Relation between Conditioned Stimulus-Elicit Responses and Unconditioned Response Diminution in Long-Interval Human Heart-Rate Classical Conditioning
Previous research on electrodermal conditioning suggests that the conditioned diminution of the unconditioned response (UR) has an associative basis. The aim of this experiment was to test whether this phenomenon also occurs in heart rate (HR) classical conditioning. For this purpose, a differential...

Summary: | Previous research on electrodermal conditioning suggests that the conditioned diminution of the unconditioned response (UR) has an associative basis. The aim of this experiment was to test whether this phenomenon also occurs in heart rate (HR) classical conditioning. For this purpose, a differential classical conditioning was performed. The conditioned stimuli (CSs) were geometrical shapes (the CS+ was a square and the CS− was a triangle) displayed on a computer screen and a burst of white noise was used as unconditioned stimulus (US). For analysis of the conditioned response (CR) components, an interval between CS+ and US of 8 seconds was used. After the acquisition phase, participants were tested using trials with the US preceded either by a CS+, a CS−, or a neutral stimulus (a circle). The results showed conditioned diminution of the UR and suggest that the second heart rate deceleration component (D2) is responsible for the occurrence of this phenomenon. Investigaciones previas en condicionamiento electrodérmico indican que la disminución condicionada de la respuesta incondicionada (RI) posee una base asociativa. El objetivo de este experimento fue estudiar si este fenómeno ocurre también en el condicionamiento clásico de la tasa cardíaca (TC). Para ello se llevó a cabo un condicionamiento clásico diferencial. Los estímulos condicionados (ECs) eran figuras geométricas (el EC+ era un cuadrado y el EC− un triángulo) mostradas en la pantalla de un ordenador y como estímulo incondicionado (EI) se utilizó una explosión de ruido blanco. Para permitir el análisis de los componentes de la respuesta condicionada (RC) se estableció un intervalo entre el EC+ y el EI de 8 segundos. Tras la fase de adquisición, los sujetos pasaron a la fase de prueba en la que se presentaban cinco ensayos en los que el EI era precedido por un EC+, un EC− o un estímulo neutro (un círculo). Los resultados mostraron disminución condicionada de la RI y sugieren que este fenómeno se debe al componente de deceleración secundaria de la tasa cardíaca (D2). |
