What is a lexical decision -making task?

Lexical decision -making task, or LTD, is a type of psychological study in which the individual is asked to determine whether the sensory entry corresponds to the word. Sensory information can be either visual, in the form of images or groups of letters or auditory. The lexical decision -making task is particularly important for psychology known as semantic memory and a lexical approach. The semantic memory refers to the memory of the facts, meanings and concepts that are not specifically associated with a certain historical point in the individual's life memory. Spexical approach specifically refers to the process in which the connection between stimuli and meaning is created, for example, when the sound is identified as a word.

There are many different variables that scientists can turn into a lexical decision -making task in order to allow them to draw conclusions on which conditions affect the lexical approach, how. How common or rare is, for example, a word can have a significant impact on the way, on average, individuals are individualsable to identify the word. Scientists are also trying to get a wide sample of different test entities to participate in the lexical decision -making task. For example, an individual with a strong education is likely to work better than someone with very small education or with limited literacy.

Psychological tests of this kind are usually evaluated based on how long it takes to test income to identify a sound or image as a word or non-word. For this purpose, the tester is generally asked to press the button on the computer or to perform another decisive and quick action. In many cases, the whole task of lexical decision -making is carried out on the keyboard. This eliminates the risk that the direct presence of a researcher could have any effect on the results of a lexical decision -making task.

Repetition and Association of words are two phenomena that have been proven special meaning in Expea riment with a lexical decision -making task. The word identified as a word at one point of the test will generally be recognized as a word faster later in the test. In addition, a word that is closely linked to the previous word will often be recognized faster than the word without previous associations. "Table", for example, is likely to be recognized faster in a lexical decision -making task if it precedes the "chair" than if it were preceded by "Walrus".
