8.3 Problems with Memory — Your Memory Is Not a Video Camera | Psychology 2e

• Understand memory is like an editable Wikipedia page, not a video recording.
• Learn amnesia is a profound loss of long-term memory from trauma or disease.
• Understand retrograde amnesia as the inability to retrieve memories before trauma.
• Learn anterograde amnesia is the inability to form new memories after trauma.
• Discover how patient HM could form new procedural memories despite anterograde amnesia.
• Differentiate between initial memory creation and the act of recalling it.
• Learn how recalling memories makes them unstable and susceptible to external suggestions.
• Understand that high stress and trauma can make memories more fragmented and error-prone.
• See how public suggestion led to widespread false eyewitness accounts in a crisis.
• Learn how subtle reinforcement can turn an uncertain memory into absolute certainty.
• Understand how avoiding suggestibility helped preserve a crucial, accurate memory.
• See how a single verb can alter memory, even inventing details like broken glass.
• Explore the debate on whether traumatic memories can be truly repressed and recovered.
• See how leading questions can induce false memories in highly suggestible young children.
• Introduction to Daniel Schacter's categories of everyday memory failures.
• Understand encoding failure as not initially learning or storing information.
• Learn that memories degrade over time if not accessed, known as transience.
• Understand absent-mindedness as a failure of attention preventing memory formation.
• Learn blocking is when encoded memories are temporarily inaccessible, like tip-of-the-tongue.
• Understand misattribution as remembering information but losing its source or context.
• Learn persistence is when the brain involuntarily forces critical memories into working memory.
• Understand interference as multiple memories actively competing, hindering recall.
• Discover how memory naturally distorts past events to enhance one's own role.

Memory feels like a reliable recording, but Section 8.3 of Psychology 2e reveals just how fragile and reconstructive it really is. From catastrophic amnesia caused by physical trauma to the subtle ways a single word can permanently rewrite what we think we witnessed, this lesson explores the full spectrum of memory failure. Along the way, real cases — including Ronald Cotton's wrongful conviction and the DC sniper investigation — show how high the stakes of faulty memory can be. In this video: • Retrograde vs. anterograde amnesia explained, with the landmark case of patient H.M. and how procedural memory survives hippocampal damage • How memory reconstruction (reconsolidation) makes every recalled memory vulnerable to alteration by new information or suggestion • The DC sniper case and the Ronald Cotton wrongful conviction as real-world examples of suggestibility and eyewitness misidentification • Elizabeth Loftus's misinformation effect paradigm — how changing one verb ('smashed' vs. 'contacted') caused participants to falsely remember broken glass • The controversy over repressed and recovered memories, including the Ceci and Brooks toddler study demonstrating how leading questions plant false memories • Daniel Schacter's Seven Sins of Memory — covering encoding failure (the penny test), transience and the Ebbinghaus forgetting curve, absentmindedness, blocking, misattribution, persistence, and interference • Egocentric bias: how the brain rewrites personal history to cast ourselves as the hero, distorting our own autobiographical memory #Psychology #OpenStax #Memory #CognitivePsychology OpenStax Content adapted from "OpenStax Psychology 2e", by OpenStax licensed under CC BY 4.0.
