Question

Timothy Salthouse tested both ____ and ____ in adults of various ages

- He concluded that the loss of speed occurs at the level of the ____ and not in the ____
- physiological changes in ____ and the continuation of the loss of ____, may be the cause of changes in memory.

Answer 1

Timothy Salthouse concluded that cognitive slowdown in older adults is linked to brain-level changes, not sensory deterioration, potentially due to neurotransmission issues and neuron loss.

Step-by-step explanation:

Timothy Salthouse tested both processing speed and memory in adults of various ages. He concluded that the loss of speed occurs at the level of the brain and not in the senses. Physiological changes in neurotransmission and the continuation of the loss of neurons, may be the cause of changes in memory. Researchers like Forstmann and colleagues found that older participants experienced slower processing due to degeneration of corticostriatal connections. Furthermore, factors like memory trace decay, proactive interference, and neuroadaptations are known to affect memory, illustrating the complexity of cognitive changes in old age.
