Adolescent health needs. II: Utilization of health care by adolescents

In a random, mailed survey, 730 adolescents supplied information on their patterns and preferences for health care. The majority of respondents reported that they usually receive medical care from a private physician. Girls consulted physicians more frequently than boys, but there was no significant variation by age or social group. As the age of the respondent increased, the proportion visiting pediatricians decreased. When asked what they liked and disliked about their physician, respondents placed great emphasis upon the personal characteristics of the practitioner. Long waiting periods were the most common complaint. A significant proportion of adolescents with health concerns do not consult a health professional, even in cases where efficacious treatment may be available. Nervous/emotional problems, obesity, and birth control are concerns of adolescents which should be discussed with health professionals.     

The unraveling of a treatment paradigm: a followup study of the Milan approach to family therapy

A 2-year followup study was conducted to determine the efficacy and degree of satisfaction with Milan-style family therapy with families refractory to other treatment interventions. Fourteen families and 5 couples who received Milan-style family therapy participated in the study. Family outcome was found to be improved in 56% of parents and 89% of identified child-patients at followup. Improved self-outcome at followup was reported by 56% of fathers, 67% of mothers, and 78% of identified child-patients. A substantial percentage of fathers (68%) and mothers (59%) reported that at least one family member sought further therapy posttreatment. Factors associated with either parent's positive perception of the treatment in general included the time interval between sessions, experiencing the treatment as brief rather than long, and positive feelings for the group behind the mirror. Mothers who reported liking the treatment reported better family outcome. For mothers, disliking the treatment was related to family members seeking further treatment. The more negative the mothers' and fathers' spontaneous comments about therapy were, the more likely that a family member would seek further alternative psychotherapy. The outcome results are explained in terms of the treatment families' negative reactions to some aspects of the therapist's stance and to the group behind the one-way mirror, as in Milan-style therapy. The importance of modifying Milan-type therapy to foster a positive attitude toward the treatment procedures and the therapist's interventions is discussed.     

Language development after unilateral brain injury.

This longitudinal study describes the growth of syntactic abilities and vocabulary size in nine children with unilateral antepartum or perinatal brain injury. Five children with left hemisphere damage (LHD) and four with right hemisphere damage (RHD), ages 15 to 48 months, were evaluated on three or more occasions. Language samples generated from parent-child interaction were transcribed, coded, and analyzed using the Child Language Data Exchange System. Individual growth trajectories were constructed by graphing three dependent variables--MLU, scores on the Index of Productive Syntax (IPSYN), and number of different words--as a function of the child's age. One subject remained in a prelinguistic stage throughout the study. Simple linear functions best described the growth of MLU, IPSYN scores, and vocabulary in the other eight children. The slopes of the individual growth trajectories, the graphic representations of rates of progress, were comparable in the eight children. Seven children showed developmental delays in initial word use and five in the onset of multiword utterances. However, by age 24 months, four children with LHD and two children with RHD had syntactic capabilities comparable to those of children without brain injuries. The developmental patterns suggested that both cerebral hemispheres may play critical roles in the very earliest stages of language acquisition. Some unilateral lesions caused little discernible effect on language outcome in the toddler-preschool years after the initial developmental delays.     

Speech production, syntax comprehension, and cognitive deficits in Parkinson's disease.

Speech samples were obtained that were analyzed for voice onset time (VOT) for 40 nondemented English speaking subjects, 20 with mild and 20 with moderate Parkinson's disease. Syntax comprehension and cognitive tests were administered to these subjects in the same test sessions. VOT disruptions for stop consonants in syllable initial position, similar to those noted for Broca's aphasia, occurred for nine subjects. Longer response times and errors in the comprehension of syntax as measured by the Rhode Island Test of Sentence Comprehension (RITLS) also occurred for these subjects. Anovas indicate that the VOT overlap subjects had significantly higher syntax error rates and longer response times on the RITLS than the VOT nonoverlap subjects--F(1, 70) = 12.38, p less than 0.0008; F(1, 70) = 7.70, p less than 0.007, respectively. The correlation between the number of VOT timing errors and the number of syntax errors was significant. (r = 0.6473, p less than 0.01). VOT overlap subjects also had significantly higher error rates in cognitive tasks involving abstraction and the ability to maintain a mental set. Prefrontal cortex, acting through subcortical basal ganglia pathways, is a component of the neural substrate that regulates human speech production, syntactic ability, and certain aspects of cognition. The deterioration of these subcortical pathways may explain similar phenomena in Broca's aphasia. Results are discussed in relation to "modular" theories.     

Activity patterns and time budgeting of Aplysia fasciata under field and laboratory conditions

Activity patterns of Aplysia fasciata were observed in a protected port environment and in an aquarium. In both, major activities were feeding and mating, which collectively took up about 45% of the total time of the animals. Active behaviors occurred primarily at night; much of the day was spent in the inactive state. Activities were highly synchronized, with large numbers of animals performing the same behaviors simultaneously at a specific time. Mating and eating occurred primarily at different times; relatively few animals were observed performing these behaviors simultaneously. Many animals laying eggs were simultaneously mating as females.     

Relation between pronunciation and recognition of printed words in deep and shallow orthographies

The processes responsible for recognition and pronunciation of printed words were studied by means of lexical decision and naming experiments. Two languages were examined: English, which has a complex and deep correspondence between spelling and speech, and Serbo-Croatian, in which the correspondence is simple and direct. It was hypothesized that reliance on articulatory coding (instead of on mediation by the internal lexicon) would be greater for Serbo-Croatian because its shallow orthography would allow more efficient use of spelling-to-speech correspondences. Each target stimulus was preceded by a word that was either related or unrelated semantically. Semantic priming of target words facilitated performance in both lexical decision and naming for English, results suggesting an influence of the internal lexicon on both processes. In contrast, semantic priming facilitated only lexical decision for Serbo-Croatian, which suggests that naming, at least in that language, is not strongly influenced by the internal lexicon. Further, in Serbo-Croatian, lexical decision and naming latencies were correlated when both tasks were not semantically primed and were uncorrelated when either or both tasks received semantic priming. This suggested that articulatory coding is used in lexical decision, at least under conditions in which contextual semantic facilitation is absent. In contrast, in English, lexical decision and naming were correlated uniformly whether semantic facilitation was present or not, which, when considered with the effect of semantic facilitation on naming, suggested a stronger influence of the internal lexicon on both recognition and pronunciation.     

The comparison of antisocial and prosocial children on multicriterion measures at summer camp

Eighty-four prosocial children and 14 children defined as antisocial according to various diagnostic measures utilized by the professional therapeutic community were compared as to incidences of prosocial, nonsocial, and antisocial behaviors exhibited at a summer camp. Additionally, the children and their group counselors completed various inventories posited to measure antisocial behavior. A time-sampling procedure used to secure behavioral measurements on the children each day, when possible, during 60-minute intervals for a 5-week period, revealed no significant differences on prosocial,nonsocial, and antisocial behavior. Self inventories provided data contradictory to the behavioral data. The results of the study are discussed in terms of the difficulties involved in operationalizing the concept of antisocial behavior and the possibility that the antisocial children may have been labeled.
