Q

Important issues to consider in observational research:

A
  • Hawthorne effect: demand characteristics/reactivity/observation bias. subjects change behaviour because they know they are being watched.
  • Identification of categories
  • inter-rater reliability: both observers are observing things consistently

Q

Ways to avoid Hawthorne effect?

A
  • observe public behaviours in public places

- habituate participants to being observed

Q

What are behaviour categories?

A
  • categories of behaviour made by observers to reduce subjectivity
  • prior to making observations, researcher identifies categories of behaviour we want to observe (eg., group play, play alone, aggression, social interaction).
  • list exactly which behaviour count as examples of each category
  • these categories establish a clear operational definition of each construct being examined

Q

Ways of QUANTIFYING observations

A

-FREQUENCY METHOD: number of instances that a behaviour occurs
-DURATION METHOD: how long does a behaviour last?
INTERVAL METHOD: divide period of observations into intervals and record whether behaviour occurs in each interval (yes or no)

Q

In the frequency and duration methods of quantifying observation, are the same behaviours being measured?

A

yes, but they are being quantified differently

Q

Ways of RECORDING observations?

A
  • TIME SAMPLING: observe for a specified period then record observations. Decide timeline. Watch, record, repeat. Stop at end of period.
  • EVENT SAMPLING: for interval 1, looking for behaviour 1. Interval 2, behaviour 2, etc.
  • INDIVIDUAL SAMPLING: looking at 1 person at one interval, and then another at the next interval. Group of people, observe 1 at a time. interval 1–>person 1. Interval 2 –> person 2

Q

Ways to OBSERVE behaviours?

A
  • NATURALISTIC OBSERVATION: less interaction, observe from afar.
  • PARTICIPANT OBSERVATION: researcher participates in the same activities as the subjects.
  • CONTRIVED OBSERVATION: behaviour in a specifically designed setting/situation

Q

Your are interested in whether blinking rate is associated with anxiety. You record the number of blinks for a participant during a 30-second period they are either reading a story about bicycle thefts on campus vs reading about a new campus art exhibit.

  1. what method of observation are you using?
  2. how are you quantifying your observations?
  3. what observation sampling technique are you using?
A
  1. method of observation: contrived
  2. quantifying observations: frequency
  3. sampling technique: time-sampling

Q

What problems in the following example:
A group of researchers is interested in the effort put towards training of dog owners with different sized pets. They go to a dog park and obtain consent from their participants. They decide to observe one dog owner per minute. Researcher 1 records the amount of time
spent correcting behaviour (e.g., scolding) by dog owners as indicating they are putting effort into training. Researcher 2 records the amount of time showing affectionate behaviour (e.g., petting). Researcher 1 concludes that larger dog owners put more effort in,
and researcher 2 concludes the opposite. What are the biggest
issues here?

A
  • Hawthorne effect
  • inter-rater reliability
  • both observers are observing different beahviours. Should be the same.

Method of observation: naturalistic
Sampling technique: individual sampling
Quantifying technique: duration method

Q

Self-report measures of behaviour, opinions, personality characteristics, etc. falls into what kind of research design?

A

Survey research design

17
Q

Types of survey questions:

A
  • demographic questions (eg., what is your age, income, occupation, etc?)
  • open-ended questions (allow participants to respond in their own words. eg., what do you think about the current availability of food on campus?)
  • restricted questions (presents participants with a limited number of response alternatives. Eg., multiple choice)
18
Q

What are some issues with rating scales?

A
  • people tend to avoid extremes

- sometimes people select “neutral” for everything

19
Q

What is a Likert-type scale?

A

-a rating scale with an extreme on each end, neutral in the middle. Equal spacing between numbers (eg., strongly disagree, disagree, slightly disagree, neither agree nor disagree, slightly agree, agree, strongly agree)

20
Q

What is a semantic differential rating scale?

A

semantic differential presents pairs of bipolar adjectives (such as happy—sad, boring—exciting), and asks each participant to identify the location between the two adjectives that best describes a particular individual

21
Q

A pain scale in the ER is an example of what kind of rating scale?

A

non-verbal

22
Q

Pitfalls of survey questions

A 
UNNECESSARY COMPLEXITY:
-jargon
-vague terms
-overloading working memory
DOUBLE-BARRELED QUESTIONS
-asking two things at once
LOADED QUESTIONS
-direct responses a certain way
NEGATIVE WORDING
-agreeing with the question means disagreeing with its content
23
Q

What survey question pitfall can be identified in the following:
To what extent do you agree that professors should not be required to take daily attendance?

A

negative wording

24
Q

What survey question pitfall can be identified in the following:
I enjoy studying and spending time with friends on weekends

A

double-barreled

25
Q

What survey question pitfall can be identified in the following:
Do you support the legislation that would unfairly tax hard-working farmers?

A

Loaded question

26
Q

What survey question pitfall can be identified in the following:
Do you believe the relationship between cellphone behaviour and consumption of fast food is orthogonal?

A

Unnecessary complexity

27
Q

What survey question pitfall can be identified in the following:
Restaaurants should not have to be inspected each month

A

Negative wording

28
Q

What are response sets?

A

-answering all Q’s in a particular manner (eg., yea-saying and nay-saying. Social desirability)

29
Q

How can you identify whether a person has simply been responding “yes” or “no” only on a survey?

A

-by including reverse-scored items

30
Q

One way to prevent responses based on social desirability from occurring:

A

insert sensitive questions in the middle of the survey

31
Q

How are surveys conducted?

A
  • questionnaires

- interviews

32
Q

Researchers are interested in the different methods teachers use to maintain control in junior high classrooms. They go into four 8th grade classrooms, each with approximately 25 students, and record how many times teachers have to discipline students within a one hour period. They notice that the teachers rarely have to correct behaviour from their students and conclude that junior high students are generally well-behaved without any special methods.

  1. ◦ What kind of observation is this?

  3. ◦ What could be an issue with this study?
A
  1. observation: naturalistic
  2. quantifying: frequency method
