L3: Memory Flashcards
Describe Atkinson & Shiffrin (1968) Multi-store Model of Memory (MSM)
- involves three memory stores: sensory memory, STM & LTM
- Information flows from sensory memory to STM through attention and rehearsal, and from STM to LTM through encoding and consolidation.
What was the method used in Sperling’s (1960) study on sensory memory?
- Sperling used the partial report procedure, where participants were shown an array of letters and heard a tone that cued them to recall a specific row of letters.
- Result: Participants could briefly recall more items from the cued row, suggesting the existence of iconic memory (visual sensory memory).
What is iconic memory?
- a type of sensory memory that retains visual information for a very brief duration, typically decaying in less than a second
What is echoic memory?
- a type of sensory memory that involves auditory information. It retains auditory stimuli for a short period, usually decaying in about 5 seconds
What was the method used in Tulving & Thomson’s (1973) study on memory retrieval cues?
- Tulving & Thomson examined retrieval cues by having participants learn word pairs and providing cues during recall.
Result: Participants showed improved recall when provided with appropriate retrieval cues, suggesting the importance of context in memory retrieval.
What was the method used in Godden & Baddeley’s (1975) study on context-dependent memory?
- Godden & Baddeley investigated context-dependent memory by having divers learn and recall words underwater or on land.
- Result: Participants showed better recall when the encoding and retrieval contexts matched, demonstrating the influence of context on memory
What was the focus of Brown & Kulik’s (1977) study on flashbulb memory?
- Brown & Kulik explored flashbulb memory, which refers to vivid and emotionally charged memories of significant events.
- Result: They found that flashbulb memories were well-preserved over time and associated with strong emotions
How did Loftus & Palmer (1974) examine the influence of leading questions on memory recall?
- Loftus & Palmer presented participants with videos of car accidents and asked about the car’s speed using different verbs.
- Result: The wording of the question affected participants’ estimates of the car’s speed, demonstrating the reconstructive nature of memory
What did Wells et al. (1998) study on eyewitness misidentification reveal?
- Wells et al. investigated the unreliability of eyewitness memory in legal contexts.
- Result: The research highlighted the significance of eyewitness misidentification in wrongful convictions
What did Nader et al. (2000) discover in their study on memory reconsolidation?
- Nader et al. investigated memory reconsolidation in rats by retrieving and updating memories.
- Result: The study showed that memories become temporarily unstable during retrieval and can be updated before reconsolidation
What aspect of memory encoding did Craik et al. (1996) examine in their study?
- Craik et al. examined memory encoding in older adults, focusing on the level of attention during encoding.
- Result: Older adults’ memory performance was influenced by the level of attention they paid to information during encoding
What phenomenon did Glanzer & Cunitz (1966) explore in their memory study?
- Glanzer & Cunitz explored the serial position effect by presenting participants with a list of words.
- Result: Participants were more likely to remember words presented at the beginning (primacy effect) and end (recency effect) of the list.
What aspect of memory did Underwood (1957) study in his research?
- Underwood’s study on proactive interference had participants learn multiple lists of words.
- Result: Participants’ recall of newly learned information was affected by interference from previously learned information
What are the key elements of memory?
- Encoding, Storage, and Retrieval.
- Atkinson & Shiffrin’s (1968) model of memory, known as the “multi-store model,” proposes that memory involves three main components: sensory memory, STM & LTM
How does memory encoding work?
- involves the process of converting sensory information into a form that can be stored in memory
- Atkinson & Shiffrin’s model suggests that info from the sensory registers enters short-term memory through attention, where it is processed further
What is iconic memory, and how long does it typically last?
- Iconic memory is a type of sensory memory that pertains to visual information.
- It retains visual stimuli for a very brief duration, usually decaying in less than a second.
- Sperling (1960) conducted a classic study on iconic memory using a partial report procedure.
What is echoic memory, and how long does it typically last?
- Echoic memory is a type of sensory memory that involves auditory information.
- It retains auditory stimuli for a short period, usually decaying in about 5 seconds.
How is memory retrieval affected by context and cues?
- Memory retrieval can be influenced by the context in which the information was encoded and the presence of cues that trigger associations with the stored memory.
- Tulving and Thomson (1973) demonstrated the importance of retrieval cues in accessing specific information from memory
What is the role of the central executive in Baddeley’s working memory model?
- The central executive is an attentional system that coordinates and controls plans of action and output
What is the function of the visuospatial sketchpad in working memory?
- The visuospatial sketchpad briefly stores visual and spatial information for further manipulation
What does the phonological loop handle in Baddeley’s working memory model?
- The phonological loop allows for saying the information back to yourself (articulatory rehearsal) and handles auditory information
What is the purpose of the episodic buffer in working memory?
- is a temporary storage space where information from long-term memory can be integrated into working memory
What is the role of the hippocampus in memory?
- s crucial for memory formation and consolidation
- It helps transfer information from short-term memory to long-term memory.
- Studies on patients with hippocampal damage, such as patient H.M. (Scoville & Milner, 1957), have provided significant insights into the role of the hippocampus in memory
How does the process of memory storage work?
- involves maintaining encoded information over time. According to Atkinson & Shiffrin’s model, information can be transferred from STM to LTM through rehearsal
What is sensory memory?
- the brief retention of sensory information in its original sensory form (e.g., visual, auditory) before it is processed further
- sperling (1960) conducted a study on the capacity and duration of sensory memory using the whole report and partial report procedures
