A. Sensation is the process of detecting external stimuli and changing those stimuli into nervous system activity. 1. Sense receptors are specialized neural cells that change physical energy into neural impulses.

Which of the following types of disorders is characterized by complaints of bodily symptoms?
Somatic symptom disorder is characterized by an extreme focus on physical symptoms — such as pain or fatigue — that causes major emotional distress and problems functioning.
What are the three psychological dimensions of our visual world?
Let's look at how color vision works and how we perceive three dimensions (height, width, and depth).
How did psychophysics influence the development of psychology?
How did psychophysics influence the development of psychology? Lifting weights, visual brightness and distance, and tactile distance. Psychophysics allowed him to discover the absolute threshold and differential threshold.
Which of the following is technically the stimulus intensity that is detected 50 of the time?
Abstract: Threshold is often defined as that stimulus intensity which is correctly detected 50% of the time.
Can your mind create physical symptoms?
So if you're experiencing unexplained aches and pains, it might be linked to your mental health. According to Carla Manley, PhD, a clinical psychologist and author, people with mental illnesses can experience a range of physical symptoms, such as muscle tension, pain, headaches, insomnia, and feelings of restlessness.
Is when a person has physical symptoms for which there is no physical cause?
Conversion disorder (functional neurological symptom disorer) is a condition in which the symptoms affect a person's perception, sensation or movement with no evidence of a physical cause.
Why do we not experience large black empty regions in our visual field?
The reason we don't experience large black empty regions in our visual field is because of the visual system, it fill it in with infraction from the surrounding area. ... Patients usually first notice problems with the peripheral vision under lowlight conditions.
Is vision physical or mental?
The visual system constructs a mental representation of the world around us ([link]). This contributes to our ability to successfully navigate through physical space and interact with important individuals and objects in our environments.
What involves the conversion of sensory stimulus energy into neural impulses?
The conversion from sensory stimulus energy to action potential is known as transduction.
What is physical stimulus?
2 : an influence that acts usually from outside the body to partly change bodily activity (as by exciting a receptor or sense organ) Light, heat, and sound are common physical stimuli.
What did Wundt's pendulum experiment demonstrate?
What did Wundt's pendulum experiment demonstrate? People need time to shift between two different stimuli. What is the difference between behaviorism and cognitive psychology?
What did Gustav Fechner contribution to psychology?
Gustav Theodor Fechner (b. 1801–d. 1887) is well known to psychologists as the founder of psychophysics, a set of methods for empirically relating measured sensory stimulus to reported sensation.
How much must a strong stimulus change for a person to notice the change according to Weber's law?
The just noticeable difference (JND), also known as the difference threshold, is the minimum level of stimulation that a person can detect 50 percent of the time.
What is meant by bottom up processing?
Bottom-up processing can be defined as sensory analysis that begins at the entry-level—with what our senses can detect. This form of processing begins with sensory data and goes up to the brain's integration of this sensory information.
What is a stimulus below your absolute threshold called?
The stimuli that are not enough to reach de absolute threshold and therefore are below to it are called subliminal stimuli.
