Psyc Flashcards
A theory is…
a systematic way of organising and explaining observations
- leads to new predictions that can be tested
A good theory:
- fits the known facts
- makes new testable predictions
- is falsifiable
Goals of scientific method…
- observe
- understand
- apply and control
5 steps in scientific method:
- formulate a testable hypothesis
- design a study
- conduct the study and collect the data
- Analyse and evaluate the data
- report the findings
Bias - Demand Characteristics
- participants respond in the way they think the experimenter wants them to respond
Bias- Placebo effects
participants condition improves because they believe the procedures will help them
Experimenter bias
the tendency of experimenters to let their expectancies alter the way they treat their participants
Controlling bias
single-blind studies - either the experimenter or participant is unaware of the purpose of the study
double-blind study - both experimenter and participant are blind to the purpose of the study
Quasi experimental designs
- share logic and features of experimental design but participants are not randomly assigned
- used when studying individual differences, or due to constraints
Compliance
agreeing to a request from someone who does not have the authority to make you obey
Foot in the door technique
A person makes a small request, then makes a larger related request
Power of commitment
- once a choice has been made people feel pressure (from themselves and others) to act consistently with that commitment even if it becomes increasingly costly
- foot in the door is a good example of how we can feel the power of commitment.
- once we make a commitment we tend to add new reasons to justify the decision
Low balling
A person makes what seems to be a reasonable request, and then reveals a hidden cost afterwards
optimal conditions for compliance
commitment can be increase by
- getting commitment in writing
- getting people to make public commitments
- making people feel like the commitment was freely chosen
the power of reciprication
- one of the most powerful norms is society is that if someone gives you something you give something back
- people feel compelled even by a stranger
Door in the face technique
a person makes a ridiculously large request and then follows it up with a smaller, more reasonable request
Contrast effects
humans are better at making relative judgements than absolute judgements - when preceded by a very large request, subsequent requests seem more reasonable
Obedience
commands us to change our behaviour and we do
Milgram - electric shock study
Key contributing factors for obedience
- high status of the authority figure
- absence of a clear cut point for disobedience
- belief that authority figure will take responsibility for actions
- barriers for empathy for victim (obedience is reduced the greater the potential for empathy)
Attitudes
an attitude is an association between an act or object and an evaluation 3 components: - beliefs - feelings - behavioural tendencies
Value is a
broad abstract goal that lack a specific referent point
opinions are…
verbal manifestations of an attitude
schemas are…
- cognitive structures that represent knowledge about a concept or type of stimulus.
- formed on the basis of past experience
- not necessarily affective whereas attitudes suggest how people feel about objects
attitude change focus on 4 factors
- communicator
- message
- the audience
- the channel
Non verbal communication
definition: the transfer of information by means other than words
- 60 - 65% of info and meaning is communicated nonverbally
- nonverbal communication becomes greater when making judgements about a persons leadership ability
- reliance on nonverbal s greater when nonverbal and verbal channels conflict
- children place greater reliance on verbal cues than adults
- words communicate facts. nonverbals - emotion, attitude and interpersonal information
Emblems
= language can be used to: - insult - give directions - greetings - signalling departure - replying - more subtle and complex info
Illustrators
nonverbals that help complement or clarify the meaning of the words
