The Stroop effect refers to an increase in response time observed when the word meaning and the stimulus hue do not match. In an incongruent condition, the word 'green' is presented in the color red, whereas in a congruent condition the word 'red' is presented in the color red. To determine at what level of processing the Stroop effect takes place, we recorded event-related potentials while par...
The Stroop phenomenon is the finding that color naming is inhibited by incongruent color words but word reading not by incongruent colors. When the stimulus onset asynchrony (SOA) is manipulated, maximal inhibition of incongruent words on color naming is obtained when the words are presented within 100 msec of the colors, whereas facilitation of preexposed congruent words is constant. These fin...
The J. D. Cohen, K. Dunbar, and J. L. McClelland (1990) model of Stroop task performance is used to model data from a study by D. H. Spielder, D. A. Balota, and M. E. Faust (1996). The results indicate that the model fails to capture overall differences between word reading and color naming latencies when set size is increased beyond 2 response alternatives. Further empirical evidence is presen...
Attentional biases to threat are considered central to anxiety disorders, however physiological evidence of their nature and time course is lacking. Event-related potentials (ERPs) characterized sensory and cognitive changes while 20 outpatients with panic disorder (PD), 20 with obsessive-compulsive disorder (OCD), and 20 healthy controls (HCs) responded to the color (emotional Stroop task) or ...
In synaesthesia, ordinary stimuli elicit extraordinary experiences. When grapheme-color synaesthetes view black text, each grapheme elicits a photism-a highly specific experience of color. Importantly, some synaesthetes (projectors) report experiencing their photisms in external space, whereas other synaesthetes (associators) report experiencing their photisms "in the mind's eye." We showed tha...
Age differences in Stroop interference: contributions of general slowing and task-specific deficits.
This study examined the contributions of general slowing and task-specific deficits to age-related changes in Stroop interference. Nine hundred thirty-eight participants aged 20 to 89 years completed an abbreviated Stroop color-naming task and a subset of 281 participants also completed card-sorting, simple reaction time, and choice reaction time tasks. Age-related increases in incongruent colo...
It can be difficult to identify those at risk of suicide because suicidal thoughts are often internalized and not shared with others. Yet to prevent suicide attempts it is crucial to identify suicidal thoughts and actions at an early stage. Past studies have suggested that deficits in attentional control are associated with suicide, with the argument that individuals are unable to inhibit negat...
The automaticity of reading is often explored through the Stroop effect, whereby color-naming is affected by color words. Color associates (e.g., "sky") also produce a Stroop effect, suggesting that automatic reading occurs through to the level of semantics, even when reading sub-lexically (e.g., the pseudohomophone "skigh"). However, several previous experiments have confounded congruency with...
