RESUMEN
Children's ability to learn words with multiple meanings may be hindered by their adherence to a one-to-one form-to-meaning mapping bias. Previous research on children's learning of a novel meaning for a familiar word (sometimes called a pseudohomophone) has yielded mixed results, suggesting a range of factors that may impact when children entertain a new meaning for a familiar word. One such factor is repetition of the new meaning (Storkel & Maekawa, 2005) and another is the acoustic differentiation of the two meanings (Conwell, 2017). This study asked 72 4-year-old English-learning children to assign novel meanings to familiar words and manipulated how many times they heard the words with their new referents as well as whether the productions were acoustically longer than typical productions of the words. Repetition supported the learning of a pseudohomophone, but acoustic differentiation did not.
RESUMEN
Se realizo un estudio prospectivo en 109 pacientes ingresadas con diagnóstico de aborto en el hospital Dr. Alejandro Cabral, San Juan de la Maguana, República Dominicana, durante el período noviembre, 1990-febrero, 1991. Dicho estudio pretende determinar las causas y evolución de los mismos. Se les practico legrado uterino a todas las pacientes y se determino que el aborto tuvo mayor incidencia en el grupo etario de 15-19 años (35.8 por ciento ); la zona rural tuvo el mayor indice de aborto provocado (13.8 por ciento ) y que en el grupo de bajos ingresos económicos se registro la mayor cantidad de embarazos no deseados (29.4 por ciento )
