Evolution and genetics

Question 1

What was the old assumption about human psychology?

Answer 1

It was believed that aspects like self-awareness, memory, and emotions were too complex to arise from the physical brain, leading to a dualism view of mind and body as separate.

Question 2

What evidence challenges the dualism view of psychology and physiology?

Answer 2

Brain damage or stimulation can alter complex psychological functions, demonstrating that self-awareness and other mental processes depend on brain activity.

Question 3

What is asomatognosia?

Answer 3

A condition where a patient loses awareness of part of their body, often the left side, typically caused by damage to the right frontal and parietal lobes.

Question 4

How do nonhuman animals contribute to the understanding of the physiological-psychological connection?

Answer 4

Certain primates exhibit complex problem-solving abilities and self-awareness, suggesting that these traits are not exclusive to humans.

Question 5

What is the conclusion regarding psychological processes and biological mechanisms?

Answer 5

Psychological processes are not separate from physiological ones; they are deeply interconnected and emerge from biological mechanisms.

Question 6

What is the traditional view of the nature-nurture dichotomy?

Answer 6

It posits that behavior is shaped either by genetics (nature) or by environment/learning (nurture).

Question 7

What is a significant flaw in the nature-nurture dichotomy?

Answer 7

Genes and environment are not independent; they continuously interact to shape behavior and development.

Question 8

What do maze-bright and maze-dull rat studies illustrate about genetics and environment?

Answer 8

These studies show that genetic differences interact with enriched or deprived environments, indicating that intelligence and behavior cannot be explained by genetics or environment alone.

Question 9

What do modern biopsychologists believe about behavior?

Answer 9

Behavior results from interactions among genetic endowment, experience, and perception of the current situation.

Question 10

How does evolution influence behavior according to biopsychologists?

Answer 10

Evolution shapes the gene pool of a species, providing the genetic foundation for individual development.

Question 11

What role does experience play in behavior according to biopsychology?

Answer 11

Life experiences influence how genes are expressed, affecting brain development and behavior.

Question 12

What is the significance of current neural activity in behavior?

Answer 12

Current neural activity interprets present circumstances, leading to behavior that arises from how one perceives and responds to the situation.

Question 13

What is the step-by-step model of behavior development?

Answer 13

Evolution influences behavior-influencing genes, individual genes initiate neural development, experiences modify gene expression, and behavior arises from neural activity and perception.

Question 14

How does the success of behavior influence genetic transmission?

Answer 14

The success of behavior affects reproductive success, influencing which genes are passed to future generations.
