Análisis ROC y z-ROC en memoria de reconocimiento: modelos continuos, de umbral y asimétricos / ROC and z-ROC analysis in recognition memory: Continuous, threshold, and asymmetric models

En esta investigación aplicamos la característica operativa del receptor (ROC) para evaluar la memoria de reconocimiento de ítems mediante palabras de clase abierta (CA) y clase cerrada (CC). El objetivo consistió en evaluar procesos y modelos de la memoria a partir del tipo de estímulos utilizados: palabras en lengua española, clasificadas según características gramaticales. En el registro de datos se aplicó una escala de estimación (EE) con el objeto de obtener los niveles apropiados de respuesta. Se obtuvieron diferencias estadísticamente significativas entre el procesamiento de ambos tipos de palabras. Obtuvimos modelos de umbral, continuos y de varianza desigual. Con ello pudimos contribuir a la resolución de la controversia actual sobre los modelos más adecuados para evaluar la memoria de reconocimiento de ítems. Finalmente, se argumenta sobre la diferenciación e integración de los modelos desde un punto de vista empírico (AU)

In this research, we applied the operating characteristic of the receiver (ROC) to evaluate item-recognition memory by means of open class words (CA) and closed class words (CC). The purpose was to evaluate memory processes and models, according to the type of stimuli used: words in Spanish, classified according to grammar characteristics. To register the data, a rating scale was applied to obtain the appropriate response levels. Statistically significant differences between the processing of both types of words were obtained. We evaluated models of threshold, continuous, and unequal variance. As a result, we could contribute to the resolution of the present controversy about the models adapted to evaluate the memory of item recognition. Lastly, the differentiation and integration of the models from an empirical point of view is discussed (AU)
