The World's Best Book Summaries
Do you ever remember an event differently than someone else who was there? How do fake memories form in the brain? A fake memory is one that is remembered differently from how it happened or one in which details of a thing or event are wrong. But, don’t worry—everybody has fake memories. It’s part of how the human brain functions. Here’s why your memory may be playing tricks on you.
Are you perceiving reality accurately, or do you have blind spots in your perception? Does everybody perceive the world in the same way? According to Harvard professor and social psychologist Daniel Gilbert, we all are perceiving reality through a distorted lens. Gilbert says that your brain fabricates your present reality by filling in visual and aural gaps in your perception with assumed information—and by interpreting present events in a way that’s advantageous to you. Here are the two fabrications that most people make about reality.
What’s the most effective way to size up someone’s personality? How much information do we really need to accurately size up a person’s qualities? When it comes to reading personalities, we really don’t need much information. In fact, too much information can obscure the bigger picture with irrelevant details. Taking a “thin slice”—an extremely small segment of information about a person’s life—can lead to very accurate judgments about their personality. Here’s why “thin-slicing” is the best way to judge a personality.
What’s an “insight problem”? How do you solve such a problem? An insight problem is a problem that requires a fundamental shift in perspective in order to arrive at the solution. Oftentimes, the solution to an insight problem comes out seemingly out of nowhere in an “Aha! moment” fashion. In 1931, psychologist Norman Maier investigated how we arrive at solutions to insight problems in his famous Two-String Problem experiment. Here’s what he found.
Why do we like what we like? How do we determine our own preferences? Are our judgments about our own likes and dislikes always accurate? We’re good at making fast judgments about what we do and don’t like. But, surprisingly, sometimes these snap judgments about our own preferences can be inaccurate. Here’s why your judgments about what you do and don’t like may not reflect your actual preferences.
What is the mere exposure effect? Why do we like things that are familiar and dislike what’s unfamiliar? The mere exposure effect occurs when we start to like things just because we’ve been exposed to them before. It applies to everything from the people we interact with to that song that keeps playing on the radio. Here’s why we like the familiar and try to stay from the unfamiliar.
What is the function of the ventromedial prefrontal cortex (vmPFC)? What happens when the vmPFC brain region is damaged? The ventromedial prefrontal cortex (vmPFC) is an area of the brain which has been extensively studied with regard to value computation. Observing patients with ventromedial prefrontal cortex damage has yielded some intriguing insights into the way the brain makes decisions. Learn about vmPFC’s role in decision-making, and what happens when it’s damaged.
What is priming? What are the different kinds of priming? In psychology, the priming effect occurs when exposure to a previous stimulus influences one’s reaction to the subsequent stimulus. Priming has been extensively researched in studies of a wide range of social and psychological phenomena, including memory, motivation, stereotyping, and prejudice. Learn about the psychology of priming.
What is the “left brain interpreter”? How does the brain assimilate new information? The left brain interpreter is a neurophysiological concept that refers to the brain’s process of making sense of new information by relating it to existing knowledge. Although the concept was based on the studies of split-brain patients—patients who had their corpus callosum severed—it applies to neurotypical populations at large. Keep reading to learn about the left brain interpreter and its role in sense-making.
What is the Implicit Association Test (IAT)? How does the IAT measure bias? In psychology, the Implicit Association Test (IAT) is an assessment designed to gauge mental representations that are outside conscious control. It is supposed to measure unconscious bias by measuring how fast a person can assign descriptors to certain categories (e.g. race or gender). Learn about the Implicit Association Test, how it works, and what it’s supposed to measure.
