How Neurons Communicate: The Synapse (Intro Psych Tutorial #25)
In this video I explain how two neurons communicate using a neurotransmitter that travels across the synapse to receptor sites. This neurotransmitter can then influence the flow of ions in the postsynaptic neuron which can change its likelihood of firing an action potential.

In this video I introduce the work of developmental psychologist Jean Piaget. Piaget proposed a stage-based theory for how we develop our cognitive abilities. Piaget viewed children like little scientists who were constantly testing and updating their knowledge structures, or schema, for how the world works. When encountering something new, children either assimilate this new knowledge into their existing schema, or they need to accommodate, modifying their schema in light of the new information.

In this video I describe the importance of active retrieval for long-term retention of material and how we should include what Elizabeth and Robert Bjork call "desirable difficulties" in our learning and studying. I try to follow the general principle of using my mind as the primary tool in my studying and treating all other materials and resources as secondary to what I can do on my own. This view can help to simply studying and learning, even though it often makes it more difficult or frustrating.

In this video I go into more detail on pain perception. First I discuss the importance of pain as a signal of danger or harm to the body. Next I explain the two types of nerve fibers which carry different pain messages: A-delta fibers for sharp, intense pains and C-fibers for dull, throbbing pains. I provide a mnemonic for remembering the fiber types and then discuss two other concepts related to pain: gate control theory and referred pain.

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 tools as having single fixed uses and this may cause us to overlook novel uses for them. Convergent thinking refers to approaches leading to a single solution, while divergent thinking refers to coming up with many possible solutions which may not be related to one another.

In this video I consider interventions aimed at improving cognitive performance including brain stimulation, off-label drug use, nootropics, and brain training games and apps. While unfortunately there isn't much evidence that any of these can improve fluid intelligence (as measured by assessments like the Raven Progressive Matrices) that can transfer to other tasks, this doesn't mean that we can't make improvements in specific tasks. We can still improve our crystallized intelligence and proper sleep, diet, and exercise can help us to make the most of our potential.

In this video I describe how understanding the capacity limitations of working memory can help us to study more effectively. We need to know how cognitive loads can reduce performance and more importantly, how this can be overcome to develop expertise. By using "chunking" and focusing on which aspects of learning can and should be automated, we can free ourselves to learn more quickly.

In this video I explain the distinction between intrinsic and extrinsic motivation and then discuss the overjustification effect demonstrated in a study by Mark Lepper, David Greene, and Richard Nisbett in 1973. Then I consider how the overjustification effect may relate to work in fields like art, music, or athletics and how it may also influence the intrinsic motivation of students who receive external rewards for their academic achievements.
