Describe the development of attention from infancy to adolescence.

As children get older... 1) their attention spans become longer 2) become more selective in what they attend to 3) better able to plan and carry out systematic strategies for using their senses to achieve goals Infancy: - selective attention: deliberately concentrating on one thing while ignoring something else - with age, attention becomes more selective and less susceptible t0 distraction - @ 2 yrs, able to form plans of actions --> guides what they focus on and what they ignore - systematic attention Adolescence: - longer attention spans - improved considerably between childhood and adulthood (b/c of increase myelination of the portions of the brain that help regulate attention) - become more efficient at ignoring irrelevant information - can divide their attention more systematically between two taskswwe

Who is Thorndike and what did he believe?

Law of Effect - the response to a stimulus is affected by the consequence of that behavior - trial & error learning results in some behaviors (those follows by a good consequence) being "stamped in", while others (those follows by discomfort or unpleasant consequences) are stamped out - behavioral response is affected by the consequence of that behavior - behavior changes because of its consequences - rewarded behavior is likely to reoccur

What is latent learning?

Learning occurs but is not evident in behavior; children can learn from observation even though they do no imitate (perform) the learned responses - learning that occurs but is not exhibited until there is reinforcement or an incentive to do so

What did Watson do?

Little Albert Experiment (classical conditioning - fears are not innate and can be learned) Rat was presented to Albert and showed no fear --> after presenting rat to Albert, Watson bangs a steel rod with a hammer (UCS) for fear (UCR) --> during conditioning, stimuli of the rat and the loud noise were presented together several times --> Watson present the rat without the bang --> Albert begins to whimper and cry (white rat - CS; fear after rat- CR) --> same response is generalized with furry items *emotional responses can be learned*

What is classical/associative conditioning?

Watson - behaviorism: Believed that conclusions about human development and functioning should be based on observations of overt behavior rather than on speculations about unobservable cognitive and emotional processes - Classical conditioning: a simple form of learning in which a stimulus that initially had no effect on the individual comes to elicit a response through its association with a stimulus that already elicits the response - we learn associations b/w events, anticipate important events - stimulus happens first and ELICITS the response; behavior then follows - Like John Locke

What is generalization?

When stimuli that are similar to the CS evokes some level of the CR

What is preferential looking/visual preference method?

Does early experience affect later taste preference?

Yes - babies that had a greater exposure to a variety of flavors during infancy may lead to a more adventurous eater later on - early experiences with different flavors also extend to the prenatal period and exposure to different chemicals in the amniotic fluid *cannot discount genetic predisposition!*

Can babies hear before birth?

Yes; fetuses can hear some things outside of the womb 3 months before birth
