Final answer:
The hierarchical network model of memory details how memories are arranged in a semantic hierarchy, where ideas are linked. It is assessed through memory experiments and has limitations including dependence on theoretical assumptions and an oversimplification of memory processes.
Step-by-step explanation:
The hierarchical network model of memory suggests that our memories are arranged in a semantic network that reflects a hierarchy of concepts, with related ideas linked together. A seminal assumption in this model is the idea that the stronger the association between concepts, the stronger the link in memory. The collaboration between Anderson & Reder, and the work of Collins & Loftus helps to explain the spreading activation, in which activating a concept partially activates its associations, thus aiding in retrieval.
Assessment of this model involves investigating how the activation of one concept influences the recall of associated concepts. This might be done in memory experiments where recall or recognition tasks are used to see how well participants remember related items.
However, several limitations impact the effectiveness of the hierarchical network model. The model is highly dependent on theoretical assumptions, and it does not fully develop the temporal transitions in memory processing. Furthermore, the model can be criticized for oversimplifying the complexities of memory storage and retrieval which might be influenced by various other cognitive processes.
