Q

Explain overeliance on anecdotes..

A

An anecdote is basically a story about an individual, hard to verify, very hard to generalize, fails to inform us about cause and effect relationships, includes bias

Q

What’s talk of “proof” instead of “evidence”

Science will either support or reject ideas, in science we avoid using “prove”

Q

What are Sensory Receptors?

A

It’s a specialized cell responsible for converting external stimuli into neural activity for a specific system.
- Specialized cells in the back of the eye transduce light
- Specialized cells inside thew transfuse airborne odorant’s

Q

What is the role of the cochlea?

A

Cochlea (‘snail’) converts vibration into neural activity - where
transduction happens

Cochlea contains:
* The origin of corti: tissue containing hair cells

Basilar membrane : membrane supporting the organ of corti & hair cells in the cochlea

Q

What is Stage 1 of sleep? How does brain activity slow down?

A

It’s considered a “light” stage of sleep, and it happens as the brain activity slows down producing THETA waves

*Brain activity is slows when in an
1. BETA - awake and alert stage
2. ALPHA - awake and in a relaxed state
3. GAMMA - awake/concentrating and problem solving

Q

Stage 2, What is it? What happens to the heart rate and muscles?

A

Brain activity slows down even more than before

An EGG would show
1. Sleep Spindles - sudden intense bursts of electrical activity
2. K - Complexes - occasional rising and falling brain waves
*Appear ONLY during sleep

The heart rate and body temperature decreases and muscles relax more…

Q

Stage 3, What is it? and why Is it one of the more important states??

A

In order to have well rested sleep, you need to go through stages 3 and 4, kinda like deep sleep.

*It is Delta waves, for children 40% of their sleep is in deep sleep, however for adults it’s like 1/4 which is like 25%

Q

What Happens after deep sleep?

A

We return to stage 2 and then move onto stage 5 (REM) which is 20-25% of out sleep.

In this stage the brain is….
*most active
*body is inactive…known paradoxical sleep

This is when dreaming occurs, REM sleep is longer when entered early morning rather then closer to when we first fall asleep….stages 1-4 ARE NOT REM!!!!!

Q

What is classical conditioning?

A

Form of learning in which one responds to a previously neutral stimulus that has been paired with another stimulus which elicits an automatic response

Q

What is conditioning? give an example of learning through condition..

A

Conditioning is forming associations between stimuli, making connections between two things, an example would be a child makes a connection between his moms voice and sees her face, so then when she speaks from the other room he can recognize her.

Q

What do we have to do in order to develop to respond?

A

In order to develop a response, we have to pair the neutral stimuli wit another stimulus to get that response

Q

Explain Conditioned Stimulus (CS)

A

Initially neutral stimulus that comes to elicit a response due to association with an UCS (i.e., metronome)

22
Q

Conditioned Response (CR)

A

Response previously associated with a non neutral stimulus that is elicited by a (previously) neutral stimulus through conditioning (i.e., salivation)

23
Q

Name 3 phases of classical conditioning

A

Acquisition, extinction, and spontaneous recovery

24
Q

Explain higher order conditioning

A

When one develops a CR to a CS due to its association with another CS…
- Whereas in classical conditioning - one develops a CR to a CS due to its association with and UCS

25
Q

What is higher order conditioning?

A

it’s when each progressive level results in weaker conditioning…

2nd-order conditioning tends to be weaker than classical conditioning
3rd-order conditioning tends to be weaker than 2nd-order conditioning
4th-order conditioning tends to be weaker than 3rd-order conditioning

26
Q

Explain classical conditioning…

A

Learning phase during which a conditional response is established

27
Q

Explain the different between classical conditioning and operant conditioning

A

In classical conditioning the reward is independent of the response, however it’s the opposite for operant conditioning, where the reward is dependant on the response. Operant conditioning is where the behaviour is voluntary, in classical behaviour is pulled out automatically as a response.

28
Q

Explain the difference between reinforcement and punishment…

A

Reinforcement is when any consequence that makes a behaviour more likely to occur (strengthens the probability of the behaviour), however with punishment any consequence that makes a behaviour less likely to occur (weakens the probability of a behaviour).

29
Q

Which one works better in the long run? reinforcement or punishment?

A

Reinforcement works better in the long run than punishment. Because punishment
tells people what not to do rather than teaching what to do instead, and it can create anxiety which interferes with future learning.

30
Q

What are the 3 logical fallacies we covered in lecture 1?

A
  1. Emotional reasoning fallacy
  2. Bandwagon fallacy
  3. Not me fallacy
31
Q
  1. Emotional reasoning fallacy
A

Just cause it makes us feel some way doesn’t mean its wrong.

32
Q
  1. Bandwagon fallacy
A

Just because multiple people believe it does not mean it’s true..

33
Q
  1. Not me fallacy
A

Can get us into trouble, bias blindspot - unaware of our own biases but we’re aware of other peoples biases

34
Q

Science VS Pseudoscience

A

Pseudoscience can be more believable therefore making it more dangerous…very misguiding and time consuming.. can be very dangerous

35
Q

What are the 3 major theoretical viewpoints

A
  1. Behaviourism
  2. Cognitivism
  3. Psychoanalysis
36
Q

Who opened the first lab for psychology?

A

William Wundt, gave psych a scientific view

37
Q

Explain Behaviourism

A

Uncovering the general laws of learning by studying observable behaviour..

**John B Watson - why do people think the way they do

BF Skinner - people can change knowing the consequences that follow them

  • Performed Watson and Little Albert, which was unethical
38
Q

Explain Cognitivism

A

Jean Piaget…how each person reward is different and how people evaluate things

Cognitive neuroscience and affective neuroscience

Peaking inside the black box - by aiming to study psychology objectively

39
Q

Explain Psychoanalysis

A

Sigmund Frued (aka mommy issues)

Unconscious Mind- memories outside of our conscious which influences our behaviour (outside of our awareness)

Freudian slips..slip of the tongue, there is a reason behind everything we do and some things we say by accident which we might’ve meant, symbolic meanings

40
Q

Free-will determinism debate

A

BF skinner..to what extent are our behaviours freely selected than caused by factors outside of our control, some believe free will is on illusions

40
Q

The Nature and Nature Debate

A

By John Locke: The mind = tabula rasa at birth, how genes and environment play important role in behaviour

41
Q

Two types of thinking, what are they?

A

Type 1 - Intuitive thinking: quick and reflexive doesn’t require much thinking and effort

Type 2 - Analytical thinking: slow and reflective

42
Q

Evaluating
Measures - Reliability

A

Reliability is the consistency of measurement, two types, test-retest reliability and inter-rater reliability

43
Q

Validity

A

The extent to which a measure assesses what it claims to measure

44
Q

The Cerebral Cortex

A

The outermost layer of the brain, the corpus callosum carries the large bundle of fibers connecting the 2
cerebral hemispheres

45
Q

Lateralization

A

cognitive functions that rely more one one hemisphere then the other

left hemp controls right side

right hemp control left

46
Q

What are the 4 lobes

A
  1. Frontal lobe
  2. Parietal lobe
  3. Temporal
  4. Occipital lobe
47
Q

Frontal Lobe

A

Performs executive that coordinates other brain areas

(motor planning, language, decision making)

Central sulcus → sulcus that separates the frontal lobe from the parietal lobe

  • Motor cortex
48
Q

Parietal Libe

A
  • Touch & perception
  • Spatial perception
    -Hemispatial neglect
49
Q

Temporal Lobe

A
  • Hearing, understanding language & memory
  • Auditory cortex
  • Fusiform face area
50
Q

Occipital Lobe

A

Contains the the primary and association visual cortex
