Influence of Racial/Ethnic Membership and “Therapist Culture” on Therapists' Worldview

The authors investigated 2 competing hypotheses related to therapists' worldview and therapists' race/ethnicity: (a) whether therapists of different racial/ethnic groups differed on worldview reflecting group membership, and (b) whether therapists were similar to each other on worldview reflecting membership in a “therapist culture.” Results indicated that therapists shared similar worldviews regardless of group membership, and differences found between therapists based on racial/ethnic membership were minimal.     

The Effects of Direct Questions on Preschool Children's Responses to Indirect Requests

Indirect instructional approaches, such as responsive interaction, are common in inclusive early childhood settings. Unfortunately, young children with disabilities do not always have the skills to take advantage of these learning opportunities. Teaching children with disabilities to be more responsive to developmentally appropriate indirect instructional strategies may help them take advantage of and benefit from available learning opportunities in inclusive settings. The purpose of this research was to examine the extent to which presenting a series of direct questions increased children's attempts to respond and correct responses to indirect requests. Increased attempts to respond and correct responses to indirect requests were evident for all participants with whom the intervention was implemented. Three of the participants continued to attempt to respond and responded correctly to indirect requests when intervention procedures were removed. The contributions of these findings to literature on language instruction with young children, implications of the findings for practitioners, methodological limitations, and suggestions for future research are discussed.     

How monkeys see the eyes: cotton-top tamarins’ reaction to changes in visual attention and action

Among social species, the capacity to detect where another individual is looking is adaptive because gaze direction often predicts what an individual is attending to, and thus what its future actions are likely to be. We used an expectancy violation procedure to determine whether cotton-top tamarins (Saguinus oedipus oedipus) use the direction of another individual’s gaze to predict future actions. Subjects were familiarized with a sequence in which a human actor turned her attention toward one of two objects sitting on a table and then reached for that object. Following familiarization, subjects saw two test events. In one test event, the actor gazed at the new object and then reached for that object. From a human perspective, this event is considered consistent with the causal relationship between visual attention and subsequent action, that is, grabbing the object attended to. In the second test event, the actor gazed at the old object, but reached for the new object. This event is considered a violation of expectation. When the actor oriented with both her head-and-eyes, subjects looked significantly longer at the second test event in which the actor reached for the object to which she had not previously oriented. However, there was no difference in looking time between test events when the actor used only her eyes to orient. These findings suggest that tamarins are able to use some combination of head orientation and gaze direction, but not gaze direction alone, to predict the actions of a human agent.

A matter of time: novel nouns mark object categories when delays are imposed

In previous work, preschool-aged children have revealed a specific expectation that novel count nouns (but not adjectives) will refer to object categories (but not to object properties or to thematic relations). However, in these tasks, children have been permitted to extend a novel word immediately after it has been introduced. The current experiments test the hypothesis that the noun-category bias is sufficiently robust to hold up even when a delay is imposed between a naming episode and the child’s opportunity for extension. To capture this phenomenon experimentally, we imposed delays of 30 s (Experiment 1) and 1 h (Experiment 2). Across both delay conditions, children in a ‘novel noun’ condition revealed a strong inclination to consistently choose other members of the same object category as the (previously named) target. Children in either a ‘novel adjective’ or ‘no word’ condition revealed no taxonomic inclination. These results establish the power of the noun-category bias in situations that more closely approximate some of the very real challenges that children face in mapping and extending novel words.     

Evaluation of an islandwide screening,assessment and treatment program

This article reports on the effectiveness of the Islandwide Screening, Assessment, and Treatment Program of the Child Development Project in Bermuda. From 1982 to 1984, approximately 1100 families with 2-year-old children were screened for children's cognitive and language delay, for behaviour management problems and for other home characteristics that put children at risk for later school failure. Children who failed the screening and subsequent assessment procedures (of whom random samples received treatment) and samples of others who passed screening and assessment were evaluated from 1984 to 1986 at 4 years of age. This article focuses on the results of the cognitive and language programs; the more problematic behaviour management analyses were reported elsewhere (Miller and Scarr, 1988). The screening procedures and assessment measures developed for this project were themselves evaluated and adjusted to maximize efficiency and costeffectiveness. The screening and assessment procedures proved effective in bringing to the attention of the Child Development Project those families and children who need developmental services, and in not overidentifying normal children as potentially delayed in development. Two kinds of treatment services were compared: The Mother-Child Home Program (MCHP), administered by paraprofessional toy demonstrators, and other interventions tailored by professionals to the language and cognitive problems of the child (called ‘tailored programs’). Children who were not extremely delayed or disturbed were randomly assigned either to the MCHP or to a tailored program. Neither intervention program was preferable to the other. Even though improved, the 4-year-olds identified as developmentally delayed at 24 months still lagged behind children who passed all parts of screening and those who failed screening but passed assessment 2 years earlier. The screening and assessment procedures were very effective in the early identification of children with developmental problems, but the treatment programs failed to bring most children to normal levels of cognitive and language functioning.     

Psychological impact of breast cancer on the patient and the family: A clinical perspective

Breast cancer is the most frequently occurring cancer in women, with 182,000 new cases diagnosed in 1993. Breast cancer will strike a sizable percentage of women during the child-rearing years impacting, therefore, not only on the woman, but on the significant others in her life. This article explores the impact of breast cancer for the patient's life partner, parents, and children. A model intervention program for cancer patients with young children, piloted at the Derner Institute and developed in conjunction with the American Cancer Society, is also discussed.     

Lack of early child care effects on school-age children's social competence and academic achievement

Teacher ratings of social competence and academic achievement were obtained from a sample of 127 Bermudian children at ages 5, 6, 7 and 8 years. The children were studied first during their pre-school years, when they had been exposed to various amounts and qualities of day care. Quality of care was found to be important to the children's intellectual and social development while they were in the day care settings but not after 1–4 years of primary schooling. In hierarchical and simultaneous regressions, family background characteristics, not child care amounts or qualities, were found to be predictive of social competence and academic achievement in the primary grades. By school age, the effects of infant and preschool child care experiences were no longer influential in children's development, but family background continued to be important. These findings and their implications for child care are discussed.     

Key membership and implied harmony in Western tonal music: Developmental perspectives

In three experiments on the psychophysical measurement of pain, electrocutaneous currents were applied to the volar surface of the forearm. In the first experiment, a conventional category scaling method was compared with the rating method of signal detection. The results of both methods were analyzed in detection-theory terms to derive receiver operating characteric curves and measures of the discriminability of adjacent currents. The rating method yielded larger discriminability values than the category scale did, and that method was therefore used in the subsequent experiments to examine the effect of a topical anesthetic on discriminability. When the stimuli were applied through surface electrodes, no effect of the topical anesthetic on discriminability was found, but when the stimuli were applied to a more localized area by intradermal needle electrodes, a dose-dependent effect of the anesthetic on discriminability occurred. For this experiment, the slope of the cumulative sensitivity function increased with increasing elapsed time since the removal of the anesthetic. This result is congruent with the theory that discriminability can serve as a measure of sensitivity to painful stimuli.
