Decision making in dual-task environments: analysis of hemispheric competition effects

Performance degradations in multitasking situations have been reported frequently as a predictable effect of competition that arises from different processing demands whose hemispheric locations are too proximal. This model might be useful in explaining performance deficits in complex workplaces. To test this assertion, a laboratory study was designed to create an analogue of the processing demands required by a tactical decision-making task performed by 24 right-handed men. Vocalization, dichotic listening and decision-making performance were assessed under single- and dual-task conditions. The results were consistent with the predictions from hemispheric competition in the case of dichotic listening but not with vocalization. The results are discussed in terms of their implications for both research and systems design.     

The ‘Magical’ Effect of Integration on Event Memory

Only a handful of studies have extended our understanding of retrieval induced forgetting (RIF) during development and even fewer have tested for RIF effects outside word‐list paradigms. The purpose of these experiments was to: (i) examine how partial retrieval of a witnessed event would impact subsequent retrieval of that event in school‐aged children; and (ii) examine the robustness of semantic integration as a boundary condition on RIF. Two experiments were conducted using the three traditional phases of the RIF paradigm: study phase, practice phase, and test phase. We found clear evidence of RIF in event memory. There was also evidence of the robust impact that integration instructions have on minimizing RIF. Integration appears to not only have a dampening effect on RIF, but integration instructions may also influence how children process all aspects of an experience, regardless of whether a person is passively or actively part of the experience.Copyright © 2016 John Wiley & Sons, Ltd.     

Why do people show minimal knowledge updating with task experience: inferential deficit or experimental artifact?

Students generally do not have highly accurate knowledge about strategy effectiveness for learning, such as that imagery is superior to rote repetition. During multiple study-test trials using both strategies, participants' predictions about performance on List 2 do not markedly differ for the two strategies, even though List 1 recall is substantially greater for imagery. Two experiments evaluated whether such deficits in knowledge updating about the strategy effects were due to an experimental artifact or to inaccurate inferences about the effects the strategies had on recall. Participants studied paired associates on two study-test trials--they were instructed to study half using imagery and half using rote repetition. Metacognitive judgements tapped the quality of inferential processes about the strategy effects during the List 1 test and tapped gains in knowledge about the strategies across lists. One artifactual explanation--noncompliance with strategy instructions--was ruled out, whereas manipulations aimed at supporting the data available to inferential processes improved but did not fully repair knowledge updating.     

Social Information Processing Skills in Children with Histories of Heavy Prenatal Alcohol Exposure

Based on caregiver report, children with prenatal alcohol exposure have difficulty with social functioning, but little is known about their social cognition. The current study assessed the social information processing patterns of school-age children with heavy prenatal alcohol exposure using a paradigm based on Crick and Dodge’s reformulated six-stage model. Fifty-two children (aged 7–11) with and without heavy prenatal alcohol exposure were tested using a structured interview measure of social information processing involving 18 videotaped vignettes of children in group entry and provocation situations. Alcohol-exposed children displayed maladaptive processing patterns on the goal, response generation, and response evaluation steps in group entry situations, and encoding, attribution, response evaluation, and enactment steps during provocation situations. Children with heavy prenatal alcohol exposure also had difficulty on the Test of Problem Solving, and performance correlated with social information processing measures. Such difficulties may lead to problems in social functioning and warrant early intervention.     

The impact of Parkinson's disease on sequence learning: perceptual pattern learning and executive function

The current study examined the contribution of brain areas affected by Parkinson's disease (PD) to sequence learning, with a specific focus on response-related processes, spatial attentional control, and executive functioning. Patients with mild PD, patients with moderate PD, and healthy age-matched participants performed three tasks-a sequence learning task with a spatial pattern that was incidental to response selection, a spatial cuing task, and neuropsychological tests of executive function. Whereas moderate PD patients failed to show significant sequence learning, mild PD patients performed comparably with controls. Neither group of PD patients was impaired in the control of spatial attention. Sequence learning was correlated with neuropsychological measures of executive function but not with the ability to control spatial attention. These results suggest that the contribution of the brain areas affected by PD to sequence learning extends beyond motor learning to include the learning of perceptual patterns and involves executive function, including cognitive flexibility and set shifting.     

Predictors of Cancer Worry in Unaffected Women from High Risk Breast Cancer Families: Risk Perception is not the Primary Issue

Some women at increased familial risk of breast cancer experience elevated levels of cancer-specific worry, which can possibly act as a barrier to screening, and may be a significant factor in decisions regarding risk-reducing surgery. The aim of this study was to comprehensively examine predictors of cancer-specific worry in high risk women and to test a model which proposes that perceived breast cancer risk mediates the impact of other factors on worry. 1,437 unaffected women from high risk breast cancer families completed questionnaires and interviews. Path analysis was used to test the model of potential predictors of cancer worry, including familial, personal and psychological variables, mediated via perceived cancer risk. Levels of cancer-specific worry were generally low despite an average perceived risk of 50.3%. The goodness-of-fit of the proposed model was poor, explaining only 9% of the variance for perceived risk and 10% of the variance for cancer specific worry. An alternative model of a direct relationship between all of the predictor variables and cancer worry, explained 24% of the variation in cancer worry. General anxiety, perceived risk, the stressful impact of recent cancer related events, a relative risk greater than 10, being closer in age to the youngest breast cancer diagnosis in family, and knowledge of personal mutation status, all independently contributed to cancer worry. Addressing general affective responses, experiences of recent cancer related events, in addition to education about personal risk, should be considered in counselling women with elevated cancer worry. Risk perception appears to act independently of other factors in its formulation and impact on cancer worry. Further research on the way in which women come to perceive their risk is indicated.

The relationship between childhood abuse and adult personality disorder symptoms

This study assessed personality disorder symptomatology in a community sample of healthy adults without diagnosable DSM-IV-TR Axis I psychiatric disorders who reported a history of childhood abuse. Twenty-eight subjects with a history of moderate to severe physical, sexual, and/or emotional abuse according to the Childhood Trauma Questionnaire were compared to 33 subjects without an abuse history on symptoms of personality disorders. Subjects in the Abuse group were more likely to report subclinical symptoms of paranoid, narcissistic, borderline, antisocial, obsessive compulsive, passive-aggressive, and depressive personality disorders. These findings link reports of childhood abuse with symptoms of personality disorders in the absence of Axis I psychiatric disorders in a community sample of healthy adults.
