Study Notes

Memory and its importance

Memory is crucial for recognizing people, remembering tasks, and performing everyday activities.
It provides us with a sense of self and situates us in time and space.
Loss of memory can significantly impact identity and relationships.
Memory is a constructive process that involves encoding, storage, and retrieval.
Sensory stimuli trigger memories, which are processed and stored in short-term and long-term memory.

Types of Memory

Sensory Memory: This is the initial stage where we interact with environmental information.
- Iconic Memory: Memory for what we see, lasts less than half a second.
- Echoic Memory: Memory for what we hear, lasts about three to four seconds.
Working Memory: This holds information that we are currently thinking about.
- Visuo-Spatial Sketchpad: Processes visual and spatial information.
- Phonological Loop: Processes verbal information, including words and numbers from both echoic and iconic memory.
- The Central Executive: Integrates information from both components into the Episodic Buffer, which connects to Long-term memory.
Long-Term Memory: This is the final stage where information is stored like files on a computer.
- Explicit (Declarative) Memory: Facts and events we can consciously recall.
  - Semantic Memory: Facts and general knowledge.
  - Episodic Memory: Personal experiences and events.
- Implicit (Non-Declarative) Memory: Skills and procedures performed without conscious thought.
  - Procedural Memory: How to perform tasks like riding a bike.
  - Priming: Previous experiences influencing the interpretation of current events.

Attention

Attention is the capacity or energy necessary to support information processing.
It involves alertness, ignoring distractions, attending to relevant information, and managing multiple sources of information.
Automatic Processing: Performs tasks with minimal demands on attentional capacity, often done unconsciously.
Effortful Processing: Requires full attentional capacity, leading to tiredness after prolonged periods of effortful processing.

Speed of Processing: How quickly and efficiently the early steps in information processing are completed.
- Declines at different rates for older adults, depending on the task and its difficulty level.
Processing Resources: The amount of attention needed for a particular situation. Older adults generally require more attention for complex tasks.
Selective Attention: Ability to distinguish relevant from irrelevant information. Older adults find it challenging to filter out irrelevant information.
Divided Attention: Ability to distribute attention across multiple sources of information. Older adults struggle with complex divided attention tasks.
Working Memory: Limited capacity, actively processes and holds information in mind.
- Rehearsal: Process of keeping information in working memory.
- Age-related decline: Spatial working memory declines more than verbal working memory.
- Factors influencing decline: Alertness levels, task order, and interference.
Long-Term Memory:
- Implicit Memory: Varies with age.
  - Decline in tasks involving learning sequences of information. No decline in learning spatial contexts.
- Explicit Memory:
  - Episodic Memory: Generally stable until age 55-60, with a steep decline from age 65.
  - Semantic Memory: Remains relatively stable throughout aging.
- Autobiographical Memory: Shows few age-related losses.
- Flashbulb Memories: Memories of personally traumatic events. It is difficult to measure age-related declines.
- False Memories: Older adults have difficulties separating misleading context from relevant context.

Prospective Memory

Remembering to perform a planned action in the future.
Time-based tasks show greater decline with age (self-initiated cues), while event-based tasks show minimal decline (given cues).

The 3 Ds of Mental Health and Ageing

Dementia: Progressive neurological disorder, impacting cognitive function, memory, thinking, and social abilities.
Depression: Mood disorder prevalent among older adults, characterized by persistent sadness, loss of interest, and physical symptoms.
Delirium: Acute, fluctuating state of confusion, often triggered by medical conditions, medication side effects, or substance withdrawal.
