1 Effects of Emotions and Cognitive Load on Memory Presented at the University of California, Irvine by Namrata Mahajan May 14, 2005

3 Memory is Important!!! - Memory is important to be able to function in everyday life!  Riding a bicycle  Counting change  Driving  Remembering the name of someone you just met

4 What is Memory? Memory is the ability to use or to remember information that was previously encoded or processed (Ericsson & Chase, 1982).

5 Memory and Emotions  Mood Congruent Theory- We remember events that match our current mood. Studies show that emotionally charged events are remembered better than ordinary, neutral events (e.g. Christianson, 1992).

6 Memory & Cognitive Load Cognitive Load- The “total amount of mental activity imposed on working-memory at an instance in time” (Cooper, 1998). - Excessive cognitive loads affect memory and make learning more difficult. Working-Memory  Long-Term Memory

7 Hypotheses  H 1 : Participants will remember mood-congruent better than mood-incongruent information.  H 2 : Participants without cognitive load will remember information better than those with cognitive load.  H 3 : Participants under both an emotional condition and cognitive load will remember more mood- congruent information.

8 Methods

9 1.Demographics (e.g. age, ethnicity etc). 2.Emotion Elicitation Task  e.g. “Please describe three to five things that make you the most happy.” 3.Learning Task (30 slides with or without cognitive load).  10 happy  10 sad  10 neutral 4. Distracter Activity 5. Recognition Task 6. Debriefing

20 Results

21 Participants - Gender N=200

22 Participants - Ethnicity

23 H 1 : Participants will remember mood-congruent slides better than mood-incongruent slides. Happy Slides Sad SlidesNeutral Slides Happy+-- Sad-+- Neutral--+

24 H 1 : Participants will remember mood-congruent slides better than mood-incongruent slides. Happy Slides Sad SlidesNeutral Slides Happy+-- Sad-+- Neutral--+

25 Method Each participant given score out of a possible 20 20 = no false positives and no mistakes

32 Mean Number of Slides Accurately Recognized Although not significant, there is a trend for participants without cognitive load to have higher accuracy rates than participants with cognitive load. Cognitive Load Mean Number of Slides Accurately Recognized

33 H 3 : Participants under both an emotional condition and cognitive load will remember more mood congruent slides. Happy Slides Sad Slides Neutral Slides Happy+++ Sad+++ Neutral+++ No LoadLoad Happy Slides Sad Slides Neutral Slides Happy+-- Sad-+- Neutral---
