To understand how viewers or readers process and remember media narratives such as entertainment, news, and information is critical to our understanding of the mental processing of television and other media. Media stories contain both typical and atypical events and people, but little is known about how readers or viewers process and remember these two types of information. Participants in 2 experiments remembered atypical story items much better even a week later. However, the conservative way they treated atypical memories could give the illusion that typical items are better remembered than they really are. The results have implications for both mass media theory and theories of memory. 相似文献

In the reported, experiment participants hit a ball to aim at the vertex of a Müller–Lyer configuration. This configuration either remained stable, changed its shaft length or the orientation of the tails during movement execution. A significant illusion bias was observed in all perturbation conditions, but not in the stationary condition. The illusion bias emerged for perturbations shortly after movement onset and for perturbations during execution, the latter of which allowed only a minimum of time for making adjustments (i.e., approx.170 ms). These findings indicate that allocentric information is exploited for online control when people make rapid adjustments in response to a sudden change in the environment and not when people guide their limb movements to interact with a stable environment. 相似文献

The physical disabilities associated with scleroderma are well known but the psychological impact of the condition has received less attention. Few studies have examined appearance related issues, most notably of the face. The aim of this study is to evaluate the psychological impact of facial, aesthetic and functional changes in scleroderma. One hundred seventy-one patients with a clinical diagnosis of scleroderma were recruited into the study. Digital photographs were objectively graded into groups based on severity of disfigurement as judged by an observer. Facial movement was recorded using a modified House-Brackmann Grading Scale. Psychological evaluation comprised the Derriford Appearance Scale short-form (DAS), the Noticeability and Worry score and the Hospital Anxiety and Depression Scale (HADS). Severity of disfigurement predicted decreased mouth opening, the extent to which participants judged their appearance as noticeable to others, and the level of appearance-related concern as measured by the DAS24. There was an inverse relationship with age. Facial changes were ranked as the most worrying aspect of the condition. This study shows facial disfigurement impacts on patient with scleroderma independent of functional changes related to systemic disease. The major difficulty is with the perceived noticeably of the condition to other people and the resulting self-consciousness in social encounters. 相似文献

It is well known that timing of rhythm production is disrupted by delayed auditory feedback (DAF), and that disruption varies with delay length. We tested the hypothesis that disruption depends on the state of the movement trajectory at the onset of DAF. Participants tapped isochronous rhythms at a rate specified by a metronome while hearing DAF (for piano tones) of differing lengths. Motion capture was used to analyze movement trajectories. Mean Inter-Response Intervals (IRIs) varied as an approximately sinusoidal function of feedback condition, with DAF causing slowed production for shorter delays and speeded production for faster delays. Motion capture analyses revealed that finger velocity at the time of DAF predicted the effect of DAF on mean IRI whereas finger position predicted the variability of IRIs. A second experiment in which participants were instructed to vary the timing of peak finger height confirmed that the effect of DAF on timing variability is directly influenced by the finger trajectory. 相似文献

This study was a randomised control trial with a waiting control group. It was designed to evaluate the effectiveness of a 6-month, group-based diabetes prevention programme, The Healthy Living Course and assess whether participation in the programme led to changes in modifiable risk factors for type 2 diabetes among an already at-risk pre-diabetic population. Individuals designated at risk for diabetes by their general practitioners (GPs) were screened using an Oral Glucose Tolerance Test. Volunteers (N = 307) with pre-diabetes were assigned to an intervention or wait-control group in the ratio of approximately 2 : 1. The sample was pre-tested on biochemical, anthropometric and self-report behavioural, cognitive and mood variables and post-tested either at the end of the educational/support-based lifestyle programme or the end of the wait period. The intervention group significantly improved their diabetes knowledge, motivation to change, positive affect, healthy eating and activity levels and showed significantly greater reductions in weight, body mass index, waist circumference, diastolic blood pressure and fasting plasma glucose in comparison with controls. The intervention group also changed their diagnostic status from pre-diabetes to non-diabetes at a greater rate than the wait group (43% vs. 26%) who received standard care from their GPs. 相似文献

Research on resiliency and recovery in forensic psychiatric patients is still limited. Information pertaining to factors associated with successful community reintegration would contribute to a more comprehensive assessment of functioning and informed treatment planning that fits within a recovery approach of service provision. Using a retrospective design involving file reviews and a 3-year follow-up period, the authors investigated the rate of successful/unsuccessful community reintegration (defined by the presence or absence of an absolute discharge/readmission to hospital) in female forensic psychiatric patients (N = 48). The study evaluated the extent to which the risk and protective factors captured in the Short-Term Assessment of Risk and Treatability (START) predicted a range of positive and negative outcomes in the study sample. Results showed that 47.9% of the women qualified as having successfully reintegrated into the community, with the remaining 52.1% qualifying as still being in recovery. Successful individuals possessed significantly more protective factors and significantly fewer risk factors than individuals still in recovery. Furthermore, both the vulnerability and the strength scale of the START demonstrated good predictive validity, however we did not find evidence of incremental validity of the strength scale.

Behavioral inhibition is a temperament characterized in infancy and early childhood by a tendency to withdraw from novel or unfamiliar stimuli. Children exhibiting this disposition, relative to children with other dispositions, are more socially reticent, less likely to initiate interaction with peers, and more likely to develop anxiety over time. Until recently, a dominant model attributed this disposition to reductions in the threshold for engaging the circuitry supporting fear learning, particularly the amygdala. Recent work, however, also has implicated striatal circuitry and other regions that constitute components of a presumed reward system. A series of studies found that behaviorally inhibited adolescents display heightened activation of striatal structures to cues indicating an opportunity to receive reward. This article reviews evidence implicating dual roles for fear and reward circuitry in the expression of behavioral inhibition. 相似文献

A large body of evidence suggests that action execution and action observation share a common representational domain. To date, little is known about age-related changes in these action representations that are assumed to support various abilities such as the prediction of observed actions. The purpose of the present study was to investigate (a) how age affects the ability to predict the time course of observed actions; and (b) whether and to what extent sensorimotor expertise attenuates age-related declines in prediction performance. In a first experiment, older adults predicted the time course of familiar everyday actions less precisely than younger adults. In a second experiment, younger and older figure skating experts as well as age-matched novices were asked to predict the time course of figure skating elements and simple movement exercises. Both young age and sensorimotor expertise had a positive influence on prediction performance of figure skating elements. The expertise-related benefit did not show a transfer to movement exercises. Together, the results suggest a specific decline of action representations in the aging mind. However, extensive sensorimotor experience seems to enable experts to represent actions from their domain of expertise more precisely even in older age. 相似文献
