Perception experiments investigate time, visual perception, personality traits, and extrasensory perception. Researchers change variables to measure their effect on perception. Time perception experiments use a stopwatch and activities to measure how people perceive time. Visual perception experiments explore the relationship between eyes and the brain, while personality perception experiments examine how people judge each other. Extrasensory perception experiments test if people can perceive things beyond the five senses.
There are many different types of perception experiments, including experiments on time perception, visual perception, personality trait perception, and extrasensory perception. Scientists use various methods to investigate these different types of perception. They generally involve changing a small variable and measuring how much it affects people’s perception of that event or person. This allows researchers to understand how human perception works in many different contexts.
Perception experiments related to the perception of time usually aim to see how distorted a person’s internal perception of time might be. These experiments are generally simple to conduct because they only require a stopwatch and a few activities to use as variables. The researchers will normally set the stopwatch to measure a certain amount of time, then have the participants try to determine how much time has elapsed. Several activities can be performed in this time to provide a variable and this can be used to determine how people perceive time. Most people understand that boring activities always seem to last longer than fun ones.
Visual perception experiments are more focused on the relationship between the eyes and the brain. These can involve anything from visual tricks, which make the participant believe they have observed a certain thing when they have not, to the effect that expectation can have on visual perception. For example, a participant may be presented with two lines with arrowheads on them, one with the arrowheads pointing inward and the other with the arrowheads pointing outward. People often assume that one line is longer than the other, even though they are identical. Participants may also be convinced that they saw something because they expected to see it.
How people judge each other is the basis for another group of perception experiments. Researchers often look at things like posture and weight and determine how these affect the observer’s perception of a person. Computer programs are often used in this type of search so that an identical face, with a modified variable, can be used. This field of psychology looks at exactly what people use to make judgments about each other.
Some perception experiments aim to investigate whether people can perceive things to which the five ordinary senses are blind. Generally, these experiments will be conducted on people who claim to have special abilities, such as psychics, but they can also be conducted on ordinary people. In one type of experiment, a special deck of cards with one of five symbols is used. The participant is asked to identify the symbol on the other side of the card to determine if he has extra-sensory abilities.
