Recent models of schizophrenia suggest deficient use of contextual response cues when confronted with countermanding emotional cues. It is important to clinically validate these models by testing patients diagnosed with schizophrenia on tasks with competing emotional and contextual response determinants. Control and schizophrenia groups completed a novel task that elicited motor responses consistent with, or in opposition to, pre‐potent emotional actions (i.e., approach vs. avoidance). An analogous non‐emotional task was also used to examine cue‐conflict impairment more generally. The groups demonstrated statistically equivalent performance decrements on incongruent versus congruent trials on both tasks. However, within the schizophrenia group, the incongruency effect was significantly greater in the emotional versus non‐emotional task. These data suggest that, while patients with schizophrenia were able to employ contextual response cues to override competing emotional responses, they were slower to resolve emotional versus non‐emotional response conflict. When patients were subdivided according to the presence or absence of disorganized symptoms, this effect was confined to patients with disorganized symptoms.  相似文献

We evaluated the dual-pathway model to creativity in a motor context. The model describes separate flexibility and persistence pathways that are affected differently by breadth of attention and working memory. Motor creativity was tested using a divergent doing task. In Experiment 1 participants performed the divergent doing task after attention was broadened, narrowed or not manipulated. In Experiment 2, the divergent doing task was performed with a low or high working memory load. We found that a broad attention increased flexibility but not persistence. Also originality was unaffected. Taxing working memory did not affect persistence, flexibility or originality. The results provide partial support for the dual-pathway model in motor creativity. Discusion focusses on increased demands for the appropriatness of a solution in divergent doing relative to divergent thinking and to degree to which this implies a more general shortcoming of the dual-pathway model.  相似文献

ABSTRACT

Neuroscience has fundamentally changed the understanding of learning and memory within recent years. Here, the authors discuss a number of specific areas where they believe new understanding of the CNS from basic science is having a fundamental impact on neurorehabilitation and is leading to new therapeutic approaches. These areas have constituted a basis for development of some basic principles for neurorehabilitation: Optimal rehabilitation should involve (a) active (patient) participation in the training, (b) training that does not only involve many repetitions, but also continues to challenge the skill of the training person, (c) motivation and reward, (d) intensive training and practice over a long time, (e) careful organization of the training in relation to other activities, and (f) incorporation of other potentially beneficial parameters such as sleep and diet. It should in this relation also be pointed out that albeit neurorehabilitation may be predicted to have the most optimal effect early in life and as soon after injury as possible, there is no reason to believe that beneficial effects of training may not be obtained late in life or several years after injury.  相似文献

This study examined the peri‐trauma coping responses of 325 survivors, mostly youth, after the July 22, 2011 terror attack on Utøya Island in Norway. The aim was to understand peri‐trauma coping responses and their relation to subsequent post‐traumatic stress (PTS) reactions. Respondents were interviewed face‐to‐face 4–5 months after the shooting, and most were interviewed at their homes. Peri‐trauma coping was assessed using ten selected items from the “How I Cope Under Pressure Scale” (HICUPS), covering the dimensions of problem solving, positive cognitive restructuring, avoidance, support seeking, seeking understanding, and religious coping. PTS reactions were assessed with the UCLA PTSD Reaction Index. The participants reported using a wide variety of coping strategies. Problem solving, positive cognitive restructuring, and seeking understanding strategies were reported most often. Men reported using more problem‐solving strategies, whereas women reported more emotion‐focused strategies. There were no significant associations between age and the use of coping strategies. Problem solving and positive cognitive restructuring were significantly associated with fewer PTS reactions. The results are discussed in light of previous research and may help to inform early intervention efforts for survivors of traumatic events.  相似文献

This study examined the self-control behaviors of participants learning a 3-ball cascade juggle. Participants chose when they would receive one of four types of instructional assistance: (a) instructions; (b) video demonstration; (c) knowledge of performance (KP); and (d) knowledge of results (KR). Juggling proficiency was divided into three categories based on catches per attempt during retention and transfer testing. In general, participants decreased their requests for instructions and video demonstration throughout acquisition. For the most proficient performers, requests for KR increased over practice. Post-experimental interviews revealed that participants requested KR after primarily good attempts and KP after both good and bad attempts. Participant-reported reasons for requesting feedback included the confirmation of success (KR) and identification of technique flaws (KP). Overall, the findings suggest that self-control behaviors are more complex than previously demonstrated and that participants use self-control differently depending upon the type of assistance available, individual preferences, and learning needs.  相似文献

Interpersonal motor coordination is influenced not only by biomechanical factors such as coordination pattern, oscillating frequency, and individual differences, but also by psychosocial factor such as likability and social competences. Based on the social stereotype of “what is beautiful is good”, the present study aimed at investigating whether people coordinate differently with physically attractive people compared to less attractive people. 34 participants were engaged in an interpersonal coordination task with different looking (virtual) agents while performing at the same time a reaction time task. Results showed that participants had more stable motor coordination with the moving attractive than with the less attractive agent, and that the difference in motor coordination could not be interpreted by a specific attention allocation strategy. Our findings provide the evidence that physical attractiveness genuinely affects how people interact with another person, and that the temporal-spatial coordinated movement varies with the partner’s psychosocial characteristics. The study broadens the perspective of exploring the effect of additional psychosocial factors on social motor coordination.  相似文献

To examine patterns of strategy choice and discovery during problem‐solving of a novel locomotor task, 13.5‐ and 18‐month‐old infants were placed at the top of a staircase and encouraged to descend. Spontaneous stair descent strategy choices were documented step by step and trial by trial to provide a microgenetic account of problem‐solving in action. Younger infants tended to begin each trial walking, were more likely to choose walking with each successive step, and were more likely to lose their balance and have to be rescued by an experimenter. Conversely, older infants tended to begin each trial scooting, were more likely to choose scooting with each successive step, and were more likely to use a handrail to augment balance on stairs. Documenting problem‐solving microgenetically across age groups revealed striking similarities between younger infants' strategy development and older children's behaviour on more traditionally cognitive tasks, including using alternative strategies, mapping prior experiences with strategies to a novel task, and strengthening new strategies. As cognitive resources are taxed during a challenging task, resources available for weighing alternatives or inhibiting a well‐used strategy are reduced. With increased motor experience, infants can more easily consider alternative strategies and maintain those solutions over the course of the trial.  相似文献

Abstract

Rescue tasks under heavy strain may act as traumatic events creating stress reactions among the rescue workers. After a major rail accident the rescue workers were examined by questionnaire at 3 and 7 months postaccident using the General Health Questionnaire-28 (GHQ), Impact of Event Scale (IES) and a structured questionnaire made for the purpose. Eighteen percent of the 77 rescue workers who participated in the study had GHQ-case-score and 10% had IES-case-score at 7 months using the usual GHQ-cut-off (4/5) and a low IES-cut-off (19/20). For the case-scorers there was a tendency towards increased GHQ- and IES-scores from 3 to 7 months. Five (6%) had post-traumatic stress disorders (PTSD) of low to moderate severity at 7 months.  相似文献

In Experiment 1, 4‐, 5‐, 8‐ and 11‐year‐old Japanese children (n = 69) and adults (n = 21) explained their reasons for bodily induced reactions (e.g. overeating leads to vomiting) and psychogenic bodily reactions (bodily outcomes originating in the mind, e.g. frustration leads to vomiting). Children gave vitalistic explanations, that is, explaining causal connections by referring to a vital force, in responses concerning bodily induced reactions, whereas adults typically gave these explanations in responses concerning psychogenic bodily reactions. In Experiment 2, 5‐, 8‐ and 11‐year‐old children (n = 96) and adults (n = 24) explained bodily induced and psychogenic bodily reactions, and psychological behaviour, for example, that frustration leads to nail biting. As in Experiment 1, vitalistic explanations tended to be found for psychogenic tasks but were seldom found in either children's or adults' explanations of psychological behaviour. The findings suggest that with age vitalistic causality obtains cross mind‐body implications. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

Impaired motor development can deprive a child of constructive engagement in early motor activities and thus diminish opportunities for the acquisition of key cognitive, social and emotional abilities. The aim of the current study was to test a model where social skills mediate the relationship between motor ability and internalizing symptoms in pre‐primary children. A cross‐sectional research design was employed to assess the mediation model using data from 234 boys and 241 girls aged 4 to 6 years. Structural equation modelling provided support for the mediating role of social skills as assessed by the child's teacher. Replication of these findings in longitudinal studies, elucidating how social skills relate to motor impairment, could have implications for the prevention of psychopathology in young children with motor impairment.
