Sensation and Perception

What is the process by which sensory receptors detect and encode stimuli from the environment called?

• Perception

• Sensation

• Transduction

• Adaptation

What term describes the minimum level of stimulation required to detect a stimulus 50% of the time?

• Difference threshold

• Absolute threshold

• Signal detection threshold

• Sensory adaptation threshold

The process by which sensory receptors convert physical stimuli into neural signals is called:

• Adaptation

• Habituation

• Transduction

• Perception

Which part of the eye is responsible for converting light into neural signals?

• Cornea

• Lens

• Retina

• Iris

The three tiny bones in the middle ear that transmit sound vibrations are collectively known as:

• Cochlea

• Ossicles

• Semicircular canals

• Tympanic membranes

True or False: The absolute threshold is the smallest difference between two stimuli that a person can detect.

True or False: Rods in the human eye are primarily responsible for detecting color in bright light conditions.

True or False: Sensory adaptation occurs when our sensitivity to a constant stimulus decreases over time.

True or False: The frequency of a sound wave determines its perceived pitch.

Which Gestalt principle explains why we tend to perceive a series of dots arranged in a line as a single continuous line rather than individual dots?
