Language and the latent structure of cognitive development (1)

A cross-cultural method was used to explore theoretical implications of the reported association between mastery of the comparative forms in language and development of competency in dealing with difference and equality relations (such as those of Piaget's conservation problems). Since Turkish allows comparisons to be made without the use of a morphologically distinct form (equivalent to: John is to Mary tall), it was selected for contrastive study along with English and Greek which share a similar system for comparisons. One hundred and ten English, Turkish-Cypriot and Greek-Cypriot children (age 4–11) attending school in London were tested on a variety of language, conservation, and multiple classification problems. The results of this testing indicated that language competency does play a significant role during the course of cognitive development, and that variations in language structure can engender parallel variations in the structure of development. Statistical analyses suggested the following specific conclusions: (1) the concrete operations stage is not functionally unified; (2) the structure of development during this stage is multidimensional; and (3) constancy across cultures in the ordering of development during this stage arises, in part, from similarities between their languages in the representation of attribute and difference relations.     

PROMPTS TO INCREASE ATTENDANCE IN A COMMUNITY MENTAL-HEALTH CENTER1

The effect of a brief appointment reminder for mental-health center applicants is reported. A standardized phone message was delivered by an administrative staff member one to three days before the appointment and a sequential experimental design alternating baseline and phone message conditions was used to assess the effects of the procedure. The no-show rate averages were 32%, 11%, 25%, and 14% respectively. The cost of the procedure was $162.00, which was totally recovered when only six appointments were kept. Since over 1000 patients were involved in the study, the return on the investment of $162.00 is considerable. Implications for this procedure are discussed for other community mental-health centers and for other community care-giving agencies.     

An evaluation of reality orientation therapy

An evaluation was made of reality orientation therapy utilizing 14 male patients with dementias of various types. The therapy is designed to improve memory and reduce confusion in elderly and demented individuals. Utilizing a group comparison with crossover design, it was found that the patients improved significantly over sessions on orientation items actually taught during those sessions. However, no significant improvement was found on a series of generalization items consisting of orientation-related questions that were not asked during sessions. Furthermore, there was no generalization to ward activities. It was noted that individual responses to the treatment were quite varied, and so three cases reflecting highly different responses are presented.Indebtedness is expressed to the Veterans Administration for support of this research.     

Effects of imaginal exposure to feared disasters in obsessive-compulsive checkers

The combined effects of imaginal exposure to feared catastrophes and in vivo exposure to external stimuli were compared with the effects of in vivo exposure alone in 15 obsessive-compulsives with checking rituals. The first group received 90 min of uninterrupted exposure in imagination, which concentrated mainly on disastrous consequences, followed by 30 min of exposure in vivo to stimuli-situations which triggered rituals. The second group was given 2 hr of exposure in vivo only. Both groups were prevented from performing rituals. Treatment consisted of 10 daily sessions within a 2 week period.Assessments were conducted before and after treatment and at follow-up ranging from 3 months to 2.5 yr with a mean of 11 months. At post-treatment both groups improved considerably and did not differ. But at follow-up those who received imaginal and in vivo exposure maintained their gains, whereas the group who were treated by exposure in vivo alone evidenced partial relapse on four of the six dependent measures. The results tend to indicate that a closer match between a patient's internal fear model and the content of exposure enhances long term treatment efficacy.     

Self-monitoring and humor production1

According to reviews by Goodchilds (1972) and Lieberman (1977) of research on humor, the least studied component of the humorous event is the humorous person. Results of two studies investigating the relation between individual differences in self-monitoring and humor production are reported. In the first study, subjects completed a self-report measure of humorousness, captioned as many cartoons as possible within five minutes, and performed a three-minute monologue. The second study involved a group-discussion task. As predicted, high self-monitors compared to low self-monitors rated themselves as more humorous, generated more humorous cartoon captions, produced more humorous monologues, and were nominated by group participants as having made more witty remarks. The humorousness of the high self-monitors was discussed in terms of control of affective display and mastery of interpersonal skills required to initiate and maintain social interaction.     

Fairness or discrimination in intergroup behaviour? a reply to Branthwaite,Doyle and Lightbown

Branthwaite, Doyle and Lightbown (1979) argue that minimal intergroup behaviour represents a compromise or balance between fairness and discrimination, that fairness and discrimination are opposed, generic norms of intergroup relations and that one factor affecting their relative weight is status position since, apparently, different status groups attempt to equalize their positions by varying the degree to which they are fair or discriminatory. This reply reviews evidence to show that minimal groups are never fair but always discriminatory to varying degrees and that a generic norm of intergroup fairness is unnecessary to explain why that discrimination rarely approaches maximum. It also argues that the concept of opposed, generic norms has neither empirical nor theoretical value. Finally, it cites findings that the basic tendency in intergroup behaviour is not to equalize but to accentuate evaluative differences between groups (whether of similar or different status) in favour of the ingroup.     

Tri-ethnic alcohol use and religion,family, and gender

Nine different behavioral responses to alcohol by over two hundred ninth-graders in Austin, Texas, were examined in a survey designed to identify the relationship between adolescents' alcohol use, religious affiliation, religiosity, and gender. The relationship between alcohol use and family adaptability was also examined. While religious affiliation was found to be mildly predictive of use, religiosity determined only specific behavior. Gender differences in alcohol use appeared to be narrowing. Family adaptability was the most predictive variable, showing a relationship with six of the nine kinds of alcohol behavior. Future studies of family influences on adolescents' alcohol behavior and alcohol use among females are recommended.     

Context-dependent variation in social stereotyping 3: Extremism as a self-categorical basis for polarized judgement

A large body of research suggests that extremists make more accentuated (‘black and white’) judgements than moderates. This phenomenon has been explained in terms of individual differences associated with extremism or as the product of general processes of social judgement. Self-categorization theory suggests that extremists represent the world in relatively polarized terms only because, and to the extent that, similar others are more similar to them and different others are more different from them than is the case for moderates. This analysis is tested and supported in three experiments (Ns = 61, 101, 69) which (a) manipulate subjects' extremity and reproduce standard accentuation effects, and (b) change the configuration of the comparative features comprising the judgmental context and reverse these effects. These findings are inconsistent with individual difference explanations of accentuation and extend previous social judgemental theorizing. Implications for the conceptualization of extremism are also discussed.     

Discriminating constant from variable angular velocities in structure from motion

We investigated accuracy in discriminating between constant and variable angular velocities for orthographic projections of three-dimensional rotating objects. The reported judgments of “constant” or “variable” angular velocity were only slightly influenced by the projected angular velocities, but they were greatly affected by the variations of the deformation, a first-order component of the optic flow. When viewing either a rotating ellipsoidal volume or a planar surface that accelerated and decelerated over the course of rotation, observers’ tendencies to report a variable angular velocity were increased when the temporal phase of the acceleration pattern increased the range of variation of the median deformation; the tendencies were decreased when the same acceleration pattern was used to decrease the range of variation of the median deformation. These results provide evidence contrary to the hypothesis that the visual system performs a mathematically correct analysis of the optic flow.
