How can visual illusions help us to understand lower and higher level process in visual perception? A visual illusion may refers to the case where what we perceive differs from what we suppose to be correct. As Nicholas et al. (2001) note that the idea of a visual illusion presupposes that the object or pattern concerned would be different under other conditions. One view of illusions is that they can be used as tools to probe the mechanisms of visual perception‚ because perceptual errors give us

Which of our faculties do you think is more reliable - reason or perception? Give reasons. There are four ways of knowing. Reason is the way we obtain knowledge by means of our justifications and perception is the way we obtain knowledge by means of our experiences. People take different views on which one of our faculties is more reliable between reason and perception. As far as I am concerned‚ I would like to prefer reason tend to be more trustworthy. Two thirds of what we see

Dispersion: The speed of light is slower in various materials than it is in a vacuum or outer space. When the light passes into a material at an angle‚ the light beam is bent or refracted according to Snell’s Law and the index of refraction of the material. But also‚ the speed of light through a material varies slightly with the wavelength or frequency of the light. Thus‚ each wavelength is refracted at a slightly different angle when passing through a material at an angle. This spreading out of

Biology Report About TEM & SEM There are two types of electron microscopes‚ a Transmission electron microscope (TEM) and a scanning electron microscope (SEM)‚ which both work in different .ways‚ at different magnifications/ In a transmission electron microscope‚ the electron beam passes through a very thin prepared sample. The electrons pass through the denser parts of the sample less easily‚ which gives some contrast. The final image produced from a TEM is two-dimensional. The magnification

(You may find it helpful to draw one of the specimens viewed under the microscope.) Dissecting Microscope Organisms or objects at relatively low magnifications. You can only view oranisms that can be seen with the naked eye. It magnifys up to 40 times the size of the specimens serface by passing throught

Transmitters Light emitting diode (LED) in electronics a semiconductor device that emits infrared or visible light when charged with an electric current. Visible LEDs are used in many electronic devices as indicator lamps‚ in automobiles as rear-window and brake lights‚ and on billboards and signs as alphanumeric displays or even full-color posters. Infrared LEDs are employed in autofocus cameras and television remote controls and also as light sources in fiber-optic telecommunication systems.

Gregory proposed that our past experience‚ knowledge‚ expectations and motivations can affect how we interpret the visual information we receive‚ therefore affecting our perception. He suggested that how we see objects is highly brain driven and indirect‚ and the process takes place so fast that we are unaware of the object in ‘normal perception’; Gregory would say that ‘a perceived object is a hypothesis’. Perceptual constancies show how the brain compensates to provide a constant perception of

How was the Microscope Invented? The microscope is a machine used to see tiny‚ small things such as germs and bacteria. These small creatures are not seen by us but can be seen by a microscope. The three subtopics that will be mentioned are: 1) Who invented the microscope? 2) Why was it invented and What are the different types of microscope. The prediction made was that the microscope was a very important part of life in the middle-ages. People had very serious sicknesses at that
