Q

Mind-body problem

A

The mystery (issue) of how the mind is related to the brain and body.

  • René Descartes proposed that the human body is physical matter and human mind is seperate of thinking matter.
  • Psychologists assume that thinking causes neural activity in the brain.
  • Some studies show that brain activities happen before the activities of the conscious mind.

Q

Consciousness: Four Basic Properties: Transcience

A

Transcience: The tendency for consciousness to change from one “right now” to the next: A constantly changing stream of consciousness since humans can hold only to a limited amount of information at the same time consciously, so when we select more information, some of what is currently there must disappear.
Out focus of attention keeps changing.

Q

Levels of Consciousness: Minimal consciousness

A

Minimal consciousness: A low-level of sensory awareness and responsiveness to it, the mind inputs sensory information and may output behaviour.

The mind registers that sensory information (like a poke), and may respond by a behaviour, but the person may not be aware of having had that experience.

Q

Experience-sampling/ Ecological momentary assessment (EMA)

A

Technique to learn what is one people’s minds by asking them by asking people to report on their conscious experiences at specific times.

Experience-sampling is increasingly being used to study what it is like to be human by focusing on a range of different aspects of conscious experiences. (Ex. Asking when someone feels bored during the day, to understand what activities make people the most bored).

Q

A

A state of consciousness where a purposeless flow of thoughts come to mind.

Q

Ironic process of mental control:

A

Q

Cognitive unconscious

A

A fast, automatic information processor that give rise/ influence’s to a person’s thoughts, feeling and behaviors.

29
Q

Dual-process theories:

System 1

System 2

A

Suggest that humans have 2 different ways of processing information that draw on different neural pathways.

System 1: Unconscious mind, fast, automatic, used for easy tasks.

System 2: Conscious mind, slow, for complex tasks.

System 2 uses information from System 1 to help guide future behavior when there’s something unexpected that happens.

30

A naturally occuring 24 hour cycle of sleep and waking.

35
Q

EGG Pattern During Stages of Sleep: Awake

A

A

An instrument that measures eye movement.

41

A dream’s true (hard to find the correct one, since there are infinite possibilities of a dream’s true meaning) underlying meaning.

53
Q

Activation-synthesis model:

A

Dreams are the brains attempt to make sense of the random neural activity that occurs during sleep. The brain continues interpreting information and its interpretive mechanisms can run free since it doesn’t external sensation to make sense of it.

54

Continuing to use a drug to prevent the physical withdrawals (ex. pain, convulsions).

57

Psychological dependence

A

A strong desire to return to the drug even when physical withdrawal symptons are gone.

An emotional need for a drug after physical withdrawal symptons are gonee.

58
Q

Depressants

A

Substances that reduce the activities of the central nervous system (inhibiting neural transmisson).

Sedative and calming effect.

Can produce physical and psychological dependence.

Ex. Alcohol

59
Q

Alcohol and different resulting behaviours theories: Expectancy theory

A

Alcohol behaviour effects can be produced by people’s expectations of how it will influence them.

60
Q

Alcohol and different resulting behaviours theories: Alcohol myopia

A

Alcohol decreases attention (and judgement) leading people to respond is simple ways to complex situations.

61
Q

Balanced placebo design:

A

The mere belief that one has experienced the actual stimulus, when one hasn’t, causes the behaviour as if the person did experience it.

62
Q

Stimulants:

A

Substances that excites the central nervous system (increases neutrotransmission activities) increasing altertness and energy.

Stimulants increase the levels of dopamine and norepinephrine, thus increasing alterness and energy.

63
Q

Narcotics/ opiates:

A

Highly addicitive drugs that relieve pain and are derived from opium.

64
Q

Hallucinogens:

A

Alters the experience of sensation and perception and often causes visual and auditory hallucinations.

Mildly hallucinogenic.

66
Q

Getaway drug:

A

A drug that increases the chance of using other harmful drugs in the future.

67
Q

A

A social interaction where one person (the hypnotist) makes suggestions that changes the subjective experience of the participant.

68

A

Where someone loses specific memories following hypnotic suggestions to forget.

69
Q

Hypnotic analgesia:

A

The reduction of pain by hypnosis in people who are susceptible to hypnosis.
