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

This research examined children's reasoning about expected (i.e., what a peer would do) and prescribed (i.e., what a peer should do) responses to unprovoked, intentional aggressive actions in two contexts: as a victim of such a transgression and as a witness to the incident. Physical harm and property damage items were used in a structured interview format. There were 90 subjects drawn from three elementary school grades (2nd, 4th, and 6th). Children differentiated between the expected and prescribed responses of peers and significant developmental differences in children's evaluations were found. Although the majority of the subjects in all grades denounced retaliation on the basis of concerns about others' welfare, older children stated that peers were likely to retaliate against the perpetrator nonetheless. Across different contexts, older children's responses appeared to reveal a greater independence from authority in negotiating peer interactions. In evaluating the witness's responses to aggressive acts, younger children's expected and prescribed responses were less disparate than that of the older children. The utility of including different vantage points of the child in examining children's social reasoning about aggression and the application of the present findings to social information-processing models are discussed. © 1996 Wiley-Liss, Inc. 相似文献

Measures of salivary testosterone and the personality dimensions of aggression and pro-social behavior were obtained in 306 (155 male and 151 female) university students. Each participant provided two samples of saliva and completed ten self-report personality scales from multiple inventories. A factor analysis of the personality scales produced two factors, an aggression factor and a pro-social behavior factor. Men averaged five times the amount of salivary testosterone as women (99 pg/ml vs. 18.5 pg/ml) and rated themselves as more aggressive and less nurturant. Within each sex, testosterone was positively correlated with aggression and negatively correlated with pro-social personality. Structural equation modelling analyses suggested that a direct effect model best described the relationship between salivary testosterone and the latent personality dimensions of aggression and pro-social behavior. © 1996 Wiley-Liss, Inc. 相似文献

This study was designed to examine the use of court-appointed experts as an alternative to privately retained experts in Dallas, Texas. Surprisingly, there has been little empirical study of court-appointed experts. Our findings suggest one reason for the lack of research. We found that court-appointed experts are used so infrequently that it makes empirical study difficult to conduct. We discuss the implications on this problem for future research. 相似文献

Legislatures and courts have responded prematurely to the problem of prenatal drug exposure through a variety of criminal and civil legal sanctions to deter drug use and to protect fetal health. A review of the case law demonstrates that significant statutory and constitutional difficulties limit the effectiveness of these sanctions and ultimately inhibit their applicability. These constraints require that any governmental intervention through the courts be based upon individual judicial findings of imminent harm to the child and maternal unfitness in neglect proceedings. 相似文献

Research evidence has shown that in childhood, a secure attachment to a reliable caregiver is important for future mental health and well-being. The theoretical and research basis for attachment theory continues to grow. As attachment theory has become more widely adopted there are challenges and opportunities both theoretically and in terms of its clinical use. Disordered attachment has been linked to psychopathology including internalising and externalising disorders. However, there are ongoing implications for researchers and clinicians as only the most extreme forms of attachment disorders are included in the current diagnostic systems. A wide range of reliable and validated observational assessments to classify attachment are available. Owing to the growing popularity of attachment-based interventions there is a need to develop assessments which are practical for use in clinical settings. The use of attachment-based parenting interventions in clinical settings is increasing as they have been found to be effective and relevant. This growth presents opportunities to further refine these interventions, so they are easy to deliver in clinical practice and tailored to different populations. Attachment-based interventions are being widely used in Australia, and this has led to a need to understand and adapt the theory, assessments, and interventions to this context. Attachment-based interventions demonstrate the importance of relationships and provide an important tool to support children and families. For psychologists here in Australia there are many opportunities to develop measures and interventions based on attachment theory that fit into the Australia context. 相似文献
