Asking what contributes more to human behavior, nurture or nature is like asking what contributes more to the area of a rectangle, its width or length.
Ebbinghaus, circa 1885
![Page 4: Bio-Behavioral Approaches to the Assessment and Treatment of Autism](https://reader036.fdocuments.in/reader036/viewer/2022070410/568145b7550346895db2bd63/html5/thumbnails/4.jpg)

Structural vs. Functional Diagnosis
Structural Approach
1. How often a particular set of symptoms
or responses cluster or covary.
Functional Approach
1. Whether and which environmental
variables influence the response.
![Page 5: Bio-Behavioral Approaches to the Assessment and Treatment of Autism](https://reader036.fdocuments.in/reader036/viewer/2022070410/568145b7550346895db2bd63/html5/thumbnails/5.jpg)

Functional Analysis
Identifies the environmental contexts in
which aberrant behavior is likely and
unlikely.
Identifies the consequences that
reinforce and maintain the behavior.
Used to prescribe effective treatments.

Direct Observation
"There are three principal means of
acquiring knowledge. . . observation of nature,
reflection, and experimentation. Observation
collects facts; reflection combines them;
experimentation verifies the result of that
combination."
1. Denis Diderot (1713-1784)

maintained by automatic reinforcement.

Pica (cont’d.)
The risk of death associated with pica
may be higher than that for other forms of
self-injurious behavior (Foxx & Livesay,
1984; McLoughlin, 1988).
Death rates associated with pica in
institutions are similar to those associated
with heart disease.

Does Choice Function as a Reinforcement Across Species
Basic research has shown that pigeons prefer having multiple response options to having just one response option, even when the amount of reinforcement (food) and the size of the response apparatus are held constant (Catania & Sagvolden, 1980).

Experiment 1: Does Choice Function as Reinforcement?
The goal of this study was to
determine whether individuals with
disabilities preferred a choice to a no-
choice condition when each produced
the same terminal reinforcer(s).

The goal of this study was to determine whether individuals with disabilities preferred having more response options (i.e., choice) when having fewer options produced a better tangible reward.

Rapid Cycles and SIB
Rapid-cycling bipolar affective disorder is
defined as the occurrence of at least four
episodes of either mania or depression
within a year.

Estimated Prevalence?
Given independent disorders, the
expected prevalence of the co-occurrence of
profound retardation and bipolar disorder
would be 2 per 1,000,000.
We are seeing many more cases than this
estimate would predict, which suggests that
the disorder may not be independent.

Effects of Environmental Enrichment on Affect and SIB
Candy was a 23-year-old woman with severe
mental retardation, major depression, mild left

Carbamazepine (5.3 mg/kg/day) and a

depression and SIB throughout the day except
when she was left alone.

Forced Normalization and Destructive Behavior in Autism
Force normalization is a term used to
describe a phenomenon in which temporary
