Ethical considerations in the use of computers in psychological testing and assessment

Ethical considerations in the use of computers in psychological testing and assessment are discussed. Particular attention is given to existing ethics and standards that provide guidance to users of computerized test interpretation and report-writing programs. Issues covering professional accountability and confidentiality are also discussed as they relate to computer-assisted assessment. Areas of appropriate use of computers in testing and assessment are suggested, including test scoring, the analysis of scores, and generating remedial recommendations. Findings are summarized and several guidelines are suggested for users of computers in testing and assessment.     

Cultural differences in the predictors of depression

This study examined a number of psychosocial factors thought likely to contribute to depression among ethnic Korean and Caucasian students. As hypothesized, Koreans (n = 61) were more depressed than Caucasians (n = 69). Stepwise multiple regression analysis revealed different models for predicting depression in the two groups. Value orientations, a neglected element in the prevailing stress paradigm, contributed substantially to variation in depression, especially among Koreans. Two measures of parental values and three coping strategies accounted for a striking 44% of the variance in Korean youths' depression. Perceived parental traditionalism, the strongest predictor, was associated with higher depression; and perceived parental modernism, with lower depression. For Caucasians, in contrast, only 13% of the variance in depression could be accounted for; and the two significant predictors were academic stress and respondents' own modern values (the latter associated with fewer symptoms). The findings of this study argue for greater attention to the importance of values in studying adaptation to stress.     

Adjustment to hemodialysis treatment through behavioral controls

The present study was conducted to examine the hypothesis that compliant chronically ill patients, typically described as adjusted, reinforce more positive social environments using behavioral controls than noncompliant patients, typically described as maladjusted. Specifically, it is hypothesized that diet-compliant chronic hemodialysis patients emit significnatly more active involvement-in-treatment behaviors and more social behaviors than diet-noncompliant chronic hemodialysis patients. Subjects, who ranged in age from 30 to 77 years, were outpatients at a kidney center. Behavioral observations were conducted to assess the occurrence or frequency of (1) four involvement-in-treatment behaviors that are routinely taught to all patients and (2) two social behaviors, which were patient verbalizations and smiles. The results showed that compliant patients emitted significantly more involvement-in-treatment behaviors and smiles than noncompliant patients. Results support the proposed control framework that compliant, in contrast to non-compliant, chronically ill patients have recourse through positive behavioral controls when adjusting to the stresses of illness. It was proposed that through these controls, compliant patients reinforce positive environments rather than simply respond to life circumstances as given.     

Perceived control and health

Perceived control (PC) is defined as thebelief that one can determine one’s own internal states and behavior, influence one’s environment, and/or bring about desired outcomes. Two important dimensions of PC are delineated: (1) whether the object of control is located in the past or the future and (2) whether the object of control is over outcome, behavior, or process. A variety of constructs and measures of PC (e.g., efficacy, attribution, and locus of control) are discussed in relation to these dimensions and selected studies are reviewed. The issues, controversies, and limits of the research on perceived control and health are addressed in terms of the antecedents and consequences of perceived control. Investigations should clearly conceptualize the object of perceived control, use measures that match the conceptualization, and when attempting to manipulate control, directly measure perceived control. The relation between PC and health outcomes is complex, and different aspects of PC may interact to affect health outcomes.     

Lateral asymmetry of personal optimism

By combining models of cerebral emotional asymmetry and unilateral hemispheric activation, it was hypothesized that orienting to the right would produce greater personal optimism about future events than would orienting toward the left. This was supported significantly in two experiments which differed from each other in their manipulations, hypothetical future events, means of responding, and settings. The results supported previous research on unrealistic optimism and extended the concept to show the effect of induced lateral orientation. It was proposed that this effect is mediated by mood, and possibly by perceived control, and that this methodology can be extended to other behaviors which have proven amenable to mood manipulation.     

The recognition of and empathic response to “personal legends”

The ability to recognize and analyze a personal legend in the conversation of an older person is a useful tool for the skilled, compassionate conversation partner. Having isolated the legend, the empathic listener can offer the teller of the legend the gift of an understanding, clarifying interpretation of its significance.Carolyn K. Dennis, M.

Statistical simulation on microcomputers

The statistical simulation program DATASIM is designed to conduct large-scale sampling experiments on microcomputers. Monte Carlo procedures are used to investigate the Type I and Type II error rates for statistical tests when one or more assumptions are systematically violated-assumptions, for example, regarding normality, homogeneity of variance or covariance, mini-mum expected cell frequencies, and the like. In the present paper, we report several initial tests of the data-generating algorithms employed by DATASIM. The results indicate that the uniform and standard normal deviate generators perform satisfactorily. Furthermore, Kolmogorov-Smirnov tests show that the sampling distributions ofz, t, F, χ², andr generated by DATASIM simulations follow the appropriate theoretical distributions. Finally, estimates of Type I error rates obtained by DATASIM under various patterns of violations of assumptions are in close agreement with the results of previous analytical and empirical studies; These converging lines of evidence suggest that DATASIM may well prove to be a reliable and productive tool for conducting statistical simulation research.     

Using self-evaluation to improve difficult-to-read handwriting of secondary students

We used delayed multiple-baseline and multiple-probe techniques to assess the effects of self-evaluation training on the legibility of cursive handwriting. Five secondary special education students with difficult-to-read handwriting served as participants. All participants improved the legibility of their handwriting during self-evaluation training. A systematic withdrawal of the training package demonstrated maintenance of treatment effects. For the most part, the students' handwriting remained at least 90% legible to judges following the systematic withdrawal of the self-evaluation training.     

Sex differences in visual-spatial ability: The role of performance factors

Two studies were designed to explore the role of performance factors as sources of the frequently noted higher male scores on visual-spatial ability tests. In the first study, the mental rotations test (MRT) was administered to male and female college students of equally high quantitative ability (based on SAT math scores). Although males had significantly more correct responses on the test than did females, their advantage was eliminated when the ratio of correct responses to items attempted was used as the dependent measure. In the second study, the same test was administered to new groups of male and female college students. In this sample, the males had significantly higher SAT math scores. The MRT was administered under standard, timed conditions and under untimed conditions. Both raw and ratio scores were calculated. With SAT math score as the covariate, analyses of covariance indicated that males demonstrated higher performance in the timed, raw-score condition but not in the untimed or in the ratio-score conditions. The theoretical and social policy implications of these studies are discussed.     

Tempo discrimination in infants

An habituation/dishabituation paradigm demonstrates that 2- and 4-month-old infants are able to discriminate auditory sequences that vary slightly in tempo. Discriminations were only observed for intermediate tempi (600 ms but not 100, 300, 1500 ms IOI), suggesting that infants have the same optimal tempo range as adults.
