The question of "how many models of memory are there in psychology?" doesn't have a single definitive numerical answer, as there are many different models, some encompassing broad theories and others focusing on specific aspects of memory. However, we can discuss one prominent model: the multi-store model.
The provided reference discusses the multi-store model, a structural model of memory. It states that, according to this model, human memory has three different modes:
- Sensory register
- Short-term store
- Long-term store
Each of these stores is accompanied by a separate control process. Therefore, according to the multi-store model, there are three distinct memory stores. However, it is important to acknowledge that the multi-store model is only one model of memory. Many others exist, such as levels of processing model, working memory model and others. Therefore, instead of a specific number, the best answer would be there are multiple memory models.
