What is a lexical decision test?

The lexical decision task (LDT) is a procedure used in many psychology and psycholinguistics experiments. The basic procedure involves measuring how quickly people classify stimuli as words or nonwords.

What does a lexical decision task involve?

In the lexical decision task, a participant is presented with a single word, usually visually in the center of a computer screen. The participant’s task is to decide, as quickly and as accurately as possible, whether the word is a real word of his or her language.

Why is lexical decision important?

Lexical decision tasks allow the mapping of orthographic processing at two different levels. First, they can be used to compare the sensitivity of visual stimuli with letters and stimuli with graphic images unrelated to written language. Second, they enable a contrast between familiar and non-familiar spelling items.

How long is the lexical decision task demo?

In the original task, there were 48 associated word pairs. The task is to decide if _both the words are real words (e.g., TEA and COFFEE), or not (e.g., TEA and CFREE). The words chosen in this specific task are created with the fantastic English Lexicon Project. The demo takes less than 2 minutes to complete.

What is the purpose of the lexical decision task?

Which is an independent variable in a lexical decision?

The independent variable was whether the first word was related to the second word. There were numerous permutations of the IV, whether the two words were associated, unassociated, a word followed by a nonword, a nonword followed by a word, or two nonwords. The Dependant Variable was the time to respond to the second word.

How is priming used in the lexical decision task?

Lexical decision tasks are often combined with other experimental techniques, such as priming, in which the subject is ‘primed’ with a certain stimulus before the actual lexical decision task has to be performed.
