36
Q

What is biopsychology

A

Biopsychology is the study of the biology of cognition and behaviour. It’s a diverse field incorporating multiple disciplines such as neuropharmacology, neuroanatomy, neurophysiology, neurogenetics, cognitive neuroscience, behavioural neuroscience, neurology, and psychiatry.

Example: Studying how certain neural activity patterns in the brain can generate specific behaviours or cognitive processes, and how experiences can alter these neural patterns.

37
Q

“The brain drives human behaviour and emotion.” In general, would ancient Egyptians and ancient Greeks agree with this statement?

A

Ancient Egyptians would likely disagree, as they discarded the brain during mummification, suggesting they didn’t view it as important for behaviour or emotion. Ancient Greeks, like Aristotle, would also likely disagree, as they believed mental capacities stemmed from the heart, not the brain.

38
Q

“Thoughts have a physical basis – they stem from patterns of neural activity in the brain.” Would a materialist agree with this statement?

A

A materialist would agree that thoughts stem from patterns of neural activity in the brain.

39
Q

“Thoughts have a physical basis – they stem from patterns of neural activity in the brain.” Would Déscartes agree with this statement?

A

Descartes might partially agree but would likely argue for a dualist perspective, suggesting the mind (or soul) interacts with the brain but is separate from it. He proposed the pineal gland as a site of mind-body integration.

40
Q

List three ways to alter behaviour via altering neural activity.

A
  1. Disease: e.g., Parkinson’s disease altering motor behaviour
  2. Drugs: e.g., antidepressants altering mood and behaviour
  3. Electrical stimulation: e.g., deep brain stimulation for treating certain neurological disorders
41
Q

According to John Watson, what is the most important determinant of human behaviour?

A

Watson believed that individual experience (nurture) was the most important determinant of human behaviour.

42
Q

_____ ______ believed that individual experience (nurture) was the most important determinant of human behaviour.

A

John Watson

43
Q

Watson believed that individual experience (nurture) was the most important determinant of human behaviour.

Think about the implications of this for modern society, e.g., should the government fund early childhood education?

A

This perspective would support government funding for early childhood education, as it suggests that early experiences significantly shape future behaviour and capabilities.

44
Q

What did Tyron et al.’s experiments with rats show with regards to heredity and learning?

A

Tyron’s experiments showed that maze performance in rats could be selectively bred, suggesting a genetic component to learning ability.

45
Q

_______’s experiments showed that maze performance in rats could be selectively bred, suggesting a genetic component to learning ability.

A

Tyron’s

46
Q

Tyron’s experiments showed that maze performance in rats could be selectively bred, suggesting a genetic component to learning ability.

What did subsequent experiments suggest might be confounds?

A

Subsequent experiments (e.g., Cooper and Zubek, 1958) showed that environmental factors could override these genetic predispositions, suggesting complex interactions between genetics and environment.

47
Q

Define neuroplasticity

A

The ability of the nervous system to change and remodel in response to experiences.

48
Q

Define epigenetics

A

The study of how certain factors influence gene expression without changing the gene sequence.

49
Q

Describe how neuroplasticity and epigenetics mediate the reciprocal relationship between brain structure/function and behaviour.

A

Neuroplasticity: The ability of the nervous system to change and remodel in response to experiences.

Epigenetics: The study of how certain factors influence gene expression without changing the gene sequence.

Both mediate the reciprocal relationship between brain and behaviour by allowing experiences and behaviours to alter neural structures and gene expression, which in turn can influence future behaviours.

50

What is Paul MacLean’s “Triune Brain Model”?

A

The model suggests three evolutionary layers of the brain: reptilian (brainstem, basal ganglia), paleomammalian (limbic system), and neomammalian (cortex).

A

54
Q

Paul MacLean’s “Triune Brain Model” suggests three evolutionary layers of the brain: reptilian (brainstem, basal ganglia), paleomammalian (limbic system), and neomammalian (cortex).

Provide two arguments that suggest this model is overly simplified.

A
  1. Reptiles do have some cortical and limbic structures, not just a “reptilian brain”
  2. Non-primate mammals have a cortex, not just a “paleomammalian brain”

56
Q

What are the meninges?

A

Meninges are protective layers (dura mater, arachnoid, pia mater) surrounding the brain.

They protect the brain from physical damage and help maintain the tightly constrained skull-meninges-brain space relationship.

57
Q

Meninges are protective layers (____ mater, _________, ___ mater) surrounding the brain. They protect the brain from physical damage and help maintain the tightly constrained skull-meninges-brain space relationship.

A

Meninges are protective layers (dura mater, arachnoid, pia mater) surrounding the brain. They protect the brain from physical damage and help maintain the tightly constrained skull-meninges-brain space relationship.

58
Q

What is “CSF”?

A

CSF is a fluid that fills the ventricles and surrounds the brain and spinal cord.

It provides internal protection (shock absorption) and facilitates nutrient exchange between CSF and brain tissue.

59
Q

What is the blood-brain barrier?

A

The blood-brain barrier is a selective barrier that controls the entry and exit of molecules between the blood and the brain.

It protects the brain from potentially harmful substances while allowing necessary nutrients to pass through.
