Diagnostic Criteria for ASD
deficits in social communication and interaction, deficits in nonverbal communication, deficits in developing, maintaining and understanding relationships, restricted, repetitive patterns of behavior, interests or activities
Executive Function
Difficulties with planning, thinking ahead, stopping a response, starting another response
mental flexibility
difficulties with changing from one activity/thought to another or changing a routine
weak central coherence
difficulties with synthesizing details or pieces of information into a concept or "big picture."
theory of mind deficits
difficulties with observing others' behaviors, speech, and body language and making an inference about what they are thinking/feeling.
sensory processing differences
some individuals with autism will exhibit challenging behavior if she/he is hypersensitive to sensory experiences
typical development
progression of physical and cognitive skills along an expected path of an average person
atypical development
progression of physical and cognitive skills along a deviated path of an average person
autism spectrum disorder
a neurological disorder that is associated with structural differences in the brain. These neurological differences result in atypical development/performance of social communication and engagement in repetitive behaviors/restricted interests
spectrum of impairments
a conceptual representation of autism symptoms that indicate a gradient of impairments among those diagnosed with the disability. That is, it manifests in different ways of strengths and deficits among those who share the diagnostic label
symbolic play
use of an object/action/idea/person during paly to represent another object/idea/action/person
hidden curriculum
subtle social rules or guidelines that are not directly taught but are assumed to be known.
applied behavior analysis
science of behavior, principles of behavior are applied systematically to improve socially significant behavior
The three-term contingency
a model to analyze behavior that breaks it down into what happens before, during, and after. This is known as the antecedent-behavior-consequence model
operational definition
objective description of the behavior that describes the behavior with specific, observable words. Action verbs that are not interpretable, ensures that data collection is stable across different people
the "dead man's test"
can a dead man do it? def of behavior is objective, measurable, only performable by a living person
positive reinforcement
stimulus change is delivered contingent on behavior, as a result the future probability of the behavior increases. a behavior produces something that benefits a person, and as a result they do it again in the future to get the same benefit. +
stimulus
a thing or event that evokes a specific function reaction
contingent
occurring or existing only if (certain circumstances) are the case; dependent on
negative reinforcement
stimulus change is removed contingent upon a behavior, and as a result the future probability of the behavior increases. A behavior produces the removal of something the person does not like, and as a result the behavior occurs again in the future to remove that stimulus under similar circumstances. +
positive punishment
stimulus change is delivered contingent upon behavior, and as a result the future probability of the behavior decreases. A behavior produces something that makes a persons situation worse, and as a result they do not do it again in the future. -Example: a child hits a child and is spanked by parent, stops hitting.
negative punishment
stimulus is removed contingent upon behavior, behavior decreases in future. -
child hits child to get a toy, parent takes away toy, child stops hitting
categories of behavioral functions
Escape, attention, tangible/activity, sensory
escape
gets ride of aversive stimulus or delays it. Falls to floor when asked to perform difficult task
attention
access to another person's attention, eye contact, facial expression
tangible/activity
preferred item to hold, activity.
sensory
smell, tactile feeling, taste, sound, as a product of engaging in behavior. Rubbing lotion on arms/
determinism
a principle of science that states the universe is a lawful and orderly place
antecedent
stimulus that occur right before the behavior
behavior
anything a person says or does
consequence
a stimulus change that occurs right after the behavior
function of behavior
the purpose that a behavior serves
internal stimulation
sensory
functional assessment
a systematic assessment designed to produce information about what purposes the behavior is serving. 3 types- Functional Analysis (direct), Descriptive analysis (ABC recording), indirect assessment (observation and interview).
functional analysis
direct method of functional assessment that involves systematic manipulation of antecedents and consequences and measurement of a target behavior in order to determine its functions.
descriptive assessment
direct method of functional assessment that involves watching a target behavior and objectively identifying ABC's.
indirect assessment
functional assessment method that does not involve directly watching a person, structured/unstructed interviews.
differential reinforcement
a process by which reinforcement is withheld for a response under certain stimulus condition and delivered for a response under other stimulus conditions
discriminative stimulus
SD a stimulus that signals the availability of reinforcement due to a prior history in which a behavior was emitted in its presence and reinforcement was delivered/produced
neutral stimulus
a stimulus change that neither evokes nor elicits a response
motivating operation
stimulus change in the environment that temporarily alters the reinforcing properties of a stimulus; and temporarily alters the probability that a person will engage in behavior that in the past, produced that stimulus
establishing operation/setting event
a stimulus change that temporarily increases the value of a stimulus and evokes all behavior that in the past produced that stimulus
abolishing operation
a stimulus change that temporarily decreases the value of a stimulus and decreases the probability of a behavior occurring in the past produced that stimulus.
