Auditory–Visual stimuli: Effects on derived relations with compound stimuli

Abstract

This research explored the effect of teaching conditional discriminations with three procedures on the derivation of 36 stimuli relations (derived relations). The stimuli used consisted of three characteristics musical instruments, along with the corresponding picture. In the first experiment six university students were trained with simple stimuli and tested with compound auditory–visual samples; therefore, a one‐to‐many structure was used. In the second experiment, auditory stimuli were replaced by visual stimuli, for the samples used, for new students. A third experiment was implemented with an extra phase of training with compound stimuli for six new students. The structure of the experiments was: pretests (Xbcd–A; Xacd–B; Xabd–C; Xabc–D), training (A–B; A–C; A–D), and posttests (same as pretests). The difference between these conditions was the kind of stimuli used and a new phase of teaching used in condition 3: (Xbcd–A). The results indicate that training with simple stimuli on discriminations that include stimuli that are easy to discriminate from each other (words and sounds) is a sufficient condition for good posttest performance. However, when comparisons are made difficult (words only), participants show better performance on new tests if they have a learning history with compound stimuli.

El Efecto del Control de Estímulo Durante el Emparejamiento en la Emergencia del Naming Bidireccional

“…A diferencia de otros estudios sobre equivalencia de estímulos, que implicaban tareas de discriminación condicional (e.g., Guerrero et al, 2020), así como estudios específicos sobre naming que han estudiado el componente de escucha (e.g., Horne et al, 2004;Pérez-González et al, 2014), en los cuales los participantes debían tocar o señalar un estímulo de comparación en las tareas de selección, en el presente trabajo la respuesta de selección consistió en nombrar un número que acompañaba a la figura. Esta forma de respuesta en las pruebas de selección, la automatización de la presentación de los estímulos durante el emparejamiento, las pruebas y la descripción de las instrucciones facilitó que los dos experimentos pudieran llevarse a cabo a distancia en formato en línea.…”
