Study Notes
Memory Overview
- Memory involves the retention, retrieval, and usage of information about stimuli, images, events, ideas, and skills after the original information is gone.
- Sensory memory retains information briefly, allowing for perception continuity of stimuli like facial images.
Types of Memory
- Sensory Memory: Captures information for seconds or fractions of a second, such as the afterimage of a flash.
- Short-Term Memory (STM): Holds information for about 10 to 15 seconds without rehearsal; can contain 5 to 7 items.
- Long-Term Memory (LTM): Stores information for extended periods, from minutes to a lifetime.
Memory Model by Atkinson and Shiffrin
- Proposes three structural features: sensory memory, short-term memory, and long-term memory.
- Introduces control processes, dynamic processes that can differ between tasks, such as rehearsal to retain information in STM.
Encoding and Retrieval
- Encoding: The process of storing information in LTM.
- Retrieval: The process of bringing stored information back to mind.
Sensory Memory Details
- Retains sensory stimulation effects for a very brief period.
- Persistence of Vision: Continued perception of visual stimuli post-exposure; crucial for experiencing films uninterrupted.
Sperling's Experiment on Sensory Memory
- Whole Report Method: Participants average recalled 4.5 out of 12 letters shown briefly.
- Partial Report Method: Enhanced recall when cued instantly by tone, demonstrating sensory memory's capacity.
- Delayed Partial Report Method: Retention decreases when a delay is added.
Iconic and Echoic Memory
- Iconic Memory: Visual memory retains information for a fraction of a second.
- Echoic Memory: Auditory memory persists for a few seconds, allowing immediate recollection of sounds.
Short-Term Memory Characteristics
- Functions as a temporary storage for current thoughts and knowledge.
- Duration of STM confirmed to be 15 to 20 seconds through studies by Brown, Peterson, and Peterson.
Baddeley's Working Memory Model
- Phonological Loop: Stores verbal and auditory information; affected by phonological similarity and word length effects.
- Visuospatial Sketch Pad: Manages visual and spatial information; involved in visual imagery and mental rotation tasks.
- Central Executive: Coordinates the use of the phonological loop and visuospatial sketch pad; regulates attention and task-switching.
Effects on Memory
- Articulatory Suppression: Reduces memory capacity by blocking rehearsal through repeated irrelevant sounds.
- Mental Rotation: Demonstrates the visuospatial sketch pad's ability to manipulate images mentally.
Additional Components of Working Memory
- Episodic Buffer: Provides extra capacity by linking LTM with working memory, enabling chunking and meaningful associations.
Impact of Prefrontal Cortex Damage
- Damage leads to impaired attention control and altered personality traits, as evidenced by Phineas Gage's case.
- Frontal lobes are crucial for planning and social behavior, illustrating their role in memory function.
Conclusion
- Working memory involves dynamic interaction between its components and plays a critical role in handling and processing information in everyday situations.
