Final answer:
The spreading activation model states that concepts are equal in the strength of their connections, allowing for the activation and retrieval of related concepts regardless of personal experiences or memory organization.
Step-by-step explanation:
The accurate statement regarding the spreading activation model is that concepts are equal in the strength of their connections. According to the spreading activation model, when one concept is activated, it causes other related concepts to be partially activated as well. This means that all concepts have equal potential to be activated and retrieved from memory, regardless of personal experiences or the specific organization of an individual's memory.
