One Inference, Four Failure Modes: Formal Models of Why Pain Location Fails
Adam Y. Shavit
Patient-reported pain location is diagnostically decisive for some presentations and nearly uninformative for others. A companion paper argues this is not one gradient of diagnosti…
Binding-Motivated Contextuality: A Cross-Domain Cyclic Test in Perception and Judgment
Adam Y. Shavit
Psychophysics and decision research study perceptual binding and judgment contextuality separately. We argue a binding-motivated perceptual task and judgment contextuality are scor…
The 11/6 supremum of the Wang-Sitters rounding scheme for graph balancing
Adam Y. Shavit
Wang and Sitters' 11/6-approximation for graph balancing (each job allowed on at most two machines) is not one algorithm but a set of permitted executions. Step 1 may return any fe…
A minimum witness for the 3/2 configuration-linear-program gap in two-weight graph balancing, unique at its size
Adam Y. Shavit
Restricted assignment minimizes makespan, the busiest machine's load, when each job has one size and a set of allowed machines. Its tightest studied relaxation is the configuration…
Minimum-makespan completion and vertex selection leave the Wang-Sitters constant at 11/6
Adam Y. Shavit
Wang and Sitters' rounding scheme for graph balancing (each job allowed on at most two machines) keeps the makespan, the busiest machine's load, within 11/6 of the optimum, and a c…
Two base rates, two weights: base-rate neglect has a second axis
Adam Y. Shavit
Base-rate neglect is usually treated as one mistake: giving the prior too little weight. Turning co-occurrences into a judgment takes two base-rate corrections, not one: weighting…
Three Failures of Pain Location: Why Its Diagnostic Utility Is Three Quantities, Not One
Adam Y Shavit
Patient-reported pain location is diagnostically decisive for some presentations and nearly uninformative for others. The prevailing account treats this as one gradient of diagnost…
Perceived vertical and eye level as one orientation process: a closed-form account of the Li-Matin combination rules for egocentric space
A. Y. Shavit
Li and Matin (2005a, 2005b) reported three regularities of the induced visually-perceived vertical (VPV), the direction judged upright. For small tilts, a peripheral line shifts it…
