Antecedents to Fechner's law: the astronomers J. Herschel, W. R. Dawes, and N. R. Pogson

The history of the stellar magnitude scale is briefly traced from the second century b.c. until the middle of the nineteenth century. It becomes clear that astronomers formulated "Fechner's Law" by about 1850. While Fechner is credited with the grander view of things, the contention is made that the astronomers John Herschel, W. R. Dawes, and N. R. Pogson have not been given their due by historians of psychology.     

Young children's use of temporal and spatial order information in short-term memory

Encoding and retrieval of temporal and spatial order information was investigated in the free recall and probed recognition performance of 3-, 4-, 5-, and 6-year-olds. In both tasks, three line drawings of familiar objects were presented successively in different spatial locations, so that temporal order was not confounded with spatial order. Subjects of all ages revealed an organization for the stimulus display based on the temporal sequence of presentation. With increasing age, subjects began recall more often with the first item so as to take advantage of this sequential organization. In the probed recognition task, subjects were asked questions requiring the use of temporal or spatial order information. Performance by the older subjects indicated that information about temporal and spatial order could be simultaneously encoded. The results are discussed in terms of a context theory derived from Estes's hierarchical association model.     

Self-esteem,self-perceived abilities,and vocational choice

This research tested the theory that self-esteem acts as a moderating variable in the occupational choice process. The theory was not supported when the relationships between self-esteem, self-perceived abilities and abilities perceived as required in occupations were examined. Rather, the data were consistent with the self-implementation theory of vocational choice. However, it was found that those with high self-esteem were more likely than those with low self-esteem to see themselves as possessing the abilities they saw as necessary in their chosen occupations.     

Pooling peripheral information: Averages versus extreme values

Suppose, as an idealization, that sensory intensity is coded in peripheral channels as identical Poisson pulse trains with intensity parameter a power function of signal intensity. Discrimination models based on either an average count computed over a fixed time or an average time computed for a fixed count per channel have difficulty in fitting the Weber function ($\text{ΔI}\text{I}$ versus I) if the free parameters are constrained to ranges determined from other experiments (magnitude estimation, reaction time). Here we study a different decision rule, namely, the most extreme observation in either the counting or timing mode. Our extremum-counting model, but not two timing ones, accounts very nicely for the Weber function. However, the ROC curves for these extremum models, which agree in shape with data of Green and Luce, yield estimates for the intensity parameter which are much larger than predicted by the power function growth used to calculate ΔI and about twice as large as those estimated from reaction time data collected in the same experiment.     

Resistance to satiation of consummatory and instrumental performance

In three experiments rats received training in a straight alley under high hunger and then were tested satiated. Both eating and running continued to occur under satiation, but the two responses were not completely correlated, and continued running did not depend upon continued eating. Further, groups differed in their eating behavior, although all experienced the same satiation procedure, suggesting that eating under satiation is not just a reflection of incomplete satiation. Resistance to satiation of the running response was greater following partial reward than following consistant reward and tended to be greater following small reward training than large reward training, regardless of schedule of reward. Eating during satiation was greater following partial than following consistent reward and was greater if the same reward magnitude was given in satiation as in acquisition than if a different reward magnitude was given. It was suggested that resistance to satiation is an associative phenomenon. Eating and running occur during satiation because the stimuli present during satiation continue to elicit them. The differences between results using rewarded satiation and results using high drive extinction as measures of persistence were attributed to satiation being nonfrustrating.     

Language lateralization and handedness: Estimates based on clinical data

The suggestion that the cerebral representation of language is bilateral in at least some left handers relies on using the proportion of aphasics found in available clinical samples of sufferers of unilateral brain damage as a valid estimate of the probability that aphasia will occur following unilateral brain damage. This results in an overestimate of this probability since the clinical sample includes only cases with both unilateral brain damage and clinical symptoms and excludes cases with unilateral brain damage without clinical symptoms. With adjustment for this overestimate the clinical data are consistent with unilateral cerebral representation of language in left handers.     

On aspiring to present a developmental theory of occupational aspirations: A reader's guide to Gottfredson

L. S. Gottfredson's preceding comment (Journal of Vocational Behavior 1983, 23, 203–212)is characterized by undocumented and arbitrary assertions. Moreover, we still maintain and cite further evidence that the features of the stages she describes represent an implausible account of development. We conclude that there is nothing in either L. S. Gottfredson's original (Journal of Counseling Psychology 1981, 28, 545–579) article or her preceding paper that leads us to alter our belief that the views we present in our own article (Journal of Vocational Behavior 1983, 23, 179–212) will be useful for the future development of vocational theory and intervention.     

Categorical and schematic organization and the development of retrieval strategies

This study investigated the effects of schematic and categorical organization on young children's recall. Preschool and kindergarten children recalled either a taxonomic list or a story in one of two presentation conditions: an alternate condition, in which the material was presented, children recalled it and the procedure was repeated, or a successive condition in which the material was presented twice and children recalled it twice. Although preschool children's story recall was well organized, their list recall was poorly organized, and organization did not increase over recall trials in either presentation condition. In contrast, kindergarten children's recall of both the story and the list was well organized, and their recall was better organized on the second recall trial than on the first in both presentation conditions. These results are discussed in terms of the development of retrieval strategies during the preschool years/     

Convergence between attention variables and factors of psychometric intelligence in older adults

The purpose of the present study was to examine the hypothesis that individual differences on measures of attention would converge with select factors of psychometric intelligence, especially fluid intelligence and short-term acquisition and retrieval. A sample of 83 elderly adults $\text{(}\text{X}\text{= 71}\text{years}\text{)}$ was administered a battery of 17 psychometric ability tests. Tests were selected to mark four psychometric ability factors (Cattell and Horn's dimensions of fluid and crystallized intelligence, short-term acquisition and retrieval, and perceptual speed). Also, seven tasks representing four aspects of attention—decoding processes, selective attention, attention switching, and concentration—were administered. A confirmatory factor analysis was conducted to examine the relationships among the four psychometric ability factors and 11 variables obtained from the attention tasks. Results were only partially consistent with the hypothesized pattern of convergence. Two attention measures had significant loadings on a fluid-type intelligence factor, and one had a marginally significant loading on a short-term memory factor. In general, the greatest convergence occured between attention variables and the ability factor of Perceptual Speed. Results were discussed with respect to previous research on psychometric abilities and cognitive processes, the theory of fluid-crystallized intelligence, and their implications for understanding intellectual aging.
