1. Cara has just finished eating a huge piece of sweet chocolate cake. She is then asked to participate in a taste-test to determine whether she can detect small amounts of sugar added to water. She is likely to have:A. a low threshold, and thus a low sensitivityB. a low threshold, and thus a high sensitivityC. a high threshold, and thus a high sensitivityD. a high threshold, and thus a low sensitivity2. Wendy participates in a color perception experiment in which she is presented with a constant green dot on the left side of the screen (wavelength = 530nm) and another dot on the right side of the screen that varies in wavelength across trials (500nm, 510nm, 520nm, 530nm, 540nm, 550nm, 560nm, or 570nm). Her task is to determine if the two dots are the same or different. In this experiment, the green dot on the left side is the ____________ while the dot on the right side is the ____________.A. test stimulus; experimental stimulusB. comparison stimulus; test stimulusC. initial stimulus; comparison stimulusD. standard stimulus; comparison stimulus3.

Which of the following statements about the P pathway is TRUE?A. The ganglion cells involved are quick to respond.B. It relies on input from midget ganglion cells.C. It is involved in the perception of illumination differences.D. It is involved in the perception of rapid movement.5. Which of the patients below most likely has akinetopsia?A. Stephanie cannot kick a moving ball that is rolled toward her.B. Katie is unable to name the individuals in a recent family photo.C. Jenny calls a line-drawing of a ladder “a bookcase”.D. Heather reports that she only sees the world in black and white.6. Cases of blind individuals who have acquired the ability to see later in life indicate that:A. experience plays little role in visual perceptionB. basic visual abilities are able to be acquired but complex visual tasks cannot beC. color perception develops quickly but face perception takes more time to learnD. both A and B7. The visual angle of a person facing you in the distance:A. changes as she moves left or rightB. changes as she moves forward or backwardC. remains constant despite any changes in her positionD. both A and B8. Which of the following statements is FALSE?A. Larger objects are easier to see than smaller objects.B. Objects that are 4 feet away are easier to see than objects that are 40 feet away.C. Objects visible under low contrast conditions are easier to see than objects under high contrast conditions.D. Objects presented at a luminance of 80 cd/m2 are easier to see than objects presented at a luminance of 20 cd/m2.9. When you engage in a real-life task, such as assembling a bicycle, you are likely to move your eyes to:A. guide an object (e.g., a screwdriver) toward another object (e.g., a screw)B. locate an object (e.g., the wheels, a wrench) that is neededC. check on the condition of an object (e.g., are the handlebars on straight?)D. all of the above10. According to the __________________ approach, we store abstract, idealized patterns in memory. (p. 131)A. prototype-matchingB. spatial frequency analysisC. feature-integrationD. computational11. Which of the following statements about face perception is TRUE?A. We are good at recognizing faces when they are blurred but have difficulty identifying inverted faces.B. We are good at identifying inverted faces but have difficulty recognizing faces when they are blurred.C. We are good at recognizing faces when they are blurred as well as when they are inverted.D. We have difficulty recognizing faces when they are blurred as well as when they are inverted.12.
