Discrimination in Fear-Potentiated Startle Conditioning in Humans
In a fear-potentiated startle experiment, participants were trained in a discrimination task where image A was paired with an electrical pulse, while another image, B, presented itself (i.e., A+ B-). In a test, the startle response, measured as an eyeblink, was evaluated by presenting an air-puff or...

| description | In a fear-potentiated startle experiment, participants were trained in a discrimination task where image A was paired with an electrical pulse, while another image, B, presented itself (i.e., A+ B-). In a test, the startle response, measured as an eyeblink, was evaluated by presenting an air-puff or white noise in the presence or absence of images A and B. The results show a greater eyeblink to the air-puff in the presence of A than in the presence of B, and in the absence of any stimulus, only in those participants who perceived the electrical pulse as highly painful. In conclusion, these findings suggest that conditioned fear is linearly related to the intensity of the electrical pulse.

En un experimento de sobresalto potenciado por el miedo, los participantes fueron entrenados en una tarea de discriminación donde una imagen A se emparejó con un pulso eléctrico, mientras que otra imagen, B, se presentó por sí sola (i.e., A+ B-). En una prueba, la respuesta de sobresalto, medida como parpadeo, fue evaluada al presentar un soplo de aire o un ruido blanco en presencia o ausencia de las imágenes A y B. Los resultados muestran un mayor parpadeo al soplo de aire en presencia de A que en presencia de B, y en ausencia de cualquier estímulo, solo en aquellos participantes que percibieron el pulso eléctrico como altamente doloroso. En conclusión, estos hallazgos sugieren que el miedo condicionado se relaciona linealmente con la intensidad del pulso eléctrico.
