Cognitive Psychology: Learning, Organization, and Memory Retrieval
- General Principle: Structuring or restructuring information while in storage significantly enhances memory; highly organized information is easier to store and recall.
- Bousfield(1953): Conducted a study using a 60-item list consisting of 15 words from each of 4 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): Suggested that organizing memory into categories is similar to Miller's chunking and follows a hierarchical structure.
- Bower, Clark, Lesgold, & Winzenz (1969): Compared recall for 112 words presented in either a meaningful hierarchical organization or a random organization.
- Trial 1: Organized (65%) vs. Random (18.3%).
- Trial 4: Organized (100%) vs. Random (62.5%).
Imagery in Memory
- Dual-Coding Hypothesis (Paivio,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% immediate recall for associates studied using imagery compared to 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.
- Ebbinghaus 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 Bower et al. (1969).
- Imagery: Utilizing techniques like the Method of Loci.
- Distinctiveness: Leveraging the vonRestorff 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% with category cues versus 40% without cues.
