The Rorschach test is gaining new respect as a diagnostic tool because it takes only one hour to expose behavior and thought processes that may be unlikely to emerge in other procedures or weeks of ordinary interviewing.
that may be unlikely to emerge in other procedures or weeks of ordinary interviewing
whose emergence is unlikely in other procedures or weeks of ordinary interviews
that might not emerge in other procedures or in weeks of ordinary interviews
that may not emerge under other procedures or weeks of ordinary interviews
likely not to emerge during weeks of ordinary interviewing or in other procedures
There's a difference in meaning between "may not" and "might not." Consider two examples:
1) Tim's daughter may not go to the dance with the boy sporting the tattoo of Barry Manilow on his face.
Here, "may not" means "does not have permission." So, Tim's daughter has been forbidden to go to the dance with a weirdo, and Tim can rest easy.
2) Tim's daughter might not go to the dance with the boy sporting the tattoo of Barry Manilow on his face.
Now, "might not" means there's a possibility that something won't happen. So there's still a real chance that Tim's daughter will be attending the dance with a shady character.
For our GMAT example, it makes sense to write that there's a possibility that behavior and thought processes won't emerge; it doesn't really make sense to write that the behavior and thought processes have been forbidden to emerge. So "might not" is the more logical option.

ll sentence “unlikely to emerge in X or in Y” is parallel and idiomatic
