Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.…
Precise coded signal eventually received by the brain depends on how many neurons fire, which neurons fire, and how rapidly these neurons fire.…
Give an example from personal experience. Describe a situation (1 paragraph) in which observed others’ behaviour or in which you are a key player. What is the behaviour? Did a misunderstanding or conflict arise due to differences in perception or a perceptual error?…
For the second experiment, I filled three bowls with water of varying temperatures. The first bowl was hot water, the second bowl, lukewarm water, and the third bowl was cold water. I then placed one hand in the hot water and one hand in the cold water and left them there for three minutes. Afterwards, I placed both hands in the bowl filled with both hot and cold. Upon doing this, the hand that was in the hot water felt cooler while the hand that was in the cold water felt warmer. It seems that the receptors were still feeling the original temperature of the hot and cold water that my hands had been in previously and had not yet adjusted to the new temperature of the lukewarm…
We judge people differently based on the meaning the ATTRIBUTE to their behavior, mainly, if it was internally of externally caused.…
After reading through the introduction chapter of my psychology book, perception and sensation, I concluded that I was not aware how our perception about things took effect and how we as humans could perceive things and act upon. The first section of the chapter, The Perceptual Process, outlined how the perceptual process works in our brains. When acting towards objects that occur in front of us whether they are small or big, it all begins with the lens of our eye and how a person quickly perceives the object. The principle of representation states that everything a person perceives is based not on direct contact with stimuli but on representations of stimuli that are formed on the receptors and the resulting activity in the person’s nervous…
The paper will discuss sensory perception that asks the question can you really trust your senses and the interpretation of sensory data to give you an accurate view of the world. What are the accuracy and the weaknesses of the human senses as they pertain to thinking in general and to your own thinking in particular?…

How do perceptions and stereotypes affect others’ understandings of ourself? Stereotypes and perspective can affect other’s understanding of ourselves. Whether positively or negatively, what group, religion, or culture we are in can define us. Whether the stereotypes about your group are true or false, they still are a part of who you are, even though it may be completely inaccurate. In the novel, The Outsiders, by S.E. Hinton, there are two separate social groups, the socs’ and the greasers.…

Sensation and perception plays two complimentary but totally different roles in how we interpret the world around us. Sensation is the process by which we sense our environment through touch, smell, sight, taste and smell. This raw information from our sensory organs is then transmitted to the brain where perception is made. Perception is our way of interpreting what these sensations mean and how to make sense of it.…
The purpose of this lab was to determine the participant’s two point threshold for the finger, palm, forearm, and back. The experimenter used a dial caliper as the tool to deliver a stimulus to the participant. The following increments were used when adjusting the caliper on each body part: finger 0.01 inches, palm 0.05 inches, forearm 0.1 inches, back 0.1 inches. To accurately record the threshold for each body part manipulated, the following conversions were used for the dial caliper: 10 on the watch dial = 0.01 inches, 50 on the watch dial = 0.05 inches, 100 on the watch dial = 0.1 inches. The experimenter used the sharper tips on the caliper and when applying pressure onto the skin the experimenter made sure that both tips touched the participant’s skin at the same time and each applied the same amount of pressure. This lab used the method of limits and recorded the two consecutive points in which the participant felt two stimulus points and recorded the first as the threshold. These thresholds were recorded for ascending trials only. Each body part (finger, palm, forearm, back) was manipulated in three trails each. The participant was not to watch the delivery of the caliper tips during these trials. In order to accurately record the thresholds, the participant was to clearly state if each application of pressure yielded the sensation of one or two points on each body…
Derived from the Greek word haptikos which means to touch or grasp, Haptics is another form of nonverbal communication. Touch can be used to communicate affection, familiarity, sympathy and other emotions.…
Tactile illusions are found when the perception of a quality of an object through the sense of touch does not seem to be in agreement with the physical stimulus. They can arise in numerous circumstances and can provide insights into the mechanisms subserving haptic sensations. Many of them can be exploited, or avoided, in order to create efficient haptic display systems or to study the nervous…
