Sensation & Perception - Vision

Which part of the eye plays the greatest role in bending light to focus on the retina?

• aqueous humour.

• vitreous humour.

• cornea.

• lens.

For vision, transduction is the process by which

• photoreceptors change electromagnetic energy into electrochemical energy.

• photoreceptors change electrochemical energy into electromagnetic energy.

• sensory information is sent to the brain via the optic nerve.

• incoming sensory information is given meaning.

The range of wavelengths from 380 to 760 nanometres is known as the

• electrochemical light spectrum.

• invisible light spectrum.

• visible electrochemical spectrum.

• visible light spectrum.

Visual perception is

• the psychological process of detecting and receiving a visual stimulus.

• the physiological process of detecting and receiving a visual stimulus.

• the psychological process of assigning meaning to visual information.

• the physiological process of assigning meaning to the visual information.

Rods are specialised photoreceptors in the retina that

• are necessary for daytime vision.

• are necessary for colour vision.

• are necessary for visual acuity.

• are necessary for vision in dim light.

The photoreceptors in the retina are responsible for the changing of light into

• photopigments.

• visual energy.

• electrochemical energy.

• electromagnetic energy.

Two major processes occurring in the eye are

• selection and perception.

• reception and transduction.

• organisation and interpretation.

• transduction and interpretation.

Luisa woke at night in her darkened bedroom. At first she could not see anything, but after a few minutes, due to the __________ in her eyes, she could see the shape of her dressing gown hanging on the door. When she turned on the light she could see the colour of the dressing gown, due to the action of her ________.

• cones, rods

• rods, cones

• rods, rods

Emma wants to investigate the effect of light on the eye. She dims the light in the room and

watches the reaction of the pupil. She would find that the diameter of the pupil

• dilates.

• remains constant.

• transduces electromagnetic energy into electrochemical energy.

Which of the following sequence of structures correctly describes part of the visual processing system?

• lens--------pupil------retina-----cornea

• cornea--------retina------occipital lobe-----optic nerve

• lens------retina------ optic nerve-----occipital lobe

• cornea------pupil------retina----iris
