Toward an exploration of feeling of strangeness in schizophrenia: perspectives on acousmatic and everyday listening

The aim of this study was to investigate abnormal perceptual experiences in schizophrenia, in particular the feeling of strangeness, which is commonly found in patients' self-reports. The experimental design included auditory complex stimuli within 2 theoretical frameworks based on "sensory gating deficit" and "aberrant salience," inspired from conventional perceptual scales. A specific sound corpus was designed with environmental (meaningful) and abstract (meaningless) sounds. The authors compared sound evaluations on 3 perceptual dimensions (bizarre, familiar, and invasive) and 2 emotional dimensions (frightening and reassuring) between 20 patients with schizophrenia (SCZ) and 20 control participants (CTL). The perceptual judgment was rated on independent linear scales for each sound. In addition, the conditioning-testing P50 paradigm was conducted on 10 SCZ and 10 CTL. Both behavioral and electrophysiological data confirmed the authors' expectations according to the 2 previous theoretical frameworks and showed that abnormal perceptual experiences in SCZ consisted of perceiving meaningful sounds in a distorted manner and as flooding/inundating but also in perceiving meaningless sounds as things that become meaningful by assigning them some significance. In addition, the use of independent scales to each perceptual dimension highlighted an unexpected ambivalence on familiarity and bizarreness in SCZ compatible with the explanation of semantic process impairment. The authors further suggested that this ambivalence might be due to a conflicting coactivation of 2 types of listening, that is, every day and musical (or acousmatic) listening.     

Perception of relative depth interval: systematic biases in perceived depth

Given an estimate of the binocular disparity between a pair of points and an estimate of the viewing distance, or knowledge of eye position, it should be possible to obtain an estimate of their depth separation. Here we show that, when points are arranged in different vertical geometric configurations across two intervals, many observers find this task difficult. Those who can do the task tend to perceive the depth interval in one configuration as very different from depth in the other configuration. We explore two plausible explanations for this effect. The first is the tilt of the empirical vertical horopter: Points perceived along an apparently vertical line correspond to a physical line of points tilted backwards in space. Second, the eyes can rotate in response to a particular stimulus. Without compensation for this rotation, biases in depth perception would result. We measured cyclovergence indirectly, using a standard psychophysical task, while observers viewed our depth configuration. Biases predicted from error due either to cyclovergence or to the tilted vertical horopter were not consistent with the depth configuration results. Our data suggest that, even for the simplest scenes, we do not have ready access to metric depth from binocular disparity.     

Toward an Improved Understanding of Work Motivation Profiles

The present research proposes an improved understanding of work motivation by identifying employees’ motivational profiles while taking into account the dual global and specific nature of work motivation proposed by self-determination theory (SDT). To document the construct validity of these latent profiles, we relied on the circumplex model of employees’ well-being to investigate whether they differed in terms of burnout, work satisfaction, and work addiction. Results from analyses conducted among a sample of 955 employees revealed five distinct profiles characterized by differing levels of global and specific forms of motivation: Intrinsically Motivated, Poorly Motivated, Driven, Conflicted, and Self-Determined. Lower levels of burnout and work satisfaction were associated with profiles characterized by higher global levels of self-determination and more autonomous forms of motivation, matching theoretical expectations. Interestingly, work addiction was highest in the Driven profile and lowest in the Self-Determined profile, suggesting that autonomous forms of motivation are not always able to buffer the adverse effects of controlled forms of motivation. Our results also suggest that the specific qualities of work motivations are just as important as the global levels of self-determination in the identification of work motivation profiles.     

Psychoanalysis and evaluation: a stratified model focused on the uniqueness of the case

ABSTRACT

Objectives: This article addresses the methodological controversies surrounding the issue of how to evaluate the psychotherapies. It proposes to identify the principles of an integrative and stratified model in order to report the results of analytical therapy (its efficacy) based on the very effectiveness of its processes. Thus, the uniqueness of the case is put at the center of the evaluation setting.

Methods: Drawing on science studies, the authors engage in a reflexive exercise on the problem of psychoanalysis’ evaluation based on methodological questions raised in the field over time and current issues related to practice.

Results: First, the regularly asserted opposition between the norms of analytical practice and those governing standard evaluation procedures is reinterpreted as the effect of a lack of intermediate epistemic patterns.

Second, the fundamental principles of an integrative model are considered so as to translate and articulate a set of heterogeneous requirements into distinct strata.

Discussion: Since psychoanalysis is fundamentally a case-by-case practice characterized by inequivalence and unexpectedness, its utmost aim is to use a type of effectiveness based on the singularity of the case. However, this does not prevent it from being evaluable provided that the epistemic levels of the evaluation are clearly differentiated.
