This study investigates the influence of activating specific motor codes on the comprehension of passages that describe the use of an object requiring similar motor manipulations. In three experiments, participants either imagined or pantomimed performing an action involving a common object. Participants then held the action in memory while reading a brief story, which described another object that required similar or different motor behaviors. Reading times were collected on the complementary actions. Finally, participants acted out the original action. In Exp. 1 and 2, reading slowed to the verbs. Exp. 2 revealed the slowing to be true interference, which disappeared in Exp. 3 when the action did not need to be recalled. The results suggest that readers activate motor codes when reading story actions, which supports an embodied view. The results also indicate that activated codes bound to an action will, at least briefly, impair reading about a complementary action requiring the same codes, consistent with Hommel's (2009) theory of event coding.  相似文献

Cognitive-behavioural models of body dysmorphic disorder (BDD) suggest that mirrors can act as a trigger for individuals with BDD, resulting in a specific mode of cognitive processing, characterised by an increase in self-focussed attention and associated distress. The aim of the current study was to investigate these factors experimentally by exposing participants with BDD (n = 25) and without BDD (n = 25) to a mirror in a controlled setting. An additional aim was to ascertain the role of duration of mirror gazing in the maintenance of distress and self-consciousness by manipulating the length of gazing (short check vs. long gazing). Findings demonstrated that contrary to what was predicted, not only participants with BDD, but also those without BDD experienced an increase in distress and self-focused attention upon exposure to the mirror. In addition, people without BDD, unlike those with BDD, experienced more distress when looking in the mirror for a long period of time as opposed to a short period of time. This lends some support to the idea that, for people with BDD, gazing in a mirror, regardless of duration, might act as an immediate trigger for an abnormal mode of processing and associated distress, and that this association has developed from past excessive mirror gazing. Further theoretical implications of these findings, as well as subsidiary research questions relating to additional cognitive factors are discussed.  相似文献

Binge eating disorder (BED) is a common and under-treated condition with major health implications. Cognitive behavioural therapy (CBT) self-help manuals have proved to be efficient in BED treatment. Increasing evidence also support the use of new technology to improve treatment access and dissemination. This is the first randomised controlled study to evaluate the efficacy of an Internet guided self-help treatment programme, based on CBT, for adults with threshold and subthreshold BED. Seventy-four women were randomised into two groups. The first group received the six-month online programme with a six-month follow-up. The second group was placed in a six-month waiting list before participating in the six-month intervention. Guidance consisted of a regular e-mail contact with a coach during the whole intervention. Binge eating behaviour, drive for thinness, body dissatisfaction and interoceptive awareness significantly improved after the Internet self-help treatment intervention. The number of objective binge episodes, overall eating disorder symptoms score and perceived hunger also decreased. Improvements were maintained at six-month follow-up. Dropouts exhibited more shape concern and a higher drive for thinness. Overall, a transfer of CBT-based self-help techniques to the Internet was well accepted by patients, and showed positive results for eating disorders psychopathology.  相似文献

The purpose of the present study was to compare the effect of cognitive reappraisal and acceptance on subjective distress, physiological reactions and behavioral avoidance in relation to aversive emotional states elicited by film-clips. Ninety-four participants were randomized to one of three groups. The Reappraisal group was instructed to think about what they saw in a way that minimized negative emotional reactions, the Acceptance group was told to let their feelings come and go without trying to control or avoid them, while the Watch (control) group was told just to watch the film-clips. Compared to the control condition, both reappraisal and acceptance led to significant reductions of subjective distress, physiological reactions associated with aversive emotions and behavioral avoidance. On the three types of measures there were few significant differences between the Reappraisal and Acceptance groups, but when such differences existed they were to the benefit of the Reappraisal condition. In the reappraisal condition there was however a positive correlation between elicited aversive emotion and avoidance, while no such correlation existed in the acceptance condition. The results are interpreted and discussed in relation to the theories underlying reappraisal and acceptance as well as the conceptual framework for emotion regulation established by Gross (2007).  相似文献

Objective

Feasibility, acceptability, and efficacy of a Dialectical Behavioral Therapy (DBT) -based method developed in Germany were evaluated in a Swedish outpatient psychiatric context.

Method

Fifty-one adults with ADHD on stable medical treatment or on no medication were randomized to the DBT-based skills training (n = 26) or a parallel loosely structured discussion group (n = 25). Self-rating scales were administered before randomization and after the treatment.

Results

Feasibility and participant satisfaction were good in both groups while skills training was perceived as more logical and effective for ADHD-related problems. The analyses of the individuals who completed the treatment and remained stable with regard to medication (n = 19 in skills training; n = 18 in control group) showed a significant reduction in ADHD symptoms in the skills training group, but not in the control group. No reduction of comorbidity was observed in any of the groups.

Conclusions

The treatment was feasible in an outpatient psychiatric context, well tolerated, and significantly reduced ADHD symptoms in on-treatment individuals who remained stable regarding medication status.  相似文献

Do infants develop meaningful social preferences among novel individuals based on their social group membership? If so, do these social preferences depend on familiarity on any dimension, or on a more specific focus on particular kinds of categorical information? The present experiments use methods that have previously demonstrated infants’ social preferences based on language and accent, and test for infants’ and young children’s social preferences based on race. In Experiment 1, 10-month-old infants took toys equally from own- and other-race individuals. In Experiment 2, 2.5-year-old children gave toys equally to own- and other-race individuals. When shown the same stimuli in Experiment 3, 5-year-old children, in contrast, expressed explicit social preferences for own-race individuals. Social preferences based on race therefore emerge between 2.5 and 5 years of age and do not affect social choices in infancy. These data will be discussed in relation to prior research finding that infants’ social preferences do, however, rely on language: a useful predictor of group or coalition membership in both modern times and humans’ evolutionary past.  相似文献

Research on age-related cognitive change traditionally focuses on either development or aging, where development ends with adulthood and aging begins around 55 years. This approach ignores age-related changes during the 35 years in-between, implying that this period is uninformative. Here we investigated face recognition as an ability that may mature late relative to other abilities. Using data from over 60,000 participants, we traced the ability to learn new faces from pre-adolescence through middle age. In three separate experiments, we show that face learning ability improves until just after age 30 – even though other putatively related abilities (inverted face recognition and name recognition) stop showing age-related improvements years earlier. Our data provide the first behavioral evidence for late maturation of face processing and the dissociation of face recognition from other abilities over time demonstrates that studies on adult age development can provide insight into the organization and development of cognitive systems.  相似文献

Language has been linked to spatial representation and behavior in humans, but the nature of this effect is debated. Here, we test whether simple verbal expressions improve 4-year-old children’s performance in a disoriented search task in a small rectangular room with a single red landmark wall. Disoriented children’s landmark-guided search for a hidden object was dramatically enhanced when the experimenter used certain verbal expressions to designate the landmark during the hiding event. Both a spatial expression (“I’m hiding the sticker at the red/white wall”) and a non-spatial but task-relevant expression (“The red/white wall can help you get the sticker”) enhanced children’s search, relative to uncued controls. By contrast, a verbal expression that drew attention to the landmark in a task-irrelevant manner (“Look at this pretty red/white wall”) produced no such enhancement. These findings provide further evidence that language changes spatial behavior in children and illuminate one mechanism through which language exerts its effect: by helping children understand the relevance of landmarks for encoding locations.  相似文献

Jean Piaget’s theory is a central reference point in the study of logico-mathematical development in children. One of the most famous Piagetian tasks is number conservation. Failures and successes in this task reveal two fundamental stages in children’s thinking and judgment, shifting at approximately 7 years of age from visuospatial intuition to number conservation. In the current study, preschool children (nonconservers, 5-6 years of age) and school-age children (conservers, 9-10 years of age) were presented with Piaget’s conservation-of-number task and monitored by functional magnetic resonance imaging (fMRI). The cognitive change allowing children to access conservation was shown to be related to the neural contribution of a bilateral parietofrontal network involved in numerical and executive functions. These fMRI results highlight how the behavioral and cognitive stages Piaget formulated during the 20th century manifest in the brain with age.  相似文献
