23. Creativity and Problem Solving

24. Increasing critical thinking & creativity
• Redefine problems. We can modify boundaries and assumptions by rephrasing a problem at either a
more abstract or a more concrete level.
• Use subgoals. By developing subgoals, we can divide a problem into intermediate steps. This process,
known as fractionation, allows us to examine each part for new possibilities and approaches, leading
to a novel solution for the problem as a whole.
• Adopt a critical perspective . Rather than passively accepting assumptions or arguments, we can
evaluate material critically, consider its implications, and think about possible exceptions and
contradictions.
• Consider the opposite. By considering the opposite of a concept we’re seeking to understand, we can
sometimes make progress. For example, to define “good mental health,” it may be useful to consider
what “bad mental health” means.
• Use analogies . Analogies provide alternative frameworks for the interpretation of facts and help us
uncover new understanding.
• Think divergently . Instead of the most logical or common use for an object, consider how you might
use the object if you were forbidden to use it in the usual way.
• Use heuristics . Heuristics are cognitive shortcuts that can help bring about a solution to a problem. If
the problem has a single correct answer and you can use or construct a heuristic, you can often find
the solution more rapidly and effectively.
• Experiment with various solutions . Don’t be afraid to use different routes to find solutions for
problems (verbal, mathematical, graphic, even dramatic). For instance, try to come up with every
conceivable idea you can, no matter how wild or bizarre it may seem at first. After you’ve come up
with a list of solutions, review each one and try to think of ways to make what at first appeared
impractical seem more feasible.

25. Language

26. Grammar: Language’s language
phonology, syntax, semantics
Phonemes: fat, fate
“John kidnapped the boy”
“John, the kidnapped boy”
“The boy kidnapped John

27. Developing language: babble

28. Developing language: production of language
Telegraphic speech Overgeneralization

29. Developing language: language acquisition
Learning Theory Approaches: Language as a Learned Skill
language acquisition follows the principles of reinforcement and conditioning
Nativist Approaches: Language as an Innate Skill
humans are born with an innate linguistic capability that emerges primarily
as a function of maturation. All the world’s languages share a common
underlying structure called a universal grammar
Interactionist Approaches: combination of the above
we have the hardware that allows us to develop language, and exposure to
language in our environment allows us to develop the software to
understand and produce language

30. The influence of language on thinking
linguistic-relativity hypothesis: language is the cause of certain ways of thinking;
language shapes and may determine the way people in a specific culture perceive
and understand the world.
Vs.
thought produces language
