SVIB profiles of 1169 freshmen entering a college of engineering were grouped according to total occupational scale profile similarity into 28 code types. Mean scores or percentages for the individuals in each code type were compared to base rate values for income variables including ability, personality, and socioeconomic data and outcome variables including academic progress, choice of major, counsel-seeking behavior, and place of residence. The data for four code types were presented together with examples of how the results might be used by a counselor. The investigators concluded that SVIB profile types can be useful in acting as moderator variables to predict student characteristics, and that total profile analysis of the SVIB occupational scale merits further attention.  相似文献

Evidence suggests that for close retinal areas a correlation in sensitivity exists between the areas. Correlations as a function of distance from fixation and between areas were studied. In Experiment I, both forms were equidistant from fixation and five different distances apart. In Experiment II, both forms fell on an imaginary line through fixation. The forms usually did not fall on equally sensitive areas as in Experiment I. Both experiments showed that accuracy was lower for two- than for one-form displays. Closer forms had the lowest accuracy, suggesting perhaps mutual contour masking. However, in the sense of an intratrial correlation, no significant relationships were found. These two types of independence were discussed in terms of contour masking and varying sensitivity.  相似文献

The National Adolescent and Child Treatment Study (NACTS) was designed to study children identified and served by the public mental health and special education systems as seriously emotionally disturbed. Children (N=812) and their parents (N=740) participated in the first wave of data collection in this longitudinal study. Subjects lived in six states, with approximately half in psychiatric residential treatment centers and the other half in public school special education programs. A multi-method, multi-source methodology was employed. The sample is characterized by externalizing problems, poor adaptive functioning, and substantial academic deficits. Residential children were more likely to have blended families, were more likely to have previously received residential treatment, and had higher rates of conduct disorder, anxiety, and attention deficit disorder, as measured by the Diagnostic Interview Schedule for Children. The two groups did not differ on intelligence, age of onset, or rates of schizophrenia or depression. The data suggest the presence of greater at-risk factors in the residential group and different paths of entry into special education and residential treatment programs.  相似文献

The prolonged-inspection technique has been used to demonstrate effects of satiation on the perception of ambiguous figures. We propose that the inspection phase, in which subjects view an unambiguous version of the stimulus prior to observing the ambiguous figure, does not create neural fatigue but rather provides a context in which the alternative percept is apprehended and gains perceptual strength through processes such as imagination or memory. The consequent availability of the alternative organization drives the perceptual phenomena that have been thought to reflect satiation. In Experiment 1, we demonstrated that (1) preexperimental exposure to the target figures and (2) allocation of attention to the-inspection figures-were both necessary in order to obtain results similar to those predicted by the satiation model. In Experiment 2, we obtained similar results, finding that effects of prior inspection were greater the greater the amount and availability of information regarding the alternative percept during the inspection phase. Subjects who generated visual images of the noninspected alternative during inspection yielded results comparable to those from subjects to whom both versions were presented isuaily.  相似文献

Describes the multilevel outcomes of a collaborative preventive intervention for ninth-graders at risk for school failure using qualitative and quasi-experimental methods. Teachers, administrators, and researchers implemented innovative practices communicating positive expectations for low-achieving adolescents in their transition to high school. Changes were made in the practices of curriculum, grouping, evaluation, motivation, student responsibility, and relationships (in the classroom, with parents, and in the school). Both implementation and evaluation evolved as a function of collaboration. Change was promising but not uniform. Project teachers became more positive about students and colleagues, expanded their roles, and changed school tracking policies. The 158 project students, in contrast to the 154 comparison students showed improved grades and disciplinary referrals post-intervention and increased retention in school 1 year later, but their absences rose and improved performance was not maintained. The implications of this analysis for school-based interventions and its evaluation are discussed.  相似文献

Improvements in visual acuity following vision training were evaluated for an 1112-yr-old myopic male. Initial increases in the distance at which the S could discriminate letters were found. However, performance began to deteriorate as training progressed. A negative-reinforcement procedure was employed in order to rule out motivational factors potentially related to this decreased performance. Using a changing criterion within an ABCBC reversal design, the distance at which the S correctly discriminated letters increased by more than 412 times and was clearly related to the reinforcement procedure.  相似文献

Sickle cell disease (SCD) occurs in 1 of every 400 to 500 African American births. Despite its prevalence, there has been a relative dearth of attention paid to SCD in the psychological literature. African American SCD adolescents and young adults, individuals at an already vulnerable developmental stage, are at increased risk for psychological distress and psychosocial impairments (e.g., depression and low self-esteem, poor social and academic/vocational functioning). Such difficulties often result in problematic adherence to medical regimens, and thus represent a potentially serious clinical and public health problem that merits the attention of psychologists working in medical settings. This article (1) reviews the psychosocial needs peculiar to SCD patients transitioning from adolescence to young adulthood; (2) applies a culturally informed stress-coping-adjustment framework to assess and address the psychological status, psychosocial functioning, and disease outcomes of these individuals; and (3) describes a culturally and developmentally sensitive, psychoeducational group intervention.  相似文献
