextual information in the interpretation of the facial expressions. Trait anxiety was associated with mood-congruent effects on interpretation, but not greater use of contextual information. 相似文献

Threat detection is an important skill for police officers, but few studies have examined the impact of processing strategies on this ability. The first aim of our study was to compare the visual detection of threatening and neutral targets in 38 police trainees and 53 police officers. The other aims were to examine the effect of emotional or semantic strategies on this process and the effect of psychopathological symptoms. In a visual search task, participants had to detect a threatening or neutral target among neutral distractors. Participants answered a question used to induce a more emotional or semantic processing strategy. Results revealed that threatening targets were detected faster than neutral ones. This effect was enhanced with an emotional processing strategy but unaffected by symptoms. Processing strategy also had led to faster reaction time overall. This study shows that inducing processing strategies can influence threat detection in police trainees and officers. 相似文献

This paper investigates the learnability by positive examples in the sense of Gold of Pregroup Grammars. In a first part, Pregroup Grammars are presented and a new parsing strategy is proposed. Then, theoretical learnability and non-learnability results for subclasses of Pregroup Grammars are proved. In the last two parts, we focus on learning Pregroup Grammars from a special kind of input called feature-tagged examples. A learning algorithm based on the parsing strategy presented in the first part is given. Its validity is proved and its properties are examplified. 相似文献

Objective: The diagnosis of a life-threatening illness can trigger end-of-life fears. Early studies show that end-of-life fears play an important role in chronic obstructive pulmonary disease (COPD). However, predictors of these fears have not yet been identified. This study investigated the relevance of socio-demographic variables, illness severity, psychological distress and disease-specific anxieties as predictors of end-of-life fears in COPD.Design: A total of 131 COPD patients participated at two time points. Regression and mediation analyses, as well as cross-lagged panel analyses were conducted.Main outcome measures: The participants completed questionnaires assessing end-of-life fears (Multidimensional Orientation toward Dying and Death Inventory), psychological distress (Hospital Anxiety and Depression Scale), and disease-specific anxieties (COPD Anxiety Questionnaire). Pulmonary function and a 6-min walk test served as measures of illness severity.Results: Illness severity was not predictive of end-of-life fears. However, gender and psychological distress explained incremental variance. When disease-specific anxieties were included as additional predictors, psychological distress was no longer significant. Cross-lagged panel analyses mostly supported these results. Moreover, disease-specific anxieties mediated the association between psychological distress and end-of-life fears.Conclusion: Administration and intensity of end-of-life care (especially concerning end-of-life fears) in COPD patients should be based not only on illness severity, but rather on psychological distress and disease-specific anxieties. 相似文献
