Social attention Flashcards
Eye trackers
Eye trackers can be used to see what captures our attention and how it does
Looks at pupil dilation
Gives us insight into underlying cognitive processes
Social attention
Attending to social information in our environment
We are predisposed to look to social info in our environment
Detection of biological motion is an intrinsic capacity of the visual system which is part of the mechanism that predisposes animals to attend to other animals (Simion, Regolin & Bulf, 2008)
The importance of social cues
Social cues aid in learning key social skills
Interpreting a social partner’s behaviour & understanding social scenarios assist integration into a social group (Mattson, 2014)
Kuhl, Tsao & Liu (2003)
32 American infants
Learning Chinese words either with live exposure or tv exposure
Infants who received the Chinese sessions showed significant effect of learning in the live condition only
Children weren’t able to learn Chinese words with tv exposure
Eyes and gaze in infants
Within their fist week babies direct their attention to the eyes (Maurer, 1985)
Can follow gaze by 3 months (Scaife & Brunner, 1975)
By 12 months, they can orient their attention to the location of a gaze (Tomasello, 2009)
Farroni et al (2002)
17 new-borns (24hr - 120hr)
Showed images of direct or averted gaze
Found they spent longer looking at the direct gaze image and more likely to move back to the eyes
Gaze cueing
When we see someone move their gaze we move our own so that we are both looking at the same location
Investigated using cueing paradigms
Cueing paradigms (Posner, 1980)
Adapted to investigate gaze cueing
Posner-type cueing paradigms
Show that ps are:
- Sig faster to detect target when it is in the same location shown by the gaze cue
- Slower to detect a target when its in a different location
Known as the GAZE CUEING EFFECT
Why does the gaze cueing effect happen and why is it important?
When we see the cue we move our eyes in the same direction
We are faster to find the targets if they are in the same place as the cue
Joint attention:
Communicates attention
Alerts us to important aspects of the environment
Pre-cursor to development of ToM
Mundy & Newell (2007)
Real world implications of social attention and gaze cueing
Direct our attention to important info in environment
Helps us plan our own actions
Gives us an insight into other peoples intentions
Reciprocal eye contact and attention allows us to fit into society
Methods for assessing social attention
- Eye-tracking
- EEG
- fMRI
EEG
Electroencephalogram
Measures electrical signals generated by the brain through electrodes on the scalp
fMRI
Nummenmaa & Calder (2009)
Many brain regions implicated in social attention:
- Automatically follow gaze? - Parts of the attention network (goal-directed and exogenous attention)
- Areas responsible for coding gaze direction, eye contact, etc (Amygdala/hippocampus)
- Areas involved with facial identity recognition (fusiform gyrus)
