AbstractEarly neglect or maltreatment has been associated with changes in children's processing of emotional facial expressions, including a hypersensitivity to the emotion of anger. This may facilitate the avoidance of danger in a maltreating environment. However, few studies have examined whether experiences of early life stress (ELS) are associated with atypical avoidance responses towards emotional facial expressions, or whether the effects of ELS can be observed in adult participants. The present study therefore examined the effects of ELS on adults’ approach-avoidance tendencies towards angry, happy, and neutral facial expressions. Surprisingly, higher levels of ELS were associated with reduced avoidance of angry facial expressions among individuals with no evidence of mental illness. In contrast, there was no evidence of a relationship between ELS and avoidance of angry facial expressions among individuals with experience of mental illness. These novel findings suggest that ELS-related changes in social cognition can be observed years after the ELS itself occurred.

Neutral Expression

A growing body of evidence shows that the prolonged execution of approach movements towards stimuli and avoidance movements away from them affects their evaluation. However, there has been no systematic investigation of such training effects. Therefore, the present study compared approach-avoidance training effects on various valenced representations of one neutral (Experiment 1, N = 85), angry (Experiment 2, N = 87), or smiling facial expressions (Experiment 3, N = 89). The face stimuli were shown on a computer screen, and by means of a joystick, participants pulled half of the faces closer (positive approach movement), and pushed the other half away (negative avoidance movement). Only implicit evaluations of neutral-expression were affected by the training procedure. The boundary conditions of such approach-avoidance training effects are discussed.

Repetition Priming Effect

Behavioral studies have shown that two different morphed faces perceived as reflecting the same emotional expression are harder to discriminate than two faces considered as two different ones. This advantage of between-categorical differences compared with within-categorical ones is classically referred as the categorical perception effect. The temporal course of this effect on fear and happiness facial expressions has been explored through event-related potentials (ERPs). Three kinds of pairs were presented in a delayed same–different matching task: (1) two different morphed faces perceived as the same emotional expression (within-categorical differences), (2) two other ones reflecting two different emotions (between-categorical differences), and (3) two identical morphed faces (same faces for methodological purpose). Following the second face onset in the pair, the amplitude of the bilateral occipito-temporal negativities (N170) and of the vertex positive potential (P150 or VPP) was reduced for within and same pairs relative to between pairs. This suggests a repetition priming effect. We also observed a modulation of the P3b wave, as the amplitude of the responses for the between pairs was higher than for the within and same pairs. These results indicate that the categorical perception of human facial emotional expressions has a perceptual origin in the bilateral occipito-temporal regions, while typical prior studies found emotion-modulated ERP components considerably later.
