Executive Function as an Interaction-Dominant Process

Traditional theories of psychology define the cognitive system as composed of insular, encapsulated components, controlled by a central executive. An alternative hypothesis suggests that cognitive control arises from the complex interaction among temporal scales of activity within the system. We examined the hand motions of preschool-age participants gathered during an executive-function task, card sorting, for evidence of multiplicative interactions across temporal scales. The time series of hand motions were submitted to iterated amplitude adjusted Fourier transformation (IAAFT), a surrogate data analysis technique that removes nonlinear, multiscale dependencies while preserving the linear structure of the time series. We found that removing multiscale effects via IAAFT led to a significant change in the width of the multifractal spectrum, an indicator of multiplicative interactions. The results suggest that cognitive control may arise from the interactions among temporal scales of activity within the system rather than as the result of a central executive.     

Prevalence of Anxiety and Depression in Australian Adolescents: Comparisons with Worldwide Data

Data from two Australian studies were combined so that the prevalence of anxiety and depression in a large, normative sample of Australian adolescents could be investigated. The combined sample comprised 1,299 adolescents randomly selected from metropolitan and country schools in Melbourne, a large Australian city. The data were examined in order to ascertain the percentages of adolescents who scored above the clinical cut-off on two self-report instruments-the Revised Children's Manifest Anxiety Scale (C. R. Reynolds & B. 0. Richmond, 1985) and the Reynolds Adolescent Depression Scale (W. M. Reynolds, 1986). The results of these analyses were then compared with previously reported prevalence rates from studies worldwide. This comparison revealed striking differences in the prevalence of anxiety and depression across different countries and cultures. Limitations attributable to different self-report measures and imposed-etic approaches are discussed. Issues pertaining to social and political climate are also raised.     

Pragmatic Psychodynamic Psychotherapy—Bridging Contemporary Psychoanalytic Clinical Practice and Evidence-Based Psychodynamic Practice

Pragmatic psychodynamic psychotherapy (PPP; Summers & Barber, 2009 Barber, J. P. 2009. Toward a working through of some core conflicts in psychotherapy research. Psychother. Res, 19(1): 1–12. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) describes the therapeutic principles and approaches found in many forms of manualized psychodynamic psychotherapies, which are being used in research studies with the aim of building an evidence-based psychodynamic practice. This article focuses on one such treatment, Supportive-expressive psychotherapy (SEP; Luborsky 1984), which employs the Core Conflictual Relationship Theme (CCRT) method to formulate core interpersonal problems and treatment goals and identify therapeutic interventions. To illustrate SEP, we describe the 40-session treatment of a patient who met diagnostic criteria for several personality disorders. The case illustrates how complex ego-syntonic character pathology is expressed in CCRT terms and worked through in the transference, gradually becoming ego-dystonic and amenable to modification. In this case, the patient became more aware of his interpersonal wishes and vulnerability. Although his anxiety increased somewhat, he had an improvement in psychosocial functioning.     

Fairness lies in the heart of the beholder: How the social emotions of third parties influence reactions to injustice

The present research explores third parties’ (e.g., jurors, ombudsmen, auditors, and employees observing others’ encounters) ability to objectively judge fairness. More specifically, the current research suggests that third parties’ justice judgments and reactions are biased by their attitudes toward the decision recipient and, in particular, the affective aspect of those attitudes as characterized by their felt social emotions. We explore how the congruence of a social emotion (i.e., the extent to which the emotion reflects feeling a subjective sense of alignment with the target of the emotion) can influence their evaluations of recipients’ decision outcomes. The five studies presented show that congruence can lead third parties to react positively to objectively unfair decision outcomes and, importantly, that the influence of social emotions on subjective justice judgments drive third party reactions to decisions, decision makers, and even national policies.     

Ecosystemic Structural Family Therapy: Theoretical and Clinical Foundations

Ecosystemic structural family therapy (ESFT) is a systemic, strength-based, and trauma-informed family therapy model that has evolved from structural family therapy (SFT; Minuchin in Families and family therapy, Harvard University Press, Cambridge, 1974). ESFT is an evidenced-based family therapy approach designed to intervene with families of children who are experiencing behavioral health problems and are at the risk of out-of-home placement. In this article we review the theoretical, applied, and empirical evolution of ESFT relative to extant SFT models. ESFT is based on the fundamental assumption that child, parental, and marital functioning are inextricably linked to their relational environment. Five interrelated constructs guide ESFT therapists in their understanding of clinical problems: family structure; family and individual emotional regulation; individual differences (e.g., historical, biological, cultural, developmental); affective proximity; and family development (Gehart 2010). ESFT has an extensive evaluation history dating back to the 1980s involving over 4,000 families in 39 different sites. While ESFT is considered evidence-based, it might be more consistent with “Practice-Based Evidence” given its long, extensive, and successful, history in the child mental health system in Pennsylvania.     

A Change of Perspective: Seeing Through Children at the Front of the Classroom, to Seeing Children from the Back of the Classroom

This article considers a noted trend by teacher educators at a South African University where student teachers seem to have very little connection with children they teach on their teaching practicals. This lack of engagement and ability to see individual children that are being taught and respond to them is the focus of the paper. The paper considers how such a circumstance may come into being by looking at socio-historical practices in education through a Foucauldian lens using the notions of government and governmentality. Ways in which people were managed and dominant forms of knowledge and being are in tension with curricular shift that construct children as competent and able. It then proposes that within teacher education a shift of perspective is needed in enabling students to ‘look’ at the children in their classrooms in a deeper, more engaged way. This draws from research methods that use observation as for researchers to understand participants through their eyes (Hatch A, Doing qualitative research in education settings, State University of New York Press, Albany, 2002). Three examples are given from classroom observations as a way of exploring what close observations of children can teach us about children’s needs and interests. The paper concludes with a general framework students might draw on that places children as the focus in the classroom.     

Models of data and theoretical hypotheses: a case-study in classical genetics

Linkage (or genetic) maps are graphs, which are intended to represent the linear ordering of genes on the chromosomes. They are constructed on the basis of statistical data concerning the transmission of genes. The invention of this technique in 1913 was driven by Morgan’s group’s adoption of a set of hypotheses concerning the physical mechanism of heredity. These hypotheses were themselves grounded in Morgan’s defense of the chromosome theory of heredity, according to which chromosomes are the physical basis of genes. In this paper, I analyze the 1919 debate between William Castle and Morgan’s group, about the construction of genetic maps. The official issue of the debate concerns the arrangement of genes on chromosomes. However, the disputants tend to carry out the discussions about how one should model the data in order to draw predictions concerning the transmission of genes; the debate does not bear on the data themselves, nor does it focus on the hypotheses explaining these data. The main criteria that are appealed to by the protagonists are simplicity and predictive efficacy. However, I show that both parties’ assessments of the simplicity and predictive efficacy of different ways of modeling the data themselves depend on background theoretical positions. I aim at clarifying how preference for a given model and theoretical commitments articulate.     

Spearman's law of diminishing returns: A statistical artifact?

Spearman's Law of Diminishing Returns (SLODR) is the idea that the structure of human cognitive ability is more differentiated and g a weaker determinant of cognitive performance at higher levels of ability. In this study, we distinguish between ‘traditional’ methods of testing SLODR and ‘contemporary’ methods of testing SLODR. It is the former set of methods from which the vast majority of the evidence base for SLODR derives. We demonstrated that it is easy to mimic SLODR and reverse SLODR effects in these traditional methods of assessing SLODR by using data with skewed observed variable distributions. The skewness magnitudes did not need to be large to produce these effects and they fell well within the range of values that are usually considered unproblematic for parametric statistic analysis. In simulated datasets, positive subtest skewness resulted in SLODR and negative subtest skewness resulted in reverse SLODR. In contemporary methods of testing SLODR, non-linear g-loadings or a skewed g are assumed to reflect evidence for SLODR. When we applied contemporary methods of testing SLODR to these data, there was evidence of heteroscedastic residuals but no evidence of non-linear g-loadings or skewed g distributions. We broadly replicated the effects of subtest skew from these simulated datasets in real data from the Minnesota Study of Twins Reared Apart. Results imply that traditional methods of assessing SLODR cannot distinguish between effects due to subtest characteristics that have nothing to do with differences in ability structure at different levels of g and true SLODR effects. This calls into question the empirical support for SLODR.
