About this trial

The goal of this clinical is to learn how the brain supports different kinds of memory decisions in healthy young and older adults. The main question it seeks to answer is: Do older adults make memory decisions by integrating across experiences?

Young (aged 18-30 years) and older (aged 65-80 years) participants will complete a memory task while undergoing functional MRI to measure their brain responses.

Researchers will compare brain measures of integration in older adults to those of young adults to see if integration increases in older age.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Either aged 18-30 years (young adults) or aged 65-80 years (older adults) (self-report)

Fluent in English (self-report)

Right-handed (self-report)

Cognitively healthy (self report verified by score > 24 on Montreal Cognitive Assessment)

Disqualifiers

Self-reported neurological disorder (e.g., Alzheimer's or Parkinson's disease)

Self-reported uncontrolled hypertension, diabetes, or thyroid disorder

Having conditions or devices that are unsafe for MRI (assessed via imaging center's MRI safety screening form)

Self-reported difficulty lying still on one's back for 1-2 hours

Trial design

Design model

Single group

Treatments tested in this trial

  • Memory decision type

    Behavioral

    Subjects will be probed to either remember an association they saw directly during the study phase or to make an inference across indirectly associated items.

Trial outcomes

Primary outcomes

1

Behavioral memory responses

Participants will complete the study and test phases of a memory-based inference task designed by the investigators. The investigators will focus on the accuracy of decisions (0-100% scale with higher scores meaning better memory) and how long it takes to make correct decisions (in seconds, faster responses mean less cognitive processing needed).

Time frame
Session 2 (experimental session)
2

Neural memory responses

Investigators will measure the neural underpinnings of direct memory and the ability to make inferences.
