According to intellectual historian Jan E. Goldstein, the initial introduction of idée fixe as a medical term occurred around 1812 in connection with monomania. [1] The French psychiatrist Jean-Étienne Dominique Esquirol considered an idée fixe – in other words an unhealthy fixation on a single object – to be the principal symptom of monomania. [2]
Functional fixedness is a cognitive bias that limits a person to use an object only in the way it is traditionally used. The concept of functional fixedness originated in Gestalt psychology, a movement in psychology that emphasizes holistic processing.
Fixation (German: Fixierung) [1] is a concept (in human psychology) that was originated by Sigmund Freud (1905) to denote the persistence of anachronistic sexual traits. [ 2 ] [ 3 ] The term subsequently came to denote object relationships with attachments to people or things in general persisting from childhood into adult life.
The time interval in between the onset of the cue and the onset of the target is defined as the stimulus onset asynchrony (SOA). Previous studies using this spatial cueing task found that in addition to cue validity, behavioural reactions were also affected by SOA. The effect of the SOA varies depending on whether a central or peripheral cue is ...
Freud saw inhibited development, fixation, and regression as centrally formative elements in the creation of a neurosis.Arguing that "the libidinal function goes through a lengthy development", he assumed that "a development of this kind involves two dangers – first, of inhibition, and secondly, of regression".

Research on the Aha! moment dates back more than 100 years, to the Gestalt psychologists' first experiments on chimpanzee cognition. [9] In his 1921 book, [9] Wolfgang Köhler described the first instance of insightful thinking in animals: One of his chimpanzees, Sultan, was presented with the task of reaching a banana that had been strung up high on the ceiling so that it was impossible to ...
One kind of visual inputs stands out for the primary visual cortex (V1) but not for visual awareness or for other cortical areas, [22] they are distinctive in term of whether the left or right eye receives the inputs, e.g., an apple shown to the left eye among many other apples of the same appearance shown to the right eye.
The explicit task-cuing procedure was developed to investigate the time course of task switching. The interval between the presentation of the cue indicating which task to perform and the presentation of the target stimulus can be manipulated to demonstrate the effect of available processing time on performance.
