Dear All,
We would like to invite you to the first event from the ELTE Cognitive
Seminar series for the new academic year:
*Bálint Forgács*
*Babies’ understanding of understanding: ERPs at the intersection of social
cognition & language comprehension*
Place: ELTE-PPK, Institute of Psychology, Izabella utca 46, room 405
Date and time: September 14th, 2016 (Wednesday), 10:30-12:00
Summary:
Infants already at 7 months of age seem to be tracking other people’s
beliefs, and under certain conditions, already at 9 months of age seem to
exhibit the N400 event related potential component, a neural marker of
semantic incongruity detection well known in adults. In our study we wanted
to investigate whether infants, similarly to adults, evaluate utterances
from the perspective of a potential communicative partner. In order to
investigate such social aspects of language processing, we presented
various toys to 14-month-old infants, named them in the presence of an
adult observer, and measured their electroencephalogram (EEG). On the basis
of previous studies, we chose fifteen toys for which the labels are
suspected to be known to infants, and named them by playing an audio file.
We measured the infants’ ERPs time-locked to the onset of the object’s
name. Half of the time the object was named congruently from the
perspective of the infant, but incongruently from the perspective of the
observer (who had a false belief about the identity of the object), and
half of the time it was named congruently from both of their perspectives.
Therefore, infants experienced a correct object label at all times, but the
observer had either a true or a false belief about the identity of the
object at the time of the object naming. Preliminary analysis of the ERPs
revealed that the label incongruent for the observer evoked a greater
negativity in the 300-500 ms time window over centro-parietal electrode
sites in infants compared to the label congruent for both parties (p <
.05). Further analyses and control experiments are under way, but the
present finding already suggests that infants use their language
comprehension system right from the onset to evaluate not only their own,
but also their communicative partner’s comprehension of utterances.
