This bibliography consists of clinical, experimental, and theoretical papers pertaining to the onset, development, and treatment of stuttering in children five- years old and younger. It is a downward extension of Silverman, F.H., Bibliography of literature pertaining to stuttering in elementary-school children, Journal of Fluency Disorders, 1978, 3, 87–102.     

Film-facilitated arousal and prosocial behavior

The present investigation sought to test the applicability of the excitation transfer model (P. Tannenbaum & D. Zillmann. In L. Berkowitz, Ed., Advances in experimental social psychology, Vol. 8, New York: Academic Press 1975) to prosocial behavior. This model predicts that for individuals predisposed to act prosocially, arousal transferred from an unrelated source will facilitate such behavior. Two studies were conducted in which male college students, treated in either a positive or neutral manner and shown an arousing erotic or nonarousing control film, ostensibly rewarded and punished a confederate for performance on a memory task. Contrary to predictions, the first experiment found the arousing film increased reward regardless of treatment. In the second experiment, where the neutral treatment was given a more negative tone, the predicted interaction was found. Specifically, subjects treated in a positive manner and shown an arousing film were significantly more rewarding than were similarly treated subjects shown the nonarousing film. While type of film had no effect on neutral subjects' reward behavior, the arousing film did increase their punitive behavior. These results, coupled with physiological and self-report data, strongly support the excitation transfer model.     

The experience of self-awareness and its relation to level of self-consciousness: An experiential sampling study

The present research studied self-awareness by utilizing experiential sampling methodology, which allows for the random sampling of individuals' thoughts and feelings as they go about their normal daily activities. Neither Study 1 nor 2 found a relation between private or public self-awareness and negative affect. However, attention to private self-aspects was generally more positive and less ruminative for low as opposed to high private self-conscious subjects, and awareness of oneself as a social object was generally more positive but less important for low as opposed to high public self-conscious subjects. What may have accounted for the negative relation between private self-consciousness and average affect was that low private self-conscious subjects were more likely to attend to their private self-aspects if they were pleasant than if they were unpleasant, while high private self-conscious subjects' degree of private self-awareness was unrelated to whether the content of this state was pleasant or not. These findings are consistent with the hypothesis that low private self-conscious individuals engage in a more selective type of self-attention when in the private self-aware state than do high private self-conscious individuals. Regarding the relation between self-awareness and social context, both studies found that the presence of others results in a heightened public self-awareness. However, even though subjects were more attentive to public self-aspects when with others than when alone, in general, they were more attentive to their “private self” than to their “public self”. Results are discussed in terms of current self-awareness theory.     

Responding to indirect speech acts

Indirect speech acts, like the request Do you know the time?, have both a literal meaning, here “I ask you whether you know the time,” and an indirect meaning “I request you to tell me the time.” In this paper I outline a model of how listeners understand such speech acts and plan responses to them. The main proposals are these. The literal meaning of indirect speech acts can be intended to be taken seriously (along with the indirect meaning) or merely pro forma. In the first case listeners are expected to respond to both meanings, as in Yes, I do—it's six, but in the second case only to the indirect meaning, as in It's six. There are at least six sources of information listeners use in judging whether the literal meaning was intended seriously or pro forma, as well as whether there was intended to be any indirect meaning. These proposals were supported in five experiments in which ordinary requests for information were made by telephone of 950 local merchants.     

Methodological issues in language acquisition research with very young children

It is suggested that the dominance of observational methods in child language research with very young children has limited progress in understanding the language acquisition process. Evidence is presented that, contrary to popular belief, naturalistic methods do not guarantee ecological validity, nor are they free of task biases. Furthermore, observational studies do not necessarily provide better measures of linguistic competence than do more structured methods. Instead, it is argued that new insights from cognitive developmental research are applicable in studying language production in children younger than 3 years. A number of structured techniques are reviewed that have been used or could be used to study language production. It is concluded that a combination of methods is necessary in order to disentangle and control the many variables that enter into the language acquisition process.     

A developmental study of pronouncing responses in the discrimination learning of words and pictures

Subjects at three age levels were administered picture pair or word pair discrimination lists. They pronounced or pointed as a method of choice, and they pronounced or pointed at the correct item (or remained silent) during rehearsal. The results indicated that with picture pairs, pronunciation facilitated learning as a method of choice and a type of rehearsal in nursery school Ss. For fifth grade and college Ss, there was no significant difference between pronouncing and pointing as a method of choice. However, spoken rehearsal was superior to control performance for fifth grade Ss. College Ss performed equally well in the control and pronouncing conditions, but pointing during rehearsal produced significantly more errors than pronouncing. Word pairs produced no significant pronunciation effects. These results were discussed within an internalization of speech perspective.     

The smoked plastic screen: An alternative to the one-way mirror

A double thickness, smoked plastic screen is presented as an alternative to the one-way mirror. Relative to the glass mirror, the use of the plastic screen provides a safe, nondistracting, durable, light weight, and inexpensive method for unobserved viewing without an appreciable loss in light transmission.     

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.     

Dominance as a function of cue similarity: A test of the intrinsic cue dominance model

A nonselective model postulating intrinsic cue dominance was tested in simultaneous discrimination tasks involving reversal on one dimension. In this procedure two dimensions are relevant throughout training; however, following initial discrimination training the reward contingency is reversed for one dimension but maintained for the other. Cue dominance was assessed following acquisition of reversal by the use of opposed-cues test trials, and was defined as a greater number of choices of the test compound containing the positive cue of the reversed dimension than of the test compound containing the positive cue of the maintained dimension. In Experiment I, brightness cues dominated orientation cues. In Experiment II, which employed two different sets of relevant cues, more disparate brightness cues dominated the orientation cues for one set and orientation cues dominated less disparate brightness cues for the other. From this, it was concluded that dominance is a function of relative cue similarity.     

Relation of the verbal transformation and the phonemic restoration effects

This study examined the relationship between illusory changes of repeated words (“verbal transformations” or VTs) and illusory presence of phonemes replaced by noise (“phonemic restorations” or PhRs). Separate groups of 20 subjects were each presented with one of four taped variations of the repeated stimulus word “magistrate”: stimulus intact (MAGISTRATE); speech sound “s” removed and replaced with a silent gap (MAGI TRATE); speech sound “s” removed and replaced with a louder extraneous sound (MAGI¹TRATE); syllable “gis” removed and replaced with a louder extraneous sound (MA⁷¹TRATE). The stimuli MAGI¹TRATE and MA⁷¹TRATE evoked PhRs, and with these stimuli, the phonetic changes corresponding to VTs were concentrated at the perceptually restored portions of the word. It is suggested that both PhRs and VTs are related directly to perceptual processes employed normally for the correction of errors and resolution of ambiguities in speech. Other effects of PhRs upon VTs are described and implications of these findings for mechanisms underlying speech perception are discussed.     

Interaction of reinforcement conditions and developmental level in a two-choice discrimination task with children

A total of 540 first, fourth, and eighth graders, equally divided by sex, were run on a two-choice discrimination task under one of three reinforcement conditions: reward (R) for correct responses, punishment (P) for incorrect responses, or reward and punishment (RP) for correct and incorrect responses. Half the Ss were tested by a male E; half, by a female E. Across all developmental levels, learning was superior in the P group. Complex interactions involving sex of S and E underline the importance of organismic variables in discrimination learning and in specifying parameters of reinforcer effectiveness.     

The effects of dynamic assessment procedures on Raven Matrices performance,visual search behavior,test anxiety and test orientation

The effects of dynamic testing procedures on Raven Coloured Matrices performance, visual scanning procedures, test anxiety, and orientation to the test situation were assessed. The subjects were 72 third-grade children. The results supported the hypotheses of the study showing that (1) dynamic assessment procedures involving either verbalization or elaborated feedback lead to higher levels of Raven Matrices performance; that (2) dynamic assessment modifies visual search behaviors; and that (3) dynamic assessment reduces test anxiety and negative orientation to the testing situation. The results are interpreted as offering construct validation to the assessment approaches used.     

The effects of empathy and outcome on attribution: An examination of the divergent-perspectives hypothesis

Based on the theoretical ideas of Jones and Nisbett (Jones et al. Attribution: Perceiving the cause of behavior. New York: General Learning Press, 1971), and the recent findings of Regan and Totten (Journal of Personality and Social Psychology, 32, 1975, 850–856), the present study assumed that from an attributional standpoint empathic observers and actors are functionally equivalent. On this basis it was predicted that empathic, relative to nonempathic, observers would make outcome attributions which have been typically found for actors themselves: They would attribute an actor's success to dispositional causes, but an actor's failure to situational causes. After instructions to empathize with the target, or to observe him, subjects watched a videotape of a target male attempting to make a good first impression on a female. Subjects later learned that the target had either succeeded or failed at making a good first impression, and were asked to make causal attributions for his outcome. As predicted, instructions to empathize led to dispositional attributions for success and situational attributions for failure, while standard observation instructions resulted in dispositional causal attributions regardless of outcome. The results were interpreted as supporting the contention that differential information processing may sufficiently account for the effects of outcome on causal attributions.     

The effects of task and practice on search for invisibly displaced objects

The ability to successfully search for an invisibly displaced object is frequently assumed to relate to the emergence of mental representation at around 2 years of age. However, little is known about what is actually being measured in the typical “stage 6” object permanence search task. Two studies examined the effects of task factors and practice on invisible displacements and systematic search tasks to show that simple variations in ways of hiding an object change the child's ability to find it. Experiment 1 compared two common methods of presenting invisible displacements items to 36 children, approximately 2 years of age. One task was significantly easier than the other, despite the fact that they contained identical items that varied only in their order of presentation. Experiment 2 tested the effects of short-term practice on 18- and 24-month-olds' success on invisible displacements trials and on two systematic search tasks. Results indicate that too little practice inhibited performance in 18-month-olds, but that practice beyond an optimum level did not further affect their scores. In contrast, 24-month-olds continued to benefit from increased practice until they reached the maximum possible score. The findings are interpreted to mean that invisible displacements tasks may require only sensorimotor search strategies rather than representation. The findings also have implications for (a) research that attempts to relate object permanence to other variables and (b) programs that use object permanence as an assessment or screening measure.
