Sensory phenomena in experimental nerve block

In the course of a series of blocks of the ulnar and lateral popliteal nerves of volunteers a study was made of the manner in which the responses of the subject to sensory stimulation become progressively altered and finally obliterated. These changes are described, together with the manner of recovery, and an account is given of various sensations induced by the blocking and the recovery processes. The relevant literature is briefly reviewed and possible factors involved in these phenomena are discussed.     

Integrating emotion and other nonrational factors into ethics education and training in professional psychology

ABSTRACT

Any professional or scientific discipline has a responsibility to do what it can to ensure ethical behavior on the part of its members. In this context, this paper outlines and explores the criticism that to date the emphasis in ethics training in professional psychology, as with other disciplines, has been on the rational elements of ethical decision making, with insufficient attention to the role of emotions and other nonrational elements. After a brief outline of some of the historical background to the development and understanding of ethical decision making, relevant theoretical and empirical literature on the influence of emotional and other nonrational factors on our ethical decisions is reviewed. The implications of this literature for ethics education and training are outlined, particularly with respect to the use of case studies. An integrative approach is proposed, and conclusions and recommendations are offered with respect to such an approach.     

Modeling the Longitudinal Direct and Indirect Effects of Attitudes,Self‐Efficacy,and Behavioral Intentions on Practice Behavior Outcomes of Suicide Intervention Training

The purpose of this study was to use a longitudinal path analysis to test attitudes toward suicide prevention, self‐efficacy, and behavioral intentions as mediators/moderators of clinical skill development over time following suicide intervention training. Results support a direct effect of attitudes on practice behaviors and self‐efficacy, but no moderating effect. Self‐efficacy performed as a mediator of practice behaviors over time. Behavioral intention had a direct effect on practice behaviors and mediated the relationship between attitudes and practice behaviors. Implications for research and practice are discussed.     

Infants' delayed recognition memory for colour and form

Delayed recognition memory was investigated in 5- and 9-week-old infants after extensive familiarization to a visual stimulus. Both age groups were found to demonstrate memory for colour and form information after a 24 hour delay. In addition the location of testing, relative to the location of familiarization, was found to influence the apparent strength of memory, while there was no effect of sex nor evidence of additivity of stimulus dimensions.     

ARE WOMEN EVALUATED MORE FAVORABLY THAN MEN?

In an experiment in which male and female respondents evaluated the social category of women or men on several types of measures, analysis of respondents' attitudes toward the sexes and of the evaluative content of their beliefs established that they evaluated women more favorably than men. In addition, analysis of respondents' emotional reactions toward women and men did not yield evidence of negativity toward women at the emotional level. Nor did it appear that respondents' very positive evaluations of women masked ambivalence toward them. This research, therefore, provides strong evidence that women are evaluated quite favorably—in fact, more favorably than men.     

Opportunities for learning and social interaction in infant sitting: Effects of sitting support,sitting skill,and gross motor delay

The development of independent sitting changes everyday opportunities for learning and has cascading effects on cognitive and language development. Prior to independent sitting, infants experience the sitting position with physical support from caregivers. Why does supported sitting not provide the same input for learning that is experienced in independent sitting? This question is especially relevant for infants with gross motor delay, who require support in sitting for many months after typically developing infants sit independently. We observed infants with typical development (n = 34, ages 4–7 months) and infants with gross motor delay (n = 128, ages 7–16 months) in early stages of sitting development, and their caregivers, in a dyadic play observation. We predicted that infants who required caregiver support for sitting would spend more time facing away from the caregiver and less time contacting objects than infants who could sit independently. We also predicted that caregivers of supported sitters would spend less time contacting objects because their hands would be full supporting their infants. Our first two hypotheses were confirmed; however, caregivers spent surprisingly little time using both hands to provide support, and caregivers of supported sitters spent more time contacting objects than caregivers of independent sitters. Similar patterns were seen in the group of typically developing infants and the infants with motor delay. Our findings suggest that independent sitting and supported sitting provide qualitatively distinct experiences with different implications for social interaction and learning opportunities.

Highlights

• During seated free play, supported sitters spent more time facing away from their caregivers and less time handling objects than independent sitters.
• Caregivers who spent more time supporting infants with both hands spent less time handling objects; however, caregivers mostly supported infants with one or no hands.
• A continuous measure of sitting skill did not uniquely contribute to these behaviors beyond the effect of binary sitting support (supported vs. independent sitter).
• The pattern of results was similar for typically developing infants and infants with gross motor delay, despite differences in age.
