BHSC 1000 Ch. 2 Terms

The period during which the target behaviour is recorded before treatment is implemented

Measurement of the target behaviour (or behaviours) in behaviour modification

Includes action verbs describing specific behaviours that a person exhibits; is objective and unambiguous

The observer observes the client continuously throughout the observation period and records each occurrence of behaviour

Person observes and records target behaviour as it occurs

The total amount of time occupied by the behaviour from start to finish

The number of times the behaviour occurs in an observation period

Observer records the frequency of the target behaviour but does so within consecutive intervals of time in the observation period

Purpose

Involves using interviews, questionnaires, and rating scales to obtain information on the target behaviour from the person exhibiting the behaviour or from others

The amount of force, energy, or exertion involved in the behaviour

When two people independently observe the same behaviour and both record that the behaviour occurred

Along with interrater reliability, another term for an IOA

The time from some stimulus or event to the onset of the behaviour

The behaviour is recorded only if it occurs at the exact instant the interval ends

Consists of the places in which the target behaviour typically occurs

The specific period during which the observer records the target behaviour

The observer scores the interval as an occurrence if the behaviour occurred during any part of the interval

Percentage of trials or percentage correct

An indirect assessment method that can be used when a behaviour results in a certain tangible outcome that you are interested in. Also called permanent product recording

Frequency divided by the time of the observation period

When the process of recording the behaviour causes the behaviour to change, even before any treatment is implemented

The exact time of each onset and offset of the target behaviour is recorded

The client observes and records their own behaviour

The observer arranges for specific events or activities to occur during the observation period

Divide the observation period into intervals of time but observe and record the behaviour during only part of each interval

No specific events or activities are arranged and no instructions are given during the observation period

The occurrence of the behaviour is marked in an interval only when the behaviour occurs throughout the entire interval
