### According to ____, rather than saying that the child's behavior was reinforced by a treat, we should instead say the child's behavior was reinforced by eating a treat.

Premack principle

A schedule in which the response requirement changes as a function of the organism's performance while responding for the previous reinforcer.

### Among the four basic intermittent schedules, fixed schedules are more likely to produce _____ than variable schedules, and ratio schedules are more likely to produce _____ than interval schedules.

post-reinforcement pauses: higher rates of response

ratio strain

### As I look over the menu in a restaurant, I select a cheeseburger rather than spaghetti and meatballs. Both meals are approximately the same portion size and each provides the same caloric value. Which of the following theories is most useful in explaining why I choose one food over another?

incentive motivation

### behavioral bliss point approach

The theory that an organism with free access to alternative activities will distribute its behavior in such a way as to maximize overall reinforcement.

### chained schedule

A schedule consisting of a sequence of two or more simple schedules, each with its own SD and the last of which results in a terminal reinforcer.

### A chained schedule ends in a(n)

terminal reinforcer

### complex schedule

A schedule consisting of a combination of two or more simple schedules.

### conjunctive schedule

A type of complex schedule in which the requirements of two or more simple schedules must be met before a reinforcer is delivered.

### continuous reinforcement schedule

A schedule in which each specified response is reinforced.

DRP

### differential reinforcement of high rates (DRH)

A schedule in which reinforcement is contingent upon emitting at least a certain number of responses in a certain period of time—or, more generally, reinforcement is provided for responding at a fast rate.

### differential reinforcement of low rates (DRL)

A schedule in which a minimum amount of time must pass between each response before the reinforcer will be delivered—or, more generally, reinforcement is provided for responding at a slow rate.

### differential reinforcement of paced responding (DRP)

A schedule in which reinforcement is contingent upon emitting a series of responses at a set rate—or, more generally, reinforcement is provided for responding neither too fast nor too slow.

### DRH stands for

Differential reinforcement of high rate of behavior

### drive reduction theory

According to this theory, an event is reinforcing to the extent that it is associated with a reduction in some type of physiological drive.

### fixed duration (FD) schedule

A schedule in which reinforcement is contingent upon continuous performance of a behavior for a fixed, predictable period of time.

### fixed interval (FI) schedule

A schedule in which reinforcement is contingent upon the first response after a fixed, predictable period of time.

### fixed ratio (FR) schedule

A schedule in which reinforcement is contingent upon a fixed, predictable number of responses.

### fixed time (FT) schedule

A schedule in which the reinforcer is delivered following a fixed, predictable period of time, regardless of the organism's behavior.

### An FR 50 schedule of reinforcement is ____ than an FR 10 schedule.

More lean

An increase in the strength and/or efficiency of responding as one draws near to the goal.

### If an animal is unable to reach its behavioral bliss point, it will

distribute its behavior to draw as close to it as possible

FD

DRL

### In a chained schedule, the consequences for the early behaviors in the chain function as ____ that also serve as ____ for the next behavior.

secondary reinforcers; discriminative stimuli

### incentive motivation

Motivation derived from some property of the reinforcer, as opposed to an internal drive state.

### intermittent (or partial) reinforcement schedule

A schedule in which only some responses are reinforced.

### In you check yoru phone to see if you have text messages, you sometimes have one. You can't make text messages faster by checking more frequently! Which of the following schedules of reinforcement fits this example?

Variable interval

variable ratio

### noncontingent schedule of reinforcement

A schedule in which the reinforcer is delivered independently of any response.

fixed

ratio strain

### The pigeon must turn circles continuously for an average of 10 seconds in order to earn access to food. This is an example of a _____ schedule

variable duration

### Premack principle

The notion that a high-probability behavior can be used to reinforce a low-probability behavior.

### ratio strain

A disruption in responding due to an overly demanding response requirement.

### response deprivation hypothesis

The notion that a behavior can serve as a reinforcer when: (1) access to the behavior is restricted and (2) its frequency thereby falls below its preferred level of occurrence.

### response-rate schedule

A schedule in which reinforcement is directly contingent upon the organism's rate of response.

### schedule of reinforcement

The response requirement that must be met to obtain reinforcement.

noncontingent

drive; incentive

### This schedule produces a moderate, steady rate of response with little or no post-reinforcement pause.

Variable Interval

### variable duration (VD) schedule

A schedule in which reinforcement is contingent upon continuous performance of a behavior for a varying, unpredictable period of time.

### variable interval (VI) schedule

A schedule in which reinforcement is contingent upon the first response after a varying, unpredictable period of time.

### variable ratio (VR) schedule

A schedule in which reinforcement is contingent upon a varying, unpredictable number of responses.

### variable time (VT) schedule

A schedule in which the reinforcer is delivered following a varying, unpredictable period of time, regardless of the organism's behavior.

### What the dog has to do in order to get fed is an example of

schedule of reinforcement

behavioral bliss

### Yesterday morning at the bus stop, Joseph just happened to be leaning against the bus stop sign when the bus finally arrived. This morning, Joseph spent a lot of time learning against the sign. This seems to be an example of a(n) ____ behavior that has been reinforced on a(n) ____ schedule

superstitious; VT
