Puerto Rican Spanish (PRS) has at least three intonation contours available for marking polar questions (PQs): ¡H*L% marks an utterance as a PQ; H+L*L%, in addition to doing the former,…

Purpose: The purpose of the present study was to evaluate the new Cognitive Spare Capacity Test (CSCT), which measures aspects of working memory capacity for heard speech in the audiovisual and auditory-only modalities of presentation. Method: In Experiment 1, 20 young adults with normal hearing performed the CSCT and an independent battery of…

Infants in the early stages of word learning have difficulty learning lexical neighbors (i.e. word pairs that differ by a single phoneme), despite their ability to discriminate the same contrast in a purely auditory task. While prior work has focused on top-down explanations for this failure (e.g. task demands, lexical competition), none has…

Some argue that 1/f scaling is a general and pervasive property of the dynamical substrate from which cognitive functions are formed. Others argue that it is an idiosyncratic property of…
