Which of the following is a common feature of blindsight and neglect patients:
Group of answer choices
They fail to respond to primes in the regions of their visual field where they lack conscious awareness
They have no residual awareness in the regions of their visual field where they describe themselves as having conscious awareness
They typically do not initiate movements towards objects in the regions of their visual field where they lack conscious awareness
They typically do not initiate movements towards objects in the regions of their visual field where they lack conscious awareness
The common feature between blindsight and neglect patients is that they typically do not initiate movements towards objects in the regions of their visual field where they lack conscious awareness.
To determine which of the following is a common feature of blindsight and neglect patients, we need to understand the characteristics of both conditions.
Blindsight is a phenomenon where individuals who have visual impairments or damages to their primary visual cortex can still respond to visual stimuli despite having no conscious awareness of them. This means that blindsight patients can react to stimuli even though they are not consciously aware of their existence.
Neglect, on the other hand, refers to a condition where individuals fail to attend or respond to stimuli presented on one side of their visual field, typically after damage to the brain's attention and awareness networks. Neglect patients often ignore or fail to notice information from one side of their visual field due to a lack of conscious awareness and attention.
Now, let's analyze the answer choices to identify the common feature of blindsight and neglect patients:
1. They fail to respond to primes in the regions of their visual field where they lack conscious awareness.
This statement is inconsistent with the characteristics of blindsight patients. Blindsight patients can still respond to visual stimuli in regions where they lack conscious awareness, so this choice is not accurate.
2. They have no residual awareness in the regions of their visual field where they describe themselves as having conscious awareness.
This statement doesn't describe either blindsight or neglect patients accurately. Blindsight patients have no conscious awareness, while neglect patients have a lack of awareness on one side of their visual field. So this choice is not correct.
3. They typically do not initiate movements towards objects in the regions of their visual field where they lack conscious awareness.
This choice accurately describes a common feature of both blindsight and neglect patients. Blindsight patients do not consciously perceive the stimuli but can still initiate movements towards them, and neglect patients also fail to initiate movements towards objects in the neglected region of their visual field.
Therefore, the correct answer is:
- They typically do not initiate movements towards objects in the regions of their visual field where they lack conscious awareness.
