Q

Watsons’ view

A

Inspired by Pavlov- argued that psych subject matter was more behaviourism. Need to focus on behaviour not what is in the mind. Had problem with introspection as there is no way to verify it

Q

Cognitive dissonance

Example

A

People need to justify behaviour

Can you justify a task for $20 or $1

In experiment of doing useless tasks and then be given either $20 or $1, people who liked the tasks DIDN’T even want the $1, people who rated the tasks as boring justified it by getting $20.

People gave higher ratings when paid less

25
Milgrims experiment and common sense
- a learner who was in on it - teacher who was participate - experimenter who said things to keep teacher going - shocks for wrong answers keep growing in intensity Psychiatrists believed no human would even reach shock levels beyond a certain point. However majority did because they felt pressure from an authority figure. 60% gave deadly shock levels
26
Hindsight bias
I knew it all along
27
Viewpoints of milgram experiments
- some say unethical and damaged reputation of researchers - debriefing after experiment left majority glad they participated and learned that just words could get them to harm or kill others - no negative effects can be proven following experiment on participants
28
Scientific method
An objective systematic approach that combines rationalism and empiricism to correct for biases in observations - objective: not bias to feelings, observations are verifiable by others - rationalism: use logic and reason to draw conclusions - empiricism: use sensory information to check your logic and reasoning
29
Example of syllogism
All crows are black I see a crow Therefore I see a black crow
30
Naïve realism
Our senses can fool us Ex: same length arrows
31
Draw the scientific method, psychology, rationalism, empiricism and ideas shape outline
``` Psychology | V Ideas scientific method ^ | Rationalism. Empiricism ```
32
Goals of psychology
- describe - explain - predict - control - improve quality of life
33
Description in goals of psychology
Focus is on what is directly observable - responses (behaviours and actions) - stimuli (triggers of responses ) Ex: antisocial behaviours- prejudice Eye movements while reading What part of brain lights up when Imagining a scene
34
Explanation in the goals of psychology
What causes the behaviour - permissible to infer inner states or processes (fear) - intervening variable - unseen state or process responsible for the behaviour (connect observable stimuli to measurable responses)
35
Andrea Yates Biological perspective
Killed children in bathtub because they weren’t developing properly Low self esteem Depression Psychosis (severe impairment in thinking and perceiving emotions l responses) - do not believe anything is wrong with them - behaviour genetics: mood disorders and depression in family - neuroscience: neurotransmitter sera ronin reduced in people with depression
36
Behavioural and social cultural context to Andrea Yates
- why was she removed from medication? - why husband not more supportive? - where was extended family? - impregnated with 5th against doctors wishes
37
Complementary perspectives Biopsychosocial
Behaviour and mental prefixes are complex and made up of all these Biological - neuroscience - behaviour genetics - evolutionary Psychological - psychodynamic - behavioural - cognitive Social cultural - others present - culture/ family/ social - peers/ group
38
Prediction in goals of psychology
Statement about how likely an event or relationship will be found
39
Hypothesis
Testable statement that something will happen under specific conditions
40
FAP
Fixed action pattern (instinct) Tina Turkey only provided maternal behaviour when she heard chirping
41
Do humans have FAP
Not really… not in same way as animals Sucking response about it
42
Control in goals of psychology
Ability to control various aspects of behaviour/ experience - start - maintain - stop - change strength/rate of a particular behaviour Ex: can you get someone to smoke and then stop smoking??
43
Improve quality of life in goals of psychology using two types of research
Applied research: -solutions to practical problems Examples: does a third brake light persevere lives?, Does money create happiness? Basic research: -pursuit of knowledge for the sake of knowledge Examples: can robots become conscious?, how smart are animals???
44
Basic research is the _____ for ____
Foundation Applied research Knowledge gained can become solutions to practical problems later on
45
Clever Hans story
Von oster believed horses were just as intelligent as humans if trained to be… So he taught Celver Hans everything and clever Hans could answer any question and even spell out answers… von invited scientists to check out his horse. Pfungst disagreed with theory that Hans was smart instead had a theory that clever Hans was picked up on subtle social cues in the audience. So he tested it by putting blinders on horse and then having no one in audience know the answer and Hans could no longer give correct answers.
46
Facts Theories Hypothesis
Objective statement based on observation Model that explains existing facts and predicts new ones Derives from theory and predicts new facts
47
Circle of scientific inquiry
Never ending Facts-theories-hypothesis- facts- theory- hypothesis Observation-hypothesis-prediction
48
Grid box strategy
Design= E: experimental, C: Correlational, D=descriptive study Data= SR: self report, O: observational Setting= L: Laboratory, F: Field
49
Operational definitions
Statements about the procedures or operations for a study and measurements of results Ex: fear (moving away) Attraction (time spent gazing)
50
Experiment research design
-Most direct way to test a hypothesis Goal: to investigate how dependent variable is effected by independent variable -control all other relevant variables so only IV is working (true experiment) : removes all confounds
51
Extraneous variables
Variables besides the IV that may effect the DV If extraneous variables are controlled to not change you can say the IV caused the DV
52
Types of experiment
Within-subjects -The same participants are exposed to all different levels of IV Ex: Clever Hans Between-subjects -randomly assigned people (maybe in different groups) and exposed to different trials.
53
Correlational study
-can’t say IV caused other variable to change -no manipulated IV’s -simply observe or measure 2 or more variables -establish lawful relationships and make predictions Ex: self esteem and depression NO CAUSE-EFFECT RELATIONSHIP Ex: punishment is harmful to children’s development study where random parents and children were observed.
54
Correlation and causation in example
Was parenting style the cause of children’s behaviour? Was children’s behaviour the cause of parenting style? Was family status, health, neighbourhood or income the cause of parenting style and or child’s behaviour?
55
Illusory correlation
Confirmation bias: People tend to confirm evidence for something they believe to be true Ex: infertile parents are more likely to conceive after adopting
56
To have an appropriate correlation you must evaluate
Confirming and disconfirming evidence otherwise it leads to illusory correlation
57
Random events
People tend to think extraordinary events are proof for extraordinary concepts. However it is really about chance. Random sequences are all equally as likely HTHTHT likely as HHHHHH
58
Gamblers fallacy
People tend to link between past events and future events when the two are really unrelated. Ex: if heads 5 times in a row it’s not more likely to be tails on the next toss
59
In perception of order Humans tend to
Seek relationships, meaning and explanations yet discount chance as an explanation Leads to bias
60
Descriptive study
- Careful statement about how things are - May or may not involve numbers - case studies, surgery’s, naturalistic observations - useful for developing insights into relationships - no cause-effect correlation Ex: survey of how many people have disease in Winnipeg. Looking at mating behaviour in mallards
61
Settings
Lab: careful control but artificial Can lead to subject reactivity (more on guard in a lab) Field: natural, but little control
62
Data
Self report: introspection; can lead to false results as people are not always honest. -surgery’s, interviews, and rating scales Observation: tests, devices and behaviour observations - IQ, reading skills, reaction time - observe deuces and describe behaviour
63
Data can come up with _______ to come up with new ideas
Empirical evidence
64
Types of Statistics
1. Descriptive statistics-organize/summarizing data | 2. Inferential statistics-draw conclusions about data
65
Properties of descriptive statistics
Shape (symmetry and modality) Center Spread
66
Measures of central tendency
Mode-most frequently occurring score Median-middle number Mean -average number
67
Symmetrical distribution
Mode=median=mean
68
Positively skewed spread
Median< mean Mode and median are close
69
Range
The difference between the highest and lowest scores in a distribution
70
Standard deviation
A computer measure of how much scores vary around the mean.
71
Empirical rule
68% within 1 SD 95% within 2 SD 99.7% within 3 SD
72
Scatterplots
Graph consisting of points derived from two variables - direction of relationship +,-, none - strength of relationship strong, weak
73
Correlation coefficient What’s a perfect positive relationship or perfect negative relationship
Number that describes the direction and strength relationship of a scatterplots Perfect positive relationship =1.00 -1.00
74
Population Sample
Large group Smaller subset of population
75
Statistical significance
Are our findings a fluke? P-value measures chance influences. When p-value is small it is very unlikely the findings are just a fluke. 5% or less is small p-value P<5% = statistically significant and not by chance P<0.05
76
Effect size matters
Demonstrate big effects not little to be practical
77
What did ancient Greeks think the brain did and how did they discover info about the brain
Blood cooler Noticed brain injuries changed people
78
Nervous system Endocrine system
speedy electrochemical (nerve cells) Slow hormonal (blood stream used)
79
When we sleep what gland releases melatonin to slow down bodily functions
Pineal gland
80
CNS PNS
Central nervous system -brain and spinal cord Peripheral nervous system - connects CNS to rest of the body - connects all sensory systems to brain and allows brain to send messages out to the body to control glands and muscles
81
Automatic and somatic nervous system
Automatic - unconscious control of organs and glands - sweating, breathing Somatic (conscious) - controls voluntary movement of skeletal muscles - writing, reading, running
82
Sympathetic and parasympathetic examples
Sympathetic - dialates pupils - accelerate heartbeat - inhibits digestion - stimulates glucose release in liver - stimulates ejaculation - relaxes bladder (pee to release water weight) Parasympathetic - contracts pupils - slows heartbeat - stimulates digestion - stimulates gallbladder - contracts bladder - allows blood flow to sex organs
83
Is it healthy to be in sympathetic control for long?
No can result in organ failure and death
84
Can you be in sympathetic and parasympathetic at same time
Nope
85
Node of ranvier
Gap between my selling sheath that Assist speed of impulse like myelin sheath
86
Not all nerves have ______ but those that do have increased ____
Myelin sheath Increases neural impulses
87
Terminal buttons
Contain neurotransmitters that are released to synaptic gap/cleft and migrate to dendrites of receiving neuron.
88
Nerves
Bundles of mylenated axons Always dedicated to specific functions (optic nerve) Exclusively contained in PNS
89
Neurons are located in
PNS AND CNS
90
Neuron types
Peripheral Sensory (afferent)- detects physical qualities Motor(efferent)- terminating on muscle/gland to move or release hormone Internuron (CNS only)- connect systems together and bring info into and out of the brain. Brain is made up of inter neurons.
91
85 Billion neurons but only a few million are
Motor or sensory neurons
92
Spinal cord and reflexes
Skin receptors pick up on heat or pain and send signal to spinal cord which sends it to inter heron that connects sensory neuron to motor neuron that moves finger away from pain. Other interneuron send information to brain and brain register pain after finger is moved away.
93
Glial cells
- dispose of cellular waste - insulate the axons of some neurons (myelin sheath) to increase speed of transmission - form the blood brain barrier
94
Resting potential
Neuron has stored up electrical chemical energy (polarized) Has capacity to create an action potential
95
Action potential
Release of stored up electrical energy (depolarization) Neuron fires
96
Refractory period
- absolute | - relative
97
All or none law
Size of action potential is not influenced by increases in the intensity of stimulation beyond the threshold. AP only travels away from the cell body down the axon
98
Myelin sheath
``` Nodes of ranvier (Salaries conduction) -diseases MS Guillian-Barré syndrome ```
