Q

Order effects

A

Order effects can occur when using a repeated measures design as a result of 1 participants taking part in both conditions the research I cannot see if it was a change in the independent variable that affected the dependant variable or if it was the order in which the participants did the conditions

Q

Randomisation

A

Randomisation is the process of making something random random means having an equal chance of being selected the process is used to reduce the effects of researcher induced bias

Q

Pilot study

A

A pilot study is a small scale study completed before a main study begins the aim of conducting a pilot study is to identify any Flaws and rectify them before conducting the main large-scale study this will ultimately save the research of time and money

Q

What is a repeated measures design

A

Where participants take part in both conditions of the independent variable we compared the results of the dependant variable of the participant from both conditions

Q

What are the positive aspects to a repeated measures design

A

Half the number of people needed compared to using an independent groups design. The participant are the same so you have no differences between people reduced participant variables.

Q

What are the negative aspects to a repeated measures design

A

The order of conditions may affect performance. Order effects. By taking part in both conditions the participants may guess the aim of the study and so exhibit demand characteristics

Q

What are demand characteristics

A

Where participants change their behaviour to give the researcher the result they expect or to purposefully contradict their aim

Q

What is an independent groups design

A

Participants are randomly allocated to one condition of the independent variable one group undergoes one condition and the other group undergoes the other we then compared the performance of two groups

25
What are the positive aspects of an independent group design
There are no order effects because people only take part in one condition. Often the same materials can be used for the other condition (save time and money so is practical). Participant cannot work out the aim of the study because they only take part in one condition so it reduces demand characteristics
26
What are the negative aspects of an independent group design
The researcher cannot control the effects of participant variables (the individual differences between people for example intelligence. Participants in group a may have better memories than in group B. Double the amount of participants needed and repeated measures in order to end up with the same amount of data
27
What is a matched pairs design
Participants are matched based on similarity or key characteristics (for example similar ages,, intelligence) believed to have an influence on the dependant variable. The characteristics must be relevant to the area of study. One of the pair is then randomly allocated to condition a and the other condition and undertake different conditions of the independent variable
28
What are the positive aspects of a matched pairs design
Reduces the effect of participant variables. These are differences between people which may influence the dependant variable. Easier to cross compare results between individuals to see and assessed the impact of the independent variable.
29
What are the negative aspects of a matched pairs design
Time-consuming to test participants and match them based on important characteristic related to the study. Difficult to reduce all participant variables. Matches are created based on what the research think will affect the dependant variable but participants may have differences unbeknown to the researcher than influence the dependant variable
30
Counterbalancing
Half the participants to one condition first and the other half do the other condition first then they swap. It is used to control for order effects in a repeated measures design
31
What are the three types of experimental methods
Lab Field Natural
32
What are the non experimental methods
Correlation Obsevational Self report Case
33
What is a lab experiment
Refers to a room designers specifically for the purpose of scientific investigation
34
Positive aspects of a lab experiment
Standardised procedures High level of control over variables Easy to replicate
35
Negative aspects of a lab experiment
Unrealistic Low in ecological validity Cannot be generalised Participants may figure out the aim of the study and show demand characteristics
36
What is a field experiment
The setting of the experiment takes a very interesting a real world situation for the participants. However there is still an IV that is being manipulatec by the researcher and it's affect on the DV is measured
37
What are the positive aspects of a field experiment
High ecological validity Results can be generalised Reduaced demand characteristics
38
What are the negative aspects of a field experiment
Les control over extreanuous variablss caidual relationships difficult to establish Replicstion is hard Patience ence is required
39
What is a natural experiment
The researcher takes advantage over a naturally occurring IV the changing IV would occour weather the researcher was present or not the DV is still measirexd
40
Post I've aspects of natural experiments
High in ecological validity Behavoiors can be a piece to real world situations Reduaced demand characteristics
41
What are the negative, aspects of a, natural experiment
Unable to reduaced the effects of extreanuous variables Hard to establish casual relationships Conditions cannot be replicstec Low in reliablitlity Cannot randomly allocate particpnets to conditions sample bias
42
Why were the names of the people who took part in psychological experiments changed from subjects to participants
To show respect The term "subject" suggests that they are powerless and unhuman
43
What is informed consent
Participants should, know, enough details about the study in order to give, permission to take part
44
Deception
Lying to owple, and decidcing them about the aim of the, study
45
Right to withdraw
Participants, should be given the right to withdraw themselves and their data from the study at any time
46
Protection from harm
Participants should not be either physically or psycolologically harmed wine pearticipafing in research
47
Debrifing
Participants should be told what the study was about before they leave this, is essential when you have, decieved participants
48
Confidentiality
Meansckeepong personal information confidential and when writing reports keeping participants, data annonoymous
49
Privacy
Psycolologists should not intride on participants, private life or space without their permission
50
What are the 4 data types
Qualitatative Quantitative Positive Negative
51
What is qualitative data
Qualitative data is written or spoken it often describe something. It is not numerical but rich in detail and I include a reason as to why the behaviour occurred.
52
What is quantitative data
This is numerical data it often relates to how much how far how many or how long it doesn't include a reason or explanation for the numerical answer given
53
Give an example of qualitative data
Answers given an interview, descriptions of an observation, explanations or opinions in a questionnaire.
54
Give examples of quantitative data
Percentage of people who obeyed the number of items recalled how long participants rated for
55
What is primary data
Any data that has been collected by the psychologist for the purpose of their own research or investigation it is of Direct relevance to their research aim and hypothesis
56
What is secondary data
Data that was originally collected by someone other than the psychologists but the psychologist will use it for their own research purposes
57
Give an example of primary data
From a questionnaire Observations Results from an experiment
58
Give an example of secondary data
Official statistics (prime education health) Results from another study Documents Diaries newspapers
59
What is a case study
An in-depth investigation into an individual or a group of people
60
Name the 6 types of observational studies
Naturalistic, controlled, overt, covert, participant, non-participant
