Predictors of quantitative and qualitative Halstead finger-tapping scores in low socioeconomic status school-age children.

Two hundred and thirteen low socioeconomic school-age children in grades 1 through 8 were administered the Halstead Finger Oscillation (or Tapping) Test (HFTT). All children were age appropriate for their grade in school and were not requiring special education services. Hierarchical multiple regression analysis revealed that a composite age/grade classification score, gender, and estimated level of intelligence accounted for approximately 40% of the variability in dominant and nondominant hand scores for these children (multiple R = .627, R(2) = +.393 for the dominant and multiple R = +.607, R(2) = +.368 for the nondominant hand). Only the age/grade level of the child (R(2) = .168) predicted the ability to inhibit adjacent finger movements when performing the HFTT task. Regional normative data for low socioeconomic school-age children are presented. Neurodevelopmental changes in the cortical and subcortical systems underlying finger movement may account for some of the variability observed in children when performing the HFTT.     

Autonomy or Dependence – or Both?: Perspectives from Bangladesh

The idea of personal autonomy is central to many accounts of eudaimonic well-being. Yet it is often criticized as a Western concept celebrating individualism and independence over group obligations and interdependence or dependence. This paper rejects this view and argues that coherent accounts of autonomy must always recognize the interdependence of people in groups, and that autonomy can coexist with substantial relationships of dependence. It illustrates this drawing on evidence from Bangladesh, a poor country usually absent from cross-cultural studies and one where personal relationships of hierarchy and dependence are endemic. Argument and evidence are presented showing the coexistence of personal autonomy and dependence, and the relationship between collective action and autonomy. We also address some of the specific problems encountered in researching autonomy in a social context where it is mainly expressed in relational forms. We conclude that autonomy can be directed toward both personal and social goals, and can be enacted individually, or by participation in groups. Autonomy is a universal psychological need but its expression is always contextual. ESRC Research Group on Wellbeing in Developing Countries     

Order‐constrained linear optimization

Despite the fact that data and theories in the social, behavioural, and health sciences are often represented on an ordinal scale, there has been relatively little emphasis on modelling ordinal properties. The most common analytic framework used in psychological science is the general linear model, whose variants include ANOVA, MANOVA, and ordinary linear regression. While these methods are designed to provide the best fit to the metric properties of the data, they are not designed to maximally model ordinal properties. In this paper, we develop an order‐constrained linear least‐squares (OCLO) optimization algorithm that maximizes the linear least‐squares fit to the data conditional on maximizing the ordinal fit based on Kendall's τ. The algorithm builds on the maximum rank correlation estimator (Han, 1987, Journal of Econometrics, 35, 303) and the general monotone model (Dougherty & Thomas, 2012, Psychological Review, 119, 321). Analyses of simulated data indicate that when modelling data that adhere to the assumptions of ordinary least squares, OCLO shows minimal bias, little increase in variance, and almost no loss in out‐of‐sample predictive accuracy. In contrast, under conditions in which data include a small number of extreme scores (fat‐tailed distributions), OCLO shows less bias and variance, and substantially better out‐of‐sample predictive accuracy, even when the outliers are removed. We show that the advantages of OCLO over ordinary least squares in predicting new observations hold across a variety of scenarios in which researchers must decide to retain or eliminate extreme scores when fitting data.     

TACIT: An open-source text analysis,crawling, and interpretation tool

As human activity and interaction increasingly take place online, the digital residues of these activities provide a valuable window into a range of psychological and social processes. A great deal of progress has been made toward utilizing these opportunities; however, the complexity of managing and analyzing the quantities of data currently available has limited both the types of analysis used and the number of researchers able to make use of these data. Although fields such as computer science have developed a range of techniques and methods for handling these difficulties, making use of those tools has often required specialized knowledge and programming experience. The Text Analysis, Crawling, and Interpretation Tool (TACIT) is designed to bridge this gap by providing an intuitive tool and interface for making use of state-of-the-art methods in text analysis and large-scale data management. Furthermore, TACIT is implemented as an open, extensible, plugin-driven architecture, which will allow other researchers to extend and expand these capabilities as new methods become available.     

Modified TC for MICA offenders: crime outcomes

The study randomly assigned male inmates with co-occurring serious mental illness and chemical abuse (MICA) disorders to either modified therapeutic community (MTC) or mental health (MH) treatment programs. On their release from prison, MICA inmates who completed the prison MTC program could enter the MTC aftercare program. The results, obtained from an intent-to-treat analysis of all study entries, showed that inmates randomized into the MTC group had significantly lower rates of reincarceration compared with those in the MH group. The results also show that differences between the MTC + aftercare and comparison group across a variety of crime outcomes (i.e. any criminal activity, and alcohol or drug related criminal activity) are consistent and significant, and persist after an examination of various threats to validity (e.g. initial motivation, duration of treatment, exposure to risk). This study provides some support for the effectiveness of the prison TC only condition. The findings are encouraging and consonant with other studies of integrated prison and aftercare TC programs for substance abusing non-MICA offenders, although qualified by the possibility that selection bias (i.e. differences in motivation on entry into aftercare) may be operating. Nevertheless, given the available evidence and the need for effective programming for MICA offenders, program and policy makers should strongly consider developing integrated prison and aftercare modified TC programs for MICA offenders.     

Towards the feeling of emergence

Emergence is a multi-dimensional notion; the meanings it has acquired span the mythopoetic to the scientific, especially as found in complex systems. Examples of emergence in Navaho and Egyptian imagery underscore its diverse cultural origins and applications as well as suggesting an underlying archetypal quality to the core concept. A brief overview of the use of this term in science starting in the 17th century helps to locate the roots of modern emergent views in the philosophy of Leibniz. Jung's own use of early systems approaches was a part of his formulations of a 'third' position associated with the transcendent function. As this paper was delivered at the 50th anniversary conference of the Journal of Analytical Psychology, aspects of the emergence of the Journal within the contents of the first issue are explored. Attention is drawn to several articles, especially a case of brief child therapy done by Robert Moody. His approach to working his case is strikingly modern and vividly demonstrates principles of emergence within the clinical setting. Following this there is a discussion of some neuroscientific research on neural body maps, pointing to the experience of feelings as an emergent process. It is suggested that feelings derive from phase transitions in the brain's body mapping states. A reconsideration of a seeming impasse in the case described by Moody leads instead to a view of the initial phase of treatment as a pre-critical period. Research findings on mirror neurons are presented in terms of the feeling of empathy. Subjective feelings are then shown to be associated with moments of emergence, especially surprise and curiosity, exemplified by a case from the author's practice.     

Image analysis of small animal feeding behavior

The optimal design of behavioral experiments includes measures to minimize observer bias while maximizing researcher efficiency. To this end, we have developed a reliable, autonomous monitor of animal feeding behavior. Previous studies of caterpillar (Manduca sexta) feeding have relied on human observation for visual evaluation of food consumption at specific time points over the course of several hours. This method is eliminated by our newbehavior rig, which collects data automatically. Individual animals are monitored via CCD cameras activated in sequence by a computer. Images are obtained at preset time intervals using a frame grabber to capture still pictures from the cameras. Subsequently, images are analyzed using software written in MatLab to determine food selection and quantify consumption.     

Multivariate Extreme Value Distributions and Coverage of Ranking Probabilities

The main result in this paper is that the class of multivariate extreme value distributions, when used as random utility models, can approximate all ranking probability distributions. This extends Theorem 1 of Dagsvik (1995). Copyright 2001 Academic Press.
