Methods
Variable experimenter chooses to manipulate or change
Independent variable
These take place in a situation or environment that is artificial to the participants in the study
Lab experiments
"To investigate if adults with high functioning autism or Asperger's syndrome would be impaired on a theory of mind test called The Eyes Task"
Aim
To investigate whether positive false memories for loving asparagus can be suggested and then change their childhood memories of liking asparagus.
Investigate consequences of suggesting positive false memories in terms of the effects it has on liking and choosing asparagus
Aims for Experiment 1
Suggests that doodling can improve concentration and the memory of a conversation.
Psychology being studied
It is always hopes that the IV directly affects this in an experiment.
Dependent Variable
When researchers use a pre-existing or naturally occurring IV
Natural Experiment
AS/HFA
"Normal Adults"
Cambridge Students
IQ Matched Participants
Variable groups/Experimental Groups
People were told they would be completing a series of questionnaires to help study the relationship between ______ and _______
Food Preferences, Personality
40 members of the Medical Research Council, aged between 18 and 55 were acquired via this sampling technique.
Volunteer
Experiments that take place in the participants own natural environment.
Field Experiment
Laboratory experiments have high levels of standardization and can be replicated to test for reliability. This statement is an example of what?
Strength of a Laboratory Experiment
Type of correlation found between AQ and Eyes test
Negative
Replicate findings from Experiment 1
To examine a possible underlying mechanism of false memories by looking at whether the sight of asparagus is more appealing to people after the false manipulation about asparagus.
Aims for Experiment 2
% of correct party goers/places
Dependent Variable
A researcher is using this when they ask participants to answer a series of questions in the written form
Questionnaires
Can collect rich and detailed data, making findings more valid.
This statement is an example of
Strength of a case study
"The performance on an advanced test of theory of mind."
DV
As there were many controls, (rating scales and false feedback given), the researcher can be more confident that it was the false feedback that was affecting participants' liking of asparagus.
This statement is an example of
High Validity / Strength of Experiment
Dull mock phone call about party
2.5min long in a monotonous voice
A4 paper with 10 shapes per row with 4.5cm margin
Quiet, dull room
All examples of what?
Controls used in study
Case is unique and generalizations are difficult to make.
This statement is an example of
Weakness of a case study
These test how the far the actual findings have deviated from chance.
Null hypotheses
Forced choice between two response options, too easy mental states, Semantic opposites, and Comprehension problems. Are all examples of what?
FHI, RQ
FPQ, FCQ
What do these acronyms stand for?
Food History Inventory, Restaurant Questionnaire.
Food Preference Questionnaire, Food Cost Questionnaire.
The use of independent measures design may have affected the results in Andrade. What type of variable, specifically, can have an effect when using the independent measures design?
Participant variables
