Hemispheric functions in the processing of agent-patient information.

Left and right hemisphere processing capabilities for pictorial information about agent (performer of an action) and patient (recipient of an action) relations were assessed in a tachistoscopic study. Subjects were presented pictures in either the right or the left visual field depicting an agent-action-patient event. They were asked to locate which side of the drawing contained the agent and, in separate trials, which side contained the patient. Reaction times to locate the agent were significantly faster than to locate the patient, regardless of the field of presentation. The results are discussed in terms of a general nonlinguistic processing constraint that favors agent information. It is suggested that this processing asymmetry may underlie syntactic asymmetries regarding the expression of agents and patients in language.

Predicting developmental deficiencies at the age of four based on data from the first seven months of life

The study examines very young children with the aim of identifying precursors of developmental problems during the first 7 months of age. Information from screening and observations in the birth clinic, in the first level of health care, and from parents was collected on five different occasions. The information that was included concerning the child and family was defined as either optimal or nonoptimal. At the age of 4 years, a clinical group was identified (11.1% of the total population). Logistic regression analyses were performed to detect risk factors. Twenty‐one precursors were used to create a screening questionnaire that provided useful information (sensitivity = 56.1%, specificity = 98.8%) for predicting developmental problems of the children. The contribution of sociodemographic data was significant; medical information was less significant. The highest prediction rate surprisingly was found in the moderate clinical subgroup (62.1%), compared to the group with more severe problems that had a slightly lower rate (46.7%). The conclusion of the study is that it is possible to detect infants in need of early intervention using a continuous process of observation and screening.     

Adult age differences in the realism of confidence judgments: overconfidence, format dependence, and cognitive predictors

Realistic confidence judgments are essential to everyday functioning, but few studies have addressed the issue of age differences in overconfidence. Therefore, the authors examined this issue with probability judgment and intuitive confidence intervals in a sample of 122 healthy adults (ages: 35-40, 55-60, 70-75 years). In line with predictions based on the na?ve sampling model (P. Juslin, A. Winman, & P. Hansson, 2007), substantial format dependence was observed, with extreme overconfidence when confidence was expressed as an intuitive confidence interval but not when confidence was expressed as a probability judgment. Moreover, an age-related increase in overconfidence was selectively observed when confidence was expressed as intuitive confidence intervals. Structural equation modeling indicated that the age-related increases in overconfidence were mediated by a general cognitive ability factor that may reflect executive processes. Finally, the results indicated that part of the negative influence of increased age on general ability may be compensated for by an age-related increase in domain-relevant knowledge.     

The transportability of multisystemic therapy to Sweden: short-term results from a randomized trial of conduct-disordered youths

This randomized clinical trial assessed the effectiveness of multisystemic therapy (MST) for 156 youths who met the diagnostic criteria for conduct disorder. Sweden's 3 largest cities and 1 small town served as the recruiting area for the study. A mixed factorial design was used, with random allocation between MST and treatment as usual groups. Assessments were conducted at intake and 7 months after referral. With an intention-to-treat approach, results from multiagent and multimethod assessment batteries showed a general decrease in psychiatric problems and antisocial behaviors among participants across treatments. There were no significant differences in treatment effects between the 2 groups. The lack of treatment effect did not appear to be caused by site differences or variations in program maturity. MST treatment fidelity was lower than that of other studies, although not clearly related to treatment outcomes in this study. The results are discussed in terms of differences between Sweden and the United States. One difference is the way in which young offenders are processed (a child welfare approach vs. a juvenile justice system approach). Sociodemographic differences (e.g., rates of poverty, crime, and substance abuse) between the 2 countries may also have moderating effects on the rates of rehabilitation among young offenders.

Who is the Lifelong Learner? Globalization, Lifelong Learning and Hermeneutics

The aim of this essay is to elaborate on the inner connection between three such diverse entities as lifelong learning, globalization and hermeneutics. After placing lifelong learning in a societal context framed by globalization, my intention is to reflect on the prerequisites for introducing a hermeneutical contribution to the understanding of lifelong learning. First, it is stated that globalization is the most profound horizon today for explaining the current interest we experience in both lifelong learning and hermeneutics. Second, from these links to on globalization, we can also expect to find new links between lifelong learning and hermeneutics. Third, the predominant configuration of lifelong learning according to the logics of globalization and virtues of flexibility is demonstrated, and thereafter criticized mainly from the perspectives of philosophical anthropology. Finally, an alternative configuration of meaning and identity formation in lifelong learning is proposed by utilizing a reformulated theory of interpretation made possible thanks to recent metamorphosis inside the hermeneutical tradition itself.

The Modes of Value

Contrary to the received view, decision theory is not primarily devoted to instrumental (ends-to-means) reasoning. Instead, its major preoccupation is the derivation of ends from other ends. Given preferences over basic alternatives, it constructs preferences over alternatives that have been modified through the addition of value object modifiers (modes) that specify probability, uncertainty, distance in time etc. A typology of the decision-theoretical modes is offered. The modes do not have (even extrinsic) value, but they transform the value of objects to which they are applied. A rational agent's total set of preferences should be coherent, but from this it does not follow that her preferences over mode-containing objects have to be derivable from her preferences over mode-free objects.     

Genetic probes of three theories of maternal adjustment: I. Recent evidence and a model.

Studies focusing on genetic and social influences on maternal adjustment will illumine mother's marriage, parenting, and the development of psychopathology in her children. Recent behavioral genetic research suggests mechanisms by which genetic and social influences determine psychological development and adjustment. First, heritable, personal attributes may influence individuals' relationships with their family members. These genetically influenced family patterns may amplify the effects of adverse, heritable personal attributes on adjustment. Second, influences unique to siblings may be the most important environmental determinants of adjustment. We derive three hypotheses on maternal adjustment from integrating these findings from genetic studies with other contemporary research on maternal adjustment. First, mother's marriage mediates the influence of her heritable, personal attributes on her adjustment. Second, mother's recall of how she was parented is partially genetically influenced, and both her relationships with her spouse and her child mediate the impact of these genetically influenced representations on her current adjustment. Third, characteristics of mother's spouse are important influences on difference between her adjustment and that of her sister's. These sibling-specific influences are unrelated to mother's heritable attributes. The current article develops this model, and [figure: see text] the companion article describes the Twin Mom Study that was designed to test it as well, as its first findings. Data from this study can illumine the role of family process in the expression of genetic influence and lead to specific family interventions designed to offset adverse genetic influences.     

Genetic probes of three theories of maternal adjustment: II. Genetic and environmental influences.

This is the first report of the Twin Mom Study, an investigation of three hypotheses concerning influences on maternal adjustment. These hypotheses concern the role of the marital and parent-child relationships in mediating genetic influences on maternal adjustment and on the importance of the mothers' marital partners as a specifiable source of influences on their adjustment not shared with their sisters. The study's sample of 150 monozygotic (MZ) twins and 176 dizygotic (DZ) twins was drawn randomly from the Swedish Twin Registry and is, with some small exceptions, likely to be representative of women in the Swedish population. The sample included the marital partners of these twins and their adolescent children. Self-report and coded videotapes were a source of information about family process. Results reported in this first report focus on comparability of American and Swedish samples on scales measuring psychiatric symptoms, and on an analysis of genetic and environmental influences on nine measures of mothers' adjustment. Results suggest comparability between the US and Sweden. Genetic influences were found for all measures of adjustment, particularly in the psychological manifestations of anxiety and for smoking. The pattern of findings also underscored the importance of influences unique to each sibling within the twin pair, thus focusing attention on the potential role of marital partners in maternal adjustment. Results also suggested that experiences shared by the twin sisters, experiences unrelated to their genetic similarity, may influence their fearfulness and alcohol consumption. Our model did not include these influences and thus must be amended.
