THE ROLE OF WORKING MEMORY AND AGE EFFECTS
Gaze following is understood to be an automatic and reflexive process. Despite this, older participants don't tend to follow gaze like young participants. If older participants are managing to inhibit gaze following, then increasing their cognitive workload will make such inhibition more difficult. Dual tasks are often used to increase cognitive load, requiring participants to complete two tasks simultaneously.
Several different versions of the dual task method could potentially be used. For example, participants could be asked to complete the gaze following task used in the first experiment, whilst also listening to and recalling a string of numbers, as long as the task increases the cognitive load.
If older participants are somehow inhibiting the automatic process of gaze following, the increased cognitive load will make this more difficult. As such we might expect that older participants then begin to automatically follow gaze in a more similar manner to younger participants.
Specific aspects of this experiment are yet to be confirmed, as they will rely on the results of the first experiment (Ageing and gaze following).
