What is the primary difference between short-term memory and working memory?

Short-term memory is the passive retention of information held temporarily, while working memory actively manipulates information currently in short-term memory.

What are the three distinct memory systems in Atkinson and Shiffrin's Modal Model of Memory?

Sensory store, short-term store (working memory), and long-term store (long-term memory).

What role does the prefrontal cortex play in working memory?

The prefrontal cortex is primarily responsible for keeping information active and manipulating it according to current goals.

What is the purpose of rehearsal in verbal short-term memory?

Rehearsal is necessary to retain sequences of acoustic or speech-based items in short-term memory for later transfer to long-term memory.

What was the main finding of the Ranganath study regarding color bias in visual working memory?

The study found that there are stimulus-specific biases in delayed estimation of color, with some colors being reported more frequently than others.

How do mood and context affect memory performance according to Baddeley's research?

Memory performance is better when the learning and testing contexts are the same, and mood during testing can influence recall efficacy.

What are the two major categories of long-term memory?

Declarative memory (explicit) and non-declarative memory (implicit).

How does the hippocampus contribute to declarative long-term memory according to Kandel's findings?

The hippocampus is essential for the encoding, consolidation, and retrieval of declarative memories, particularly recent ones.

What phenomenon describes the memory retrieval of recent memories being impaired while remote memories remain intact?

Temporally graded retrograde amnesia.

What happens to memory traces over time according to Systems Consolidation Theory?

Memory traces become reorganized and represented in the cortex, becoming independent of the hippocampus for retrieval.

What is the difference between implicit and explicit memory?

Implicit memory is unconscious and involves skills and conditioned responses, while explicit memory involves conscious recollection of facts and events.

What is the role of the amygdala in memory?

The amygdala is involved in the emotional aspects of memory, particularly in forming memories related to fear and pleasure.

What is chunking in the context of memory?

Chunking is a strategy that involves grouping information into larger, meaningful units to enhance short-term memory retention.

What is the effect of serial position on memory recall?

The serial position effect demonstrates that people tend to remember the first (primacy effect) and last items (recency effect) in a list better than those in the middle.

How does sleep affect memory consolidation?

Sleep plays a crucial role in memory consolidation by helping to stabilize and integrate newly learned information into long-term memory.

What is the function of the basal ganglia in memory?

The basal ganglia are involved in the formation and retrieval of procedural memories, such as habits and skills.

What is maintenance rehearsal?

Maintenance rehearsal involves repeatedly verbalizing or thinking about information to keep it in short-term memory.

How can mnemonic devices improve memory?

Mnemonic devices enhance memory recall by creating associations or using patterns to facilitate retention and retrieval of information.

What is long-term potentiation (LTP)?

Long-term potentiation is a persistent strengthening of synapses based on recent patterns of activity, which is thought to be a cellular mechanism underlying learning and memory.

What is the role of the cerebellum in memory?

The cerebellum is crucial for the formation of procedural memories and motor learning, coordinating movement and motor skills.

What is encoding in the context of memory?

Encoding is the process of converting information into a form that can be stored in memory.

What is the difference between retroactive and proactive interference?

Retroactive interference occurs when new information interferes with the recall of older information, while proactive interference happens when prior learning disrupts the learning of new information.

What is the method of loci?

The method of loci is a mnemonic technique that involves visualizing items to be remembered in specific locations along a familiar path.

How does interference theory explain forgetting?

Interference theory suggests that forgetting happens because other information competes with the information we want to remember.

What effect does overlearning have on memory?

Overlearning enhances memory retention and makes recall easier, as it reinforces the learned information beyond initial mastery.

How does visual imagery aid in memory retention?

Visual imagery aids memory by creating mental pictures that enhance the association between the information and its representation in memory.

What role does the thalamus play in memory processing?

The thalamus acts as a relay station for information traveling to and from the cerebral cortex, playing a crucial role in processing sensory information before it reaches memory storage.

What is the significance of the spacing effect in memory?

The spacing effect refers to the phenomenon where information is better retained when study sessions are spaced out over time rather than crammed into a single session.

What is the role of the dorsolateral prefrontal cortex in working memory?

The dorsolateral prefrontal cortex is involved in the manipulation and updating of information in working memory, particularly for complex tasks.

How does emotion influence memory retention?

Emotions can enhance memory retention for significant events, as heightened emotional arousal activates the amygdala, which aids in memory consolidation.

What is the difference between episodic and semantic memory?

Episodic memory is the recollection of specific events or experiences in time and space, while semantic memory is the general knowledge about facts and concepts.

How does context-dependent memory work?

Context-dependent memory refers to the improved recall of specific information when the context present during encoding matches the context during retrieval.

What is the role of sleep in the encoding process?

Sleep facilitates the encoding process by allowing the brain to organize and integrate information from the day, strengthening memory connections.

What is the concept of decay in memory theory?

Decay theory posits that memory traces weaken over time if not accessed or rehearsed, leading to forgetting of the information.

What is an example of a procedural memory?

An example of procedural memory is riding a bicycle, which involves skills learned through practice and is performed without conscious recall.

How do false memories occur?

False memories can occur when the brain reconstructs memories inaccurately, often influenced by external information, suggestion, or misinformation.
