Respondents interpret different meanings from questions
Omission of

key terms when reading questions
Reliance on people’s memories of their

behaviour
Social desirability effect
Threatening questions - invalid answers
Interviewer bias

Слайд 3What is structured observation?
A method of systematically observing people’s behaviour
By

grouping behaviour into categories
Direct observation, not reports or inference, make

it an alternative to survey methods
Aggregates and compares behaviour of everyone in the sample
Uses a cross-sectional research design

Слайд 5Types of observation research
Structured/systematic observation
Participant observation (qualitative)
Non-participant observation
Unstructured observation (inductive)
Simple/contrived

observation - a form of participant observation where the situation

is left as-is or is changed (Webb et al.1966)

Слайд 6Naturalistic Observation:
Observation in natural (“real-world”) settings without an attempt

to intervene or change the situation.
Goals: Describe behavior as it

normally occurs, examine relationships among naturally occurring variables.
Naturalistic observation helps to establish the external validity of laboratory findings.
Naturalistic observation is used when ethical and moral considerations prevent experimental manipulation.
Role of emotions (emotional ties with observed peope|events)

Слайд 7Most psychological and marketing research involves observation with intervention.
Researchers typically

choose from three methods of observation with intervention in natural

settings:
Participant observation (‘observing participation’}
Structured observation
Field experiment

Observation with Intervention

Слайд 8Observer is an active participant in the natural setting he

or she observes.
undisguised: people in the setting know they are

being observed
disguised: people don’t know they are being observed

Disguised participant observation helps control for reactivity, one of the main problems associated with observation.

Participant Observation

Observer is an active participant in the natural setting he or she observes.undisguised: people in the setting

Слайд 9Reactivity occurs when people change their usual behavior because they

know they are being observed.
Participant observers may sometimes lose their

objectivity by becoming too involved in the situation.
Participant observers may influence the behavior of people they are observing.

Слайд 10Researcher sets up (structures) a specific situation in order to

observe people’s behavior.
Examples: clinical and developmental observations of behavior,

psychological testing

Structured observation is useful when behavior is difficult to observe as it naturally occurs.
Researchers often use confederates to create the structured situation.
Problems occur when observers don’t follow the same procedures across observations or observers, and when important variables are not controlled.

Structured Observation

Researcher sets up (structures) a specific situation in order to observe people’s behavior. Examples: clinical and developmental

Слайд 11Researcher manipulates an independent variable in a natural setting and

observes behavior (dependent variable).
There must be two or more conditions

to compare (independent variable).
Researchers often use confederates to create these different conditions.
Researchers attempt to have the most control in field experiments.

Field Experiment

Researcher manipulates an independent variable in a natural setting and observes behavior (dependent variable).There must be two

Слайд 13Researchers can obtain a comprehensive record of people’s behavior (e.g.,

video tapes) or select specific behaviors to record.
The method for

recording behavior determines how the results of the study are eventually measured, summarized, analyzed, and reported.

Слайд 14Researchers use narrative records when they want a complete (comprehensive)

reproduction of people’s behavior.
Examples: videotapes, audiotapes, field notes
Narrative records

should be made during or soon after behavior is observed.
Observers must be carefully trained.
Advantage: Can review the record often to observe behavior.
Disadvantage: Costly, time-consuming.

Qualitative Records

Researchers use narrative records when they want a complete (comprehensive) reproduction of people’s behavior. Examples: videotapes, audiotapes,

Слайд 15Selected Behaviors: Researchers choose the behavior they want to observe

and ignore other behaviors.
Researchers need to decide how they will

measure the behavior.
Examples: frequency of behavior, duration
Recording techniques include checklists and electronic recording and tracking.

Quantitative Records

Слайд 16The observation schedule
Must have a clear focus and be easy

to use
Categories must be inclusive (cover all options) and mutually

exclusive
It must be easy to operate
Specifies categories of behaviour to be observed and how to allocate behaviour to a category
Clear guidelines needed so that observers can distinguish between behaviour categories
A pilot study is useful to iron out any problems

Слайд 19Strategies for observing behaviour
Record incidents, events and interventions
Observe for short

periods of time, repeatedly
Observe for long periods of time, continuously
e.g.

Jenkins et al (1975): ‘the observation hour’
Time sampling
Record whatever is happening every x minutes
e.g. ORACLE study (Galton et al, 1980)

Слайд 20Sampling in structured observation
Sampling people
- Random sample of individuals to

observe
Sampling time periods
- Observe same individual(s) at different, randomly selected

times
Non-probability samples
- Cannot use a probability sample if there is no sampling frame, thus reduced external validity
Limited external validity, in any case
Sampling in structured observationSampling people		- Random sample of individuals to observeSampling time periods		- Observe same individual(s) at

Слайд 21Forms of sampling
Ad libitum* sampling
Record whatever is happening at

the time
Focal sampling (most common form)
Observe a specific individual for

a set period of time
Scan sampling
Record behaviour of everyone in the group at regular time intervals
Behaviour sampling
Observe whole group to see who was involved in a particular behaviour

* Latin for "according to a performer's wishes"

Слайд 22Issues of reliability and validity
Reliability
Inter-observer consistency (measured by Cohen’s kappa)
Intra-observer

consistency (lapses of attention)

Measurement validity

Слайд 23What is the reactive effect?
Webb et al. (1966) wrote about

the ‘reactive measurement effect’, in which the research subject knows

s/he is participating in research, thus invalidating the data:
• The guinea pig effect (awareness of being tested)
• Role selection (participants adopt a particular kind of role)
• Measurement as a change agent (the very fact of a researcher being present)
• Response sets (mostly relates to survey research when the respondent replies to a set of questions in a consistent but clearly inappropriate manner).

Reactive effects are likely to occur in any research in which participants know they are the focus of investigation.

Слайд 24Field stimulations
Salancik (1979) used ‘field stimulation’ to describe a form

of observation in which the researcher directly intervenes in a

setting and observes the results (a form of contrived, unobtrusive observation)
Quantification of the outcomes is the desired goal

Слайд 25Criticisms of structured observation
Imposes an irrelevant framework on the social

setting
Neglects the meanings and intentions behind behaviour (motives are inferred

but not investigated)
Neglects the social context of behaviour
Generates fragmented data - difficult to see the wider picture
Criticisms of structured observationImposes an irrelevant framework on the social settingNeglects the meanings and intentions behind behaviour

It is more accurate than interviews and

questionnaires
see what people really do, not what they say they

do

It is a useful accompaniment to other methods
