1
Q

what are the limitations for theory of planned behaviour?

A

it assumes that:
1. intentions are explicit
2. it is not focused on external limitations
3. timeframe between intent and behaviour
4. good intentions are not always translated into behaviour

Q

what are the features of explicit measures?

A
  1. easier to obtain
  2. requires the ability and motivation to provide information
  3. may not be fully conscious processes
  4. social desirability problem in responding
  5. how exactly do we put things into words

Q

what are the key features of implicit measures?

A
  1. more difficult to obtain (more resources, time, money needed)
  2. they overcome biases
  3. not always measuring what they claim to measure

Q

what are the 3 steps to operationalisation?

A
  1. identify the concepts you want to study
  2. choose variable to represent them
  3. choose how the variables are measured

Q

what are the advantages of the mode?

Q

what are the disadvantages of the mode?

A
  • there can be more than one mode, or no mode
  • completely disregards other scores

14
Q

what are the advantages of the median?

A

good to use with ordinal data
- relatively unaffected by extreme/rogue scores
- useful for things like salaries, income

16
Q

what are the measures of dispersion?

A

range, variation, standard deviation

17
Q

what is the range?

A

difference between the minimum and maximum values

18
Q

what is a limitation of the range?

A

does not give an indication of the data between the minimum and maximum scores, which might be very high or very low values in relation to rest the data set

19
Q

how do you calculate variance?

A
  1. calculate mean
  2. subtract each data point from the mean
  3. square wash difference from the mean
  4. take an average of these numbers
20
Q

how do you find standard deviance?

A

calculate the variance then square root the answer

21
Q

what does variance indicate?

A

the spread of the whole group of scores

22
Q

what does data points far from the mean show?

A

a large variance

23
Q

what does data points close to the mean show?

A

a small variance

24
Q

why do we need distribution visualisation?

A

can quickly see range, central tendency, bimodality, extreme values

25
Q

what are episodic memories?

A

memories of particular events in our life. they have emotional valence

26
Q

what are semantic memories?

A

conceptual knowledge about the meaning of things. networks of associations (over time)

27
Q

what is a schemata?

A

patterns of expectations

28
Q

what is the aim of Ajzen’s theory of planned behaviour?

A

attempts to predict work related behaviours as a function of attitudes towards that behaviour, subjective norms and perceived control

29
Q

what does Hackman and Oldham’s job characteristics model aim to do?

A

attempts to predict job satisfaction as a function of certain important features of jobs

30
Q

what are the three steps to operationalisation?

A
  1. identify the concepts you want to study
  2. choose variables to represent them
  3. choose how the variables are measured
