Speech—Language clinicians'' and university students'' impressions of women and girls who stutter

To identify impressions speech—language clinicians and university students have of females who stutter, a 47-scale semantic differential form was administered to members of each group to obtain their responses to eight hypothetical constructs, i.e., “A Girl,” “A Girl Who Stutters,” “A Boy,” “A Boy Who Stutters,” “A Woman,” “A Woman Who Stutters,” “A Man,” and “A Man Who Stutters.” Both groups were found to possess negative stereotypes for all four categories of stutterers. The nature of the stereotypes appeared to be influenced by a stutterer's gender and relative age. Clinicians considered stuttering to exert a stronger negative impact on females and on children. Their strongest stereotype was of “A Girl Who Stutters.” University students considered stuttering to exert a stronger negative impact on males. Their stereotypes of stutterers seemed unaffected by the relative age of the stutterer. Their strongest stereotype was of “A Man Who Stutters.” Several theoretical and clinical implications of these findings are discussed.     

The pitch of “real” and “rhetorical” questions directed by a father to his daughter: A longitudinal case study

A longitudinal study of a father and his daughter examined pitch-variation of “real” and “rhetorical” questions. Although the father asked “real” and “rhetorical” questions from the start of the recordings, he did not distinguish them through differential pitch height until the baby was 15 months old.     

A thematic coding system for the intimacy motive

A new thematic (TAT) measure of intimacy motivation was developed and cross-validated in four separate arousal studies using three different college populations. A brief sketch of the derived thematic scoring system for intimacy motivation was presented. The goal state of the intimacy motive was defined as experiencing a warm, close, and communicative exchange with another person. In a college sample, subjects scoring high on the intimacy motive were rated by friends and acquaintances as significantly more “warm,” “natural,” “sincere,” “loving,” and “appreciative” and less “dominant,” “outspoken,” and “self-centered” than subjects scoring lower. The results were discussed in terms of the theories of Sullivan on the need for interpersonal intimacy, Maslow on growth motivation and “B-love,” Bakan on communion, and Buber on the I-Thou relation. Differences between the new coding system and the need for Affiliation (n Aff) system for scoring imaginative productions were also suggested.     

A comparison between “aware” and “naive” conditions in the suppression of GSR activity

“Aware” (A) and “naive” (N) groups received different instructional sets, the former being informed both of the nature of their task and the response-reinforcement contingency. Negative reinforcement was given to these groups whenever a spontaneous GSR was emitted during four 4-min trial periods. Two corresponding yoked-control groups, CA and CN, received non-contingent reinforcement over the same periods. The contingent reinforcement groups both showed learned suppression of spontaneous GSR activity, but comparison between the A and N groups revealed a significant interaction between Time and Instructional Set. It is suggested that the “aware” instructional set had an inhibitory effect upon learning.     

Part of speech and phonological form implied in written-word comprehension: Evidence from homograph disambiguation by normal and aphasic subjects

A sentence construction experiment examining the effect of part of speech and phonological form in written-word comprehension is reported. Normal and aphasic subjects had to write sentences incorporating a given word pair, one word was a homograph (e.g., “bank”) whose meaning was context-biased by the other (e.g., “money”/“river”). The effect of three psycholinguistic factors on subjects' performance was questioned: (i) The relative frequency of one meaning of the homograph as compared to the other meaning; (ii) The lexical/syntactic ambiguity (“ball”/“can”); (iii) The same/different phonological forms of the two meanings (“fair”/“bass”). The results are discussed in the framework of a model in which multiple special-purpose procedures are involved in normal processing, some of them being differentially impaired by brain disease in Broca's and Wernicke's aphasics.     

Increasing Behavioral Skills and Level of Understanding in Adults: A Brief Method Integrating Dennison's Brain Gym & #x00AE; Balance with Piaget's Reflective Processes

A single session intervention was given individually to 4 adults in order to assist them in achieving their personal goals by improving their behavioral skills for achieving the goals and their conceptual understanding of & #x201C;how to & #x201D; attain these goals. The method was based on a brain-ability analysis of understanding & #x201C;conservation & #x201D; on Jean Piaget's conservation tasks combined with Paul and Gail Dennison's Brain Gym & #x201C;balance & #x201D; procedure. My & #x201C;whole brain understanding & #x201D; model (C. A. Wolfsont, 1999, 2000) and M. L. Commons et al.'s Hierarchical Complexity Scoring System manual were used to analyze the verbal protocols (M. L. Commons et al., 1992; Commons, Danaher, & Meaney, 2000). Increases were found in the participants' conceptual understanding and in the complexity of their performance.     

An improved technique for monitoring fixation in tachistoscopic tasks

A monocular lens mounted behind a stimulus screen was used to monitor fixation in a tachistoscopic recognition task. This technique was found superior to the often used “sideview technique” and as accurate as the method involving identification of a fixation stimulus. It was found that the “telescope technique” is preferable in those studies where presentation of a fixation stimulus might interfere with recognition or report of the experimental stimulus.     

Productive conflict in group decision making: genuine and contrived dissent as strategies to counteract biased information seeking

Decision-making groups in organizations are often expected to function as a “think tank” and to perform “reality testing” to detect the best alternative. A biased search for information supporting the group's favored alternative impairs a group's ability to fulfill these requirements. In a two-factorial experiment with 201 employees and managers from various economic and public organizations, genuine and contrived dissent were investigated as counterstrategies to biased information seeking. Genuine dissent was manipulated by forming three-person groups whose members either all favored the same alternative individually (homogeneous groups) or consisted of a minority and a majority faction with regard to their favored alternative (heterogeneous groups). Contrived dissent was varied by the use or nonuse of the “devil's advocacy” technique. The results demonstrate that heterogeneity was more effective in preventing a confirmatory information-seeking bias than devil's advocacy was. Confidence was identified as an important mediator. Implications for the design of interventions aimed at facilitating reality testing in group decision making are discussed.     

A reexamination of body build stereotypes

Using semantic differential and discriminant analysis techniques, the study sought to determine (a) the existence of body build stereotypes, (b) the extent of identification with these stereotypes, and (c) the effect of identification upon the child's self-evaluation. The subjects were 406 children in Grades four to eight from a midwestern community. All subjects were white and had predominantly middle-class backgrounds. Subjects completed the Piers-Harris Children's Self Concept Scale, semantic differential ratings of the Global self-concept, and the body build concepts of “SKINNY GIRL,” “FAT GIRL,” “SKINNY BOY,” and “FAT BOY,” and the situationally specific self-concepts of “MYSELF IN THE CLASSROOM,” “MYSELF AT LUNCH/RECESS,” and “MYSELF WHEN LOOKING IN A MIRROR,” Measures of weight and height were obtained using a standard weighing scale and wall chart. Fat child and skinny child stereotypes were found to be invariant across age and sex groups and did not appear to be gender specific. Actual fatness was found to be generally related to identification with the body build stereotypes, but not strongly so. Low self-esteem was a concomitant of identification with the fat child stereotype. The majority of children identified with the average child in all settings.     

Perceived Sources of Happiness: A Network Analysis

This study investigated the perceived sources of happiness among young men and women. Rank scores of the perceived reasons for happiness were compared between the two groups and seven significant differences were discerned. Men ranked “sexual activity”, “sports”, being “liked” and having a “good social life” significantly higher than women. Women ranked “helping others”, having a “close family” and being “loved by loved ones” significantly higher than men. A modified form of network analysis was also conducted. Both networks demonstrated similar core representations of happiness with a focus on self-confidence, being free of stress, occupational and social factors, family support and personal relationships. However, the networks show an association between sexual activity and male personal relationships, whereas emotional factors are associated with female personal relationships. The male network also demonstrates the importance of sports and physical activity in male happiness. Despite some gender differences, it is suggested that the similarities within the mean rank scores and networks form the core elements of a shared social representation of happiness.     

Point of view in personal memories

A structural aspect of personal memories was examined in four studies. In some memories, one has the perspective of an observer, seeing oneself “from the outside.” In other memories, one sees the scene from one's own perspective; the field of view in such memories corresponds to that of the original situation. The existence of “observer” and “field” memories was confirmed in Study 1, using a recall questionnaire. In Study 2, the similarity structure of a specified set of eight to-be-recalled situations was established: the significant dimensions were “emotionality” and “self-awareness.” Study 3 related these dimensions to the observer-field distinction; situations involving a high degree of emotion and selfawareness were most likely to be recalled with an observer perspective. Recall set was varied in Study 4: a focus on feelings (as opposed to objective circumstances) produced relatively more field memories. Studies 3 and 4 also showed that events reported as more recent tend to be recalled in the field mode. Thus a qualitative characteristic of personal memories—the perspective from which they are experienced—is apparently related to characteristics of the original event, to the individual's purpose in recalling that event, and to the reported recall interval.     

Interpersonal dominance and coronary prone behavior

Type A “coronary-prone behavior” is a risk factor for coronary artery and heart disease. Questionnaire research indicates that interpersonal dominance is one of the strongest behavioral correlates of the Type A behavior pattern, although little effort has been made to demonstrate a link between the behavioral manifestations of interpersonal dominance and Pattern A responding. This study was conducted to establish such a link. All possible combinations of extreme As (N = 42) and Bs (N = 42) were matched in dyads that negotiated extreme bipolar opposite positions on a “teacher dismissal” issue. Analysis of process and outcome behaviors suggested that type A individuals are unilaterally more dominant than their Type B counterparts. Possible physiological mechanisms mediating dominance and cardiovascular disease are discussed.     

Human variable ratio performance

The generality of the mathematical principles of reinforcement (MPR) was tested with humans. In Experiment 1A, participants’ mouse clicks were reinforced according to a series of variable-ratio (VR) values. In one condition, a situated task was used (searching for treasure on a map presented via a PC monitor); in the other, abstract version of the task, participants clicked on a white screen. Under the “map” condition, response rates increased with increasing ratio value before decreasing with further ratio increases; under the “no-map” condition, response rates decreased linearly from a peak at the smallest ratio. In Experiment 1B, the pattern of responding was confirmed under the “map” conditions using a different set of ratio values. In Experiment 2, reinforcer magnitude was manipulated using the “map” context. Response rates did not differ significantly when large rather than small cash reinforcers were delivered according to a VR 30 but were significantly higher when large rather than small cash reinforcers were delivered according to a VR 120. Together these experiments offer qualified support for extending MPR to the behavior of human participants.     

The effect of stimulus amplitude on the threshold of fusion of paired flashes

Four experiments are described in which the threshold of fusion of paired flashes was measured. The intensity of the single flashes making up the pairs was varied independently. The results showed that when the first flash of the pair was the more intense, the threshold of fusion increased linearly as the difference in the log intensity of the two flashes. A proposal put forward to explain the results suggested the “noise” created by the first flash of the pair has to dissipate to a critical extent to allow the “signal” arising from the second flash to be detected.     

Language in right-handers with right-hemisphere lesions: A preliminary study including anatomical, genetic, and social factors

A comprehensive test battery was devised to study the effects of right hemisphere lesions on the speech and language of “nonaphasic” dextrals. Data were thus obtained for 62 subjects, 20 of them neurologically healthy and 42 with a focal right hemisphere lesion resulting from a cerebro-vascular accident. A preliminary global analysis of these data is reported. Anomalies were observed in 33 brain-damaged subjects. Although discreet in all cases, these anomalies were shown to have various degrees of severity. Given the population submitted to this study, the subject most likely to show such anomalies was defined, genetically, as a right-handed adult with a family history of ambidextrality or left-handedness and, socially, as one with a relatively limited education. The implications of these findings are discussed together with the problem of the anatomo-clinical correlations of language disorders resulting from right hemisphere lesions in “nonaphasic” dextrals.     

Stimulus control in a simple instrumental task: The role of internal and external stimuli

Two experiments using rats in a straight alley runway task tested the hypothesis that standard stimuli such as tones and lights (“external” stimuli) and schedule-generated aftereffect stimuli (“internal” stimuli) operate similarly and are similarly subject to the compounding rules specified by R. A. Rescorla and A. R. Wagner (In A. Black & W. Prokasy (Eds.), Classical conditioning II: Current theory and research. New York: Appleton-Century-Crofts, 1972). The experimental task was an instrumental analog of the classic blocking experiment (L. J. Kamin, In M. R. Jones (Ed.). In Experiment 1, blocking of an external discriminative stimulus by a different asymptotic discrimination was accomplished. In Experiment 2, blocking of an internal stimulus discrimination by an asymptotic external stimulus discrimination was obtained. The present results support the view that internal and external stimuli are indeed similar and function in the same manner with regard to blocking of stimulus control.     

Are professors likely to report having “beliefs” about the intelligence and competence of students who stutter?

Some university students who stutter report that they avoid participating in class discussions and talking with professors because they believe that if their professors find out they stutter, the professors are likely to view the students as being less intelligent and/or competent than they otherwise would. The purpose of this study was to determine whether professors, as a group, are likely to report such beliefs. A random sample of 87 professors at Marquette University, Indiana University of Pennsylvania, and the State University of New York at Stonybrook rated “A Student Who Stutters” on each of 81 seven-point, bipolar semantic differential scales, including intelligent/unintelligent and competent/incompetent. Although there was considerable scatter in their ratings for the majority of the scales, 85 of the 87 rated the student at the center or “positive” end of the intelligent/unintelligent scale and 83 of the 87 did so on the competent/incompetent one. Assuming that the attitutes reported by the professors reflect their “real” ones, these data suggest that many—perhaps the majority—do not have negative attitudes about the intelligence and competence of their students who stutter.     

Residual reading capability in a patient with alexia without agraphia

A case of pure alexia due to an ischemic lesion of the occipital temporal region is described. Written words could be matched but not read. Immediate memory span for graphemes was defective. The reading defect probably depends on the inability to modify the written word “globally”; the phonological process was intact, but the memory disturbance impeded reading. The dissociation is explained by the preservation of word forms, which are linked to the semantic stage. Nonwritten stimuli trigger a “meaning” which evokes the word form and so the written word is recognized even though it cannot be read.     

Information processing by performers and observers in a paired associate learning task

The effects of two training procedures on learning and performance are compared. Performers select a response alternative for each stimulus on Trial 1 and receive feedback in terms of “Right” or “Wrong”. Observers receive the same information by listening to the experimenter. Experiment I tests the hypothesis that performers and observers are using a different learning strategy when there are only two response alternatives available for each stimulus on Trial 1. A recognition procedure was used on Trial 2; each stimulus was followed by four alternatives, two of them being the same as presented on Trial 1. Subjects have to recognize the two “old” alternatives. Performers are always better at recognizing the chosen alternative, whereas observers are better at recognizing the correct alternative. Experiment II extends the comparison between performers and observers to a task with four response alternatives on Trial 1. There are no longer differences in performance between the two training procedures.     

Food priming: A therapeutic tool to increase the percentage of meals bought by chronic mental patient

In a motivating ward environment for schizophrenics, three methods of maximizing food as an effective reinforcer were tested. On the basis of pre-treatment measures, patients were classified as (1) “non-chronic meal missers” who served as control patients (Group A), (2) “chronic meal missers” because they had no tokens (Group B), or (3) “chronic meal missers” because they chose not to eat but had tokens (Group C). One of the following three experimental treatments was then administered when a patient missed a meal : (1) visual food priming (observing others eat), (2) oral food priming (sampling one teaspoon of each type of food for that meal), and (3) free meal (being offered a free meal when it was missed). Oral and visual food priming were found to be equally effective in increasing the percentage of meals bought by patients. A post-treatment follow-up for Group B found that this increase was even greater during the follow-up phase. The percentage of meals bought by patients in the free meal condition of Group B decreased during the treatment phase but was significantly above pre-treatment measures during the follow-up phase, suggesting that complete reinforcer sampling may also be an effective technique for increasing the percentage of meals bought.
