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.     

A transgenerational conceptualization of psychosomatic distress during pregnancy: Implications for infant mental health

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.     

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.

     

Pairing People with Products: Anthropomorphizing the Object,Dehumanizing the Person

We present the first empirical integration of anthropomorphism and dehumanization, two intrinsically linked processes representing the extent to which the concept of humanness is activated for a given target. Across several experiments, we demonstrate that pairing a person and object in an ad, while focusing respondent attention on the object, leads to its being anthropomorphized and evaluated better compared to presenting it alone. However, compared to presenting a person alone, the same pairing leads to inferior evaluations of the person through a process of dehumanization. We rule out two alternative explanations for these effects, namely the transfer of an object's qualities to the person and consumption associations, and conduct a post‐test that provides additional support for our proposed activation/inhibition of humanness account. Finally, we inspect several moderators, finding that anthropomorphism only occurs with moderately and highly functional objects and dehumanization occurs irrespective of the person's gender or fame. By incorporating the literature on dehumanization, we propose new research questions to motivate future inquiry.

Age,gender, race,socioeconomic status,and birth cohort differences on the children's depression inventory: a meta-analysis

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.
