MMPI identification of nonrehabilitants among disabled veterans.

Utilized the Minnesota Multiphasic Personality Inventory (MMPI) with IQ scores and selected biographic data to identify drop-outs in a Veterans Administration vocational rehabilitation program. Subjects were 61 male disabled veterans. Data were collected at VA Hospital Richmond, Virginia, between September 1973 and September 1974. Follow-up six months after entrance into training utilized persistence in training or employment as success criteria. Multivariate analysis identified 32 of 33 successful and 25 of 28 unsuccessful subjects with p less than .001. Factor analysis of the best predictors identified MMPI Psychopathic deviate (Pd) Hypomania (Ma), and Lie (L) scales which was interpreted to be a social adjustment factor. Four other factors were identified. Results indicated the MMPI was a useful instrument in the identification of disabled veterans who were likely to experience difficulty in post-hospital vocational rehabilitation.     

Weighing science and politics in local decision making about hazards

As a step towards understanding how local environemntal hazards policy is made, this article explores how Canadian local elected officials gained and assimilated scientific and technical information about the environmental hazards facing their communities. Consistent with previous work in the hazards field, three of Weiss’s (1979) meanings of research utilization were found to be directly applicable. The elected officials expressed the view that reconciling conflicting expert opinion and competing concerns was more difficult and more rightly their responsibility than gathering information. This research demonstrates the utility of focus groups for interviewing elite populations making community scale decisions. Her current research interest in knowledge utilization is the adoption of innovative approaches to environmental policy implementation among regional authorities.     

Educational software evaluation research: Balancing internal,external, and ecological validity

The difficulties inherent in the evaluation of educational software are described in terms of the tradeoffs between internal, external, and ecological validity. Larger issues in evaluation research design and computer-based instruction are highlighted by primary and metaanalytic studies designed to reveal the effects of computer simulations in psychology classrooms and laboratories. The effectiveness of classroom and laboratory computer activities depends on how the inclusion of software, as well as the evaluation process itself, changes the entire instructional process.     

THE EFFECTS OF SEVERE BEHAVIOR PROBLEMS IN CHILDREN ON THE TEACHING BEHAVIOR OF ADULTS

Applied behavior analysts have focused on how adults can influence the problem behavior of children using a variety of behavior modification strategies. A related question, virtually unexplored, is how the behavior problems of children influence adults. This child-effects concept was explored empirically in a study involving 12 adults who were asked to teach four pairs of children in which one member of the pair exhibited problem behavior and the other typically did not. Results demonstrated that problem children displayed tantrums, aggression, and self-injury contingent on adult instructional attempts but not at other times, whereas nonproblem children showed little or no problem behavior at any time. Importantly, from a child-effects perspective, adults engaged in teaching activities with nonproblem children more often than with problem children. Also, when an adult worked with a problem child, the breadth of instruction was more limited and typically involved those tasks associated with lower rates of behavior problems. The implications of these results are discussed with respect to theories of escape behavior, current assessment practices, and intervention issues related to maintenance. The existence of child effects suggests that problem behavior may be better understood when it is conceptualized as involving a process of reciprocal influence between adult and child.     

The primary personality factors of Hawaiian, middle adolescents

To determine whether the primary personality factors of Hawaiian, middle adolescents were the same as those Cattell postulated in 1970, for adolescents on the mainland of the United States, and in 1974 for adolescents in Germany, a personality questionnaire representing those factors completed by 694 Hawaiian, middle adolescents (M age = 15.9 yr.) was factor analyzed. Despite the analysis adhering closely to the recommendations of Cattell stated in 1973 and 1978, the eight factors derived are not the set of primary factors postulated for the other populations. Six of them do appear to be, however, primary factors within a set of seven reported in 1988 for a younger population of Hawaiian, early adolescents. In addition, these six factors also appear to be similar to the major constructs in the psychoanalytic theories of Freud and Horney.     

Imagery skill and preference in bilinguals

A number of studies have reported differences in the performance of bilinguals and monolinguals in verbal tasks. It has been suggested that one source of this difference is a greater tendency among bilinguals to use non-verbal ways of representing events, because of the potential for confusions between their two verbal codes. In the present study, bilingual and monolingual college students were compared on three dimensions of self-reported aspects of imagery—control, vividness and preference—as well as on a performance measure of spatial manipulation skill. When these tasks were preceded by a nominally verbal activity (prose comprehension), there were no group differences on the self-report or objective imagery measures. In contrast, when they were preceded by an imagery rating task, some evidence of a compensatory reliance on spatial codes among bilinguals was obtained. Implications of these task induction effects on both subjective and performance measures of a skill were discussed.     

Comparing the effects of static and dynamic signals during multiple schedules

The extent to which multiple schedules are an effective schedule thinning method following functional communication training (FCT) relies on the control the schedule-correlated stimuli exert over behavior. Thus, the stimuli used to signal the schedule in place (e.g., reinforcement and extinction) in a multiple schedule arrangement require special attention. To date, the majority of the research on multiple schedules has evaluated the use of different arbitrary signals as schedule-correlated stimuli (e.g., poster boards). These signals are considered static as they lack movement. More recently, some studies have successfully used dynamic signals, which include movement or animation, within multiple schedule arrangements. However, the extent to which one type of signal may result in faster stimulus control over behavior has not been evaluated. Thus, the purpose of this study was to compare the use of static and dynamic signals as schedule-correlated stimuli in multiple schedules used within the context of FCT. Four children diagnosed with autism spectrum disorder participated in the study. The results suggest that no differences in discriminated manding were observed for three out of four participants. Only dynamic signals resulted in discriminated manding for one participant.

Hypertension differentially impacts cognition in men and women in early midlife

The current study aimed to understand how sex differences in the timing of hypertension onset contribute to early midlife risk for cognitive decline that may differ by sex and whether sex-dependent advantages in normotensive populations are influenced by the presence of hypertension. One hundred and ninety-five adults aged 45–55 from the New England Family Study underwent neuropsychological testing to assess attention, executive function, and memory. Physician-diagnosed hypertension status was self-reported via questionnaire. Mid-adulthood hypertension was associated with worse performance on measures of attention and memory, but the cognitive domains impacted varied by sex. Hypertension was associated with only attention in men, whereas in women it was associated with attention and associative and working memory. Sex differences in midlife cognitive performance found in normotensive adults were attenuated in those with hypertension. Our results underscore the importance of accounting for sex when assessing the impact of hypertension on midlife cognition that could be indicative of later decline and risk for cognitive impairment and dementia, given hypertension is an independent risk factor.     

Why do U.S. conservatives take fewer COVID-19 precautions? The role of worry,perceived risk,and governmental trust

Research suggests a U.S. political ideology gap for taking COVID-19 precautions, but we do not know the role of cognitive risk (assessed here as perceived risk) and affective risk (assessed here as worry) in explaining why conservative Americans participated in fewer recommended precautions (e.g., mask wearing) and whether governmental trust attenuates the effect. We predicted that conservatives (compared with liberals) would take fewer precautions because they thought they were less at risk and were less worried about COVID-19, but that this would be more pronounced for those with low governmental trust. In this study, U.S. adults (representative sample: N = 738; M_age = 46.8; 52% women; 78% white) who had not had COVID-19 took two online surveys 2 weeks apart during the first wave of the pandemic (April 2020). Participants reported ideology, perceived risk of getting or dying of COVID-19, worry about COVID-19, and trust in the CDC and state officials at baseline. At follow-up, participants reported on COVID-19 precautions: (1) prevention behavior participation (e.g., mask wearing) and (2) behavioral willingness for future behaviors (e.g., vaccination). Results showed that, politically conservative Americans took fewer precautions due to lower worry (but unexpectedly not due to lower perceived risk). As predicted, when trust was high, the ideology gap was muted for predicting precautions as well as for predicting perceived risk and worry. In sum, conservatives worried less about COVID-19 which predicted fewer precautions, but trust in governmental institutions reduced this ideological gap. Improving governmental trust could be one fruitful path to increasing COVID-19 precautions.
