Active (Task-Dependent) Paradigms
|
|
|
| Contrast change |
Minimal |
Probes basic elements of sensorimotor translations, e.g., sensory evidence encoding, decision formation and motor preparation, providing dynamic measurements of each processing stage in isolation. |
| Sequence learning |
Moderate |
Assesses successive visuo-spatial sequence learning by using semantically unloaded stimuli, tracks the progress of gradual memory formation |
| Symbol search |
Complex |
A computerized version of a clinical pediatric assessment measuring processing speed capacity in a visual search task, which involves multiple perceptual decisions, short-term memory and motor response. |
Passive (Task-Independent) Paradigms
|
|
|
| Resting-state |
None |
Measures endogenous brain activity during rest. |
| Surround suppression |
Minimal |
Measures excitatory (using the steady-state visually evoked potential; SSVEP) and inhibitory (using the surround-suppression effect) neurophysiological activity during sensory processing with semantically unloaded stimuli. |
| Naturalistic viewing |
Complex |
Measures neurophysiological activity during higher-level audio-visual stimulation (movies). |
