Theories of self-regulation emphasize the special role that the symbolic self may play in approach and avoidance movements, but experimental evidence is lacking. In two experiments (total N = 157), participants moved either a self-relevant (e.g., “me”) or non-self (e.g., “not me”) agent to one of two locations, one occupied by a positive word and the other occupied by a negative word. In both experiments, the movement agent interacted with the destination valence such that it was only the symbolic self that moved more quickly to positive rather than negative locations. These results established a role for the symbolic self in approach/avoidance that had been questioned, thereby supporting both classic and contemporary self-related theories of approach and avoidance.  相似文献

The study analyzes the presence of dyskinesias-reduced-self-awareness in forty-eight patients suffering from Parkinson’s disease (PD). As the association with executive dysfunction is a matter of debate and we hypothesize it plays an important role in dyskinesias self-unawareness, we analyzed the role of dopaminergic treatment on the medial-prefrontal-ventral-striatal circuitry using a neurocognitive approach. Special attention was given to metacognitive abilities related to action-monitoring that represent a novel explanation of the phenomenon.PD patients were assessed using different rating scales that we devised to measure movement awareness disorders. In order to ascertain whether each variable measured at a cognitive-clinical level contributes to predicting the scores of the movement-disorder-awareness-scales, we conducted multiple logistic regression models using the latter as binary dependent variables. We used the Wisconsin Card Sorting Test-metacognitive-version to assess the executive functions of the prefrontal-ventral-striatal circuitry.Data showed that a reduction of self-awareness using the Dyskinesia rating scale was associated with global monitoring (p = .04), monitoring resolution (p = .04) and control sensitivity (p = .04). Patients failed to perceive their performance, distinguish between correct and incorrect sorts, be confident in their choice and consequently decide to gamble during the task.We did not find any association with executive functions using the hypo-bradykinesia rating scale.Our findings indicate that when the comparator mechanism for monitoring attentive performance is compromised at a prefrontal striatal level, patients lose the ability to recognize their motor disturbances that do not achieve conscious awareness.  相似文献

In the summer of 2014 the Swedish Church is celebrating the 100th anniversary of the appointment of Nathan Söderblom as archbishop of Uppsala, and thus head of the Swedish church organisation. As a Lutheran with an enormously broad-minded and broad-reaching approach to ecumenical understanding and community-building, Söderblom shot to prominence in the interwar period not only because of his ecumenical engagement, calling for an evangelical catholicity so stand side by side with the Roman catholic and Orthodox catholic traditions, but also because of his comprehensive secular engagement for peace and understanding between peoples. In the latter context he also acquired a solid reputation as a perhaps less prominent but still noteworthy figure in the history of European integration. This article investigates how, why and to what extent Söderblom’s ecumenical and secular engagements were intertwined. The first part discusses how his biographical and academic background led to such staunch ecumenical positions, while the second part focuses on the secular engagement, which was perceived by Söderblom as necessary to make progress on the ecumenical front in the practical political realities of the 1920s. The final part, comparing and contrasting Söderblom’s views with those of Count Richard von Coudenhove-Calergi and the Pan-European Union, demonstrates why Söderblom’s engagement for Europe had to be limited: unity in Christ is by definition global in nature and therefore cannot be continent-specific.  相似文献

During reading, some information about the word to the right of fixation in the parafovea is typically acquired prior to that word being fixated. Although some degree parafoveal processing is uncontroversial, its precise nature and extent are unclear. For example, can it advance up to the level of semantic processing? Additionally, can it extend across more than two spatially adjacent words? Affirmative answers to either of these questions would seemingly be problematic for serial-attention models of eye-movement control in reading, which maintain that attention is allocated to only one word at a time (see Reichle, 2011). However, in this paper we report simulation results using one such model, E-Z Reader (Reichle, Pollatsek, Fisher, & Rayner, 1998), to examine the two preceding questions. These results suggest the existence of both semantic preview and N+2 preview effects, indicating that they are not incompatible with serial-attention models. We discuss the implications of these findings for models of eye-movement control in reading and provide a new theoretical framework for conceptualizing parafoveal processing during reading and its influence on eye movement behaviour.  相似文献

ObjectivesThis systematic review provides an overview of research elucidating the relationship between fundamental movement skills (FMS) and physical activity (PA) in children and adolescents.DesignSystematic review.MethodProspective studies were identified from searches in Cochrane Library, BioMed Central, Education Resources Information Center (ERIC), PubMed, Scirus and SciVerse Science Direct from 2000 through 2013. We screened the titles and abstracts for eligibility, rated the methodological quality of the studies, and extracted data.ResultsWe identified 23 studies meeting our relevancy criteria. The quality score of the studies ranged from 44% to 89%. Overall relationships between FMS and PA or relationships specific for gender and skill were identified in several studies. The variety of methods for assessing PA and FMS make the comparison of study results difficult. We found strong evidence from cross-sectional studies for a positive relationship between FMS and organized physical activities. Motor skill competency was only of low predictive value for the physical activity level in adults.ConclusionsThe results of this review suggest that a cause–effect relationship between FMS and PA is suspected but has not been demonstrated yet. The identification of a causal relationship appears very important to ensure feasibility of practical implementation. This could provide aids for decision making for teachers and coaches, but also for therapists' decision guidance to create training, lessons and therapy adequate to the target group.  相似文献

相对于其它评价中心技术而言,在无领导小组讨论中考官因素对评分结果的影响尤为重要.本研究主要探讨无领导小组讨论中新手考官的工作记忆与人格对其评分有效性的影响.结果发现,首先,新手考官的评分者一致性较低,评分准确度较差.其次,工作记忆和人格的部分因素分别从不同方面影响新手考官的评分有效性,具体表现在:(1)利他性越强,新手考官评分总均值的准确性越高,且评分结果越宽松;(2)新手考官的决断性越强,对所有应聘者做出有效区分的准确性越高;(3)新手考官的沉稳性越高,对各维度的区分越有效;(4)注意转换和抑制能力对新手考官的晕轮效应及其在各个维度上进行区分的准确度有抑制作用.  相似文献

视觉心理表象是一种基于过去经验的自上而下的加工过程,它是信息表征的一种形式.以往的研究主要采用视觉来诱发表象,但是这很难排除视觉后像的干扰,而且与表象“自上而下”的加工过程不一致.听觉诱发表象很好地解决了视觉后像的干扰问题,也更吻合表象“自上而下”的加工过程,因为被试产生的表象是基于自己过去的经验,从自身出发,主动加工的结果.采用实验法,考察通过听觉通道诱发表象眼动的情况,使用眼动仪记录被试的眼动轨迹.结果发现:(1)不管是运动还是静止的物体,都能诱发表象,在表象时存在眼动行为.(2)运动的物体诱发眼动的程度更大.(3)眼动影响表象的建构,在表象建构中起机能性作用.  相似文献

Because individuals' fundamental right to water is often taken for granted, little is known about why individuals participate in water activism. We examine how individuals identify with and intend to participate in the Italian Water Movement to defend the “public management” of water supply. Building on the collective‐action literature, we test an explanatory model in which the perceived violation of the right to water and group and participative‐efficacy beliefs increase movement identification, which predicts subsequent activism. Study 1 (N = 153 activists) largely confirmed our hypotheses: right violation and participative efficacy uniquely influenced movement identification, which in turn predicted activism. Study 2 corroborated these findings by employing a broader sample of 132 Italian citizens, with right violation, participative and group‐efficacy beliefs predicting movement identification, which in turn predicted activism. We discuss the theoretical and practical implications of these findings.  相似文献

The aim of this study was to investigate the patterns of contralateral motor overflow (i.e. mirror movement) between the homologous body parts on the right and left side, in stroke patients during single-finger and multi-finger maximum force production tasks. Forty subjects, including stroke (n = 20) and normal subjects (n = 20), participated in this study. The stroke subjects maximally pressed force sensors with their fingers in a flexed position using a single (index, middle, ring, or little) or all fingers (all 4 fingers) using the impaired (IH) or unimpaired (UIH) hand, while the non-patient subjects used their right hands for the same tasks. The maximal voluntary forces in the ipsilateral and unintended pressing forces of each contralateral finger were recorded during the tasks. The magnitude of motor overflow to the contralateral side was calculated using the index of contralateral independence (CI). During the single finger tasks, the finger CI was significantly decreased in the UIH (91%) compared with that in the IH (99%) or normal hands (99%). Likewise, the multiple finger tasks showed that the CI was significantly lower in the UIH (84%) compared with that in the IH (96%) or normal hands (99%). However, the maximal forces were significantly lower in the IH relative to those in the UIH and normal hands. These data demonstrate that stroke patients have greater motor overflow from the UIH to the IH.  相似文献
