Sign recall by hearing signers: Evidences of dual coding

Deaf participants' sign recall is affected by sign similarity, sign length, irrelevant signing and manual articulatory suppression, suggesting the existence of a phonological loop for signs. In two experiments we explore whether hearing signers (who have learned Spanish Sign Language as second language) use a phonological loop for signs, whether they use their phonological loop for words or whether they use both when recalling sign lists. Articulatory suppression (manual and vocal) and list similarity (word similarity and sign similarity) were manipulated in two experiments. Results clearly suggest that our participants recode orally the signs and use those representations to recall sign lists, but visuospatial information is also used in this task.     

Projective drawings and children who stutter

Five young stutterers (aged 5–10 yr) and a matched group of five nonstuttering children completed five projective drawings and a scale for assessing communication attitudes of children at the beginning and at the end of a 3-mo treatment period. While the attitude scale failed to indicate differences between stuttering and nonstuttering children, performances on selected drawings did distinguish between experimental and control subjects. In addition, significant changes were observed in selected drawings over the treatment period for the young stutterers.     

Perception of temporally competing speech stimuli in preschool children

The aim of this study was to investigate the perception of competing speech stimuli in 3-, 4-, and 5-year-old normally developing children. A dichotic listening paradigm was used in which the temporal alignment between the two stimuli was varied to represent three levels of competition. Minimal, moderate, and maximal levels of temporal competition were represented by a Separation, Lag, and Simultaneous test condition, respectively. The subjects were behaviorally set to listen for and to report the two stimuli on each trial. The incidence of double correct responses in the test conditions was the measure of interest. The results show a sharp and linear drop in double correct scores from the Separation, to the Lag, and to the Simultaneous condition. There were no age-related differences in the Separation and the Simultaneous conditions. In the Lag condition, the performance of the 3-year-olds was significantly lower than the 4- and 5-year-olds. The findings were interpreted to be indicative of limited auditory processing ability in preschoolers for moderately and maximally competing speech stimuli.     

Stutterer''s scaled attitudes and their prognostic significance in therapy

Thirty individuals who manifested stuttering behavior participated in an intensive therapy program. Measures of pretherapy attitudes on the Attitude and Behavioral Observation Scale, which consists of self-evaluations of attitudes on a scale of five equal-appearing intervals and also two questionnaires, the Iowa Scale of Attitude Toward Stuttering and the Stutterer's Self-Ratings of Reactions to Speech Situations were utilized. These three scales were found to be significantly correlated. A difference score from the Motor Performance Scale, a speech proficiency scale of one to five was completed at pre- and posttherapy, as a measure of the client's success from therapy. Generally, pretherapy attitudes did not correlate significantly with success from therapy.     

Cerebral dominance in aphasia recovery.

This investigation studied the patterns of ear preference of a group of 25 aphasic adults through the administration of two verbal dichotic tests and retests over a 2-month interval of time. These dichotic tests were a Dichotic Digits Test (DDT) and a Dichotic Animal Names Test (DANT). Schuell's short test of aphasia was given twice over this interval to assess language recovery. Results indicated that as aphasics improve in language, cerebral dominance becomes more firmly established in the right cerebral hemisphere. The data in this study tend to support a dominance shift hypothesis in the recovery of language after aphasia.     

Word-by-word analysis of observer agreement utilizing audio and audiovisual techniques

The purpose of this study was to compare audio and audiovisual techniques of analyzing stuttering behavior using a recently developed index of agreement (Young, 1975). Twenty speech pathologists identified moments of stuttering for ten adult stutterers using both audio and audiovisual methods. Although no statistically significant differences existed between the two conditions, the listeners had more difficulty identifying moments of stuttering during the audio condition when mild stutterers were used.     

Operant techniques used in stuttering therapy: A review

This article reviews research concerning the use of operant conditioning in stuttering therapy, and discusses the clinical implications of this literature. In order to be considered for this review, a report had to treat the findings of research specifically designed to use operant conditioning in the manipulation of speech disfluency. This body of experimental literature clearly indicates that operant management techniques can effectively reduce stuttering with punishment of disfluencies producing more notable results than reinforcement of fluent responses. Operant conditioning is an effective means of modifying stuttering behavior and should be more visible in terms of procedures used by speech therapists.     

Parental Narratives About Genetic Testing for Hearing Loss: A One Year Follow Up Study

Few studies examine whether and how parental attitudes towards genetic testing change over time. In this study we interviewed parents of 14 children with newly identified hearing loss at two time points: after referral to genetics and 1 year later. Qualitative analyses of parental narratives indicate that parental attitudes did not change significantly over this time. Parents who perceived genetic testing to be useful continued to value it after testing, while parents who did not perceive it as being useful for their child’s future held the same view a year later. The only parents who changed their views regarding the usefulness of genetic testing for hearing loss were those who reported that their children underwent significant changes in their hearing loss or were faced with other life threatening conditions. Parents were also often unaware of the role of the genetic counselor and how genetic counseling could help address many of their lingering questions and concerns. These emergent themes indicate the need for geneticists and genetic counselors to be aware of and sensitized to the questions and attitudes that bring parents to a genetic evaluation, as well as the reasons why parents may not follow up with genetic testing for hearing loss when recommended.     

The precision fluency shaping program: Replication and evaluation

The purpose of this article is to present the results of a two-year project to evaluate the Precision Fluency Shaping Program (Webster, 1980) in a community speech and hearing center. Fifty stutterers participated in therapy. Results indicated that Precision Fluency Shaping was an effective therapy for the treatment of stuttering. In addition, stutterer's perception of their speech changed from pre to post therapy. Follow-up data are presented on 28 clients. Advantages of conducting Precision Fluency Shaping, meeting accountability standards, and procedures for collecting follow-up data are discussed.
