Executive functioning: Developmental consequences on adolescents with histories of maltreatment

Research suggests that children exposed to maltreatment have deficits in executive functioning (EF) but few studies have focused on the adolescent age group. We investigated whether maltreated adolescents had lower EF abilities compared to a group of non‐maltreated adolescents. Forty adolescents with histories of child maltreatment, together with a comparison group of 40 non‐maltreated adolescents matched for age, completed a comprehensive battery of EF tasks. Hierarchical multiple regression analyses, controlling for IQ, were carried out using each of the EF measures as dependent variables to examine group differences. Maltreated adolescents had significantly lower performance than non‐maltreated adolescents on tasks assessing executive loaded working memory, fluency, and inhibition, although switching was not impaired. Emotional and behavioural difficulties (EBD) were included in additional regression analyses to examine whether these variables would explain the group differences. The inclusion of EBD variables had some effect on group differences, as expected, but did not eliminate them. These findings support the theory that impairments in EF may be one underlying reason why adolescents with histories of maltreatment struggle to cope both inside and outside the classroom.     

Infants' use of social partnerships to predict behavior

The experiences of social partners are important motivators of social action. Can infants use such experiences to make predictions about how social agents will behave? Sixteen‐month‐old infants were introduced to two social pairs. Initial events established within‐pair cooperation as well as between‐pair conflict involving an individual from each pair. Following these events, infants looked longer when between‐pair members who had never previously interacted now cooperated – instead of conflicted – with each other. Thus, infants tracked the third‐person allegiances and inferred that the conflict would generalize across social partnerships. These findings demonstrate a critical feature of early social cognition and promote needed, further research on the role of social allegiances in social cognition across development.     

SCIENCE'S CONCEPTION OF HUMAN BEINGS AS A BASIS FOR MORAL THEORY

Abstract. Niels Bohr stated, and Werner Heisenberg reiterated, that “in the great drama of existence we ourselves are both actors and spectators.” Their emphasis stems from the fact that the entry of human beings into physics as actors constitutes the most fundamental philosophical departure of twentieth‐century basic physics from its eighteenth‐ and nineteenth‐century forerunners. Those earlier theories claimed that our human conscious thoughts are mere witnesses to, or by‐products of, essentially mechanically determined brain processes. In stark contrast, certain conscious decisions that are made by human beings, but that are not determined by any known law, statistical or otherwise, enter irreducibly into orthodox contemporary physical theory. These actions are required to counteract effects of Heisenberg's Uncertainty Principle, which ordains that the physically described process of nature, acting alone, produces not a physical world of the kind we experience but rather a continuous smear of potential possible worlds of the kind we know. This contradiction between theory and experience is resolved in orthodox contemporary physical theory by bringing certain effects of our conscious human choices into the dynamics in essentially the way that we intuitively feel that our conscious intentions affect the physical world, namely, via the effects of our intentional efforts on our physically described bodies. The moral implications of this profound change in physics are discussed.     

How are habits formed: Modelling habit formation in the real world

To investigate the process of habit formation in everyday life, 96 volunteers chose an eating, drinking or activity behaviour to carry out daily in the same context (for example ‘after breakfast’) for 12 weeks. They completed the self‐report habit index (SRHI) each day and recorded whether they carried out the behaviour. The majority (82) of participants provided sufficient data for analysis, and increases in automaticity (calculated with a sub‐set of SRHI items) were examined over the study period. Nonlinear regressions fitted an asymptotic curve to each individual's automaticity scores over the 84 days. The model fitted for 62 individuals, of whom 39 showed a good fit. Performing the behaviour more consistently was associated with better model fit. The time it took participants to reach 95% of their asymptote of automaticity ranged from 18 to 254 days; indicating considerable variation in how long it takes people to reach their limit of automaticity and highlighting that it can take a very long time. Missing one opportunity to perform the behaviour did not materially affect the habit formation process. With repetition of a behaviour in a consistent context, automaticity increases following an asymptotic curve which can be modelled at the individual level.

Exploring Adoption with Clients: The Need for Adoption Education Within the Genetic Counseling Profession

Genetic counselors and other health professionals may encounter adoption during any counseling session. They must be skilled in using appropriate language and understand how to approach and discuss this topic with clients. A thorough knowledge of adoption as an option for clients facing a prenatal or postnatal diagnosis is necessary when presenting individuals with non-biased information needed for informed decision-making. However, three preliminary studies have demonstrated an absence of graduate education and lack of a professional knowledge base regarding this option (Mates 2008; Oksala 2007; Perry 2003). We discuss the impact of medical professionals’ preconceptions on client decision-making, increasing early identification of fetal anomalies, deficiency of adoption knowledge and resources, and the resulting need for genetic counselors and other health professionals to develop their skills in discussing adoption with clients.
