The aim of the study was to investigate parental perception and interpretation of infant emotional expression depending on their attachment representation. Forty-six parents' responses to infant pictures depicting positive, neutral, and negative emotions were assessed on the level of affective judgments (valence, arousal), mimic responses (facial muscle activity), and of the eyelid reflex (using the startle paradigm). Results revealed small differences between parents of different attachment representations with respect to their subjective evaluations. However, secure parents, as compared to insecure ones, showed a positive bias in their mimic responses to infant pictures. The modulation of the startle response indicated a negative evaluation of negative infant emotion expressions in dismissing parents, while an augmentation of the startle response to negative infant emotions could not be observed in secure and preoccupied parents. The findings highlight the role of attachment experiences for emotional information processing in parents and its consequences for parental behavior.

To study parental experience and perception of infant emotional expressions parents' responses to infant pictures depicting positive, neutral and negative emotions were assessed on the level of affective judgments (perceived and experienced valence and arousal), of mimic responses (facial muscle activity) and of the eyelid reflex (using the startle paradigm). In general, while parents were able to appropriately perceive infant emotions and were clearly affected by them, they exhibited a bias for positive interpretation. This was obvious from their subjective evaluations which, e.g. were more positive for experienced than for perceived valence, as well as from their mimic responses indicating positive responses in general. In addition, infant pictures including the negative ones lead to an inhibition of the startle reflex, indicating a positive evaluation of infant emotions on the sub-cortical level. These effects were most prominent when parents were faced with pictures of their own infants as compared to unfamiliar ones. The way parents process information about infant emotions may facilitate appropriate responsiveness to infants' needs.

Thus, infant emotional expression as well as the caregivers' responses are substantial components of infantcaregiver relationship. Because infants are not capable of autonomous
