The key question at the heart of the module is that how perception emerges from the sensation as perception is the processing, organization, and interpretation of the sensory organs, which will drive the conscious experiences for the world (Goldstein,2016). On the other hand, a sensation is defined as the feeling which is based on the physical features of the stimulus, by the acquiring of knowledge, expectations and the past experiences.
The most important information in this module is that brain can interpret and communicate by the use of neurons, which later transmit into neurotrans that will provide electric impulses for the brain. This module also provides information for sensory coding by translating the physical properties of stimulus in the neural impulse pattern.
The main inferences in this module are about Psychophysics, and absolute threshold which defined that psychophysics is the subfield of study that will develop in the nineteenth century by the eminent researcher's named Weber and Fechner that will examine the psychological experiences of the stimulus and absolute threshold is the intensity of stimulation that has been occurred prior experiencing the sensation (Hamlyn,2017).
The main assumption(s) underlying the author's thinking is that bottom-up processing is based on the stimulus and the top down processing is based on the expectations (Wixted,2018). In other words, we can say that the intensity of stimuli would detect more than the chance.
The main point(s) of view presented in this module is (are) that transduction arises at the sensory receptors , by the use of specialized cells in each and every organ of the body, and these sensory receptors transmit messages to the thalamus , which then ultimately send projections to the cortical areas.
What consequences are likely to follow if people ignore the author’s thinking?
The author believes in the fact that the brain constructs the stable representations, by producing the experiences from the external environment. He furthers stated that the experiences are the imaginations of the brain that are residing under the skull (Mather,2016). Neurons inside the brain will not directly make experiences with the outside world but they communicate with other neurons of the brain that are inside and outside, and the entire process happens in less than milliseconds. He further stated that if we are aware of the fact that what brain is doing, it would lead to the paralysis due to overloaded information.
