Characterization of controlled gamblers and pathological gamblers using the social representation theory

Introduction

In industrialized countries, gambling disorder tends to become a major issue. The use of the social representation theory provides clues for a better understanding of pathological gamblers.

Structure sociale et cultures organisationnelles : une application du modèle des représentations sociales

The theme of organizational culture has been subject of many studies, which postulates are divergent. Consensual, shared and transmitted by the direction for some persons, they follow from the articulation of professional identities models for other persons. Social representation theory can allow us to understand that co-existence of consensual and specific elements, depending on the social structure of the organization. A questionnaire, developed after 24 semi-directive interviews, has been submitted to 95 employees of a large distribution company. Results show that organizational culture is a representation organized on six themes, socially elaborated on the interaction of groups situated in different positions. Consensual elements pass through the various groups, and some elements, more specifics, show the differences between these groups, depending on their strategic links.     

Muscular Imaginings—A Phenomenological and Enactive Model for Imagination*

A phenomenological model (labeled ‘EC’) is developed as an alternative to current analyses of the imagination in sport philosophy, heirs to an Enlightenment notion that conceptualizes imaginings as abstract, eidetic, and representational. EC describes how Eidetic and Corporeal Imaginings (EIs & CIs) phenomenologically structure our imaginative undertakings. EIs keep the ‘ideal’ aspect, but CIs—enacted, corporeal, non-representational—are more fundamental and foundational. Sports are particularly suited to express CIs’ muscular imaginings, which result in novel performances. An enactive framework theorizes CIs as non-representational interactions.     

知觉表征精度对工作记忆中抑制干扰能力的影响

工作记忆的容量十分有限,需要选择性地抑制与目标无关信息的干扰,工作记忆容量高的个体,其抑制干扰的能力也更强。本研究采用带有不同形状干扰刺激的色块颜色回忆任务考察干扰对工作记忆容量和表征精度的影响,结果发现,当负荷超出工作记忆容量范围时,干扰减少了记忆所能表征客体的个数;当负荷在工作记忆容量范围内时,干扰降低了记忆中表征客体的精度。更进一步,研究采用独立的知觉任务来测量知觉表征的精度,并探讨作为信息加工的初始阶段的知觉表征如何影响工作记忆加工过程中抑制干扰的能力。将实验中收集的48名有效被试按照知觉表征精度的高低平均分为两组,结果发现上述干扰效应主要表现在知觉表征精度较低的组中,并且该组中知觉表征精度越高的个体,其工作记忆抑制干扰的能力也越强。本研究为实践中通过知觉训练来提升工作记忆的抑制干扰能力提供了理论指导。     

EPIGENETICS,REPRESENTATION, AND SOCIETY

In recent decades, advances in the life sciences have created an unprecedentedly detailed picture of heredity and the formation of the phenotype where clusters of simplistic reductionist and deterministic views and interpretations have begun to lose ground to more complex and holistic notions. The developments in gene regulation and epigenetics have become a vivid emblem of the ongoing ‘softening’ of heredity. Despite this headway, the outlook and rhetoric widely popular in the twentieth century favoring the ‘gene’ in the ‘gene?genetic plasticity?phenotype?environment’ tetrad have not been successfully tackled but continue to exist in parallel with a new, equally monochromatic, viewpoint championing genetic plasticity. An examination of epigenetics and its presentation in the public sphere, open to a conversation with the social disciplines and philosophy, could address this dichotomy and contribute to the discourse. This article outlines key biological aspects of epigenetics and discusses the language, presentation and wider resonance of this field of life science research.     

Dealing with Big Numbers: Representation and Understanding of Magnitudes Outside of Human Experience

Being able to estimate quantity is important in everyday life and for success in the STEM disciplines. However, people have difficulty reasoning about magnitudes outside of human perception (e.g., nanoseconds, geologic time). This study examines patterns of estimation errors across temporal and spatial magnitudes at large scales. We evaluated the effectiveness of hierarchical alignment in improving estimations, and transfer across dimensions. The activity was successful in increasing accuracy for temporal and spatial magnitudes, and learning transferred to the estimation of numeric magnitudes associated with events and objects. However, there were also a number of informative differences in performance on temporal, spatial, and numeric magnitude measures, suggesting that participants possess different categorical information for these scales. Educational implications are discussed.     

盲人建构陌生环境空间表征的策略及其作用

空间表征对于盲人定向行走具有重要意义。以往研究者集中探讨早期视觉经验缺失对于盲人空间表征的影响, 较少探究空间表征建构的过程性因素, 即探路策略对于盲人空间表征的影响。本研究采用现场实验的方法探究了盲人建构陌生环境空间表征采用的策略及其作用。结果发现：视觉经验缺失对盲人陌生环境空间表征能力造成了不利影响, 然而, 被试运用有效的策略可以弥补视觉缺失带来的损失, 且利用空间关系策略的个体所建构的空间表征更为精确, 定向行走效率也更高。     

情绪概念加工与情绪面孔知觉的相互影响

通过3个实验探讨情绪概念加工与情绪面孔知觉是否存在相互影响, 以及加工深度对两者关系的影响。实验1采用情绪面孔启动范式, 探讨较深的情绪概念加工层面对情绪概念与情绪面孔的关系的影响。实验2更改概念任务, 探讨较浅的概念加工层面对两者关系的影响。实验3缩短启动面孔呈现时间, 探讨较浅的面孔知觉层面对两者关系的影响。通过研究主要得出以下结论：(1)情绪概念加工与情绪面孔知觉确实存在相互影响; (2)概念加工深度影响两者关系的方向性, 在较深的概念加工层面, 两者的关系是双向的, 在较浅的概念加工层面, 两者的关系是单向的; (3)知觉加工深度也影响两者关系的方向性, 在较深的知觉加工层面, 两者的关系是双向的, 在较浅的知觉加工层面, 没有发现两者的相互影响。本研究为抽象概念的具身表征提供了实证支持。     

中文词汇加工中的饱和现象

长时间注视一个字或词语后,感觉这个字词变得奇怪且陌生,这种现象称为饱和现象。本研究采用快速类别/词汇匹配范式,考察中文词汇加工中的饱和现象。实验1-3发现单纯的语义或字形的重复均未能引发饱和,只有类别标签在字形和语义上的同时重复才引发饱和,表明与英文饱和相似,中文饱和发生在字形加工和语义加工的联结阶段。实验4结果表明,中文饱和还能够由表义部件的重复引发,体现了中文饱和的特殊性。     

Psychoanalytic application and psychoanalytic integrity

In this article, the author offers an analysis of psychoanalytic application, defined as the breaking of new conceptual ground in some field of knowledge whereby the new idea is conceived, and later articulated, with the aid of reference to analogous phenomena in psychoanalysis. It requires apt analogy based on competent understanding of the applied field and of psychoanalysis. Only when the relevant differences between the applied and psychoanalytic fields are grasped can the extent of certain parallels emerge. The thinking by analogy that comprises psychoanalytic application may be intuitive and implicit, but should be susceptible of explicit theoretical elaboration that specifies, precisely, the point(s) of correspondence between psychoanalysis and the applied field in relation to a precise specification of their relevant differences. Applied psychotherapy at the interface of the internal and external worlds (historically rooted in casework) is employed as a model. By analogy with Donnet's concept of the analytic site, the author proposes the concept of the psychodynamic (case)work site, and elaborates it for that applied field in order to elucidate the proposed principles of psychoanalytic application.
