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.  相似文献

Childhood obesity is a serious health concern that is not yet fully understood. Previous research has linked obesity with neurobehavioral factors such as behavior, cognition, and brain morphology. The causal directions of these relationships remain mostly untested. We filled this gap by using the Adolescent Brain Cognitive Development study cohort comprising 11,875 children aged 9–10. First, correlations between the age- and sex-specific 95th BMI percentile (%BMIp95) and neurobehavioral measures were cross-sectionally analyzed. Effects were then aggregated by neurobehavioral domain for causal analyses. Behavioral genetic Direction of Causation modeling was used to test the direction of each relationship. Findings were validated by longitudinal cross-lagged panel modeling. %BMIp95 correlated with impulsivity, motivation, psychopathology, eating behavior, and cognitive tests (executive functioning, language, memory, perception, working memory). Greater %BMIp95 was also associated with reduced cortical thickness in frontal and temporal brain areas but with increased thickness in parietal and occipital areas. Similar although weaker patterns emerged for cortical surface area and volume. Behavioral genetic modeling suggested causal effects of %BMIp95 on eating behavior (β = 0.26), cognition (β = 0.05), cortical thickness (β = 0.15), and cortical surface area (β = 0.07). Personality/psychopathology (β = 0.09) and eating behavior (β = 0.16) appeared to influence %BMIp95. Longitudinal evidence broadly supported these findings. Results regarding cortical volume were inconsistent. Results supported causal effects of obesity on brain functioning and morphology. The present study highlights the importance of physical health for brain development and may inform interventions aimed at preventing or reducing pediatric obesity.

Research Highlights

  • A continuous measure related to obesity, %BMIp95, has correlations with various measures of brain functioning and structure
  • Behavioral genetic and longitudinal modeling suggest causal links from personality, psychopathology, and eating behavior to %BMIp95
  • Results also indicate directional links from %BMIp95 to eating behavior, cognition, cortical thickness, and cortical surface area
  • Obesity may play a role for healthy brain development during childhood

Nonmainstream body modifications appear as a social and psychological phenomenon that has been explored from many angles: as identity construction, self-ownership vindication or masking of mental distress. The purpose of this research is to approach this issue, implicating psychic reality constitution and the peculiar way a subject performing these modifications links the three registers of reality according to Lacan: the Real, the Symbolic and the Imaginary. A qualitative research on a single case was carried out, based on in-depth interviews. The participant has performed multiple extreme body modifications within a transformation project he calls: “alien cyborg”. They include, tattoos, mutilations, and suspensions, among others. The interviews delivered several themes related to the three main categories corresponding to the Lacanian registers. The themes reveal the way the subject lives the body's jouissances and how he deals with them standing on each register. The body project as nomination of an unrepresentable inconsistency of the body and pain control, “normalcy” and “perfectionism” as main signifiers sustaining the whole chain, and a reshaping of the body image that can be sustained by the Other's gaze. The project raises as a means of building a specific connection with reality and projecting his body in a space where there seems to be no limitations.  相似文献

Disturbing emotions that act as bodily cryptograms waiting to be deciphered are currently understood as intra-psychic trauma. The author briefly discusses Fordham's concepts of deintegration and primitive identity, as well as early patterns of mother-infant attunement to describe how the empathic capacity of the analyst is dramatically challenged in helping patients to give birth to unbearable emotions that remain an undifferentiated entity. Referring to Ogden's understanding of the mechanism of projective identification, the author will explore how unconscious mental processes in the analyst and the patient can work at re-activating failures in the deintegrative process. Clinical material is presented to show how unconscious psychic events that affect the patient but cannot be known consciously can be born into mind by the analytic couple.  相似文献

Successful health assessments are ongoing and rely on a clinician/client interaction, which is influenced by both the client’s and the clinician’s beliefs about their bodies. These beliefs about the human body arise out of religious and cultural contexts. Theories often explain cultural context by comparison of differences and similarities between the client and the clinician and/or between the client and the dominant culture. This approach can carry a bias inherent in the comparison to dominant beliefs held by those with the most power and economic advantage. The author suggests an existential approach in which client and clinician bodies interact each as adept, autonomous individuals with a conglomerate of beliefs about body and health.The author is an Interdisciplinary PhD candidate in Music Therapy and Health Psychology at the University of Missouri-Kansas City Conservatory of Music. Her research goals include the interrelationship of music, spirituality, and cardiovascular health. She is a Board Certified music therapist and has served in that capacity since 1980 in mental health facilities, hospice, and private practice.  相似文献

If the imago Dei is not a taxonomic definition but rather something that is performed in context, what are the implications for questions of human enhancement and the development of artificial intelligence (AI)? The author considers Alistair McFadyen’s performative vision of the imago Dei, one that actively seeks humanity in concrete situations, in the context of human enhancement and AI, asking the questions, ‘Does becoming cyborg through human enhancement make us less bearers of the divine image?’ And, ‘Can AI ever be considered to be in the image of God?’ Briefly tracing the shift in perspectives on the imago Dei, before considering what a performance of the image might look like, the author proposes three performances that have significant implications for questions about what it means to be human. To be an image-bearer is not dependent upon human DNA or species membership, but on an optative performance of the imago Dei.  相似文献

We predicted that an expectancy judgment about acquiring a feared fat self and an expectancy judgment about acquiring a hoped-for thin self would mediate dispositional optimism on positive body image. We also predicted that the mediation pathway through the feared self would be significantly stronger than that through the hoped-for self. Participants were 208 female college students who reported their age, height and weight and completed measures of dispositional optimism, the likelihood of acquiring the feared fat and hoped-for thin selves, and positive body image. Statistical analyses revealed that only the perceived likelihood of acquiring the feared fat self mediated dispositional optimism on positive body image. Implications for future research are discussed.  相似文献

While the biomedical model is still theleading paradigm within modern medicine and healthcare, and people with generalised chronicmusculoskeletal pain are frequent users of health careservices, their diagnoses are rated as having thelowest prestige among health care personnel. Anepistemological framework for understanding relationsbetween body, emotions, mind and meaning is presented.An approach based on a phenomenological epistemologyis discussed as a supplement to actions based on thebiomedical model.Within the phenomenological frame of understanding,the body is viewed as a subject and carrier ofmeaning, and therefore chronic pain can be interpretedas a rational reaction to the totality of a person'slife situation. Search for possible hidden individualmeanings in painful muscles presupposes meeting healthpersonnel who view the person within a holistic frameof reference.  相似文献

In Western democratic society, the specificity of the bioethical debate over the life-sciences involves bringing together many different study factors. The dilemmas raised by the new scientific discoveries highlight how contemporary common sense is plagued by a profound feeling of anguish over possible future anthropological developments. One of the central problems is the social construction of consent as a psychological strategy seeking to orient public opinion toward accepting new applications of science and technology. On the one hand, the general features in the epistemological analysis of the mind-brain identity are called into question; and on the other, together with all those research directions concerned with the “meaning of life,” we enter the dimension of the complex issue inherent in the possibility of establishing if there exists something transcending thought and what it may be. In both cases a problem is raised on which the meaning of human life and the world depend, while between the two universes described by medical science and ethical-philosophical thought a window of opportunity for important psychological research is opened. In order to understand such phenomena the present article defends the theory that social psychology must adopt as its subject matter “thinking society,” that is, society characterized by discussion and reasoning on themes relevant to bioethics.  相似文献
