Abstract
Action control (i.e., response inhibition) is a crucial ability for adaptive responding but it may
be compromised in threat-related situations. The present research investigated if a stop-signal
training would improve the efficiency of response inhibition and reduce shooting errors in
high-threat circumstances. In the pre- and post-training sessions all participants (N=44)
performed a stop-signal shooting task. In between there was a stop-signal training destined for
the experimental group (n=31), and Go/NoGo training for the control group (n=13). The
results showed that from pre- to post-training session response inhibition was improved (i.e.,
decreased stop-signal reaction times [SSRT]; b=12.96 (2.16), 95% CI [ 8.82, 17.09]; X²
(1)=35.87, p<.001) and shooting errors were reduced (i.e., increased response accuracy; b= -
0.11 (0.02), 95% CI [-0.15; -0.08]; X²=45.29, p<.001). However, contrary to what was
hypothesized, no difference between training groups was found on both, SSRT (p=.54) and
response accuracy (p=.39). The present research is the first that investigated the direct link
between improvement in response inhibition and shooting performance.
