Textbook Question
Chapter 16, Problem 6ILQ
Watch this video (http://openstaxcollege.org/l/2point) to see a quick demonstration of two-point discrimination. Touching a specialized caliper to the surface of the skin will measure the distance between two points that are perceived as distinct stimuli versus a single stimulus. The patient keeps their eyes closed while the examiner switches between using both points of the caliper or just one. The patient then must indicate whether one or two stimuli are in contact with the skin. Why is the distance between the caliper points closer on the fingertips as opposed to the palm of the hand? And what do you think the distance would be on the arm, or the shoulder?

Then, analyze the following hypothetical situation: Cassey Madrid is a medical assistant at a medical office. He is testing visual acuity in patients for the first time and feels nervous about it. However, Cassey remembered when he did it in his clinical procedures class, so he takes a deep breath and calls the patient, Mr. Saleto. After identifying the patient and welcoming him in the room, Cassey explains the procedure to Mr. Saleto.
What should be the distance between Mr. Saleto and the Snellen chart?
What instructions can Casey give to Mr. Saleto if he uses glasses?
By using the Snellen chart, is Cassey testing distance or near visual acuity?
What does it mean if the result of the test is 20/60?
What are some nonverbal cues that may indicate that the patient is having difficulty reading the line to which Cassey is pointing?
The receptor cells of the peripheral parts of the analyzers can be classified: by the nature of contact
with the external environment (distant and contact); depending on the nature of the adequate stimulus,
the receptors can be divided into mechano-, chemo-, and photoreceptors.

Why must the subject hold the Snellen acuity card close to his or her eyes to test near vision?

- Tactile acuity refers to the minimum separation required between two objects for the brain to perceive them as two separate points. The Two-Point Discrimination test is one method used to measure tactile acuity. A two-pronged instrument such as a bent paperclip is pressed at various locations on the body. The distance between the two ends is increased gradually until the person feels two distinct points. This distance is then measured. The less the distance that two points can be perceived separately, the higher the tactile acuity of that area. When comparing the tactile acuity of various body parts, what have you concluded about the number of receptors in the palm of your hand relative to the number of receptors on your shoulder? a. The tactile acuity for the palm is higher than for the shoulders. Therefore, more receptors are found on the palm than on the shoulders. b. The tactile acuity for the shoulders is higher than for the palm. Therefore, more receptors are found on the…arrow_forwardWrite M or B after each of the following to indicate if it is a monocular or binocular depth cue.
