Observational studies are
investigations where the
researcher manipulates an IV.
All types of research involve
some element of observation
Observational studies always
have demand characteristics
Validity refers to whether a
study measures or examines
what it claims to measure or
examine.
An undisclosed observation (or
covert) is a type of
observational study whereby
the participants are not fully
aware that they are being
studied

6.

A structured observation occurs
when the researchers control
some variables.
7. A coding scheme generally
provides qualitative data
8. A participant observation does
have a problem that the
observer may lose some
objectivity.
9. A controlled observation occurs
when the researchers control
some variables.
10. Observational studies tend to
be high in ecological validity.
Lesson Objectives
By the end of the lesson you …
• Must be able to describe (AO1) the
observational method and its components.
• Should be able to evaluate the observational
method.

Observation
• Participant Observations

Objectivity?

– Take part in what you’re observing

• Non-Participant Observations
– Just observe – no interaction

• Disclosed (overt) Observations
– Participants aware of observer

Observer effect
Act differently

• Undisclosed (covert) Observations
– Participants unaware of observer

Ethics!
Observation
• Structured Observation

Event Sampling

– Coding scheme is used to record behaviour
– Quantitative data collected

• Unstructured Observation

Time Sampling

– Researchers just record what’s going on
– Qualitative data collected (usually)

• Controlled Observations
– Researchers manipulate some variables
Observation - Sampling
Event Sampling
Time Sampling
• Coding Scheme
• Researcher decides
on a time and then
• Researcher records
records what is
an event every time it
occurring a at that
happens.

Observation
Reliability

Validity

• Difficult to replicate
observation –
confounding variables.
• Check consistency within
observations with interrater reliability (≥ 0.8)
• Improve reliability by
using good coding
scheme.

• If participants know = low
validity
• Observer bias = low
validity
• Improve by using wider
categories or single-blind
technique
BPS Ethical Concepts (1990)
• Informed consent
of participant
• Right to withdraw
• Debriefing
• Deception

• Observation
• Protection of
participants
• Colleagues
• Confidentiality
• Competence

When conducting research psychologists should
adhere to these.
