Q

What are the advantages and disadvantages of naturalistic observation?

A

Advantages
- provides insight into real world behaviour (high ecological validity)
- can observe behaviours that can’t be manipulated
- highly flexible (behaviours, antecedents, consequents)

Disadvantages
- time consuming and expensive
- unfocussed (difficult to explain behaviours)
- potential for observer influence
- interesting behaviour may be missed (no control, infrequent, only see public behaviours)
- hard to examine during observation
- ethical concerns (people haven’t explicitly given consent)

Q

How could we moderate the concerns of interference with behaviours and subjective interpretation in naturalistic observation?

A
  • well defined operationalisations / behaviour categories
  • train observers
  • multiple observers
  • video record for later analysis
  • Reduce observer influence: conceal observer or habituate participants to observer
  • Ethics: observe only public behaviours in public spaces

Q

Ways to observe in naturalistic observation

A

Disguised observation: conceal the observer (e.g. hiding inside a parked car to measure the speed without the awareness of the drivers)

Undisguised observation: habituate participants to observer (installing visible cameras next to rearview mirror)

Q

What is the purpose of intervention?

A
  • can cause infrequent events to occur (simulated emergencies, confederates instigating behaviour)
  • can facilitate repeat observations of the same behaviour
  • can manipulate conditions and make causal inferences
  • investigate the limits of an ability
  • observe normally private events

Q

What are the advantages and disadvantages of participant observation?

A

Advantages
- observation of secretive behaviours
- allows observation when there is no other way to conceal observer

Disadvantages
- extremely time consuming
- affect subjects’ behaviours inadvertently as the observer is interacting with them
- lose objectivity
- huge ethical concerns (lying to people, and an e.g. is that an undercover police was hooked on heroin after posing as an addict)

Q

What are the advantages and disadvantages of contrived observation?

A

Adv:
- do not need to wait for behaviours to occur naturally
- more time effective
- can manipulate IV if necessary

Disadv
- environment is less natural - therefore behaviours may be as well
- difficult to know what features of the environment need to be preserved
- may be impossible to habituate subject to being observed

Q

What is observation of physical traces?

A
  • researcher looks at physical surroundings to find reflections of subject’s previous activity
  • can be conscious (e.g. decorations) or unconscious (rubbish)
  • may be privacy concerns

Q

What is archival research?

A

Research involving looking at historical records to measure and describe behaviours / events occurring in the past.

22
Q

Advantages and disadvantages of archival research:

A

Adv
- no chance of interfering with behaviours
- can compare data from different times
- other researchers can look at the same data and draw their own conclusions

Disadv
- not actually witnessing behaviours / witnessing behaviours through another person’s lens (therefore multiple frames of bias)
- limits the inferences that can be drawn

23
Q

What is content analysis?

A

Study of documents and communication artefacts (images, text, media, manuals) to infer the occurrence, frequency and quality of behavioural events.
i.e. looking at advertisements shown at superbowl to understand the target market

24
Q

Advantages and disadvantages of content analysis:

A

Adv:
- identify patterns / features not immediately obvious to an observer
- clear and transparent how inferences and conclusions were drawn

Dis
- not witnessing behaviours (viewing through biases)
- analysis may not actually be objective

25
Q

What is observation of digital traces ?

A

Deliberate and non-deliberate artefacts of internet / digital technology user’s activities, transactions and communications
e.g. woolies change insurance rates by analysing what people buy in the store

26
Q

What are the advantages and disadvantages of digital traces?

A

Adv:
- extremely large datasets
- data driven approaches can find surprising patterns and making seemingly impossible predictions

Disadv
- difficult to explain results
- serious ethical concerns (gives researchers and companies power over people, difficult to regulate, and who ‘owns’ the data?)

27
Q

What is continuous sampling?

A

All behaviours that occur within a specified time period is coded. i.e. recording everything

28
Q

Advantages and disadvantages of continuous sampling

A

Adv:
- don’t miss any important behaviours (assuming we have the cognitive and physical capabilities)
- can see antecedents and consequents of targeted behaviour

Disadv
- expensive, time consuming, often impossible (how do you even record the data if you are always observing)

29
Q

Situation sampling

A

studying a target behaviour in different locations and under different circumstances / conditions
e.g looking at speeding in school zones (may look at different times of day, different locations, schools in different SES suburbs, driver characteristics (ps, learners, truckies)

30
Q

Advantages and disadvantages of situation sampling

A

Adv
- observer only has to focus on events of interest (time to record data, less fatiguing)
- enhances the external validity of findings (range of situations, times, locations)

Disadv
- may be expensive to carry out (visiting various locations)
- difficult to pre-plan if first investigation

31
Q

What is time sampling (aka interval sampling)

A

Observer decides in advance that observations will take place only during specified time periods (e.g. 10 minutes every hours, 1 hours per day) and records the occurrence of specified behaviour during that period only

32
Q

What are the advantages and disadvantages of time sampling? q

A

Adv
- observer only has to observe behaviours during certain times (time to record data, less fatiguing)

Dis
- may miss important behaviours (infrequent / irregular behaviours, antecdents and consequents)
- difficult to preselect times

33
Q

What is instantaneous sampling

A

observer decides in advance the pre selected moments when observation will take place and record what is happening at that instant

everything happening before or after is ignored

34
Q

adv and dis of instantaneous sampling (aka target time sampling)

A

adv
- only has to observe behaviours during certain times (time to record data, less fatiguing)
disadv
- may miss important behaviours - infrequent/irregular behaviours, antecedents, consequents
- difficult to preselect times if first investigation

35
Q

Event sampling

A

observer predecides one specific event or behaviour to be observed (once per observation interval) and all other times/behaviours are ignored

i.e. focussing on the first cars that took off when the traffic lights turned green

36
Q

Advantages and disadvantages of event sampling

A

adv:
- only has to focus on events of interest
- has time to record data, less fatiguing

dis
- we may miss important behaviours, antecedents, consequents
- observed behaviours may not generalize

37
Q

What is individual sampling

A

only one participant is observed at a time - focus shifts to another participant for the next intervaladv

38
Q

adv and dis of individual sampling

A

Adv
- observer only has to focus on one individual at a time (less likely to miss important behaviours), less fatiguing

Disadvantage
- time consuming and expensive
- if interesting behaviours are infrequent / unpredictable, we may miss one participant exhibiting them if they only did so while observer was focusing on others

39
Q

What is recording behaviour

A
  • what you record depends on goals of the study
  • you need: a comprehensive description of behaviours, or a description of selected behaviours
  • how the results of a study are ultimately summarised / analysed / and reported are dependent on how behavioural observations are initially recorded
  • quantiative or qualitative ?
40
Q

What are qualitative records of behaviour?

A
  • narrative records (written descriptions of behaviour, audiotapes, videotapes)
  • should be made during or soon after behaviour is observed, and observers must be carefully trained to record behaviour according to established criteria
41
Q

What are quantitative measures of behaviour

A
  • need to quantify the behaviours we observe / our qualitative records to perform statistical analysis
  • we can code behaviours according to precise and transparently reported schemes and then use those codes to generate single-number measures for statistical analyses
42
Q

The frequency method

A

Counting the instances of each specific behaviour that occur during a fixed-time observation period (e.g. count the number of ilearn posts)

43
Q

The duration method

A

recording how much time an individual spends engaged in a specific behaviour during a fixed observation period (time spend studying / revising)

44
Q

the interval method

A

diving the observation period into a series of intervals and then recording whether a specific behaviour occurs during each interval (logged onto iLearn that day)

45
Q

Calculating other measures

A

Sometimes there will be established measures of the characteristics / frequency of behaviours, but sometimes you will have to create your own.

46
Q

What is inter-observer reliability and why is it important?

A

The extent to which independent observers agree in their observations.
- can be increased by providing clear definitions about behaviours to be recorded, by training observers and providing feedback on discrepancies
- high interobserver reliability increases confidence that observations are valid
- the percentage of agreement is calculated by (number of agreements / number of opportunities for agreement)
- >90% is a ‘good’ measure

47
Q

What factors could negatively influence inter-observer reliability

A
  • error of apprehending: not being able to physically see due to the physical arrangement
  • observer error: inexperience, poorly defined behavioural units, observer drift
  • observer effect: due to the presence of the observer or stimuli
  • observer bias: expectancies of the observer
  • error of recording: poor techniques and equpiment, mental lapses
  • computational error: inappropriate choice of statistical test
48
Q

What is observer bias?

A

When researchers bias determines which behaviours they choose to observe and when expectations about behaviour lead to systematic error

Expectancy effect = when observers are aware of hypotheses for the outcome of the study

Reduce observer bias by keeping observers unaware (blind) of the goals and hypotheses of the study.

49
Q

Influence of the observer

A

individuals changing their behaviour when they know they are being observed (reactivity)

their behaviour is no longer representative of their normal behaviour (Hawthorne effect)

Methods to control this:
- unobtrusive (non-reactive measurement)
- adaptation (habituation / desensitisation to observer)
- indirect observations of behaviour

50
Q

What is intra-relater reliability?

A

the degree of similarity between different ratings made at different time points by the same rater for the same stimulus

important to ensure they remain consistent (may be inconsistent due to fatigue / boredom)
