Sex differences in the structure of intelligence: A confirmatory factor analysis

The LISREL model of Jöreskog and Sörbom was used to perform a comparative factor analysis on intelligence data from four sex by generation groups. The covariance matrices for 10 psychometric ability measures were used to isolate Spatial and Verbal Intelligence factors. Results from a series of factor analysis models indicated substantial invariance in the factor pattern and factor covariance matrices, although the hypothesis of complete invariance in factor pattern was rejected. The groups did differ in observed and unique variances. The results were basically consistent with the hypothesis that males and females have similar intellectual structure, which would have been obscured had standardized factor analysis been employed. There were also sex and generation differences in the Spatial and Verbal factor means.     

A disfluency descriptor digest for clinical use

A clinical form to be used in identifying which of a set of fluency eliciting techniques might be used most advantageously in therapy with individual stutterers is described.     

A note on remembering to execute planned actions

The purpose of this article is to call attention to the necessary role of remembering in the execution of planned actions, such as following instructions, delivering messages, and keeping appointments. Remembering in this context is considered within a theoretical framework of activities, actions, and operations advanced by Soviet developmental psychologists. The importance of remembering planned actions in applied settings, strategies employed by children and adults in remembering planned actions, relationships between motivation and remembering, and developmental relationships are discussed. In addition, several characteristics of the Soviet developmental approach are briefly noted.     

The effects of induced affective states on letter discrimination in disadvantaged preschool children

The relationship between affective state and academic performance was examined using 30 4- to 6- year old economically disadvantaged black children. Children were assigned to one of three affective induction groups: positive, negative, or neutral affect. Changes from pre- to posttest administrations of a letter discrimination task suggest that negative and positive affect inductions produce different changes in both errors and response latency. These findings suggest that further research on the possibility that negative affect may be responsible in part for the academic difficulties of disadvantaged children and other children under stress is warranted.     

Vocal changes in stutterers and nonstutterers during monotoned speech

For years, reports have circulated that stutterers experience marked decrements in their stuttering when they speak or read in monotone. Wingate has suggested that the ameliorative effects of various novel speaking conditions on stuttering can be attributed to modifications in vocalization induced by such conditions. The present study was conducted to see whether this explanation would extend to monotoned speech as well. Ten teenage and adult stutterers and 10 normal speakers were tested in control and monotone reading conditions. Dependent measures were the frequencies of disfluency and stuttering, fundamental frequency, fundamental frequency standard deviation, vocal SPL, vocal SPL standard deviation, and fluent reading rate. Only within-group statistical comparisons were made, because members of the two groups could not be matched pairwise along critical vocal parameters. The major findings of this study indicated that across the two conditions, both groups significantly reduced their fundamental frequency, fundamental frequency standard deviation, vocal SPL and vocal SPL standard deviation. Only the stutterers exhibited a significant decrement in disfluency and stuttering. The normals did not evince enough disfluency in the control condition for a reduction to occur during monotoning. Neither group effected a reduction in fluent reading rates. These and other findings and interpretations are discussed relative to Wingate's modified vocalization hypothesis.     

Word frequency and children's stuttering: The relationship to sentence structure

This study investigated the relationship between word-frequency level and stuttering within the context of four slected sentence types. Fifteen stuttering children, aged 8–12, read 48 sentences of four different transformational types, and three word-frequency levels 12 simple active-affirmative-declarative (SAAD), 12 negative, 12 passive and 12 negative-passive. All sentences were identical in terms of underlying swings and variations of the SAAD sentences. Results agreed with Ronson's study with adults (1976) in that when the group rating was severe and the sentence type was negative, stuttering increased significantly as word-frequency level decreased. It appears that children's stuttering in relationship to word-frequency level is a different response that is subject to variables of sentence type and the severity rating of stuttering.     

Cognitive and behavioral self-control strategies: Applications for the clinical management of adult stutterers

A model of therapy for adult stutterers which emphasizes the role of cognition in mediating the conditions for behavioral change is described. The philosophy of the program along with the specific forms and effects of several self-control strategies are discussed in relation to: (1) expectancy formation and the attainment of goals; (2) speech modification procedures; (3) transference of clinical gains; and (4) assessment of results. The use of cognitive restructuring procedures, self-instructional strategies, imagery and other coping skills for the management of speech-related stress is outlined. The importance of developing self-management and self-monitoring programs that clients may use in ongoing confrontations with real-life problems is emphasized in defining responsible behavior and the responsibility for change.     

Early position and stuttering occurrence

Early sentence position is one of several features of verbal expression frequently reported to be associated with stuttering occurrence. Some studies also have reported the concurrence of these features with normal disfluencies. A review of the pertinent literature reveals that, among these features, early position is associated significantly more often with stuttering than with normal dysfluencies. Results of a study investigating stress patterns in the fluent utterances of stuttering and normal speakers yielded contrasts which speak pointedly to the relationship between early position and stuttering occurrence.     

Effects of sexual versus fear arousal on alcohol consumption in college males

To compare the effects of pleasant and aversive arousal on alcohol consumption, 18 male undergraduates had three weekly sessions to separately view erotic, mutilation or neutral slides in a simulated memory experiment. Following exposure to the slides, they received access to alcoholic and nonalcoholic beverages, which were presented to half the subjects in a taste rating task, and to half as the result of engaging in an operant lever-press task. Subjects believed these tasks to be distractors during a purported retention interval. Self-report instruments and basal skin conductance confirmed the success of the affective manipulations. However, only the subjects using the taste task after viewing erotic slides significantly increased alcohol consumption. These results question a tension reduction model of drinking and qualify the contribution of autonomic arousal to motivation for drinking.     

Very long term memory for tacit knowledge

Very long term memory for abstract materials was examined by recalling subjects who had served in a synthetic grammar learning experiment two years earlier. In that study (Reber & Allen, 1978) we differentiated among several cognitive modes of acquisition, their resultant memorial representations, and their associated decision processes. Two years later and without any opportunity for rehearsal or relearning, subjects still retain knowledge of these grammars to a remarkable degree. Although some differences have become blurred with the passage of time, the form and structure of that knowledge and the manner in which it is put to use remain strikingly similar to the original. That is, differences traceable to acquisition mode and conditions of initial training can still be observed. As in the original study, these results are discussed within the general context of a functionalist approach to complex cognitive processes.
