dc.description.abstract | Results illustrating an atypical neural processing in the early and late differentiation of infant faces have been obtained with
neglectful mothers. The present study explores whether a different pattern of response is observed when using non-infant
affective pictures. We examined the event-related evoked potentials and induced delta, theta and alpha activity in 14
neglectful mothers and 14 control mothers elicited while categorizing positive, negative and neutral pictures from the
International Affective Picture System. Self-reports of anhedonia and empathy were also recorded. Early posterior negativity,
P200 and late positive potential components were modulated by the emotional content of pictures in both groups.
However, the LPP waveform had a more delayed and more attenuated maximum in neglectful mothers than in control
mothers. Oscillatory responses indicated lower power increases for neglectful mothers than for control mothers in delta (1–
4 Hz), theta (4–8 Hz) and lower alpha (8–10 Hz) bands at frontal sites, and a more consistent increase for neglectful mothers
in theta and lower alpha bands at occipital sites, especially for negative pictures. These findings help us to better
understand the limits of emotional insensitivity in neglectful mothers. | en |
