Comparisons in Influence Conditions using In High and Low Suggestibility Groups.

<p>All <i>p</i> values were corrected using Tukey's multiple comparison test. Cohen's <i>dz</i> values >0.2 and <i>p</i> values <0.05 are indicated in bold text.</p

Associations between BIS total score and (A) percentage of impulsive choices, and (B) change in k value, both under the ‘no influence’ condition.

<p>There were no slope differences between the ‘no influence’ condition and any influence conditions. Dotted lines represent the 95% confidence interval of the associations.</p

Association between increases in impulsive choices with impulsive influence and self-reported susceptibility to influence.

<p>Significant associations are indicated in bold text.</p

Percentage impulsive choices and k values by influence type.

<p><b>Panel A and B, Left.</b> Each point represents an individual participant's percent of SS choices (top panel), or k value (bottom panel) after exposure to each of influence type. The horizontal bar shows the mean of the group during each influence type. <b>Middle</b>. Each bar shows the 95% confidence intervals of the difference between the means of each pair of conditions in percent of SS choices (top panel), or k value (bottom panel). The points represent the mean of each difference. Impulsive influences are generally shifted to the right, indicating that impulsive responding increased under impulsive influence conditions. <b>Right</b>. Each point and dotted line represents an individual participant's percent of SS choices (top panel), or k value (bottom panel) after exposure to impulsive influence (minus no influence ‘none’) and non-impulsive influence (minus ‘none’). Paired t-tests indicate a significant difference of influence type on percentage of SS choices, and a non-significant effect on k values.</p

Depiction of Social Influence Manipulation.

<p>After showing participants their option (<b>Panel A</b>), four types of influence could be presented (Impulsive, Non-impulsive, Split, and None) (<b>Panel B</b>), as shown in the lower panel. Participants were then asked to make their choice. (<b>Panel C</b>) and then had a 2 second rest between trials (<b>Panel D</b>). Please see Methods for detail.</p

Associations between percentage of SS choices and (A) MISS total suggestibility score and (B) Peer Conformity Subscale score.

<p>Dotted lines represent the 95% confidence interval of the associations.</p
