memory is important
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
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
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
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
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

H2 : Participants without cognitive load will remember slides better than those with cognitive 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.
