In this video I describe a spectrum of consciousness, ranging from minimal consciousness up to full human consciousness. Along the way, recognition of the self may be an important marker for differentiating some animals. The ability to be self-conscious and … Read More
Problems of Consciousness
In this video I begin the unit on consciousness by considering a number of problems associated with understanding consciousness. These include the mind-body problem, the problem of other minds, and the hard problem of consciousness. While we don’t have solutions … Read More
Benefits of Heuristics
In this video I end the unit on cognition with the reminder that heuristics are not just about making errors in decision-making. Most of the time heuristics work well and they serve as useful tools for making sense of the … Read More
The Sunk-Cost Fallacy
In this video I introduce the sunk-cost fallacy, which is when we make present decisions based on previous investments which aren’t relevant. This fallacy can occur in the form of gamblers or investors who make increasingly risky decisions in order … Read More
The Framing Effect
In this video I introduce Tversky and Kahneman’s work on the framing effect and how consideration of benefits or losses can influence the choices that people make and their willingness to take risks. I consider a few everyday examples of … Read More
The Representativeness Heuristic
In this video I describe another heuristic identified by the work of Amos Tversky and Daniel Kahneman. The representativeness heuristic is a shortcut that we use when attempting to estimate the odds of something being true, such as whether an … Read More
The Availability Heuristic
In this video I provide an introduction to behavioral economics and the work of Amos Tversky and Daniel Kahneman by describing a heuristic we use when attempting to assess the frequency of events. The availability heuristic is a shortcut that … Read More
Problem Solving: Algorithms vs. Heuristics
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
