The stutterer's reaction to the telephone as a speaking situation

A review of the literature indicates that one of the most commonly feared talking situations among stutterers is speaking on the telephone. One hundred-thirty stutterers who feared speaking on the telephone were interviewed regarding their fear of telephone calling and answering, the age at which they began to fear calling and answering, and their fear reactions to eight specific telephone calling situations.Data was analyzed for all subjects, male/female, black/white, and mild/moderate/ severe stuttering groups. Analysis indicated that telephone calling was judged to be more feared than telephone answering with the exception of the black stutterers. Acquisition of fear of the telephone occured earlier for telephone answering than for calling within most subgroups. When general reactions to the eight telephone situations were considered, the black stutterers had the most severe fear reactions while the male and moderate stutterers had the least severe reactions.     

Structuring decision problems and the ‘bias heuristic’

This paper examines our understanding of the decomposition of immediate acts when structuring decision problems. Seven different types of uncertainties are identified, and four of these are shown to be taken explicitly into account in models within the province of decision theory, described in terms of four interlocking systems interfaced with semantic memory (a core act-event system, and systems buffering utilities, probabilities and events, respectively). Requisite decision modeling is shown to require that the remaining three types of uncertainty (procedural uncertainty; how the decision maker will feel about subsequent acts; agency for changing subsequent states of the world) are also resolved. Methods for ‘fixing’ structure are discussed in terms of aiming at a common understanding about the ‘small world’ in which a decision problem is located. Difficulties in resolving uncertainties in doing this are described. An alternative approach, common in studies invoking ‘behavioural decision theory’ is contrasted: imposing structure, assuming common understanding. The latter approach is shown to involve (i) the ‘naturalisation’ of the small world in which the decision problem is located, and (ii) the utilisation of normative models as ‘ideal types’, leading to the use of the ‘bias’ argument in discussing subjects' performance in decision tasks. Using this argument reflexively, the operation of the ‘bias heuristic’ is identified in a survey of published papers referencing this approach to the study of decision making. Effects identified are: availability of tasks, subjects and explanations; representativeness of findings; and anchoring and adjustment of explanations. Implications for practice are discussed throughout the paper.     

Task-hemispheric integrity in dual task performance

A condition of task hemispheric integrity is predicted to result in a dual task situation when the central processing and response components of each task are associated exclusively with a given cerebral hemisphere. The prediction that this condition will generate more efficient time-sharing is tested in a series of four experiments. In experiment 1 the prediction is confirmed when a spatial (tracking) and verbal (letter memory search) task are time-shared, and the hand assignment to task responses is manipulated. In experiment 2 a spatial variant of the memory search is used instead of the verbal letter search, and hand assignment effects are not obtained, since when two spatial tasks are time-shared an integrity assignment is impossible. Experiment 3 validates the hemispheric lateralization of the two single task variants of the memory search task, while experiment 4 establishes the separate “spatial’ and “verbal” resource demands of the two variants by observing their differential interference with concurrent spatial and verbal tasks.     

The development of career choices: The relationship between patterns of commitment and career outcomes in adulthood

This study was designed to examine the theoretically predicted adult career outcomes of individuals who engage in different developmental patterns of commitment to choice. It was hypothesized, based on D. E. Super's formulations, that those who engage in increasing commitment and who do not revert to earlier behaviors would experience the most desirable outcomes in adulthood. This hypothesis was tested using an analysis of longitudinal data in relation to career outcomes at two points in adulthood. Minimal support for the hypothesis was found in combination with some findings to suggest that developmental patterns of increasing commitment may not lead to the predicted desirable outcomes. Implications for theory revision and future research are discussed.     

The holophrastic hypothesis: Conceptual and empirical issues

A conceptual distinction is drawn between a structural and a functional version of the holophrastic hypothesis. The structural version of this hypothesis views the single-word utterances of children as implicit expressions of either syntactic or semantic structural relations, while the functional version views each of these utterances as consisting of a single lexical item which is used for a particular communicative function. The arguments which have been proposed in favour of these two versions of the hypothesis are critically examined in the light of the empirical evidence which is currently available. It is concluded that this evidence only supports the functional version of the holophrastic hypothesis, there being no evidence available to support the interpretation of children's single-word utterances as implicit expressions of either syntactic or semantic relations.     

The effects of pacing and masking on stutterers' and nonstutterers' speech initiation times

The present study was undertaken to determine whether pacing and masking would facilitate improved speech initiation times (SITs) both for stutterers and for nonstutterers. All subjects were tested in control, pacing, and masking conditions. The results showed that both stutterers and nonstutterers (1) improved their SITs during the pacing condition as compared with the control condition (p = 0.01), (2) had slower SITs in the masking condition as compared with the control condition (p = 0.05), and (3) had faster SITs during the pacing as compared with the masking condition (p = 0.01). The SIT between-group findings demonstrated that stutterers were slower than nonstutterers across all SIT conditions (p = 0.08). The discussion of these results centers on the facilatory nature of novel stimulation in modifying speech-system functioning.     

Disfluency characteristics of 2-, 4-, and 6- yr-old males

Fluency characteristics of 36 nonstuttering males aged 2, 4, and 6 yr are presented in terms of patterns of disfluency and relationships among disfluency variables. The most frequently occuring disfluency types at each age level were revision-incomplete phrase and interjections; the least noted type was part-word repetitions for 2- and 4-yr olds and disrhythmic phonations for 6-yr-olds. Patterns of disfluency appear to be similar at all age levels studied, except that the 2-yr-old pattern showed greater magnitudes in various disfluency types. A range exists in the relationships among individual disfluency types, from moderately strong relationships between, for example, revision-incomplete phrase and interjections to lack of linear relationships between, for example, interjections and phrase repetitions. A linguistic factor may be strong within certain disfluency types. e.g., revision-incomplete phrase, interjections, and word repetitions, whereas a motor factor may be operative in others, e.g., part-word repetitions and disrhythmic phonations.     

Nonspecific elements in therapy with stutterers

Currently, many different strategies are employed by respected professionals working in the area of therapy for persons who stutter. This phenomenon serves as a point of departure for reflections on the nonspecific elements involved in therapy. Drawing on the literature of holistic medicine and psychotherapy these elements are identified as follows: (1) active participation of the client in the therapy process; (2) role of self-management skills; (3) influence of client's expectations regarding treatment; (4) suggestion as a factor in therapy; and (5) the therapeutic relationship.     

Disfluent speech associated with brain damage

The frequency and type of disfluencies in the spontaneous speech of 15 people with Broca's aphasia and right hemiplegia was studied. Two aged-matched control groups (15 nonaphasic stroke patients with left hemiplegia and 15 normals) were also studied. The frequency of disfluencies in the speech of aphasics was three times greater than that in the speech of either control group. However, most of the disfluencies uttered by aphasics were of the types commonly found in speech of normals.     

Vocal and nonvocal discriminative performance in monkeys

Discriminative performance of a lever press and a vocal call was compared in five macaques. The animals exhibited similar scores for Response Rate, Efficiency, and Error Index. Total vocal responses were slightly higher than total lever responses. Latency for vocal responses was significantly greater than lever press. Similar scores in measures of performance of the two behaviors indicate that discriminative vocalization is not exceedingly difficult. Failure by others to achieve discriminative vocalization in studies employing weak positive-reinforcement contingencies suggest that certain experimental paradigms are unsatisfactory for vocal conditioning.
