Empirical Evidence for Extended Cognitive Systems

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.     

Memory Interventions for Persons with Dementia

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.     

Epistemic injustice in mathematics

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.

Distortions and fluctuations in topographic memory

Two experiments dealing with, the learning of a space by map or by navigation approached the questions of equivalency of the cognitive processes involved in spatial information and of response fluctuation. In the first experiment, 11 subjects were asked to situate, six times, 18 lo-cations on a blank map. In the second experiment, the subjects were first given 3 min to learn a map with 12 locations marked, and then asked to reproduce it. The task was repeated six times, using three different maps. This gave us several trials per subject, so that distortion could be distinguished from response fluctuation. In Experiment 1, the range of values was the same for response inaccuracy and response, fluctuation; in Experiment 2, the range was greater for response inaccuracy than for response fluctuation. The results showed that space learning by navigation and space learning by map involve different cognitive processes.     

Aggressive Children and Effective Communication

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.     

Differences in child rearing attitudes between immigrant Chinese mothers and Anglo-American mothers

In order to explore cultural differences in child rearing attitudes, we studied 30 Anglo-American mothers and 30 immigrant Chinese mothers in the US, together with their preschool children and the children's teachers. Mothers completed a measure of child rearing attitudes, children were assessed for perceived competence, and teachers rated children's competence. Results showed that immigrant Chinese mothers were more authoritarian overall, as expected from previous research, but that they also were more likely to encourage independence and demand maturity from their children. Chinese-American children scored higher than Anglo-American children on cognitive competence, and their cognitive competence was related to authoritarian child rearing. The results are discussed in the context of Confucian and American cultural values. © 1998 John Wiley & Sons, Ltd.     

Psychological Entitlement and Ambivalent Sexism: Understanding the Role of Entitlement in Predicting Two Forms of Sexism

Recent research has shown that narcissistic men in the United States express more ambivalent sexism than their non-narcissistic counterparts. The present study sought to extend these findings by hypothesizing that psychological entitlement would be a predictor of ambivalent sexism but that that this relationship may vary by gender. Given entitlement’s associations with hostility and aggression and the previously established link between narcissism and sexism in men, we hypothesized that entitlement would predict hostile sexism in men. Given that entitlement is characterized by a pervasive sense of deservingness for special treatment and goods, we expected that entitled women would endorse attitudes of benevolent sexism. These hypotheses were tested using two cross-sectional samples in the U.S.—a sample of undergraduates from a private university in the Midwest (N?=?333) and a web-based sample of adults across the U.S. (N?=?437). Results from regression analyses confirmed that psychological entitlement is a robust predictor of ambivalent sexism, above and beyond known predictors of sexism such as low openness and relevant covariates such as impression management. In addition, entitlement was a consistent predictor of benevolent sexism in women, but not in men, and a consistent predictor of hostile sexism in men, but not in women. These relationships were largely robust, persisting even when relevant covariates (e.g., socially desirable responding, trait openness) were controlled statistically, although in one sample the link between entitlement and hostile sexism in men was reduced to non-significance when benevolent sexism was controlled for statistically. Implications of these findings are discussed.     

Capturing the multiple facets of mall experience: Developing and validating a scale

Many constructs have been tied to the customer experience in shopping malls, including hedonic shopping motivations, activities, excitement, and emotional and cognitive reactions. Yet the literature has not addressed the notion of the mall experience as a construct in and of itself. The current research aim is to conceptualize the mall experience through the development and validation of a measurement scale. We present a four‐stage process of scale development and validation, based on three studies with four separate samples of mall shoppers, in which the final stage employs the scale to predict mall equity and loyalty. The suggested scale offers a quantitative measurement of four different mall experiences—seductive, functional, social recreation, and social scene—which differ in their components. This work extends theory in understanding, conceptualizing, and measuring the customer experience in the retail space. On the practical level, the developed scale can serve as a means for planning a mall's marketing mix and launching marketing campaigns in order to attract various groups of customers.

The forest and the trees: Examining the association of self-compassion and its positive and negative components with psychological functioning

ABSTRACT

This paper presents two studies focusing on the link between psychological functioning and self-compassion as measured by the Self-Compassion Scale (SCS), especially in terms of SCS components that represent increased compassionate and reduced uncompassionate behavior. Study One examined this association in seven domains – psychopathology, positive psychological health, emotional intelligence, self-concept, body image, motivation, and interpersonal functioning – and found that while reduced negative self-responding had a stronger link to negative emotionality and self-evaluation than positive self-responding, they were roughly equivalent predictors in other domains. Study Two examined the association of compassionate and reduced uncompassionate behavior with sympathetic nervous system and inflammatory activity after stress, and found they equally predicted salivary alpha amylase and interleukin-6 levels in individuals after a stressful situation. Overall, results suggest that both compassionate and reduced uncompassionate self-responding are central to self-compassion and that both help to explain its link to healthy psychological functioning.
