Chapter 8: Non-experimental research: Observational, Case Study, Archive

Question 1

manipulation:

Answer 1

in an experiment, conditions or variables assigned or presented to a participant

Question 2

assignment:

Answer 2

in an experiment, pairing a subject with a condition or variable, according to the experimenter’s plan

Question 3

observation:

Answer 3

the record of a behavior

Question 4

Observational research takes two general forms:

Answer 4

naturalistic observation and participant observation, which vary in the degree of intervention by the researcher.

Question 5

4 main non-experimental research methods:

Answer 5

observation, archival research, case studies, and surveys

Question 6

The distinction between experimental research and non experimental research

Answer 6

1) The independent variable is not manipulated

Key words here are manipulation and assignment versus observation

2) data collection procedure often must forfeit some degree of control in return for obtaining the data
3) qualitative research interested in how individuals understand themselves and make meaning out of their lives

Question 7

qualitative research:

Answer 7

nonexperimental research that asks questions regarding how people make meaning out of the world

Question 8

correlational research:

Answer 8

nonexperimental research that measures two or more variables to determine the degree of relationship between them

The goals of correlational research are to describe and to predict

can determine a relationship between two variables, but cannot determine which variable is the cause and which variable is the effect

Question 9

Why is non-experimental research often called correlational research?

Answer 9

The term is somewhat misleading, however, because all research is correlational to the extent that it seeks functional relationships between variables

What makes research correlational in the common usage is the inability to manipulate some variable independently

Experimental research frequently is done as a follow-up to previous nonexperimental observations

Question 10

Observational research:

Answer 10

describe behaviour and, possibly, to examine the relationships among variables

can provide a rich source of hypotheses about the relationships between behaviours and the causes of behaviours. Thus, observation is often the first step in discovering the causes of behaviours

Question 11

archival research:

Answer 11

study method that examines existing records to obtain data and test hypotheses

study crime statistics in different countries to see if there is a relation between capital punishment and the murder rate

Question 12

case study:

Answer 12

exploratory study of an existing situation as a means of creating and testing a hypothesis

An investigator might study the victims of a natural disaster (such as the oil spill in the Gulf of Mexico) to determine its effects on their psychological health

Question 13

survey:

Answer 13

assessing public opinion or individual characteristics by the use of questionnaire and sampling methods

Question 14

hermeneutics:

Answer 14

the principles of interpretation of a text’s meaning

Question 15

How is naturalistic observation different from the casual observation that most people do?

Answer 15

Naturalistic observation is research conducted in such a way that the subject’s behavior is disturbed as little as possible by the observation process. The observation is made in the environment where the behavior naturally occurs

Question 16

unobtrusive research:

Answer 16

another term for naturalistic observation: the effort that researchers make not to influence, or obtrude on, the behavior being studied.

Question 17

nonreactive research:

Answer 17

another term for naturalistic observation emphasizing that the subjects are unaware that they are being studied

Question 18

physical trace and 2 kinds:

Answer 18

unobtrusive measure of behavior that uses physical evidence

use trace

• smudges on a pages book to see if the person spent a lot of time on that page

physical trace

• cigar butts after a poker party

Question 19

laboratory observation:

Answer 19

a type of observation that occurs in the laboratory rather than in the field

Question 20

Describe briefly three common ways of sampling behaviours in observational research

Answer 20

To describe behaviours accurately, a researcher must observe a sample of behaviour that is representative of the larger population of all possible behaviours.

Time sampling refers to selecting various time intervals, either systematically (e.g., every 15 minutes) or randomly, for their observations.

Event sampling refers to recording each event that meets a predetermined definition (e.g., fighting), which tends to happen infrequently.

Situation sampling refers to observing behaviour in as many different locations (e.g., in school playground and at home) and under as many different circumstances and conditions as possible

Question 21

Naturalistic observing has few hard-and-fast rules.

Three that should be mentioned are

Answer 21

• careful record keeping, detailed logs/checklists
• the use of a variety of types of measures, video/camera
• and care for privacy of the participants, ethics

Question 22

Propose a hypothesis that may be tested using physical traces:

Answer 22

Cave art in relation to sexual status hierarchy among ancient civilizations

Question 23

advantages and disadvantages of using physical traces as measures to test hypotheses about people’s past behaviour?

Answer 23

• Advantages:
  
  • It is unobtrusive and non-reactive so people’s behaviors are not influenced by the measurement process
• Disadvantages:
  
  • Can still run into ethical questions: example of looking at student’s library card
  • Erosion of evidence
  • Must consider alternative explanations and potentially collect data to rule out alternatives
  • Best to collect many different forms of evidence/data

Question 24

participant-observer research:

Answer 24

in which investigators participate in groups and record their observations.

The greatest challenge for the researcher is to gain access to the group, as White and McBurney (2013) point out. Once in, the participant observer may either take the role of an active participant of the group or stay in the periphery

must maintain a balance between reporting from the insider’s perspective and scientific objectivity.

Question 25

Under what conditions is participant-observer research useful?

Answer 25

most useful in studying a small group that is separated from the population as a whole, when little is known about a group, or when the group’s activities are not generally available to public view

Question 26

ethical problems that participant-observer research poses

Answer 26

* leads to problems of objectivity * converted by the religious group that they were studying * Sometimes it is possible to be open about the fact that you are there to study the group * By contrast, certain groups are hostile to the larger society and suspicious of anyone who shows an interest in them. * **From an ethical perspective,** it is best to be truthful where possible and to adopt a disguised strategy only when necessary * Participant observers cannot always obtain informed consent from the people they study. * Some researchers hold that participant-observer research is therefore always unethical. * Others point out that professionals such as journalists are permitted to engage in this type of practice. * They argue that if psychologists do not perform participant-observer research, they are withholding the application of psychological techniques and insights to important social problems

Question 27

Main Problems in Participant Observational Research

Answer 27

**first problem is reactivity.** The mere presence of the observer changes the composition of the group, and the act of observing changes the behaviours of the people being observed at least to some extent. **The second issue concerns the invasion of privacy.** Some researchers contend that participant observation is always unethical because the people observed have not given informed consent to be observed. This is particularly so when the observation is disguised. Others argue that the knowledge gained and the possible alleviation of social problems is likely to outweigh any harm caused by invasion of privacy. By entering the group, the observer (by definition) changes it to some large group may not be influenced much by an observer’s presence, whereas a small group may be influenced considerably. In general, participant-observer research is done in unusual groups that can absorb an observer whose presence would have little effect.

Question 28

archival research:

Answer 28

refers to research conducted using data that the archival data: factual researcher had no part in collecting. Present in existing records, or archives. The researcher simply examines or selects the data for analysis.

Question 29

2 reasons for archival research

Answer 29

* **Data that bear on the hypothesis may already exist**, and collecting new data would be wasteful. * Or **ethics or logistics may make it infeasible to conduct an experiment relating the variables of interest.** In other words because it has already been collected as a function of public record, the researcher's ethical concerns may be reduced

Question 30

Limitations of archival research:

Answer 30

* 1) most archival data are collected for **_nonscientific reasons._** Governments and private agencies collect the data for their own purposes, and such data often do not suit the purposes of the scientist. * for archival data to be useful to your investigation, the agency collecting the data must ask questions similar to yours or must inadvertently collect data that are valuable to your research question. * 2) because archival research is by nature carried out after the fact, **_ruling out alternative hypotheses for particular observed correlations may be difficult_** * 3) A researcher who relies on archival data is **_at the mercy of any biases that may have occurred in collecting the data._** Police records are notoriously subject to bias. * 4) some records are **_incomplete_** * 5) may be **_errors in records kept_** and data may not be as complete as hoped for

Question 31

limitations of archival research said another way

Answer 31

**First,** **inherent biases** may be present in archival data because the data are collected by others for a particular purpose, which means they are not necessarily designed to address the researcher’s specific question. **Second, only some records are produced and kept (called selective deposits) and some records are missing and incomplete** (called selective survival). **Third, the quality of data may not be as good as a researcher anticipates**, in that there may be **errors in record keeping**. **Fourth, changes may have occurred in the way records are kept or in the definition of categories (e.g., types of crime).** Finally, **reactivity may have been a problem when the archival record was produced**

Question 32

three basic steps in carrying out a content analysis

Answer 32

* The first step is to **identify a relevant archival source.** * Audio recordings of therapy sessions in the 1950s LSD experiments * The second step is to **select a representative sample from the source**. * Choose a case to focus on * The **last step is to code; that is, to define relevant descriptive categories and units of measure.** * How many times the person on LSD says the word GOD and how it relates to coherence * Code the latent meaning behind this to interpret the psychotherapy session

Question 33

What problems are associated with analysing archival data? What steps can researchers take to reduce these problems?

Answer 33

* One of the challenges of performing archival research is finding the specific archives that have the information relevant to your research needs. * Once you locate and gain access to an archive that has a good deal of material on your topic, **_preparation is vital before you actually visit the archive itself_**

Question 34

case study:

Answer 34

an intensive description and analysis of an instance, or case, of a phenomenon, such as an individual, an institution, a treatment, or an event.

Question 35

distinguish a case study from other nonexperimental methods

Answer 35

* the use of observation and archival methodologies * Sometimes this is an individual person, as in a psychiatric or neuropsychological case. * Other times it is an individual town or institution, as in a case of mass hysteria reported after a meteorite crash in Peru * it can be an individual method or treatment, such as the effectiveness of a new surgical intervention on a patient’s health

Question 36

advantages and disadvantages of case studies

Answer 36

* advantages. * First, they can provide insight into possible causes of people’s behaviour that can be tested later with more controlled research approaches. * Second, case studies allow for the study of rare events - example of kid with a tumor who could only see things on one side * disadvantages * First, researchers can rarely infer any cause-effect relationships from the results because of the presence of extraneous variables. * Second, subjective observer biases are likely to occur. * Third, it is difficult to generalize the results to other cases

Question 37

narrative case study:

Answer 37

a viewpoint expressed by telling and listening to stories that communicate meaning “I am never absentminded. I’ve never lost a single key. In fact I still have the house key my parents gave me when I was 10 years old, which I used until I was 37, when we moved. I’ve never lost an ATM card...

Question 38

What is the difference between research method and research procedure?

Answer 38

* **_Method_** is a broader term that encompasses all aspects of the study, including the logic of the design and the steps for carrying it out. * **_Procedure_** refers only to the latter—what the researcher does in translating the design into action. The design, for example, may be an experiment with two conditions that are both experienced by each subject. * Procedural concerns include whether each condition is tested on the same day or on different days. * After the design is completed, you should develop a clear idea of the exact procedure, or protocol, you will follow

Question 39

A protocol is

Answer 39

a list of the exact steps needed to test a subject from start to finish. Will you be greeting the participants? Giving them a written debriefing form? Etc... Write it down

Question 40

pilot study:

Answer 40

tentative, small-scale study done to pretest and modify study design and procedures

Question 41

Why is it necessary to conduct a pilot study?

Answer 41

* find the bugs in the procedure * almost always problems to be smoothed out. * Nearly every experiment we have performed without testing some pilot subjects has been disappointing. * Some researchers will not proceed to the main study until they have a good idea of what they will find in the full experiment, based on pilot work. * When a pilot study has been done, followed by a main study that has been run once and replicated once or twice, the credibility of the finding is increased tremendously over a single study that was not preceded by pilot work * Planning usually takes way longer than the actual experiment

Question 42

2 Problems with Observational Research

Answer 42

**Influence of the Observer** Reactivity: People tend to change their behaviours when they are aware of being observed. role demands can reduce the problem of role demands by limiting what the people being observed know about their role or about the hypothesis being tested in the study. **Observer Bias** Expectancies of the observer can lead to biases The use of electronic devices can help to reduce the likelihood of observer biases. So, too, can keeping observers “blind”; that is, not letting the observers know the reasons for the observations or the goals of a study
