A researcher wants to test whether grouping by proximity affects perception. Which design best supports that conclusion?

  1. A

    Change the spacing between dots and allow contrast and other image properties to vary freely.

  2. B

    Change dot spacing while controlling other image properties, then compare the result with a carefully matched control.

  3. C

    Ask participants whether the dots seem organized, without changing the display.

  4. D

    Use only brain imaging and infer the percept from the measured activity.

A team wants to learn both when neural responses differ between organized and unorganized displays and which brain regions respond differently. Which approach best fits these goals?

  1. A

    Use fMRI to determine the precise timing of each neural event, and EEG to identify the exact brain region responsible.

  2. B

    Use EEG or MEG to compare response timing, and fMRI to help identify regions that differ across conditions.

  3. C

    Use fMRI alone to establish that an active brain region is necessary for perception.

  4. D

    Use EEG or MEG to prove that a percept is caused by activity in a single specific cell.

    Finding that a region is active during perception using fMRI alone.

  3. C

    Studying perceptual performance after brain injury.

  4. D

    Measuring reaction time without changing or disrupting any brain process.

A person has marked difficulty recognizing familiar faces but retains many other visual abilities. Which term best describes this pattern?

  1. A

    A general inability to perceive any visual shape.

  2. B

    Difficulty connecting a seen object's form to its meaning in every case.

  3. C

    A selective difficulty recognizing familiar faces.

  4. D

    An inability to detect visual stimuli because of reduced basic vision.

A researcher is assessing whether a person has a visual-recognition impairment and wants to rule out alternative explanations. Which steps are appropriate? Select all that apply.

  1. A

    Compare performance across tasks such as matching, copying, and naming.

  2. B

    Assume a low naming score proves a recognition impairment without testing other abilities.

  3. C

    Assess related abilities such as visual acuity, basic shape perception, language, and semantic knowledge.

  4. D

    Test only one familiar view of an object and infer the person's full recognition profile.

A viewer sees a bright shape and contours in a Kanizsa display even though no corresponding physical borders are present. What does this observation best demonstrate?

  1. A

    A real border is physically present wherever the viewer reports seeing a contour.

  2. B

    The visual system can combine incomplete edge cues into a coherent figure.

  3. C

    The effect proves that one particular brain region is necessary for all figure perception.

  4. D

    The illusion occurs only when local edges are absent from the display.

A study finds that an organized visual display changes participants' judgments and is accompanied by activity in a particular brain region. Explain how researchers could strengthen the claim that a brain process contributes to the perceptual effect, and identify at least one limitation or alternative explanation they should consider.

A researcher wants to test whether proximity helps viewers group dots. Which approach best isolates the effect of proximity on perceptual judgments?

  1. A

    Use brain imaging to locate regions active during perception

  2. B

    Vary dot spacing while holding other image properties constant and measure grouping judgments

  3. C

    Study object recognition after brain injury without changing the visual stimuli

  4. D

    Ask participants to describe their visual experiences without controlling the images

Viewers see a bright triangle in an arrangement of incomplete circles, although no triangle borders are physically drawn. What does this percept most directly demonstrate?

  1. A

    The visual system detects only borders that are physically present

  2. B

    The shape is identified solely by its color

  3. C

    The visual system can organize local cues into a figure with illusory contours

  4. D

    The visual system ignores incomplete shapes

To quantify the Ebbinghaus illusion, in which surrounding circles alter the apparent size of a central circle, which task would be most directly informative?

  1. A

    Measure how participants adjust a comparison circle to match the apparent size of the central circle

  2. B

    Record only whether participants can name the surrounding circles

  3. C

    Measure visual acuity without presenting any surrounding circles

  4. D

    Use reaction time alone to infer the exact size of the central circle

Researchers want to determine when brain responses begin to differ for organized and unorganized displays. Which methods are especially suited to this timing question?

  1. A

    fMRI, because its signal directly follows each underlying neural event

  2. B

    Lesion analysis, because it records moment-to-moment activity

  3. C

    TMS, because it measures electrical activity with high temporal resolution

  4. D

    EEG or MEG, because they track electrical or magnetic activity with high temporal resolution
