| Abstract/Results: | The Affect–Integration–Motivation (AIM) framework was proposed to clarify how brain circuits that support
decision-making are altered by aging (Samanez-Larkin & Knutson, 2015). According to this framework, choices
are preceded by affective, integrative, and motivational processes, which may all be affected by aging. The Mon-
etary Incentive Delay (MID) task allows tapping into several mechanisms proposed by the AIM framework, and
the present registered report aimed to explore the temporal resolution of the EEG to find the neural correlates of
age differences in such mechanisms, including gain/loss anticipation, value integration, motivational processes
underlying motor choice, as well as processing of positive/negative rewards. The electrophysiological data were
recorded from 77 participants (20–80 years old), and we analyzed the Cue-P3, Contingent Negative Variation,
target-P3, Feedback-related Negativity, and the Feedback-P3. The results support the AIM framework, suggest-
ing that aging altered affective processes (as shown by a significant reduced cue-P3 in the older group), while
preserved integration and motivation processes. However, despite a general lack of significant group by domain
interactions across the ERPs analyzed, the results of the planned comparisons are suggestive of a preserved pro-
cessing of gains and affected processing of losses during aging. This conclusion requires further replication with
larger samples, but our study shows that future research may profit from decomposing decision processes to
understand how biological aging affects decision making.
