Answers

Multiple Choice:

  1. C) Hippocampus

  2. A) Encoding

  3. B) Sensory memory

  4. D) Serial position effects

  5. B) Semantic memory

True/False:

  1. False

  2. True

  3. True

  4. False (This describes retroactive interference.)

  5. False

Short Answer:

  1. Iconic memory is visual sensory memory lasting less than 1 second (e.g., briefly seeing a flash of light). Echoic memory is auditory sensory memory lasting 3-4 seconds (e.g., hearing a sound and briefly retaining it).

  2. Retrieval cues, such as environmental factors or words from the original learning context, help bring information to mind. Example: Studying in the same room where a test is taken can improve recall.

  3. Patient HM had his hippocampus removed, resulting in severe anterograde amnesia. He could not form new explicit memories but could learn procedural tasks, demonstrating a distinction between explicit and implicit memory systems.

  4. Transience: Memories fade over time. Absentmindedness: Lack of attention leads to forgetting. Blocking: Temporarily unable to recall information ("tip of the tongue").

  5. Loftus & Palmer's study showed that memory can be influenced by misleading information. The verb used to describe a car accident affected participants' recall of the event, leading to false memories of glass on the ground.

Matching:

  • A) Episodic memory → 2

  • B) Procedural memory → 4

  • C) Absentmindedness → 3

  • D) Blocking → 1

  • E) Schema → 5

Essay:
(The essay should include a detailed explanation of explicit and implicit memory, using examples like declarative knowledge for explicit memory and procedural tasks for implicit memory. Cases of HM and KC highlight the roles of the hippocampus and distinctions between episodic, semantic, and procedural memory.)
