Sense Perception Introduction

  • Optical Illusions


This was an illusion that I had never seen before and found interesting. Upon first glance, the face on the left looks angry while the face on the right does not. However, by moving away from the image a little bit and squinting, the expressions seem to change.


I also thought this video, that works off of the blindspot we all have in our vision, was very interesting and works very well for me. The video explains what to do, although not how it works.

  • Visual Agnosia Response

The article about visual agnosia was very interesting to read, although I found it very hard to imagine what it would be like to actually experience the condition. In my mind, one can’t really see the details without seeing the whole picture; rather, I don’t even focus on or notice that my computer is black, says “hp”, “Elitebook”, “Le Jardin Academy” “Kailua•Hawaii”, and “Establish 1961”, is a rectangle, and is smooth. I simply see my computer. Of course, I can see the details, if I take the time to, but the object is seen first not as a sum of the ways I perceive it, but as an object that I already know. I tried to imagine what it must be like to not be able to make this connection, but just like trying to imagine what a new color would look like, it is impossible. The closest I can try to imagine is either trying to visualize something based on someone describing it without actually saying what it is, or those puzzles where you try to deduce what something is based only on extreme close up pictures (you can see small details, but not the whole picture).

  • Theories of Reality

I suppose that I most subscribe to the theory of scientific realism. I do agree that everything is just atoms whizzing around and that we perceive these atoms in a certain way. However, I don’t think that the world is a completely independent reality that is very different from the way that we see it. There is obviously a reason that we perceive the arrangement of atoms in the way that we do; just because the base units are too small for us to perceive doesn’t mean that they don’t have a strong connection to what we do perceive. The reason that my room feels the temperature it does is because of the speed of the movement of the atoms in the air; there’s a direct correlation.

  • Influences on Perception

I do believe that beliefs, culture, and mood all do have an effect on the way that we perceive things. While these factors evidently can’t change the objective details of something (that line will be straight whether you’re a Buddhist or a Muslim, Japanese or Mexican, happy or sad), it does affect the larger picture that we perceive. For example, depending on your beliefs and culture, a woman in a burka can mean religious devotion and modesty or it can mean oppression and sexism.  Depending on your mood, a song can be catchy and fun or obnoxious and shallow.

I think that both of these videos bring up an important and relevant point about technology. Though the views they present are not the same, they do connect. One attempts to highlight the potential power of new technology, while the other shows the drawbacks of technology we already have. This leads us to try to deduce what implications this new technology would bring. While current smartphones may separate people in some ways, having this new technology literally at our fingertips would change interaction completely. For example, one of the features would bring up a word web that describes a person just by seeing their face. This could totally change the way that we meet people. Maybe we don’t bother to talk to someone we would have otherwise liked because we saw a word in their web that we had some prejudice against. We don’t ask the same type of questions anymore because we already know the basics about them. First impressions can’t be controlled by the people anymore; I suppose this could be a good or a bad thing in different situations.

  • Gestalt

Gestalt refers to theories and principles of visual perception, and involves people organizes visual elements into a unified whole. An example of this design is the Dodge logo.


It works mainly on the principle of closure and proximity in conjunction with each other. Though the space is not completely enclosed, the eye completes the shape for us, which would not be possible without the proximity of the separate shapes to each other. There is also some continuation that we perceive, especially in the horns, and the way that we can imagine they curve upwards.

  • Sensory Perception Article

I chose this article simply because I had never heard of an auditory processing disorder before. What Debniak said about being able to hear the individual words but being unable to process and make sense of them was somewhat reminiscent of the description of visual agnosia we read about earlier, but simply with a different sense. This disorder further reinforces the idea that when we see or hear something, we aren’t taking in the individual details or words and then making sense of it. We are able to almost bypass that step and simply see or hear the general concept.
