Question 1

A quantifiable aspect of a natural phenomenon is called a(n)

Accepted Answer

B

Question 2

All of the following are dimensions of individual responses, except:

Accepted Answer

Frequency is a measure of how often an event occurs, while duration, count, and latency are all measures of time.

Question 3

Each of the following statements describe why it is important to carefully select dimensions of behavior for measurement, except:

Accepted Answer

This statement is incorrect as multiple dimensions can be chosen for investigation, depending on the needs of the research question and context. The other statements are correct and highlight the importance of careful selection of dimensions for accurate and meaningful measurement of behavior.

Question 4

Dimensional measurement involves:

Accepted Answer

Dimensional measurement involves quantifying a specific dimension with a numerical value. It can be length, width, mass, time, or any other measurable aspect, and the numerical value assigned represents the amount or extent of that dimension that was observed or measured. Option B describes longitudinal research, option C refers to labeling, and option D describes comparative analysis. None of these options capture the essence of dimensional measurement.

Question 5

Each of the following are dimensions of multiple responses, except:

Accepted Answer

Count is not a dimension of multiple responses; it is a simple tally of occurrences, whereas the other options involve time or rate aspects.

Question 6

Locating individual responses in time with reference to other events is reflected by the dimensional quantity of

Accepted Answer

Latency refers to the time between the occurrence of a stimulus and the resulting response. It is a measure of how quickly the individual responds to a stimulus and allows for the precise timing of events in research. Duration refers to the length of time that a response or stimulus lasts. Frequency refers to how often an event or behavior occurs. Topography refers to the physical characteristics of a response, such as its shape or form. While all of these dimensions may be important for understanding behavior, only latency specifically refers to the timing of events.

Question 7

Lisa is a practitioner working with a child who has difficulty transitioning from one activity to the next. She is interested in improving the child's delay between being told to switch activities and starting the next activity. Which of the following dimensions would be most important for her to measure?

Accepted Answer

Latency is the time between the presentation of a stimulus and the start of a behavior, so measuring the latency between being told to switch activities and starting the next activity would be the most important dimension to improve the child's transition skills. Interresponse time, frequency, and count are measurements that may not be as relevant in this situation.

Question 8

Cam is recording how much time it takes his client to complete 20 multiplication problems. Cam is recording what dimension of behavior?

Accepted Answer

Duration refers to the length of time that a behavior occurs. In this case, Cam is measuring how long it takes his client to complete a specific task (20 multiplication problems), which falls under the category of duration.

Question 9

What is the unit of measurement for countability?

Accepted Answer

Countability is the measure of the number of times an event occurs. The unit of measurement for countability is the cycle.

Question 10

Which of the following is a limitation of what duration describes about behavior?

Accepted Answer

Duration inherently includes temporal dimensions since it measures the length of time a behavior occurs, making options B and D incorrect. It is not limited to lab settings, as duration can be measured in various environments, making A incorrect. The correct answer is C because duration focuses on how long a behavior lasts without necessarily accounting for the number of occurrences of that behavior, which is what "countability" refers to.

Question 11

Which of the following is a limitation of what countability describes about behavior?

Accepted Answer

Countability does not specify any temporal dimensions, meaning it only provides a total count of occurrences without indicating when they happen or how frequently they occur over time.

Question 12

You are working with a 4th grader, Sally, who has difficulty reading. One of the measures you use to evaluate your interventions is to record the amount of time between finishing reading one word in a sentence and starting to read the next word. This is a measure of:

Accepted Answer

Interresponse time is the time between the end of one response and the beginning of the next response. In this case, the response is reading one word and the next response is reading the next word. Therefore, measuring the time between them is an interresponse time.

Question 13

In the study of behavior, measures of frequency generally take the form of the ratio:

Accepted Answer

Measures of frequency in behavior usually involve counting the occurrence of a particular behavior within a specified period of time, making choice B the best answer. The other choices are not relevant or do not make sense in the context of measuring the frequency of behavior.

Question 14

To calculate the frequency of responding, researchers can divide the total count of responses by each of the following, except:

Accepted Answer

Total celeration is not used to calculate frequency of responding. Frequency is typically calculated by dividing the total count of responses by the total time behavior was observed or the total session time. Interresponse time is related to the time between responses, not frequency.

Question 15

The most common approach to calculating rate or frequency is to divide total count by

Accepted Answer

Dividing the total count by the total time behavior was observed gives the rate or frequency of the behavior. Total interresponse time (A) and total duration (C) are not appropriate for calculating frequency. Total celeration (D) is a measure of the changes in frequency over time, not the frequency itself.

Question 16

How is celeration related to frequency?

Accepted Answer

Celeration is a measure of how quickly behavior changes over time. It is calculated by determining the ratio of a behavior's frequency in one period of time (e.g. one week) to its frequency in another period of time (e.g. the previous week). Therefore, celeration is directly related to frequency as it measures changes in frequency over time.

Question 17

While ratios are valuable ways of looking at data, they can be limiting. In what way can a ratio be limiting?

Accepted Answer

Ratios can obscure the individual values of the numerators and denominators that make up the ratio. This can make it difficult to understand the underlying data and potentially mask important information.

Question 18

When selecting dimensional quantities to measure, a researcher or practitioner should take into consideration each of the following, except:

Accepted Answer

How long one plans on collecting data is not relevant to the selection of dimensional quantities. All other options are important considerations.

Question 19

A dimensionless ratio is a unitless number that results from calculations whose components share the same:

Accepted Answer

A dimensionless ratio is a number that doesn't have any units because it's derived from dividing two quantities with the same dimensions, for example, length/length, volume/volume or mass/mass. The resulting ratio is therefore dimensionless.

Question 20

When selecting dimensions of behavior to measure, the measures should be guided by each of the following, except:

Accepted Answer

The experimental hypothesis is not a factor that should guide the selection of dimensions of behavior to measure. The experimental question, target behavior, and intervention procedure are all factors that should be considered when selecting dimensions of behavior to measure.
