“Ohhh, ‘Cue!'”: Cue-Dependent Forgetting and Study Techniques

November 26th, 2019 2 comments

Picture yourself in a classroom taking a history quiz. You don’t consider yourself a history buff of course, but you feel as if you studied well enough. You breeze through the questions, until you come across one that stumps you a bit: “Which U.S. President served the shortest term?”. You have to know this, of course, because you remember looking over it yesterday. The weight of familiarity is killing you, as you rack your brain and sort through the order of United States Presidents you thought you had memorized. When you studied, you paired the President’s last names along with common words that sounded similar–Lincoln and Linkedin, Kennedy and candy– you thought you pretty much had it down. Your heart thumps as you begin to look around the room, hoping something will strike your memory and soon your attention is drawn to how weird your teacher’s hair looks today. Hair, hair, Harrison! Suddenly you have it, William Henry Harrison was the President who served the shortest term.

Ok, let’s try that scenario again: you find yourself looking around the room for something to spark that lightbulb in your mind, but nothing seems to do the trick. Your professor is bald and always has been. You simply just can’t remember the name you were looking for and accept defeat. You stare daggers at their head as you leave that question blank and go onto the next one.

What made these two scenarios so different? The second scenario describes a cognitive psychology term called “cue-dependent forgetting” where a person is unable to remember information in the absence of a retrieval cue (Chandler & Gargano, 1995). A retrieval cue in this case is something that signals or prompts the memory of something that you associated with it (Chandler and Gargano, 1995). In the previously described scenario, the retrieval cues were the common words that sounded similar to the President’s names. This is why, when the retrieval cue for Harrison (“hair”), was forgotten, you were unable to answer the question. Pairing items as a form of studying may seem like an efficient way to quickly memorize material, but as seen in the example, it isn’t always reliable. Why does cue-dependent forgetting happen? And are there ways to prevent it from having a negative effect on test performance? These questions can be understood with a quick summary of how memory works.

Who Needs a Crystal Ball to See the Future When Hindsight Bias Makes You Feel as if You Knew it All Along

November 25th, 2019 1 comment

“I just can’t stand it anymore!” For the last two weeks, this has been Katie’s way of announcing to her mother that she is home from school. Why is Katie so upset? I’ll give you a hint- it’s March of her senior year and she is waiting on something…

You’re probably thinking, oh college decisions! That must be what she is waiting for.

Good guess, but this is something much more nerve-wracking.

She’s waiting for her crush to ask her to the senior prom.

“What happened today, sweetheart?,” her mom asked. “Ok, so it was during lunch and I was standing in front of Drew in the sandwich line. I totally saw him checking me out, so I thought, ‘might as well flash a smile his way’, so I smiled AND said hi to him. And you know what he did back? NOTHING. He pretended like I didn’t exist! Can you believe him?!”

“Well, maybe he didn’t see you Katie. I wouldn’t worry about it; I’ve seen the way he looks at you. Drew clearly likes you.” Katie groaned. “Sorry mom, but I think you’re wrong on this one. I’m just going to accept the fact that he NEVER is going to ask me out.”

“Just wait it out Katie; you always try to control the situation, but sometimes matters like this need time to work themselves out.” Katie rolled her eyes. “No, I think I’m just destined to live alone my whole life with only cats to keep me company. The sooner I accept reality the better.”

*One Week Later, Katie’s on the phone while walking into the house*

“Brittany, I know, what can I say, it was only a matter of time before he was going to ask me. Have you noticed the way he looks at me? I’ve known he was going to ask me the whole time.”

Katie may feel as if she knew it all along but she’s not fooling us…

“Katie, is that you? Did I just hear you say Drew finally asked you to the prom? This is so exciting! I told you not to worry.”

“Brittany, give me a second my mom is talking to me. What do you mean, worry? I’ve known he was going to ask me all along.”

*Katie leaves the room*

“Knew it all along huh?” Katie’s mom picked up an advertisement addressed to Katie from the counter. “I guess she won’t be needing this cat poster of the month subscription anymore”.

Like Katie’s mom, you may be confused as to why Katie suddenly feels as if she knew Drew was going to ask her all along when it’s evident she didn’t.

One possible explanation is hindsight bias.

Get Ready…You’re Next.

November 24th, 2019 2 comments

“When will I get to speak” – Instead of attending to Mr. Know-It-All, they wait in anticipation for their turn to speak next.

Imagine that you are in class and your teacher has split the class into multiple groups, assigning each group different chapters of your reading to summarize for the class. In your group, you collectively brainstorm with your other group members about chapter four and write down the main topics and themes that pop up throughout your discussion. When your teacher signals that it’s time for each group to share what they talked about, all your group members assign you to be the spokesperson since you have jotted down some general notes. “Yeah, sure. It’s no big deal,” you think to yourself. “It’s not a formal presentation or anything, I just have to summarize what we talked about.” The group’s spokesperson for chapter one goes first, followed by the group’s spokesperson for chapter two and then chapter three. As it nears your turn, you start to think about how to present a clear and concise summary to the class as your classmates have just done. All of a sudden, you’re up next, so you stand up and tell the class about the main topics your group discussed. When you sit back down, the group for chapter five begins to share, but you look back over your notes making sure you did not forget to include anything important. At the end of class, your teacher gives a mini quiz about the chapters the class just summarized, and you realize that you can’t really remember anything from the presentations on chapter three or five. What happened? You were subject to the next-in-line effect.

“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

Unknown

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.
