Digesting food is behavior determined by factors while chewing food (masticating) is determined by factors.

1. Ontogenic, Phylogenic

2. Phylogenic, Ontogenic

3. Operant, Respondent

4. Cultural, Ontogenic

Fixed Action Pattern •A relatively rigid sequence of responses that once initiated, will continue despite any effects on the environment

•Occurs in male and female species of animal kingdom

•Phylogenic origin of behavior

Ex1. Spider weaving web

Ex2. Mating dances of many bird species

Ex3. Nest making of many species

5

Modal Action Pattern (MAP) •Term recognizes unique variations of rigid sequences of behavior due to environmental (ontogenic) influences on behavior that is shared by all members of species

•EX: yawning • Variation in duration, frequency and topography

• In wake hours, yawning often accompanied by stretching

Reaction Chains •Organism’s behavior produces stimulus change that triggers next response in the chain

Ex1: mating dance of stickleback -Presence of female will trigger the zigzag dance

-If female arches her back revealing a swollen abdomen of eggs, male fish will swim towards a constructed nest

-Female follows triggers male fish to nibble base of tail of female fish and initiate egg laying

-Depositing of eggs in nest triggers male to enter nest and fertilize eggs completing chain

Sexual Selection •Ensures that genes related to successful reproduction are more likely to be present in offspring and future generations through female choice and male competition

•Ex1: Size of male crabs claw

•Ex2: Size of male hummingbird tale

Reflex - Review The term reflex refers to a relationship between:

◦ A stimulus + an innate, involuntary response

In a reflex, the stimulus elicits the reflex response

We use the term elicit to indicate that the stimulus will produce the response EVERY TIME ◦ Elicit is ONLY used to describe respondent behavior

◦ Evoke is ONLY used to describe operant behavior

10

Unconditioned Reflex Response

•Critical attributes of unconditioned reflex responses are;

1. Species specific: shared by all members of a species

2. Innate, phylogenic origin: most likely serve an adaptive function for survival

3. Stereotypic: each occurrence of the response is pretty much the same in strength, form, and time in development

4. Involuntary:

• Mediated by the Autonomic Nervous System (ANS)

• Bypasses central cortex

5. Invariant in time of appearance during development

11

Reflex Responses Variant attributes of an unconditioned reflex response are; 1. Time of appearance

• Most appear in infancy, some reflexes appear later in life

2. Retention of the reflex response

• Most are present throughout entire lifetime, others disappear after infancy (e.g., Moro reflex)

3. Tissue type:

• Executed mostly by the smooth muscles & glands

• Some exceptions that involve striated (skeletal muscle such as patellar reflex) and cardiac muscles (i.e., heart beating)

ASR Which of the following is NOT one of the primary laws of the reflex?

1. Law of the threshold

2. Law of attenuation

3. Law of intensity-magnitude

4. Law of latency

Law of the Threshold •Weak intensities of a stimulus will not elicit a response

•As intensity of eliciting stimulus increases, there is a point in which responses will be elicited

•Uncertainty region represents intensity region where 50% of stimuli presented produce a response = threshold

Law of Intensity-magnitude •Relationship between intensity of stimulus and size or magnitude of elicited response

•As intensity of US increases, magnitude of UR increases to a certain point

ASR As intensity of US increases, time for the UR to appear decreases. This statement describes this law.

1. Law of the threshold

2. Law of intensity

3. Law of latency

Habituation

Reduction in the strength of reflex response due to repeated exposure to the stimulus that elicits the response

20

Adaptation

Reduction in the frequency or magnitude of a response or a set of responses as a result of prolonged exposure to a stimulus or an environmental context.

Sensitization Tendency of another stimulus to elicit a reflex response following the elicitation of that same response by a different stimulus

23

Potentiation

Temporary increase in some dimension or intensity of a reflex response due to repeated presentations of an eliciting stimulus.

Most likely to be produced by an aversive antecedent stimulus.

Opposite of habituation.

CONTIGUITY IS EVERYTHING! 1) Short delay : most overlap, CS presented shortly before = very effective

2) Long delay : some overlap, CS is presented long before US = usually effective

3) Trace conditioning : no overlap, CS is removed when US is presented = sometimes effective

4) Simultaneous conditioning: CS and US presented at the same time = rarely effective

5) Backward conditioning: opposite of short or long delay = almost never effective

41

Contingency

• Dependency between events, one event depends on another

•Dependency between US and CS matters for respondent learning

•US should occur more often when the CS is presented

4. Trace, Short Delay

46

Respondent Extinction

•Respondent extinction is achieved through unpaired presentations of the CS (without the US)

•EX: When the US (food) does not follow the CS (tone), CR (salivation) begins to decrease and eventually causes extinction. – Eventually the reflex response will cease to be elicited by the CS.

17

Spontaneous Recovery •Spontaneous recovery refers to the re-emergence of the CS-CR relationship after extinction has occurred.

•EX: After a rest period, an extinguished CR (salivation) spontaneously recovers, when the CS (Bell) is presented.

•But since the CS persists alone, the CR becomes extinct again.

49

Spontaneous Recovery

50

Respondent Stimulus Generalization

•Spread of the effects of respondent conditioning to stimuli other than the conditioned stimulus.

•Most likely to occur the greater the similarity between the CS and the other stimulus.

ASR •When an organism responds to one value of a CS with a particular response but not to other values of the CS, it is called

1. Habituation

2. Respondent extinction

3. Spontaneous recovery

4. Stimulus generalization

5. Respondent discrimination

ASR The general yells “fire” and then the soldier hears gun shots. His heart jumps. Soon whenever the general yells “fire” the soldier’s heart races even before hearing the gun shots. Finally, the army surrenders and puts down their guns. The general still yells “fire” over and over. The soldier's heart stops racing to the sound of the general yelling “fire.” This demonstrates:

1. Habituation

2. Respondent extinction

3. Spontaneous recovery

4. Stimulus generalization

5. Respondent discrimination

53

ASR Some time after the war, while shooting at the gun range, the same soldier hears a man yell, “Fire.” His heart immediately starts to race. This demonstrates:

1. Sensitization

2. Operant conditioning

Conditioning as it relates to food choices •Every eaten a food and then become ill?

•Every drank something and then become ill?

•Learned response is avoiding food/drink that made us sick

•Food /drink that made us ill becomes a CS (smell, sight)

•CR would feelings of illness such as nausea

•Known as conditioned taste aversion

•Forms basis of treatment for addictions using aversion therapy

•https://www.youtube.com/watch?v=a991fpwJd_4

Higher order conditioning

•When a US is paired with a CS and CS begins to elicit the CR, establishes first order conditioning • Meat powder paired with bell

• Bell elicits salivation

•Also serves as foundation for higher order conditioning where a CS can condition a second a neutral stimulus • Bell paired with a tone

• Tone eventually elicits salivation

• Called second order conditioning

65

Conditioning and drug abuse •Drug tolerance: a decrease in response of drug usually resulting from repeated use

•Stimuli associated with taken drug become conditioned stimuli occasioning cravings for drug • Examples include places of drug consumption, drug paraphernalia and persons associated with

consumption of drug

• Preparatory conditioned stimuli increase tolerance for drug through conditioning of compensatory conditioned responses

• Ex: If drug increases heart rate, compensatory CR would be to decrease heart rate

•Drug users develop tolerances resulting in consumption of increasingly higher doses of drug • Increases risk of overdose particularly when drug ingested in novel area

3. Conditioned withdrawal

Conditioned Immunosuppression •Placebo effects may be explained through respondent conditioning

•Placebo drug may elicit CR related to feeling better such as; • Lower blood pressure • Lowered heart rate • Release of neurotransmitters in brain • Release of endorphins and hormones

https://www.youtube.com/watch?v=z03FQGlGgo0

•Vaccines and immune response also thought to involve respondent conditioning • Immune system’s reaction to vaccine trains immune system to react to other pathogens through

respondent generalization • Often referred to as “Adaptive immunity” • https://www.youtube.com/watch?v=rb7TVW77ZCs
