Measuring affective reactivity in individuals with autism spectrum personality traits using the visual mismatch negativity event-related brain potential.

Gayle LC, Gal DE, Kieffaber PD - Front Hum Neurosci (2012)

Bottom Line: Consistent with prior research, it was anticipated that the amplitude of the vMMN would be increased for emotionally salient stimuli.Higher AQ scores were associated with smaller amplitudes of the vMMN in response to happy, but not sad emotional deviants.This research suggests that the vMMN elicited by deviant emotional expressions may be a useful indicator of affective reactivity and may thus be related to social competency in Autism Spectrum Disorder (ASD).

ABSTRACT
The primary aim of this research was to determine how modulation of the visual mismatch negativity (vMMN) by emotionally laden faces is related to autism spectrum personality traits. Emotionally neutral faces served as the standard stimuli and happy and sad expressions served as vMMN-eliciting deviants. Consistent with prior research, it was anticipated that the amplitude of the vMMN would be increased for emotionally salient stimuli. Extending this finding, it was expected that this emotion-based amplitude sensitivity of the vMMN would be decreased in individuals with higher levels of autism spectrum personality traits as measured by the Adult Autism Spectrum Quotient (AQ). Higher AQ scores were associated with smaller amplitudes of the vMMN in response to happy, but not sad emotional deviants. The fact that higher AQ scores were associated with less sensitivity only to happy emotional expressions is interpreted to be consistent with the negative experience of social interactions reported by individuals who are high on the autism spectrum. This research suggests that the vMMN elicited by deviant emotional expressions may be a useful indicator of affective reactivity and may thus be related to social competency in Autism Spectrum Disorder (ASD).

Figure 4: Mean vMMN (deviant minus standard) amplitudes at each level of Hemisphere, Region, and Deviant Type.

Mentions: These main effects were qualified by a number of interactions, including the 3-way interaction between Hemisphere, Region, and Emotion, F(2, 72) = 3.3, p < 0.05. Figure 4, depicting the mean vMMN amplitudes for each Emotion, Hemisphere, and Region, facilitates the interpretation of this interaction. Inspection of Figure 4 reveals that lateralization of the vMMN to the right hemisphere was increased for sad and happy by comparison with control conditions and that this effect was largest at lateral electrode positions (e.g., PO8).
