In cognitive psychology, what does a mental set imply about an individual's problem-solving ability?

A mental set refers to a tendency to approach problems in a particular way based on past experiences, even if that approach is not effective for solving the current problem. This habitual reliance on previous solutions can limit an individual's ability to find new or more effective solutions, as they may become "stuck" in their established ways of thinking. Instead of exploring creative or alternative strategies, someone with a strong mental set may overlook better options that might be available for the given situation.

In this context, the other choices highlight qualities such as creativity or flexibility in thinking, which are not characteristics associated with a mental set. Instead of encouraging innovative approaches, a mental set tends to focus narrowly on familiar methods, potentially leading to ineffective problem-solving.
