Sensory memory is the initial stage of memory that holds sensory information for a very brief period. Echoic memory refers to the brief sensory memory of auditory stimuli, which lasts for a few seconds. Eidetic memory, often associated with iconic memory in this context, refers to the ability to recall images with high precision after only a brief exposure, representing the visual sensory system.

Interference can disrupt memory at various stages. It can prevent the initial encoding of new information, disrupt the stability of information in storage, or block the successful retrieval of stored memories. Because interference creates competition between similar memory traces, it can manifest as a failure at any point in the information processing cycle.

Mnemonic devices are structured techniques designed to improve memory retention and retrieval. By utilizing methods like the method of loci (associating items with physical locations), acronyms, or peg-word systems, individuals create meaningful associations that make information easier to store and recall later. These tools serve as cognitive scaffolds that bridge the gap between new information and existing knowledge structures, thereby enhancing overall memory performance.

Encoding is the process by which external stimuli are transformed into a mental representation. This involves active attention, identification, and the initial processing required to move information from sensory input into a form that can be stored in the brain's memory systems.

The tip-of-the-tongue (TOT) phenomenon is a common memory failure where an individual feels certain they know a word but cannot immediately retrieve it from long-term memory. This experience is often characterized by the partial retrieval of information, such as knowing the first letter or the number of syllables, but failing to access the full phonological representation. It highlights the complexity of memory retrieval processes and the distinction between availability and accessibility of information.

The dual-coding theory, often associated with Allan Paivio, proposes that humans process information through two distinct but interconnected systems: one for verbal information and one for visual imagery. By encoding information in both formats, individuals can improve their memory retention, as the two codes provide multiple pathways for retrieval from long-term memory storage.

Retrieval failure occurs when information is stored in long-term memory but cannot be accessed or brought back into conscious awareness. This is often described as the 'tip-of-the-tongue' phenomenon, where the memory trace exists but the cues required to trigger its recall are insufficient or absent at the moment of attempted retrieval.

Recall is a method of memory retrieval that requires an individual to access information from long-term memory without the presence of external cues. Unlike recognition, which involves identifying previously learned information among distractors, recall requires the active reconstruction of the material, often resulting in verbatim or near-verbatim reproduction of the original content.

Interference theory suggests that memory retrieval is hindered when information is similar. Proactive and retroactive interference are most pronounced when the competing information shares common features, making it difficult for the brain to distinguish between the target memory and the interfering material, thereby increasing the likelihood of retrieval errors.

Donald Broadbent proposed the Filter Model of attention in 1958. This theory suggests that information is selected based on physical characteristics, acting as a bottleneck that prevents sensory overload by filtering out irrelevant stimuli before they are processed for meaning.
