Emotions outside the box��the new phenomenology of feeling and corporeality

The following text is the first ever translation into English of a writing by German phenomenologist Hermann Schmitz (*1928). In it, Schmitz outlines and defends a non-mentalistic view of emotions as phenomena in interpersonal space in conjunction with a theory of the felt body’s constitutive involvement in human experience. In the first part of the text, Schmitz gives an overview covering some central pieces of his theory as developed, for the most part, in his massive System of Philosophy, published in German in a series of volumes between 1964 and 1980. Schmitz’s System is centred on the claim that the contemporary view of the human subject is the result of a consequential historical process: A reductionist and ‘introjectionist’ objectification of lived experience culminating in the ‘invention’ of the mind (or ‘soul’) as a private, inner realm of subjective experience and in a corresponding ‘grinding down’ of the world of lived experienced to a meagre, value-neutral ‘objective reality’. To counter this intellectualist trend, Schmitz puts to use his approach to phenomenology with the aim of regaining a sensibility for the nuanced realities of lived experience—hoping to make up for what was lost during the development of Western intellectual culture. Since both this text and the overall style of Schmitz’s philosophising are in several ways unusual for a contemporary readership, a brief introduction is provided by philosophers Jan Slaby and Rudolf Owen Müllan, the latter of whom translated Schmitz’s text into English. The introduction emphasises aspects of Schmitz’s philosophy that are likely to be of relevance to contemporary scholars of phenomenological philosophy and to its potential applications in science and society.     

Effects of stimulus synchrony on mechanisms of perceptual organization

When neurons adopt a synchronized, oscillatory response to stimulus Gestalten, the phase of those oscillations almost always varies relative to stimulus activity. This has been taken to indicate that form-coding mechanisms are synchronized by internal timing mechanisms, and/or may be sensitive to stimulus activity only via motion detectors. This proposal is problematic for interpreting recent demonstrations of the effects of stimulus synchrony particularly when stimuli are stationary. Here we offer an account of stimulus-driven synchronization supported by evidence that segmentation by stimulus synchrony can be relatively insensitive to explicit motion signals. The argument is made that qualitative similarities between the effects of phase-independent and phase-locked oscillations in the EEG, the effects of phase synchronization at the cellular level and evidence for phase-enhanced stimulus grouping should be considered as functionally equivalent. This argument emphasizes the flexibility of temporal synchrony as a code for perceptual organization.     

On the relation between spontaneous perspective taking and other visuospatial processes

Common processes and representations engaged by visuospatial tasks were investigated by looking at four frequently used visuospatial research paradigms, the aim being to contribute to a better understanding of which specific processes are addressed in the different paradigms compared. In particular, the relation between spontaneous and instructed perspective taking, as well as mental rotation of body-part/non-body-part objects, was investigated. To this end, participants watched animations that have been shown to lead to spontaneous perspective taking. While they were watching these animations, participants were asked to explicitly adopt another perspective (Experiment 1), perform a mental object rotation task that involved a non-body-part object (Experiment 2), or perform a mental rotation of a body-part object (Experiment 3). Patterns of interference between the tasks, reflected in the reaction time patterns, showed that spontaneous and instructed perspective taking rely on similar representational elements to encode orientation. By contrast, no such overlap was found between spontaneous perspective taking and the rotation of non-body-part objects. Also, no overlap in orientation representation was evident with mental body-part rotations. Instead of an overlap in orientation representations, the results suggest that spontaneous perspective taking and the mental rotation of body parts rely on similar—presumably, motor—processes. These findings support the view that motor processes are involved in perspective taking and mental rotation of body parts.     

Occupational factors and 5-year weight change among men in a danish national cohort.

This study explored whether factors related to the work environment could predict changes in body mass index (BMI) and whether the effect of psychosocial factors was dependent on baseline BMI. The sample consisted of 1,980 male employees from the Danish National Work Environment Cohort Study. Changes in BMI between 1995 and 2000 were analyzed, by multiple regression, as a function of background variables and a series of occupational variables obtained in 1995. Age, baseline BMI, job insecurity, and psychological demands predicted changes in BMI. Job insecurity and high or low psychological demands increased the likelihood of weight gain among obese employees, whereas they increased the likelihood of weight loss among employees with a low BMI.

Heartbeat perception in social anxiety before and during speech anticipation

According to current cognitive models of social phobia, individuals with social anxiety create a distorted image of themselves in social situations, relying, at least partially, on interoceptive cues. We investigated differences in heartbeat perception as a proxy of interoception in 48 individuals high and low in social anxiety at baseline and while anticipating a public speech. Results revealed lower error scores for high fearful participants both at baseline and during speech anticipation. Speech anticipation improved heartbeat perception in both groups only marginally. Eight of nine accurate perceivers as determined using a criterion of maximum difference between actual and counted beats were high socially anxious. Higher interoceptive accuracy might increase the risk of misinterpreting physical symptoms as visible signs of anxiety which then trigger negative evaluation by others. Treatment should take into account that in socially anxious individuals perceived physical arousal is likely to be accurate rather than false alarm.
