q2 i? Each pair in the odd-ball task developed a unique set of phrases for communicating confidence, and the more rapidly a pair developed such phrases, the greater their group advantage. → Frith Chris D 2012

q2 · i? · review · r2

A linguistic analysis of the discussions in the odd-ball experiments (Fusaroli et al., as reviewed here) found each pair developed a unique confidence vocabulary, e.g. "sure, almost sure, a little uncertain, not sure, very unsure, totally unsure". Faster development of a small phrase set predicted greater group advantage.

"The more rapidly a pair developed and used a small set of such phrases for communicating confidence, the greater their group advantage."

Related Claims¶

• Two people discussing perceptual decisions can outperform the better individual, via weighted confidence sharing — a broader claim this one bears on
• The group advantage reverses when partners' abilities differ greatly, and depends on the mode of communication — related
• Sharing perceptual experiences through discussion improves individual performance beyond mere task practice — related
• Communication and coordination costs of transactive activities can annul the benefit of sharing cognitive load in a group — related
