Q

What is Structuralism?

A
  • divides the mind up into segmented structures and described these
  • established psychology as a separate discipline
  • psychology is the scientific study of the conscious experience
  • investigated vision, touch, hearing, taste, attention and emotion

Q

What is Functionalism?

A

consciousness cannot be broken into its individual components
consciousness consists of a flow of thoughts, stream of consciousness in interaction with environment
- patterns of development during childhood
- behavioural differences between males and females

Q

Psychodynamic - Who came up with it and what is it? How is it tested?

A

Sigmund Freud - focuses on the unconscious mind. The ice burg metaphor. It is tested by case studies of patients, reflection one’s owns inner thoughts - dreams, fantasies, slips of tongue

Q

Behaviourism - Who came up with it and what is it? How is it tested?

A

B. F Skinner + James Watson -behaviour is learned by its environment. Only to do with “nurture”, stimulus from the environment went into the black box and a response (the behaviour) came out. It is tested by experimentation on humans and animals - classical conditioning and operant conditioning

Q

Humanistic - Who came up with it and what is it? How is it tested?

Q

Cognitive - Who came up with it and what is it? How is it tested?

A

Piaget - cognitive development. Miller - Memory.
Chomsky - Language.
Newll, Shaw and Simon - Problem Solving
Cognitive process oncides memory, reasonsing, decision making, thoughts etc. The brain is like a computer. It is tested by Human experimentation and cognitive neuroscience (brain damage and effect on cognition)

Evolutionary - Who came up with it and what is it? How is it tested?

A

Q

What is the Scientific Approach

A

Assumes events are governed by some lawful order. Psychology research seeks to identify the laws, principles, or consistencies governing behaviour

Q

Goals of the Scientific Approach

A

Description - Understand what we have and summarize data in a way that makes the events and relationship between them easily understandable
Prediction - Being able to predict based on previous research
Understanding - why is something happening and What is the underlying factor?

Q

Basic Concepts in emperical Research

A

Population:
- the group of people that a researcher is interested in
- representative sample
- typically study samples
Generalisability:
- Internal Sample (procedures are flawed or not)
- External Validity (does it resemble what would happen in the real world?)

Q

Problems with stats

A 
Extraneous variables (stuff other than the IV that might influence the DV - age, gender?)
Confounding (when 2 variables are linked together so it makes it difficult what actually impacted the DV)
Random Assignment of Participants

25
Advantages of experimental research
cause-effect relationships
26
Limitations of experimental research
some experiments are artificial | - manipulations of some variables is not ethical, difficult or impossible
27
descriptive research + disadvantages
case studies, naturalistic observation, survey research. Good generalizability + observation can alter behaviour and cannot establish the cause of behaviour
28
survey technique + disadvantages
questionnaires and interviews + sampling issues and ppl may not respond accurately
29
correlational research
``` used when variables cannot be manipulated correlation coefficient (r) indicates strength. CORRELATION DOES NOT IMPLY CAUSATION ```
30
CNS
Central Nervous System (brain, spinal cord)
31
PNS
Peripheral Nervous System
32
3 types of Neurons
Sensory - Afferent Motor - Efferent Interneurons - nerve cells that connect neurons to other neurons
33
Anatomy of a Neuron
``` Dendrites Soma (Cell Body) Axon Myelin Sheath Axon Terminal Synapse Pre Synaptic Neuron Post Synaptic Neuron Synaptic Vesicles Synaptic Cleft Neurotransmitters Node of Ranvier ```
34
Steps to Action Potential
1. The neuron is at rest, there are more sodium ions outside the cell compared to the potassium ions inside 2. Sodium-Potassium pumps out 3 sodium ions and in 2 potassium ions to maintain the resting potential 3. A stimulus causes the cell to depolarise past the threshold of excitement, causing sodium ions channel to open 4. Sodium ions rush in, cell depolarises 5. Action Potential is triggered and travels down the axon as the membrane of the axon depolarizes and repolarizes at each spot on the axon 6. The action potential causes the release of neurotransmitters into the synaptic cleft, where they bind with receptors on the postsynaptic neuron. 7. If a threshold is reached, the post-synaptic neuron is depolarized
35
Acetylcholine
- excitatory neurotransmitter - triggers muscle contraction involved in wakefulness, anger, thirst, aggression ALZHEIMER'S DISEASE
36
Dopamine
-controlling movement - moderates mood positive reinforcement PARKINSON'S DISEASE (rigidity)
37
GABA
- inhibitory neurotransmitter - motor control, vision - regulates anxiety USED TO TREAT EPILEPSY AND HUNTINGTON'S DISEASE
38
Glutamate
- major excitatory neurotransmitter - associated with learning and memory ALZHEIMER'S DISEASE (memory impairment)
39
Serotonin
-various functions like regulating body temp, sleep, mood, appetite, pain SUICIDE, DEPRESSION, IMPULSIVE BEHAVIOUR
40
Norepinephrine (noradrenalin)
important for attentiveness - emotions - sleeping - dreaming - learning Released as a hormone in the blood and causes heart rate to increase MANIC DEPRESSION
41
Invasive Methods of Studying Brain Structure
Autopsies and brain dissection | Neural Staining
42
Non-Invasive Methods of Studying Brain Structure
``` MRI -excellent spatial resolution -lesions -strokes DTI -coloured shit ```
43
Non-Invasive Methods of Studying Brain Functions
EEG -excellent temporal resolution (milliseconds) fMRI -poor temporal resolution (seconds) MEG -similar to EEG -uses magnetic rather than electrical signals
44
Invasive Methods of Studying Brain Structure
Lesions Single cell recording Possibly TMS (transcranial magnetic stimulation) - sends a magnetic pulse through the scalp into the brain
45
Nervous System
PNS and CNS
46
PNS
Somatic (conveys sensory information to the central nervous system) AFFERENT AND EFFERENT and Autonomic (serves basic life functions like breathing)
47
Autonomic Nervous System
Sympathetic (readies the body for a threat) and Parasympathetic (clams the body down)
48
CNS
Spinal Cord (receives sensory input - sends info to the brain) and Brain (directs psychological activity - processes information)
49
Left Hemisphere
Speech, Reading, Language, Sounds, Complex Movement
50
Right Hemisphere
Emotional Content, Direction, Distance, Nonverbal Memory, Face and Patterns, Left Visual Field
51
Corpus Collosum
Communicates between the two hemispheres
52
Split Brain Patients
Left Hemisphere dominant for language | Right Hemisphere can draw the object
53
Occipital Lobe
Processes visual information | Anton Banbinski - sufferers are blind but they are adamant that they can see
54
Parietal Lobe
Processes touch Egocentric space -neglect happens when there is damage to the right parietal lobe (ppl do not pay attention to the left side of their world) Visual attention and information
55
Temporal Lobe
Processes auditory information Speech and Language Symptoms of damage: impaired long term memory, language comprehension, altered personality
56
Frontal Lobe
High order tasks like social skills and abstract thinking
57
Prefrontal Cortex
Cognitive control: orchestrate thought and actions in accordance with internal goals
58
Broca's Aphasia
Left Frontal Lobe | Speech Production: difficulty putting together grammatical sentences
59
Wernicke's Aphasia
Left Temporal Lobe | Language Comprehension: word salad
60
Hindbrain
Cerebellum, Pons, Medulla and Reticular Formation
61
Cerebellum
important for balance and coordination
62
Medulla
Unconscious but vital bodily functions like breathing and blood flow
63
Reticular formation
involved in consciousness and arousal
64
Midbrain
Tectum and Tegmentum
65
Tectum
Visual and Auditory stimuli
66
Tegmentum
movement and arousal - learning consequences
67
Forebrain
Thalamus, Hypothalamus, subcortical structures of the cerebrum (limbic system), cerebral cortex (4 lobes)
68
Thalamus
receives and sends all sensory information to the relevant areas of the brain
69
Hypothalamus
helps regulate behaviour like eating, sleeping, sexual activity and emotional experience
70
Limbic System
Thalamus, Hippocampus, Amygdala and Mammillary Body
71
Hippocampus
Storage of long term memories
72
Amygdala
processing emotions
