Task Protocols for HCP Aging

The HCP Aging study uses three customized Psychopy task scripts in its functional MRI protocol. These scripts are now available for download and use by other researchers. 

VisMotor Task

The VISMOTOR task is a simultaneous motor and visual activation paradigm. Participants view checkerboards on the screen and make motor responses (button presses) indicating what side of the screen the checkerboard shows a change in color. This task is a block design with the potential option to analyze in an event related manner. It is intended as a localizer for visual and motor networks.

Go NoGo Task

The Go NoGo Task (referenced elsewhere as the “CARIT” task, as explained below) is an inhibitory control task in which participants are instructed to press buttons for some shapes and withhold button responses to other shapes. It allows mapping of differential neural activity when response inhibition demands are high (NoGo trials) compared to freely responding with a motor action (Go). This contrast identifies brain regions important for motor response inhibition. This particular Go NoGo task contains two shapes that serve as NoGo stimuli (circle and square), and a variety of other shapes serve as Go stimuli.

This task is known in the HCP-D study as the Conditioned Approach Response Inhibition Task (CARIT), because it integrates with a different task run only in HCP-D which induced a conditioned reward association with one of the shapes. For the HCP-A project, the task is run without this manipulation. See the HCP-D Task Protocols page for more details.

Facename Task

The FACENAME task is a paired-associates memory task. Participants are asked to encode the names of different face identities in some blocks and mentally recall them in other blocks. Immediately following MRI scanning the participants provide explicit recall for face-name pairs to validate performance. This task is a block design with the potential option to analyze in an event related manner. It is intended as a localizer for encoding-related and retrieval-related neural processes.

The FACENAME task was adapted from:
