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.

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.
Threshold stimulus is defined as the?
Threshold stimulus is defined as the minimum level of stimulus intensity that is required to trigger a response in a neuron or muscle fiber. This level must be reached for action potentials to be generated, leading to muscle contraction or nerve signal transmission. If the stimulus is below this threshold, no response occurs, highlighting the all-or-nothing principle of action potentials.
What does limen mean in psychology?
In psychology, "limen" refers to the threshold or point at which a stimulus becomes perceptible to an individual. It is often used in the context of sensory perception, where the limen determines the minimum intensity of a stimulus required for it to be noticed, known as the "absolute threshold." Additionally, it can refer to the difference threshold, which is the minimum change in stimulus intensity needed for a person to detect a difference. Overall, limen is crucial for understanding how we perceive and respond to various stimuli in our environment.

What is the relationship between a stimulus and a reponse?
The stimulus is your bodies reaction to something, say you burnt your hand, this is the stimulus. The reaction is your bodies response to it. In this sense the stimulus will be sensed by sensory neurones which pass an electrical impulse through relay neurons until the impulse gets to the Central Nervous System. This then, gives out another impulse which travels down a Motor Neuron to the muscle telling your hand to be removed from the surface.....
What are the four characteristics of a stimulus in stimulus coding?
The characteristics are modality (type of stimulus), intensity (strength of stimulus), duration (length of stimulus), and location (where the stimulus occurred).
What is a pain threshold?
A pain threshold is the point at which a person starts to feel discomfort or pain from a stimulus. It is the level of intensity at which a person perceives a sensation as painful. Different individuals have different pain thresholds.
What cannot be used for signaling the intensity of a stimulus?
Color perception cannot be used for signaling the intensity of a stimulus, as it is primarily used for distinguishing different wavelengths of light. Other sensory modalities such as touch, taste, and smell are better suited for detecting and signaling the intensity of a stimulus.
Does the duration of the latent period change with different stimulus voltage?
No sorry :(
What is meant by coding of stimulus intensity?
Threshold
How does the brain perceive the intensity of a stimulus?
There are a number of different ways that the brain perceives stimuli. If a person is hurt, the brain sends a reaction to the body. If something good happens, the brain sends good reactions to the body.
What does stimulus intensity mean?
Stimulus intensity refers to the strength or magnitude of a stimulus that is perceived by an individual. It can apply to various types of stimuli, such as light, sound, or touch, and influences how the stimulus is experienced. Higher intensity usually leads to a stronger perception or reaction, while lower intensity may be less noticeable. This concept is important in fields such as psychology and sensory perception, as it helps to explain how organisms respond to their environment.
What principle states that the properties of the action potential are independent of the relative strength of the depolarizing stimulus?
The all-or-none principle states that the properties of an action potential, such as amplitude and duration, are independent of the intensity of the stimulus that triggers it. This means that once a threshold stimulus is reached, the action potential will fire at maximal strength regardless of the strength of the initial stimulus.
What is the type of feedback where the net effect is that the output of the system shuts off the original stimulus or reduces its intensity?
In a negative feedback loop, the output of the system decreases the intensity of the stimulus.
What is law of law of intensity?
The law of intensity, often related to the field of psychology and sensory perception, states that the perceived intensity of a stimulus is proportional to the logarithm of the actual intensity of the stimulus. This principle is commonly associated with Weber-Fechner law, which describes how humans perceive changes in stimuli; as the intensity of a stimulus increases, larger changes are required for perception differences. Essentially, it highlights that our sensory experiences do not scale linearly with physical intensity, but rather logarithmically.
Receptors provide information about the intensity of a stimulus through?
Receptors provide information about the intensity of a stimulus through the frequency of action potentials they generate. Higher intensity stimuli result in higher frequency of action potentials being sent to the brain, signaling a stronger stimulus. This frequency coding allows the brain to interpret the intensity of stimuli.
