dc.description.abstractWe reviewed the literature on the relationship between conditioned stimulus (CS) intensity and conditioned response (CR) strength. Overall, studies indicate that both variables are positively related, however, such a relation has seldom been found in humans, especially when between-subjects designs are used. Moreover, in humans, the effect has only been investigated using auditory CSs in galvanic skin response and eyelid conditioning procedures. By using a videogame task, we assessed the relationship between CS intensity and the CR along two conditioning phases in human participants. In phase 1, participants were trained to respond to a light that signaled an imminent spaceship attack. The light could be bright or dim (between-groups). In phase 2, the alternate stimulus was used. The intensity had no effect on phase 1 but had a small effect in phase 2, after participants had the opportunity to compare both stimulus intensities. An assessment of the shift that occurred between phases showed a slight generalization decrement only in the bright-to-dim group, allowing some room for improvement during phase 2 in that group. The absence of a decrement with the stimulus shift in the dim-to-bright group could be ascribed to the bright stimulus having energizing properties that compensate for the decrement.es
