|---|---|---|---|---|---|
| show | Is the process by which our sensory organs detect stimuli from the environment and transmit information to the brain for reception.
🗑
|
||||
| show | Are external information in the environment that provokes a physiological or psychological activity or response.
🗑
|
||||
| Sensory receptors | show 🗑
|
||||
| show | process of detecting & responding to incoming sensory information within the sensory organ.
🗑
|
||||
| Receptive fields | show 🗑
|
||||
| show | process where (sensory) receptors change the type of energy detected into electrochemical energy
🗑
|
||||
| show | Process of sending sensory information as neural impulses to relevant areas of the brain via the thalamus.
🗑
|
||||
| Perception | show 🗑
|
||||
| Interpretation | show 🗑
|
||||
| Visual sensory system | show 🗑
|
||||
| show | A transparent, convex-shape (curved outwards) covering which protects the eye and helps to focus light rays onto the retina at the back of the eye.
🗑
|
||||
| pupil | show 🗑
|
||||
| iris | show 🗑
|
||||
| lens | show 🗑
|
||||
| show | These muscles expand and contract, enabling the lens to automatically bulge to focus nearby objects onto the retina and flatten to focus distant objects onto the retina.
🗑
|
||||
| show | Receives and absorbs light and also processes image. the image focussed onto the retina is an inverted (upside down) and reversed (back to front) image of the object being viewed.
🗑
|
||||
| photoreceptors | show 🗑
|
||||
| rods | show 🗑
|
||||
| cones | show 🗑
|
||||
| show | The centre of the eye. This is the most clear vision and highest concentration of cones.
🗑
|
||||
| show | Transmits visual information from the retina to the primary visual cortex. The nerve exists the eye at the back of the retina, the same point where blood vessels enter.
🗑
|
||||
| blindspots | show 🗑
|
||||
| show |
🗑
|
||||
| visual perception principles | show 🗑
|
||||
| show | The ways in which we organise the features of visual scene by grouping them to perceive a whole, complete form.
🗑
|
||||
| show | We close up, fill in, or ignore gaps and see the objects as complete.
🗑
|
||||
| camouflage | show 🗑
|
||||
| figure ground | show 🗑
|
||||
| show | We tend to see stimuli that are similar in size, shape, colour or form as forming a group. when similarity occurs , an object can be emphasized if it is dissimilar to the others.
🗑
|
||||
| proximity | show 🗑
|
||||
| show | Sources of information from the environment or form within our body that help us to perceive how far away objects are and therefore to perceive depth.
🗑
|
||||
| show | The ability to accurately estimate the distance of objects and therefore perceive the world in three dimensions.
🗑
|
||||
| binocular depth cue | show 🗑
|
||||
| show | When our 2 eyes turn inwards, eye our muscles change their tension. The greater the tension the closer the object, the smaller the tension toe further the object.
🗑
|
||||
| show | 2 eyes in different places 6 or 7 cm apart, this causes a very slight difference in the location of the visual images on retinas.
🗑
|
||||
| show | Need only one eye, but work in both eyes.
🗑
|
||||
| show | The shape of our lens changes to focus on near or distance object. Used for objects within 3 meters.
🗑
|
||||
| pictorial depth cue | show 🗑
|
||||
| linear perspective | show 🗑
|
||||
| interposition | show 🗑
|
||||
| texture gradient | show 🗑
|
||||
| show | The object that produces the smallest image on the retina is perceived as being further away.
🗑
|
||||
| show | Objects that are located closer to the horizon are perceived as being more distant than objects located further away from the horizon.
🗑
