A

At what distance two distinct points become noticeable to participant 50% of the time

97
Q

What are baseline measurements?

A

Often used in single subjects, can act as “control” condition, important that baselines are stable

98
Q

Why can single subjects be useful?

A

Ethics: is it okay to withhold treatment from those in placebo?

Practicality: Difficult to recruit people with specific conditions/disorders

99
Q

What are problems averaging across groups?

A

Comparing group means can be difficult if one group has high variability and other doesn’t

Ex: experimental subjects can either get worse or better while control subjects show no change

100
Q

What do you do if your baseline measurements aren’t stable?

A

Extend length of time for baseline data collection until it becomes stable, control for variables which may cause instability, use design that doesn’t require baseline measurement (alternating treatment designs)

101
Q

What is a time series design?

A

Most single subjects are variants, multiple measurements of DV take place prior to and after IV is introduced

102
Q

What is a withdrawal design (ABAB)?

A

Baseline taken prior to introduction of IV, IV is then introduced and more measurements taken, IV is taken away and more measurements taken, can repeat multiple times

103
Q

What does A and B stand for in withdrawal designs?

A

A= Baseline/Withdrawal phase

B= Manipulation/Intervention Phase (IV present)

104
Q

What do the letters in the ABAC design?

A

A = Baseline/Withdrawal (No IV)

B = 1st manipulation/Intervention (1st IV Present)

C = 2nd Manipulation/Intervention (2nd IV present)

105
Q

What do the letters in a ABCB design stand for?

A

A = Baseline/Withdrawal (No IV)

B = Manipulation/Intervention (IV Present)

C = Placebo/Control Intervention

106
Q

What is reversal design?

A

When intervention is withdrawn, replaced with interaction which produces opposite effect

Ex: Two siblings play aggressively with one another and there is concern it is due to receiving attention (negative) from parents when play is aggressive

107
Q

What is alternating treatments (between-series designs)?

A

Variation of ABAB, 2 diff. Interventions/treatments alternated with one another, order can be random or systematic, baseline measurements not required

108
Q

What is a multiple baselines design?

A

All previous examples assume that there are no lasting effects of the treatments/interventions, no withdrawal phase in this study design, effect of treatment on two or more behaviors is assessed OR effect of a treatment on single behavior assessed across multiple situations

109
Q

What is an example of multiple baselines: multiple situations?

A

Smoking at work and home (morning and evening)

110
Q

What is multiple baselines: multiple measures?

A

Child who whines, bickers, and talks back to parent

111
Q

What is internal validity in single subject designs?

Behavior of an individual

129
Q

130
Q

What is scientific misconduct?

A

Plagiarism, fabrication of data, or falsification of proposing, conducting, reviewing, or reporting of research

131
Q

What are the problems with group comparison studies?

A

Prompts ethical concerns among those who wish to assess the effectiveness of a treatment, pose practical problems to identifying and soliciting cooperation of large enough sample, and criticism of averaging across participants in group comparison studies

132
Q

What is an advantage of a single subject design over a group design?

A

Can determine effectiveness of treatment for a specific individual, replication of study can see how well treatment can be generalized

133
Q

What is the primary logic behind a single subject design?

A

Compare behavior after intervention with baseline of that behavior

134
Q

What does a research have to establish to detect a difference between baseline and intervention measurements?

A

Stable baseline (baseline with little variability)

135
Q

What does a stable baseline have?

A

Little variability (can control by controlling source of variance), and it does not increase or decrease

136
Q

When are increasing or decreasing baselines problematic?

A

When the baseline is going in the direction that the research predicted after he manipulation of the IV occurs

137
Q

When is the increasing or decreasing of a baseline less of a concern?

A

When the trend is going in the opposite direction of the expected effect of the IV

138
Q

What design are many single subject designs variations of?

A

Time-series design (several measurements before and after intro. Of IV)

139
Q

What exactly is ABAB design?

A

Baseline (A), followed by intervention (B), followed by withdrawal (A), and then again intervention (B)

140
Q

What exactly is an ABAC design?

A

B introduced after baseline, B is withdrawn to return to baseline (A), second intervention C is introduced

141
Q

What is a placebo effect?

A

Behavior changes after introduction of intervention, when intervention is known to be ineffectual

142
Q

What exactly is a ABCB design?

A

After baseline, B intervention is introduced and then replaced by placebo (C), B intervention is then reintroduced

143
Q

What is a reversal design?

A

New and opposite intervention is introduced

144
Q

What is the difference between the alternating-treatments design and ABAB design?

A

Alternating-treatments design does not require a baseline, and two (or more) treatments are presented instead of only one

145
Q

What can a multiple-baselines design be used for?

A

Measure effect of intervention on different behaviors, effect of treatment on two or more behaviors, or treatment on single behavior across two or more sitations

146
Q

What two designs avoid withdrawing treatment?

A

Changing-criterion design and multiple-baselines design

147
Q

Why is mail and internet surveys being self-administered a benefit?

A

Can be administered widely, less susceptible to sampling bias, little opportunity for interviewer bias, good for collecting information that person might not want to talk about in person or over the phone
