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? Scheck and Nelson (2005) hypothesized JOLs form a psychological anchor between 30 and 50% of correct recall, explaining why overconfidence with practice shifts to underconfidence. → Bol L and Hacker DJ 2012

q2 · i? · theoretical · r3
Narrative review attributing to Scheck and Nelson (2005) the hypothesis that "people form a psychological anchor for their JOLs somewhere between 30 and 50% of correct recall," used to explain the underconfidence-with-practice effect. No effect sizes are printed.
"Scheck and Nelson (2005) hypothesized that people form a psychological anchor for their JOLs somewhere between 30 and 50% of correct recall and adjust their JOLs either upwards or downwards based on whether performance is above or below this band."

Related Claims¶
- Delayed JOL bias: multiple text readers are underconfident, rereaders overconfident at one day, and single readers overconfident at one week — related
- Calibration of JOLs shifts toward underconfidence across learning cycles for action phrases under both verbal and enactive encoding, without first-cycle overconfidence — related
- JOL magnitudes decline across successive lists in both JOL groups, reflecting learners' belief that recall decreases with continued new learning — related
- The now-self functions as an anchor in HPT: participants began in now-self and frequently returned to it — related
