, , , ,

Ratio schedules

involve reinforcement after a certain number of responses have been emitted

. … Interval schedules involve reinforcing a behavior after an interval of time has passed. In a fixed interval schedule, the interval of time is always the same.

What is the main difference between a ratio schedule and an interval one?

Interval means the schedule is based on the time between reinforcements, and ratio means the schedule

is based on the number of responses between reinforcements

. Reinforcement is delivered at predictable time intervals (e.g., after 5, 10, 15, and 20 minutes).

What is the difference between interval schedules and ratio schedules quizlet?

ratio schedules favor short inter-response times. interval schedules

favor long inter-response times

. two schedules are in effect at the same time and the subject is free to switch from one response key to another.

What is an example of interval schedule?


Your Employer Checking Your Work

: Does your boss drop by your office a few times throughout the day to check your progress? This is an example of a variable-interval schedule. These check-ins occur at unpredictable times, so you never know when they might happen.

What are the two types of interval schedules?

Two types of interval reinforcement schedules may be used:

fixed interval and variable interval

.

What is the key to distinguishing between ratio and interval schedules between fixed and random schedules?

In a variable schedule the number of responses or amount of time between reinforcements change randomly. The schedule is unpredictable. In a ratio

schedule reinforcement

occurs after a certain number of responses have been emitted. Interval schedules involve reinforcing a behavior after a period of time has passed.

Why do ratio schedules produce higher rates of responding than interval schedules?

-why do ratio schedules produce higher rates of responding than interval schedules? … -in a ratio schedule

there are no time constraints and the faster the participant completes the ratio requirement

, the faster they will receive the reinforcer.

What is the purpose of using a variable ratio schedule of reinforcement?

The purpose of using a variable ratio schedule of reinforcement is to :

Eliminate the predictability of reinforcement

.

What does variable ratio mean?

In operant conditioning, a variable-ratio schedule is

a schedule of reinforcement where a response is reinforced after an unpredictable number of responses

. … Gambling and lottery games are good examples of a reward based on a variable ratio schedule.

What is ratio strain ABA?

:

The appearance of pauses in VR responding

, or in FR responding at times other than after a reinforcer (cf. POSTREINFORCEMENT PAUSE); a result of large ratio size and/or low reinforcement frequency.

What does fixed ratio mean in psychology?

In operant conditioning, a fixed-ratio schedule is

a schedule of reinforcement where a response is reinforced only after a specified number of responses

. Essentially, the subject provides a set number of responses and then the trainer offers a reward.

Why is variable ratio the most effective?

Variable ratios

In variable ratio schedules, the individual does not know how many responses he needs to engage in before receiving reinforcement; therefore, he will continue to engage in the

target behavior

, which creates highly stable rates and makes the behavior highly resistant to extinction.

What are fixed ratios?

Fixed ratio is

a schedule of reinforcement

. In this schedule, reinforcement is delivered after the completion of a number of responses. The required number of responses remains constant. … This ratio requirement (number of responses to produce reinforcement) is conceptualized as a response unit.

What do you mean by reinforcement describe the different schedules of reinforcement?

Schedules of reinforcement are

the precise rules that are used to present (or to remove) reinforcers (or punishers) following a specified operant behavior

. These rules are defined in terms of the time and/or the number of responses required in order to present (or to remove) a reinforcer (or a punisher).

How do different reinforcement schedules affect behavior?

How do different reinforcement schedules affect behavior? –

Continuous reinforcement rapid learning occurs, but extinction occurs quickly too

. -Partial reinforcement sometimes reinforced, sometimes not; learning is slower but resistance to extinction is greater. … Punishment teaches discriminating behavior.

What is a fixed ratio schedule of reinforcement quizlet?

Fixed Ratio:

There is a fixed number of responses necessary to produce reinforcement

. 2. Variable Ratio: Set average value of fixed number of responses, so average on every 5th (for example) behavior, varies slightly. … Fixed Interval: Reinforce the first response after passage of fixed amount of time.

What are the four partial schedules of reinforcement and how do they differ?

There are four types of partial reinforcement schedules:

fixed ratio, variable ratio, fixed interval and variable interval schedules

. … This is the schedule where a response is reinforced after an unpredictable number of responses.

Do ratio schedules have higher response rates than interval schedules?

Classical conditioning occurs with ratio schedules whereas instrumental conditioning occurs with interval schedules. … Higher response rates occur with ratio schedules than with interval schedules.

What is the difference between continuous and intermittent reinforcement?

A continuous schedule of reinforcement (sometimes abbreviated into CRF) occurs when reinforcement is delivered after every single target behaviour whereas an intermittent schedule of reinforcement (INT)

means reinforcement is delivered after some behaviours or responses but never after each one

.

Why might a researcher use a variable ratio of reinforcement rather than a fixed ratio?

Why might a researcher use a variable ratio of reinforcement rather than a fixed ratio? … Variable ratio schedules of reinforcements allow researchers to use both classical and operant conditioning. E.

Variable ratio schedules of reinforcement are more resistant to extinction than fixed schedules

.

Which schedules are least resistant to extinction?

Among the different types of reinforcement schedules, the variable-ratio schedule (VR) is the most resistant to extinction whereas

the continuous schedule

is the least

​ 7 ​

.

Which schedule produces the highest rates of responding?


Variable-ratio schedules

occur when a response is reinforced after an unpredictable number of responses. This schedule creates a high steady rate of responding.

What is the difference between variable interval and variable ratio?

Variable ratio schedules maintain

high and steady rates

of the desired behavior, and the behavior is very resistant to extinction. Interval schedules involve reinforcing a behavior after an interval of time has passed.

What is DRL procedure?

Differential Reinforcement of Low Rates of responding (DRL) is a

procedure in which the implementer can lower the rate of a response by reinforcing fewer incidents of that response

or by reinforcing longer time intervals between incidents of the response.

What are the two forms of ratio schedules psychology?

There are two major types of ratio schedules.

A Variable Ratio Schedule produces rewards

irregularly. Thecriteria for reinforcement changes, it rotates around an average number ofresponses. The amount of work required per reinforcement varies somewhatrandomly within certain limits (Carpenter, 1974).

What is fixed interval schedule?

A Fixed Interval Schedule

provides a reward at consistent times

. Forexample a child may be rewarded once a week if their room is cleaned up. Aproblem with this type of reinforcement schedule is that individuals tend to wait until the time when reinforcement will occur and thenbegin their responses (Nye, 1992).

What is ratio and interval?


Interval scales hold no true zero and can represent values below zero

. For example, you can measure temperature below 0 degrees Celsius, such as -10 degrees. Ratio variables, on the other hand, never fall below zero. … Ratio scales differ by having a character of origin, which is the starting or zero-point of the scale.

Is a schedule of reinforcement in which every correct response is reinforced?


Continuous reinforcement

occurs when each and every correct response is followed by a reinforcer. … This is called the partial reinforcement effect. In a fixed ratio schedule of reinforcement, a certain number of responses are required before reinforcement is given.

What are the four types of intermittent reinforcement schedules?

There are four types of intermittent schedules that you can use in order to maintain the behavior; 1) fixed ratio, 2) fixed interval, 3) variable ratio, and 4) variable interval. Fixed Ratio: In a fixed ratio (FR) schedule, a specific or “fixed” number of behaviors must occur before you provide reinforcement.

What is schedule thinning in ABA?

6. Introduction. Schedule thinning is a term used to

describe a variety of techniques for decreasing, or

.

“thinning

,” an existing schedule of reinforcement by gradually increasing the response ratio or. the duration of the time interval (Cooper, Heron, & Heward, 2007).

What does stretching the ratio mean?

What does the term “stretching the ratio” mean and how should it be carried out? a. Increasing “

stretching” amount of responses before reinforcement

. Goes from a rich to a lean schedule.
