Paradoxical decrease of imitation performance with age in children

Imitation development was studied in a cross-sectional design involving 174 primary-school children (aged 6–10), focusing on the effect of actions' complexity and error analysis to infer the underlying cognitive processes. Participants had to imitate the model's actions as if they were in front of a mirror (‘specularly’). Complexity varied across three levels: movements of a single limb; arm and leg of the same body side; or arm and leg of opposite body sides. While the overall error rate decreased with age, this was not true of all error categories. The rate of ‘side’ errors (using a limb of the wrong body side) paradoxically increased with age (from 9 years). However, with increasing age, the error rate also became less sensitive to the complexity of the action. This pattern is consistent with the hypothesis that older children have the working memory (WM) resources and the body knowledge necessary to imitate ‘anatomically’, which leads to additional side errors. Younger children might be paradoxically free from such interference because their WM and/or body knowledge are insufficient for anatomical imitation. Yet, their limited WM resources would prevent them from successfully managing the conflict between spatial codes involved in complex actions (e.g. moving the left arm and the right leg). We also found evidence that action side and content might be stored in separate short-term memory (STM) systems: increasing the number of sides to be encoded only affected side retrieval, but not content retrieval; symmetrically, increasing the content (number of movements) of the action only affected content retrieval, but not side retrieval. In conclusion, results suggest that anatomical imitation might interfere with specular imitation at age 9 and that STM storages for side and content of actions are separate.     

中国人的时间知觉广度

时间知觉是社会结构和文化传统的映射,具有深刻的社会文化意涵。本文聚焦时间知觉广度这一概念,探讨中国人的时间知觉广度及其对自我连续性和社会变化观等心理过程的影响。通过综合讨论诸多实验发现提出,中国人具有较大的时间知觉广度,包括具有显著的过去取向和未来取向。较大的时间知觉广度提升了中国人跨时间的自我连续性,并且影响着中国人看待世事变化的变化观,这些特点又进一步影响到其它心理过程,例如对苦难和幸福的解读,在股票市场中的决策等。在一定程度上,这些特点可能是中国人在应对不确定性和重大危机时表现出更强的心理韧性和复原力的心理基础。本研究还指出中国人时间知觉广度具有独特的文化意义,包括整体性思维、过去现在未来互嵌互动和双向延展、与自我连续性和社会结构相关联以及具有道德属性等。基于此,本研究提出了时间知觉广度的文化心理比较模型,并分析了时间知觉广度对自我同一性和文化同一性的影响结果。希望本文能为进一步研究“中国人应对历史危机的心理特征与行为表现”提供科学依据。     

How regulatory focus–mode fit impacts variety-seeking

Variety-seeking research has examined antecedents in terms of contextual factors and individual differences. However, it does not consider the interaction of individual difference factors such as regulatory focus (promotion vs. prevention) and regulatory mode (locomotion vs. assessment) to predict variety-seeking. Drawing on regulatory fit theory, this study introduces a new kind of regulatory fit based on the interaction between regulatory focus and mode (i.e., regulatory focus–mode fit), thereby extending previous work examining fit based on either regulatory focus or regulatory mode in isolation. Results from five studies, including field data from 10,547 music app consumers (text analysis), two preregistered studies, and two online experiments, show that regulatory focus–mode fit (vs. non-fit) decreases variety-seeking. Engagement and attitude certainty serially mediate regulatory focus–mode fit effects. Findings provide implications for consumer segmentation and message framing.     

The beneficial effect of Tai Chi on self‐concept in adolescents

Previous research has documented the beneficial effect of Tai Chi, but most of the studies focused on elders and patients with specific health conditions. The aim of the study was to test whether Tai Chi can help to improve self‐concept in adolescents with a longitudinal study. The sample comprised 160 students from a Chinese middle school; half of students formed the experimental group and the rest formed the control group. A 1‐year Tai Chi intervention was delivered in 60‐minute sessions, five times a week. Both groups were instructed to complete the measure of self‐concept at the beginning and end of the intervention. Statistical analysis shows the significant reduction of good behaviour, intellectual and school status, popularity and anxiety in the experimental group compared with the control group. The results suggest that the Tai Chi intervention could improve self‐concept in adolescents.     

Study of a cognitive effects model in Dohsa‐hou for the elderly

This study investigates the primary factors responsible for cognitive performance improvements as a result of dohsa‐hou (Japanese body‐oriented psychotherapy) for the elderly. The study divided participants into two homogeneous groups: an experimental group that attempted to improve upright balance by performing dohsa‐hou, and a control group to establish the drop‐off period for the effect of performing the given activities. The task processing time of Stroop Test and body sway and the situational anxiety during task processing of Stroop Tests were measured before and after the dohsa‐hou and drop‐off period. The results confirm that only the experimental group improved in body sway, had a shorter Stroop Color Test processing time and lower situational anxiety. From this study, it has been identified that: (a) information‐processing capacities spared for posture control are affected by distribution of processing resources towards solving other cognitive tasks; and (b) the effect of the release of attention from threat‐related information due to a decrease in attentional bias, which accompanied the decrease in situational anxiety, are primary factors in improving cognitive task performance.     

Influence of practice schedules and attention on skill development and retention

Focus of attention during dual-tasks and practice schedules are important components of motor skill performance and learning; often studied in isolation. The current study required participants to complete a simple key-pressing task under a blocked or random practice schedule. To manipulate attention, participants reported their finger position (i.e., skill-focused attention) or the pitch of an auditory tone (i.e., extraneous attention) while performing two variations of a dual-task key-pressing task. Analyses were conducted at baseline, 10 min and 24 h after acquisition. The results revealed that participants in a blocked schedule, extraneous focus condition had significantly faster movement times during retention compared to a blocked schedule, skill focus condition. Furthermore, greatest improvements from baseline to immediate and delayed retention were evident for an extraneous attention compared to the skill-focused attention, regardless of practice schedule. A discussion of the unique benefits an extraneous focus of attention may have on the learning process during dual-task conditions is presented.     

Ratiovitalistic hermeneutics and sport in the perspective of Ortega y Gasset

This work aims to show, in the first place, that the ratiovitalism of Jose Ortega y Gasset is one of the possible lines of the hermeneutic transformation process of contemporary thinking. Nietzsche’s hermeneutical mark on the development of Ortega’s thinking is clear in some very relevant aspects, such as the importance of the body and the innovative notion of life, both of which are decisive issues to understand sport. Secondly, an attempt is made to tap into the rich reflections of Ortega y Gasset on sport, which have a considerable impact on the entire human life, based on the claim of a notion of living body (Leib) and of a new notion of life. Sport forms part of a vital horizon that is not reduced by the narrow utilitarian perspective, but which announces the superior form of human existence, opening up to a festival and creative meaning of life. This requires a discipline that is not merely satisfied with correctly complying with some standards, but which encourages indefinite improvement. The attribute of sport is creative vitality, a new way of understanding life. Because, based on this new vital perspective, homo oeconomicus can no longer be used as a model, but rather, the vital phenomenon understood in a sporting manner is festival, joyful, creative, agonal and Olympic, freely vigorous, a meaningful source of energy. Life is, in principle, creation, a creative experiment, as in the Nietzschean conception.     

Working with chronic and relentless self‐hatred,self‐harm and existential shame: a clinical study and reflections

This paper is the first of a two‐part series which explores some of the theoretical and experiential reference points that have emerged in my work with people whose relationship to their body and/or sense of self is dominated by self‐hatred and (what Hultberg describes as) existential shame. The first paper focuses on self‐hatred and the second paper focuses on shame. This first paper is structured around vignettes taken from a 14‐year analysis with a woman who was bulimic, self‐harmed and repeatedly described herself as ‘feeling like a piece of shit’. It draws together elements of Jung's concepts of the complex and symbol, and Laplanche's enigmatic signifier to focus on experiences of ‘inner otherness’ around which we are unconsciously organized. It also brings Jung's understanding that emotion is the chief source of consciousness into conversation with Laplanche's approach to the transference which is that by being aware that they do not ‘know’, the analyst provides a ‘hollow’ in which the patient's analytic process can evolve. These combinations of ideas are linked speculatively to emerging understandings of the neuroscience of perception and throughout the paper clinical material is used to illustrate these discussions.
