Study Notes

Memory Overview

Kartini Ilias (PhD), Senior Lecturer/Clinical Psychologist, Faculty of Health Sciences, UiTM
Lecture topics include: The Nature of Memory, Forgetting, Biological Bases of Memory, Memory and the Criminal Justice System, Using Psychology to Improve Our Memory

The Nature of Memory

Memory: An internal record or representation of some prior event or experience.
Constructive process: Actively organizing and shaping information as it's processed, stored, and retrieved.

Models of Memory

Information Processing Model: Memory is analogous to a computer, with encoding, storage, and retrieval stages.
Parallel Distributed Processing Model (PDP): Memory involves a vast network of interconnected units (neurons) that process information simultaneously. Also called the connectionist model.
Levels of Processing Model: Memory retention depends on the depth of mental processing. Deep processing enhances memory retention.
Traditional Three-Stage Model: Memory comprises sensory memory (brief impressions), short-term memory (temporary holding), and long-term memory (lasting storage).

Encoding, Storage, and Retrieval (Based on Information Processing Model)

Encoding: The process of taking in information (visual, auditory, semantic).
Storage: Information is stored in short-term or long-term memory, depending on attention and practice.
Retrieval: Accessing the stored information when needed, influenced by rehearsal/practice. Quick if information is rehearsed.

Application in Daily Life (Across Models)

Encoding effectively (attention, relating to prior knowledge) improves storage of information.
Regular retrieval practice improves memory recall in real-life.
PDP model explains how smells or songs can trigger childhood memories, or multitasking ability.
Level of processing model: deeper processing (meaningful connections, relating info to other knowledge, visualization) enhances retention.

Biological Bases of Memory

Changes in neurons through long-term potentiation:
- Repeated synapse stimulation strengthens the synapse.
- Ability of a neuron to release neurotransmitters can increase or decrease.
Changes in hormones affect various brain structures.
Flashbulb memories: Vivid images of emotionally significant events.
Memory is distributed throughout the brain, not just in the cortex.
Brain structures involved: cerebral cortex, thalamus, basal ganglia, hippocampus, amygdala, cerebellum

Biological Causes of Memory Loss

Amnesia: loss of memory as a result of serious brain injury or trauma, including:
- Retrograde amnesia (loss of past memories).
- Anterograde amnesia (inability to create new memories).
Alzheimer's disease: Progressive mental deterioration, characterized by severe memory loss.

Memory and the Criminal Justice System

Eyewitness accounts: Often persuasive but can be flawed.
Repressed memories: Debate on the accuracy of recovered memories.

Using Psychology to Improve Memory

Strategies for improving memory include attention management, rehearsal, organization, combating the serial position effect, effective time management, encoding specificity principle, self-monitoring, overlearning, and mnemonic devices.

Forgetting

Ebbinghaus: Forgetting occurs most rapidly immediately after learning; relearning takes less time.
Theories of forgetting include decay, interference, motivated forgetting, encoding failure, and retrieval failure.
Interference: Retroactive (new information interferes with old) and Proactive (old information interferes with new).
Serial position effect: People tend to remember items at the beginning and end of a list better than those in the middle.
Source amnesia: Forgetting the true source of a memory.
Sleeper effect: Initially discounting unreliable sources, but later believing them potentially because the source is forgotten.
Spacing of practice: Distributed practice is more effective than massed practice.

Short-Term Memory (STM) and Working Memory

STM: Holds about 5–9 items for about 30 seconds.
Increased capacity: Through chunking.
Capacity and duration enhanced through maintenance and elaborative rehearsal.
Working memory: Active processing of information, not just passive storage. Visuospatial sketchpad, phonological loop, and central executive.

Long-Term Memory (LTM)

Relatively permanent memory storage with unlimited capacity.
Improving LTM: Organization, elaborative rehearsal, and retrieval cues (recognition and recall)

Types of Long-Term Memories

Explicit/Declarative memories: conscious recall. Includes semantic memory (general knowledge) and episodic memory (personal experiences).
Implicit/Nondeclarative memories: No conscious recall. Includes procedural memory (motor skills), classical conditioning, and priming.
