Flute stuttering

A case is reported of a stutterer who exhibited stuttering-like behavior while playing the flute in a highly competitive school orchestra. Theoretical implications are discussed.     

Interactive presentation in multitrial free recall

This paper explores whether free recall performance and organization can be facilitated using computer-controlled interactive presentation, where stimulus presentation on Trial N+1 depends on the individual subject’s prior recall history. A series of experiments investigated the effects of two types of response-contingent presentation order manipulations and of selective tagging manipulation designed to highlight the presentation of previously nonrecalled items. An initial experiment using 20-word lists showed no differences among groups, due to a ceiling effect. Two subsequent experiments, using longer lists (30 and 40 words), found that recall and subjective organization were increased by selective tagging and by presentation orders that preserved the subject’s prior order of recall. The results demonstrate that subjects’ previous recall histories contain information that can be used to facilitate recall. The potential of other interactive manipulations is discussed.     

The measurement of sleep onset latency in insomnia

Research into insomnia has relied almost exclusively upon subjects self-reports of sleep onset latency. The unreliability of self-reports have been repeatedly criticized yet despite the implementation of suggested changes substantial weaknesses remain. This study of 17 insomniacs outlines the development of a simple electrochemical device designed to yield objective estimates of sleep onset latency and compares this with independent estimates made by patients and their partners. The application of this device and the implications for the continued use of self-report measures are discussed.     

The Use of Progressive Relaxation and Hypnosis in Counselling Secondary-School Pupils

Counselling methods involving progressive relaxation and hypnosis are sometimes regarded as being mysterious and alarmingly innovatory, particularly within the context of the secondary-school system. The implications for counselling practice of the use of such methods are considered. Some ways in which they have been used to help young people of secondary-school age are outlined. A number of illustrative case-studies are given, and a relatively unsuccessful case-study is included.     

Stability of performances of individual stutterers on oral reading adaptation tasks

This study aimed to determine whether individual oral reading adaptation task performances are sufficiently reliable to be used as predictive indicators of improvement in stuttering behavior by testing the stability of individual stutterers' adaptation scores. Results demonstrated that all stutterers are not stable in their individual adaptation scores and therefore individual adaptation scores may be insufficiently reliable for predicting and classifying. Theoretical and clinical implications are discussed.     

Bibliography of literature pertaining to the onset,development, and treatment of stuttering during the preschool years

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.     

Personal memories at different ages

Men and women aged between 25 and 75 were asked to associate personal experiences to a set of 50 randomly chosen common words. The dates of these experiences were reconstructed and plotted as frequency distributions. Neither sex differences nor introversion--extraversion had reliable effects, and response latencies did not differ between conditions, but age differences significantly affected the memory distributions. Contrary to the hypothesis that ageing produces a selective deficit for recency, it appears that the average date of remembered events tends to increase with age.     

Rats learn the relationship between responding and environmental events: An expansion of the learned helplessness hypothesis

Previous research has shown that preexposure to inescapable shock interferes with subsequent acquisition of escape responding, while pretraining with escapable shock facilitates subsequent acquisition of a different escape response. It has also been demonstrated that interference and facilitation persist when the aversive event is changed between the two phases of training. The present experiment extended these findings, showing generalized learning from an appetitive to an aversive situation. Six groups of rats received the following treatment in the presence of discriminative stimuli: One group was trained to nose press for food, a second to chain pull for food, and a third to chain pull to escape or avoid shock. Two groups received either signalled free food or inescapable shock, and a naive control group received no pretreatment. All groups were then tested in a nose-press escape-avoidance situation. The three groups with prior response training acquired responding most rapidly, and at the same rate. The naive controls acquired responding slowly, and the two groups with response-independent histories did not acquire responding during the 5 days of training. It was concluded that rats learn the relationship between responding and environmental events and that such learning strongly influences subsequent learning.
