Q1. Do emotional faces capture our attention?
Q2. Do emotional faces direct our attention?
After the background lecture you will split into groups of three. Have a look at the experimental templates in E-prime and decide in your group which question you want to answer and which variables you wish to manipulate.
(e.g express saccade, target ellicited saccade)
There has been much argument about whether these two types of cue effect represent two distinct underlying systems.
Negative faces are easier than happy faces to pick out of a matrix of neutral faces (Hanson & Hanson, 1988; Fox et al., 2000)
Hermans, Vansteenwegen and Eelen (1999) found Ss looked more at spiders than flowers in a display at short durations. From 2000-3000 ms however the high spider-anxious Ss looked less at spiders and more at flowers. Vigilance-avoidance? Rohner (2002) found the same with pairs of faces
RTs to a probe task were faster when the probe occupied the location of an angry or fearful face (Bradley, Mogg, & Miller, 1998; Fox, 2001)
Friesen and Kingstone,1998:
They believed that gaze direction was of special significance in orienting an observer’s focus of attention.
Using schematic faces they found that participants were faster to respond to targets that were validly cued by gaze direction.
Though gaze direction was a central cue, the results were more akin to those found using a peripheral cue.
They found that fear faces produced faster responses to validly cued targets than faces with no emotion – but only in high anxiety (HA) individuals.
HAs were also slower when the fear faces had a central gaze (a neutral cue) suggesting that they had difficulty disengaging from a fear face.
A small pilot study however failed to replicate these results with anger (perhaps something to do with amygdala function? – Adams et al, 2003) .
Neutral, Fear, Anger, Disgust – Happy faces could also be arranged!
Cuing effects will be increased if more time is given to process the face before the cue appears
Vary cue validity and time from face onset to cue onset
Fear faces will produce greater cuing benefits at short SOAs
Vary cue validity, facial emotion, and SOA
Highly anxious individuals will show a greater sensitivity to cue predictability than low anxious individuals
Vary cue validity, cue predictability, and participant anxiety. Only use fear faces, or use fear and neutral faces, creating a fourth variable
