  1. 1. INMI Symposium Discussion ICMPC 2012 Andrea Halpern Bucknell University Pennsylvania, USA
  2. 2. INMI and Memory
  3. 3. Similarities to “Flashbulb Memories” Generate… Vivid Autobiographical Extend in time Affective component Social aspects ◦ Memories include others ◦ Discussed with others Compelling memory experience
  4. 4. Dissimilar Flashbulbs INMI Single retrieval End cues beginning Limited number Many and variable◦ Shared in a culture ◦ Across and within people Distinctive trigger Triggers variable Associated with By and large pleasanttrauma
  5. 5. Less Well Understood…
  6. 6. Incidence Rate?Most report high incidenceHalpern & Bartlett (2011)◦ 41 diarists over 2 weeks 780 reports◦ Range = 2-57◦ Median = 1.7 per dayBut do methods select for respondents andreports?Embed in other tasks to reduce salienceand social desirability
  7. 7. Verification?Difficult to verifyVoluntary imagery◦ Control stimuli◦ Objective task Does third note of Happy Birthday rise or fall?Need correlates with INMINeed to induce. How?◦ Idiosyncratic, but…◦ Exposure◦ Musical characteristics
  8. 8. Possible Correlates?Behavioral◦ Effect on a second task◦ Continuous measurementPhysiological◦ Neural or peripheral◦ Neural correlates of voluntary imagery◦ Indices of repetition crucialLong time spans will be a challenge
  9. 9. Veridical?Rubin & Talarico (Psychological Sci, 2003)FBs no more accurate or durable than othermemories◦ Conflicts in memories among participants
  10. 10. How to measure veridicality in INMI?External pitch or tempo measureConsistency over repetitionsCongruence with recorded version◦ Even NMs can match to recordings and be somewhat consistent over time◦ Production or choose pitch/tempo
  11. 11. Unique to Music?Other temporally extended memories◦ Verbal or experientialH&B (2012)◦ 9/20 surveyed reported word earworms But only a few diary entries◦ Did not repeat◦ Sayings, movie quotes, cheer, advertisement◦ None unpleasantDesign survey/diary to elicit these
  12. 12. Relationship to Pathology?Hallucinations vs. imageryPossible intermediate states◦ Relation to aural and psychological issuesImportant to distinguish wanted fromunwantedFor latter, behavioral and pharmacologicalintervention◦ Yellow Submarine #2: “This song is starting to annoy me and I think I should memorize more words of it”.◦ #4: “I like the song but I dont know the lyrics and it keeps appearing in my head.”
  13. 13. Age and Cohort?Priming◦ Can increase with age◦ Decline of inhibition◦ So possible increase with age?Cohort/Generation◦ Continuous vs. periodic exposure to music
  14. 14. Thank You!
