Abstract:
Globally, approximately 90% of individuals are right-handed, while the remaining 10% are left-handed. Handedness is associated with functional lateralization of cerebral dominance, and may also be associated with various types of psychological characteristics. Unfortunately, neuromyths of left handedness have become deeply embedded in public consciousness due to misleading studies. In neuroscience research, it is common for left-handed individuals to be excluded from study cohorts in an attempt to increase data uniformity. Left-handed participants represent a substantial portion of the population and their inclusion of left-handed participants can be informative in studies of cerebral asymmetry. We should aim to construct a society that allows people with diverse characteristics, such as left-handed individuals live without discomfort or stress.

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.
Tolman introduced the idea that behavior is influenced by...
