What is an example of semantic memory?

Semantic memory is a category of long-term memory that involves the recollection of ideas, concepts and facts commonly regarded as general knowledge. Examples of semantic memory include factual information such as grammar and algebra.

Is the hippocampus involved in semantic memory?

With the perspective of time and this critical review, we arrive at the interpretation that the hippocampus does indeed make necessary contributions to semantic memory.

What does semantic memory mean in psychology?

Introduction. Semantic memory refers to our general world knowledge that encompasses memory for concepts, facts, and the meanings of words and other symbolic units that constitute formal communication systems such as language or math.

Does amnesia affect semantic memory?

Semantic amnesia is a type of amnesia that affects semantic memory and is primarily manifested through difficulties with language use and acquisition, recall of facts and general knowledge. A patient with semantic amnesia would have damage to the temporal lobe.

Are names semantic memory?

Semantic memory refers to a portion of long-term memory that processes ideas and concepts that are not drawn from personal experience. Semantic memory includes things that are common knowledge, such as the names of colors, the sounds of letters, the capitals of countries and other basic facts acquired over a lifetime.

Where is the semantic memory?

Semantic memory is sustained by relatively preserved lateral temporal lobes in AUD. Semantic memory refers to the memory of meaning, understanding, general knowledge about the world, and other concept-based knowledge unrelated to specific experiences.

What is a semantic network in memory?

A semantic network is a representation of memory that describes the organization of declarative facts and knowledge in the mind. A network consists of a set of nodes and a set of edges. Each node in the network denotes a concept in semantic memory, such as fish or purple.

What can affect semantic memory?

The left inferior prefrontal cortex (PFC) and the left posterior temporal areas are other areas involved in semantic memory use. Temporal lobe damage affecting the lateral and medial cortexes have been related to semantic impairments. Damage to different areas of the brain affect semantic memory differently.

Does semantic memory decline with age?

Age-related decline in episodic and semantic memory performance was found to be the consequence of declines in processing speed and executive functioning. The results suggest that at very old age, the impact of executive dysfunctions on episodic memory performance exceeds the influence of cognitive slowing.

At what age is memory the best?

When Do Mental Powers Peak?

• 18-19: Information-processing speed peaks early, then immediately begins to decline.
• 25: Short-term memory gets better until around age 25.
• 30: Memory for faces peaks and then starts to gradually decline.
• 35: Your short-term memory begins to weaken and decline.

Which is older semantic memory or episodic memory?

In relation to episodic memory, semantic memory is considered to be both a phylogenically and an ontologically older system. In fact, rather than arising as an independent evolutionary development, it is commonly assumed that episodic memory emerged as an add-on or embellishment to semantic memory ( Tulving, 2002 ).

How are the three types of encoding used in semantic memory?

Visual, acoustic, and meaning are the three main types of encoding used to commit information to semantic memory. Individuals may encode information to semantic memory through pictures or reading words and numbers, by repeatedly hearing the information, or by connecting the information to something else that has meaning in the memory.

Why is semantic memory independent of the context?

Semantic memory is independent of the context of learning and personal experiences like how we felt at the time the event was experienced or situational properties like time and place of gaining the knowledge. The level of consciousness associated with semantic memory is noetic because it is independent of context encoding and personal relevance.

When does a person lose their semantic memory?

But there are certain cases when semantic memory is lost. It happens in the case of semantic dementia where progressive neocortical degeneration is seen. The verbal stimuli are non-differential for such patients and changes in other modalities like odour and taste.
