The relativity of ‘absolute’ judgements

Suppose that, with rather few exceptions, the assignment of a number to a stimulus on one trial of a magnitude estimation or category judgement experiment serves as the point of reference for choosing an appropriate assignment on the next trial. This principle of relative judgement—relative to the immediate context—is developed to generate models for both magnitude estimation and category judgement experiments. It is applied, in particular, to the explanation of three, hitherto unrelated, phenomena: these are (a) the limited transmission of information in category judgements; (b) sequential constraints on the resolving power of category judgements; and (c) the autocorrelation of successive numerical magnitude estimates. Finally, some comparison is made between the principle of relative judgement introduced here and other contemporary ideas which have been addressed to one or more of these three critical phenomena.     

A comparison of three methods for scoring figure drawings

Figure drawings obtained from 758 white male medical students were scored using three different methods. Method I involved 16 different physical size measurements; Method II involved six separate sophistication of body concept ratings; and Method III involved 42 separate aspects of the drawings weighted in direct proportion to their relative frequency of occurrence in the sample studied (conventionality scoring). Separate factor analyses of the scores derived from each method revealed that Methods I and II each reflect only a single underlying factor, and that these factors are uncorrelated in the population studied. Method III yielded eight meaningful factors, each of which may be construed as an independent area of conventionality/deviancy. An overall conventionality/deviancy score was also derived. It is believed that these three methods of scoring capture most of the variance inherent in existing figure drawing scoring systems, but that use of all three is necessary for a comprehensive analysis.     

Sex stereotype impacts on competence ratings by children

Female and male children, 67 and 114 months of age, provided ratings of perceived relative competence of male and female stimulus persons who were depicted as engaging in sex-stereotyped professions. Ratings for each of eight occupations were made by allocating 10 plastic chips between the two stimulus persons. After the last trial, children also were asked to recall the occupation last paired with a particular stimulus person. Children at each of three age levels rated as more competent the individual whose sex was consistent with the stereotype for the occupational group presented; the degree of differentiation increased with age. Recall was influenced by the consistency of the stimulus person/occupation pairing with the sex stereotype, but was not related to ratings of competence.A research grant from the University of North Carolina at Charlotte Foundation provided partial support for this research. The authors would like to thank Dr. R. Bruce Irons, principal, and the many teachers at Irwin Open Elementary School who cooperated on this project; William G. Graziano for bringing the chip allocation task to our attention; and Helene A. Hilger for helpful comments.     

Smoking and academic performance

Smokers and nonsmokers were compared on three aspects of academic achievement. Although exactly the same percentage of smokers and nonsmokers passed the first-year university examination, smokers obtained significantly higher marks. Similarly, smokers achieved significantly higher marks in their final year examinations in comparison with nonsmokers. Finally, a comparison of the tutorial essay marks of the smokers and nonsmokers again showed that smokers obtained significantly higher marks than nonsmokers. These data are consistent with the idea that ambitious students adopt smoking in the belief that it will help them study and sustain concentration.     

Word age-of-acquisition and residence time in lexical memory as factors in word naming

Previous reports of age-of-acquisition effects have been theoretically ambiguous since, in any particular individual, word age-of-acquisition is perfectly correlated with the length of time that a word has been known. The study reported in this article attempted to disentangle effects of word age-of-acquisition and length of word residence time in lexical memory. To this end, words varying in recency-of-introduction to British English were presented in a word-naming task to 46 native speakers whose ages ranged from 20 to 58 years. Using subjects’ ratings of the words on age-of-acquisition, it was possible to assess word residence times and to compare the effects on naming speeds of age-of-acquisition and residence times. Regression analyses indicated that age-of-acquisition was a more important factor than residence time in the word-naming task.     

Suicide and rurality in urban society

Recent findings suggest that suicide increases with rurality, but research on rural suicide leaves many questions unanswered. This study specifies problems of community organization as a reason for expecting a positive effect of rurality on the suicide rate. A multiple regression analysis of county data shows that rurality has a substantial positive effect and is, in fact, the best predictor of the suicide rate among several variables selected from the previous literature. Additional research is needed to test the interpretation that rurality contributes to an incomplete, fragmented form of community organization which influences the suicide rate by disrupting primary relationships.
