Study Notes

Memory Theories

Independent variables can impact memory differently based on the type of memory test used.
Age-related differences: Older adults show decline in declarative memory but not in implicit memory tests (e.g., priming).
Memory is proposed to consist of different systems that operate independently (e.g., episodic, semantic, explicit, implicit).
Transfer-appropriate processing (TAP) posits that successful memory retrieval depends on the match of operations during encoding and retrieval.

Memory Systems

Memory is categorized into functionally distinct modules:
- Short term: Spatial and verbal.
- Long term: Procedural (implicit) and declarative (explicit: semantic and episodic).

Transfer Appropriate Processing

Performance improves when encoding and retrieval processes align.
Cognitive operations engaged during initial processing help guide successful memory retrieval.
Memory acts as a skill, limited in generalization—improvement in one area doesn’t assure success in others.
Encoding is a by-product of on-line processing with no dedicated encoding system, challenging traditional encoding/retrieval distinctions.

Data Driven (Perceptual)

Processing focuses on physical features of a stimulus; it varies with how an item (like a cat) is presented (visual vs. auditory).
This simplistic view of memory processes is likely inadequate and may evolve with future understanding.

Conceptually Driven (Semantic)

Processing targets an item's meaning rather than its physical attributes; tasks can vary based on meaning or structural features (e.g., counting letters).
Similar limitations as data-driven processing apply, warranting deeper exploration of memory functions.

Dissociations

TAP theory clarifies dissociations between explicit and implicit tests—explicit tests need conceptually driven processing, while implicit tests favor data-driven processing.
Manipulations affecting data-driven processing at study largely impact implicit tests, whereas those affecting conceptually driven processing impact explicit tests.

Jacoby (1983) Study

Participants read and generated words, followed by a recognition memory test.
Both types of items (read vs. generated) were tested; better recognition was observed for generated items.
Priming favored read items due to their visual presentation during the encoding phase.
This study exemplifies dissociation in memory tests, with TAP theory explaining the results through processing overlaps.

Perceptual Identification and Recognition

Perceptual identification relies on data-driven processing, favoring read conditions.
Recognition tests benefit from conceptually driven processing, showing better outcomes for generated conditions.

Behavioral Evidence

Measurement clusters should be based on data-driven or conceptually driven processing rather than explicit/implicit classifications.

Blaxton (1989) Insights

Findings support TAP theory, indicating memory clusters adhere to whether tasks employ data-driven or conceptually-driven processing.
Similar patterns to Jacoby were observed across various implicit and explicit tests.

Neurological Evidence

Successful recall is marked by overlaps in encoding and retrieval processes within specific brain regions.
Notable cortical reinstatement identified for effective recall.

Kahn et al. (2004) Neural Evidence

Neural activity during encoding paralleled that during retrieval, reinforcing the association of processing types across memory stages.

Limitations of TAP

Challenges exist at behavioral and neuropsychological levels:
- Deep processing enhances memory regardless of test type.
- Variations in retrieval practice affect memory outcomes.
- Generation versus revelation effects exhibit inconsistency with TAP predictions.
- Amnesic patients perform differently on explicit vs. implicit tests, questioning TAP applicability.

Summary of TAP Framework Modifications

TAP remains a foundational principle for understanding memory, but other factors like retrieval effort and trace elaboration affect recall.
The medial temporal lobe functions critically in linking events to contexts, illustrating the complexities of memory processes.

Final Summary

TAP unifies diverse data and predictions in memory research while exposing limitations in applying straightforward classifications. Amnesic patterns also suggest a need for a more nuanced understanding of cognitive processes beyond simple dichotomies.
