Effect of audience reaction upon fluency rates of six stutterers

Each of six male stutterers spoke to a 14 member audience for 40 min. This speaking time was divided into eight 5-min periods during which several consequence conditions were in operation. Those consequence conditions consisted of various combinations of “good” and “stop” statements delivered by the audience following fluent and disfluent utterances, respectively. In one condition the speaker applied the consequences. It was found that while various combinations of consequences do not alter the total number of words spoken per minute, they affect the number of occasions of disfluences occuring per minute. It could not be determined which condition resulted in optimum rate changes. Suggestions are presented for maintaining fluent speech.     

The Selection of Trainees,Trainers, Facilities,and Meeting Times for In-Service Training for Teachers

If in-service training is to improve instruction, then careful planning must be done. The approach taken in assigning responsibility for the training, selection of trainees and trainers, provision of adequate facilities, and establishment of meeting times can have a tremendous influence on the success of the training.     

A deglitching circuit for the AA50 D/A converter

Switching transients or “glitches” are frequently encountered in signal processing applications involving digital-to-analog (D/A) conversion. A low-cost “deglitching” circuit is described and implemented for the Digital Equipment Corporation AA50 D/A converter option on the PDP-8/e minicomputer. Switching transients were eliminated using a noninverting, unity-gain sample-and-hold circuit (employing Datei System’s SHM-IC-1). Switching transients were reduced to below-noise levels across a wide range of output levels and sampling rates.     

A cognitive-behavioral perspective on intelligence

The present editorial has two purposes. The first purpose is to indicate a parallel trend in two seemingly disparate areas of research which upon closer examination have interesting possible ties. These research areas are information processing and cognitive-behavior modification (CBM). The second purpose is to highlight the role that affect plays in intellectual functioning, noting some of the implications which then follow for the assessment of intelligence.     

Pupillometric assessment of retrieval operations in factual long-term memory

The process involved in recall from long-term memory were studied through the use of a general knowledge questionnaire and the technique of pupillometry. Degree of processing of the components of the retrieval process was inferred from second-by-second monitoring of pupil size. Measurements were recorded during subjects' attempts to retrieve the answer to the query, or if unsuccessful, from clues of the target (first and last letters), and if still unsuccessful, to recognize the presented target word as being associated with the question (the “Of course”, or “That's it!” experience). Pupil size differed according to the nature of the three task demands. Additionally, there were differences based on the type of outcome within the question trial (e.g., between target known but blocked — feeling-of-knowing/tip-of-tongue — and target not known), and the answer trial (recognize vs not recognize the question—answer relationship). The results were related to the search and decisional processes of retrieval.     

Reality therapy: Icing on the cake of behavior modification

The paper presents a conceptual model for therapeutic intervention based on a behavioral orientation. Behavioral therapy is viewed on a continuum ranging from basic operant techniques to cognitive strategies applied to human interaction. It is hypothesized that the elements of reality therapy, with its emphasis on human interaction, are needed to provide closure to the therapeutic intervention and to help maintain new coping behaviors. Utilizing the context of an institutionalized client, suggestions for how this process might occur are discussed.
