Evidence for differentiation of right hemisphere visual-perceptual functions

Performance on tasks sensitive to right hemisphere dysfunction (facial discrimination and perceptual closure) are reported in eight patients with right hemisphere lesions. Patients demonstrated an apparent double dissociation of performance on the two measures. Site-by-task specificity for the closure task was strongly suggested. Implications for right hemisphere organization and underlying psychological processes are considered.     

Moderate Intuitionism and the Epistemology of Moral Judgment

This paper outlines and defends a moderate intuitionism. The point of departure is the intuitionism of W. D. Ross (1930) in The Right and the Good, conceived as ethically pluralist and epistemologically rationalist. The paper articulates a conception of self-evidence – including mediate as well as immediate kinds – appropriate to a moderate intuitionism, explores some of the resources and varieties of that position, and considers some problems and prospects for a rationalist version of intuitionism. The final section addresses the issue of how best to conceive the nature and grounds of prima facie duty, the problem of whether intuitionism can adequately deal with conflicts of prima facie duties, and the question of how satisfactorily a moderate intuitionism can account for the epistemic status of moral judgments of overall duty and their connection with rational action.     

The relationship between expressed social fears and assertiveness and its treatment implications

Behavior therapists have speculated about the relationship between social fears or social anxieties and lack of assertive behavior. Wolpe (1958) perhaps most clearly suggested such a relationship. “If he [the patient] has been ineffectual in such situations—unable, for instance, to return a faulty garment—I explain how unadaptive fears are at the bottom of this ineffectualness. … p. 116.” Wolpe further assumed that engaging in assertive behavior reciprocally inhibited fear in these same social situations and that assertive responses can be programmed for use in overcoming these fears.In later writings (Wolpe. 1969; Wolpe and Lazarus, 1966) Wolpe seems to have broadened his position concerning the cause of non-assertive behavior. Specifically, he now allows that an individual also may be non-assertive, “… not because of anxiety but because they have never had the opportunity of acquiring the necessary habits. p. 40” (Wolpe and Lazarus, 1966). For these individuals direct efforts in assertive training such as behavior rehearsal, operant conditioning or direct instruction are in order. For these individuals whose lack of assertiveness is due to a ‘phobic reaction’ or strong extrinsic fears, systematic desensitization is recommended in addition to assertive training.Despite this apparent change in position, the intuitively appealing notion that the more socially fearful an individual is the more non-assertive he is likely to be has not received the empirical attention it deserves. Rathus (1973) seems to have provided some indirect evidence pertaining to the relationship between social fears and assertiveness. In the context of evaluating the efficacy of an assertive training method he administered both the 100-item Temple Fear Survey Inventory (TFSI) (Braun and Reynolds, 1969) and the Rathus Assertiveness Schedule (RAS) (Rathus, 1973) to groups of female students receiving either assertive training, a placebo treatment or no treatment. He found that at post-test the assertive training group scored significantly higher than either the placebo or no treatment groups on the RAS and that there were no significant differences in post-test Full Scale TSFI Scores. Fear of Social Criticism Factor Scores or Fear of Social Incompetence Factor Scores although in each case the mean changes toward less fear were greater for the group receiving assertive training. This finding gives little support to the reciprocal relationship between social fears and assertiveness. What is needed is a direct determination of the degree to which social fears and assertiveness are related in a sizeable sample of subjects.     

The restoration of extinguished avoidance responses

Following extensive signaled shuttlebox avoidance training, Fischer 344 rats were given extinction trials until they reliably stopped responding and, thereafter, they received occasional classical CS-UCS pairings during the course of restoration test trials in which shock was absent. Experiment I demonstrated that the classical contingency was both necessary and sufficient for the complete recovery of such behavior. Experiment II revealed that the degree of recovery was not differentially affected by the frequency of such CS-UCS pairings. However, in Experiment III recovery in the presence of this contingency was shown to depend on the number of previous extinction trials, although even after a large number of such trials, a considerable degree of recovery occurred. These findings demonstrated the central role of the classical CS-UCS contingency in restoring a previously extinguished avoidance response.     

Individual differences in the game motives of Own,Relative, and Joint gain

Two hundred and eighteen undergraduates (94 males and 124 females) made decisions in same-sex dyads across four types of 3-choice decomposed games. An analysis of each subject's choices was performed to see if he or she consistently pursued one of the three motives of Own (Individualism), Relative (Competition) or Joint (Cooperation) gain across all four decomposed games. Sixty-six percent of the subjects manifested such consistency, and sex of subject was unrelated to which goal was pursued. Of the remaining 32%, a sizable subgroup ($\text{1}\text{3}$) was shown to be making its choices in an Altruistic fashion, attempting to maximize the outcomes of the other subject. An analysis of variance of the F scale scores of subjects in these motivational categories yielded an effect (p < .025), with the Competitive group having the highest, and the Altruistic group having the lowest mean authoritarianism score. Correlational analyses indicated negative r's between degree of Competition and F score, positive r's between degree of Altruism and F, but no apparent relation between F and either Individualistic or Joint gain choice.     

Holland's personality types applied to the SVIB Basic Interest Scales

The possible relationship between Holland types and the Basic Interest Scales of the SVIB was explored. The VPI and the SVIB were administered to 432 male freshmen at the University of North Dakota. Each subject was classified into one of the six types on the basis of his highest VPI T score.Scores on the twenty-two BIS were analyzed for differences among the six personality types by means of a multiple regression equivalence of the one-way analysis of variance. Twenty-one of the 22 F tests and 19 of the Scheffe multiple Comparisons among the means were significant. The results support both Holland's typology and his hexagonal model of relationships among the types and suggest their use in the interpretation of the BIS.     

The child's memory for actional, locational, and serial scenes

Three-, four-, and six-year-old children (N = 180) were tested for recall of a toy missing from a previously seen display of four toys. Toys were displayed initially as a series (StoS), as a unit (UtoU), or moved from a series to a unit as S watched (StoU). There was a significant increase in memory for the missing toy with age. In addition, children viewing StoU displays remembered significantly more toys than did children viewing the other displays, independent of age. Twenty-five percent of the 6-year-olds rehearsed spontaneously while viewing the displays. Results indicated that the nature of a memory unit does not change with age, that memory improves with age, and that separate visual and verbal memories are operative in Ss in this age range.     

The visual cliff: cardiac and behavioral responses on the deep and shallow sides at five and nine months of age

Cardiac and behavioral reactions of 5- and 9-month-old infants placed directly atop the two sides of the visual cliff were studied. Evidence of a developmental shift in infant responses on the deep side of the cliff was obtained in heart rate, which shifted from the deceleration previously obtained with younger subjects, to the acceleration obtained with the 9-month-olds of the present study. Behaviorally, visual attention on the two sides was similar at 5 months, but differed at 9 months, being significantly greater on the deep side. Limb movement showed less of an increase on the deep side than on the shallow at both ages tested. Negative vocalization and positive vocalization recordings failed to show any significant effects. The cardiac data are interpreted as indicating a possible shift from attentiveness to fearfulness on the deep side with age.     

The reduction of attack instigated aggression

Thirty subjects competed with an opponent in a reaction time task to avoid receiving shock. The opponent initially set only the highest possible intensity shock for the subjects. The opponent then adopted one of three strategies to reduce the intensity of shocks set by the subjects. In one condition the opponent set shock intensities which matched those set by the subject. In a second condition the opponent set shocks which were not contingent upon those set by the subject but which were identical to those set by the opponent who matched the subject's settings. The opponent in the third condition suddenly reduced the intensity of his settings and chose only the least intense possible shock for the subject. All three conditions resulted in reduced aggression. This decrement was greatest and most rapid among those subjects who were exposed to a precipitous decrease in the intensity of attack.
