Answer:
. A hungry pigeon is in a Skinner box and is pecking a key for access to food. The first food delivery occurs for the first peck after 1 minute has elapsed. The second occurs for the first peck after 3 minutes has elapsed. The third food delivery occurs for the first peck after 2 minutes has elapsed. All other peck's went unrewarded, but the pigeon did not receive access to food unless it pecked the key. The pigeon is most likely on a <u>VI(Variable Interval)</u> schedule of reinforcement.
Explanation:
Variable-interval (VI) schedule :
A partial reinforcement that rewards the first correct response after an unpredictable amount of time. It produces slow and steady responses with little or no post-reinforcement pause (produces an overall low consistent rate of responding).
For example: I get a pellet of food on average every 5 minutes when I press the bar.
Hence, as in the given scenario, . A hungry pigeon is in a Skinner box and is pecking a key for access to food. The first food delivery occurs for the first peck after 1 minute has elapsed. The second occurs for the first peck after 3 minutes has elapsed. The third food delivery occurs for the first peck after 2 minutes has elapsed. All other peck's went unrewarded, but the pigeon did not receive access to food unless it pecked the key. The pigeon is most likely on a <u>VI(Variable Interval)</u> schedule of reinforcement.

Answer:
over 70 percent accurate for mild neurocognitive impairment, and over 80 percent accurate for major neurocognitive impairment
Explanation:
Lisa Mosconi and her associates in a research titled "Hippocampal hypometabolism predicts cognitive decline from normal aging" reported that over 70 percent of participants with low hippocampus activity developed mild neurocognitive impairment, and that their predictions was over 80 percent accurate for major neurocognitive impairment.
