Questions & Answers

Q: How can external sources influence our memories?

External sources, such as other people or news, can shape our memories by incorporating information into our recollections without our awareness, as seen in the study where participants falsely remembered getting lost in a shopping mall based on suggestions from psychologists.

Q: How does misattribution affect our memories?

Misattribution occurs when we attribute information from one context to another, leading to false memories. For example, participants in a study misattributed seeing a magnifying glass and imagining a lollipop, struggling to remember whether they actually saw them or only imagined them.

Q: Can personal opinions affect our memories?

Yes, research has shown that our current opinions, feelings, and experiences can bias our memories of how we felt in the past. This was demonstrated in a study where participants adjusted their recollections to align with their current stance on marijuana legalization.

Q: What impact can fallibilities in memory have in practical situations?

Fallibilities in memory can have significant real-world impacts. In police interrogations, leading questions can lead to incorrect identifications or unreliable confessions. In courtrooms, misattribution can result in inaccurate eyewitness testimony. In medical settings, prior diagnoses can bias a second physician's conclusions.
