520.3.#.a: In two experiments of fear-potentiated startle, human participants were trained in a discrimination task, in which a stimulus a was paired with a wrist shock, while another stimulus, b, was not (a+b-). in a test, participants were assessed for startle by presenting an air-puff either alone or in the presence of the trained stimulus. in experiment 1, evidence of discriminative learning was found in the form of a reliably greater startle to the air-puff in the presence of a than in the presence of b, and in the absence of any cue. in experiment 2, after a+b- training (counterbalanced visual and vibrotactile cues), cues a and b were compounded with novel auditory cues x and y and reinforced (ax+by+), which is the standard design for cue-competition. in test, there was evidence of cue competition only in those participants in which a and b were the visual and vibrotactile cues, respectively. in this subgroup, responding in the presence of the redundant cue x was reliably lower than in the presence of y, and not different from responding to the air-puff alone, indicating that x was blocked by a. we speculate that the absence of such an effect in the subgroup in which a was vibrotactile and b was visual might be due to some unexpected generalization between vibrotactile and auditory cues.

Resumen
In two experiments of fear-potentiated startle, human participants were trained in a discrimination task, in which a stimulus a was paired with a wrist shock, while another stimulus, b, was not (a+b-). in a test, participants were assessed for startle by presenting an air-puff either alone or in the presence of the trained stimulus. in experiment 1, evidence of discriminative learning was found in the form of a reliably greater startle to the air-puff in the presence of a than in the presence of b, and in the absence of any cue. in experiment 2, after a+b- training (counterbalanced visual and vibrotactile cues), cues a and b were compounded with novel auditory cues x and y and reinforced (ax+by+), which is the standard design for cue-competition. in test, there was evidence of cue competition only in those participants in which a and b were the visual and vibrotactile cues, respectively. in this subgroup, responding in the presence of the redundant cue x was reliably lower than in the presence of y, and not different from responding to the air-puff alone, indicating that x was blocked by a. we speculate that the absence of such an effect in the subgroup in which a was vibrotactile and b was visual might be due to some unexpected generalization between vibrotactile and auditory cues.
