Overlearning

Last updated

Overlearning refers to practicing newly acquired skills beyond the point of initial mastery. The term is also often used to refer to the pedagogical theory that this form of practice leads to automaticity or other beneficial consequences.

Early studies

Memory researcher Hermann Ebbinghaus performed classical overlearning studies in the late 1890s. [1] He noticed that memory for learned material decreased over time (see also forgetting curve). Ebbinghaus recognized that lists of nonsense syllables became more difficult to recall over time, and some lists required more review time to regain 100% recall. He defined overlearning as the number of repetitions of material after which it can be recalled with 100% accuracy. [1]

Contemporary work

A 1992 meta-analysis suggested that overlearning does significantly affect recall over time. It also concluded that the size of this effect may be moderated by the amount of overlearning, task type, and length of retention. [2] The meta-analysis included 15 studies. These 15 studies tested overlearning effects on physical and cognitive tasks. Both types of task showed an effect of overlearning. The effect size for physical tasks was smaller than the effect size for cognitive tasks. [2] The amount of overlearning affected retention: more overlearning led to more retention on both types of task. [2] The length of the retention interval also affected overlearning, but the effects were different for physical and cognitive tasks. Whereas participants overlearning physical tasks increased in ability during the retention interval, participants who overlearned cognitive tasks decreased in recall ability over time. [2]

Some recent studies explicitly examined the interaction of overlearning with retention interval, and concluded that the effects of overlearning tend to be fairly short-lived. [3] [4] Overlearning may be more useful in instances when learners only need short-term retention of the material. [3]

Overlearning geography facts and word definitions

In one study, researchers examined the effects of overlearning geography facts or word definitions. [3] After one week, overlearners recalled more geography facts and word definitions than non-overlearners, but this improvement gradually disappeared after the study. [3] This research suggests that overlearning may be an inefficient study method for long-term retention of geography facts and word definitions. [3] Overlearning improves short-term retention of material, but learners must also spend more time studying. Over time the improvements created by overlearning fade, and the learner is no better off than someone who did not spend time overlearning the material. [3]

Overlearning mathematics

In another study, researchers compared the effects of overlearning and distributed practice on mathematics knowledge. [4] Distributed practice refers to practice that is spaced over time. In Experiment 1, participants completed 10 math problems either all at once or distributed across two sessions. Participants in the distributed practice condition performed no differently from participants in the single-session condition one week later, but distributed practice participants did perform better than single-session participants four weeks later. In Experiment 2, participants completed either three or nine practice problems in one sitting. When participants were retested one or four weeks later, no differences were found between three-problem and nine-problem participants. Researchers found no effect of overlearning on mathematics retention. [4]

Forgetting loss or modification of information encoded in an individuals memory

Forgetting or disremembering is the apparent loss or modification of information already encoded and stored in an individual's short or long-term memory. It is a spontaneous or gradual process in which old memories are unable to be recalled from memory storage. Problems with remembering, learning and retaining new information are a few of the most common complaints of older adults. Studies show that retention improves with increased rehearsal. This improvement occurs because rehearsal helps to transfer information into long-term memory.

Forgetting curve Decline of memory retention in time

The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time that a person is able to recall it. A typical graph of the forgetting curve purports to show that humans tend to halve their memory of newly learned knowledge in a matter of days or weeks unless they consciously review the learned material.

Spaced repetition An evidence-based learning technique performed with flashcards

Spaced repetition is an evidence-based learning technique that is usually performed with flashcards. Newly introduced and more difficult flashcards are shown more frequently, while older and less difficult flashcards are shown less frequently in order to exploit the psychological spacing effect. The use of spaced repetition has been proven to increase rate of learning.

Cognition Act or process of knowing

Cognition refers to "the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses many aspects of intellectual functions and processes such as: perception, attention, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and "computation", problem solving and decision making, comprehension and production of language. Cognitive processes use existing knowledge and discover new knowledge.

Recall in memory refers to the mental process of retrieval of information from the past. Along with encoding and storage, it is one of the three core processes of memory. There are three main types of recall: free recall, cued recall and serial recall. Psychologists test these forms of recall as a way to study the memory processes of humans and animals. Two main theories of the process of recall are the two-stage theory and the theory of encoding specificity.

The interference theory is a theory regarding human memory. Interference occurs in learning. The notion is that memories encoded in long-term memory (LTM) are forgotten and cannot be retrieved into short-term memory (STM) because either memory interferes, or hampers, the other. There is an immense number of encoded memories within the storage of LTM. The challenge for memory retrieval is recalling the specific memory and working in the temporary workspace provided in STM. Retaining information regarding the relevant time of encoding memories into LTM influences interference strength. There are two types of interference effects: proactive and retroactive interference.

The Decay theory is a theory that proposes that memory fades due to the mere passage of time. Information is therefore less available for later retrieval as time passes and memory, as well as memory strength, wears away. When an individual learns something new, a neurochemical "memory trace" is created. However, over time this trace slowly disintegrates. Actively rehearsing information is believed to be a major factor counteracting this temporal decline. It is widely believed that neurons die off gradually as we age, yet some older memories can be stronger than most recent memories. Thus, decay theory mostly affects the short-term memory system, meaning that older memories are often more resistant to shocks or physical attacks on the brain. It is also thought that the passage of time alone cannot cause forgetting, and that decay theory must also take into account some processes that occur as more time passes.

The spacing effect demonstrates that learning is more effective when study sessions are spaced out. This effect shows that more information is encoded into long-term memory by spaced study sessions, also known as spaced repetition or spaced presentation, than by massed presentation (“cramming”).

Testing effect

The testing effect suggests long-term memory is increased when some of the learning period is devoted to retrieving information from memory. It is different from more general practice effect, defined in the APA Dictionary of Psychology as "any change or improvement that results from practice or repetition of task items or activities."

Serial-position effect Tendency of a person to recall the first and last items in a series best, and the middle items worst

Serial-position effect is the tendency of a person to recall the first and last items in a series best, and the middle items worst. The term was coined by Hermann Ebbinghaus through studies he performed on himself, and refers to the finding that recall accuracy varies as a function of an item's position within a study list. When asked to recall a list of items in any order, people tend to begin recall with the end of the list, recalling those items best. Among earlier list items, the first few items are recalled more frequently than the middle items.

Study skills Approaches applied to learning

Study skills, academic skill, or study strategies are approaches applied to learning. Study skills are an array of skills which tackle the process of organizing and taking in new information, retaining information, or dealing with assessments. They are discrete techniques that can be learned, usually in a short time, and applied to all or most fields of study. More broadly, any skill which boosts a person's ability to study, retain and recall information which assists in and passing exams can be termed a study skill, and this could include time management and motivational techniques.

Memory has the ability to encode, store and recall information. Memories give an organism the capability to learn and adapt from previous experiences as well as build relationships. Encoding allows a perceived item of use or interest to be converted into a construct that can be stored within the brain and recalled later from long-term memory. Working memory stores information for immediate use or manipulation which is aided through hooking onto previously archived items already present in the long-term memory of an individual.

The generation effect is a phenomenon where information is better remembered if it is generated from one's own mind rather than simply read. Researchers have struggled to account for why generated information is better recalled than read information, but no single explanation has been sufficient.

Articulatory suppression is the process of inhibiting memory performance by speaking while being presented with an item to remember. Most research demonstrates articulatory suppression by requiring an individual to repeatedly say an irrelevant speech sound out loud while being presented with a list of words to recall shortly after. The individual experiences four stages when repeating the irrelevant sound: the intention to speak, programming the speech, articulating the sound or word, and receiving auditory feedback.

The expertise reversal effect refers to the reversal of the effectiveness of instructional techniques on learners with differing levels of prior knowledge. The primary recommendation that stems from the expertise reversal effect is that instructional design methods need to be adjusted as learners acquire more knowledge in a specific domain. Expertise is described as "the ability to perform fluently in a specific class of tasks."

In the study of learning and memory, varied practice refers to the use of a training schedule that includes frequent changes of task so that the performer is constantly confronting novel instantiations of the to-be-learned information.

In cognitive psychology, Brown–Peterson task refers to a cognitive exercise purposed for testing the limits of working memory duration. The task is named for two notable experiments published in the 1950s in which it was first documented, the first by John Brown and the second by husband and wife team Lloyd and Margaret Peterson.

Distributed practice is a learning strategy, where practice is broken up into a number of short sessions – over a longer period of time. Humans and animals learn items in a list more effectively when they are studied in several sessions spread out over a long period of time, rather than studied repeatedly in a short period of time, a phenomenon called the spacing effect. The opposite, massed practice, consists of fewer, longer training sessions and is generally a less effective method of learning. For example, when studying for an exam, dispersing your studying more frequently over a larger period of time will result in more effective learning than intense study the night before.

A desirable difficulty is a learning task that requires a considerable but desirable amount of effort, thereby improving long-term performance. It is also described as a learning level achieved through a sequence of learning tasks and feedback that lead to enhanced learning and transfer.

Forward testing effect

The forward testing effect, also known as test potentiated new learning, is a psychological learning theory which suggests that testing old information can improve learning of new information. Unlike traditional learning theories in educational psychology which have established the positive effect testing has when later attempting to retrieve the same information, the forward testing effect instead suggests that the testing experience itself possesses unique benefits which enhance the learning of new information. This memory effect is also distinct from the 'practice effect' which typically refers to an observed improvement which results from repetition and restudy, as the testing itself is considered as the catalyst for improved recall. Instead, this theory suggests that testing serves not only as a tool for assessment but as a learning tool which can aid in memory recall. The forward testing effect indicates that educators should encourage students to study using testing techniques rather than restudying information repeatedly.
