Thesis abstract

This thesis comprises three studies investigating variables affecting restrictive stimulus control and observation responses, often associated with attention, using matching-to-sample (MTS) procedures with complex stimuli.

Studies 1 and 2 found that restrictive stimulus control, also called selective attention, is affected by various experimental conditions that have not been previously investigated.

Study 1 shows that a time delay in training affects restrictive stimulus control. Study 2 found that the direction and manner in which stimulus-stimulus relations were trained influenced restrictive stimulus control.

Study 3 analyzed eye movements to abstract and meaningful stimuli and found that meaningful stimuli reduced fixation time and transitions between stimuli.

The thesis highlights the importance of compound stimuli, demonstrating that variables such as time delay, training structure, and meaningful stimuli influence restrictive stimulus control and observational responses.

The paper also emphasizes the significance of incorporating eye-tracking technology to better understand how individuals learn in MTS procedures. The findings suggest that eye movements can provide additional insights not captured by looking at accuracy and reaction time alone.
