Decrements in children's responses to big and tall: A reconsideration of the potential Cognitive and Semantic causes

The potential causes of decrements in children's understanding of big and tall (Maratsos, 1973, Maratsos, 1974, 10, 367–375) are reconsidered. On the basis of data from English-speaking children, two of these hypotheses, the Strong Cognitive Hypothesis and the Strong Semantic Hypothesis, offer equally plausible explanations for those decrements. However, data from Arabic-speaking children between 2;9 and 6;3, who do not show a similar decrement in their understanding of kabiir, support the Strong Semantic Hypothesis that decrements in English-speaking children's understanding of big and tall are due to their positing semantic features such as [+ Vertical] for one word and overgeneralizing them to related words. This, in turn, supports Carey's (M. Halle, J. Bresnan, & G. Miller (Eds.), Linguistic theory and psychological reality. Cambridge, Mass.: MIT Press, 1978. Pp. 264–293) theory that features are abstracted out for words after children are able to use those words correctly on the basis of stored haphazard examples. Further, the results support the view that children at least sometimes posit features for a word on the basis of its individual privileges of occurrence, rather than on the basis of what that word contrasts with.     

Differential effectiveness of explicit verbal feedback on children's communication skills

In order to specify by which combination of content and form dimensions the explicit verbal feedback comes to be most effective in enhancing communication skills, a training experiment was designed where both dimensions were factorially manipulated. Forty children (mean age, 5–10) were randomly assigned to one of four treatment conditions: Interrogative Cognitive feedback, Declarative Cognitive feedback, Interrogative Perceptual feedback, and Declarative Perceptual feedback. The Cognitive type of feedback specified the successive cognitive steps underlying the comparison activity whereas the Perceptual type of feedback stressed only the necessity of describing perceptual differences when communicating. These two contents of feedback were either provided by a set of standardized questions or of declarative statements, after each trial of a speaking training task. Subjects were given a pretest, and immediate and delayed posttests comprised of a speaking task and a listening generalization task. A 2 (Contents) × 2 (Forms) × 2 (Tasks) × 2 (Post-tests) analysis of variance showed that all subjects performed significantly better on the speaking task than on the listening generalization task and that subjects in the Interrogative Cognitive condition performed better than subjects in the three other conditions, on both post-test tasks. Results emphasize the mutual facilitating effects of the Interrogative Form and the Cognitive Content of explicit feedback and are discussed in terms of the generalization and stability of the induced learning.     

Causal attributions for behaviors consistent or inconsistent with an actor's personality traits: Differences between those offered by actors and observers

The present research was designed to investigate differences in the attributions offered from the actor's perspective and the observer's perspective. It was predicted that causal attributions for behaviors inconsistent with an actor's personality traits would be more situational when offered from the actor's perspective than when offered from the observer's perspective. In contrast, it was predicted that causal attributions for behaviors consistent with an actor's personality traits would be more dispositional when offered from the actor's perspective than when offered from the observer's perspective. Consistent with these hypotheses, extraverts explained introverted behaviors and introverts explained extraverted behaviors more situationally from the actor's perspective than from the observer's perspective. Furthermore, extraverts explained extraverted behaviors and introverts explained introverted behaviors more dispositionally from the actor's perspective than from the observer's perspective. These differences in the attributions offered by actors and observers were attenuated but not eliminated when attributors had access to useful situational information with which to apply the discounting principle.     

Existential measurement: A factor analytic study of some current psychometric instruments

The foray of quantification research into the arena of existentialism and ontology has given rise to several psychometric instruments pertinent to the area. Both exploratory and Confirmatory principal-factor analyses were used to study the relationships among 16 existential scales currently in use in the research literature. Participants were 133 individuals comprised of 74 females and 59 males with a median age of approximately 30.5 years. Approximately one half of the sample was in attendance at the University of Regina and Saskatchewan during the 1976–1977 fall term, while the remainder was drawn from the respective communities. Confirmatory factor analysis supported both the prediction of substantial condensation of existential scales and the presence of an avoidance of ontological confrontation factor. Exploratory factor analysis provided some support of the theory that the avoidance of existential confrontation is a central function of neurosis. Extracted factors were interpreted and examined with respect to implications for existential-ontological theory and research.     

Visual-field differences in picture-word interference

Picture-word interference refers to the fact that if a picture (i.e., line drawing) is presented centrally with a word superimposed, picture-naming latency is longer than if that same picture is presented alone. This phenomenon, like the Stroop phenomenon, seems to be strongly influenced by the nature of the to-be-ignored word. That is, if the word names a member of the picture's semantic category additional interference is observed; however, if the word is replaced by a phonetically unviable consonant string interference is reduced. In the present experiments these effects were examined in the situation where the picture-word stimuli were presented unilaterally in either the left or right visual field. For right-visual-field presentations, phonetic and semantic factors both influenced performance just as in central presentations. As such, these results can be satisfactorily explained in terms of response competition processes. However, the results for the left-visual-field presentations were quite different. Although substantial interference was observed for all types of stimuli, the amount of interference was essentially independent of the linguistic nature of the superimposed letter string. These results do not appear to be explainable in terms of response competition processes. Instead, it is suggested that the best way to explain these results is in terms of the perceptual capabilities of the right hemisphere.     

Perceptions of labor market variables by college students in business,education, and psychology

The perceptions of psychic and economic rewards available in different occupations, the perceptions of psychic and economic costs of preparing for these occupations, and the perceived availability of jobs for college majors in business, education, and psychology is examined. The findings indicate that these different majors have quite similar perceptions of these variables despite major differences in occupational choices. Further analysis examines the relationships of these variables to occupational choice for these three groups of college majors. Although the perceptions of rewards and costs have limited independent relations to measures of occupational choice, benefits-to-costs comparisons are highly related to occupational choice for all three groups of college majors.     

Conflict and integration in career decision schemes

This study investigates three aspects of the way high school seniors (166 males, 187 females) construe occupational alternatives: intensity (how strongly are career considerations related), conflict (how much conflict is involved in these relations), and evaluative accord (to what extent are one's stated preferences in agreement with the positivity with which occupations are rated on considerations). Using a variant of G. Kelly's (New York: Norton, 1955) grid methodology, students rated 10 career alternatives on 10 career considerations. The results indicate that the three variables are significantly interrelated.     

Spatial memory in rats under restricted viewing conditions

In a procedure devised by J. A. Walker and D. S. Olton (Learning and Motivation, 1979, 10, 73–84), rats were placed on two arms of a four-arm radial maze and then were placed in the center of the maze to test how accurately they could choose the alleys on which they had not been placed. In three experiments, the conditions under which animals viewed the environment from the arms were varied. In Experiment 1, both the extent of spatial view and the exposure time were varied factorially in a within-subjects design; animals viewed the environment down a tunnel or had a 180° or 360° view, and subjects were allowed to view the environment for either 2 or 20 sec. In Experiment 2, a between-subjects design was used, in which different groups of subjects were tested repeatedly under either the tunnel, 180°, or 360° conditions. Both experiments showed that animals could avoid the arms previously visited at no better than a chance level of accuracy in the tunnel viewing condition but could perform with progressively better accuracy at the 180 and 360° viewing conditions. Animals also were more accurate in Experiment 1 after viewing for 20 sec than after viewing for 2 sec. Experiment 3 involved a procedure in which restricted viewing conditions were used both during arm placements and testing. Animals tested under tunnel viewing eventually achieved above-chance performance with this procedure, but did not exceed chance as rapidly as groups tested with 45 and 90° views of the environment. These results suggest that animals can learn about their position in a spatial environment through observation and that an animal's ability to locate its position is directly related to the extent of the surrounding environment it can see and the length of time it is allowed to look. The implications of these findings for list and map hypotheses of spatial memory representation are discussed.
