Visual sensory memory is called iconic memory an image stored in it is called an icon (from the Greek word for "image"). #The persistence of memory meaning psychology seriesSo why did you see smooth motion instead of a rapidly presented series of individual pictures? You did so because of your visual sensory memory, which stores images for up to a second. It was actually a series of frames, each containing a picture slightly different from the one before it. ![]() Though some psychologists question the existence of separate information-processing stages for sensory memory, short-term memory, and long-term memory, there is strong evidence in support of them (Cowan, 1988). Figure 7.1.1 summarizes this information-processing model of memory. Forgetting is analogous to the erasing of information on a hard drive. We are also subject to forgetting-the failure to retrieve information from memory. Similarly, we often rely on cues to retrieve memories that have been stored in the brain. ![]() When you strike certain keys, you provide the computer with cues that make it retrieve the information you desire. Retrieval is the recovery of information from memory. In human and animal memory, information is stored in the brain. Computers typically store information on hard drives or CDs. Storage is the retention of information in memory. Similarly, information in your memory is stored in codes that your brain can process. #The persistence of memory meaning psychology codeWhen you strike the keys on a computer keyboard, your actions are translated into a code that the computer understands. Encoding is the conversion of information into a form that can be stored in memory. The handling of information at each memory stage has been compared to information processing by a computer, which involves encoding, storage, and retrieval. Your ability to recall old memories indicates that information also passes from long-term memory into short-term memory. Information transferred from short-term memory into long-term memory can be stored for up to a lifetime. When you attend to information in sensory memory, it is transferred to short-term memory, which stores it for about 20 seconds unless you maintain it through mental rehearsal-as when you repeat a phone number to yourself long enough to dial it. There are three types of sensory memory that have been studied: iconic (visual), haptic (touch), and echoic (auditory). Sensory memories last for a brief period-from less than 1 second to several seconds. ![]() In this stage, sensory information from the world around you is taken in by sensory receptors and processed by the central nervous system. , also known as the sensory register, is the first stage of memory. Their model assumes that memory involves the processing of information in three successive stages:, , and. This predominance is reflected in the most influential model of memory, developed by Richard Shiffrin and Richard Atkinson (1969). ![]() All rights reserved.Question to answer: Information Processing and Memory sensory memory short-term memory long-term memory Sensory memoryĪfter reading the information about encoding and retrieval, what can you do to change the way you study that will be consistent with the points raised in that section of the chapter? Explain.ĭuring the past three decades, memory research has been driven by the "cognitive revolution" in psychology, which views the mind as an information processor. As such, transience is as important as persistence in mnemonic systems.īehavioral flexibility decision-making forgetting generalization machine learning neurogenesis overfitting regularization.Ĭopyright © 2017 Elsevier Inc. Rather, the goal of memory is to optimize decision-making. According to this view, the goal of memory is not the transmission of information through time, per se. Specifically, we argue that transience (1) enhances flexibility, by reducing the influence of outdated information on memory-guided decision-making, and (2) prevents overfitting to specific past events, thereby promoting generalization. We propose that it is the interaction between persistence and transience that allows for intelligent decision-making in dynamic, noisy environments. Here we draw parallels between neurobiological and computational mechanisms underlying transience. However, recent studies have considered the neurobiology of forgetting (transience). The predominant focus in the neurobiological study of memory has been on remembering (persistence). ![]()
