Reaction time
- Many scientists consider the best proxy measure of the speed or efficiency of thought processes to be reaction time – the time from the onset of a specific signal to the moment an action is initiated. Indeed, researchers interested in assessing how fast information travels through the nervous system have used reaction time since the mid-1800s.

In 1862, Wilhelm Wundt tried to measure the speed of thought by tracking the discrepancy between the actual and perceived position of a swinging pendulum. By 1879, he had invented the reaction time experiment to measure the speed of perception by presenting participants with a tone or light of a particular color and measuring their latency to ...

To quantify the speed of anything, one needs to identify its beginning and end. For our purposes, a “thought” will be defined as the mental activities engaged from the moment sensory information is received to the moment an action is initiated. This definition necessarily excludes many experiences and processes one might consider to be “thoughts.” ...
Thought is ultimately an internal and very individualized process that’s not readily observable. It relies on interactions across complex networks of neurons distributed throughout the peripheral and central nervous systems. Researchers can use imaging techniques, such as functional magnetic resonance imaging and electroencephalography, to see what...
The time it takes for all thoughts to occur is ultimately shaped by the characteristics of the neurons and the networks involved. Many things influence the speed at which information flows through the system, but three key factors are: 1. Distance – The farther signals need to travel, the longer the reaction time is going to be. Reaction times for ...
It’s amazing to consider that a given thought can be generated and acted on in less than 150 ms. Consider the sprinter at a starting line. The reception and perception of the crack of the starter’s gun, the decision to begin running, issuing of the movement commands, and generating muscle force to start running involves a network that begins in the...
Considering how quickly they do happen, it’s little wonder we often feel our thoughts and actions are nearly instantaneous. But it turns out we’re also poor judges of when our actions actually occur. Although we’re aware of our thoughts and the resulting movements, an interesting dissociation has been observed between the time we think we initiate ...
Apr 6, 2023 · Using a fast code helps speed up thought, but to a large extent the brain—like a telegraph network—really depends on efficient pathways. Impulses from the retinas, for instance, have to travel up the optic nerve to the thalamus, which relays the signals to the visual cortex in the back of the brain.
Sep 17, 2015 · But what about the speed of thought? It's a challenging question that's not easily answerable - but we can give it a shot. To quantify the speed of anything, one needs to identify its beginning and end.
Dec 1, 1994 · Recent evidence suggests that sensory information is processed much faster than was previously thought and that individual neurons need to be active for only twenty to thirty milliseconds to mediate perception.

The speed of thinking is a frequently overlooked aspect of mental life. However, the pace of thought is an essential property of thinking, and its consequences have recently begun to be discovered. In this chapter, we review the psychological consequences of accelerated and decelerated thought pace.
