Nicotine modulation of information processing is not limited to input (attention) but extends to output (intention).

ABSTRACT:

Rationale

Nicotine influences many cognitive processes, especially those requiring high attentional loads, yet the impact of nicotine on all aspects of information processing has not been well delineated.

Objective

The aim of the study was to determine the relative behavioral and functional effects of nicotine on dissociable aspects of information processing (i.e., selective attention and motor intention).

Methods

Adult smokers (N = 25) and healthy controls (N = 23) performed the intention/attention task (IAT) twice, during functional magnetic resonance imaging. The IAT assesses the relative differences in performance evoked by prime stimuli that provide information regarding either the correct hand with which to respond (i.e., intentional primes) or the likely locati
