OPERANT PROCEDURES AND THE COMATOSE PATIENT

Operant procedures were tested on three patients who had been in vegetative coma for 6 months, 10 months, and 38 months. A discrete trial procedure was used to test compliance to verbal requests for three behaviors for each patient, including lateral head movement or finger movement, eye focus or eye squeeze, and mouth movement. The design for each patient consisted of multiple baselines across three behaviors with a withdrawal phase and a reinstatement phase (ABAB) for one behavior. Baseline phases were followed by contingent music phases in which 15-second taped excerpts of patients' preferred music sounded immediately following the emission of targeted behaviors. The contingent music treatment affected all three behaviors for Patient 1, but was less effective for two out of three behaviors for the second and third patients who had been in coma for more extensive periods of time. Results are discussed in terms of the potential contributions of the use of operant assessment and treatment procedures in an area of medicine where they have not been used before.     

Measuring ‘Rejection of christianity’ among 14–16-year-old adolescents in Catholic and Protestant schools in Northern Ireland

In response to suggested limitations associated with the positive valency of conventional scales employed to measure attitudes towards Christianity in previous research among adolescents in Northern Ireland, this paper describes the development of a new scale with negative valency. Item selection, the internal structure of the scale, reliability and construct validity are established on a sample of 875 fourth and fifth year pupils attending ten Catholic and ten Protestant secondary schools in Northern Ireland. Tentative scale norms are presented separately for male and female pupils attending Protestant and Catholic schools in Northern Ireland. Suggestions are offered for the application of the scale in future research.     

Personality,time of day and delayed memory for tv news

An experiment was conducted to test the effects of time of day on delayed memory for televised news stories. Three groups received the same sequence of 6 news stories at 09.30, 13.30 and 16.30, respectively. Unexpected tests of free recall, cued recall and recognition were given about 2 hr after news presentation. Results showed that memory performance improved slightly across the day on tests of recall, and significantly so on recognition. Personality differences were also examined. In general, introverts remembered more than extraverts and differences between them were most marked during the late-afternoon session especially on free recall and when minimal cuing was provided. The results support previous time-of-day findings for delayed retention of complex learning materials. Personality differences observed here are consistent with predicted introvert-extravert differences in memory performance predicted by Eysenck's modified action-decrement hypothesis.     

A microcomputer system for temperature biotelemetry

A microcomputer (Apple II) system for recording body temperature measured by a commercially made, implantable biotelemetry device (Mini-Mitter) is described. The system includes an inexpensive radio receiver interface circuit and software written in BASIC and 6502 assembly language. The utility of the system is illustrated in a study that shows that various handling procedures (including that normally involved in rectal temperature measurement) elevate body temperature in rats.     

The Relationship Between Performance on the Gordon Diagnostic System and Other Measures of Attention

Tests purporting to measure attention were administered to college students to examine their relationship to three relatively new tests of attention from the Gordon Diagnostic System (GDS). All subjects received the Standard Delay, Vigilance, and Distractibility Tests of the GDS. In addition, 69 of 136 subjects received the Digit Span, Arithmetic, and Digit Symbol subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R), and Kagan's Matching Familiar Figures Test. After the GDS, the other 67 subjects received the Visual Span subtest of the Wechsler Memory Scale-Revised (WMS-R), and the Stroop. Replication (across two studies) and gender influences were not evident on GDS performance. Performance data on this test for these 136 college students, collapsed across replication and gender, are presented. Although within-test correlations were strong, correlations between tests were weak. A ceiling effect on the Vigilance task may have effected its correlations with other tests. Results suggest that the GDS tasks are not substitutes for commonly used tests of attention, but may be useful as an additional source of information in the assessment of attention.     

The Impact of Acculturation and Cultural Values on Hispanic Immigrants’ Parenting

This study explored the process Hispanic immigrant families undergo when immigrating to the United States through the implementation of a constructivist grounded theory methodology. The theory illustrates the process in three phases: Arriving to a new country, Integrating new values, and Maintaining values. Through these phases the constant interaction between cultures and its influence in family dynamics is illustrated. More specifically, this theory suggests immigrant families are open to include elements of the new culture encountered while keeping elements of their native culture present once their basic necessities are met. The sample of the study consisted of 16 parents. These parents incorporated the English language, granted greater freedom to their children, became more involved with the school system, included American traditions in their celebrations, and altered their discipline methods based on their interaction with the new culture. Additionally, parents maintained the value of respect, the Spanish language, fostered family cohesion, and instilled their spiritual beliefs to their children.     

Persistent versus Periodic Experiences of Social Victimization: Predictors of Adjustment

This study examined self-reports of social victimization and parent reports of adjustment for a sample followed from fourth through seventh grades. Different patterns of social victimization experiences were identified; of the 153 students (79 girls) with complete data, 24% reported chronic social victimization, 23% reported transient experiences of social victimization, and 53% reported being socially victimized at no more than one time point. We examined whether students who experienced persistent and periodic social victimization were at greater risk for internalizing problems than nonvictims. Persistently victimized children demonstrated continuously elevated levels of internalizing problems. Children who were not originally victimized by social aggression but became victimized with time did not demonstrate higher levels of internalizing problems than did nonvictims. Findings were mixed for those who escaped social victimization during this period. This research was supported by NIMH grants R01 MH63076 and K02 MH073616. We are deeply grateful for the participation of children and families in this study and for the cooperation of a local school system that wishes to go unnamed. We thank Mikal Galperin for her help with recruiting and retaining the sample.     

The Animal = Male Hypothesis: Children's and Adults' Beliefs About the Sex of Non–Sex-Specific Stuffed Animals

The Animal = Male Hypothesis, a variation of Silveira's People = Male Hypothesis (Silveira, 1980), was examined. In Study 1, children ages 3–10 years and adults told stories about a gender-neutral stuffed animal, in Study 2 children ages 5–6 years told stories about 3 neutral and 3 feminine animals, and in Study 3 children ages 5–7 years told stories about 2 neutral animals, observed an adult model use feminine pronouns to refer to an animal, then told stories about 2 more animals. Dependent variables were the pronouns participants used to refer to the animals and what sex they believed the animals were. Results showed strong evidence for an animal = male bias in all 3 studies among children and adults of both sexes on both dependent measures. There were few sex-related differences. The modeling intervention was not successful in reducing the bias.
