In this case it showed a relationship between gaze compatibility and reaction time, with this effect being present between congruent and incongruent trails, as well as incongruent and neutral trails. These results followed the overall outcome of the literate review, with incongruent trails being significantly slower then both neutral and congruent trails. This is a credible result as Friesen & Kingstone (1998) noted that humans appear to have a tendency to use gaze direction as a cue for attention. This suggests that gaze direction is fast and automatically detected, enhanced when a cue such as congruent gaze direction is present (Ansorge, 2003). Despite these significant effects, on all gaze compatibility trails the emotion expressed by the face presented did not influence either accuracy or reaction time, allowing the null hypothesis to be accepted.
Emotional expression not boosting or reducing gaze cueing effects is interesting, as this throws doubt onto the connection between this area and gaze direction. It is possible that this research has over looked another underlying link between these factors that enable them to be effective to one another on gaze cueing effects, for instance the likability the face giving the expression. This would be a useful area to extend into, as gaze cueing is an important factor to identify due to its social significance
