The fMRI data are moved to Dropbox due to the revised storage space limitation of OSF. The Dropbox link for the fMRI data: https://www.dropbox.com/sh/0roujiwwymnu07j/AACB0kNfgDo0tjnr8usZdMx9a?dl=0

**fMRI**
First-level GLM is performed using FSL. The relevant .fsf file can be found in the "fsf file" folder. For the FSL, you will also need timing files which can be obtained via running the CreateTimeMatrices.m file that can be found in the "Analysis Code" folder.
First isolate ROI activity to reduce file size.

Other analyses are listed below in the order of appearance in the paper.
Note: The term "Orienting Period" in the paper is referred to as the "Decision Period" in the code below.

Analysis (no figures):
(i) using separate image period templates for the memory-guided vs. explicitly instructed tasks as opposed to a common template;

2. PlotRSA_DecisionPeriod_SameCondTemp.m
(ii) using image period templates that include both valid and invalid trials as opposed to valid trials only, and
1. CalculateRSA_DecisionPeriod_ValidAndInvalid.m
2. PlotRSA_DecisionPeriod_ValidAndInvalid.m
(iii) analyzing only those decision periods that followed either a stay cue or a switch cue (i.e., excluding decision periods following no-cue trials).
1. CalculateRSA_DecisionPeriod.m (note that this should already be ran for the “Decision Period RSA” if you are going in order)
