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

Impulsivity, intelligence and P300 wave: An empirical study

“…Bazana and Stelmack, 2002;Deary and Caryl, 1997;Gurrera et al, 2005; for a critical review, see Stelmack and Beauchamp, 2001). It is noteworthy that the consistent negative relationship between P300 latency and mental ability has been reported on rather difficult sensory discrimination tasks (e.g., De Pascalis et al in press;Beauchamp and Stelmack, 2006), while the task used in the present study is characterized by a low level of difficulty.…”

“…On the other hand, recent studies suggest a positive relationship between P300 amplitude and the performance on intelligence tests or subtests (e.g. Bazana and Stelmack, 2002;Beauchamp and Stelmack, 2006;De Pascalis et al, in press;Gurrera et al, 2005;Katsanis et al, 1997;Portin et al, 2000).…”

Delayed preattentional functioning in early psychosis patients with cannabis use

“…Shorter P3a latencies are thought to reflect better cognitive performance (Beauchamp and Stelmack 2006;Polich 2007). Although users did not differ from non-using patients on IQ, when current users were separated from past users, duration of current use was associated with latency at the central site, indicating that the longer the duration of cannabis use is, the slower is the P3a latency.…”

Mental ability and mismatch negativity: Pre-attentive discrimination of abstract feature conjunctions in auditory sequences

“…This suggested that the deviant tone and masking tone were processed as a compound stimulus, i.e., a gestalt, rather than pure tone stimuli. Subsequently, the mental ability effects were replicated in a study demonstrating the influence of variation of the frequency of the masking stimuli on the ERP measures (Beauchamp & Stelmack, 2006). This confirmed that the tones and mask stimuli were processed as a compound stimulus in which the relation of tones and mask was relevant.…”

“…A comparator model of mental ability was outlined in previous work (Beauchamp & Stelmack, 2006) that integrated a model of mental speed on psychometric items (Furneaux, 1961) with a contemporary model of auditory stimulus representation (Naatanen, 1990;Naatanen, Kujala, & Winkler, 2011). A comparator construct is central to both models.…”
