Measuring projection tachistoscope shutter characteristics

Projection tachistoscopes have shutters that control the presentation of stimuli. Shutter characteristics such as opening times, closing times, and mechanical reliability are important factors in applications of these tachistoscopes. The device described in this report allows the operating characteristics of shutters used in projection tachistoscopes to be evaluated. The use of the device is illustrated by measurements of three commercially available tachistoscope shutters. Each shutter was characterized by five parameters: opening and closing speeds, the lag between shutter activation and operation, the briefest stimulus presentation that the shutter allowed, and the shutter’s ability to repeat exposure durations accurately.

Coping with breast cancer: The roles of clergy and faith

This paper describes the experiences of 103 breast cancer patients with home pastors and hospital chaplains. Attention was directed at the activities of clergy, the degree to which religious and nonreligious interactions were satisfying to the women, and how these related to their personal faith orientation. Because of the issues of sexual identity and attractiveness entailed by breast cancer, the role of female clergy was also explored. It is evident that religion is an extremely important resource for the majority of these breast cancer patients, and an intrinsic religious orientation helps one cope with breast cancer.     

School stress reported by children in grades 4, 5, and 6.

Stress in the school environment of 269 elementary school children attending Grades 4, 5, and 6 of a metropolitan school district were assessed using the School Stress Questionnaire. The effects of sex, ethnic background (minority vs nonminority), type of classroom placement (regular education versus special education), and family structure (traditional versus nontraditional or divorced) were investigated. Children from nontraditional or divorced families had significantly higher school stress than children from intact families. The possibility that these results are a reflection of society's negative attitudes toward children living in nontraditional families is raised.     

Problems involved in toilet-training profoundly mentally handicapped adults

Toileting difficulties constitute a severe problem in institutions for the mentally handicapped. The present study, in a British institution, is a cross-validation of the approach to toilet training outlined by Azrin et al. in the U.S.A. Although Azrin's approach was basically successful, a number of differences were found in running the programme. These differences, together with practical difficulties encountered, are discussed.     

Word knowledge and production of original verbal responses in deaf children.

Verbal originality scores were obtained from Onomatopoeia and Images, Form 1B, given t0 182 deaf Ss aged 10 to 19 yr. Ss who had been taught the onomatopoetic words scored higher than Ss who had not been taught the words. There was a main effect for age, with older Ss having significantly higher means than younger Ss. No significant interactions occurred.
