Stress reactivity and exercise training in premenopausal and postmenopausal women.

Examined the influence of ovarian function on psychophysiological stress responses and determined if aerobic exercise reduced stress reactivity. Fifty premenopausal and postmenopausal women initially were subjected to a public speaking task and an ice-on-the-forehead procedure, during which time their blood pressure and heart rate were monitored and continuous blood samples were obtained. Subjects also underwent aerobic fitness evaluations with a maximum-exercise treadmill test. Subjects were then randomly assigned to a 12-week exercise program of either aerobic exercise (e.g., walking and jogging at a prescribed exercise intensity) or non-aerobic strength and flexibility training and were then reevaluated. Results indicated that postmenopausal women exhibited lower resting epinephrine levels but greater epinephrine reactivity to the speaking task compared to the premenopausal women. There were no differences between premenopausal and postmenopausal women with respect to cardiovascular or catecholamine responses during the cold challenge. Premenopausal and postmenopausal women also achieved comparable improvements in aerobic fitness. However, results of the mental stress testing were complex and provided only partial support for the role of aerobic exercise in reducing stress responses.     

Archetypes of the pandemic

This paper attempts to read the psychological and emotional impact of the COVID-19 pandemic through the archetypal images contained in patients’ dreams. In these dreams, symbols related to the power of nature and to extreme danger are paired with feelings of detachment that seem to point to a traumatic dissociation, due to the archetypal experience that erupts in familiar surroundings. Through the humanization of the ineffable experience, dissociation, which in the beginning of the pandemic showed in high levels of anxiety, panic attacks and depersonalization, can be transformed into the overview needed for the search for meaning. The container for this process of transformation is the analyst, the real, virtual or imagined one, and his or her ability to relate and feel.     

Is Socrates free? The Theaetetus as case study

Most scholars agree that Plato’s concept of freedom, to the extent he has one, is ‘intellectualist’: true freedom is submission to the rule of reason through philosophical knowledge of rational order. Surprisingly, though, there are few explicit linkages of philosophy and freedom in Plato. Socrates is called many things in the dialogues, but not ‘free’. I aim to understand why by studying the Theaetetus, heretofore ignored in discussions of Platonic freedom. By examining the Digression (172c-177c) and Socrates’ ‘dream’ about wholes and parts (201c-206c), I show that describing freedom as ‘rule of reason’ simplifies what, for Plato, is a more tangled skein. In the Digression, philosophers are free in occupying a comprehensive standpoint transcending all limited and partial perspectives. Socrates’ dream, however, shows that logos cannot completely account for the knowledge of complex wholes or for itself as such a whole. Philosophical freedom cannot mean comprehensive discursive knowledge, then, since reason lacks a comprehensive grasp of itself. Socrates dreams of the rational whole, but is aware of why it remains only a dream, rather than wakeful knowledge. This awareness constitutes a freedom attained, not in total liberation from the confines of the partial human perspective, but within those confines.     

A developmental dissociation between category and function judgments about novel artifacts

Two studies investigated the relative importance of information about intended design and current use on judgments about the function (Experiment 1) or category (Experiment 2) of novel artifacts in preschool children and adults. Adults assigned function and name on the basis of information about design across all conditions, while children’s decisions about function dissociated from decisions about category. Function judgments (in both 4 and 6-year-olds) were neutral between design and current use, both when the current use was idiosyncratic (e.g. performed by just one agent) and conventional (performed by many people; Experiment 1). By contrast, where category judgments were required for the very same objects (Experiment 2), children named according to design intentions - but only if the alternate function was idiosyncratic. Judging function and assigning category are thus cognitive tasks that draw on different information across development, a fact that should be captured by theories of developing artifact concept structure.     

Developmental changes in information central to artifact representation: evidence from 'functional fluency' tasks

Research suggests that while information about design is a central feature of older children's artifact representations it may be less important in the artifact representations of younger children. Three experiments explore the pattern of responses that 5- and 7-year-old children generate when asked to produce multiple uses for familiar (Experiments 1, 2) and novel (Experiment 3) named objects. Results showed that while older children tended to produce responses based on the known design function of the object, younger children's responses were more flexible, though still constrained by the mechanical structure of the object. Only when ignorant of a novel object's design function did older children produce more varied functions than did younger children. These results suggest that representations supporting object function undergo change across this period of development, with information about design assuming more importance later than it does earlier.     

Life Satisfaction and Symptoms of Mental Disorder Among Older African American Public Housing Residents

This study examines life satisfaction and symptoms of mental disorder in a sample of 831 older African American residents of urban public housing developments. Symptoms of mental disorder included measures of emotional distress, alcohol-related problems, and cognitive impairment. Subjects reporting less life satisfaction had significantly greater emotional distress. Neither lifetime alcohol-related problems nor cognitive impairment were significantly related to life satisfaction. Stepwise multiple regression analyses indicated that emotional distress subscales accounted for most of the explained variance in life satisfaction. Social dysfunction was the strongest predictor of life satisfaction, accounting for 17% of the variance. Having a confidant, instrumental social support, religious support, or being female also contributed to the explained variance in life satisfaction.     

Reputation-like inference in domestic dogs (<Emphasis Type="Italic">Canis familiaris</Emphasis>)

Humans frequently interact with strangers absent prior direct experience with their behavior. Some conjecture that this may have favored evolution of a cognitive system within the hominoid clade or perhaps the primate order to assign reputations based on third-party exchanges. However, non-primate species’ acquisition of skills from experienced individuals, attention to communicative cues, and propensity to infer social rules suggests reputation inference may be more widespread. We utilized dogs’ sensitivity to humans’ social and communicative cues to explore whether dogs evidenced reputation-like inference for strangers through third-party interactions. Results indicated dogs spontaneously show reputation-like inference for strangers from indirect exchanges. Further manipulations revealed that dogs continued to evidence this ability despite reduction of specific components of the observed interactions, including reduction of visual social cues (i.e., face-to-face contact between the participants in the interaction) and the nature of the recipient (i.e., living, animate agent versus living, inanimate self-propelled agent). Dogs also continued to demonstrate reputation-like inference when local enhancement was controlled and in a begging paradigm. However, dogs did not evidence reputation-like inference when the observed interaction was inadvertent.     

The rapid-smoking technique: Therapeutic effectiveness

The study examined the effectiveness of the rapid-smoking technique in terms of two measures of outcome—post-treatment abstinence rate and reduction in smoking achieved by non-abstinent subjects. A total of 75 volunteers (40 men and 35 women) participated in treatment and were randomly allocated to one of four conditions—rapid-smoking alone; rapid-smoking and relaxation training; rapid-smoking, relaxation and contingency contracting; or contingent rapid-smoking. No significant differences between treatment conditions were obtained. For the total sample, abstinence was achieved by 64% of the subjects immediately post-treatment but the probability of remaining abstinent 12 months later was only 0.33. Immediately post-treatment the non-abstinent subjects reduced their rate of cigarette consumption to 34.2% (SD = 29.3) of baseline smoking but by 12 months average consumption had increased to 82.4% (SD = 28.3) of baseline. It is concluded that rapid-smoking gives rise to substantial short-term changes in smoking behaviour but these effects are not sustained.     

Religiosity and Sexual Activity Among Older Adolescents

This study investigates religiosity, sexual activity, and sexual permissiveness among older adolescents. Eighty-two college students completed a survey that measured religiosity, sexual permissiveness, self-esteem, frequency of recent sexual encounters, and motivators for sexual activity or abstinence. Guilt, prayer, organized religious activity, and religious well-being predicted fewer sexual encounters. Orthodox beliefs, participation in organized religious activities, and highly-rated importance of faith predicted less permissive sexual attitudes. We conclude that guilt and religious activity can be good motivators for decreasing sexual encounters. We recommend that health practitioners encourage participation in religious activity among adolescents.     

Belief-desire reasoning in the explanation of behavior: do actions speak louder than words?

The mechanisms underwriting our commonsense psychology, or 'theory of mind', have been extensively investigated via reasoning tasks that require participants to predict the action of agents based on information about beliefs and desires. However, relatively few studies have investigated the processes contributing to a central component of 'theory of mind' - our ability to explain the action of agents in terms of underlying beliefs and desires. In two studies, we demonstrate a novel phenomenon in adult belief-desire reasoning, capturing the folk notion that 'actions speak louder than words'. When story characters were described as searching in the wrong place for a target object, adult subjects often endorsed mental state explanations referencing a distracter object, but only when that object was approached. We discuss how this phenomenon, alongside other reasoning "errors" (e.g., hindsight bias; the curse of knowledge) can be used to illuminate the architecture of domain specific belief-desire reasoning processes.
