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
What is Memory? Memory is the ability to use or to remember information that was previously encoded or processed (Ericsson & Chase, 1982).
Memory and Emotions Studies show that emotionally charged events are remembered better than ordinary, neutral events (e.g. Christianson, 1992). • Mood Congruent Theory- We remember events that match our current mood.
Memory & Cognitive Load • Cognitive Load- The “total amount of mental activity imposed on working-memory at an instance in time” (Cooper, 1998). Working-Memory Long-Term Memory - Excessive cognitive loads affect memory and make learning more difficult.
Hypotheses • H1 : Participants will remember mood-congruent better than mood-incongruent information. • H2 : Participants without cognitive load will remember information better than those with cognitive load. • H3 : Participants under both an emotional condition and cognitive load will remember more mood- congruent information.
Methods • Demographics(e.g. age, ethnicity etc). • Emotion Elicitation Task • e.g. “Please describe three to five things that make you the most happy.” • Learning Task(30 slides with or without cognitive load). • 10 happy • 10 sad • 10 neutral • Distracter Activity • Recognition Task • Debriefing

Participants - Gender N=200
H1 : Participants will remember mood-congruent slides better than mood-incongruent slides.
H1 : Participants will remember mood-congruent slides better than mood-incongruent slides.
Method • Each participant given score out of a possible 20 • 20 = no false positives and no mistakes
H1 : Participants will remember mood-congruent slides better than mood-incongruent slides.
H1 : Participants will remember mood-congruent slides better than mood-incongruent slides.
H1 : Participants will remember mood-congruent slides better than mood-incongruent slides.
No Load Load H2 : Participants without cognitive load will remember slides better than those with cognitive load.
Mean number of slides accurately recognized No Load Load
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. Mean Number of Slides Accurately Recognized Cognitive Load
H3 :Participants under both an emotional condition and cognitive load will remember more mood congruent slides. No Load Load
H3 :Participants under both an emotional condition and cognitive load will remember more mood congruent slides. No Load Load
Mean number of slides accurately recognized No Load Load
Mean number of slides accurately recognized No Load Load
Possible Explanations and Future Directions • Ceiling Effects • Number of Slides • Timing • Distracter Activity • Emotion Eliciting Activity
