Don't Practice Before You Speak: Your Memory Deficit May Make You Miss Your Boss' Signal to Stop

How many times have you rehearsed telling your partner bad news?  Honey, I rammed the car through the beauty shop window.  But no one was hurt!

Now a new study says that anticipating performance before a school or work presentation can cause you not to remember what happened before the event.

So who cares?  According to newswise.com, "Performance anticipation could weaken memory because people tend to focus on the details of their upcoming presentation instead of paying attention to information that occurs before their performance," says lead author Noah Forrin, a postdoctoral fellow in Psychology at Waterloo.  "People who experience performance anxiety may be particularly likely to experience this phenomenon."

Building on what previous research called the next-in-line effect, Forrin and his co-authors explored how different ways of preparing for a presentation can have an impact on the "pre-performance memory deficit," the web site reports.

That could mean not catching the signal that your boss is giving you to stop.

"They experimented with a variety of techniques that enhance memory, including the production effect, which is the simple yet powerful idea that we can remember something best if we say it aloud," newswise says.

The web site explains that one of the study's co-authors, psychology professor Colin MacLeod, coined the term "production effect" from previous research which identified that reading aloud involves at least three distinct processes that help to encode memory: articulation, audition, and self-reference. 

Research by Forrin and MacLeod has demonstrated that reading aloud is better for memory than reading silently, writing, or hearing another person speak aloud. 

In the new study, however, the findings suggest that the production effect has a downside: When people anticipate reading out loud, they may have worse memory for information that they encounter before reading aloud. 

The researchers conducted four experiments with 400 undergraduate students and found that students have worse memory for words that they read silently when they anticipate having to read upcoming words aloud (compared to when they anticipate having to read upcoming words silently).

"Our results show that performance anticipation may be detrimental to effective memory encoding strategies," says Forrin. "Students frequently have upcoming performances--whether for class presentations or the expectation of class participation."

"We are currently examining whether the anticipation of those future performances reduces students' learning and memory in the classroom."

One strategy to avoid pre-performance memory deficits, says Forrin, is "try to get your performance over with by being the first student in class (or employee in a meeting) to present. After that, you can focus on others' presentations without anticipating your own."
