The physiological explanation for the cocktail phenomenon is given by a narrator and corresponding figure. A diagram includes red particles, which represent sound information. All the particles (sound) enter the ear, but some sounds do not make it past the filter. Have you recently been in a situation that required selective attention? How does selective attention operate according to the filter theory?
An anchor interviews Angela Chan on one way to improve memory, improve the depth of processing. Chan gives an example of elaboration and the bizarreness effect. She parked in E6, and to remember it she created an image of an elephant with six appendages. Chan explains the cognitive background that accounts for the effects.

A man plays blackjack with a woman. He eventually gets her phone number and the order to call her. The man attempts to repeat her phone number, but other numbers in the background distract him. A voiceover discusses the limits to short term memory, and a rule: repeat to remember. Author John Medina states that if you repeat something within thirty seconds that your brain will hold on to that information for 1-2 hours. Do you support his view? Why or why not? What empirical evidence would convince you of the repeat to remember rule?
This video presents a study testing peoples visual memory. Researchers were surprised by just how much detail people were able to retain after viewing thousands of images for only three seconds each. What type of memory is being used by the volunteers? Would the instructions volunteers are given at the start make a difference as to what type of memory is being used?
This short clip demonstrates a game called Iconic Memory in which several white circles are revealed and then hidden, and the player must remember where those circles were placed on the screen. Why is this game called Iconic Memory? Do you think the name is appropriate? Why or why not?
Stephen Wiltshire, a man with autism, has an extraordinary savant ability. He can fly over a major city and then redraw the city perfectly from memory. Why might the fact that Stephen has autism contribute to his abilities?
A reporter asks people on campus a question that arouses the tip of the tongue state. Researcher Karen Humphries describes some of her laboratory work on tip of the tongue states. Her data suggest that people look for the answer rather than struggling in the tip of the tongue state. What does the tip of the tongue phenomenon tell us about storage and retrieval?
This news clip discusses the validity (or lack there of) of repressed memories. Several stories are told of people who remembered horrific events that turned out not to be true. What are some of the arguments made as to why these memories are unreliable? Why would recovering these memories during hypnosis affect their reliability?
Psychology students Paul, Alex, and Mike created a music video of their rap song which contains psychological topics and concepts. Their review of the years content included research methods, electroshock therapy, brain structures, sleep, cognition, learning, clinical, and social psychology. The song does not contain much detail on the topics, but breadth. How does a rhyme or rap help students remember information?
The man featured in this video has one of the worst cases of amnesia ever documented. The only memories he retains are who his wife is, and how to play the piano. The cause of the problem is not revealed what are the four common causes of amnesia, and what would you speculate is the cause for this man?
Recent studies show that certain mental activities may delay or prevent memory loss later in life. A new program being offered at some senior centers is taking that news to heart. This training is a combination of learning new techniques to deal with memory loss, as well as attempting to reverse some of that loss. Which part of the training do you think is more effective?
This is not a plot device in the latest thriller, it’s real – scientists have shown that injecting an experimental drug into the brain can completely erase long-term memory in animals. Obviously there are some serious ethical issues to deal with before such a drug could be used on humans, but what are some of the potential benefits?
This scene from Finding Nemo demonstrates Dorys short-term memory loss. How does short-term memory function differently from sensory memory or long-term memory? Do you think Dorys condition is a family trait, as she claims, or might there be another explanation for it?
This news clip explains a technique called Brain Gym, that is designed to help students succeed in school.

If not, why not?
The so-called “cuddle hormone”, oxytocin, is known to increase generosity and trust. Now a new study shows it can improve on a persons ability to remember facial features. Why might this hormone have evolved in this way? What would be the advantage of remembering faces over other objects?

Closeness counts when it comes to how strong our memories are. While many people remember where they were when they heard the news of attacks on the World Trade Center, brain researchers say those who were close to the scene formed memories that still provoke the brain’s response to danger. What sort of stimuli might account for the different reactions of those who were close to the event?
Dr. Sanjay Gupta and Soledad O Brien of CNN discuss Sian Beilocks research on intelligence and choking. When pressure, time demands, peers, and monetary rewards were added to a task, participants with a high working memory capacity did 10% worse than when they completed the task under no pressure. Participants with a lower working memory capacity received the same score regardless of pressure. Explain the working memory capacity trade-off under high pressure. Who performs better, people with high working memory or low working memory?
