We present an empirically supported theoretical and methodological framework for quantifying the system-level properties of person-plus-tool interactions in order to answer the question: “Are person-plus-tool-systems extended cognitive systems?” Nineteen participants provided perceptual judgments regarding their ability to pass through apertures of various widths while using visual information, blindfolded wielding a rod, or blindfolded wielding an Enactive Torch—a vibrotactile sensory-substitution device for detecting distance. Monofractal, multifractal, and recurrence quantification analyses were conducted to assess features of person-plus-tool movement dynamics. Trials where people utilized the rod or Enactive Torch demonstrated stable “self-similarity,” or indices of healthy and adaptive single systems, regardless of aperture width, trial order, features of the participants’ judgments, and participant characteristics. Enactive Torch trials exhibited a somewhat greater range of dynamic fluctuations than the rod trials, as well as less movement recurrence, suggesting that the Enactive Torch allowed for more exploratory movements. Findings provide support for the notion that person-plus-tool systems can be classified as extended cognitive systems and a framework for quantifying system-level properties of these systems. Implications concerning future research on extended cognition are discussed.  相似文献

A conceptualization of psychosomatic distress during pregnancy is suggested, stemming from a developmental psychopathology framework and based on contributions from the psychosomatic and attachment literature. A link is suggested between psychosomatic distress during pregnancy, patterns of representational activity, and transgenerational risks of relationship disturbances. Developmental transformations during pregnancy are reviewed, with an emphasis on the vicissitudes of integrating internalized relationships with a person's family of origin. Psychosomatic theory is used to generate hypotheses about the representational activity of mothers who experience psychosomatic distress during pregnancy. Attachment theory is used to discuss the link between maternal representational activity and the transgenerational transmission of relationship patterns. As an example of psychosomatic distress during pregnancy, relevant literature on severe nausea and vomiting during pregnancy is reviewed, and clinical vignettes are presented to illustrate how this condition may sometimes be a forerunner of mother-infant difficulties.  相似文献

It is possible to design effective, pragmatically useful memory interventions for persons with Dementia of the Alzheimer's Type (DAT). A review of successful memory interventions for such populations is presented. A particularly effective intervention technique, spaced-retrieval, is described and the theoretical basis for its effectiveness is discussed. A detailed account is presented of a spaced-retrieval intervention in which persons with DAT are trained to learn and utilize a strategy, i.e., remembering to use a calendar listing daily activities. Directions for future research in this area are offered.  相似文献

Testing a component of a theoretical model which postulates that low levels of communication effectiveness accompany the social and affective problems presented by aggressive children, the study compared the communication skills of a group of aggressive (n = 49) and nonaggressive (n = 49) elementary school children (selected on the basis of teacher ratings) in a structured and cooperative communication task. Based on direct observational measures of communication effectiveness and aggression, and on teacher, peer, and self-rating measures of peer rejection and depressive symptoms, results showed that (a) aggressive children exhibited less effective communication skills and more disruptive communication skills than nonaggressive peers; (b) aggressive children experienced higher levels of peer rejection and depressive symptoms than nonaggressive peers; and (c) group differences in communication effectiveness could not be accounted for by differences in observed aggression and remained significant, even after controlling for differences in peer status and affective functioning. These findings highlight the role that ineffective communication may play in the development and maintenance of aggression and have important theoretical and applied implications, which are briefly discussed. © 1994 Wiley-Liss, Inc.  相似文献

We investigate how epistemic injustice can manifest itself in mathematical practices. We do this as both a social epistemological and virtue-theoretic investigation of mathematical practices. We delineate the concept both positively—we show that a certain type of folk theorem can be a source of epistemic injustice in mathematics—and negatively by exploring cases where the obstacles to participation in a mathematical practice do not amount to epistemic injustice. Having explored what epistemic injustice in mathematics can amount to, we use the concept to highlight a potential danger of intellectual enculturation.

This paper examines the effect of parental attachment and supervision on fear of crime among adolescent males. Earlier work has suggested that feelings of powerlessness and association with deviant peers have a significant impact on adolescent fear of crime. As the nature of the parent-adolescent relationship is also a key predictor of adolescent self-concept and quality of peer relationships, we felt that parental attachment and supervision should also impact fear of crime. Using self-report surveys from 318 incarcerated adolescent males, we examine the effect of parental attachment and supervision, along with other demographic and contextual variables, on fear of criminal victimization, perceived safety, and perceptions of risk. The results indicate that those boys who are most attached to their parents are less fearful of criminal victimization and feel safer in their environment than do their counterparts with weaker parental attachments. Additionally, those boys whose parents supervise them closely are more fearful of criminal victimization, but have lower levels of perceived risk of victimization. Implications and ramifications for social policies and future research are also discussed.  相似文献

A within-scale meta-analysis was performed on 310 samples of children (ages 8-16; N = 61,424) responding to the Children's Depression Inventory (CDI). Girls' depression scores stayed steady from ages 8 to 11 and then increased between ages 12 and 16. Boys' CDI scores were stable from ages 8 to 16 except for a high CDI score at age 12. Girls' scores were slightly lower than boys' during childhood, but girls scored higher beginning at age 13. There were no socioeconomic status effects and no differences between White and Black samples. However, Hispanic samples scored significantly higher on the CDI. Analyses for birth cohort showed a slight decrease in boys' CDI scores over time and no change for girls. Longitudinal studies demonstrated a marked testing effect.  相似文献
