Facilitating accuracy of imitative articulation through reception training

Accuracy of imitation of nonsense words was examined in first- and second-grade children (65–99 months of age) as a function of prior reception training. Two experiments were conducted, involving within-subject comparisons. In the first, one group of words was trained as labels for nonsense objects, a second received noncontingent feedback yoked to the labeling words, a third was presented an equal number of times to control for exposure, and a fourth group was not included in the training phase. Testing involved accuracy of imitation of all four groups of words. Both the feedback and exposure words were imitated less accurately than the labeling words, but more accurately than the nonexposure controls. The second experiment examined the length of the label-object association, using an overtraining procedure. Words which came under the discriminative control of objects for greater numbers of trials were imitated more accurately than those meeting only a minimum discrimination criterion.     

Student physical symptoms and the social climate of college living groups

Student physical symptoms were related to the social climates of university living groups. A Physical Symptom Risk Scale, a new subscale of the University Residence Environment Scale, which relates consistently to physical symptom complaints for male, female, and coed living groups, was developed. Living groups characterized by high student physical symptoms were perceived by students as low in involvement and support, high in competition, and low in student influence. The results indicate that certain types of social environments may be "high risk" settings in that they support and possibly facilitate complaints of physical symptoms. These settings may be amenable to early "environmental diagnosis," preventive counseling, and change-oriented social systems intervention.     

Multitrait-multimethod model of adolescent deviance,drug use,academic, and sexual behaviors

A multitrait-multimethod design was used to test Jessor and Jessor's (1977) problem behavior theory with a sample of adolescents, their parents, and peers. Behaviors included general deviance, drug use, low academic motivation, and precocious sexual behavior. While research has supported this theory, the reliance on self-report data for the majority of this work may threaten the validity of these findings. Results from hierarchical confirmatory factor analyses indicated that the convergent and discriminant validity of the seven behavior constructs was high and method effects were low. A two-factor second-order model, representing General Drug Use and Other Problem Behavior, accounted for a larger proportion of variance in the lower order factors compared to a single-factor model.This research was supported by Grant DA 03706 from the National Institute on Drug Abuse.     

Immigration: going home or going to pieces

Immigration may constitute a family crisis. Because of its lengthy duration, this crisis may be an unrecognized factor in the problem which brings patients into therapy. The immigration crisis may bring an individual into renewed contact with past unresolved emotional issues. It also affects the structure, hierarchies, and values of the family as a system. The therapist who relates only to presenting symptoms and ignores the context of the immigration crisis may lose credibility with patients and miss important therapeutic opportunities. Case studies are given to illustrate the statement.     

Marital discord and psychiatric disorder in children and adolescents

The relationship between marital discord and any DISC-2.1/DSM-III-R child psychiatric diagnosis was explored. Interview data from a community sample of 90 parent/child pairs and a clinic sample of 37 parent/child pairs were analysed. The data were collected at Columbia University/the New York State Psychiatric Institute as part of the pilot project of a multi-site methodological study. Rates of marital discord and DISC diagnoses were found higher in the clinic sample than in the community sample. The association between marital discord and any diagnosis remained significant when other risk and protective factors were controlled. Policy implications and recommendations for future research strategies suggested by the current exploratory study were discussed.     

Repetition blindness in sentence contexts: Not just an attribution?

Selective "blindness" to repeated words in rapid serial visual presentation (RSVP) occurs even when omitting these words compromises sentence syntax and meaning. The contributions of lexical and contextual factors to this repetition blindness (RB) phenomenon were evaluated using three tasks that combined RB and ambiguity resolution paradigms. During an RSVP sentence, a repeated word and matched but incongruous control were presented simultaneously, and participants were asked to report the entire sentence, including only the appropriate word. Substantial RB was evident in impaired report of repeated targets, whereas report of nonrepeated targets was enhanced when the distractor was a repeat. Experiment 2 confirmed these results with reduced reporting requirements, and Experiment 3 demonstrated the independence of repetition and sentence congruity effects. Results across all contexts support a lexical account of RB, which assumes that reactivation and identification of rapidly repeated words are impaired due to the refractory nature of lexical representations.     

The effect of early cognitions on cigarette and alcohol use during adolescence

The present study predicts cigarette and alcohol use in adolescence from the development of children's cognitions in the elementary years. Using latent growth modeling, the authors examined a model using data from 712 participants in the Oregon Youth Substance Use Project, who were in the 2nd through 5th grade at the 1st assessment and followed for 6 annual or semiannual assessments over 7 years. Growth in children's prototypes and subjective norms in the elementary years (Times 1 through 4) were related to their substance use in adolescence (Time 6) through their willingness and intentions (Time 5) to smoke and drink. Across the sample, for both substances, the intercept and slope of prototypes were either indirectly related to use through willingness or directly related to use. Both the intercept and slope of subjective norms were indirectly related to use of both substances through both willingness and intentions and directly related to cigarette use. Results suggest that elementary children have measurable cognitions regarding substance use that develop during the elementary years and predict use later in adolescence. These findings emphasize the need for prevention programs targeted at changing children's social images of substance users and encouraging more accurate perceptions of peers' use.     

Melody recognition at fast and slow tempos: effects of age, experience, and familiarity

Eighty-one listeners defined by three age ranges (18-30, 31-59, and over 60 years) and three levels of musical experience performed an immediate recognition task requiring the detection of alterations in melodies. On each trial, a brief melody was presented, followed 5 sec later by a test stimulus that either was identical to the target or had two pitches changed, for a same-different judgment. Each melody pair was presented at 0.6 note/sec, 3.0 notes/sec, or 6.0 notes/sec. Performance was better with familiar melodies than with unfamiliar melodies. Overall performance declined slightly with age and improved substantially with increasing experience, in agreement with earlier results in an identification task. Tempo affected performance on familiar tunes (moderate was best), but not on unfamiliar tunes. We discuss these results in terms of theories of dynamic attending, cognitive slowing, and working memory in aging.
