NARPS - T54A

Description: The final images included are the unthresholded z-stat (obtained from FSL FLAME1) and unthresholded TFCE-stat (obtained with FSL randomize [1-p]) (unthres). We also include the thresholded version of these images (thresh). terms EQR: Equal Range, group indicator for group presented with the same range of values of losses and gains in a series of mixed gambles EQI: Equal Indifference, group indicator for group presented with a range of values for losses half of the range for gains in a series of mixed gambles Gains: Images associated with a parametric change in Gains during the series of mixed gambles. Losses: Images associated with a parametric change in Losses during the series of mixed gambles. _pos:Images are the result of a contrast positively correlated with Gains/Losses _neg:Images are the result of a contrast negatively correlated with Gains/Losses NARPS HYPOTHESES #, (image_tag), (description) 1, EQI_GAINS_pos, Positive effect in VMPFC- for the equal indifference group 2, EQR_GAINS_pos, Positive effect in VMPFC-for the equal range group 3, EQI_GAINS_pos, Positive effect in STR-for the equal indifference group 4, EQR_GAINS_pos, Positive effect in STR-for the equal range group 5, EQI_LOSS_neg, Negative effect in VMPFC- for the equal indifference group 6, EQR_LOSS_neg, Negative effect in VMPFC- for the equal range group 7, EQI_LOSS_pos, Positive effect in AMYGD- for the equal indifference group 8, EQR_LOSS_pos, Positive effect in AMYGD- for the equal range group 9, EQR_gr_EQI, Greater response to losses in AMYGD for EQR vs EQI condition **For simplicity and to accord with the NARPS instructions, the image tags above were replaced with "hypo#". **We have also included the group-level cope and varcope images corresponding to the hypotheses above. **Finally, we have also included the subject-level cope and varcope images for the the parametric effects Gains and Losses.
