Q

S1 Noise guard

A
  • like a microphone set up on the ceiling to track noise levels
  • noise above 500Hz would activate it (length)
  • recorded the umber of events over the threshold (in 10ths of seconds)
  • threshold 93dB

A

lights, music, raffles
-firsst day experimenter explained:
Lights on when too loud
Music on first day all times, after only when noise was low
Raffle for hamburger coupons each day if cut off criterion was not exceeded (previous day)
-students could make music suggestions
Raffle for 10 movie passes after 5 consecutive days
If one student intentionally turned on lights they would be reported to the principle

Driver told to do the same

A

This experimental condition was conducted identically with that of Experiment 1. Treatment (lights and preferred music). The treatment procedure was introduced and con- ducted in the same manner described in Ex- periment 1 except that no raffles were available. In addition, the cutoff criterion was reduced more gradually in this experiment.

50
Q

P3 conclusions

A

can be applied to Ind/grp and easily.

51
Q

H purpose

A

find effective method to load horses using R+ not aversive procedures
-horse fighting loading can be dangerous

52
Q

What is meant by the criterion of evaluation?

A

What will be the standard of proof that the independent variable actually influences behavior? Kazdin delineates between two possible criteria: experimental and therapeutic.

53
Q

What is meant by experimental criteria?

A

The use of an experimental criterion signifies a reliable or veridical difference in behavior under experimental conditions. When using statistical procedures to evaluate an intervention, this criterion is intuitively labeled statistical significance.

54
Q

What is meant by therapeutic criteria?

A

A therapeutic criterion signifies the clinical significance of any observed differences induced by the independent variable (Kazdin, 1999). This criterion is tantamount to asking, is the effect meaningful to the patient?

Applying these two criteria then, an intervention may reliably diminish a problematic behavior (experimental criterion), yet only to the degree that has very little benefit to the individual’s life (lack of therapeutic criterion). Ideally, the analyst will consider both the experimental (statistical) and therapeutic (clinical) significance of any selected criterion that is used to draw conclusions about a conducted intervention.

55
Q

What is visual inspection?

A

Visual inspection is looking at the graphed data to determine next steps?

56
Q

What is statistical analysis?

A

collecting and scrutinizing every data sample in a set of items from which samples can be drawn

57
Q

What is continuous time-series?

A

Continuous time series involves uninterrupted collection of observations.

58
Q

What is discrete time series

A

A discrete series is one in which the observations are made at equal intervals in time, with the intervals between observations remaining constant throughout the observation period.

59
Q

What is “shock”?

A

unique influences that drive data up or down its mean level at the time.

60
Q

What is autocorrelation?

A

When observations of a phenomenon are collected repeatedly over time, subsequent observations tend to be more related than observations more temporally distant

61
Q

What is non independence?

A

when observations are not independent, observations close together in time become predictive of one another. This nonindependence creates data structures that when described linearly, produces residuals, or error terms, that are correlated.

62
Q

What is lag 1?

A

Lag 1 correlation represents the degree to which the current observation can be predicted from the observation prior. It would be calculated by correlating the second observation with the first observation, the third with the second, and so on throughout the series.

63
Q

H purpose

A

The purpose of the present study was to develop and validate a program based on principles of positive reinforce- ment, as well as to create a fast and safe way to get horses to ‘‘self-load.’

64
Q

H define self loading

A

Self-loading was defined as the trainer being able to walk the horse to the trailer, toss the lead rope over its back, say ‘‘step up,’’ have the horse walk into the trailer, and stand still long enough for the trainer to latch the butt chain and close the trailer door.

91
Q

A

looking at the autocorrection over the past 10 data points.

92
Q

What is serial dependency

A

serial dependence if the value at some time t in the series is statistically dependent on the value at another times.

93
Q

What are the 3 limitations of t test and F test

A
  • these tests are robust in terms of normality
  • assume obs in each phases are independent (no AC)
  • insensitive to trends that occur within a phase
94
Q

What is randomization

A

it is assumed that exp conditions are randomly assigned

95
Q

What is alternation randomization

A

randomly assigns the intervention to given observations using predetermined limitations

96
Q

What is phase randomization

A
  • intervention is optimally introduced over the course of several measurement occasions occurring in a predetermined order.
  • commonly used when interventions are predicted to have a carry over effect
97
Q

What is meant by abrupt or gradual onset

A

quick or slow. Matched with duration

98
Q

What is meant by permanent or temporary duration

A

Matched with onset type.

99
Q

What is change in level

A

a comparison between the ending value of phase 1 and the starting value phase 2

100
Q

what is change in slope

A

a linear rate of change.

101
Q

What is a celeration line

A

The Overall celeration describes all of the frequencies charted, regardless of cycles, trends, periods, or event manipulations. An Overall celeration runs as a single line of best fit through all of the frequencies.

102
Q

What is meant by replication is at the heart of any science

A

replication serves at least 2 purposes:

  • Reliability of findings – can others get similar results with same procedures
  • Generality of findings- do you get similar results under different conditions
  • Interrelated, every time you get generality you also get reliability
103
Q

What is direct replication

A

-Replication of a given experiment by the same investigator

Repetition of the experiment on the same subject – across behaviors for example
Repetition on different subjects – same procedures applied to different subjects

104
Q

How is replication related to generality

A

.

105
Q

What is simultaneous replication

A

Useful when intervening with a coexisting group

Number of subjects treated simultaneously in a particular experimental design, plot individual data

106
Q

What are the guidelines for direct replication

A
  • Therapists and settings constant
  • Behaviour topographically similar across subjects
  • Client background variables closely matched (homogeneity)
  • treatment should be uniform (unless failure)
  • 1 ex, 3 rep are sufficient
  • still doesn’t provide broad generality but enough to work with
107
Q

What is systematic replication

A

Replicate findings from a direct replication series varying settings, behavior change agents, behavior disorders, or any combination thereof.

Provides further information on generality of findings across clients because new clients are usually included

108
Q

Why are failures important

A
  • determine cause of intersubject variability

- continued research

109
Q

What are the guidelines for systematic replication

A
  • should start with sound direct replication
  • change 1-2 variables
  • is a search for failures, if none then continue
  • When is it over, never over
110
Q

What is clinical replication

A

Replication in which a treatment package containing two or more distinct procedures is applied to a succession of clients with multiple behaviors, i.e. “parenting package”

Field Testing

111
Q

What is benchmarking

A

Treat clients in naturalistic treatment settings with a treatment program

112
Q

What are practice research networks

A

Networks that assemble an infrastructure that involves the collaboration of clinical researchers and full time practitioners expressly to examine the generalization and ability to disseminate newly developed treatments

113
Q

What are 4 reasons why replication continues

A
  • Decentralized – not just doing same big Ex over and over, do smaller ones
  • Professional reinforcement
  • Close to clinic – client receives treatment
  • Series are cumulative
114
Q

lag

A

past values
