Further exploration memory bias in compulsive washers

The aim of the present study was to replicate Radomsky and Rachman's findings on memory bias in obsessive-compulsive disorder (OCD), using the same procedure but an increased sample size, more specific control groups, and a full analysis of contamination attribution data. Sixteen OCD-washers, 16 OCD-checkers, 16 social phobic patients and 16 non-anxious controls were presented with 50 'clean' or 'dirty' objects. After this incidental encoding phase, participants were asked to freely recall the objects, to rate their anxiety when almost touching each object, and, finally, to attribute each object to one of the two contamination conditions ('clean' or 'dirty'). Verbal episodic memory was also assessed with the California Verbal Learning Test. The results indicate that, contrary to Radomsky and Rachman's findings, OCD-washers did not differ from the other participants in their memory for 'clean' and 'dirty' objects. However, the OCD-washers recalled more accurately the 'dirty' source of contamination than the 'clean' source. This result was specific to the OCD-washers, and suggests a memory bias for contextually threatening information. The differences between our findings and those published by Radomsky and Rachman's are discussed.     

Personality characteristics of highly generative adults as assessed in Q-sort ratings of life stories

The present study compared the personality characteristics assessed in life stories of 40 highly generative adults to those in the life stories of a contrasting sample of 30 less generative adults. Life-story interviews of all 70 subjects were rated with the California Adult Q-Sort (CAQ; Block, 1961). The results were compared to the “expert” generativity CAQ profile compiled by Peterson and Klohnen (1995). The results indicated that highly generative adults were more likely to construct life stories indicative of such positive generativity characteristics as “behaves in a giving way toward others” and “is turned to for advice and reassurance” compared to adults low in generativity. Furthermore, the highly generative adults related life-story accounts in which negative generativity qualities such as “has hostility toward others” and “is self-indulgent” were more uncharacteristic than those expressed in the low-generativity adults' stories. The study adds to a growing empirical literature on the meaning and manifestations of generativity in adult lives and suggests that the CAQ is a useful tool for uncovering personality characteristics expressed in the life-story accounts generated by adults.     

Teaching autistic children to respond to simultaneous multiple cues

A number of studies have shown that autistic children tend to learn new discriminations by responding to only a restricted number of available cues and that this may be responsible for some of their abnormal behavior. Therefore, this investigation assessed the feasibility of teaching autistic children to respond to multiple cues. The results showed that four autistic children could learn a conditional discrimination requiring them to discriminate a multiple-cue complex from each of its two component cues. However, the autistic children did not learn this discrimination in the same manner as normal children. In the early trials, the autistics responded at a higher level to one of the two component cues. Only after many trials did the autistics respond equally on the basis of both component cues. The results of an initial attempt to teach a general set to respond to multiple cues showed that, when an autistic child was taught a series of successive conditional discriminations, the child eventually learned a set to approach new discriminations by responding equally on the basis of both component cues. The results are discussed in terms of understanding and treating autistic children's abnormal development.     

Androgyny,sex-typing,and the perception of masculinity-femininity in handwritings

Sex-typed and androgynous subjects rated the similarity of handwritings on masculinity-femininity and also rated the writings on an absolute scale of masculinity-femininity. The variances of sex-typed subjects' ratings were significantly higher than those of androgynous subjects, indicating that sex-typed subjects differentiated more along the dimension. Sex-typed subjects also agreed more highly with other raters and among themselves than did androgynous subjects. Multidimensional scaling of similarity ratings—using nonmetric multidimensional scaling (Kruskal, 1964; Shepard, 1962), and INDSCAL (Carroll & Chang, 1970)—showed interpretable dimensions along which subjects perceived masculinity-femininity. Further scaling solutions indicated again that sex-typed subjects differentiated more strongly along the dimension of masculinity-femininity and weighted the dimension more highly in making their similarity ratings. The data supported the hypothesis that subjects who monitor their own behavior on a given dimension are more sensitive to cues in others relating to that dimension.     

Does everybody like a liker?

The primary hypothesis examined was that people giving positive evaluations are themselves regarded as more attractive than when they give negative evaluations. This research tests whether this holds when reciprocity is not at issue. Subjects in six experiments were presented with stimulus persons who varied in the proportion of positive to negative evaluations they gave of various attitude objects (political figures, cafeteria workers, cities, movies, and college courses). Giving predominantly positive evaluations did in fact lead to greater liking of the stimulus person in each experiment. This finding held over (1) audio or written interviews with the stimulus persons, (2) a variety of classes of attitude objects, and (3) both within-subject and between-subject designs. Greater liking for likers occurred even controlling for attitude similarity.     

Motivational determinants of coalition formation

Coalition preferences of 300 male and female subjects were ascertained under varying motivational conditions. Two of the experimental conditions repeated the typical three-person coalition paradigm, with a monetary reward (extrinsic motivation) offered for the winning of a luck-determined game. In a third condition, skill rather than luck influenced the outcome and no monetary reward was given for winning (intrinsic motivation). Two additional conditions examined coalition preferences in a mixed-motive situation, with either a small or a large monetary reward offered for winning a skill-related game. In the extrinsic motivation condition, the low and the medium resource persons typically desired to coalesce, contrary to the wishes of the excluded, high resource player. In contrast, the coalition between the low and the medium resource persons also was preferred by the high resource player in the intrinsic motivation condition. Coalition conflict was intermediate in the mixed-motive conditions. In sum, it was demonstrated that coalition formation and interpersonal conflict are dependent upon the motivational determinants of group activity.     

Dominance as a function of cue similarity: A test of the intrinsic cue dominance model

A nonselective model postulating intrinsic cue dominance was tested in simultaneous discrimination tasks involving reversal on one dimension. In this procedure two dimensions are relevant throughout training; however, following initial discrimination training the reward contingency is reversed for one dimension but maintained for the other. Cue dominance was assessed following acquisition of reversal by the use of opposed-cues test trials, and was defined as a greater number of choices of the test compound containing the positive cue of the reversed dimension than of the test compound containing the positive cue of the maintained dimension. In Experiment I, brightness cues dominated orientation cues. In Experiment II, which employed two different sets of relevant cues, more disparate brightness cues dominated the orientation cues for one set and orientation cues dominated less disparate brightness cues for the other. From this, it was concluded that dominance is a function of relative cue similarity.     

Crossed aphasia in an illiterate dextral

An 83 year old illiterate, right-handed woman developed a persistent nonfluent aphasia following a right cerebral infarction (crossed aphasia). Computerized axial tomography localized the lesion to the right posterior frontal lobe.It is suggested that the neural mechanisms involved in learning to read and write may be critical for the complete establishment and maintenance of language dominance in the left hemisphere, and that, in this case, the patient's failure to acquire reading and writing skills altered the normal evolution of language lateralization and resulted in the right hemisphere assuming the dominant role.     

Relationships between the Vocational Preference Inventory and the Edwards Personal Preference Schedule

The Vocational Preference Inventory and the Edwards Personal Preference Schedule were administered to 372 undergraduates. The two instruments were compared using canonical analysis. The analysis revealed three significant relationships between components of the two instruments. The relationships were viewed as supportive of Holland's theory of personality types.
