Final answer:
Tasks that prompt more self-oriented gestures involve stereognosis and graphesthesia, as they rely on somatosensory feedback without visual input. These gestures help in processing and identifying objects like coins or written symbols on the skin through touch.
Step-by-step explanation:
The type of task that prompts more self-oriented gesture is typically one that requires stereognosis, which is the perception of common objects by manipulation without visual cues. This task involves identifying objects such as coins by their sensory characteristics like size, thickness, or edge type. Another example is graphesthesia, which is the ability to recognize writing on the skin purely through the sensation of touch.
Praxis, on the other hand, is a task that requires performing movements based on verbal instructions, which heavily relies on a patient's procedural memory and involves sensory feedback for correct execution. Tasks that demand such integration of sensory information and motor control are likely to elicit self-oriented gestures that aid in the processing and execution of the task.
Overall, these tasks that engage both sensory perception and procedural memory necessitate a higher level of internal focus and self-oriented gestures to perform the task accurately based on somatosensory feedback.
