Participants were instructed to detect a target phoneme (phoneme detection task).
Importantly, inattentional blindness has also been demonstrated in conditions of high perceptual load in tasks that measure detection sensitivity for an expected stimulus that participants are instructed to detect (Carmel, Saker, Rees, & Lavie, 2007; Carmel, Thorne, Rees, & Lavie, 2011; Macdonald & Lavie, 2008).
Subjects were instructed to detect whether the two hierarchical items composing a pair were identical or different.
Subjects were instructed to detect rare tactile target stimuli at the to-be-attended hand while ignoring stimuli at the other hand.
In the Detection condition, which was always administered after the Distraction condition, subjects were informed about the rule (rising/falling) and were instructed to detect deviants and to indicate them by button presses.
Therapists are instructed to detect potential breaches in the alliance.
Participants performed a visual search task and were instructed to detect whether an auditory stimulus was present or absent during the search task performance.
Observers (n = 5) were instructed to detect a small target grating (width = 1°, height = 1°, spatial frequency = 1 c/°) presented for 1000 ms at a location either 2° to the left or right of a small fixation cross.
The same holds true also with another study applying neutral expressions as deviants and happy faces as standards while the subjects were instructed to detect target faces with glasses [ 14].
To minimize possible variations in the level of attention across trials, subjects were instructed to detect a small translucent target dot that was presented briefly in any location on the screen, during concurrent central fixation.
Before each block of the memory detection test, participants practiced a block-specific list of target words and were instructed to detect and press one button whenever they recognised a target word, and press another button for any other words (buttons and response hand counterbalanced across participants).
