Effects of acute nicotine on event-related potential and performance indices of auditory distraction in nonsmokers.

What Was Tested

The paper reports a study of Therapeutic nicotine (patch, non-peptide), published as a randomized controlled trial.

Although nicotine has been purported to enhance attentional processes, this has been evidenced mostly in tasks of sustained attention, and its effects on selective attention and attentional control under conditions of distraction are less convincing.

Who Took Part

The age groups tagged for this paper are young adults and adults, both men and women.

How the Study Was Run

In design terms this was a randomized, double-blind, placebo-controlled and crossover study.

Because people in this Therapeutic nicotine (patch, non-peptide) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Neither the participants nor the staff measuring them knew who was on Therapeutic nicotine (patch, non-peptide), so expectations could not easily colour the readings.

A placebo (an inactive look-alike) gave the Therapeutic nicotine (patch, non-peptide) group a baseline to be compared against.

Each person switched between Therapeutic nicotine (patch, non-peptide) and the comparison at some point, usually with a gap in between.

This study investigated the effects of nicotine on distractibility in 21 (11 males) nonsmokers with event-related potentials (ERPs) and behavioral performance measures extracted from an auditory discrimination task requiring a choice reaction time response to short- and long-duration tones, with and without imbedded deviants.
