The continuous performance test (CPT) is a usual laboratory test measuring impulsivity, and it requires the individual to make rapid evaluation/discrimination of presented stimuli to decide whether or not to respond.
Further stimuli need to decide the fate of these immature cells, which could be provided by in vivo retinal environment after cell transplantation [ 30].
Subjects were presented simultaneously with one visual and one auditory stimulus and were instructed to decide whether these stimuli referred to the same object or not.
In this task, the subjects heard the beginning of a well-known tune (31 stimuli), and had to decide whether the second part matched (i.e. was the right end) or not.
As all vowel categories exhibited acoustic variance, subjects had to map stimuli onto vowel categories to decide whether a given stimulus is a target or not, i.e. subjects had to maintain a phonological processing mode throughout the experiment.
Participants were encouraged to use the time before the stimulus on each trial to decide which task to perform.
This domain is involved in processes such as driving and learning, as it involves perceiving stimuli and quickly being able to decide whether a given stimulus is important for the present situation or should be discarded.
For each modality, 48 trials (24 famous, 24 unfamiliar) were presented; each stimulus was presented once, and the task was to decide if the stimulus was familiar in a forced choice ('yes – no') protocol.
Hence, we need to decide which stimulus attribute has the same contour lines as the ones corresponding to n.
Stimulus generalization, or the ability to decide that two objects, though readily distinguishable, are similar enough to afford the same consequence [1], could help animals adjust to variation in odor signals without losing sensitivity to key inter-stimulus differences.
