Attributional styles of aggressive boys and their mothers

To determine if mothers of aggressive boys have the same propensity as their sons to infer hostile intentions in ambiguous interpersonal situations, 50 mothers of aggressive and nonaggressive boys were each asked to interpret hypothetical situations involving themselves with their child, their partner, and a peer as well as hypothetical situations involving their child in interaction with classmates and teachers. Their sons also were each requested to interpret hypothetical situations involving themselves with their mother, a teacher, and a classmate. The results indicated that mothers of aggressive boys do share the propensity to infer hostility in ambiguous situations and may, in effect, model a hostile attributional bias. Mothers of aggressive boys failed to differentiate ambiguous from hostile situations and were as likely to infer hostile intentions in ambiguous as in hostile situations. The results also suggest a generalized tendency on the part of mothers of aggressive boys to infer negative motives and/or dispositions when accounting for the noxious behavior of their sons. Further, for the aggressive boys, the hostile attributional bias was evident with both peers and teachers. The presence of a hostile attribution was predictive of an aggressive response for the aggressive boys. Even in the face of clearly hostile, provocative behavior, nonaggressive boys were less likely to offer aggressive solutions than aggressive boys.The authors acknowledge the contribution of the staff from the Division of Child and Adolescent Psychiatry and Emergency Medicine, Department of Pediatrics, Emory University School of Medicine, and Grady Health Systems for their assistance and support in conducting this study.     

A timing-specific memory distortion effect in young children

It has been suggested that there are systematic distortions in children's memory for temporal durations, such that children's memory is not just less accurate than that of adults but qualitatively different. Experiment 1 replicated the memory distortion effect by demonstrating developmental change in the tendency to confuse a reference duration with one that is shorter rather than longer than it. When the long-term memory demands of the task were reduced by providing reminders of the reference duration on every trial, there were no such qualitative changes in error patterns (Experiment 2). Further evidence for developmental changes in memory distortion was found in the temporal generalization task of Experiment 3, in which stimuli were spaced logarithmically rather than linearly. In Experiment 4, a similar distortion pattern was absent in a task in which children made judgments about the pitch rather than the duration of stimuli, suggesting the effect may be specific to time estimation.     

Effects of Training Goals and Goal Orientation Traits on Multidimensional Training Outcomes and Performance Adaptability

This research examined the effects of mastery vs. performance training goals and learning and performance goal orientation traits on multidimensional outcomes of training. Training outcomes included declarative knowledge, knowledge structure coherence, training performance, and self-efficacy. We also examined the unique impact of the training outcomes on performance adaptability by predicting generalization to a more difficult and complex version of the task. The experiment involved 60 trainees learning a complex computer simulation over 2 days. The research model posited independent effects for training goals relative to goal orientation traits and independent contributions of training outcomes to the performance adaptability of trainees. The findings were consistent with the proposed model. In particular, self-efficacy and knowledge structure coherence made unique contributions to the prediction of performance adaptability after controlling for prior training performance and declarative knowledge. Implications and extensions are discussed. Copyright 2001 Academic Press.     

Writing SMARTER goals for professional learning and improving classroom practices

Writing SMART Goals has recently become an integral part of the landscape of teacher professional learning in Australian schools, including both teacher professional development and performance management in classroom practices. This paper discusses the origins of SMART Goals and the diverse terms and definitions associated with such goal setting. Anecdotal evidence suggests that for some teachers, writing personal, professional or teaching and learning goals may be a daunting task. For school leadership teams, these goals often are the basis for operationalising school improvement over time. We make a case for clarity with SMART Goals within the context of each school, as interpreted and supported by school principals and leadership teams working with their staff. This paper concludes with some tentative suggestions for school leaders intended to improve SMART Goals, and teacher professional learning, over time. We hope this clarification and our suggestions support writing more effective learning goals for both teachers and students over time.     

Converging measures of workload capacity

Does processing more than one stimulus concurrently impede or facilitate performance relative to processing just one stimulus? This fundamental question about workload capacity was surprisingly difficult to address empirically until Townsend and Nozawa (1995) developed a set of nonparametric analyses called systems factorial technology. We develop an alternative parametric approach based on the linear ballistic accumulator decision model (Brown &; Heathcote, 2008), which uses the model’s parameter estimates to measure processing capacity. We show that these two methods have complementary strengths, and that, in a data set where participants varied greatly in capacity, the two approaches provide converging evidence.     

Strategic encoding and retrieval processes in verbal recall among middle-aged and older adults

The authors used an analysis of individual differences to examine the role of executive control in strategic encoding and retrieval in verbal recall. Participants enrolled in the Louisiana Healthy Aging Study completed measures of working memory (WM), cognitive status, vocabulary, and free recall of words. Indices of clustering in free recall were calculated to permit inferences on strategic encoding and retrieval processes. We hypothesized that WM would be more strongly associated with strategic encoding and retrieval metrics than vocabulary based on the assumption that successful remembering requires executive control in WM. Regression analyses, together with a variance portioning procedure, confirmed that WM had comparable levels of unique and shared variance with the strategic encoding and retrieval metrics, and both exceeded vocabulary. Theoretical and clinical implications of these data are considered, with the suggestion of future research in lifespan samples as opposed to exclusively young adult or older adult samples.     

Suicide Attempt Self-Injury Interview (SASII): development, reliability, and validity of a scale to assess suicide attempts and intentional self-injury

The authors describe the development of the Suicide Attempt Self-Injury Interview (SASII), an instrument designed to assess the factors involved in nonfatal suicide attempts and intentional self-injury. Using 4 cohorts of participants, authors generated SASII items and evaluated them with factor and content analyses and internal consistency statistics. The final measure was assessed for reliability and validity with collateral measures. The SASII assesses variables related to method, lethality and impulsivity of the act, likelihood of rescue, suicide intent or ambivalence and other motivations, consequences, and habitual self-injury. The SASII was found to have very good interrater reliability and adequate validity.     

A critical test of the failure-to-engage theory of task switching

When people switch between two tasks, their performance on each is worse than when they perform that task in isolation. One theory of this “switch cost” is the failure-to-engage (FTE) theory, which posits that observed responses are a simple mixture of prepared and unprepared response strategies. The probability that participants use prepared processes can be manipulated experimentally (e.g., by changing preparation time). The FTE theory is a binary mixture model and therefore makes a strong prediction about the existence of fixed points in response time distributions. We found evidence contradicting this prediction, using data from 20 participants in a standard task-switching paradigm. In this article, we examine reasons for the failure of the FTE theory, and we demonstrate that a generalized version of FTE theory accommodates our data.     

Effects on WAIS-III performance IQ (PIQ) and full scale IQ (FSIQ) when object assembly is substituted for each standard performance scale subtest

According to the WAIS-III Administration and Scoring Manual, Object Assembly (OA) may be substituted for any spoiled Performance subtest. This assertion has not been evaluated in a clinical sample. The present investigation reports differences that resulted in Performance IQ (PIQ) and Full Scale IQ (FSIQ) when OA replaced each of the Performance subtests. Participants were 47 referrals for neuropsychological assessment (age M = 45.98 years, SD = 9.82; education M = 13.82 years, SD = 2.78). Results indicated that OA may replace any Performance subtest without seriously altering the summary scores. Differences between the standard IQs and OA-based composites were < 2 points for PIQ and < 1 point for FSIQ. More than 90% of the OA-based composites fell within the 90% confidence limits of the corresponding IQ.
