COMPARISON OF PROTOTYPE AND ROTE INSTRUCTION OF ENGLISH NAMES FOR CHINESE VISUAL CHARACTERS

This study compared prototype and rote instruction of English names for Chinese visual characters. In the prototype condition, participants were taught the meaning of the prototype that served as the distinctive feature of multicomponent characters. In the rote condition, participants traced the character and wrote its translation. Participants learned more rapidly and maintained more words in the prototype condition.     

Compound word effects differ in reading,on-line naming,and delayed naming tasks

Bimorphemic compound words (e.g.,blueberry), bimorphemic suffixed words (e.g.,ceaseless), and monomorphemic controls (e.g.,arthritis) were read in neutral sentence contexts in Experiment 1. The main result revealed longer first fixation durations on compound words than on control and suffixed words. Different effects emerged when naming tasks were used. An on-line naming task revealed substantially shorter naming latencies for compound words than for control and suffixed words. Naming latencies for compound and control words were equivalent in a delayed naming task. These results indicate that on-line naming latencies and word-viewing durations may yield diverging results. They also suggest that activation of constituent words of compound words occurs independently from the specification of conventional word meanings.     

Parafoveal word perception: A case against semantic preprocessing

The present experiment investigated semantic information extraction in parafoveal word perception. An ambiguous word (bank) was presented in foveal vision, and simultaneously a disambiguating word (water, money) was presented in the parafovea. Subjects were required to make a forced choice between two phrases, and the task was constructed so that a correct choice could be made if semantic information about both the foveal and parafoveal word had been obtained. However, the results indicated that the forced-choice results could be explained by two factors: identification of the parafoveal word and correct guessing. Hence, it was concluded that those models of reading which rely on unconscious semantic preprocessing of parafoveal words were not supported.     

DEC performance in the psychology laboratory

A survey of the On-Line Psychology DEC Users’ Group was taken to evaluate DEC’s performance in the psychology research laboratory. Data were obtained for 20 rating scale items and 7 open-ended items in five categories. On a 10-point scale, DEC averaged about 6 on purchasing procedures and documentation, about 4 on delivery time and maintenance service, and about 7 on product satisfaction. The open-ended items provided users’ explanations for the ratings and new hardware and software that users would like to see from DEC in the near future.

Medication effects in the classroom: Three naturalistic indicators

Hyperactive and comparison boys participated in 5-week summer enrichment programs that included classroom activities and structured assessments of peer interaction patterns. During the 3rd and 4th weeks of these programs, a double-blind, methylphenidate-placebo crossover design was implemented within the hyperactive group. Three heterogeneous indicators of everyday behaviors were obtained: number of negative incidents noted by staff, quality of handwriting, and number of times the teacher called the boys' names aloud in the classroom. Medication effects emerged for each of these indicators. When hyperactive boys were taking placebos, they were involved in more negative incidents, their handwriting was poorer, and their names were called more frequently than when the boys were taking methylphenidate. Interrelationships among the measures suggest moderate cross-situational generality of medication responsiveness. Discussion focused on the bandwidth of medication effects and the need to examine the social ramifications of child treatments.This research was supported in part by NIMH grant 29475 and NIDA grant 01070. We gratefully acknowledge the participation of the data coders and the many summer school staff. Special thanks go to Mike Berlin, Barry E. Collins, and Sharon Dotemoto. Methylphenidate and placebo were supplied by Ciba-Geigy, Summit, New Jersey.     

Alcoholics in inpatient,short-term interactional group psychotherapy: an outcome study

The differential outcome of 100 psychiatric inpatients distinguished by the presence/absence of secondary alcoholism was examined in shortterm closed group psychotherapy. Alcoholics did not differ from the general sample in outcome, but displayed distinct active/aggressive personality features. Group outcome was not affected by the presence/absence of alcoholic members.     

What’s happening in CAI: A survey of ongoing projects

As there are more CAI papers in this year’s “Computers in Psychology” program than in any past year, the membership was surveyed to provide a broad overview of current trends. This is a report of the obtained data (1) on what courses use CAI and the hardware supporting those courses, (2) on the software and “courseware” involved, (3) on CAI record-keeping and evaluation procedures, and (4) on the financial costs and educational benefits of the various projects.     

Early lexical development in children with focal brain injury

Early lexical development in 27 children with focal brain injury was studied cross-sectionally and longitudinally. Data were obtained from children between 12 and 35 months of age who acquired their lesion prenatally or within the first 6 months of life. Results for the group as a whole provide clear evidence for delays in lexical comprehension and production, and for a larger number of comprehension/production dissociations than would be expected by chance. In addition, a significant number of children were observed having unusual difficulty mastering predication and/or using an atypically high proportion of closed class words (suggesting reliance on holistic/formulaic speech). Analyses by lesion type revealed no effect of lesion size. Analyses according to side of lesion revealed that children with right-hemisphere damage produced a higher proportion of closed class words, suggesting heavy reliance on well-practiced but under-analyzed speech formulae. Children with left-hemisphere damage were slightly better in comprehension than children with right-hemisphere damage. In addition, left posterior lesions were associated with greater delays in expressive language, and delays were more protracted in children with left posterior damage. No differential effects of left posterior damage were found for lexical comprehension.     

Joint DEC and microprocessor users’ groups report

The results of a joint meeting of users of Digital Equipment Corporation (DEC) computers and various microprocessors are reported. The meeting included a review and a discussion of Unix and of recent hardware and software products from DEC.
