Characterising the Personality of the Public Safety Offender and Non‐offender using Decision Trees: The Case of Colombia

The aim of this paper was to create a decision tree (DT) to identify personality profiles of offenders against public safety. A technique meeting this requirement was proposed that uses the C4.5 algorithm to derive decision rules for personality profiling of public safety offenders. The Mini‐Mult test was used to measure the personality profiles of 238 individuals. With the test results as our database, a C4.5 DT was applied to construct rules that classify each profile into one of two groups, those without and those with records of offences against public safety. The model correctly classified 80% of the personality profiles and delivered a set of decision rules for distinguishing the profiles by group, and the principal personality profiles were interpreted. We conclude that DTs are a promising technique for analysing personality profiles by their offender or non‐offender status. Finally, we believe that the development of a classifying model using DT may have practical applications in the Colombian prison system. Copyright © 2016 John Wiley & Sons, Ltd.

Generalized Information Theory Meets Human Cognition: Introducing a Unified Framework to Model Uncertainty and Information Search

Searching for information is critical in many situations. In medicine, for instance, careful choice of a diagnostic test can help narrow down the range of plausible diseases that the patient might have. In a probabilistic framework, test selection is often modeled by assuming that people's goal is to reduce uncertainty about possible states of the world. In cognitive science, psychology, and medical decision making, Shannon entropy is the most prominent and most widely used model to formalize probabilistic uncertainty and the reduction thereof. However, a variety of alternative entropy metrics (Hartley, Quadratic, Tsallis, Rényi, and more) are popular in the social and the natural sciences, computer science, and philosophy of science. Particular entropy measures have been predominant in particular research areas, and it is often an open issue whether these divergences emerge from different theoretical and practical goals or are merely due to historical accident. Cutting across disciplinary boundaries, we show that several entropy and entropy reduction measures arise as special cases in a unified formalism, the Sharma–Mittal framework. Using mathematical results, computer simulations, and analyses of published behavioral data, we discuss four key questions: How do various entropy models relate to each other? What insights can be obtained by considering diverse entropy models within a unified framework? What is the psychological plausibility of different entropy models? What new questions and insights for research on human information acquisition follow? Our work provides several new pathways for theoretical and empirical research, reconciling apparently conflicting approaches and empirical findings within a comprehensive and unified information‐theoretic formalism.     

Top-down selective visual attention: A neurodynamical approach

We propose a system of interconnected modules consisting of populations of neurons for modelling the underlying mechanisms involved in selective visual attention. We demonstrate that it is plausible to build a neural system for visual search, which works across the visual field in parallel, but, due to the intrinsic dynamics of the system, resembles apparent modes of visual attention, namely the serial focal and the parallel spread over the space mode. Thus, neither explicit serial focal search nor saliency maps need to be assumed. A focal attentional spotlight is not included in the system but rather focal attention emerges due to the convergence of the dynamic behaviour of the neural networks. The dynamics of the system can be interpreted as a mechanism for routing information from the sensory input.     

Cognitive and Ideological Aspects of Divine Anthropomorphism

After overstressing the experiential andsui generisaspects of religion, recent scholarship has returned to the exploration of the cognitive dimensions of religious phenomena (while still neglecting their ideological and evolutionary aspects). This article explores the cognitive aspects of divine anthropomorphism, approaching anthropomorphism as a metaphor for human agency. At the same time, the ideological aspects of anthropomorphic representations are studied in the context of political centralization and the emergence of kingship, seeking to clarify the connections between anthropomorphism and basileomorphism.     

Perception of Creativity and Game Intelligence in Soccer

A questionnaire was used to investigate the perception of creativity and game intelligence of coaches (n = 34, mean age 28.6 with an average of 14.3 years of experience) and players (n = 118, belonging to the ranks U-15 and U-19). Analyses indicated that there were statistically significant differences in most creative concepts inherent in the perception of creativity on the part of coaches. The results for the perception of the players showed that there were statistically significant differences in the importance attached to creativity and game intelligence. Apparently coaches mostly associate the creativity in soccer to a kind of magical thinking, adding also the game intelligence to the ability of rationality, problem solving, and decision. There was a strong correlation between creativity and game intelligence for the players.     

Verisimilitude and Belief Change for Conjunctive Theories

Theory change is a central concern in contemporary epistemology and philosophy of science. In this paper, we investigate the relationships between two ongoing research programs providing formal treatments of theory change: the (post-Popperian) approach to verisimilitude and the AGM theory of belief change. We show that appropriately construed accounts emerging from those two lines of epistemological research do yield convergences relative to a specified kind of theories, here labeled “conjunctive”. In this domain, a set of plausible conditions are identified which demonstrably capture the verisimilitudinarian effectiveness of AGM belief change, i.e., its effectiveness in tracking truth approximation. We conclude by indicating some further developments and open issues arising from our results.     

Treating chronic worry: Psychological and physiological effects of a training programme based on mindfulness

The present study examines psychological and physiological indices of emotional regulation in non-clinical high worriers after a mindfulness-based training programme aimed at reducing worry. Thirty-six female university students with high Penn State Worry Questionnaire scores were split into two equal intervention groups: (a) mindfulness, and (b) progressive muscle relaxation plus self-instruction to postpone worrying to a specific time of the day. Assessment included clinical questionnaires, daily self-report of number/duration of worry episodes and indices of emotional meta-cognition. A set of somatic and autonomic measures was recorded (a) during resting, mindfulness/relaxation and worrying periods, and (b) during cued and non-cued affective modulation of defence reactions (cardiac defence and eye-blink startle). Both groups showed equal post-treatment improvement in the clinical and daily self-report measures. However, mindfulness participants reported better emotional meta-cognition (emotional comprehension) and showed improved indices of somatic and autonomic regulation (reduced breathing pattern and increased vagal reactivity during evocation of cardiac defense). These findings suggest that mindfulness reduces chronic worry by promoting emotional and physiological regulatory mechanisms contrary to those maintaining chronic worry.     

Why are Girls Less Physically Aggressive than Boys? Personality and Parenting Mediators of Physical Aggression

The primary goal of the present analysis was todetermine whether the commonly observed genderdifference in physical aggression could be accounted forby gender differences in selected personality and social contextual factors. Eighty-nineadolescents (M age = 16.0; 52% female; 53%European-Americans, 38% Latinos)completed self-reportmeasures, including sympathy (empathic concern andperspective taking) and parental involvement (support andmonitoring). Mediation analyses revealed that relativelyhigh levels of both empathic concern and parentalmonitoring accounted for relatively low levels ofphysical aggression. In addition, sympathy (for males)and parental involvement (males and females) werenegatively related to physical aggression. Discussionfocused on theoretical and practical implications of these findings.     

Regional cerebral blood flow response in a patient with remitted global amnesia

A case of remitted global amnesia, believed to have residual left medial temporal lobe damage, is tested by the same recognition memory paradigm used by Wood, Taylor, et al. in the previous paper. On two different testing occasions, once using an intentional and once an incidental memory procedure, the patient's right occipital flows were inversely correlated with memory accuracy and the values were very close to the regression line for 10 normals relating occipital flow to memory accuracy. The left occipital flows did not fit the regression line, however. The results were interpreted as consistent with the notion that occipital flow is inversely related to medial temporal lobe activation. Another surprising feature of this case is the unexpected persistence of amnesia for a period from about 5 to 10 years before her episode to about 2 weeks after the episode, with recovery of memory functioning for the period since that time.
