The controlling effects of stimuli are seen in quite diverse situations and in many aspects of behavior. For example, a stimulus presented at one time may control responses emitted immediately or at a later time; two stimuli may control the same behavior; a single stimulus may trigger behavior A at one time and behavior B at another; a stimulus may control behavior only in the presence of ...
If the stimulus does not warrant a strong enough response, it is said to not reach absolute threshold, and the body does not react. However, if the stimulus is strong enough to create an action potential in neurons away from the photoreceptor, the body will integrate the information and react appropriately.
An example of this is when a person steps on a nail: The leg that is stepping on the nail pulls away, while the other leg takes the weight of the whole body. [4] The crossed extensor reflex is contralateral, meaning the reflex occurs on the opposite side of the body from the stimulus.
For example, if one has adapted to something (like an odor or perfume), one can not consciously force themselves to smell that thing. Neural adaptation is tied very closely to stimulus intensity; as the intensity of a light increases, one's senses will adapt more strongly to it. [21] In comparison, habituation can vary depending on the stimulus.
In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time. [1] During this time, the person attempts to detect the appearance of a particular target stimulus. The individual watches for a signal stimulus that may occur at an unknown time. [2]
However, if the person wants to open up, she says, listen with compassion and understanding. Keeping all these reminders and tips in mind is vital for your well-being and other people’s.
The absolute threshold for touch is a bee's wing dropping onto a person's cheek from one centimeter (0.4 inches) away. Different parts of the body are more sensitive to touch, so this varies from one body part to the next (20). As people age, the absolute threshold for touch becomes larger, especially after age 65.
Yet the Labor Department's monthly jobs report Friday indicated hiring remains robust — with payrolls rising by more than half a million in January — leaving investors wondering what the real ...
