Binding and retrieval are considered two central processes of action control. Hereby, binding refers to the integration of features into an event file that occur in a stimulus-response episode. Retrieval, in turn, occurs when one of the features involved is repeated. If features of the previous and the current episode only partially match, a conflict between the retrieved previous and the current response must be resolved, resulting in performance costs: the binding effect. Based on this, interindividual differences in binding behavior have been linked to age- and disorder-related phenomena. For example, older people and children have been found to show larger binding effects than younger people, and similar patterns have been reported for Tourette's patients versus non-clinical samples. However, according to recent approaches, the processes of binding and retrieval occur independently. This raises the question to which processes the observed interindividual differences can be attributed to: Binding, retrieval, or both. Aiming to distinguish between these components, we will present data of an online study in which two age groups (20-30 and 50-70 years) completed three types of tasks that should lead to binding effects: A non-specific binding task, a salience-oriented binding task to manipulate the binding component, and a task with variable onset times in the probe to manipulate the retrieval component. Here, we expect differences in terms of binding and retrieval behavior between the two age groups. The results are discussed in terms of possible influencing factors such as fluid and crystalline intelligence, age-related neurophysiological changes, and cognitive strategies.
