Cognitive Psychology: Learning, Organization, and Memory Retrieval

Information Organization in Storage

  • General Principle: Structuring or restructuring information while in storage significantly enhances memory; highly organized information is easier to store and recall.
  • Bousfield(1953)Bousfield (1953): Conducted a study using a 6060-item list consisting of 1515 words from each of 44 categories (animals, personal names, vegetables, and professions) presented in random order. Participants tended to recall items in category groupings, implying they reorganized the lists during presentation.
  • Mandler(1967)Mandler (1967): Suggested that organizing memory into categories is similar to MillerMiller's chunking and follows a hierarchical structure.
  • Bower, Clark, Lesgold, & Winzenz (1969): Compared recall for 112112 words presented in either a meaningful hierarchical organization or a random organization.   - Trial 1: Organized (65%65\%) vs. Random (18.3%18.3\%).   - Trial 4: Organized (100%100\%) vs. Random (62.5%62.5\%).

Imagery in Memory

  • Dual-Coding Hypothesis (Paivio,1971,1990Paivio, 1971, 1990): Items that are imageable can be encoded in memory twice (e.g., "snow" is high-imageable, whereas "trust" is low-imageable).
  • Paired-Associate Learning (Schnorr & Atkinson, 1969): Participants learned word pairs (e.g., elephant–book). Results showed 80%80\% immediate recall for associates studied using imagery compared to 40%40\% for those studied without imagery.

Encoding Specificity

  • Core Definition: Information present during encoding determines the effectiveness of retrieval cues; items are encoded within a context of meanings and environmental factors.
  • Mood-Congruent Memory: It is easier to learn and recall "happy terms" when in a good mood, as the mood serves as a retrieval cue.
  • Thomson & Tulving (1970): Investigated how processing at study influences test performance using three encoding conditions (no associate, strong associate like "CHAIR–DESK", and weak associate like "CHAIR–GLUE").   - Findings indicated that the effectiveness of a retrieval cue depends heavily on the specific encoding condition. For items encoded with a weak associate, the weak cue at test was more effective than a strong cue or no cue.

Mnemonic Devices and Memory Improvement

  • Mnemonics: These are successful because they provide structure, create durable memories, and offer retrieval cues.
  • Strategies for Improvement:   - Rehearsal: Repeatedly processing the information.   - EbbinghausEbbinghaus Principles: Utilizing overlearning and distributed practice.   - Attention: Maintaining focus during the middle and end of lectures.   - Interference: Minimizing distractions and competing information.   - Acronyms and Acrostics: Using tools like "I SCREEM" (implicit, semantic, recently-acquired, explicit, episodic).   - Organization: As demonstrated by BowerBower et al. (1969)(1969).   - Imagery: Utilizing techniques like the Method of Loci.   - Distinctiveness: Leveraging the vonRestorffvon Restorff effect.   - Focus on Meaning: Prioritizing semantic understanding.   - Associations: Using mental links (e.g., "A hippo never forgets").   - Retrieval Cues: Making retrieval easier as shown by Tulving & Pearlstone (1966), where participants recalled 62%62\% with category cues versus 40%40\% without cues.
