How does decay affect memories?
List 2 ways
1) A memory’s activations fade, but the memory itself is intact (stored & available but inaccessible) as activation levels diminishes over time
2) The memory itself and its elements (i.e., its associations) degrade along with its activity level
How can trace decay be explained on a biological basis?
List 2 ways
1) Synaptic connections degrade and neurons die as time goes by = Memories may die or fade in the same way
2) Neurogenesis (growth of new neurons, esp in the hippocampus = structure is remodeled and its connections are gradually modified, detrimental to retain memory
How can Neurogenesis (growth of new neurons) be good for memory?

List 2 points
1) Ps clearly recalled the examples that they practiced quite well
2) But also recall the remaining unpracticed examples (e.g., FRUIT-BANANA), compared to unpracticed items from baseline categories that are also studied, but none of whose examples receive retrieval practice (e.g., DRINKS-SCOTCH).
Simply = Non practiced items had a substantial increase in forgetting compared to the control group
