The Adolescent with Diabetes and the Public Schools—A Misunderstanding

The academic aptitudes and school achievement of the children with diabetes in 58 junior and senior high schools have been explored. Teachers and school counselors were queried concerning their understanding of diabetes, and its management and nature of interaction with the child and his parents. Implications for public school education of the chronically handicapped child were presented.     

Elephants in the living room

The elephant experience involves too much stimulation or input for a person to integrate. School personnel may help each other and their students to cope more effectively with these experiences by understanding the symptoms, the common sources, and the process of using them constructively. The symptoms are preoccupation, avoidance, overreaction, and flight into activity. Common sources are grades, test scores, and athletic success. The process of using them constructively involves facilitative people, use of personal resources, review of progress toward assimilation, and personal integration of experiential meaning. The elephant experience is seen as a source of learning that may be either devastating or enriching, and the challenge to the facilitator is to help each individual make it constructive.     

Orientation of letters and errors in their recognition

Subjects named alphabetic characters that had been rotated, reflected, or inverted. Inversions induce more errors than mirror reflections and reflections induce more than rotations. In a significant number of mistakes a transformed character was assumed to be normally oriented, but in most a transformed character was confused with the mirror image of the original. The data suggest the existence of an “orientation set” in which the identiflcation of ambiguous characters depends largely on their anticipated orientation. The individuality of the data for the different orientations suggests that different transformations are compensated for in part by different mechanisms.     

The recording of continuous variation along four dimensions

A system is described for signalling, recording and analysing continuous changes in up to four dimensions applicable to the visual after-image and other phenomena. Some advantages of the method are discussed.     

A new principle of pellet feeder design

Most current commercial devices dispense dry food pellets by moving the pellets horizontally toward a discharge point. Individual pellets, captured by perforations in a horizontal metal disk, are discharged one by one by stepwise rotation of the disk within the pellet reservoir. In our laboratory, where the average pellet discharge rate is some 20,000 pellets per week, feeders of this type produced occasional problems. Some were electronic; others involved failure always to capture a pellet in each perforation, particularly when the pellet supply was low. But the most common problem was an accumulation of pellet chips and dust under and around the perforated disk, which ultimately jammed the mechanism. Despite weekly cleaning and maintenance, troubles arose at least twice a month, prompting a search for a simpler pellet-feeder design which would be more reliable and require less maintenance. The present pellet feeder employs a vertical rather than horizontal design principle. It has been used extensively in operant conditioning applications for more than a year. More than 200,000 pellets have been reliably discharged from a single feeder without a breakdown. No maintenance, other than a weekly cleaning of the discharge tube, has been required.
