Title: How other people affect our attention, emotion, and motivation.
Speaker:Jari Hietanen (University of Tampere and University of Tokyo)
In my talk I will describe results from three different lines of our
recent research. First, I will present studies investigating gaze-cued
attention orienting. An interesting question on the field has been whether
gaze-cued shifts of attention are qualitatively different from shifts of
attention triggered, for example, by symbolic cues like arrows. Gaze-cued
attention orienting has been suggested to be more strongly automatic and
reflexive than orienting to arrows. However, our recent results question
these suggestions. When the automaticity hypothesis is put into a rigorous
test, gaze cuing does not seem to be any more automatic than arrow cuing.
Also, there are instances, when other people's laterally averted gaze can,
in fact, trigger attention shifts away from this direction. In the second
part of my talk, I will describe studies suggesting that seeing another
person's direct vs. averted gaze has differential effects on perceivers'
affective-motivational responses as measured by frontal EEG asymmetry and
autonomic responses. The results show that direct gaze seem to elicit brain
activation associated with motivational approach tendency, whereas averted
gaze elicits activation associated with avoidance. Autonomic responses also
discriminate between direct and averted gaze, being larger to direct than
averted gaze. Interestingly, our results show that, in these studies, the
gaze direction effects are observed only when the participants are looking
at a "live" face of another person, but not when the same face is presented
as a picture on a computer monitor. Finally, I will describe results from
our newest line of research. This relates to visual processing of human
bodies. Previous event-related potential studies have shown that the
well-know 'face sensitive' N170 component is also sensitive to perception of
human bodies. We have investigated whether the visual processing of bodies
as reflected by N170 response is sensitive to the degree of clothing. Our
results show that the early visual processing of male and female human
bodies is enhanced if their sex-related features are visible. We propose
that this enhancement of visual processing of nude over clothed bodies
reflects the relevance of nude bodies to sexually motivated behavior.
