Losing control in front of a fearful face: The effect of emotional information on cognitive control

How is our cognitive control system modulated by emotional information, especially fearful stimuli? An intuitive hypothesis is that fearful stimuli would enhance cognitive control so that people could switch from the ongoing task to emergent events more quickly to secure themselves. To test this hypothesis, we investigated the influence of emotional information on the shift function of cognitive control by using the task-cueing procedure, in which face images were presented as cues. With the gender of faces indicating which task to do, we manipulated the emotional valence of faces (neutral vs. fearful), finding that the switch costs were larger in the trials containing fearful cues than in the trials containing neutral cues (Experiment 1). This effect was not caused by enlarging task-set interference (Experiment 2), nor by slowing down cue encoding (Experiment 3). Contrary to the intuitive hypothesis, our results suggested that the endogenous task-set reconfiguration process was impaired when fearful faces were presented. We speculated that the benefit of decreasing cognitive flexibility in face of fearful stimuli is to speed up response in a dangerous environment, and this accelerating response is achieved by suppressing the goal-directed system to permit the fast, automatic stimulus-driven system to govern behaviours.     

Flexible and inflexible task sets: Asymmetric interference when switching between emotional expression,sex, and age classification of perceived faces

The present study investigated whether the processing characteristics of categorizing emotional facial expressions are different from those of categorizing facial age and sex information. Given that emotions change rapidly, it was hypothesized that processing facial expressions involves a more flexible task set that causes less between-task interference than the task sets involved in processing age or sex of a face. Participants switched between three tasks: categorizing a face as looking happy or angry (emotion task), young or old (age task), and male or female (sex task). Interference between tasks was measured by global interference and response interference. Both measures revealed patterns of asymmetric interference. Global between-task interference was reduced when a task was mixed with the emotion task. Response interference, as measured by congruency effects, was larger for the emotion task than for the nonemotional tasks. The results support the idea that processing emotional facial expression constitutes a more flexible task set that causes less interference (i.e., task-set “inertia”) than processing the age or sex of a face     

What remains of the intersubjective?: On the presencing of self and other

Recent work in the social sciences has been concerned with how we understand the subject. This has entailed critiquing the ways the subject has traditionally been understood – as a mental entity existing prior to and so organizing our experience of the world. In its place a relational subject has been posited, one emerging through a combination of affective experiences, performative enunciations, and haunting absent presences. However, the implications of such critiques for how we understand intersubjective relations have not been discussed. What remains of intersubjectivity when any subject entering into a relation has already been decentred amid a more-than human ecology of affective relations? In response, this paper draws on the work of Jean-Luc Nancy in developing understandings of the socio-spatial constitution of subjectivity/intersubjectivity in terms of movements of presencing. Here the body-subject is always in approach to itself and others, but neither is actually reached, never (self) present, always already receding: a spacing at the heart of any relation. The discussion is interspersed with a series of narrative sections outlining an encounter between a street performer and their audience which draw attention to a number of key themes in any understanding of intersubjectivity and attempt to expose this inherent dis-position.
