Question: What is the difference between explicit memories and implicit memories? Explicit memories (like semantic memory for facts and meaning and episodic memory for events and experiences in a person's life) involves consciously recalling information and being aware of that information. With implicit memories (procedural memory for motor tasks or priming, which biases responses), the memory still affects behavior, but individuals are not conscious of the effects of the memory, or are unable to verbally describe the memory. Why are episodic memories sometimes unreliable? People may lack a structure for remembering the episodic memory, and so the sequence of the memory may be distorted. Memories can be overwritten by suggestion, or confused with other memories due to retroactive inhibition or interference. People may not have the right cues available to properly recall information. Why does chunking help to increase the capacity of short-term memory? Chunking allows short-term memory to use the structures from long-term memory and thus a greater amount of information can be held in the short-term store - the same number of slots are available, but the amount of information in each slot my be increased. How might working memory be implemented in the brain? There seem to be individual neurons that continue to fire at higher rates after the presentation of a stimulus. This firing occurs for a much longer period of time than is required to process the information. (FROM 2/8 LECTURE): What is retroactive interference (this is called retrograde inhibition in the text)? Retroactive interference occurs when newly learned information interferes with or inhibits information that you learned previously. What is a Hebbian cell assembly made up of? A Hebbian cell assembly is made up of a number of cells that are interconnected and fire in some pattern (over time and space = spatiotemporal). In defining a Hebbian cell assembly, it is also important to note which cells are not firing as part of a given pattern. According to the dual trace model, how are memories related to the stimulus in the world and the original experience of that stimulus? The way that the experience of the world is coded (in terms of what neurons fire when) is likely to be an abstract representation of the
