Q

Why is psychology difficult to study

A
  1. everyone already knows some psychology. We make generalizations because of our place within society. we need to let go of what we think we know in order to learn psychology formally
  2. the processes that underlie human behavior cannot be directly seen or measured. we cannot see in the mind; we can only infer what is happening in the mind of those we observe.

Q

what is a confounding variable

A

an unmeasured third variable that influences both the supposed cause and the supposed effect.
Coffee drinkers may smoke more cigarettes than non-coffee drinkers, so smoking is a confounding variable in the study of the association between coffee drinking and heart disease. The increase in heart disease may be due to the smoking and not the coffee.

Q

what is validity

A

how accurately a method measures what it is intended to measure. If research has high validity, that means it produces results that correspond to real properties, characteristics, and variations in the physical or social world.

26
Q

What are some data collection methods

A

direct observation
surveys
interviews
psychological tests
psychological recordings
examinations of historical records

27
Q

what is direct observation

A

the participants behaviors are watched and recorded as objectively and precisely as possible. instruments such as a stopwatch or video recorder may be used.

28
Q

what are surveys

A

participants are given a series of written questions designed to obtain information about their attitude’s opinions and or specific aspects of their behavior.

29
Q

what are interviews

A

a face-to-face conversation is conducted to obtain information about specific aspects of participants attitudes opinions and behavior.

30
Q

what are psychological tests

A

participants are administered a standardized test to obtain a sample of their behavior. tests are generally used to assess mental ability or personality traits e.g. IQ test.

31
Q

what are psychological; recordings

A

an instrument is used to monitor and record a specific physiological process in a participant. e.g. measures of blood pressure, heart rate, muscle tension and brain activity.

32
Q

what is examination of historical records

A

the psychologist analyses existing institutional records (archives) such as census, economic, medical, legal, education, and business records.

33
Q

what are the two types of data

A

quantitative data and qualitative data

34
Q

what is quantitative data

A

data that is numerical, it can be put in categories (high or low), order (largest to smallest) or measured. this type of data increases the objectivity of a study.

35
Q

what is qualitative data

A

data that is non-numerical. feelings, characteristics. usually considered less reliable but gives a more in-depth description of the situation.

36
Q

what is census

A

data is collected from every member of the population

37
Q

what is a sample

A

data is collected from some members of the population- a subgroup of participants

38
Q

what is a biased sample

A

a sample that does not accurately represent the population

39
Q

what is a representative sample

A

a sample that accurately reflects the important characteristics of the population.

40
Q

what random sampling

A

each member of the population has an equal chance of being selected in the sample.

41
Q

what are the three types of psychological research methods

A

experimental designs.
quantitative, observational designs,
qualitative designs

42
Q

what are the characteristics of experiments

A
  1. participants should be allocated to the experimental conditions (the experimental group) and control group randomly
  2. an independent variable is manipulated by the researcher to produce a change in a dependent variable.
  3. all other variables which might influence the dependent variable are held constant of eliminated.
43
Q

what are the characteristics of experimental designs

A

researcher decides on the variable being tested and deliberately varies it to see the effect it has on the dependent variable. participants are usually placed in groups with one group being placed under normal conditions as the control group
other variables are controlled as much as possible to ensure confidence in the results of the experiment.

44
Q

what are the advantages and disadvantages of experimental research

A

advantages: one or more variables can be manipulated, and control of others means the researcher can infer causation. studies can be replicated.

disadvantages: the experiment may raise ethical concerns. findings may not be applicable to real life situations.

45
Q

what are the characteristics of quantitative observational designs

A

researcher measures the effect of the independent variable by observing natural occurring behavior rather than deliberate manipulating of the variable. used predominately for practical and ethical reasons. situations are found in which people already differ in the desired variable and the behaviors are then observed or measured in some way.

46
Q

what are advantages and disadvantages of quantitative observational research

A

advantages: it is possible to study variables that would be unethical impractical or impossible to manipulate.
disadvantages: there is a lack of control over variables. no random assignment of participants, means it is not possible to infer cause and effect.

47
Q

what are the characteristics of qualitative designs

A

the behaviour of the subject is not observed or measured directly. subjects are asked to discuss or describe their behavior, thoughts, or feelings in certain circumstances. large sets of data can be collected in a fairly short period of time then analyzed to answer the research question. common methods include focus groups and the Delphi technique (responses to open-ended questions are answered then responses are followed up by the further issues raised.

48
Q

advantages and disadvantages of qualitative research

A

advantages: allows study of complex real work issues. open ended questions may lead to important information that otherwise may not be revealed.
disadvantages: data may be distorted by the bias of the participants and or the observer.

49
Q

what is a case study

A

a research method that involves the collection of detailed information usually of a highly personal nature and an individual, family, or small group

50
Q

how is case study data collected

A

interviews, direct observation, examination of past records, psychological testing.

51
Q

what is the longitudinal method in case studies

A

the same group of participants is studied repeatedly over a long period of time.

52
Q

what is the flow chart for choosing the best design for your research

A

is the data qualitative?

yes–qualitative design

no– can the IV be randomly allocated?

yes– experimental design

no–quantitative observational design.

53
Q

What are ethics

A

are moral principles and standards that guide individuals to distinguish between right and wrong, or good and bad.

54
Q

what are ethical codes

A

are standard of conduct or rules of behaviour adopted by various professionals.

55
Q

What are the ethical guidelines in psychology

A

informed consent, voluntary participation, deception, debriefing, withdrawal, confidentiality, possible harm, professional conduct

56
Q

what is informed consent

A

Participants should not take part in any psychological research unless they give informed consent in writing. Participants must be made aware of the aim of the research and all procedures involved.

57
Q

what is possible harm

A

participants should not be harmed in either a physical or psychological way. it is the responsibility of the researcher to protect the rights of each individual. it must be ensured that the participants will suffer no lasting physical or psychological harm.

58
Q

What is voluntary participation and withdrawal

A

all participants must participate in the research willingly and not be forced in any way. they should be made aware that they have the right to withdraw from the research at any point for any reason.

59
Q

What is debriefing and deception

A

Participants should not be deceived over the nature of the research, or any procedures involved in the research. after the research, the psychologist conducting the research must be prepared to explain and discuss all the procedures and results with the participants. the research must allow for an explanation of the outcomes to participants after it has been completed.

60
Q

what is confidentiality

A

results of the research should remain confidential, and the participants’ identities should not be revealed. the results must avoid invading the participant’s privacy.

61
Q

What is proffesional conduct
