Summary
Mental preparation for insight problem solving involves specific brain activity. Successful preparation, using Chinese logogriphs, showed heightened activity in frontal, temporal, and cerebellar regions.
Area of Science:
- Cognitive Neuroscience
- Neuroimaging
Background:
- Mental preparation is known to aid insight problem solving.
- Specific brain regions (medial frontal and temporal) are implicated in this preparation.
Purpose of the Study:
- To investigate neural activity during mental preparation.
- To determine if this activity predicts successful insight problem solving using Chinese logogriphs.
Main Methods:
- Developed a task using Chinese logogriphs (riddles).
- Measured blood oxygenation level-dependent (BOLD) fMRI contrasts between successful and unsuccessful mental preparation.
Main Results:
- Heightened brain activity observed during successful mental preparation.
- Key areas included left middle/medial frontal gyrus, left middle/superior temporal gyrus, right cerebellum, bilateral claustrum, and left postcentral gyrus.
Conclusions:
- Neural activity during mental preparation is associated with successful insight problem solving.
- Identified specific brain regions crucial for effective preparation in cognitive tasks.

01:21Cognitive Learning
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

01:29Problem-Solving
Effective problem-solving consists of two steps: 1. identifying the problem and 2. selecting the appropriate problem-solving strategy (i.e., a plan of action used to find a solution). Humans use four problem-solving strategies:
01:37Reason and Intuition
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...
