Q

How does an enriched environment affect an individual’s abilities?

A

The more enriched the environment, the more likely an individual is to attain the highest (IQ, social awareness, etc.)

Q

Provide examples of neurotoxins.

A
  • Alcohol
  • Nicotine
  • Lead
  • Drugs of abuse
18
Q

How can head injury affect learning?

A

Single or repeated neurological trauma will decrease the ability to learn

19
Q

What are examples of neurological trauma?

A
  • Concussion
  • Stroke
20
Q

What are Critical Periods?

A

A period of time in development in which an animal is especially likely to learn a particular kind of behavior.

21
Q

What is Imprinting according to Lorenz (1952)?

A

A newborn animal is especially likely to discriminate the first stimulus he/she is exposed to as a parent.

Newly hatched chicks would follow whatever they first saw as if it were their mother.

22
Q

What is Preparedness in learning?

A

The extent to which an animal’s phylogenic history prepares or counter-prepares an animal to learn a particular skill.

23
Q

How do animals learn different skills?

A

Animals will learn some skills very quickly and efficiently and other skills slowly, if at all.

Example: Breland’s animal training.

24
Q

What is Instinctual Drift?

A

A tendency for an animal to revert to a fixed action pattern regardless of the learning history/momentum for a skill.

25
How do innate tendencies affect learning?
Innate tendencies to behave in particular ways interfered with learning abilities. ## Footnote Example: Raccoon rub sources of food together to expose edible portions.
26
What is Instinctual Drift?
A tendency for an animal to revert to a fixed action pattern regardless of the learning history or momentum for a skill.
27
What determines the success of operant learning procedures?
The effectiveness will depend on the compatibility of the operant response and the preexisting organization of the organism.
28
What is Biological Preparedness?
Animals are differentially prepared or counter-prepared to have their behavior controlled by conditional-unconditional stimuli.
29
How does conditioning relate to the relevance of stimuli?
Conditioning will be enhanced if the conditioned stimulus (CS) is 'relevant' to the unconditioned stimulus (US).
30
What did Garcia and Koeling demonstrate?
Rats are more prepared to pair external stimuli with shocks and internal stimuli with illness and nausea.
31
What is the Noisy Group in Garcia and Koeling's experiment?
Rats paired external conditioned stimuli (e.g., noise) with external unconditioned stimuli (e.g., shock).
32
What is the Taste Group in Garcia and Koeling's experiment?
Rats paired internal conditioned stimuli (e.g., taste of water) with internal unconditioned stimuli (e.g., illness and nausea).
33
What do the results from Garcia and Koeling indicate about genetic predispositions?
Organisms may be genetically predisposed to pair some neutral stimuli with unconditional fear stimuli.
34
How effective is fear conditioning?
Fear conditioning is more effective with 'fear-relevant' stimuli than 'fear-non-relevant' stimuli.
35
What are sign tracking and autoshaping?
They were discovered by observing that animals approach and contact stimuli correlated with food.
36
What is the difference between sign tracking and goal tracking?
Some animals allocate time and behavior to stimuli paired with food presentation, even if distant from the food location.
37
What is defined as forgetting?
The deterioration in performance of learned behavior following a retention interval.
38
What does deterioration of performance indicate?
Some non-optimal change in behavior.
39
What is a retention interval?
The period of learning in which behavior directly contacts consequences.
40
What methods measure forgetting?
Several methods include free recall, cued recall, recognition, and gradient deterioration.
