According to Weber's law, Dl,S=K, b. The greater the intensity of a stimulus, the harder it is to notice changes in its intensity. To the right is a figure showing magnitude estimations for electric shock, apparent length, and brightness. Which of the statement about the figure is true? d. As electric shock magnitude increases, changes in its intensity feel greater. Farsightedness, or hyperopia, occurs because: D. The cornea doesn't bent light enough or the eyeball is too short Where is the blindspot located? B. On the side of each retina toward the nose. Rods and three types of cones are sensitive to different wavelengths of light because: A) The contain different kinds of opsin Submarine control rooms use only red light because: C) Red light does not bleach Rods The difficulty of reading under dim light conditions can be explained by
B) The fact that rod functioning predominates during dark adaptation. Errors of habituation D) occur when using the Method of Limits and bias you keep making the same response. Suppose that you are looking straight ahead and that an object is present in your left visual field. This object will make an image on the______ side of your retinas and the information will be sent to the _____ side of visual cortex. A) Right, right The ______ problem shows the numerous 3-d objects in the world can create exactly the same 2-d image on the retina B) Inverse projection View point invariance means C) Humans can easily recognize objects when seen from different viewpoints. The ____ problem shows that numerous 3-d objects in the world can create exactly the same 2-d image on the retina B)inverse projection Which of the following best explains why we are more sensitive to horizontal and vertical lines than diagonal lines, also called the oblique effect? B) Selective Rearing Which of the following is NOT true about figure-ground segregation: D) Elements that are vertical are often seen as figures. Which is the following is true about the method of constant stimuli?
C) Lateral Inhibition and figure-ground segregation _______ bipolar cells are found in the periphery of the retina. They have ______ receptive fields which leads them to _____ acuity. C) Diffuse; large; low Sensation Bottom up processing and processes proximal information such as hearing a sound in the ear membrane. It includes vibrations, light for visual. Perception Perception is proximal information and existing knowledge. It's perceiving a distal object such as a tree and going through the perceptual process. Exam 2- You watch Dr. Miles walk across the classroom. According to Gibson's ecological approach, I seem... C) to be moving because of a local disturbance in the global optic array. According to optic flow, if all visual information is shrinking toward the center, what is likely occuring B) You are moving backward According to Corollary Discharge Theory, movement is perceived when C) The comparator receives the corollary discharge signal alone or image displacement signal alone. One benefit of perceiving motion is that it helps us identify objects- that is most related to which Gestalt Grouping Principle? B) Common Fate Motion aftereffects are most related to which of the following:
B) Selective Adaptation Which of the following is NOT TRUE about motion sensitive neurons in the medial temporal lobe? D) Neurons here are most sensitive to movement that is incoherent. Which of the following is required for apparent motion in a single stationary object to occur B) An image must contain big changes in contrast (Dark and light areas) Perceived motion on television is an example of D) Illusory Motion You are sitting on a bench at the Japanese Garden on campus watching the fish in the pond. An especially big fish surfaces and starts swimming around- it looks really cool so you following it with your eyes as it moves around the pond. According to corollary discharge theory, what is happening in regard to your perception of the fish? B) There is a CDS but no IDS, so you see the fish as moving around How do you solve the aperture problem in relation to a moving object? A) By examining the movement of the edges of an object Which of the below doesn't directly provide support for the "opponent-process theory" of color vision? D) Color constancy Which of the following would NOT be true of monochromats B) They are less sensitive to light than trichromats The difference between red and pink is related to D) Saturation (whiteness)
According to the ratio principle A) Lightness constancy will occur as long as the ratio of light reflected from a white surface and a black surface remain constant. Simultaneous color contrast is one of the phenomena that can be explained with Opponent Process Theory and is most related to which of the following things that we have talked about in class: A) Lateral Inhibition What depth cue could be classified as both a monocular cue and oculomotor cue? A) Accomodation Which of the following statements about retinal disparity is TRUE The location of the horopter changes depending on what you are looking at When a person scans a visual scene, he/she usually makes about ___ fixation(s) per second B) Three Egly et. al. (1994) showed that precueing increases the efficiency of information processing B) When the cue appears in the same rectangle as the target stimulus. Which of the following is true about attention in the flicker task? C) Change blindness is more likely if you cannot notice the movement associated with the change. Christine is walking in a mall and thinks she sees a man wearing a red dress. She takes a longer look, and realizes she has seen a man in a suit walking next to woman in a red dress, This is a natural example of B) Illusory conjunctions
You are trying to watch a movie in the movie theater but notice that there is a big spider on the corner of the screen. Although you want to focus on the move, you can't help looking the spider. In this case, A) Looking at the movie involves endogenous attention and looking at the spider involves exogenous attention For every increase of 10 db, sound gets.. B)Twice as loud How many times greater the sound amplitude, or pressure is a 120 db gunshot than our thresold? (Hint: The formula for transforming sound amplitude to decibels is DB=20 log (p/po). You don't need to use the formula for this problem, but it may help you remember how to figure out the answer.. C) 1,000,000 times greater The ends of hair cells in the Organ of Corti bend because of movement of the A) Basilar membrane What is the third harmonic of a note that is 2 octaces above a note with a fundamental frequency of 200? A) 2400 The cochlear implant makes use of B) the tonotopic map of frequencies on the basilar membrane Which of the following ideas best explain why amplitude is measured in decibels? D) Decibels take into account that as amplitude increases, you need a bigger change to notice a change.
C) 20 and 20, The outer hair cells respond to sound by slightly tilting and changing length. Because of the consequence of this, the action fo the outer hair cels is called the B) cochlear amplifier Which sound is the loudest? A) A 1000 hz tone at 40Db The basilar membrane is referred to as the "acoustic prism" because: B) It separates out the frequencies in a complex wave. Which of the following statements about phase locking of hair cells is NOT true? D) Inner hair cells determine frequency based on where they are on the basilar membrane, but outer hair cells rely on phase locking Similarity of timbre and pitch as auditory grouping principle is used to provide B) Auditory Stream Segregation Which of the following statements about sound is TRUE: A) Most sounds in rooms is indirect The precedence effect occurs when A) The listener perceives the fused sound from two speakers to be originating from the lead speaker.
