Subclaims¶

q1 i? Comparing activation signatures between novice and expert on a task may reveal differences in regions, order and timing of activation, which can be used to refocus an intervention on the factors of expert performance. → Robert Colvin 2016

Evidence¶

q1 · i? · theoretical · r3

Theoretical argument, not a tested result: the article proposes that novice-expert signature comparison can inform optimisation, illustrated hypothetically with novices experiencing bottlenecks in a visual processing region during a geometry task. No data are reported.

"A comparison of activation signatures between novice and expert on a task may show that the same regions are activated in the same order, but with shorter (and/or longer) times spent in each. Alternatively, experts may show activation in other regions"

Related Claims¶

• Comparing activation signatures across tasks can suggest generalisation of an intervention to a new domain — related
• Comparing how activation signatures develop can identify harmonious interventions for integration — related
• Expert teachers' classroom perception appears knowledge-driven while novices' appears image-driven, guided by salient visual features — related
• Experts have reduced access to memory traces of their own cognitive processes due to automatization, and large domain knowledge can disadvantage performance on certain tasks — related
• Experts verbalized fewer SRL phases overall than novices during clinical reasoning, with feelings of uncertainty almost absent among experts — related
