Sensation

The lowest stimuli intensity required for detection is the ______ and the smallest noticeable difference between a standard stimulus intensity and another stimulus value is the ______.

• absolute threshold; just noticeable difference

• base value; just noticeable difference

• response criterion; sensory constant

• just noticeable difference; absolute threshold

If you move your watchband up your inch or so, you will feel it only for a few moments. This best illustrates:

• parallel processing

• accommodation

• sensory adaptation

• Weber's Law

The process that occurs when special neuron receptor sites in the sense organs are activated, allowing various forms of outside stimuli to become neural signals in the brain.

• sensory adaptation

• transduction

• sensation

• trichromatic theory

Which of the following best describes the concept of 'sensation' in social studies?

• The process of interpreting sensory information

• The initial detection of energy from the physical world

• The emotional response to a stimulus

• The cognitive processing of sensory input

In the context of sensation, what does the term 'absolute threshold' refer to?

• The maximum intensity of a stimulus that can be detected

• The minimum intensity of a stimulus that can be detected

• The average intensity of a stimulus that can be detected

• The intensity of a stimulus that is always detected

What is the 'just noticeable difference' in sensation?

• The smallest change in stimulus intensity that can be detected

• The largest change in stimulus intensity that can be detected

• The average change in stimulus intensity that can be detected

• The change in stimulus intensity that is always detected

Which of the following is an example of sensory adaptation?

• Feeling cold when you first enter a swimming pool

• Hearing a loud noise and immediately covering your ears

• Smelling a strong odor and eventually not noticing it

• Seeing a bright light and squinting your eyes

What role do sensory receptors play in sensation?

• They interpret sensory information

• They detect and respond to stimuli

• They store sensory information

• They transmit sensory information to the brain

How does the concept of 'sensation' differ from 'perception'?

• Sensation involves detecting stimuli, while perception involves interpreting them

• Sensation involves interpreting stimuli, while perception involves detecting them

• Sensation and perception are the same processes

• Sensation involves emotional responses, while perception involves cognitive responses

Which of the following is NOT a characteristic of sensation?

• It is a passive process

• It involves the detection of stimuli

• It requires conscious awareness

• It is the first step in processing sensory information
