Psychology. Object permanence is the understanding that whether an object can be sensed has no effect on whether it continues to exist (in the mind). This is a fundamental concept studied in the field of developmental psychology, the subfield of psychology that addresses the development of young children's social and mental capacities.
Attention span. Attention span is the amount of time spent concentrating on a task before becoming distracted. [1] Distractibility occurs when attention is uncontrollably diverted to another activity or sensation. [2] Attention training is said to be part of education, particularly in the way students are trained to remain focused on a topic of ...
Iconic memory is the visual sensory memory register pertaining to the visual domain and a fast-decaying store of visual information. It is a component of the visual memory system which also includes visual short-term memory [1] (VSTM) and long-term memory (LTM). Iconic memory is described as a very brief (<1 second), pre-categorical, high ...
Later research on short-term memory and working memory revealed that memory span is not a constant even when measured in a number of chunks. The number of chunks a human can recall immediately after presentation depends on the category of chunks used (e.g., span is around seven for digits, around six for letters, and around five for words), and even on features of the chunks within a category.
Multi-store model: Atkinson and Shiffrin's (1968) original model of memory, consisting of the sensory register, short-term store, and long-term store. The model of memories is an explanation of how memory processes work. The three-part, multi-store model was first described by Atkinson and Shiffrin in 1968, [1] though the vac idea of distinct ...
Long-term memory (LTM) is the stage of the Atkinson–Shiffrin memory model in which informative knowledge is held indefinitely. It is defined in contrast to sensory memory, the initial stage, and short-term or working memory, the second stage, which persists for about 18 to 30 seconds. LTM is grouped into two categories known as explicit ...
Known for. Research in Cognitive Psychology, Iconic Memory. George Sperling (born 1934) [1] is an American cognitive psychologist, researcher, and educator. Sperling documented the existence of iconic memory (one of the sensory memory subtypes). Through several experiments, he showed support for his hypothesis that human beings store a perfect ...
Endurantism or endurance theory is a philosophical theory of persistence and identity. According to the endurantist view, material objects are persisting three-dimensional individuals wholly present at every moment of their existence, which goes with an A-theory of time. This conception of an individual as always present is opposed to ...
