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.
q1 i? Sevdalis et al. argue that individual differences in visual representation strength determine how MP impacts performance, suggesting groups be separated on imagery strength using tools such as the Mental Imagery Questionnaire. → Snelgrove Huon; Gabbott Ben 2020
q1 i? MP delivery varied across reviews: groups, one-to-one, video and written scripts, formally taught, self-directed at home, and embedded in relaxation, talk-aloud protocols or expert teaching, making impacts of MP itself hard to discern. → Snelgrove Huon; Gabbott Ben 2020 (2)

q1 · i? · review · r3
The SREA reports, citing Sevdalis et al., that "individual differences across the population in visual representation strength determines how MP impacts performance", with groups needing separation on imagery strength via validated tools such as the Mental Imagery Questionnaire. This is the review's attribution, not a new test.
"Sevdalis et al. [41] argue that individual differences across the population in visual representation strength determines how MP impacts performance."

q2 · i? · review · r3
Synthesis of MP content and process across the six reviews: delivery modes ranged from group and one-to-one delivery, video and written scripts, to self-directed home practice and embedding in relaxation or warm-up routines. The authors conclude "it was difficult to discern within and across the reviews the exact nature of the impacts of MP".
"As a result, it was difficult to discern within and across the reviews the exact nature of the impacts of MP. Or rather it was difficult to see the boundaries of MP with other kinds of stimuli to shape performance."
Discussion¶
Related Claims¶
- Preoperative mental practice and mental imagery enhance MIS surgical performance — related
- Concreteness, imagery, and verbal associative processes play major roles across multiple educational domains — a broader claim this one bears on
- Imagery and perceptual illusions each comprise multiple factors rather than the single CHC factors — related
- Evidence for transfer and long-term impact of mental practice is sparse but includes positive trends: combined MP plus physical practice improved suturing transfer, and mental rehearsal lowered endovascular error rates — related
