PS101 Chapter Notes - Chapter 4: Low Frequency, Middle Ear, Cochlea
Document Summary
Involves absorpion of energy, such as light or sound waves, by sensory organs, such as ears and eyes. Absorb energy from physical simuli in the environment. Sensory receptors detect simulus energies and convert them into neural impulses, which are sent to the brain. Involves organizing and translaing sensory input into something meaningful: such as your best friends face. The level of light intensity at which the gadget clicks on is its threshold. As simulus intensity increases, the subjects probability to responding to the simuli gradually increases. Psychophysics is the study of how physical simuli are translated into psychological experience. Just noiceable diference (jnd: the smallest diference in the amount of simulaion that a speciic sense can detect. Weber"s law: created by ernst weber, states that the size of a just noiceable diference is a constant proporion of the size of the iniial simulus, constant proporion is called weber fracion.
