“I Swear It Happened!” But It Never Did…

April 27th, 2018 2 comments

Image 1- Ok, Gerard… 

Has someone ever told you a tale that made you think, “That just can’t be true!”. Well, you may be right. Here’s the thing, you may fondly remember your eighth birthday party at a local barn with a bunch of cute animals. You and your friends rode the horses, brushed the horses, and you even remember feeding the horses straight from your hand. Oh, and the cake! Your mother ordered a special strawberry shortcake for your birthday party. The sun was shining, it was a beautiful day, and you remember that party like it was yesterday. But the even more important thing is, none of this really happened.

In reality, you have never ridden a horse in your life and you are allergic to strawberries… Even when a childhood friend of yours gently reminds you that that never really happened, you still firmly believe (and can even remember specific details!) that your eighth birthday party happened exactly that way (Pederson, 2018). Your friend softly says to you, “You have created a confabulation”, to which you respond, “I’ve created a WHAT?!”

Image 2– Maybe… 

Confabulation is a memory disturbance that results in people reporting memories of events in their own personal history that actually never happened. Confabulations can take the form of small inaccuracies, such as simply filling in gaps in one’s memory with false details, or they can be large events, such as the horseback riding birthday party described earlier. Regardless of the magnitude of the memory, it is difficult to convince the person that their “memories” are false.

It is sometimes difficult to identify a confabulation because the person reporting the memory could seem very convincing and in touch with reality, but really the story is untrue (Shingaki et al., 2016). People who confabulate confidently describe imagined scenarios and present them as being completely true (Pederson, 2018). Another difficulty in identifying a confabulation is that a person’s autobiographical memory is generally quite difficult to study because if we did not experience the event with the person telling the story, then we can never really know if it actually happened or not. Even if we can’t thoroughly study someone’s episodic history, we can at least know that the person who experiences these confabulations is not purposefully deceiving you with inaccurate information. In fact, they wholeheartedly believe that what they are saying is the truth (Nall, 2017).

It’s on the Ttt….Tip de mi Lengua: Differences in the Tip of the Tongue States for Bilingual and Monolinguals

April 26th, 2018 No comments

Picture this: you run into someone you met last week. You remember you had a great conversation with them and got along well. But, there’s one problem. You can’t, for the life of you, remember their name.  You know it started with an “A” and was a relatively short name, but you can’t quite say the name out loud as you greet them. It’s RIGHT there though, on the tip of your tongue. Luckily, another mutual friend comes up to both of you and says, “Oh, how do you know Abigail?” Ah, yes, Abigail Rhodes. You remember now.

We all know that feeling that accompanies not being able to articulate something we are confident we know or should know. And, there’s a name for that feeling: it’s called the tip of the tongue phenomenon (TOT).  The TOT occurrence is a cognitive bias that is named after the colloquial phrase “it’s on the tip of my tongue” and helps to provide insights into why, even if we know something, we are sometimes unable to verbalize our answer.

I can’t remember her name… is this a sign of dementia?! The tip of the tongue effect and aging

April 24th, 2018 No comments

It’s a parasite. Small. Drills its way into unknowing individuals’ feet and proceeds to circulate their bloodstream. Common in areas with poor sanitation. I know this parasite from my global public health presentation from just last year. It starts with an ‘S’, maybe even a shhh sound? How could I not remember this? “Schistosomiasis”, my professor stated after what seemed like several frustrating minutes of attempting to recall the name for this parasite.

Why couldn’t I remember a word with which I am very familiar? One with which I spent hours researching on various databases, the CDC, even Wikipedia? It’s called the tip of the tongue (TOT) phenomenon, and if you’re anything like me, you likely experience this ever so maddening effect more frequently than you’d like. I’ve long since wondered about this phenomenon as whenever it happens to my Mum, she claims that she’s “losing [her] marbles” or is developing dementia. Does this mean that I’m developing dementia, too? Cognitively speaking, what is going on when you experience a TOT? But seriously, what is a TOT, anyways? Read more…

What Was That? I Can’t Remember What You Said, I Was Next-In-Line

Don’t You Hate When This Happens?

Imagine it’s the first day of classes for the semester. Your professor announces to the class that you are going to do an icebreaker activity to get to know each other. There are probably a few groans and a little bit of fear from the shyer students. You must tell the class your name, your class year, where you’re from, and a fun fact about yourself. The dread sets in as you panic and try to think of something interesting. You don’t want everyone to think you’re lame or a weirdo. You spend the whole time everyone else is talking trying to think of what to say and finally it’s your turn: “Hi my name is Emma, I’m a senior, I’m from Jacksonville, Florida, and, um, I can lick my elbow.” Now you wonder if maybe that was a little too interesting, while the person sitting next to you talks about his summer in Belize. Or was it Nicaragua? You can’t really remember. Actually you can’t quite recall what any of the people before you said. You were so focused on your own presentation that you did not pay attention to what other people said. This is called the next-in-line effect.

Why can’t I remember the name of the actor in my favorite movie?…I know I know it…it’s on the: Tip of the Tongue Phenomenon

mercercognitivepsychology.pbworks.com A accurate depiction of of TOT happening in our daily lives (minus buying tongues)

Remember that time when you were trying to recall the celebrity who plays the main character in your favorite movie? You knew that their name began with the letter L, that they were in another movie about dreams, and that they finally won an Oscar. You may even say, “it’s on the tip of my tongue”. But for some reason you just can’t recall their name (by the way it’s Leonardo Dicaprio). It is something we’ve all experienced, and it is called the tip-of-the-tongue phenomenon (TOT).

Are Pictures Really Worth A Thousand Words? When It Comes to Memory They Are

April 16th, 2017 4 comments

Have you ever looked at the coverage map for a telecommunications company, like Verizon, and wondered why a company would choose to spend the money on a colored picture instead of just presenting the information in the paragraph? I mean, wouldn’t it be easier and cheaper to just write it all out? Probably, but it wouldn’t be as effective.

Below is a paragraph that describes Verizon’s coverage in the U.S., and a corresponding image that displays the data. When the information is laid out in text, I bet that you, the consumer, would have a much harder time articulating and remembering the information. But by presenting the information in a picture (like that shown below), you can easily discern and remember the differences between the coverage of four telecommunication companies. Why would this be true? It has to do with the way that we encode, or initially learn, information. This is a perfect example of the picture superiority effect, the phenomenon in which people are better at remembering images than they are at remembering words (click here for a quick, fun video that explains this phenomenon).

“Among the four major wireless carriers, only Verizon’s 4G network is 100% 4G LTE the gold standard of wireless technology. Available in over 500 cities, Verizon 4G LTE covers almost 97% of the U.S. population. Experience the speed and power in more places.”

Keep Calm and Encode this Face… Then Panic and Freak Out while Retrieving It!

November 23rd, 2015 2 comments

Imagine that you are sitting in a coffee shop, peacefully eating your cannoli and sipping your latte. As you look out the window, you notice someone approach
a parked car, smash the window, and steal something out of the front seat of the car. Your calm afternoon quickly becomes anxiety-ridden: your leg bounces, your voice shakes, your heart pounds, your stomach churns, and your mind races. You catch a glimpse of the criminal’s face as they are running off, and you promptly call 911. But did you know that the anxiety that you experienced when witnessing the crime could impact your ability to remember the criminal’s face later? We tend to recognize faces pretty easily, especially when someone is familiar to us, so you’re probably thinking that you would also be able to recognize the criminal’s face without a problem. After all, you did just watch them commit a crime right in front of your eyes. PAFF_090513_anxietyperception_newsfeature Your anxiety about the situation may have impaired your ability to recognize that person’s face, though, and a recent study conducted by Curtis, Russ, and Ackland (2015) sought to determine why and how this happens. Their research wanted to see how a spike in anxiety impacts someone’s ability to remember a face. More specifically, they wanted to know when the time of onset of anxiety is most impactful (before or after seeing a face) and whether or not anxiety increases stereotypes, or assumptions about the thoughts, actions, and behaviors another group of people, when someone is recognizing a face that is a different ethnicity than their own.

Is a picture worth one thousand MORE words?

November 23rd, 2015 No comments

Ever notice the diagrams in your textbook? Or the visuals in your professor’s slides? Or maybe the pictures in an instruction manual to construct furniture? It seems that professionals have caught onto the idea that pictures are beneficial to learning and understanding content. Whether is comes to providing information in a presentation, deciding how to best visualize data for a report, or giving directions for a task, it obvious that visual content provides some benefit in absorbing information that is not attainable through simple text. I am going to walk your through when visuals are most helpful, when they aren’t, and how to best include visuals in your own work. Read more…

Test Me Now, I’ll Thank You Later

April 29th, 2013 3 comments

I wish I could have taken a picture of every student’s face that walked into Mr. B’s middle school history class on Friday morning. It was always a struggle to get up on Fridays because I knew that my first class of the day always meant it was time for a quiz. All of my peers despised Mr. B for his quizzes to make sure that we had been paying attention all week and that we were keeping up with the information. “Isn’t that what tests are for? Why do we have to take a quiz every week?”

Teaching To The TestBeing tested frequently is something that students are most of the time not too fond of, but in the long run when you get the grade of your exam, you will thank the teachers that made you recall and tested you on the information learned every week! Recent research in cognitive psychology has provided strong evidence to support this notion.

Retrieval, the process by which information can be extracted from memory, is treated as an evaluative tool that reveals what people remember and what they have forgotten; retrieval shows what people know but it also changes what people know. From an educational perspective, it is important to understand that retrieval serves more than just the purpose of reinforcing memory of a tested fact! Cognitive psychologists have recently been seeking to provide educators with clear, effective advice on how to improve student learning.
