This commentary on the special section on clinical adolescent psychology (G. Holmbeck & P. Kendall, 2002) reviews and critiques the conceptual and empirical articles that this compilation comprises. As articulated in the conceptual contributions to this collection, two fundamental principles should guide research on the etiology, prevention, and treatment of psychological disorder and dysfunction during adolescence: First, drawing on the field of developmental psychopathology, the study of clinical adolescent psychology should focus on the trajectories of disorder that precede, characterize, and follow adolescence. Second, drawing on the literature on normative adolescent development, the study of clinical adolescent psychology must proceed with an explicit recognition of the unique biological, cognitive, psychosocial, and contextual features that define adolescence as a developmental period. Although the study of clinical adolescent psychology, as evidenced by this collection of articles, is appropriately grounded in the broader enterprise of developmental psychopathology, less progress has been made with respect to die integration of the study of clinical phenomena in adolescence with the study of normative adolescent development.

The coarse acquisition performance of a direct sequence spread-spectrum receiver is analyzed when a linear prediction filter is used for narrowband interference suppression. We show that once an appropriate matching strategy is identified, the linear prediction filter can provide favorable performance when narrowband interference is present over a considerable range of both interference power and bandwidth. In addition, the presence of the filter dramatically improves the performance over the case where there is no filter, except when the interference bandwidth and the power are both small (i.e., when the processing gain provides sufficient interference immunity without the filter). If long spreading sequences are used with moderately sized observation windows, the acquisition performance can be severely degraded when a parallel acquisition scheme is used due to the linear predication filter. We show, however, that a slower serial receiver will provide reliable performance.This work was supported in part by the Office of Naval Research under contract ONR N00014-91-J-1234, the Army Research Office under contract ARO DAAL03-91-0071, and the NSF Center for Ultra-High Speed Circuits and Systems (ICAS).  相似文献

Parenting style as context: An integrative model.   总被引:1,自引:0,他引:1  
Despite broad consensus about the effects of parenting practices on child development, many questions about the construct parenting style remain unanswered. Particularly pressing issues are the variability in the effects of parenting style as a function of the child's cultural background, the processes through which parenting style influences the child's development, and the operationalization of parenting style. Drawing on historical review, the authors present a model that integrates 2 traditions in socialization research, the study of specific parenting practices and the study of global parent characteristics. They propose that parenting style is best conceptualized as a context that moderates the influence of specific parenting practices on the child. It is argued that only by maintaining the distinction between parenting style and parenting practice can researchers address questions concerning socialization processes.

It is widely believed that exposure to sexy content in the mass media leads teenagers to become sexually active. Although most research linking sexy media exposure to adolescents' sexual behavior is cross-sectional, several recent, well-publicized longitudinal studies purport to find a causal connection, which has alarmed the public and prompted criticism of the entertainment industry for its corrupting influence on youth. One problem in research on media effects on sexual activity, however, is that outcomes that are presumed to result from media exposure may actually be due to factors that differentially predispose adolescents to have different degrees of media exposure and are themselves related to sexual activity. We reanalyzed data from one of these longitudinal studies (Brown et al., 2006) using propensity score matching to control for preexisting differences between adolescents with and without high exposure to sexy media. With such controls for differential selection in place, we found no evidence that the initiation of sexual intercourse is hastened by exposure to sexy media.

30 graduate students in clinical psychology (raters) viewed a videotape recording of an interview with a patient after having read 1 of 3 types of posttherapy information about the patient. One group of raters was presented information associated with a good prognosis, one group was presented information associated with a poor prognosis, and the last group received neutral information about the patient. Half of the members of each group were told that the interview was made at the termination of therapy, the other half were told that it was a 1-yr follow-up interview. All raters then completed scales regarding patient's level of adjustment, psychic distress, amount of change, and success of patient's therapy. Only ratings of pre- to posttherapy patient change varied as a function of prognostic information. Results suggest that although poor prognosis patients are perceived as exhibiting more change than good prognosis patients, only final level of functioning determines global judgments of psychotherapy outcome.

Treated 30 individuals (aged 24–82 yrs) with subjective tinnitus aurium with a matching-to-sample feedback procedure. Ss' tinnitus sounds were reproduced audiometrically on all characteristics and were presented to them in the noninvolved ear or in both ears when the tinnitus was binaural. This experimental sound was then reduced in 5-db steps within sessions, and Ss had the task of concentrating on reducing the loudness of their tinnitus until a match was achieved between it and the experimental sound at each new db level. Results show a significant difference in db levels from baseline to final training session. Nearly all Ss demonstrated a marked reduction in tinnitus loudness, with several eliminating it completely.

The present study examined relations among neighborhood structural and social characteristics, parenting practices, peer group affiliations, and delinquency among a group of serious adolescent offenders. The sample of 14-18-year-old boys (N = 488) was composed primarily of economically disadvantaged, ethnic-minority youth living in urban communities. The results indicate that weak neighborhood social organization is indirectly related to delinquency through its associations with parenting behavior and peer deviance and that a focus on just 1 of these microsystems can lead to oversimplified models of risk for juvenile offending. The authors also find that community social ties may confer both pro- and antisocial influences to youth, and they advocate for a broad conceptualization of neighborhood social processes as these relate to developmental risk for youth living in disadvantaged communities.

It is contended that rehabilitation psychologists have remained content to continue using the same techniques for the same types of problems that they used more than a decade ago. Because of a temerity of thought, rehabilitation psychologists have not extended their particular research and technological expertise into the more major areas of health care. Examples are presented in which such psychological techniques as conditioning and biofeedback were employed to treat successfully a variety of serious health problems. Rather than leave the major areas of investigation and treatment to others, as has traditionally been the case, rehabilitation psychologists are urged to utilize their skills in studying and treating the major physical problems of their patients.

Data on adolescents' after-school experiences and their susceptibility to peer pressure were derived from surveys administered to a heterogeneous sample of 865 adolescents in Grades 5–9. Consistent with the findings of previous studies, the results show that Ss who reported home after school were not significantly different from those who were supervised by their parents at home during after-school hours. However, when a 2nd sample of latchkey children (n?=?594) was studied to include greater variation in after-school experiences, Ss who were more removed from adult supervision were found to be more susceptible to peer pressure to engage in antisocial activity. Ss who were home alone were less susceptible to peer pressure than are those who were at a friend's house after school, and those who were at a friend's house, in turn, were less susceptible than were those who describe themselves as "hanging out." Moreover, latchkey Ss whose parents knew their whereabouts and those who had been raised authoritatively were less susceptible to peer influence than were their peers, even if their afternoons were spent in contexts in which adult supervision was lax and susceptibility to peer pressure was generally high.
