P300 correlates of inspection time

The chronometry of mental ability: An event-related potential analysis of an auditory oddball discrimination task

“…No amplitude or latency effects were reported. Subsequently, using the same stimulus parameters, Alcorn and Morris (1996) observed larger P300 amplitude for HA, but no effects with the slope measure were reported. For Burns, Nettlebeck, and Cooper (2000), HA was associated with shorter latency for early ERP waves, specifically P1, N1 and P2.…”

Intelligence and information processing during an auditory discrimination task with backward masking: An event-related potential analysis.

“…In both of these approaches, the variation in the interstimulus interval that each participant receives may be a confounding variable in the comparison of individual ERP waveforms. Alternatively, ERP averages can be obtained by averaging within a block of trials for each interstimulus interval with all participants receiving the same range of intervals (e.g., Alcorn & Morris, 1996). In the present research, a similar approach is followed with blocks of 70 trials averaged for a range of three intertone intervals (ITIs).…”

P3b correlates of inspection time

“…The duration of a stimulus varies, and the stimulus is backward-masked. The mask interrupts or erases iconic storage and precludes target identification from the iconic image after the target has physically offset ( Alcorn and Morris, 1996 ). The participant’s performance can be affected by the duration of the stimuli, which increases from near-to-chance at very brief durations to near-perfect responding at longer stimulus exposure durations ( Deary, 1993 , Walsh et al, 2017 ).…”

“…The participant’s performance can be affected by the duration of the stimuli, which increases from near-to-chance at very brief durations to near-perfect responding at longer stimulus exposure durations ( Deary, 1993 , Walsh et al, 2017 ). Individual differences in the efficiency of information processing assessed by this task were correlated moderately with differences in higher cognitive abilities and intelligence ( Alcorn and Morris, 1996 , Crawford et al, 1998 , Deary, 1993 , Deary, 1995 , Deary, 2001 , Deary et al, 1991 , Deary and Stough, 1996 , Egan, 1994 , Grudnik and Kranzler, 2001 ; Liu & Shi, 2003; McGarryroberts et al, 1992 ; Nettelbeck & Rabbitt, 1992 ), for a meta-analysis, see Grudnik and Kranzler ( Grudnik & Kranzler, 2001 ).…”

“…The P3b is a task-evoked ERP component that occurs about 300 ms after stimulus onset, has a positive polarity, and is largest at parietal electrode sites ( Basareroglu et al, 1992 , Steiner et al, 2013 , van Dinteren et al, 2014 ). To our knowledge, only two studies have reported that the amplitude of P3, but not its latency, was correlated with IT ( Alcorn and Morris, 1996 ; Zhang et al, 1989). Alcorn and Morris found that the P3 amplitudes at the temporal and occipital sites were strongly correlated with IT as well as with Raven’s Standard Matrices ( Alcorn and Morris, 1996 ).…”
