P. J. Kellman, P. Garrigan, and T. F. Shipley's theory of 3-dimensional object interpolation asserts that existing data, as well as logical considerations, support the view that an identical contour interpolation process underlies the interpolation of partially camouflaged and partially occluded objects (modal completion and amodal completion, respectively). Here, the author argues that recent ...

Principles of procreative beneficence (PPBs) hold that parents have good reasons to select the child with the best life prospects. Sparrow (2010) claims that PPBs imply that we should select only female children, unless we attach normative significance to “normal” human capacities. We argue that this claim fails on both empirical and logical grounds. Empirically, Sparrow’s argument for greater ...

Two competing theories of processing of conditionals (if-then) were tested. Syntactic theories posit that people only draw inferences conforming to the logically valid modus ponens (MP) schema. Mental models theories predict that people draw MP and invalid affirming-the-consequent (AC) inferences. Three experiments tested these predictions. Participants read short stories that conformed to eith...

In their letter in the December 2010 issue, “Author Response: Bevacizumab Suppression of Establishment of Micrometastases in Experimental Ocular Melanoma” Yang et al. state that “bevacizumab has been used in mouse models of choroidal neovascularization” and quote Hua et al., for which I am the corresponding author. This is an incorrect and misleading reference. We certainly did not show that be...

WYSIWYM (What You See Is What You Meant) is a new methodology for editing knowledge representations by interacting with a generated NL feedback text which presents both the knowledge already deened and the options for extending and modifying it. This paper concerns novel problems that arise when this methodology is extended to deal with certain familiar and supposedly well-understood semantic p...
