Answer:
Semantic network.
Explanation:
The activation occuring in Tim's long-term memory conforms to the semantic network model. This model represents every semantic relation (knowledge that binds and represent concepts) in the mind in a network. For example the blue car: in Tim's mind, that blue car represnets the police car. That way, the activation of his long-term memory finds, in the semantic network, the representation of that, which is the blue car.
