Investigating route learning,metacognition, and beacon-based strategies using virtual environments

IntroductionDominant theories of wayfinding may have underestimated the ease with which adults can learn a route, even with minimal exposure to that route.ObjectivesIn this paper we present three different experiments to provide a comprehensive picture of whether adults can learn complex routes consisting of a number of choicepoints, and if so, what strategies they might be employing to do so.Methodand results We found that adults could learn a 15-junction route after only a single experience of the route (Experiment 1) but that they underestimated how good they would be at learning the 15-junction route (Experiment 2). In Experiment 3, we found that when learning a route made up of “T” shaped junctions, participants relied on a “beacon” strategy based on visual matching.ConclusionsCollectively, these findings suggest that adults can learn complex routes, even with as many as 15 choicepoints, very quickly and without the need for repeated exposure. These findings have implications for theories of wayfinding and call into question the need for repeated exposure.     

Personal values and unsanctioned aggression inherent in contact sports: The role of self-regulatory mechanisms,aggressiveness, and demographic variables

IntroductionTo date, research-examining factors related to the sociocognitive self-regulatory mechanisms governing unsanctioned aggression have received scant attention in applied sport psychology.ObjectiveA mediating model as influenced by various demographic variables was applied to explore the relationships between athletes’ personal values and their unsanctioned aggression directly and indirectly through the mediating role of resistive self-regulatory efficacy, moral disengagement, and aggressiveness.MethodA sample of 301 French competitors of different age (young: n = 200 and adult: n = 101), gender (male: n = 172 and female: n = 129), type of sport (high: n = 131 and low contact: n = 170), level of competition (beginner: n = 115, intermediate: n = 110, and advanced: n = 76), and length of practice (brief: n = 109, intermediate: n = 49, and extensive: n = 143) completed a questionnaire assessing the aforementioned variables.ResultsStructural equation modelling demonstrates that self-transcendence and self-enhancement values have only indirect negative and positive effects, respectively, on unsanctioned aggression through the full mediating effect of the mediators. Also, age, gender, and type of sport were predictive only of some personal values and mediators.ConclusionThese findings offer evidence that resistive self-regulatory efficacy, moral disengagement, and aggressiveness are mediators that fully govern the impact of athletes’ personal values and certain demographic variables on their unsanctioned aggression. Several limitations, implications and suggestions for further research are discussed.     

Network change point detection in resting-state functional connectivity dynamics of mild cognitive impairment patients

Background/Objective: This study aims to characterize the differences on the short-term temporal network dynamics of the undirected and weighted whole-brain functional connectivity between healthy aging individuals and people with mild cognitive impairment (MCI). The Network Change Point Detection algorithm was applied to identify the significant change points in the resting-state fMRI register, and we analyzed the fluctuations in the topological properties of the sub-networks between significant change points. Method: Ten MCI patients matched by gender and age in 1:1 ratio to healthy controls screened during patient recruitment. A neuropsychological evaluation was done to both groups as well as functional magnetic images were obtained with a Philips 3.0T. All the images were preprocessed and statistically analyzed through dynamic point estimation tools. Results: No statistically significant differences were found between groups in the number of significant change points in the functional connectivity networks. However, an interaction effect of age and state was detected on the intra-participant variability of the network strength. Conclusions: The progression of states was associated to higher variability in the patient's group. Additionally, higher performance in the prospective and retrospective memory scale was associated with higher median network strength.     

Algebras of Intervals and a Logic of Conditional Assertions

Intervals in boolean algebras enter into the study of conditional assertions (or events) in two ways: directly, either from intuitive arguments or from Goodman, Nguyen and Walker's representation theorem, as suitable mathematical entities to bear conditional probabilities, or indirectly, via a representation theorem for the family of algebras associated with de Finetti's three-valued logic of conditional assertions/events. Further representation theorems forge a connection with rough sets. The representation theorems and an equivalent of the boolean prime ideal theorem yield an algebraic completeness theorem for the three-valued logic. This in turn leads to a Henkin-style completeness theorem. Adequacy with respect to a family of Kripke models for de Finetti's logic, ukasiewicz's three-valued logic and Priest's Logic of Paradox is demonstrated. The extension to first-order yields a short proof of adequacy for Körner's logic of inexact predicates.     

Style in Philosophy: Part I

In this article, I attempt to restore the philosophical significance of that nonformalizable, noniterable, "singular' element of natural language that I call "style." I begin by critically addressing the exclusion of such instances of natural language by both semantics-oriented logical analysis and a restricted variation of structuralist linguistics. Despite the obvious advantages – with regard to style – of "pragmatic"approaches to language, such pragmatism merely returns to rule-determination in the guise of "normativity." Although style by definition resists any kind of rule-determination – whether posed in terms of semantics or intersubjective regulations of speech-acts – there can be no consideration of language that ignores the persistence of style in natural language. In terms of cognition, any discursive agent understands more than allowed by either semantics or speech-act theory. I ascribe this element of excessive signification to the role of style. My principal thesis is twofold: (1) a hermeneutic approach (exemplified by Schleiermacher) to literature should reveal the heuristically decisive role played by style in philosophy; and, more radically still, (2) style, in fact, may be crucially determinative of philosophical discourse in general. I suggest that a closer scrutiny of the lesser-known works of Ludwig Wittgenstein, conventionally regarded as having dreamt of a "philosophy without style," may consolidate the restoration of style's philosophical import.     

Personalidad,estrategias cognitivas y tiempo de Inspección

Resumen

En el presente trabajo se han empleado las medidas cronométricas de Tiempo de Inspección (TI) y Tiempo de Reacción (TR) para estudiar los efectos de las diferencias individuales en extroversion sobre una tarea de discriminación perceptual. Para ello se utilizaron dos grupos de sujetos que habían obtenido puntuaciones máximas y mínimas en la dimensión Extraversión del Test EPI de H. J. Eysenck. Se postuló que los extrovertidos obtendrían un TI más corto que los introvertidos y asimismo un TR también más corto, de acuerdo a los modelos de Brebner (1980) y Tous (1986). Los resultados indicaron que si bien existieron diferencias entre extrovertidos e introvertidos en cuanto a las medidas cronométricas, estas dit erencias dependieron del uso diferencial de estrategias de resolver la tarea que fueron utilizadas por estos sujetos.     

Cómo predecir a algunas personas en algunas ocasiones: la búsqueda de consistencias transituacionales en la conducta

RESUMEN

La controversia, históricamente repetida, sobre la existencia de consistencias transituacionales er la conducta se mantiene debido a la discrepancia entre nuestras intuiciones, que afirman su existencia, y la investigación, que la niega. Se argumenta que los supuestos nomotéticos del paradigma tradicional de investigación son incorrectos y que, adoptando algunos de los supuestos indiográficos empleados en nuestras intuiciones, se pueden obtener mayores coeficientes de correlación transituacionales. Sepresenta un estudio que muestra que es posible identificar a priori a los individuos que serán consistentes tran- situacionalmente y aquellos que no lo serán, y se concluye que la evaluación de la personalidad debe atender no sólo a las situaciones—como recientemente se ha insistido—sino también a las personas.     

STRONG MILITARY FAMILIES INTERVENTION ENHANCES PARENTING REFLECTIVITY AND REPRESENTATIONS IN FAMILIES WITH YOUNG CHILDREN

Military families face many challenges due to deployment and parental separation, and this can be especially difficult for families with young children. The Strong Military Families (SMF) intervention is for military families with young children, and consists of two versions: the Multifamily Group, and a Home‐based psychoeducational written materials program. The Multifamily Group was designed to enhance positive parenting through both educational components and in vivo feedback and support during separations and reunions between parents and children (n = 78 parents). In the present study, we examine parenting reflectivity and mental representations in mothers versus fathers in military families, service members versus civilian spouses/parenting partners, and before versus after participation in the SMF Multifamily Group and Home‐based interventions. Parenting reflectivity and mental representations were coded from the Working Model of the Child Interview (WMCI; C.H. Zeanah & D. Benoit, 1995). Results suggest that neither parenting reflectivity nor WMCI typology differs between mothers and fathers in military families, or between service members and civilian parenting partners. Furthermore, there was substantial stability in parenting reflectivity and WMCI typology from baseline to posttest, but participation in the Multifamily Group, relative to Home‐based, was associated with improvements in both parenting reflectivity and WMCI ratings from baseline to postintervention.     

DC:0–5: DIAGNOSTIC CLASSIFICATION OF MENTAL HEALTH AND DEVELOPMENTAL DISORDERS OF INFANCY AND EARLY CHILDHOOD

The significant growth in the clinical literature on early childhood psychopathologysince the publication of the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood: Zero to Three–Revised (DC:0–3R; ZERO TO THREE) in 2005 necessitated substantial revisions to the manual, which resulted in the publication of the DC:0–5: Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood: Zero to Five (ZERO TO THREE) in 2016. In addition to the decision to extend the early childhood diagnoses to include children through age 5 years, significant revisions were made to many diagnoses, and new diagnostic categories were added such as the Relationship Specific Disorder of Infancy/Early Childhood. Other additions, such as guidance for the development of a Cultural Formulation for the young child and his or her family and the inclusion of functional impairment criteria also contribute to making the DC: 0–5a substantially more comprehensive and robust diagnostic framework than its predecessor.
