No outcomes of these gambles were presented during scanning, but after the scan three gambles were selected at random and played for real money.

In one (probabilistic) problem, the labels were probabilistically related to each set of cards. In another (deterministic) problem, the labels were deterministically related to each set of cards. After learning, subjects participated in an event-related block of judgment only (no feedback) in which they were presented with stimuli from both of the training problems. Tasks and Conditions: 001 Probabilistic classification task 001 Probabilistic classification trials 002 feedback 002 deterministic classification 001 Deterministic classification trials 002 feedback 003 classification probe without feedback 001 Classification trials: Probabilistic 002 Classification trials: Deterministic Investigator Info Investigators: Aron, A.R.

Digital Document: fnins-06-00080.pdf Study Metadata Sample Size: 16 Scanner Type: Siemens Allegra 3T Sharing License: PPDL Accession Number: ds000001 https://academictorrents.com/download/30a8653b160b2c4f8d7e42d2070ebb1438673b2c Here we present a test-retest dataset of functional magnetic resonance imaging (fMRI) data acquired at rest. 22 participants were scanned during two sessions spaced one week apart. Each session includes two 1.5 mm isotropic whole-brain scans and one 0.75 mm isotropic scan of the prefrontal cortex, giving a total of six timepoints. Additionally, the dataset includes measures of mood, sustained attention, blood pressure, respiration, pulse, and the content of self-generated thoughts (mind wandering). This data enables the investigation of sources of both intra- and inter-session variability not only limited to physiological changes, but also including alterations in cognitive and affective states, at high spatial resolution. The dataset is accompanied by a detailed experimental protocol and source code of all stimuli used. Please subscribe to for important annoucements.
