The role of variability in the property listing task

It is generally believed that concepts can be characterized by their properties (or features). When investigating concepts encoded in language, researchers often ask subjects to produce lists of properties that describe them (i.e., the Property Listing Task, PLT). These lists are accumulated to produce Conceptual Property Norms (CPNs). CPNs contain frequency distributions of properties for individual concepts. It is widely believed that these distributions represent the underlying semantic structure of those concepts. Here, instead of focusing on the underlying semantic structure, we aim at characterizing the PLT. An often disregarded aspect of the PLT is that individuals show intersubject variability (i.e., they produce only partially overlapping lists). In our study we use a mathematical analysis of this intersubject variability to guide our inquiry. To this end, we resort to a set of publicly available norms that contain information about the specific properties that were informed at the individual subject level. Our results suggest that when an individual is performing the PLT, he or she generates a list of properties that is a mixture of general and distinctive properties, such that there is a non-linear tendency to produce more general than distinctive properties. Furthermore, the low generality properties are precisely those that tend not to be repeated across lists, accounting in this manner for part of the intersubject variability. In consequence, any manipulation that may affect the mixture of general and distinctive properties in lists is bound to change intersubject variability. We discuss why these results are important for researchers using the PLT.     

Why the Hardest Logic Puzzle Ever Cannot Be Solved in Less than Three Questions

Rabern and Rabern (Analysis 68:105–112 2) and Uzquiano (Analysis 70:39–44 4) have each presented increasingly harder versions of ‘the hardest logic puzzle ever’ (Boolos The Harvard Review of Philosophy 6:62–65 1), and each has provided a two-question solution to his predecessor’s puzzle. But Uzquiano’s puzzle is different from the original and different from Rabern and Rabern’s in at least one important respect: it cannot be solved in less than three questions. In this paper we solve Uzquiano’s puzzle in three questions and show why there is no solution in two. Finally, to cement a tradition, we introduce a puzzle of our own.     

Mindful awareness of feelings increases neural performance monitoring

Mindfulness has been associated with enhanced performance monitoring; however, little is known about the processes driving this apparent neurocognitive benefit. Here, we tested whether focusing present-moment awareness toward the nonjudgmental experience of emotion facilitates rapid neural responses to negative performance outcomes (i.e., mistakes). In particular, we compared whether directing present-moment awareness toward emotions or thoughts would enhance the neurophysiological correlates of performance monitoring: the error-related negativity (ERN) and the error positivity (Pe). Participants were randomly assigned to either a thought-focused or an emotion-focused group, and first they completed a preinduction go/no-go task. Subsequently, the groups followed inductions that promoted mindful attention toward either thoughts or emotions, before completing a final postinduction go/no-go session. The results indicated that emotion-focused participants demonstrated higher neural sensitivity to errors in the time course of the ERN, whereas focusing on thoughts had no effect on performance monitoring. In contrast, neither induction procedure altered the amplitude of the later Pe component. Although our manipulations also induced changes in behavior, the ERN effects remained significant after controlling for performance. Thus, our results suggest that mindfulness meditation boosts early neural performance monitoring (ERN amplitude), specifically through meditation’s influence on affective processing.     

The Tower of London Test: different scoring criteria for diagnosing Alzheimer's disease and mild cognitive impairment

The Tower of London (TOL) is used for evaluating planning skills, which is a component of the executive functions. Different versions and scoring criteria were developed for this task, and some of them present with different psychometrical properties. This study aimed to evaluate two specific scoring methods of the TOL in diagnosing Mild Cognitive Impairment and probable Alzheimer's disease. The TOL total scores from 60 patients of each diagnosis were compared with the performance of 60 healthy-aged controls using receiver operating characteristics analysis and multinomial logistic regression. Krikorian method better diagnosed Alzheimer's disease, while Portellas's was better at discriminating healthy controls from Mild Cognitive Impairment, but were not efficient at comparing this last group with Alzheimer's patients. Regression analysis indicates that in addition to screening tests, TOL improves the classification of the three groups. The results suggest the two scoring methods used for this task may be useful for different diagnostic purposes.     

Trauma,perversion and marital bond

Abstract

The purpose of this article is to study in the clinic the incidence of so-called perverse phenomena in relationships, in order to find out when these phenomena depend on a perverse organization and when they are only a kind of erotic game between the couple, in both hetero- and homosexual aspects. The first difficulty was to find a definition of “perversion” shared by the authors who have carried out research on the subject and consequently to determine what characterizes a perverse marital bond. In contrast to neurosis, which can be defined by the use of the repression mechanism, the mechanism of disavowal is not exclusive for perversion since it can be found even in other psychical arrangements. Is it, then, a structure or a psychological organization? It is also considered to be a “truth” in psychoanalysis that the pervert cannot be analyzed. But is it the pervert who cannot be analyzed, or is it the analyst who cannot bear listening to him? Do the theoretical references of the analyst not give sufficient theoretical support to maintain his listening? This paper presents the hypothesis that perversion is an attempt – always a frustrated one, and for this reason indefinitely repeated – to elaborate a trauma in which the pervert, identified with the traumatic agent, touches a point equally traumatic for his partner, turning the partner into an object of enjoyment. This arrangement allows the pervert, at least in his imagination, to leave the suffered trauma behind, adopting towards the object a position of activity and domination. Identifying with the aggressor, he leaves his partner paralyzed in the traumatic point, a situation that he knows all too well.

dos Reis Filho JT, et al Trauma, Perversion und eheliche Bande

Der Artikel untersucht klinische Fällen von sogenannter Perversion in Beziehungen, mit dem Ziel herauszufinden, wann es sich um eine perverse Organisation und wann es sich lediglich um eine spezielle Art von erotischem Spiel zwischen dem Paar handelt, dies sowohl in hetero- wie in homosexuellen Beziehungen. Die erste Schwierigkeit war, eine für alle Autoren akzeptable Definition von Perversion zu finden. Alle hatten Erfahrung in Forschung in diesem Gebiet und mussten sich auf Vorstellungen einigen, wodurch eine perverse eheliche Beziehung gekennzeichnet ist. Im Gegensatz zur Neurose, gekennzeichnet ausschliesslich von Verdrängungsmechanismen, kommt Ablehnung nicht ausschliesslich bei der Perversion vor sondern auch bei anderen psychischen Strukturen. Ist Perversion demnach eine psychische Struktur oder eine psychologische Organisation? Es wird auch als erwiesen betrachtet, dass ein Perverser nicht analysiert werden kann. Aber, ist es wirklich der Perverse, der nicht analysiert werden kann? Ist es nicht vielleicht der Analytiker, der es nicht ertragen kann, dem Perversen zuzuhören? Gibt der theoretische analytische Hintergrund des Analytikers ihm möglicherweise nicht genug Unterstützung, um das Zuhören aufrechterhalten zu können? Dieser Aufsatz vertritt die Hypothese, dass die Perversion ein unaufhörlich wiederholter, immer misslingender Versuch ist, ein Trauma aufzuarbeiten. Der Perverse ist identifiziert mit dem Täter im damaligen Trauma. Er trifft einen traumatisierten Punkt beim Partner und macht aus ihm ein Objekt seiner Lusterfüllung. Dieses Arrangement erlaubt dem Perversen-wenigstens in seiner Phantasie – das von ihm erlittene Trauma hinter sich zu lassen, indem er gegenüber dem Objekt eine Position der Aktivität und Dominanz einnimmt. Identifiziert mit dem Aggressor belässt er seinen Partner gelähmt am traumatischen Punkt-eine Situation, die er nur allzu gut an sich selbst kennt.

dos Reis Filho JT et al. Trauma, perversión y el vínculo marital

El propósito del presente trabajo es estudiar en la clínica la incidencia de los cada vez más llamados fenómenos perversos en las relaciones, para descubrir cuando este fenómeno depende de una organización perversa y cuando se trata de un tipo de juego erótico en las parejas, tanto en sus aspectos homosexuales como heterosexuales. La primera dificultad fue encontrar una definición de perversión compartida por los autores estudiosos de este tema y consecuentemente determinar las características de un vínculo marital perverso. En contraste con la neurosis que puede ser definida por el uso del mecanismo de la represión, el mecanismo de la negación no es característico de la perversión únicamente sino que se puede también encontrar en otras organizaciones psíquicas. ¿Se trata entonces de una estructura o de una organización psicológica? Se considera también que en psicoanálisis, es cierto que se trata al perverso como inanalizable. Bueno, ¿es el perverso el que no es analizable o es el psicoanalista que no puede soportar escucharlo? Acaso las referencias teóricas del analista no ofrecen suficientes soportes teóricos para mantener la escucha? Este trabajo presenta la hipótesis de que la perversión es un intento – siempre frustrado, y por lo mismo indefinidamente repetido- para elaborar un trauma en el que el perverso está identificado con el agente traumático, tocando un punto igualmente traumático en su pareja, convirtiendo a su pareja en objeto de su disfrute. Este arreglo permite al perverso, al menos en su imaginación, dejar atrás el trauma sufrido, adoptando con su objeto una posición de actividad y dominación. Identificándose con el agresor, deja a su pareja paralizada en el punto traumático, situación que el perverso sabe muy bien.     

Count data in psychological applied research

As some authors have noticed in fields other than psychology, level of measurement and distributional characteristics of count data are commonly not taken into account, so that they are analysed as normally distributed continuous variables, and therefore some general linear model is applied. In this work, we review a random sample of 457 articles published in the last four years in journals with the highest impact factor in the Journal Citation Reports (JCR Social Sciences Edition) of the Institute for Scientific Information. The goals are to know how often count variables appear in psychological applied research and which data analyses are used when dealing with count response variables. Examination showed that there is a notable presence of count variables, especially in some topics in psychology and a remarkable misapplication of the general linear model. One deals with causes and consequences of this approach to data analysis and suggests the use of specific models to analyse count data.     

Remapping versus short-term memory in visual stability across saccades

Saccadic eye movements cause displacements of the image of the visual world projected on the retina. Despite the ubiquitous nature of saccades, subjective experience of the world is continuous and stable. In five experiments, we addressed the mechanisms that may support visual stability: matching of pre- and postsaccadic locations of the target by an internal copy of the saccade, or retention of the visual attributes of the target in short-term memory across the saccade. Healthy human adults were instructed to make a saccade to a peripheral Gabor patch. While the saccade was in midflight, the patch could change location, orientation, or both. The change occurred either immediately or following a 250-ms blank during which no visual stimuli were available. In separate experiments, subjects had to report either whether the patch stepped to the left or right or whether the orientation rotated clockwise or counterclockwise. Consistent with previous findings, we found that transsaccadic displacement discrimination was enhanced by the addition of the blank. However, contrary to previous findings reported in the literature, the feature change did not improve performance. Transsaccadic orientation change discrimination did not depend on either an irrelevant temporal blank or a simultaneous irrelevant target displacement. Taken together, these findings suggest that orientation is not a relevant visual feature for transsaccadic correspondence.     

Homophobia or sexism? A systematic review of prejudice against nonheterosexual orientation in Brazil

Since it was coined in the 1970s, in the United States, the term “homophobia” has been invoked to define the prejudice against nonheterosexual orientation. Besides the US, the phenomenon has been detected in many contemporary societies, including Brazil. Prejudice against nonheterosexual orientation is strongly associated with the historical and social contexts in which it is embedded, which means that the term should not be used without a clear definition of its local specificities. This applies to the recent debate around homophobia in the Brazilian context. In an attempt to identify existing studies of prejudice against nonheterosexual orientations in Brazil, a systematic review was conducted in SciELO indexes, PubMed, PsycINFO, SCOPUS, and Web of Science. The articles were collected using the keyword “homophobia” and related terms, and “Brazil”, in the languages ??of the databases. The search returned 355 articles. Of these, 247 were removed because they were duplicates. The abstracts of 109 studies published between 1973 and 2011were analyzed. Thirty‐one articles were identified as relevant. The reviewed studies indicate that prejudice against nonheterosexual orientations is an evident and widespread phenomenon that is prevalent in various populations and contexts. Nevertheless, prejudice in Brazil is not homogeneous, and particular attention is necessary to the inequality of gender relations (sexism) and prejudice against gender nonconformity, which seem to explain, if not cause, most of the prejudice against nonheterosexual orientations. Although theoretically there is a clear distinction between sexual orientation and gender expression, from the standpoint of manifestation of prejudice that distinction seems to be more tenuous.
