Overview of different behavioral indices used to describe perception performance and to quantify APC

AbbreviationFormulaDescriptionProperties
NTVNTV = arg(f = 0.75 * max_d_prime)Number of noise dots in the mask with preserved biological motion detection.Higher NTV reflects better performance.
No relation between test and baseline condition (4 values per participant).
IntIdxEmbedded ImageQuantifies the relationship between test and baseline condition.No influence of motor execution on perception: IntIdx = 0
Susceptible to dual task effects (two values per participant and patient).Facilitatory influence of motor execution on perception: IntIdx > 0
Inhibitory influence of motor execution on perception: IntIdx < 0
APCIdxAPCIdx = IntIdxsynchronousIntIdxasynchronousUnifies the IntIdx for both delay conditions resulting in one value to quantify the APC that is needed for the lesion symptom mapping.Unaffected APC: APCIdx ≥ 0
Unaffected by dual task effects (one value per participant and patient).Affected APC: APCIdx < 0
