A comparison of self-instructional checking procedures for remediating mathematical deficits

We examined the relative effectiveness of three procedures for teaching long multiplication/division to seven adolescents with learning disabilities: no-checking, end-checking, and multi-checking. During training, each subject was taught by modelling and imitation to verbalize self-instructions in the form of a strategy while solving the problems. The relative effects of the checking and no-checking procedures on accuracy and rate of problems completed were examined in an alternating treatments design. The best treatment was then given alone and a reversal was implemented six weeks later, followed by a return to the best treatment during a final phase. Irrespective of the procedure used, the subjects' accuracy improved while the rate of problems completed decreased. These effects were greatest with the multi-checking procedure for six of the seven subjects. Generalization to untaught problems of various levels of complexity occurred under all procedures. Though maintenance effects were seen during the follow-up, accuracy was generally higher and more reliable when the subject's best checking procedure was reinstated. It is suggested that error detection and correction were important for maintaining high levels of accuracy and that these operated differentially in the three procedures to produce the differing levels of accuracy. The role of other factors such as pre-skill knowledge, complexity of the problem and prior reinforcement history are also considered.     

Traffic congestion, perceived control, and psychophysiological stress among urban bus drivers

The operation of public transit vehicles in urban centers is a highly stressful job. There has been, however, little detailed analysis of what specific characteristics of the psychosocial or physical job environmental of public transit operators contribute to the high levels of job stress associated with this occupation. In the present study, we show a high degree of association between exposure to peak traffic conditions and on-the-job elevations of urinary catecholamines. These significant relations remain after incorporating various controls for possible selection factors (e.g., job seniority) and health-relevant parameters (e.g., age, smoking). Furthermore, we show that reductions in perceived control on the job partially account for the linkages between traffic congestion and psychophysiological stress.

Sport participation among adolescent girls: Role conflict or multiple roles?

This study explored selected roles as criteria for social status among high school females with particular reference to participation in interscholastic athletics. Six hundred and twenty-seven female high school students completed the School Climate Questionnaire and, using a 5-point Likert scale, rated different role/activity choices. There were significant differences between participants and nonparticipants with respect to roles selected for future status; however, no significant relationship was found between groups and their identification of the criteria for peer approval. Overall, high school females exhibited multidimensional self-identities that differed in relation to their involvement in sports and the social groups used as their point of reference.     

The relationship between assertion and sociometric status of children

A correlational study was conducted in an effort to examine the relationship between children's level of assertive skill and their social (sociometric) status. The Ss were 15 male and 15 female elementary school children ranging in age from 9 to 11 yr. Each S was administered: (a) positive and negative peer nominations and roster and rating scale sociometrics; (b) self-report questionnaires concerning their assertive behavior; and (c) standardized interviews to assess knowledge of assertive behavior. In addition, teachers' ratings of children's interpersonal behavior were obtained. Results indicated some degree of correspondence between assertion indices and sociometric ratings. However, correlation coefficients generally were in the low-to-moderate range. Also, several scales from children's self-report and teacher's ratings of children's assertive behavior differentiated high- and low-popular children. Results are discussed in terms of: (1) the utility of employing multiple criteria in assessing social functioning of children; and (2) the need to determine empirically the relevance of assertive and other interpersonal skills in childrens' social repertoires.     

Young adults with intellectual and other developmental disabilities acquire vocational skills with video prompting

Students with intellectual and other developmental disabilities often require substantial support to acquire the skills needed to secure work experience and paid employment. Prior findings suggest that video prompting is likely to be an effective and feasible strategy for establishing such skills. To evaluate this possibility in a special education transition program, we examined the effectiveness of a video prompting procedure in teaching 8 young adults with developmental disabilities to perform job-related tasks (doing laundry, checking in to work, vacuuming, stripping bed). The intervention was effective with all participants. The skills maintained over 3 months, and the participants performed the tasks accurately in a new setting with different materials. Participants were reportedly satisfied with the intervention and deemed it easy to use.     

Dyadic processes of relational turbulence theory

This study tested dyadic processes of relational turbulence theory (RTT) in heterosexual marriages. We tested propositions 1, 2, and 5 of RTT, which propose that uncertainty about the marriage biases cognitive appraisals, and that interference from a partner heightens negative emotions, both of which culminate in relational turbulence for spouses. Guided by these propositions, husbands' and wives' (N = 510; 255 marital dyads) dyadic cognitive and emotional processes were estimated using the actor-partner interdependence mediation model. Consistent with theoretical propositions, we found evidence for actor-actor indirect effects; for both husbands and wives (a) the effect of spouses' relationship uncertainty on their own relational turbulence was mediated by their own biased cognitive appraisals, and (b) the effect of spouses' experienced interference on their own relational turbulence was mediated by their own anger from communicating in the marriage. However, controlling for actor-actor indirect effects, partner-defined processes (i.e., actor-partner and partner-actor indirect effects) uniquely explained husbands' and wives' relational turbulence.     

Early cognitive development and parental education

Relations between cognitive development in infancy and early childhood, and parental education were examined. Previous research has found little association between measures of the parenting environment, including parental education and socio‐economic status (SES), and cognitive development in infants and children under 2 years of age. However, the earlier studies may not have reliably measured individual differences in cognitive abilities, thus, there is uncertainty as to what age elements in the parental environment affect cognitive development. Seventy‐six infants were tested on a range of cognitive tasks at 3‐month intervals between the ages of 9 and 18 months. Information on parental education (a component of SES) was collected. Seventy‐one of the children returned at 27 months and completed the Bayley Scales of Infant Development, Mental Scale, which was used as an outcome measure for the earlier tasks. The findings present a clear indication that cognitive development in early childhood is affected by the parenting environment, at least from as early as 12 months.
