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.     

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.
