The effects of unequal competence and sex on achievement and self-presentation

Female and male college students were divided into high ability and low ability groups on the basis of scores on a problem-solving task. In a second problem-solving session, they worked with a same- or opposite-sex partner whose performance they were accurately informed had been much more or much less competent than their own at the first session. The achievement of highly competent females was higher when their partner was a less competent female than a less competent male. The performance of less competent males and females was lower when their partner was a highly competent female rather than a highly competent male. Results suggested that self-presentation concerns aroused by sex of partner and relative ability can inhibit achievement.This article is based on the first author's master's thesis, submitted to Department of Educational Psychology at Pennsylvania State University.

THE ROLE OF ATTENTION IN THE TREATMENT OF ATTENTION-MAINTAINED SELF-INJURIOUS BEHAVIOR: NONCONTINGENT REINFORCEMENT AND DIFFERENTIAL REINFORCEMENT OF OTHER BEHAVIOR

Because there are potentially serious limitations to differential reinforcement of other behavior (DRO) (which is probably the most widely used treatment procedure for behavior problems), we examined an alternative procedure—noncontingent reinforcement (NCR). Three females with developmental disabilities, all of whom engaged in severe self-injurious behavior, participated. During a pretreatment functional analysis, each subject's self-injury was shown to be differentially sensitive to social attention as a maintaining consequence. Next, each subject was exposed to a DRO treatment and an NCR treatment. During DRO, attention was delivered contingent on the absence of self-injury for prespecified intervals. During NCR, attention was delivered on a fixed-time schedule that was not influenced by the subject's behavior. Results showed that both procedures were highly effective in reducing self-injury, probably because the functional reinforcer for self-injury was used during treatment. Furthermore, there was evidence that NCR attenuated several of the limitations of DRO. These results are particularly interesting in light of the long experimental history of NCR as a control rather than as a therapeutic procedure.     

Differences in Supervisory Needs and Expectations by Trainee Experience,Cognitive Style,and Program Membership

In this study the authors examined relationships between trainees' cognitive style, program membership, amount of practicum experience, and needs and expectations for supervision. Participants were 57 trainees in three graduate programs at a midwestern university. All respondents completed the Myers-Briggs Type Indicator (MBTI; Myers & McCaulley, 1985), the trainee version of the Supervisor Perception Form (SPF-T; Heppner & Roehlke, 1984), and the Supervisory Needs subtest of the Counselor Development Questionnaire (CDQ-SN; Reising & Daniels, 1983). Results suggested that trainees' expectations and needs regarding the supervisory experience differed by amount of practicum experience, cognitive style, and program membership. Differences due to amount of experience were more prevalent than were those due to cognitive style or to program membership.     

Community health nurses' knowledge of, attitudes toward, and involvement with adolescent contraceptive services

A national sample of community health nurses were surveyed to assess their knowledge of, attitudes toward, and involvement with reproductive health services. Results indicated that slightly more than half of the nurses provided or administered contraceptive services to adolescents, although 73% worked in settings where contraceptive services were provided to adolescents. However, only 3.6% indicated that adolescents were their primary client population. The majority (64.3%) stated that they felt as prepared to work with adolescents as they did with adult clients. While 98% were aware that most adolescents are sexually active before seeking family planning services, a minority correctly answered questions about pregnancy and contraception among adolescents. Ninety-five percent agreed that contraceptives should be available to adolescents, and 90% agreed that parental consent should not be required for adolescents seeking contraceptive services. Yet only 21.5% were aware of the implications of the Adolescent Family Life Act.     

Naturalistic memory in learning-disabled and skilled readers

Three experiments compared learning-disabled and skilled readers' performance on naturalistic memory measures, as well as investigated the relationship between memory performance on everyday and laboratory tasks. In Experiment 1, the laboratory task (sentence span task) and everyday memory measures were correlated moderately for both ability groups. Compared to skilled readers, disabled readers performed poorly on the sentence span task, and were less likely than skilled readers to remember information related to common objects and consequential events. Disabled readers were also less likely to rely on external prompts to help them recall everyday information. Experiment 2 extended the previous findings to older subjects and found that the majority of significant correlations between the laboratory (word span task) and everyday memory tasks were isolated to disabled readers. When compared to chronological-age-matched subjects, disabled readers were inferior in recency performance on the laboratory (word span) and natural serial recall (e.g., recall of U.S. presidents) tasks. Experiment 3 showed that under conditions that facilitate item accessibility, ability group differences in recall were comparable. Taken together, the findings indicate that disabled readers' memory deficits are pervasive across naturalistic and laboratory measures at the younger age, but these deficits diminish for older students. Further, the deficits that occur at the older age are due to problems in accessing knowledge.     

Cognitive processes that underlie mathematical precociousness in young children

The working memory (WM) processes that underlie young children's (ages 6-8 years) mathematical precociousness were examined. A battery of tests that assessed components of WM (phonological loop, visual-spatial sketch pad, and central executive), naming speed, random generation, and fluency was administered to mathematically precocious and average-achieving children. The results showed that (a) precocious children performed better on executive processing, inhibition, and naming speed tasks than did average-achieving children, although the two groups were statistically comparable on measures of the phonological loop and visual-spatial sketch pad, and (b) the executive component of WM predicted mathematical accuracy independent of chronological age, reading, inhibition, and naming speed. The results support the notion that the executive system is an important predictor of children's mathematical precociousness and that this system can operate independent of individual differences in the phonological loop, inhibition, and reading in predicting mathematical accuracy.     

The use of a laboratory school protocol to evaluate concepts about efficacy and side effects of new formulations of stimulant medications

Recently, new long-acting formulations of racemic methylphenidate (MPH: Ritalin LA, Metadate CD and Concerta) and amphetamine (AMP: Adderall XR) were developed and are now approved by the Food and Drug Administration (FDA). In addition, dexmethylphenidate (Focalin), the pharmacologically active d-threo enantiomer of MPH, also was approved by the FDA. In the initial phases of development, prototypes of these five new formulations were evaluated using the University of California, Irvine (UCI) Laboratory School Protocol (LSP), in which surrogate measures of efficacy are collected in highly controlled settings rather than clinical measures of effectiveness in the less-controlled, natural environments of home or school. The LSP studies were followed by large effectiveness and safety studies required for gaining FDA approval. These initial efficacy and side effect studies in the LSP provided missing information about the basic pharmacokinetic (PK) and pharmacodynamic (PD) properties of MPH and AMP and produced some new discoveries (i.e., acute tolerance) that were used to help design the final products. The final once-a-day formulations used different drug delivery systems to achieve long-acting efficacy (Ritalin LA, Metadate CD, Concerta, Adderall XR). All four drug delivery systems were based on two processes: first, a bolus delivery (BD) process to achieve rapid onset of efficacy (mg), and second, a controlled delivery (CD) process to achieve rates of delivery (mg/hr) or a delayed bolus (mg) to maintain efficacy. A theoretical approach was used to compare and contrast the new once-a day formulations of MPH by selecting total daily doses (mg/d) that would equate drug delivery by the first process (mg of the initial bolus) and the second process (mg/hr over specified time period). In addition to efficacy, applications of the LSP to measure common side effects related to eating and sleeping were described and discussed.     

Effects of speech accents on interpersonal evaluations: implications for counseling practice and research

This article reviews literature from the fields of psycholinguistics, communications, and social psychology that has examined the effects of speech accents (i.e., regional, national, and international variations in same-language use) on interpersonal attitudes, casual attributions, and subsequent behaviors. The authors link selected findings from this literature to the field of counseling to show that these findings can inform service delivery, particularly counseling conducted with ethnic minority and immigrant populations in the United States. Implications for practice and ideas for future research in this area are also discussed.
