Classical conditioning is one of the most fundamental types of learning, yet demonstrating its principles in a classroom setting can be challenging. This study introduces using PowerPoint as a new, practical technique that can be used in a classroom setting to demonstrate classical conditioning. The PowerPoint file is flexible and easy to adapt for demonstrating various aspects of classical conditioning (including higher order conditioning) in a concrete manner. Moreover, this study was designed to measure salivation in a more objective and valid way which could be used by student researchers interested in measuring salivation as a conditioned response.  相似文献

The study of attentional capture has provided a rich context for assessing the relative influence of top-down and bottom-up factors in visual perception. Some have argued that attentional capture by a salient, irrelevant stimulus is contingent on top-down attentional set (e.g., Folk, Remington, & Johnston, Journal of Experimental Psychology: Human Perception and Performance 18:1030?C1044, 1992). Others, however, have argued that capture is driven entirely by bottom-up salience and that top-down factors influence the postallocation speed of disengagement from the irrelevant stimulus (e.g., Theeuwes, Acta Psychologica 135:77?C99, 2010a). In support of this speed-of-disengagement hypothesis, recent findings from the modified spatial-cuing paradigm show that cues carrying a no-go target property produce reverse, or negative, cuing effects, consistent with inhibition of the cue location from which attention has been very quickly disengaged (Belopolsky, Schreij, & Theeuwes, Perception, & Psychophysics, 72, 326?C341, 2010). Across six experiments, we show that this inhibitory process can be dissociated from shifts of spatial attention and is, thus, not a reliable marker of capture. We conclude that the data are inconsistent with the predictions of the disengagement hypothesis.  相似文献

Institutional rearing negatively impacts the development of children's social skills and executive functions (EF). However, little is known about whether childhood social skills mediate the effects of the foster care intervention (FCG) and foster caregiving quality following early institutional rearing on EF and social skills in adolescence. We examined (a) whether children's social skills at 8 years mediate the impact of the FCG on the development of EF at ages 12 and 16 years, and (b) whether social skills and EF at ages 8 and 12 mediate the relation between caregiving quality in foster care at 42 months and subsequent social skills and EF at age 16. Participants included abandoned children from Romanian institutions, who were randomly assigned to a FCG (n = 68) or care as usual (n = 68), and a never-institutionalized group (n = 135). At ages 8, 12, and 16, social skills were assessed via caregiver and teacher reports and EF were assessed via the Cambridge Neuropsychological Test Automated Battery. Caregiving quality of foster caregivers was observed at 42 months. FCG predicted better social skills at 8 years, which in turn predicted better EF in adolescence. Higher caregiver quality in foster care at 42 months predicted better social skills at 8 and 12 years, and better EF at 12 years, which in turn predicted 16-year EF and social skills. These findings suggest that interventions targeting caregiving quality within foster care home environments may have long-lasting positive effects on children's social skills and EF.  相似文献

Wright's emphasis on and illustration of the use of family therapy research as a unique intervention technique for therapy is an important contribution to the practice literature. Equally important, however, is the isomorphic shift in focus of the family therapy researcher. Rather than focusing only on process or outcome research, family therapists should become more interested in their clients as research subjects. Though rarely discussed in the family therapy literature, the competencies of family therapists as researchers and the utility of research in a family therapy context is critical to being a well-rounded professional. Examples are provided of how this emphasis is being introduced in a PhD family therapy program.  相似文献

Family therapy in Britain must develop to encompass the external reality of family life. Living in a racist society dominates the lives of all black families. Family therapists need to acknowledge and address this before intervening in the family system. This paper offers personal and professional experiences, confrontaion, structured exercises and general and specific principles for work with black families. Minimal and positive goals are advocated so that practitioners do not feel paralysed by the enormity of the task.  相似文献

In the present article, we extend a model of relational spirituality and forgiveness to the context of major offenses by clergy. In Study 1, undergraduate students (N = 208) described a major offense that they had experienced by a religious leader and then completed several questionnaires in relation to the offense and the religious leader. Appraisals of relational spirituality were significantly associated with forgiveness, after controlling for known predictors of forgiveness (i.e., hurtfulness, time since the offense, and commitment to God or another source of spirituality). In Study 2, we replicated and extended the findings from Study 1 using an independent sample of undergraduates (N = 365). In a series of structural equation models, we found that relational engagement of God (or another source of spirituality) partially mediated the relationship between anger toward God (or another source of spirituality) and unforgiving motivations. We conclude by discussing implications for future research.  相似文献

Efforts to discourage excessive alcohol use among young people can only be effective if the target audience is exposed to, attends to, and comprehends key messages. The aim of this study was to examine age and sex differences in drinking motives to better inform development of targeted interventions to reduce alcohol-related harm. Thirty individual interviews and 12 group interviews were conducted with English 13–25?year olds. Interviewees gave multiple motivations for drinking – especially those related to image and reputation, and played down the health implications of heavy drinking. Negative aspects of drinking – caring for drunk friends, being cared for when drunk and suffering through hangovers with friends – were considered to offer opportunities for closer interpersonal bonding than other social activities. Respondents distanced themselves from ‘problem’ drinkers, but disapproved of others’ problematic drinking or antisocial behaviour. Narrative messages demonstrating the social consequences of excessive consumption were preferred to single, static messages emphasising risk or harm. Interviewees noted that interventions must use an engaging tone or pitch: they considered many campaigns to be patronising or preaching. A lack of consensus between age and sex groups highlighted a need for multifaceted, multi-modal approaches that utilise mobile technologies and new media.  相似文献

Abstract

The purpose of this study was to test a mediational model of risk and protective factors associated with the psychological adjustment of caregivers of head-injured patients. Forty-three caregivers of patients who had suffered a head injury participated in the study. Findings strongly supported hypotheses. Caregiver burden was associated with poorer psychological adjustment. Social support and a higher percentage of approach coping strategies relative to overall coping strategies were associated with better psychological adjustment. As predicted, caregiver burden showed a direct relationship to psychological adjustment, while social support showed an indirect relationship to adjustment mediated by percentage approach coping.  相似文献

Equivalent English and German versions of the State-Trait Depression Scales (STDS) were developed and presented to samples of American and German students who were comparable with regard to gender and age. Factorial structure and equivalence of the two versions were determined by confirmatory factor analyses (CFA). The CFAs included multiple group analyses which were employed to compare factor patterns, loadings, factor variances and covariances across the two samples. In addition, statistical and psychometric properties of the items and scales were determined and mean differences between nationalities and genders on these scales were tested. In order to obtain information about the external validity, relationships between the STDS and tests which already exist in English and German (several depression scales as well as the State-Trait Personality Inventory, the State-Trait Anger Expression Inventory, and the Mainz Coping Inventory) were analysed.  相似文献

We functionally defined and tested a model of psychological distress for mothers of children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD). This operationalized model includes three latent constructs which are hypothesized to influence mother's psychological symptomatology: Parenting Stress, Parent Characteristics, and Environment Characteristics. Structural equation modeling was used to reformulate and test the measurement models and the overall model. Data supported a model with some empirically-based model revisions founded on both comparisons of best fit and by an examination of statistical modification indices. The final model maintained the Parenting Stress and Parental Characteristics constructs, but replaced independent environmental variables with a more generalized construct of life stress.  相似文献
