1.What does the feature integration theory seek to explain in terms of object perception?

The perception of separate object features when the brain is damagedThe way different colors combine to form a single color perceptionThe process of combining tactile and visual informationThe method by which individual object features are combined to recognize a complete object

2.Which of the following statements is INCORRECT?

Rods and cones in the retina are responsible for vision in bright and low light conditions, respectively.There are three types of cones, each sensitive to distinct wavelength ranges of light.Cone signals are processed in the retina to form opponent channels such as green-red and blue-yellow.Large retinal cells exist alongside smaller color-opponent cells and respond to luminance differences between their center and surrounding areas.

3.Which statements accurately describe the characteristics of conjunction search?

The distinction between target and distractors relies on a combination of features rather than a single attribute.The duration needed to locate the target increases as the number of distractors grows.The observer appears to examine each item or small cluster one by one in a sequential manner (serial search).All of the above statements are true.

4.Which theory of perceptual processing highlights continuous feedback loops between higher brain areas (such as cognitive centers) and initial sensory processing stages when interpreting visual information from an object?

5.Which of the following statements about neurons in the primary visual cortex (V1) is INCORRECT?

Neurons in V1 become more responsive to a visual stimulus with repeated exposure over time.The localized receptive fields and binocular properties of V1 neurons align closely with the characteristics of perceptual after-effects.Neurons located in area V1 are strong candidates for the neural basis of visual after-effects in humans.Complex images such as trees, houses, and people are initially processed by mechanisms that focus on local physical features without relating to object identity.

6.Which of the following examples does NOT represent a true sensory after-effect?

After touching fine sandpaper, medium sandpaper feels rougher (and the reverse is true)After prolonged exposure to a high-pitched sound, a medium-pitched tone is perceived as higherPlacing your hand under cold or hot running water before checking a baby’s bath temperature causes misjudgment of how warm the water feels to the babyFollowing the consumption of chocolate, orange juice is perceived as more acidic

7.Which of the following statements is INCORRECT?

A channel system can only indicate the preferred orientation of one individual channel.Perceptual data is probably integrated through a mechanism that combines signals from all channels.During synthesis, channel responses are likely weighted based on the magnitude of activity in each channel.The integration process might determine the 'center of gravity' within the activity distribution.

8.Which TWO statements below correctly describe simultaneous contrast illusions? 1. In the simultaneous tilt illusion, vertical lines appear to tilt away from the angle of the surrounding lines. 2. In the luminance contrast illusion, a grey area looks darker when placed next to a dark region compared to when it is next to a light region. 3. A purple area seems closer to blue when surrounded by red, and shifts closer to red when placed against a blue background. 4. Visual illusions occur exclusively with motion stimuli.

9.Which statement is INCORRECT regarding the serial and parallel processing frameworks?

The serial processing framework is now considered insufficient or at least incomplete.The serial model has either been replaced or modified first by the parallel processing approach and more recently by the recurrent processing framework.The parallel processing approach suggests that different features of a stimulus, like its identity and position, are processed simultaneously via separate pathways from early stages onward.The presence of cones and rods in the retina supports the parallel processing model as evidence of multiple mechanisms extracting information sequentially from the retinal image.None of the above statements are false.

10.Which type of sensory receptor is most abundant in the skin?

Receptors for touchThermoreceptors for heatReceptors detecting pressureNociceptors responsible for pain

11.Which category of contrast effects do the tilt illusion, luminance contrast effect, and color illusion belong to?

12.Which type of cells in the retina are most responsive to light?

13.What do difference thresholds refer to in sensory perception?

They represent the point at which a stimulus is initially noticed.They indicate the minimum change in stimulus intensity that can be perceived.They rely on the amount of energy required to activate a sensory receptor.They are quantified using judgmental Normal Differences.

14.Which principle states that the smallest detectable difference in a stimulus is a fixed proportion relative to the original stimulus intensity?

James lawThe all-or-none principleThe law of diminishing returnsWeber’s law

15.How do neural circuits in various sensory systems typically respond to stimuli?

They react to distinct patterns of stimuliThey respond to the entire visual sceneThey mainly detect objects that are not movingThey form exclusively after birth

16.What term describes information that is processed without reaching conscious awareness?

AdaptiveBelow normalPsychophysicalSubliminal

17.Which type of brain cells process incoming sensory data by detecting edges, angles, shading, and motion?

18.Which of the following is NOT considered a monocular cue used for perceiving depth?

19.Hearing aids are ineffective for a person suffering from ______ deafness.

20.How does the iris and pupil respond in bright lighting to regulate the light entering the eye?

The iris enlarges while the pupil shrinksThe iris tightens and the pupil widensThe iris adjusts focus and the pupil narrowsThe iris contracts and the pupil adjusts focus
