Final answer:
Climbing a tree primarily involves implicit procedural memory, which is a type of implicit memory that encompasses learned motor skills that become automatic without conscious thought.
Step-by-step explanation:
When you are climbing a tree, the type of memory that you would primarily use is implicit procedural memory. This involves the learned motor skills and actions that have become automatic through practice, such as maintaining balance and knowing where to place your hands and feet without consciously thinking about it. This form of memory is crucial for tasks that require physical coordination and is developed over time through repetition and practice.
Unlike explicit memory, which involves conscious recollection of information and facts, implicit memory works subconsciously. For example, recalling the chemistry material you study for an exam involves explicit memory; it is knowledge you actively try to remember and articulate. In contrast, the improved abilities in bike-riding or tree-climbing exemplify implicit memory; these are tasks that we perform automatically without deliberate thought after the initial learning phase.
