File name - IRD1 and IRD2 Inhibition effect - File contains data for the 3 trial types. participant group and also values for the inhibition effect and facilittion effect for both experiments
Code- 
TT= target to target trial type
TN= target to new location trial type
TD= target to distractor trial type
Inhibition effect= TD-TN values
Faciliation effect= TN-TT
Group codes = Alzheimer's groups (AD), Mild cognitive impairment group (MCI), European participants (EP), Older South Asian participants (OSP) and young adults (YC)

Files - IRD1 cogntive assessment.sav, IRD2 cognitive assessment.sav - data for the cogntive assessments for both experiments 
code- 
digitF = digit span forwards score
digitB= digit span backwards score
digitT = digit span total score
spatialF= spatial span forwards score
spatialB= spatial span backwards score
spatialT= saptial span total score
