Obstacle perception by congenitally blind children

The ability to perceive objects from a distance and navigate without vision depends principally on auditory information. Two experiments were conducted in order to assess this ability in congenitally blind children aged 4 to 12 years who had negligible amounts of visual experience or formal mobility training. In Experiment 1, children walked along a sidewalk toward a target location to get some candy. A box was placed along the path on some trials, and the children were instructed to avoid the box if it was present. The children spent more time in the region just in front of the box than in the region just behind it, indicating that they perceived the box and acted so as to navigate around it. In Experiment 2, children attempted to discriminate whether a nearby disk was on their left or on their right. The children performed at above-chance levels, again indicating distal perception of objects. The results of both experiments suggest that blind children with little or no visual experience or formal training utilize nonvisual information, presumably auditory, to perceive objects. The specific nature of this auditory information requires further investigation, but these findings imply that the underlying perceptual ability does not require experience in spatial vision or deliberate training and intervention.     

An Unwillingness to Act: Behavioral Appropriateness, Situational Constraint, and Self-Efficacy in Shyness

ABSTRACT Three reasons for the failure to demonstrate social skills were examined in an attempt to integrate social skills deficit and dysfunctional cognition approaches to self-labeled shyness To assess social skills knowledge, the willingness to demonstrate such knowledge, and self-efficacy expectations for enacting social behaviors, 40 shy and 40 nonshy adults were asked to judge the appropriateness of situated behaviors and indicate whether they characteristically enacted and felt capable of producing them Results suggested that shys may be unaware of the appropriateness of some behaviors in some situations, however, shys and nonshys more often agree on behavioral appropriateness standards Compared to nonshys, shys are less likely to enact social behaviors and tend to have low self-efficacy It was suggested that shys' self-awareness of characteristic responses and low self-efficacy expectations may contribute to failures to demonstrate social skills knowledge     

Stability and Change in Type A Components and Cardiovascular Reactivity in Medical Students During Periods of Academic Stress1

This study examined the effects of academic stress upon components of Type A behavior and cardiovascular reactivity. In a longitudinal design, heart rate and blood pressure responses to the Type A Structured Interview (SI) and additional laboratory challenges were measured in medical students at three points during an academic semester. Sessions 1 and 3 were scheduled during vacation periods; Session 2 took place during an intensive examination week. Results indicated that three “stylistic” components of Pattern A derived from the SI—loud and explosive speech, short response latency, and potential for hostility—increased significantly during the exam period. Similar increases achieved marginal significance for another stylistic component, rapid and accelerated speech. By contrast, global Type A assessments did not increase with academic demands. Cardiovascular reactivity was significantly but only moderately stable across the three sessions, showing less consistency than has been reported in previous research. In addition, there was little evidence in this study that cardiovascular reactivity was potentiated by academic stress or by Type A behavior. These results demonstrate the influence of naturalistic environmental factors on overt behavioral components that have recently been suggested as coronary risk factors. Therefore, it is advisable for future experimental and epidemiological research to examine the social and environmental context in which these behaviors occur.     

Pornography and Degradation

I have taken a Kantian approach to the issue of pornography and degradation. My thesis is that by perpetuating derogatory myths about womankind, for the sake of financial gain, the pornography industry treats the class of women as a means only, and not as composed of individuals who are ends in themselves. It thus de-grades all women, as members of this class, imputing to them less than full human status.     

Attributional mediators of social inhibition and avoidance

People differ in the degree to which they become inhibited and avoidant when they feel socially anxious This study explored the hypothesis that characterological attributions for one's feelings of nervousness in social settings are related to social inhibition and avoidance In a preliminary study, the dimensions people use to explain their feelings of nervousness and relaxation were determined One hundred and twenty-five subjects then completed measures of social anxiousness, inhibition, and avoidance, and made attributions for feeling nervous and relaxed in 10 interpersonal scenarios As predicted, attributions of nervousness to characterological factors, such as ability and personality traits, correlated positively with social inhibition and avoidance Unexpectedly, behavioral attributions for nervousness also predicted inhibition and avoidance     

A short version of a spatial activity questionnaire

Newcombe, Bandura, and Taylor developed a questionnaire measuring participation in space-related activities. The activities were classified as masculine, feminine, or neutral in gender stereotyping. A short version of this questionnaire was developed based on an item analysis of the responses by 485 introductory psychology students (236 women and 249 men). The 10 masculine, 10 feminine, and 10 neutral items chosen for the short form were given to 60 subjects (28 women and 32 men), along with a measure of spatial performance (Piaget's water-level task). Reliabilities (by coefficient alpha) were .79, .77, and .75, for the masculine, feminine, and neutral activity subscales, respectively. As with the original scale, women had a greater preference than men for feminine activities, men had a greater preference than women for masculine activities, and women and men had an equal preference for neutral activities. Masculine activity preference was associated with better water-level performance, with the relationship significantly stronger for women (r=.50) than for men (r=.10). Uses for the questionnaire in research on sex-related differences in spatial performance are suggested.     

Sense of purpose and food insecurity during the COVID-19 pandemic

The COVID-19 pandemic brought new attention to the issues of food insecurity faced by individuals throughout the United States, a stressor exacerbated by disruptions to work status and supply chains. The burden of food insecurity likely carries consequences for whether individuals feel capable of pursuing their broad goals and life engagements; put differently, food insecurity may pose a threat to people perceiving a sense of purpose in life. The current study tested this claim across three samples taken during 2020 (n = 2009), 2021 (n = 1666), and 2022 (n = 1975). Participants completed inventories for perceived food insecurity, sense of purpose, depressive symptoms, and anxiety, among other measures. Results found consistent negative associations between food insecurity and sense of purpose across all three samples. In addition, food insecurity moderated associations between sense of purpose and depressive or anxiety symptoms. Sense of purpose was more strongly negatively associated with depressive and anxiety symptoms for those participants who reported no food insecurity. That said, sense of purpose remained negatively associated with psychological distress even among those reporting food insecurity.     

Self-Discovery and the Role of the Counselor

The major thesis of this philosophic treatise is that unless the counselor realizes in his own life the full import of the search for meaning and self-understanding, he will be unable to empathize adequately with the struggles of another human being who likewise seeks to realize his highest potential. Hindering our self-discovery are the problems of meaninglessness, alienation, and the loss of our freedom. The path toward breaking out of our insulated selves is: (a) to accept fully, on a personal level, a sense of responsibility for what we are, and (b) to realize that self-fulfillment occurs within a social context. The former involves a sense of personal integrity and the latter gives a contextual frame of reference to our search for meaning. The path to self-understanding is difficult and threatening, but as the counselee perceives—on both the intuitive and operational levels—the counselor's sincerity in his own quest for fulfillment, the goals we seek to achieve in the counseling relationship will be facilitated.
