Implicit memory

Implicit memory
Evidence and current research[edit] Advanced studies of implicit memory began only a few decades ago. Many of these studies focus on the effect of implicit memory known as priming.[1] Several studies have been performed that confirm the existence of a separate entity which is implicit memory. In one such experiment, participants were asked to listen to several songs and decide if they were familiar with the song or not. Half of the participants were presented with familiar American folk songs and the other half were presented with songs made using the tunes of the same songs from group 1 but mixed with new lyrics. Current research[edit] According to Daniel L. There are usually two approaches to studying implicit memory. Development[edit] Empirical evidence suggests infants are only capable of implicit memory because they are unable to intentionally draw knowledge from pre-existing memories.

Dunning–Kruger effect Cognitive bias in which people with low ability at a task overestimate their ability In the field of psychology, the Dunning–Kruger effect is a cognitive bias in which people with low ability at a task overestimate their ability. It is related to the cognitive bias of illusory superiority and comes from the inability of people to recognize their lack of ability. Without the self-awareness of metacognition, people cannot objectively evaluate their competence or incompetence. As described by social psychologists David Dunning and Justin Kruger, the bias results from an internal illusion in people of low ability and from an external misperception in people of high ability; that is, "the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others".[1] Colloquially, people experiencing this bias are said to be "on Mount Stupid".[2][3] Original study[edit] Later studies[edit] Mathematical critique[edit]

Outline of thought Nature of thought[edit] Thought (or thinking) can be described as all of the following: An activity taking place in a: brain – organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals (only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain). It is the physical structure associated with the mind. mind – abstract entity with the cognitive faculties of consciousness, perception, thinking, judgement, and memory. Having a mind is a characteristic of humans, but which also may apply to other life forms.[1][2] Activities taking place in a mind are called mental processes or cognitive (see automated reasoning, below) – general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Types of thoughts[edit] Types of thought (thinking)[edit] Listed below are types of thought, also known as thinking processes. Animal thought[edit] Thinking

Forer effect A related and more general phenomenon is that of subjective validation.[1] Subjective validation occurs when two unrelated or even random events are perceived to be related because a belief, expectation, or hypothesis demands a relationship. Thus people seek a correspondence between their perception of their personality and the contents of a horoscope. Forer's demonstration[edit] On average, the students rated its accuracy as 4.26 on a scale of 0 (very poor) to 5 (excellent). Only after the ratings were turned in was it revealed that each student had received an identical sketch assembled by Forer from a newsstand astrology book.[2] The sketch contains statements that are vague and general enough to most people. In another study examining the Forer effect, students took the MMPI personality assessment and researchers evaluated their responses. The Forer effect is also known as the "Barnum effect".

Framing effect (psychology) Framing effect is an example of cognitive bias, in which people react to a particular choice in different ways depending on whether it is presented as a loss or as a gain.[1] People tend to avoid risk when a positive frame is presented but seek risks when a negative frame is presented.[2] Gain and loss are defined in the scenario as descriptions of outcomes (e.g. lives lost or saved, disease patients treated and not treated, lives saved and lost during accidents, etc.). Prospect theory shows that a loss is more significant than the equivalent gain,[2] that a sure gain (certainty effect and pseudocertainty effect) is favored over a probabilistic gain,[3] and that a probabilistic loss is preferred to a definite loss.[2] One of the dangers of framing effects is that people are often provided with options within the context of only one of the two frames.[4] Participants were asked to choose between two treatments for 600 people affected by a deadly disease.

List of cognitive biases Systematic patterns of deviation from norm or rationality in judgment Cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment. They are often studied in psychology, sociology and behavioral economics.[1] Although the reality of most of these biases is confirmed by reproducible research,[2][3] there are often controversies about how to classify these biases or how to explain them.[4] Several theoretical causes are known for some cognitive biases, which provides a classification of biases by their common generative mechanism (such as noisy information-processing[5]). Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. There are also controversies over some of these biases as to whether they count as useless or irrational, or whether they result in useful attitudes or behavior.

Cognitivism (psychology) In psychology, cognitivism is a theoretical framework for understanding the mind that gained credence in the 1950s. The movement was a response to behaviorism, which cognitivists said neglected to explain cognition. Cognitive psychology derived its name from the Latin cognoscere, referring to knowing and information, thus cognitive psychology is an information-processing psychology derived in part from earlier traditions of the investigation of thought and problem solving.[1][2] Behaviorists acknowledged the existence of thinking, but identified it as a behavior. Cognitivism has two major components, one methodological, the other theoretical. Cognitivism became the dominant force in psychology in the late-20th century, replacing behaviorism as the most popular paradigm for understanding mental function. The main issues that interest cognitive psychologists are the inner mechanisms of human thought and the processes of knowing. Costall, A. and Still, A. Jump up ^ Mandler, G. (2002).
