Two studies were conducted to examine gymnasts' memory capabilities in relation to skill level (high and low) and age level (6–8 years and 14–16 years). The first experiment consisted of two trials performed 7 days apart. In the first trial, gymnasts were briefly exposed to a twelve‐element floor routine, and were then required to perform the routine in the same serial order. One week later they were again briefly presented the same sequence, but with the fifth and seventh elements missing. The task was to perform the sequence in order, including the missing elements. The second study involved three trials that were conducted on the same day. A ten‐element sequence was briefly presented on the first trial followed by an immediate test of that sequence. One hour later, participants were asked to perform the sequence again (delayed test). An hour following that, the sequence was again presented with two elements missing. The sequence had to be performed with the missing elements. The results indicate that serial position accuracy of a gymnastic floor routine improves with both age and experience, and that the older experienced gymnasts outperformed all the other gymnasts on all phases of the experiments. These results are interpreted within the Ericsson and Kintsch (1995) theory of Long‐term Working Memory. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

When two targets are presented within approximately 500 ms of each other in the context of rapid serial visual presentation (RSVP), participants’ ability to report the second target is reduced compared to when the targets are presented further apart in time. This phenomenon is known as the attentional blink (AB). The AB is increased in magnitude when the first target is emotionally arousing. Emotionally arousing stimuli can also capture attention and create an AB-like effect even when these stimuli are presented as to-be-ignored distractor items in a single-target RSVP task. This phenomenon is known as emotion-induced blindness (EIB). The phenomenological similarity in the behavioral results associated with the AB with an emotional T1 and EIB suggest that these effects may result from similar underlying mechanisms – a hypothesis that we tested using event-related electrical brain potentials (ERPs). Behavioral results replicated those reported previously, demonstrating an enhanced AB following an emotionally arousing target and a clear EIB effect. In both paradigms highly arousing taboo/sexual words resulted in an increased early posterior negativity (EPN) component that has been suggested to represent early semantic activation and selection for further processing in working memory. In both paradigms taboo/sexual words also produced an increased late positive potential (LPP) component that has been suggested to represent consolidation of a stimulus in working memory. Therefore, ERP results provide evidence that the EIB and emotion-enhanced AB effects share a common underlying mechanism.  相似文献

Emotion perception deficits could be due to disrupted connectivity of key nodes in the salience and emotion network (SEN), including the amygdala, subgenual anterior cingulate cortex (sgACC), and insula. We examined SEN resting-state (rs-)fMRI connectivity in rMDD in relation to Facial Emotion Perception Test (FEPT) performance. Fifty-two medication-free people ages 18 to 23 years participated. Twenty-seven had major depressive disorder (MDD) in remission (rMDD, 10 males), as MDD is associated with emotion perception deficits and alterations in rsfMRI. Twenty-five healthy controls (10 males) also participated. Participants completed the FEPT during fMRI, in addition to an 8-minute eyes-open resting-state scan. Seed regions of interest were defined in the amygdala, anterior insula and sgACC. Multiple regression analyses co-varied diagnostic group, sex and movement parameters. Emotion perception accuracy was positively associated with connectivity between amygdala seeds and regions primarily in the SEN and cognitive control network (CCN), and also the default mode network (DMN). Accuracy was also positively associated with connectivity between the sgACC seeds and other SEN regions, and the DMN, particularly for the right sgACC. Connectivity negatively associated with emotion perception was mostly with regions outside of these three networks, other than the left insula and part of the DMN. This study is the first to our knowledge to demonstrate relationships between facial emotion processing and resting-state connectivity with SEN nodes and between SEN nodes and regions located within other neural networks.  相似文献

Involuntary musical imagery (INMI), i.e the internal experience of a repetitive musical fragment, is one of the most ubiquitous forms of spontaneous cognition. Findings regarding the relationship between INMI and cognitive load are conflicting. In the present study, 200 participants watched and evaluated two non-dialogue, music-only film trailers. Subsequently, they either closed their eyes for 5 min (baseline), or engaged in one of three dot tasks of varying challenge and attentional demand (low, medium, and high cognitive load). Finally, they completed a novel “Mind Activity Questionnaire”, which allows for indirect INMI sampling rather than direct questioning. The same questionnaire was completed 24 hours later. Overall, a significant negative linear trend was found. At baseline, 65% of people reported experiencing INMI. This rate decreased to 32.5% in the low load condition with further reductions observed in the medium and high conditions, which did not differ significantly from each other. INMI frequency and duration followed the same pattern as the induction rates. In the 24-hour follow-up, 21% of participants reported INMI experiences. This study supports the hypothesis that INMI occurrence, frequency, and duration relate to spare cognitive capacity and demonstrates an ecologically valid laboratory paradigm for covertly inducing and documenting INMI experiences.  相似文献

People make movements in a variety of directions when interacting with the world around them. It has been well documented that attention shifts to the goal of an upcoming movement, whether the movement is a saccade or a reach. However, recent evidence suggests that the direction of a movement may influence the spatial spread of attention (Stewart & Ma-Wyatt, 2015, Journal of Vision, 15(5), 10). We investigated whether the spatiotemporal profile of attention differs depending on where that location is situated relative to the direction of movement, and if this pattern is consistent across different movement effectors. We compared attentional facilitation at locations in line with or orthogonal to the movement, for reach-only, reach-plus-saccade, and saccade-only conditions. Results show that the spatiotemporal profile of attention differs across different movement combinations, and is also different at target locations orthogonal to and in line with the movement direction. Specifically, when a reach alone was made, there was a general decrease in attention at all locations during the movement and a general increase in attention at all locations with a saccade only. However, the concurrent reach and saccade condition showed a premovement attentional facilitation at locations orthogonal to movement direction, but not those in line with the movement direction. These results suggest attentional guidance may be more important at differing time points, depending on the type of movement.  相似文献

Martin Luther's social writings (volumes 44–47 in the American edition) provide a robust account of human agency that might help Lutheran social ethics address contemporary crises of confidence. When Luther addresses concrete moral issues, he enriches his two‐kingdoms frame with a focus on particular social roles such as ruler, merchant, soldier, parent, etc. This (often tacit) “three‐estates” approach creates room for a distinctly Lutheran contribution to contemporary virtue theory by focusing on the functions served by particular social roles more than on individual self‐chosen pathways of moral improvement. It also supports a prophetic affirmation of vocation against the contemporary breakdown of expectations and confidence in social roles.  相似文献

Responding to stimuli as same and different can be considered a critical component of a variety of language and academic repertoires. Whereas responding to “sameness” and generalized identity matching (i.e., coordination) have been studied extensively, there appears to be a significant gap in behavior analytic research and educational programs with regard to nonmatching relations or relations of difference. We review research on difference relations from a variety of domains, including comparative psychology, as well as experimental, and translational behavior analysis. We examine a range of studies, including research on the perception of difference and oddity responding, as well as investigations on establishing relational frames of distinction. We present suggestions for future research and describe potential methods for teaching skills related to relations of difference.  相似文献

Gratitude has been promoted as a beneficial emotional experience. However, gratitude is not universally experienced as positive. The current work examines whether an autonomous interpersonal style is associated with differential experience of gratitude. Study 1 found an inverse relationship between trait autonomy and both trait gratitude and positivity of response to receiving a hypothetical benefit from a friend. Study 2 replicated the finding that those higher in autonomy report less trait gratitude, and also demonstrated an inverse relationship between autonomy and valuing gratitude. Study 3 found that those higher in autonomy had more self-image goals and reduced compassionate goals in relationships, and that valuing gratitude mediated the relationship between autonomy and relationship goals. These results show a consistent inverse relationship between autonomy and the experience and valuing of gratitude, suggesting that degree of autonomy is one determinant of whether gratitude is experienced as positive.  相似文献

Asthma remains the most prevalent chronic illness among children. Despite the substantial body of literature examining children with asthma, few studies have examined parents’ perspectives of the condition and experiences of caregiver stress. Parents of children with chronic illnesses experience elevated stress and may have limited opportunities to cope with complex emotions while caring for children with asthma. Drawing from focus groups and interviews with African American and Hispanic parents of children with asthma, this qualitative study was conducted as part of a patient-centered engagement process to inform the refinement of an intervention aimed at reducing stress among parents of children with asthma. All data were transcribed and underwent three waves of inductive analysis. The content analysis indicated that the unpredictable nature of asthma and the caregiving burden associated with managing children’s asthma contributed to parents’ stress, and external contexts compounded the impact of these stressors. Parents also reported having difficulty identifying how they coped with stress and employed approaches to coping with stress that they applied intermittently but encountered several barriers to enacting known or available coping strategies. Analyses also revealed that parents desired a multimodal stress reduction intervention that emphasized building relationships, allowed for flexibility, and encouraged staff-parent communication. Whereas African American and Hispanic parents’ experiences of stress and coping strategies were similar, their preferences differed in regards to incorporating technology into the intervention, the credentials of facilitators, and the salience of language preferences. Understanding the complexities of stressors facing caregivers is important for developing interventions to support parents and children coping with asthma, and in particular when working with families from diverse backgrounds.  相似文献

The aim of this study was to examine possible links between different lifestyle patterns and aberrant driver’s behaviour. Personal interviews were conducted in a representative sample of 324 adults (18–65), all residents of Crete. Aberrant driver’s behaviour was assessed by the ‘driver behaviour questionnaire’ (DBQ). Also to measure different dimensions of lifestyle, first, a 26-items questionnaire was used, and second, three questions measuring ‘driving without destination’, related in previous findings with road accident risk. Four lifestyle patterns: ‘religion/tradition’, ‘driving aimlessly’, ‘sports’ and ‘culture’ are significant predictors of ordinary violations. ‘Driving without destination’ has a significant effect all three DBQ factors (b positive). ‘Religion/tradition’ was related only to ordinary violations (b negative) and ‘sports’ has a positive impact on ordinary violations and a negative impact on ‘errors’. Two lifestyle factors are related to more dangerous driving: ‘Driving without destination’ and/or pursuing a more ‘athletic way of living’. Road safety campaigns must teach the first group to use other hobbies and activities to vent their feelings and the second, not to overestimate their abilities, while driving.  相似文献
