Mnemonic Similarity Task - Set C
The Mnemonic Similarity Task (MST) is an object recognition memory task originally called Behavioral Pattern Separation Task (Stark et al, 2013) and renamed in 2015. It can be used to study memory performance over the life-span. This script uses stimuli set C.
Mnemonic Similarity Task - Set D
This MST script uses stimuli set D.
Mnemonic Similarity Task - Set E
This MST script uses stimuli set D.
Mnemonic Similarity Task - Set F
This MST script uses stimuli set F.
Optimized Mnemonic Similarity Task (oMST) - Set 1
The oMST is a continous form of the classic Mnemonic Similarity Task (MST), an object recognition test sensitive to changes in memory performance. Whereas the MST uses a two phase testing paradigm, the oMST combines both phases into a single one (thus it's also referred to as the continuous MST), cutting down on testing time. This script provides the oMST run with stimuli set 1 (3 different trial orders provided)
Optimized Mnemonic Similarity Task (oMST) - Set 2
This script runs the oMST with stimuli set 2 (3 different trial orders provided)
Optimized Mnemonic Similarity Task (oMST) - Set 3
This script runs the oMST with stimuli set 3 (3 different trial orders provided)
Optimized Mnemonic Similarity Task (oMST) - Set 4
This script runs the oMST with stimuli set 4 (3 different trial orders provided)
Optimized Mnemonic Similarity Task (oMST) - Set 5
This script runs the oMST with stimuli set 5 (3 different trial orders provided)
Optimized Mnemonic Similarity Task (oMST) - Set 6
This script runs the oMST with stimuli set 6 (3 different trial orders provided)
