Outcome predictors in the behavioral treatment of stuttering

The MMPI and subscales of the Stuttering Severity scale were utilized to predict motivation and success in the behavioral treatment of 32 stutterers. Subjects spent a mean of 10 individual sessions in criterion-oriented learning of fluent speech based on speech-muscle relaxation aided by EMG visual biofeedback. Judged motivation and judged success were strongly related to each other and significantly related to MMPI K and Es scores and negatively to F and Sc. Actual success was negatively related to Sc and Pd, completely unrelated to Es, and (if anything) negatively related to K. Results are consistent with previous studies, and show that global judgements of progress were only minimally related to a measure of actual progress.     

Semantic and surface codes in the memory of deaf children

In three experiments, deaf children in the age range of 6 years, 10 months to 15 years, 5 months were presented with continuous lists of items, and for each item they had to indicate whether it had appeared before on the list. Later items were related to preceding items either in surface form or in meaning or were unrelated. False-recognition errors (i.e., “yes” responses to new items) served as an index of memorial coding. In one experiment, the items presented to the subjects were printed words. The results of this experiment showed a false-recognition effect (i.e., more errors to related words than to unrelated words) for both semantically related words and orthographically similar words. In the other two experiments, the subjects viewed a series of manual signs on videotape. In these experiments, there was a false-recognition effect for signs related semantically and for signs related cherologically (i.e., similar in terms of their manual production). These results establish orthography and cherology as effective memorial codes for deaf children. The finding of a consistently strong semantic effect for young deaf children stands in contrast to findings of weak semantic effects in false-recognition studies with young hearing children. The ascendancy of semantic codes for deaf children was attributed to the absence of competition from the speech code which dominates the linguistic memory of hearing children.     

The generality of learned helplessness in the rat

Two experiments were simultaneously conducted in which two different groups of 40 rats each were exposed to one of two different stressors. In both experiments half the subjects were pretreated with shock, half with underwater exposure. For each pretreatment stressor, half the subjects were allowed to escape, the other half were not. The experiments differed in the test task used. Approximately 24 hr after pretreatment, one-half the subjects from each pretreatment group received 20 water-escape trials in an underwater maze, the other half received 20 shock-escape trials in a two-way shuttle box. The subjects in each of the inescapable pretreatment conditions were slower to escape in the subsequent shock-escape and water-escape tasks when compared with subjects in the corresponding escapable pretreatment condition. The “learned helplessness” effect appeared to be no smaller when aversive stimuli were changed between pretreatment and test than when they remained the same.     

Relationship of self-concept and vocational maturity to vocational preferences of adolescents

This study investigated the differences in vocational attitude maturity and self-concept among Holland's six vocational categories. Data regarding self-concept, vocational attitude maturity, and vocational preference were gathered from 846 students randomly selected from grades 8–12 in an urban school system. An analysis of variance supported the research hypotheses: (1) There were significant differences in vocational attitude maturity among students in the six vocational categories; (2) there were significant differences in self-concept among students in the six vocational categories; (3) there was a significant relationship between vocational attitude maturity and self-concept among students in specific vocational categories.     

Effect of Diagnosis and Personality on Impression Formation1

Nurses were asked to rate patients differing in diagnosis and personality type. Two diagnosis conditions (psychogenic or physiogenic) were compared across two personality conditions: Mr. Cummings, a hypothetical patient presented to nurse/subjects via audiotape, willingly disclosed information about his illness in a nonemotional manner; while Mr. Lockwood, the second “patient”, disclosed less and was more emotional. Two control conditions were also included: One measured subjects' reactions to the personality type independent of diagnostic label; the second determined nurses' stereotypic reactions to the two diagnostic labels alone. Subjects reacted more favorably to Mr. Cummings than to Mr. Lockwood regardless of Cummings' diagnosis. Nurses' impressions of Mr. Lockwood, on the other hand, varied as a function of his diagnosis.     

INCREASING EXTENDED CARE FACILITY RESIDENTS' ATTENDANCE AT RECREATIONAL ACTIVITIES WITH CONVENIENT LOCATIONS AND PERSONAL INVITATIONS1

Residents of extended care facilities generally exhibit a low level of attendance at recreational and therapeutic activities. Spatial arrangement of rooms, prompting, snacks, and small prizes have been suggested as factors that affect attendance. The present study examined the effects of an extensive system of prompts and the location of activity areas on the attendance of residents at a variety of activities. Twenty-six subjects were randomly selected from the ambulatory population of the facility. The first time each subject entered the activity room during the first 6 min of an activity session their name was recorded. Reliability measures were taken at 10 sessions, with a 95% mean agreement between observers. The variables examined were the amount of individualization of subjects (experimental group I: names announced versus experimental group 2: names not announced), room location (central or peripheral), use of names in announcements (activity only versus activity and group I names), and mode of announcement (PA system only versus PA system and in-person). A counter-balanced group design with repeated measures was used, with a randomly determined order of application of experimental treatments. An analysis of variance split plot 2.222 (Kirk, R. E. Experimental Design: Procedures for the Behavioral Science. Belmont, Ca.: Brooks-Cole, 1968.) of the level of subject attendance yielded significant main effects for room location, F(1, 24) = 5.47, p < 0.05, and type of announcement, F(1, 24) = 9.10, p < 0.01, and significant interactions for Individualization × Use of Names in Announcements, F(1, 24) = 5.57, p < 0.05, and Room Location × Mode of Announcement, F(1, 24) = 7.90, p < 0.01. The results indicate that using a centrally located room and announcement of resident names increases attendance at a variety of activities. The increased social and environmental interaction generated by activity attendance has potential therapeutic benefits for the residents involved. Furthermore, the kind of information reported here and by others should be taken into consideration by planners of a variety of group living facilities, ranging from nursing homes to residential treatment cottages.
