Visual evoked potentials associated with the verbal and non-verbal problem-solving processes

Effects of brief stimulus duration on the amplitude of the occipital late positive component associated with verbal and non-verbal tasks

“…These P260 amplitude changes across positions in 50 ms session seem to coincide with the findings reported by Kitajima et al(1980Kitajima et al( , 1983 in which they demonstrated larger amplitude of the P260 (P270 in their papers) at late stimulus positions using stimulus duration of 300 ms. The P260 amplitude changes in 25 ms session seem to coincide with the findings reported by Kitajima et al(1981) in which they demonstrated large amplitude at stimulus position 1 and small amplitude at stimulus positions 2-3 using stimulus duration of a fraction of a millisecond or 10ms.…”

ERP correlates to initial perceptual processing of native and foreign language characters in a habituation paradigm

“…The habituation paradigm consists of a series of stimuli, habituation, test, and dishabituation (Thompson & Spencer, 1966;Groves & Thompson, 1970;Megela, Teyler, & Hesse, 1977;Paul, 1991;Paul & Morotomi, 1996). The repetition of the habituation stimulus led to the P2 decrement (Megela, Teyler, & Hesse, 1977;Paul, 1991, Paul & Morotomi, 1996Kitajima, Murohashi, & Kanoh, 1980, 1981, and the test stimulus recovered the P2 amplitude, depending on its similarity to the habituation stimulus (Megela, Teyler, & Hesse, 1977;Paul, 1991, Paul & Morotomi, 1996. Following the above-mentioned hypothesis of Schendan et al (1998), the P2 decrement to the repeated habituation stimulus can be interpreted to reflect a decline of attentional orientation to stimuli from which new information cannot be further extracted.…”
