NONHUMANS HAVE NOT YET SHOWN STIMULUS EQUIVALENCE

Protons for Oropharyngeal Cancer Have Not Yet Justified Their Promise.

Our colleagues had a tough job to do. Using patientreported outcomes (PRO) instruments that may have lacked sensitivity to elicit subtle differences in outcomes important to patients, they compared PROs in oropharyngeal cancer patients treated with intensity modulated proton therapy (IMPT) versus those in patients treated with intensity modulated photon therapy (IMRT) (1). Sio et al hypothesize...

Acquired equivalence changes stimulus representations.

Acquired equivalence is a paradigm in which generalization is increased between two superficially dissimilar stimuli (or antecedents) that have previously been associated with similar outcomes (or consequents). Several possible mechanisms have been proposed, including changes in stimulus representations, either in the form of added associations or a change of feature salience. A different way o...

Yet Another Characterization of Strong Equivalence

Strong equivalence of disjunctive logic programs is characterized here by a calculus that operates with syntactically simple formulas. 1998 ACM Subject Classification D.1.6 Logic Programming, I.2.3 Deduction and Theorem Proving

On the dynamics of stimulus control during guided skill learning in nonhumans.

This study measured skill acquisition in the presence and absence of guiding cues in pigeons. It asked whether the speed of development of autonomy for the motor skill is influenced by the difficulty level of two guiding-cue conditions requiring the same left-right response sequence. The Follow-Red condition required a simple go, no-go discrimination (red=S+, green=S-), whereas the Red-Green co...
