which one of the two types of explicit memory contains concepts, meanings of words, and facts?
semantic memory
semantic memory is one of the two types of explicit memory (or declarative memory) (our memory of facts or events that is explicitly stored and retrieved). semantic memory refers to general world knowledge that we have accumulated throughout our lives. this general knowledge (facts, ideas, meaning and concepts) is intertwined in experience and dependent on culture. semantic memory is distinct from episodic memory, which is our memory of experiences and specific events that occur during our lives, from which we can recreate at any given point. for instance, semantic memory might contain information about what a cat is, whereas episodic memory might contain a specific memory of petting a particular cat. we can learn about new concepts by applying our knowledge learned from things in the past. the counterpart to declarative or explicit memory is nondeclarative memory or implicit memory.
semantic memory
explicit memory, or declarative memory, is the intentional recall of past events or learned information and is a discipline of ltm. explicit memory includes memory for remembering a specific event, such as dinner the week prior, or information about the world, such as the definition for explicit memory. when an anxious state is provoked, percentage recall on explicit memory tasks is enhanced. however, this effect is only present for emotionally associated words. stress hormones influence the processes carried out in the hippocampus and amygdala which are also associated with emotional responses. thus, emotional memories are enhanced when stress is induced, as they are both associated with the same areas of the brain, whereas neutral stimuli and stress are not. however, enhancement of explicit memory depends on the time of day. explicit memory is enhanced by stress when assessed in the afternoon, but impaired when assessed in the morning. basal cortisol levels are relatively low in the afternoon and much higher in the morning, which can alter the interaction and effects of stress hormones.
