Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? When a go/no-go task is performed alongside a partner performing the complementary part, a congruency effect returns that is absent when the task is performed alone. → Frith Chris D 2012

q2 · i? · review · r2
A reaction-time study (Sebanz et al., as reviewed here) using a spatial-compatibility go/no-go task. When a second participant took over the other response, the congruency effect returned: "spatially incongruent responses were slowed", indicating automatic representation of the co-actor's stimulus-response requirements.
"In this context, even though the original participant was still performing the identical go/no-go task, the congruency effect returned and spatially incongruent responses were slowed."
