The information processing theory in psychology describes how we receive, encode, store, and retrieve information. It views the mind as a computer-like system that takes in, processes, and outputs information. The key components of this theory include:
1. Sensory Memory: This is the first stage where information from our senses enters our memory system. It holds a large amount of sensory information for a very short duration (milliseconds to seconds). To identify the components of this stage, you can study the research of George Sperling and his iconic experiment on iconic memory.
2. Attention: This determines what information from sensory memory gets selected and further processed. Attention can selectively focus on certain inputs while ignoring others. To study the components of attention, you can explore the concepts of selective attention, divided attention, and sustained attention.
3. Short-Term Memory (STM): Also known as working memory, this component is responsible for temporarily holding and manipulating information for immediate tasks. STM has limited capacity (usually around 7 ± 2 chunks of information) and a short duration (typically less than a minute). Investigating the work of George Miller and his research on the magical number 7 can help you understand the components of STM.
4. Encoding: This process involves transforming sensory information into a form that can be stored in long-term memory. It includes processes such as rehearsal, elaboration, and organization. To explore the components of encoding, you can study various encoding techniques and strategies, such as mnemonic devices and chunking.
5. Long-Term Memory (LTM): This is the stage where information is stored for a long period, potentially indefinitely. LTM has an almost unlimited capacity and duration. It can be further divided into explicit (declarative) memory (conscious retrieval of facts and events) and implicit (procedural) memory (unconscious retrieval of skills and habits). Investigating the work of researchers like Elizabeth Loftus and her research on false memories can provide insights into the components of LTM.
6. Retrieval: This is the process of accessing and using stored information when needed. It involves searching and pulling information from long-term memory into working memory for utilization. Researching the different retrieval cues, such as context-dependent and state-dependent cues, can help you understand the components of retrieval.
Overall, to identify the components of the information processing theory, it is important to study the works of influential psychologists who have conducted experiments and research in each specific area. By understanding their findings and theories, you can grasp the fundamental components of this theory.
