This research was concerned with the way people identify and categorize letters and digits; the author attempted to answer which of these processes occurs first, with the focus on whether there is a logically determined sequence involved. (Author/RK)

Thoughts, biases, and educated guesses that pertain to experimental psychology as it might relate to the psycho-educational needs of Afro-American children. (Author)

This overview of the field of personality theory evaluates the important features of Raymond Cattell's work. While there are many areas of agreement between Cattell and other personality theorists, his rejection of traditional clinical methods for measurement and experimentation has created controversy as well as an extraordinarily rich…

A study is reported in which subjects aged 8 - 18 years made magnitude estimations of height for targets whose height and distance from them varied. For distances up to 15m, and heights from 5 to 50 cm, size constancy prevailed at all ages. (MS)

The experiment tested the hypothesis that the stress experienced by a person who is unable to control aversive stimulation is not a function of lack of control per se, but of the attribution of causality that one makes for failure to exert control. (Editor)

In the present study, acoustic similarity and word frequency were varied and their effects independently assessed on free-recall-learning (FRL) and paired-associate-recognition (PAR) tasks. (Author)

Both fourth-grade children and adult Ss searched faster for target letters through common words than nonwords (scrambled collections of letters), through third-order pseudowords than nonwords. (Editor)

The purpose of the experiments reported in the present paper was to explore further the characteristics and duration of representational persistence, using the word recognition paradigm of Shepard and Teghtsoonian (1961). (Author)

Summarizes and synthesizes several papers on attribution theory by the author: attribution theory, which concerns how people make causal explanations, has developed within social psychology primarily as a means of dealing with questions of social perception. (JM)

Explains how psychology teachers at the University of Georgia designed preliminary examinations in the psychology graduate program to demonstrate research skills. The prelims centered around choosing, analyzing, and elaborating three research problems. (DB)

Reports on three experiments that: (1) extend the findings of Scarborough et al. (1977) that exposure to single words facilitates lexical judgments of single words, and (2) suggest that recency of exposure may contribute to word "frequency" effects in reading and in learning from written material. (Author/AM)

Presents two experiments which demonstrate that language-generalization tests should tend to decrease Type 2 errors. (AM)

Pigeons learned discrimination rapidly and responded differentially to pictures seen for the first time. The essential feature of a natural discrimination--which is the ability to cope with natural ranges of variation--was approached and earlier experimental results were extended using other classes of stimuli. (Author/RK)

Two experiments are presented in which lateralization of monaural, auditory input affected the evaluation of verbal passages. Discusses lateral differences in evaluating auditory stimuli in the framework of the left hemisphere's specialization for the holistic processing of objective information and the right hemisphere's specialization for the…
