Extinction in behavior
Define and give example |
|
Definition
when a behavior is conditioned with reinforcement and then the reinforcement stops, the behavior will gradually disappear.
Palov's dogs-salivate at bell with anticapation of food( bell= food many times), bell ring (no food), continue bell no food, gradually stop salivating |

Definition
| Can be used to control the random variation of two factors. The design is arranged with an equal number of rows and columns, so that all combinations of possible values for the two variables can be tested multiple times. This design is used to reduce the effect of random or nuisance factors. |

Definition
| use variable ratio schedules of reinforcement. This is variation of reinforcment generally ensures a more persistent behavior |

LSD Rats-what happened?
What technique? |
|
Definition
Jarrad-trained rats to press lever for food
LSD given to determine the effect on rate of pressing lever
six levels of independent variable
0, .05,.10, .20, .40, .80
2 smallest enhanced speed and 2 highest severely impaired speed
could have caused carry over effect
Within-subject design |

| experiment designed to show the effect stress caused ulcers. Monkeys were tested to see would responded more quickly to press button to avoid shock. These were taken and given the label as "executive". These monkeys then would be placed with another monkey "coworker". Both mmonkeys receiveed periodic shocks over a 4 hour period. The executive was given the option of pressing a button to avoid a shock. If this monkey failed to do so often enough not only would they be shocked but their coworker monkey would also be shocked. This was considered by the experimenters as a "high stress work environment". Results found that the executives suffered from severe ulcers when their coworkers had no obvious diorders. |

Term
| Problem of Scale Attenuation |
|
Definition
Ceiling effects-upper limit of the scale
Floor effects-bottom of the scale
determining the effects of dependent variables in an experiement when performance exceeds the the limitations of the measurement scale. Be wary of scale and task |

Term
| Critical Control in Between-Subjects Factorial Design |
|
Definition
| Randomly selection of subjects is not always possible therefore random assignment to conditions is critical. Random-groups design: unbiased assignment of subjects to conditions |
|
|
Term
| Difference between AB & ABA (reversal design) |
|
Definition
AB-A is baseline condition and B is the condition after intro of therapy
Poor design. No way to measure if therapy caused changes or if confounding variable did.
ABA- second A is designed to rule out confounding vavriables. when subject returns to their original baseline, if the behavior returns, then the experimenter can conclude that the independent variable (B) is what effected change.
