two factors that can lead to stimulus adaptation?

Stimulus adaptation can be influenced by the intensity of the stimulus and the duration of exposure. A strong or intense stimulus may lead to quicker adaptation as the sensory receptors become less responsive over time. Additionally, prolonged exposure to a constant stimulus can cause sensory fatigue, where the nervous system becomes less reactive, resulting in diminished perception of that stimulus. Both factors contribute to the brain's ability to prioritize new or changing stimuli over constant ones.


The smallest intensity of a stimulus that you can detect 50 percent of the time is?

The smallest intensity of a stimulus that you can detect 50 percent of the time is called the absolute threshold. This threshold varies depending on the sensory system and the specific stimulus being measured.


What is a reduction in sensitivity in the presence of a constant stimulus?

It is known as sensory adaptation. This occurs when our sensory receptors become less responsive to a constant stimulus over time, leading to a reduced perception of the stimulus. Sensory adaptation allows us to focus on new or changing stimuli that may be more relevant for survival.


What is the relationship between sensory adaptation and negative adaptation?

Sensory adaptation refers to the decreased response of sensory receptors to a constant stimulus, leading to reduced perception of that stimulus over time. Negative adaptation, on the other hand, involves a decrease in the overall response of a system to a stimulus due to prolonged exposure. While sensory adaptation is specific to sensory receptors, negative adaptation is a more general phenomenon that can occur across various systems in response to prolonged stimulation.


How is an adaptation different from a response to a stimulus?

Generally speaking, an adaptation is a response to a stimulus just one that develops over long periods of time. Usually a stimulus caused an immediate response such as with blinking or sneezing. Adaptations like polar bears having black skin are, however, in response to a stimulus; environmental conditions.


What is the Point at which a person can detect a stimulus 50 percent of time it is presented?

The point at which a person can detect a stimulus 50% of the time it is presented is known as the absolute threshold. This threshold represents the minimum intensity of a stimulus needed to detect it half of the time. It is often used in psychology to study perception and sensory processing.


What is the difference between adaptation and habituation?

Adaptation is the process by which organisms adjust to their environment over time to increase chances of survival, while habituation is a type of learning where an organism decreases or ceases its response to a repeated stimulus. In adaptation, the organism's physical or behavioral traits change to better fit its environment, while in habituation, the organism becomes less responsive to a stimulus that is no longer perceived as important or relevant.


How does the timing of stimulus presentations affect the strength of the conditioned response?

The timing of stimulus presentations can affect the strength of the conditioned response through processes like temporal contiguity and temporal specificity. Pairing the conditioned stimulus and unconditioned stimulus close together in time (temporal contiguity) tends to result in stronger conditioning. Additionally, presenting the conditioned stimulus just before the unconditioned stimulus (temporal specificity) can enhance the strength of the conditioned response.


How is the brain informed that a receptor is adapting to a stimulus?

When a receptor adapts to a stimulus, it sends progressively reduced signals to the brain. The brain interprets this decrease in signals as adaptation, resulting in reduced sensitivity to that specific stimulus over time.


Can phasic receptors exhibit the property of adaptation?

Yes, phasic receptors can exhibit the property of adaptation, where they become less responsive to a constant stimulus over time. This allows them to signal changes or new stimuli more effectively.


Are these two stimulus pulses different as regards their parameters of intensity and duration?

To determine if the two stimulus pulses differ in intensity and duration, you would need to compare their specific measurements. Intensity refers to the strength or amplitude of the pulses, while duration pertains to the length of time each pulse lasts. If one pulse has a higher amplitude or a longer time span than the other, they would be considered different in those parameters. Without the exact values or descriptions of the pulses, it is impossible to conclude definitively.


What is the term for the length of time that it takes for you to respond to a stimulus?

The term for the length of time it takes for you to respond to a stimulus is called reaction time. It is the time from when a stimulus is presented to when a response is initiated.
