Table 2.

EBC paradigms and measurement techniques for studies of EBC in schizophrenia.

Study Procedure type Method of eyeblink activity measurement
Taylor and Spence (54) Single-cue visual delay EBC Microtorque potentiometer mounted to lever attached to upper eyelid and polygraph recording eyelid position (69)
O’Connor and Rawnsley (55) Single-cue auditory delay EBC Light source and photoelectric cell
Spain (56) Combined visual and auditory delay (presented as 50 trials of each, order counterbalanced)
 Auditory Auditory delay EBC Electrodes placed above and below the eye; similar to electrooculography
 Visual Visual delay EBC Electrodes placed above and below the eye; similar to electrooculography
Sears et al. (57) Single-cue auditory delay EBC Infrared photobeam
Hofer et al. (58) Delay eyelid conditional discrimination learning Photocell that measured “area of the eye covered by the eyelid” (via “light reflected from the cornea”)
Stevens et al. (59) Discrimination auditory delay EBC
Marenco et al. (60)
 Trace Single-cue auditory trace EBC “Potentiometer attached to the eyelid”
 Delay Single-cue auditory delay EBC “Potentiometer attached to the eyelid”
