2-Standard celeration chart and applications Flashcards
Inductive versus deductive
Intimate CONTACT with phenomenon of interest such as:
Biology
Chemistry
Physics
Focus:
Observable behavior
objective, operational definitions
Involves use of:
standard, absolute units of measurement
Experimental analysis
Identification of functional relations
Natural Science of Behavior
Standard Units
Everyone uses them
Absolute Units
VALUE does NOT change from one instance to the next
Universal Units
Apply to every instance
Dimensional QUANTITY of behavior: Entailed in the behavior itself Not an abstraction Sensitive to changes in the independent variable Visible to the naked eye!
Units of Measurement- Natural science of behavior
Count
-Repeatability Or Countability
Time
- Behavior occurs in time - Behavior takes time to occur
Properties of Behavior
Derived from the fundamental properties of behavior:
- Frequency/rate (count/time) - Latency (temporal locus) - Duration (temporal extent) - Celeration (count/time/time) - Inter-response Time
Dimensional Quantities of Behavior
Abstractions from behavior of interest
Statistics-
Percent correct, ratios, Likert Scales
Insensitive to environmental variables
Dimensionless Quantities
Utilized Natural science of behavior
Focused on:
Free -operant responding (Operant chamber)
Rate of response as a measure of behavior
Standard graphic display (Cumulative record)
Because of these things, was able to make the DISCOVERIES he did.
B.F. Skinner
Can be emitted any time
Discrete
Do not require much time for completion
Produce a wide range of response rates
Ex. Key pecks and lever presses
Free operant responses
Dimensional unit of behavior that is defined as count/Time
Sensitive to settle manipulations of the independent variable Such as: schedules of reinforcement Stimulus control Procedures Extinction
Rate of response
A standard graphic display that reflects a ratio of count over time
Provides an ongoing, continuous recording.
Standard slopes are produced that are represented as frequency/rate of responding, thus allowing ease of interpretation and comparison
Cumulative record
A student of BF Skinner
Commitment was to put the same analytic tools into the hands of teachers/practitioners, such that discoveries could be made
To this end, created the Standard Celeration Chart, SCC
Og Lindsley
Lowest point is at .001 (1000 minutes). This represents one Occurrence of behavior in a single DAY.
Highest point is at 1000 and a depicts a behavior occurring 1000 times per minute
Celeration is change in rate over time.
Count/minute/day/week
Bottom axis = successive calendar days with THIN Vertical lines = Individual weekdays
Top axis = successive calendar week With Sunday = thick vertical lines.
Column between two Sunday lines is one calendar week.
Bottom left Is a standard Celeration fan-Depicts standard slopes and allows you to compare and achieved slope with the standard slope.
On right = a cheat sheet of time periods of chart.
Standard Celeration Chart
1) Counting Time Floor : Observation, recording period
- Formula: 1/number of minutes spent recording.
2) Frequency Correct
3)Frequency Incorrect
Find where Day Line and Frequency Line Intersect
Chart at Intersection
Apply is mainly to acquisition targets. Ex,. Number of words read correctly and monitor words read incorrectly.
Deceleration Target, may not have fair pair
Creating a complete daily record:
Dropping timing. Reflects longer and longer Timing. And is treated with a dash on the line that intersects at the day and the frequency line for your timing floor
Standard celebration chart
Using a standard absolute unit of measurement: Count per minute.
Even if we are recording longer it still count per minute
Standard celebration chart: charting frequencies
Change in RATE over time
Ex. Count/ minute/day/week
Celeration
Human behavior changes EXPONENTIALLY. Via Multiplication and Division
Y axis Allows us to predict human behavior more accurately because logarithmic nature of SCC Provides better representation of human behavior and changes in behavior than can be captured on traditional equal intervals line graph
Different than equal interval line graphs, which move up and down y-axis via addition and subtraction (by factor 1).
Left vertical axis different than most traditional graphs. One Moves up the access via MULTIPLICATION and Down via division. = logarithmic nature of chart
Bottom left standard Celeration Fan; Depicts standard slopes and allows comparison of achieved slope with standard
Right: cheat sheet of time Periods for chart
Standard celebration chart- first member of family of charts
Enables looking at Weekly Changes
Along bottom- Successive Calendar weeks
- Thin vertical lines represents a single week
Top- Calendar Months. Each Column = month
Weekly Chart- second member of family of charts SCC
Bottom- Success of calendar months
Top- Years
Thin line- Single Month
Bold Lines: Years
Monthly Chart- Third member family SCC
Across Bottom = Successive calendar months
Across Top= Decades
Yearly chart- last (4th) member SCC
Axis
Slopes
Unit of measure
Standard on the SCC
Standard Behavior Chart
6 Cycle Chart- has Six COUNTING CYCLES of 10
Other names used for the SCC
The slope of a celebration line at a given value (Eg x2 celeration) will be the same regardless of where the baseline behavior occurred. That is, proportional amount of behavior change are preserved regardless of starting frequency
The relationship between starting frequency and equivalent slopes
Frequency lines on the chart are not counted by the same interval all the way up the chart.
County starts with ones, 123…But at 10 the counting interval changes to 10 i.e., 10, 20, 30.
It again changes at 100.
The jingle describes how to count up the Y –axis:
The B___. Number on the left, that starts with one, tells you what to count B____. And we are to count F____.
Counting along the Y axis
depicts standard slopes
Allows for quick comparison
Standard celeration fan
The slope of a celebration line at a given value e.g., X 2 Celeration , will be the same regardless of where the baseline behavior occurred.
That is, proportional amount of behavior change our preserved regardless of starting frequency.
Relationship between starting frequency and equivalent Slopes
Equal interval graphs do not use a standard data display, unit of time or measurement
problematic because you must always orient your audience and yourself to each unique graph.
Slopes are inflated as you MOVE up the scale.
Baseline frequencies are a Letter CONFOUND Which makes it difficult to analyze the intervention
Problems with equal intervals line graph
