Clinical Perspectives and Social Flashcards
What are the key aspects of psychology that make it a science?
Empirical measurements
Scientific method
Experimental control
What are the statistics for the occurrence of PTSD?
10-20% survivors
4% Australians
Define PSTD
Anxiety disorder affecting the memory. Victims experience distinctive, vivid reexperiences of memories (referred to as ‘flashbacks’). These are often brought on by triggers (place, smell, sound)
What is usually done to minimise PTSD?
Psychological debriefing has been the standard practice for 30 years. It is conducted within 48 hours of traumatic event. It is believed that talking about the event will decrease the likelihood of PSTD.
Eg: $90 mill donated to trauma debriefing after 9/11
What are the aspects of the scientific method which show debriefing doesn’t work?
Measurement - must happen before and after treatment
Comparison condition - must have a control
Controlling for bias - randomisation
Experimenter/assessment bias - assessments are conducted blind
Double blind studies
Replication and peer review
Quality checks
Give and example of debriefing trials
Often occurs in regions of crisis. A study in Peshawar (Pakistan) with 60% from war trauma, 20% from natural disasters.
They must be random, blind assessments, strict protocols, standardised assessments and checks that interventions are valid
What is Classical Conditioning?
Process used to cause organisms to associate a certain stimuli with an emotion/sensation
Identify the scientific techniques used to disqualify psychological debriefing
Measurement: measured patients before and after treatment.
Controlling for bias: randomisation
Experimenter bias: assessments were made blind
Double blind studies
Comparison condition: need for a control
Replication and peer review
Quality check made by third party
Define Classical Conditioning
Process by which an individual learns to associate a particular stimuli with an emotion/sensation
Describe classical conditioning experiments using rats
Rats were given an electric shock whilst a light was turned on. Rat associated light with pain so when light was turned on, even when there was no shock, the rat was afraid. However, over time the rat began to learn that the light is a sign of safety (extinction learning) as it no longer experiences the pain.
Give modern day example of classical conditioning
Training firefighters were given electric shocks when exposed to certain colours. They then measured how long it took for them to learn that the colours were not associated with harm. After four years, they remeasured the firefighters and found that those that were initially poor at extinction learning had PTSD
What is exposure therapy?
Reintroducing a patient to triggers of PTSD in a safe way (often through talk therapy) in order to change their perception of the world
What is the amygdala?
Region of the brain responsible for fear conditioning - is particularly active in PTSD (association between event and triggers)
What is the MPFC and what does it do?
Region of the brain that inhibits the activity of the amygdala. Used for extinction learning. During PTSD, this region is less active.
What is glutamate and what does it do in the brain?
Glutamate is a major excitatory neurotransmitter. Studies show that it is linked to extinction learning. When glutamate is given before a trauma, individuals are better at extinction learning.
Anxiety therapy also uses glutamate to improve results in exposure therapy.
What proportion of people successfully respond to exposure therapy?
2/3
What are the four goals of scientific psychology?
Description, prediction, identify/explain and facilitate treatment.
What are the important aspects of scientific psychology?
Objective data collection through empirical testing
Systematic observation through isolation and manipulation of variables
Reliance on evidece to formulate theories
What is change blindness?
Individuals are not good at observing things we are not looking for. We are less likely to notice changes we are not expecting.
What percentage of people did Milgram and behavioural psychologists believe would administer the lethal shock
2%
What percentage of people actually administered the lethal shock in Milgram’s studies?
65%
Describe the ‘Introspection’ movement
Introduced by Wilhelm Wundt (and Leipzig). They trained observers to report on their own consciousness (phenomenology) under different conditions. It focusses at looking inwards. Movement failed as it was unreliable.
Describe the ‘functionalism’ movement
Introduced by William James who studied psychological processes in terms of function and tried to develop definitions of psychological terms. It is consistent with the evolutionary framework. Functionalism focusses on identifying the rules/steps of behaviour, rather than the underlying mechanism.
Jerry Fodor believed this system could be used for software development.
Describe the ‘behaviourism’ movement
Early challenge to introspection (Nth America: 1900-1950). Believed that only observable behaviours could be scientifically and empirically measured. Radical behaviourism was lead by B.F. Skinner and John Watson. They belied that ‘internal states’ are not observable so cannot be studied.
Psychoanalysis also challenged introspection. He argued that some behaviours are unconscious.
What is the role of studying psychological processes in the brain?
Studying brain processes can only support an understanding of psychological processes; it can’t explain them.
Who is considered the ‘father’ of social psychology
Gordon Allport
How did Allport define Social Psyc
“how thoughts, feelings and behaviours are influenced by the actual or implied presence of others.”
What is the aim of social psychology?
To study how affect, cognition and behaviour interact at different levels by studying the interaction between situational and personal influences
Distinguish between situational and personal influences
Situational: external factors
Personal: internal factors
What are the different levels that social psychology studies?
Individuals
Dyads
Group
Society
Define: loneliness
The mental sense of that social needs are not met. Can lead to an increased risk in health issues.
What are the limitations of common sense?
Cannot distinguish between causality and coincidence, unfalsifiable and retrospective.
What are the steps of the scientific method
Observation - Theory - Prediction - Research design - Data collection - analyse and revise theory
According to social psychology what are the essential components of science?
Accuracy, Objectivity, Skepticism and open-mindedness
Describe the two different types of research methods in social psychology
- Descriptive Methods (studies that what and when). They study ABC in their natural state with little interaction. Can be either naturalistic observations, archival studies or surveys.
- Experimental Methods (studies the why/how). Study social processes by isolating and manipulating key variables to determine causality. Can be either a field experiment or a laboratory experiment.
Describe first impressions and the influential factors
First impressions are lasting and are based on limited information (0.1 secs).
Influenced by facial cues (baby facedness, familiarity, emotional resemblance and fitness), demographics and behaviour.
What are Internal dispositions?
Personal tendencies
What are external situations?
Environmental influences in behaviour
What did Herald Kelly suggest we consider when making attributions?
Consistency: how frequently they do it
Consensus: do others do it?
Distinctiveness: do they do it only in this situation
Describe FAE
Fundamental Attribution Error (Correspondence Bias) is when we make dispositions from situationally induced situations. Occurs when the focus is on the other person
