-it seems as though as our brain develops, there are time periods where it focuses on learning
specific things; for language, 2-5 years old is the critical time to learn
-for a infant, it focuses on learning language and how they use their body (6 months-1year old)
-young children who immigrate will learn the language faster than their parents
-once someone is beyond the critical period to learn language, it becomes hard to adapt to new
-there is a theory that since humans have language capacity, chimpanzees may have language
capacity since they share much of our DNA
-there have been studies in which researchers tried to raise the chimp like a human and see if
they can communicate like humans, which is what project Nim is
-however, the chimps do not have the vocal apparatus like humans do, and will not be able to
speak exactly like humans, instead they learn a form of sign language
-Nim got very far in learning words, but he had a hard time chaining words and connecting
meanings behind words
-another example is Koko, who is a gorilla that learned signs to communicate; she also can only
speak in single words and not able to show complex language skills
-ant can communicate to other ants by leaving a scent trail to food
Lecture 25 & 26: Thought
-how do humans think?
-we like to think we are intelligent people that do things with a rational mind, however it may
not always be the case
-we, in a way, act rational, through conditioning, we will repeat what rewards us
-an idea is the rational choice theory in which we will act in a rational way to maximize their
own benefits
-ho ofte do e ake atioal hoies? The esult is that e do’t ake atioal hoies as
often as we like to think
-we tend to either think fast (impulsive, but quick decisions) or slow (rational and slow decision)
-the gale’s fallay is he you thik a esult is due to appea sie the past esults hae ot
been that result, even though the probability is equal
-hot hand theory is when for instance a player hits 300 (3/10 times), and the announcer will say
he is due, like he will be able to hit for sure, but actually the probability is 30%
-heuristics are a form of quick decision making and alternative way to rational thought
-we tend to believe something is more common by how quickly it comes to mind, for instance
fuitue is oe likely to kill you tha you dog, this is due to the edia’s epots (aailaility
-we are more likely to associate someone by their personality despite the probability being
against the description of their personality, this is the basis for stereotypes and prejudice
(representativeness heuristic)
-Malol Gladell’s Blik is a ook aout the poe of fast thiking and the perils of it
