Study Notes

The Concept of Learning

  • The second meaning of 'learning' refers to the improvement in performance of a particular task over time.

Memory Systems

  • Memory systems are defined as psychological constructs that account for a whole set of empirical results.
  • An advantage of using psychological constructs like memory systems is that they can account for a whole set of empirical results.
  • Memory systems mediate performance in specific memory tasks, but most tasks are sensitive to the contributions of more than one memory system.
  • Drawing inferences from memory tasks about the operation of memory systems requires evidence from multiple tasks.

Memory and Consciousness

  • H.M.'s case demonstrated that memories associated with consciousness are not dependent on medial temporal lobe regions.
  • The ability of remembering personally experienced events is not dependent on whether recall is spoken or written.

Historical Contributions

  • Ancient Greek ideas contributed to the notion of memory systems.
  • One of the most important advances in the twentieth century was the development of the concept of memory systems.

Research and Findings

  • Researchers assumed that tasks impaired by medial temporal lobe damage in non-human animal models measured types of memory similar to those impaired in patient H.M.
  • Psychologists found evidence of memory retention in normal human participants during the 1970s.
  • The concept of short-term memory was expanded into the notion of working memory.
  • Retaining information across delays of seconds or minutes involves mechanisms fundamentally different from those used for retaining information across delays of hours, days, or weeks.
  • Psychologists found evidence of retaining information across delays of seconds or minutes.
  • Behavioral neuroscientists tried to achieve a better understanding of the role of consciousness in memory, inspired by the case of patient H.M.
