What is the difference between working memory and short term memory?
4 answers
Working memory and short-term memory (STM) are closely related but distinct cognitive functions. Working memory involves the maintenance and manipulation of temporary information for goal-directed behavior, encompassing attention-like control and short-term storage components. STM, on the other hand, refers to the temporary storage of information for immediate tasks, such as repeating nonwords or lists of digits, and is crucial for language processing and vocabulary acquisition. While working memory is associated with more complex cognitive processes like problem-solving and decision-making, STM is primarily involved in immediate recall tasks and language learning. Additionally, working memory is believed to have inelastic capacity limits that impact various activities, while STM limitations are crucial in parsing complexity and language processing. Both types of memory play essential roles in cognition, with working memory being more multifaceted and STM focusing on immediate retention tasks.

While challenges exist in implementing CEFR due to the need for adjustments to local needs and cultural adaptation, integrating CEFR B2 level into Grade 10 aligns with the broader goals of enhancing English language education in Indonesia.
Does short term memory have limited capacity?
4 answers
Yes, short-term memory (STM) does have a limited capacity. This limitation is a well-documented characteristic of STM, distinguishing it from sensory memory (SM), which has a large capacity but decays rapidly, and long-term memory (LTM), which has a large capacity and can retain information for extended periods. The traditional view of STM capacity is often summarized by Miller's magic number, 7 ± 2, indicating the number of items that can typically be held in STM. However, this capacity can vary based on the nature of the information being processed and the individual's cognitive abilities. Research has shown that STM's capacity limitations are not just about the number of items that can be held but also relate to the complexity and type of information. For instance, visual short-term memory (VSTM) has been found to have both an item capacity, around 4 items, and an information capacity, which refers to the amount of detail that can be retained about those items. This capacity limitation is further supported by findings that show distinct brain areas are associated with different types of VSTM, such as spatial versus object VSTM, indicating domain-specific capacity limits. Moreover, the capacity of STM is not static and can be influenced by factors such as attentional allocation and the duration of stimulus presentation. Despite some claims of a high-capacity stage of VSTM, evidence generally supports the view of VSTM as a limited-capacity system. The conceptualization of STM as a capacity-limited system is fundamental to understanding cognitive performance and is supported by a variety of empirical findings across different domains of memory research.
