How does the brain process different types of jokes?

What is the primary difference between the comprehension and elaboration phases of humor processing?

The comprehension phase involves detecting and resolving semantic incongruity, while the subsequent elaboration phase is when the humor is appreciated and the emotion of mirth results.

How does the General Theory of Verbal Humor (GTVH) conceptualize the detection and resolution of joke incongruities?

Detection is represented as the awareness of a script opposition (a problem interpreting the text using the initial non-humorous script), and resolution occurs when the reader calls up a second, humorous script to restore coherence.

What is the function of a 'logical mechanism' according to the General Theory of Verbal Humor (GTVH)?

A logical mechanism is the cognitive rule or process (such as role exchange, analogy, or juxtaposition) that connects the joke components in the humorous script, enabling the resolution of the incongruity.
