Detailed Descriptions

Sequence: 20688383
Description This study will apply rtfMRI neurofeedback training as an intervention method, to demonstrate that healthy older adults can be trained in volitional up-regulation of ACC activity, reducing their trust-learning deficits. The study will compromise 4 MRI sessions: 1 pre-training scan, 2 training scans, and 1 post-training scan. Number and duration of scans are based on our feasibility data showing that older adults were able to up-regulate ROI activity after two 1-h training sessions. After the post-training scan, the effects of neurofeedback training on far transfer to phishing susceptibility and exploitation risks will be assessed using PEST and our survey measures.

Name rtfMRI-guided Neurofeedback Training Name Sham Control
Description Real-time functional magnetic resonance imaging guided neurofeedback is a non-invasive procedure that provides a visual of participants' current blood oxygen-level-dependent (BOLD) signal in response to a specific task or stimulus in a targeted brain region relative to a control region. Participants use real-time neurofeedback to modulate targeted BOLD signals in their own brain. This technique is used in Study 3. The study does not assess change in a health condition. It evaluates the effect of real-time functional magnetic resonance imaging guided neurofeedback (vs. sham neurofeedback) on trust-related learning in older adults. Description Sham control is the neurofeedback that was previously recorded from a patient, a non-invasive procedure used as a placebo
