Shifting the criterion to increase the number of hits will also increase the number of false alarms. This is because a lower criterion will make it more likely that the participant will respond "yes" to weaker stimuli, but also to stimuli that are not actually present, leading to more false alarms. Misses and time-outs (where the participant does not respond within a certain time frame) are not likely to be affected by the criterion shift. Correct rejections may be affected depending on the specifics of the experiment, but generally changing the criterion will not have a major impact on correct rejection rates.
