When the above article was first published online, data appeared incorrectly in Table 1 and on page 422 under the section Impulsivity.

Notes: N=Number of observations; SD=Standard deviation.¹ Minimum and maximum values are identical in t₁ and t₂. ² Cumulated detection experience is 1.66% in the full sample and 7.82% in the Plagiarist subsample. ³ As noted earlier, impulsivity is assumed to be stable and was therefore only assessed in t₁.

To highlight these changes, they appear underlined and bolded below. They do not appear as such in the corrected table.

Impulsivity

For ease of interpretation, we then normalized the factor score to the interval [0, 1] so that ‘0’ indicates an individual with lowest impulsivity and ‘1’ an individual with highest impulsivity.
