Module 1.6a

When she sees a photo of a face, Juana is able to recognize it as the face of her mother. Which of the following explains why?

• Weber's Law

• Bottom-up processing

• Top-down processing

• Signals detection theory

As Jeff reads his psychology textbook, he is able to convert the light waves into signals that his brain can interpret due to

• transduction.

• perception.

• priming.

• sensory adaptation.

Natalia is washing her hands, and she adjusts the faucet handle until the water feels just slightly hotter than it did before. Natalia’s adjustment until she feels the change in temperature is an example of

• a subliminal stimulus.

• an absolute threshold.

• a difference threshold.

• signal detection.

Tyshane went swimming with friends who did not want to get into the pool because the water felt cold. Tyshane jumped in and after a few minutes declared, “It was cold when I first got in, but now it’s fine. Come on in!” Tyshane’s body became accustomed to the water temperature due to

• priming.

• absolute threshold.

• difference threshold.

• sensory adaptation.

What type of data does the graph represent?

• Qualitative data

• Quantitative data

• Median data

• Range data

Which of the following is depicted in the graph?

• Absolute threshold

• Transduction

• Signal detection theory

• Weber’s law

While hiking in the mountains, Sarah is able to smell the faint scent of pine trees in the air. According to the concept of absolute threshold, which of the following is true about Sarah’s ability to detect the scent?

• The scent of the pine trees must be above her absolute threshold to be detected.

• Sarah’s detection of the scent depends on the size of the trees, regardless of the scent’s intensity.

• The scent of the pine trees must be below her absolute threshold for her to detect it.

• The absolute threshold does not apply to smell, only to vision and hearing.

Rachel is adjusting the volume on her car radio. When the volume is low, she can easily tell when she turns it up by just a small amount. However, when the volume is already high, she has to turn it up significantly more to notice a difference. Which of the following psychological principles explains Rachel’s experience?

• Sensory adaptation

• Opponent-process theory

• Weber’s Law

• Bottom-up processing
