In this video I explain the difference between an algorithm and a heuristic and provide an example demonstrating why we tend to use heuristics when solving problems. While algorithms provide step-by-step procedures that can guarantee solutions, heuristics are faster and … Read More
Obstacles to Problem Solving
In this video I introduce several potential obstacles to problem-solving including overconfidence, illusory superiority, belief bias, and belief perseverance. Then I describe a “consider the opposite” strategy for potentially reducing the influence of bias when interpreting evidence that supports or … Read More
Problem Solving
In this video I introduce several concepts related to problem-solving. I begin with mental set, which refers to our tendency to rely on approaches that have worked in the past. Similarly, functional fixedness refers to our tendency to think of … Read More
Category Recognition

How Does Language Influence Thought?
In this video I consider the relationship between language and thought. The Whorf-Sapir hypothesis, or linguistic relativity hypothesis, suggests that one’s language influences one’s perception of the world. While evidence is mixed on just how language influences thought, there are … Read More
The Interactionist Approach to Language Acquisition
In this video I describe the interactionist approach to language acquisition. This approach recognizes our genetic predisposition for language and considers how the social environment plays a role in that development. Children are learning more than just vocabulary and syntactical … Read More
Language Development
In this video I provide an overview of language development in children. Children learn thousands of words within a matter of a few years and they seem to effortlessly pick up and apply the rules of grammar, first in their … Read More
Universal Grammar
In this video I provide a brief introduction to Noam Chomsky’s theory of Universal Grammar, which suggests that all human languages must share certain features. The human predisposition for language acquisition which allows us to acquire any human language depending … Read More
Introduction to Linguistics
In this video I introduce some terminology from linguistics for describing how languages use sounds to represent meaning. Phonemes refers to the individual sounds used in a language, while morphemes refer to units of meaning. Phonological rules dictate how sounds … Read More
Language Acquisition: Skinner vs. Chomsky
In this video I introduce language acquisition as a type of learning that isn’t explained well by the behaviorist principles we saw in the unit on learning theory. In the next few videos we’ll be looking at linguistics and language … Read More
