Question 1

In sensory transduction,neural energy is derived from

Accepted Answer

Sensory transduction is the process by which physical energy from the environment (such as light, sound, or touch) is transformed into neural energy that can be processed by the nervous system. Therefore, the correct choice is A - physical sources of energy. Weber's law relates to the ability to perceive differences in stimuli, not to the process of transducing physical energy into neural energy. Stereochemical energy and perceptions are not relevant to the process of sensory transduction.

Question 2

The process of receiving,translating,and transmitting messages from the outside world to the brain is called

Accepted Answer

The process of receiving information from the outside world through our senses is called sensation. This information is then sent to the brain to be processed and interpreted.

Question 3

You are studying in your dorm room,but your neighbor is blasting the television in the adjacent room.When you gently request that your neighbor turn the volume down until you cannot hear it,you are asking your neighbor to find your

Accepted Answer

The absolute threshold refers to the minimum amount of stimulation needed for a person to detect a particular stimulus (in this case, the volume of the television). By asking your neighbor to turn down the volume until you cannot hear it, you are essentially asking them to find your absolute threshold.

Question 4

The color of the white paper and the correction fluid you use to cover up mistakes on the paper are not exactly the same,but they are so close that you cannot see any difference.This is because your _______ abilities are limited.

Accepted Answer

The answer of The color of the white paper and...

Question 5

A brain-injured patient cannot interpret sensory stimuli but can detect the presence of a stimulus.This person has a problem with

Accepted Answer

Perception refers to the process of organizing and interpreting sensory information in order to make sense of it. A brain-injured patient who can detect the presence of a stimulus but cannot interpret it is experiencing a problem with perception, rather than sensation (the initial detection of the stimulus), transduction (the conversion of the stimulus into neural signals), or adaptation (the tendency of sensory systems to become less responsive over time).

Question 6

Where does the process of transduction take place?

Accepted Answer

Transduction refers to the conversion of sensory stimuli into neural signals that can be interpreted by the brain. This process occurs at the receptor cell level, where specialized cells within sensory organs (such as the eyes, ears, skin, and nose) respond to specific types of stimuli and generate electrical signals that are transmitted to the nervous system. The other options (A, B, and D) represent different levels of neural processing that occur after transduction has taken place.

Question 7

The absolute threshold is the smallest magnitude of a stimulus that can be ______ and the difference threshold is the smallest magnitude of s stimulus that can be ______.

Accepted Answer

The answer of The absolute threshold is the smallest magnitude...

Question 8

Sensory information is interpreted through the process of

Accepted Answer

Sensory information is transformed into meaningful experiences through the psychological process of perception. Perception refers to the process by which sensory stimuli are organized, interpreted, and consciously experienced.

Question 9

An architect is designing apartments and wants them to be soundproof.She asks a psychologist what the smallest amount of sound is that can be heard.Her question is most related to

Accepted Answer

The architect's question is related to the absolute threshold, which is the lowest level of a stimulus (in this case, sound) that can be detected by the human senses. By understanding the absolute threshold, the architect can design apartments that block out sound to a degree that is undetectable by the human ear.

Question 10

The process of converting light,sound,and other forms of energy from the world we live in into a form of neural impulses our brain can understand is called

Accepted Answer

The process described can be identified as transduction, which is the conversion of physical stimuli into neural impulses that can be interpreted by the brain. Induction refers to drawing conclusions from specific observations, recovery of function refers to the process of regaining lost physical or cognitive abilities, and circumlocution refers to the use of unnecessarily complicated language to express a simple idea.

Question 11

At the center of every sense organ there are ______ that transduce incoming stimuli.

Accepted Answer

The statement specifically mentions that the transducers are located at the center of sense organs, so the correct answer is B. Nuclei may be present in some sense organs, but they are not the transducers themselves. Pheromones are chemical signals used for communication, not for sensing stimuli. Psychophysicalities are not a known term in relation to sense organs or sensory processing.

Question 12

Regarding stimuli in the outside world,collecting data about that world is the function of ______ and interpreting the data that has been collected is the function of ______.

Accepted Answer

Sensation refers to the process of detecting stimuli in the environment through our sensory organs (such as the eyes or ears), while perception involves interpreting and making sense of those stimuli in our brain. Therefore, collecting data is the function of sensation, and interpreting that data is the function of perception.

Question 13

Sensory systems have specialized neurons that transform physical energy into neural messages.These specialized neurons are called

Accepted Answer

Receptors are specialized neurons responsible for transforming physical energy into neural messages. Interneurons are neurons that transmit messages between neurons, while transducers are devices that convert one form of energy into another. Adaptors are not a type of neuron or device involved in sensory processing.

Question 14

We are aware of our internal and external world because we possess

Accepted Answer

Sense organs are responsible for receiving information from the environment and transmitting it to the brain. This information is then processed and interpreted by the brain, allowing us to be aware of our internal and external world. Preceptor muscles, interocular locution, and sensory deprivation do not play a role in our ability to be aware of our environment.

Question 15

The ______ threshold is the smallest magnitude of a stimulus that can be detected.

Accepted Answer

The absolute threshold is the smallest magnitude of a stimulus that can be detected.

Question 16

The smallest intensity of a stimulus that is detected 50 % of the time is

Accepted Answer

The absolute threshold is the smallest intensity of a stimulus that can be detected 50% of the time. Weber's law states that for a difference to be noticeable, it must be a constant proportion, whereas the difference threshold is the smallest difference between two stimuli that can be detected. The sensory threshold is not a specific psychological term.

Question 17

The main function of sensory receptor cells is to

Accepted Answer

The main function of sensory receptor cells is to receive outside forms of energy and translate them into neural impulses that can be transmitted to the brain for processing and interpretation.

Question 18

With incoming sensory stimuli,not every message will be strong enough to be detected.That is,a message must exceed the _______ in order to be processed.

Accepted Answer

The correct term for the level a message must exceed in order to be processed is the threshold.

Question 19

If a person hears two tones that differ in intensity just barely enough to be detected,the point of detection would be the ________ threshold.

Accepted Answer

The difference threshold, also known as the just noticeable difference, is the smallest difference in stimuli that can be detected by an individual. In this situation, the two tones differ in intensity by just enough to be detected, which aligns with the concept of the difference threshold. The sensory threshold refers to the minimum amount of stimuli required to detect a sensation, absolute threshold refers to the minimum intensity needed to detect a stimulus, and transduction refers to the process of converting a physical stimulus into a neural signal.

Question 20

Your friend asks you to help move some boxes.You look at the boxes and without even trying to move them you say,"These boxes are too heavy." Seeing the boxes as heavy is an example of

Accepted Answer

Seeing the boxes as heavy without physically interacting with them involves interpreting sensory information, which is a process of perception.
