Mapping non-native pitch contours to meaning: Perceptual and experiential factors

Publication date: April 2019Source: Journal of Memory and Language, Volume 105Author(s): Jessica F. Hay, Ryan A. Cannistraci, Qian ZhaoAbstractInfants show interesting patterns of flexibility and constraint early in word learning. Here, we explore perceptual and experiential factors that drive associative learning of labels that differ in pitch contour. Contrary to the salience hypothesis proposed in Experiment 1, English-learning 14-month-olds failed to map acoustically distinctive level and dipping labels to novel referents, even though they discriminated the labels when no potential referents were present. Conversely, infants readily mapped the less distinctive rising and dipping labels. In Experiment 2, we found that the degree of pitch variation in labels also does not account for learning. Instead, English-learning infants only learned if one of the labels had a rising pitch contour. We argue that experience with hearing and/or producing native language prosody may lead infants to initially over-interpret the role rising pitch plays in differentiating words. Together, our findings suggest that multiple factors contribute to whether specific acoustic forms will function as candidate object labels.

The objective of this study was to test the hypothesis that worse prognosis in blacks with MF is mediated by higher disease stage at diagnosis and by earlier disease onset in black females. METHODS: We conducted retrospective chart review of 337 patients with clinically-suspected MF seen at Johns Hopkins between 2003 and 2018, requiring biopsy-proven disease for study inclusion. Patient demographics, initial stage/percent body surface area (BSA) involvement, pathology type, flow cytometry results, and treatment regimens were recorded. RESULTS: Of 303 patients with confirmed MF, 166 (55%) were white, 107 (35%) black...

ConclusionsThe RF-EBT3 seems to be a detector suitable for measurements of the dose at the surface. This suggests that RF-EBT3 films might be good candidates as detectors for in vivo dosimetry.

The formulated relations can easily estimate the irradiated isodose volume if the TRAK and dose are known. The C0-60 can also be used for brachyt...
