What is a recessive gene?
A gene that has to come from both parents in order to be expressed in a phenotype (physical trait)
What is a dominant gene
A gene that is fully expressed in the phenotype and doesn't need both parent to have the phenotype to express it
Define: Threadlike, structures made of DNA molecules that contain the genetic code
Define: A molecule containing the genetic info that makes up the chromosome
Define: Agents, such as chemicals, and viruses, that can reach the embryo or fetus during pregnancy and cause harm
Define: an unlearned, automatic response to a sensory stimulus
Think of examples a baby give as a reflex
Define: psycholocial development contributed to our understanding of personality development throughout the lifespan.
Define: An associating is formed between two events it doesn't control. Bell=food
Define: Food in mouth causes automatic drooling. The food is the stimulus that triggers salivation
Unconditioned classical stimulus UCS
Define Drooling without stimulus
Unconditioned Classical Response UCR
Define A bell is now a stimulus that is associated with food
Conditioned stimulus CS
Define The learned response to a previous stimululs. Ie. A bell makes a dog drool
Conditioned response CR
What experiments did Pavlov do?
What experiments did Watson do?
Little Albert..."Fear can be learned"
Define: In classical conditioning, the tendency, after conditioning, to respond similarly to stimuli that resembles the conditioned stimuli
Define: in classical conditioning, the learned ability to distinguish between a conditioned stimulus and other irrelevant stimuli
Define: in classical conditioning, the weakening of a conditioned response when an unconditioned stimulus begins triggering the conditioned response (in operant conditioning, the weakening of a response when it is no longer reinforced.
Define: The reappearance, after a pause, of an extinguish conditioned response
Define: people/ animals associate their own actions based on consequences, good or bad.
(reward or punishment)
Who performed operant conditioning?
Skinner "skinner box"
Define: is a schedule of reinforcement where a response is reinforced only after a specified number of responses. This schedule produces a high, steady rate of responding with only a brief pause after the delivery of the
Fixed ratio FR
Define: schedule is a schedule of reinforcement where a response is reinforced after an unpredictable number of responses.
Variable ratio VR
Define: schedule of reinforcement where the first response is rewarded only after a specified amount of time has elapsed.
Fixed interval FI
Define: a schedule of reinforcement where a response is rewarded after an unpredictable amount of time has passed.
Variable Interval VI
Define: neurons that fire when we preform certain actions or observe others doing so
