![]() Visual acuity: The ability to see fine details.Fovea: A small indentation at the center of the retina that contains the highest concentration of cones.Cone: A type of photoreceptor that distinguishes colors and detects fine details in well-lit conditions clustered in the fovea.Can these unconscious stimuli impact our. According to Gestalt psychology, this apparent movement happens because our minds fill in missing information. Thus, we might sense this 49 of the time. Rod: A type of photoreceptor that processes black, white, and gray light clustered in the retina’s periphery. By definition, yes, because absolute threshold is 50 of the time.Photoreceptors: Specialized light-sensitive neurons in the retina that convert light into neural impulses includes rods and cones. Sensation is the process by which neural impulses are created by stimulation or sensory neurons that results in awareness of conditions inside or outside our.Retina: The light-sensitive inner surface of the eye containing a vast network of photoreceptors.Sclera: The white part of the eye that provides structural support and contains blood vessels. In doing so, we give meaning to stimuli by using our learning, memory, motivation, emotions, and other psychological processes.Accommodation: The process by which the lens changes shape to focus on near or far objects by adjusting how light hits the retina.Lens: A transparent structure that sits behind the pupil and can adjust its shape to bend light for proper focus (working with the cornea).Constriction decreases the amount of light entering while dilation increases the amount of light entering. It is our five senses: eye, ear, nose, mouth, and skin through which we can perceive the world. The perceiving way of two-person probably can not be the same. It starts when we see any objects in the environment around us. Pupil: A small, adjustable opening that is constricted or dilated by the iris. Perception is the process through which we select, organize, and interpret our sensations in a meaningful way.Iris: A piece of muscle tissue that sits behind the cornea and helps the eye adjust how much light enters.Cornea: The transparent, protective outer layer of the eye that bends light waves to assist in proper focus.Signal-detection theory (SDT): A theory that explains how individuals distinguish between meaningful sensory signals and random noise.Weber’s law: States that the size of the JND is directly proportional to the strength of the original stimulus. Sensory perception is the perception in which an individual or an organism is capable of processing any stimulus in the environment.Just-noticeable difference (JND): The smallest change in stimulation that a person can detect 50% of the time.Absolute threshold: The minimum stimulation required for a particular stimulus to be detected 50% of the time.Receptors: Specialized structures that detect specific types of environmental stimuli and transduce them into neural signals.Transduction: Conversion of one form of energy into another, as when environmental stimuli are transformed into neural signals. ![]() Sensation: The process by which sensory receptors receive information from the environment includes vision, hearing, smell, taste, touch, and the vestibular and kinesthetic senses.
