Response and associative phase components of elaborative prompt effects in children's noun-pair learning

The effects of aural and pictorial elaborative prompts were estimated separately for response and associative phase components of children's nounpair learning. A 20-item list of noun pairs was administered individually to 200 second- and third-grade children by the method of paired-associates. Indices of response learning (free verbal recall and pictorial identification) revealed equivalent effects among prompt conditions whereas measures of associative learning (multiple-choice pictorial-recognition tests) demonstrated substantial performance facilitation as a function of both aural and pictorial elaborative prompts. This outcome was regarded as an unequivocal identification of the locus of elaborative prompt effects in children's nounpair learning.     

An auditory evoked potential study of consonant perception in different vowel environments

Auditory evoked responses (AER) to series of consonant—vowel syllables were recorded from temporal and parietal scalp locations from 20 right-handed female college students. Averaged AERs were submitted to principal components analysis and analysis of variance. Seven components of the group's AERs were found to reflect various aspects of the stimulus parameters. One component reflected changes over only the left hemisphere to different consonants independent of the following vowel sound. A second component changed systematically over both hemispheres in response to only consonant changes. A third component systematically changed for the different consonants depending on the following vowel.     

The early history of behavior modification of stuttering: A view from the trenches

The attitudes of 644 employers toward stuttering were studied through the use of a questionnaire which required the respondents to indicate their strenght-of- agreement to seven attitudinal statements concerning stuttering. While rejecting the suggestion that stuttering interferes with job performance, the employers agreed that stuttering decreases employability and interferes with promotion possibilities. It was concluded that although stuttering may not typically interfere with job performance, it is a significant vocationally handicapping problem.     

Consistency of the labial temperature change measure of human female eroticism

Six adult, human female volunteers participated in a study to determine the consistency of their pattern of sexual arousal to two erotic films over two experimental sessions. Sexual arousal was assessed objectively by means of continuous measurement of temperature changes of the labia minora and subjectively by periodic self-ratings. Each subject developed increases in labial temperature to both film presentations that ranged from about 0.10°C to 1.36°C above basal levels. The amount of temperature change in a subject's labia minora during the first film presentation was significantly correlated with that during the second film, and there was a reasonable degree of consistency across the two sessions with regard to the rate at which the subject's labial temperature subsided towards basal levels after the cessation of erotic stimulation. Labial temperature changes and subjective ratings were also significantly correlated during each of the two film presentations.     

Internal external control of reinforcement as a determinant of study habits and academic attitudes

This study tested Rotter's hypothesis that internals would show more achievement-striving behaviors than externals using a direct measure of such behavior. Rotter's I-E scale and the Survey of Study Habits and Attitudes (SSHA) were administered to 123 male and 130 female undergraduate subjects. Significant sex differences were found on the SSHA scales but not on the I-E scale. Results indicated significant differences between internals and externals within each sex in terms of the average SSHA profiles and the individual SSHA scales. Using H. L. Mirels' (Journal of Consulting and Clinical Psychology, 1970, 34, 226–228) I-E subscales, similar results were obtained with the personal-control scale but not the political-control scale. Results provide additional evidence supporting the multidimensional interpretation of the I-E scale.     

Sex-role self-concept and attitudes related to occupational daydreams and future fantasies of college women

This study explored the relationship of sex-role self-concept and general attitudes toward women's roles to patterns of career preferences and to career salience among 50 undergraduate women. Sex-role self-concept was measured by the Bem Sex-Role Inventory, and attitudes by the Attitudes Toward Women Scale. Patterns in career preferences were determined by studying the degree of gender dominance in past occupational daydreams as well as in present college major and intended future occupation. Career salience was measured using a content analysis of written future fantasies. Sex-role self-concept was related to past occupational preferences, with masculine-typed women showing a pattern of nontraditional daydreams compared to those of feminine-typed women. Attitude variables were related to present career choices, with liberal women in more male-dominant fields than conservative women. Both self-concept and attitude variables were related to career salience, measured by the proportion of fantasies about the future devoted to work themes. Masculine women showed evidence of more career salience than androgynous or undifferentiated women, and liberal women more than conservative women.     

Effect of perceived choice,expected outcome,and observed outcome of an action on the causal attributions of actors

An experiment was conducted to test the hypothesis that actors' causal attributions for success and failure would be affected by the degree of perceived choice they had in taking an action. Actors either were assigned, or selected one of four therapeutic outlines which were expected to have either a positive or a negative effect, and which actually had either a positive or negative outcome on a purportedly phobic person. For negative outcomes, it was predicted that perceived choice would induce a sense of personal responsibility when a positive outcome was expected, and lead actors to attribute more responsibility to themselves as a result. Results supported this prediction. For positive outcomes, however, actors attributed responsibility to themselves regardless of expectancy or choice. Actors were also found to attribute generally more responsibility to themselves for positive than negative outcomes. Results were discussed in terms of self-esteem motivation and the information available to the actor.     

The relationship between men's endogenous levels of testosterone and their penile responses to erotic stimuli.

The endogenous levels of testosterone of six nonclinical, sexually functional men were compared to the magnitude and speed of development of their objectively measured penile erections to repeated presentations of an erotic film und to their self-reported sexual activity. Plasma testosterone concentrations were significantly correlated with two measures of the magnitude of film-elicited sexual arousal (i.e., both peak and mean erection) and with one measure of the speed of development of sexual arousal (i.e., the latency to 90% of full erection) but not with the other (i.e., the latency to 20% of full erection). There was also a significant inverse relationship between testosterone levels and their reported frequency of orgasm by any means. but the reported time from their last orgasm was not related to testosterone levels.     

Processing of identity and position information in normal and disabled readers

Processing of identity and position information was investigated in normal and disabled readers at two grade levels (third/fourth grade and sixth grade). Two partial-report tasks were used. The identity task consisted of visual presentation of a five-letter array, followed by a probe letter. Subjects responded yes for a match and no for a mismatch (identity response). The identity + position task was identical except that an additional response was required on correct yes trials: subjects reported the position of the probe letter in the array (position response). Both grade level and reading ability differences were found on the identity response measure, but not on the position response measure. Results were inconsistent with the hypothesis that disabled readers have difficulties in processing order information. Reader ability differences in identity processing attenuated somewhat with age. Serial position functions for both identity and position responses suggested the presence of a left-to-right scanning operation in both age and ability groups. Reader ability differences in processing letter identities were discussed in the context of current theories of reading acquisition.     

The right hemisphere and temporal processing of consonant transition durations: electrophysiological correlates

Auditory evoked responses (AER) were recorded from frontal, temporal, and parietal scalp regions to a series of consonant-vowel syllables which varied in the duration of the consonant transition. Multivariate analyses of the AER waveforms identified one component of the AERs occurring only over right hemisphere regions which discriminated between differences in transition durations. A second component detected over only left hemisphere areas discriminated differences in place of articulation. These data are consistent with previous behavioral and electrophysiological reports that the right hemisphere is sensitive to temporal discriminations.     

Characteristics of taste-mediated environmental potentiation in rats

When rats drink a novel flavor in a distinctive environment and are injected with lithium, potentiated aversions are established to the environment as evidenced by the animals' unwillingness to consume a familiar, nonaversive flavor in this environment. Experiment 1 demonstrates that this potentiation is due to the presence of both the distinctive taste and the environmental cues on the conditioning trials, not simply aversive conditioning to each element or to generalization between the two elements. This potentiation phenomenon was shown to be sensitive to the novelty of the potentiating flavor in Experiment 2. Experiment 3 demonstrated that second-order conditioning is difficult to establish using these procedures, although Experiment 4 revealed that postconditioning extinction of the aversive flavor interfered substantially with environmental potentiation. These outcomes are discussed in terms of their implications for adaptive adjustments in feeding behavior as well as for more general conceptions of associative learning.     

Predictors of organizational commitment: The study of part-time army reservists

A predictive model built upon a multiple role conflict/felt responsibility conceptual framework and containing six previously untested predictors and nine previously tested organizational-related predictors of organizational commitment was investigated. The sample consisted of two battalions of U.S. Army Reserve members. Stepwise multiple regression analysis utilizing a double cross-validation design on each battalion was the data analytic technique. Increased job satisfaction and stronger intent to stay consistently entered each equation as the first and second predictors, respectively. Group cohesion also appeared in more than one equation. The variance explained across the four cross-validated samples averaged .46 and the results were very stable. The importance of the investigation of commitment for this part-time, voluntary organization was discussed, as were future research directions regarding organizational commitment.     

A multimethod analysis of selected self-esteem measures

This study investigated the convergent and discriminant validity of selected measures of global self-esteem and social self-esteem, using the multitrait-multimethod design. Orderliness was included as the third trait for appraising the discriminant validity of the self-esteem measures. Each trait was measured by three different methods: true-false self-report inventory, multipoint self-report inventory, and simple self-ratings. The Tennessee Self-Concept Scale and the Coopersmith Self-Esteem Inventory (short form) were the selected measures of global self-esteem. The revised Janis-Field Feelings of Inadequacy Scale and the Self-esteem scale of the Jackson Personality Inventory were included as measures of social self-esteem, while orderliness measures included the Order scales from the Personality Research Form and Comrey Personality Scales. Results from the multitrait-multimethod matrix and the multimethod factor analysis of data based on 93 males and 103 females provided strong evidence for the convergent and discriminant validity of the various trait measures.     

Effects of perception versus imagery on later recognition of visual patterns.

Three experiments were conducted to determine the role of imagery in aiding memory for visual information and to compare its effectiveness relative to direct perception. Subjects engaged in orienting tasks in which they had to decide whether the second of two sequentially presented meaningless patterns was a part of the first. They later received unexpected recognition tests for the original drawings. Increasing the interval between patterns by adding an extra post-stimulus period for imaginal processing improved later recognition scores. Experiments comparing continued perception with an equal blank interval suggested that periods of direct perception and of imagery are about equally effective in promoting memory. The results are discussed in the frame work of Craik and Lockhart (1972) with regard to type I and type II processing, and in the light of Neisser's (1967) view on imagery and perception.     

Taste-mediated potentiation of noningestional stimuli in rats

Holtzman rats drank saccharin in a distinctive environmental chamber prior to lithium-induced toxicosis. This treatment was administered four times. These animals subsequently drank less water or familiar saline in the chamber than animals which received water in the environment during conditioning. In addition, these environmental stimuli blocked the formation of a lithium-mediated coffee aversion more if they were conditioned in the presence of saccharin than if they were conditioned in the presence of water. Such differential blocking provided further evidence that the presence of a taste during conditioning facilitated aversion learning to the environmental chamber.     

The effect of punishment and reinforcement procedures on a stutterer's factor II avoidance response

The purpose of this clinical experiment was to investigate the manipulability of a Factor II avoidance response (arm movement). The substantive hypothesis under test was that its suppression would be enhanced by repeated punishment sessions. During the first of nine therapy sessions response-contingent negative stimulation was not delivered. In the next five, after a base-rate period, “wrong” was made consequent upon the target response. In each of these sessions the suppression of arm movement was apparent. However, the magnitude of the suppression decreased from session to session. Evidently, the continued use of punishment did not enhance suppression. Because of this finding procedural changes were introduced in the next three therapy sessions. Verbal praise was added as a consequence of increasingly stringent omission criteria and three consecutive units of praise led to time-out from the reportedly fatiguing task of continuous speech. A marked reduction and then complete extinction resulted. Moreover, learning was evidenced since the frequency of arm movement lessened in the base-rate period of each session.
