Ricoeur’s <Emphasis Type="Italic">askēsis</Emphasis>: textual and gymnastic exercises for self-transformation

This essay examines what the philosophy of Paul Ricoeur can contribute to current debates on the role of spiritual exercise, or askēsis, in philosophical life. The influential work of Pierre Hadot and Michel Foucault has sparked a widespread interest in the ancient model of philosophy, variously described as a way of life, art of living, or care of the self. Ricoeur’s potential contribution to this conversation has been overlooked, largely because he does not discuss these themes explicitly or often. However, Ricoeur’s early phenomenology of embodiment in The Voluntary and the Involuntary offers valuable insights regarding the exercises of self-transformation. After a brief survey of Ricoeur’s concept of askēsis, this essay draws on Ricoeur to demonstrate the merits of physical exercise, or gymnastic, in ethical and spiritual formation. Gymnastic, Ricoeur shows, can be a form of spiritual exercise. The final section of the paper then makes a similarly counterintuitive claim: namely, that reading is an embodied practice that can facilitate the ethical formation of the lived body.     

Pigeons play the percentages: computation of probability in a bird

The ability to compute probability, previously shown in nonverbal infants, apes, and monkeys, was examined in three experiments with pigeons. After responding to individually presented keys in an operant chamber that delivered reinforcement with varying probabilities, pigeons chose between these keys on probe trials. Pigeons strongly preferred a 75% reinforced key over a 25% reinforced key, even when the total number of reinforcers obtained on each key was equated. When both keys delivered 50% reinforcement, pigeons showed indifference between them, even though three times more reinforcers were obtained on one key than on the other. It is suggested that computation of probability may be common to many classes of animals and may be driven by the need to forage successfully for nutritional food items, mates, and areas with a low density of predators.     

Does self-compassion covary with minority stress? Examining group differences at the intersection of marginalized identities

ABSTRACT

Informed by the minority-stress hypothesis and intersectionality theory, this study examines differences in dispositional self-compassion across diverse youth subject to varying levels of structural and interpersonal discrimination. A secondary analysis of survey data from two suburban high schools in a Midwestern state (n = 1872) found significant differences in rates of exposures to stigma processes in accordance to rates of marginalization as estimated by sexual and/or gender status and racial category (minority vs majority), with a large effect. Sexual and/or gender minority students of color (SGmin) reported the highest rates of stigma experiences including exposure to economic hardship, having an incarcerated parent, not trusting the police, assignment of an IEP and exclusionary discipline. However, white SGmin students reported the highest rates of mental health concerns. Sexual gender majority (SGmaj) students of color reported the highest rates of self-compassion while white SGmin students reported the lowest and the negative relation between bullying and self-compassion was stronger for white SGmin students than for SGmin students of color, suggesting that the latter may have developed ways of coping with multiple stigmatized identities that reflect kindness to the self. As scholars seek to understand the role of self-compassion in resilience processes, we suggest emphasizing the strengths of marginalized youth as well as protecting them from the ill effects of bullying.     

Trajectories of Postpartum Maternal Depressive Symptoms and Children’s Social Skills

The vast majority of new mothers experience at least some depressive symptoms. Postpartum maternal depressive symptoms can greatly influence children’s outcomes (e.g., emotional, cognitive, language, and social development). However, there have been relatively few longitudinal studies of how maternal depressive symptoms may influence children’s social skills. The current study (n = 1363) examined the trajectory of maternal depressive symptoms (from 1 month to 36 months) and whether maternal depressive symptoms at 1 month postpartum and the change in symptoms over time (from 1 month to 3 years) predicted children’s parent- and teacher-rated social skills when they were 4.5 and 6.0 years old. A growth curve model indicated that, on average, maternal depressive symptoms declined over time in a nonlinear fashion. Further analyses indicated that after controlling for five demographic factors (child sex, family income, maternal age, mother’s marital status, and maternal education), initial maternal depressive symptoms significantly predicted children’s social skills as reported by mothers. The results support the notion that maternal depressive symptoms during children’s infancy can have long-term associations with children’s social skills. In addition, the results emphasize the importance of intervention and prevention efforts targeting maternal depressive symptoms during infancy, beginning immediately postpartum.     

Differences Between African American and White Research Volunteers in Their Attitudes,Beliefs and Knowledge Regarding Genetic Testing for Alzheimer’s Disease

Genetic susceptibility testing for common diseases is expanding, but little is known about race group differences in test perceptions. The purpose of this study was to examine differences between African Americans and Whites in knowledge, attitudes, and motivations regarding genetic susceptibility testing for Alzheimer’s disease (AD). Before enrolling in an AD genetic testing research trial, 313 first-degree relatives of AD patients (20% African American; 71% female; mean age = 58 years) were surveyed regarding: (1) knowledge about genetics and AD risk; (2) concerns about developing AD; and (3) reasons for seeking testing. In comparison to Whites, African Americans were less knowledgeable about genetics and AD risk (p < .01) and less concerned about developing AD (p < .05), with lower levels of perceived disease risk (p = .04). The results suggest that African Americans and Whites differ notably in their knowledge, beliefs, and attitudes regarding genetic testing for AD. Additional research with more representative samples is needed to better understand these differences.     

The difficult mountain: enriched composition in adjective–noun phrases

When readers need to go beyond the straightforward compositional meaning of a sentence (i.e., when enriched composition is required), costly additional processing is the norm. However, this conclusion is based entirely on research that has looked at enriched composition between two phrases or within the verb phrase (e.g., the verb and its complement in . . . started the book . . .) where there is a discrepancy between the semantic expectations of the verb and the semantics of the noun. We carried out an eye-tracking experiment investigating enriched composition within a single noun phrase, as in the difficult mountain. As compared with adjective–noun phrases that allow a straightforward compositional interpretation (the difficult exercise), the coerced phrases were more difficult to process. These results indicate that coercion effects can be found in the absence of a typing violation and within a single noun phrase.     

Pigeons' categorization may be exclusively nonanalytic

Recent theoretical and empirical developments in human category learning have differentiated an analytic, rule-based system of category learning from a nonanalytic system that integrates information across stimulus dimensions. In the present study, the researchers applied this theoretical distinction to pigeons' category learning. Pigeons learned to categorize stimuli varying in the tilt and width of their internal striping. The matched category problems had either a unidimensional (rule-based) or multidimensional (information-integration) solution. Whereas humans and nonhuman primates strongly dimensionalize these stimuli and learn rule-based tasks far more quickly than information-integration tasks, pigeons learned the two tasks equally quickly to the same accuracy level. Pigeons may represent a cognitive system in which the commitment to dimensional analysis and category rules was not strongly made. Their performance could suggest the character of the ancestral vertebrate categorization system from which that of primates emerged.     

Cognitive dysfunction in depression: neurocircuitry and new therapeutic strategies

Major depressive disorder (MDD) is a disabling medical condition associated with significant morbidity, mortality and public health costs. However, neurocircuitry abnormalities underlying depression remain incompletely understood and consequently current treatment options are unfortunately limited in efficacy. Recent research has begun to focus specifically on cognitive aspects of depression and potential neurobiological correlates. Two fundamental types of cognitive dysfunction observed in MDD are cognitive biases, which include distorted information processing or attentional allocation toward negative stimuli, and cognitive deficits, which include impairments in attention, short-term memory and executive functioning. In this article, we present a selective review of current research findings in these domains and examine neuroimaging research that is beginning to characterize the neurocircuitry underlying these biases and deficits. We propose that deficient cognitive functioning, attention biases and the sustained negative affect characteristic of MDD can be understood as arising in part from dysfunctional prefrontal-subcortical circuitry and related disturbances in the cognitive control of emotion. Finally, we highlight potential new pharmacological and non-pharmacological therapeutic strategies for MDD based on an evolving mechanistic understanding of the disorder.     

Impartial Reasons,Moral Demands

Consequentialism is often charged with demandingness objections which arise in response to the theory’s commitment to impartiality. It might be thought that the only way that consequentialists can avoid such demandingness objections is by dropping their commitment to impartialism. However, I outline and defend a framework within which all reasons for action are impartially grounded, yet which can avoid demandingness objections. I defend this framework against what might appear to be a strong objection, namely the claim that anyone who accepts the theory will be practically irrational.     

Understanding the real value of fractions and decimals

Understanding fractions and decimals is difficult because whole numbers are the most frequently and earliest experienced type of number, and learners must avoid conceptualizing fractions and decimals in terms of their whole-number components (the "whole-number bias"). We explored the understanding of fractions, decimals, two-digit integers, and money in adults and 10-year-olds using two number line tasks: marking the line to indicate the target number, and estimating the numerical value of a mark on the line. Results were very similar for decimals, integers, and money in both tasks for both groups, demonstrating that the linear representation previously shown for integers is also evident for decimals already by the age of 10. Fractions seem to be "task dependent" so that when asked to place a fractional value on a line, both adults and children displayed a linear representation, while this pattern did not occur in the reverse task.
