The measurement of imagery ability

When variations in imagery ability are used to predict task performance, distinct and consistent relationships do not tend to emerge. A selective review of studies is undertaken to outline some basic reasons why individual difference measures of imagery are often so unsuccessful. Relevant studies concerning the learning and performance of motor skills are examined in some detail. It is concluded that the major problem in these studies is the types of imagery tests that have been employed; these tests have not adequately measured imagery ability. A recently developed instrument, the Movement Imagery Questionnaire, which has been designed to assess individual differences in visual and kinesthetic imagery of movement is discussed.     

The role of personality in crowding research

An analysis of variance was carried out on Ss who were tested with a letter-cancellation task under four experimental conditions, two levels each of crowding and disconfirmation of expectancy. Eight types of Ss were distinguished based on sex and high or low scores on E and N. The crowding situation and disconfirmation of expectancy was found to affect extraverts significantly more than introverts, as predicted by the Brebner-Cooper model. It was confirmed that personality is an important variable in crowding research.     

Antisocial and prosocial behavior among contemporary Robin Hoods

Sensation-seeking and related personality traits have been linked to both dedliquency and helping behavior. This suggests that certain stimulus-need characteristics are capable of producing both antisocial and prosocial behavior in the same individual. Forty-nine eigth-grade students in a midwest parochial school completed the Junior Eysenck Personality Inventory, the Sensation Seeking Scale (SSS) and a Deliquency Self-report Form. They were placed into either a low- or a high-stimulus condition, tested for a anxiety and sensation-seeking states and a given request to volunteer.As predicted, Deliquency scores were significantly related to the incidencee of volunteering. Volunteers and delinquents, especially drug users, had significantly higher SSS scores than nonvolunteers and nondelinquents. The high-stimulus condition also had a significantly higher proportion of volunteers. Other relationships were found between N and Anxiety, and E and SSS scores,. Results are discussed in terms of interaction of personality characteristics with stimulus conditions, the ‘Robin Hood Syndrome’ and treatment implications.     

Who we are: The political origins of the medical humanities

The medical humanities were organized, beginning in the late 1960s, by a small group of people who shared a critique of medical education and a commitment to vigorous action to change it. They proposed to create several demonstration programs in humanities education at American schools. Although the group began with a religious orientation, it soon acquired a broader, more secular mission. As a result of shrewd political organizing, the group attracted members from within medicine, and was awarded a grant to promote the medical humanities. This paper describes these events and sets them in the context of the social and medical history of the 1960s and early 1970s.     

Finite-state recall revealed by backward learning curves constructed from confidence ratings

Two experiments were carried out to show that the constancy of Type II d’ in recall is not an artifact, but is due to finite-state processes as suggested by Bernbach (1967). The following conclusions were reached: (1) The constancy of Type II d’ is not an artifact due to the inclusion of intralist intrusions in the class of incorrect responses; (2) backward learning curves constructed from confidence ratings gave clear evidence of all-or-none recall; (3) recall appeared to be all or none whether the subjects learned by rote or with a mnemonic; (4) the discriminability index derived from Luce’s (1959) choice theory did not exhibit constancy over trials, unlike Type II d’ and despite the fact that backward rating curves indicated all-or-none processes.
