Sensations are what we see, hear, touch, and taste. The major sensations that we use the most is the ability to see and hear. We use sight to what is ahead of use when we are walking, running, and even driving. Being able to hear lets us communicate with each other and lets us know when something is approaching or going on around us when we can't not see it. We use the sensation of touch to feel the world around us. It lets us feel pain when we hit or bump into something. Blind people need to rely on there hearing and sense of touch, because not all objects make sound.
Perception is what we see in terms how far away someone is, how deep a hole is, and when we look at things that it is what we think it is. What I mean by what you think it as is that the brain's perception on an object may be off by how far away something is or the depth of it. The brain will try to complete the object or try to make sense of what is being seen when the object is in pieces and scattered or the picture is being blurred.
One thing I learned is that when the mind sees a two-dimensional objects it tries to put them together to make a three-dimensional object. This is interesting because when we see we see in what is considered 3d. This is due to the fact that each eye sees the same thing from different angles and when both eyes open and the image is combined it causes a 3d effect. I saw this demonstration on a show that was talking about a new 3d camera that is trying to create movies where the viewers don't need 3d glasses. They used a pencil and to hold the pencil at arms length away from you and to close each eye, one at time, and look at it. What you see both times is combined to make what you see with both eyes. This information only changes the way I think about things by having this new information in my mind and realize when I watch 3d movies how the idea came to be.
The article I found was "Psychology of Magic: 3 Critical Techniques." What it is about is that psychologists are trying to find new was of understanding the human mind. They found that magicians have been using mind-bending effects, manipulating people's expectations, and misdirecting their attention, and influence their decision-making. This all intrigues psychologists. The three techniques are psychological misdirection, cognitive illusions, and mental forcing. Psychological misdirection is when the magician points to an object to divert your attention there so that a trick may work. Cognitive illusions rely on manipulating the attention also. Mental forcing like used in card tricks make it inevitable to escape.

Psych. Blog 6#
From interviewing my step-grandmother I learned that times have really changed. We now have more things that we have and want. Which is a good thing because they can help with homework or communication, but also a bad thing for it makes us spoiled. One thing I wish still holds true now to as it did then is how they hang out with friends. They went to movies or to restaurants sure, but they also went for walks or bike rides more often. They were always outside. You don't see that much anymore with all the video games and television shows. I could see myself living back then. I would spend more time with friends and wouldn't have to worry about gangs or drugs. That wasn't around in her day, it makes life seem so much more simpler.
With the parenting adolescence I learned that it's highly normal for teens to become distant from their parents. My mother always made it seem like I was dissing her in some way by not talking to her as much any more. It's also good to know that it's normal to argue with your parents. I was told to never talk back to your parents. If I did it made me seem like the worst child ever, yet my siblings do it all the time now that they became teens. There's not that big of an age difference either, so I really don't get that. Do parents use different parenting styles on different siblings?
One thing I learned in chapter four that in an abusive type of relationship that women are just as likely to throw things or hit their partners as much as men. I'm not going to lie, some of my family and others I know were in abusive relationships. 95% of the time it was the guy being abusive. I know this because I witnessed some of the events, so this information actually surprises me.
Dealing with chapter five, and the videos that go along with it, I learned that babies are legally blind. Due to the cones in the back of the cornea babies are legally blind. Their eye sight is really bad that it takes a month just to see the outline of a face up close, and two months to actually start to take in facial features. Colors don't even develop until at least three months. It's unbelievable the amount of time it takes to see and learn. There was an example in one of the videos where there was this two year-old and this little replica of the room next door. There was a miniture Snoopy and toy Snoopy, and where ever the miniture Snoopy was placed in the replica room the bigger Snoopy was place in the same spot in the actual room. The lady giving the test kept reminding that big Snoopy was in the same spot as minature Snoopy. It took the two year-old looked three times for the Snoopy before she found it. The test was then done on a three year-old. The three year-old found it right away. Thats a whole year difference in age. What they got from this is that every young children think more than we do. I would have never thought that.

Psych. Blog #5
The first thing I learned in the chapter Nature, Nurture, and Human Diversity is that fraternal twins share no more dna than the average siblings. At first I thought they would share more genetics like identical twins. Seeing that they were created around the same time, but that's not the case. The reason I thought this at first was that I assumed fraternal twins came from the same egg like identical twins but they don't.
Another thing I learned was that british want more personal space. I know it's a weird thing to learn, but I always thought that most europeans, including the British, were some what in your face type of people when it comes to talking. The reason behind this is that I've heard people say that when they went to Europe the people get more into your personal space than the do here in the United States.
A third thing that I have learned is that even though women have double the vulnerability to depression and anxiety, men are four times more likely to commit suicide or have a greater alcohol dependency. You'd think since women are more prone to depression their rate of suicide would be larger than that of a male. Also on the debate on men versus women, men are more for a war than women. Explains why most of the more famous or bloody wars had men rulers. Not to discriminate against men or anything, I'm just stating my opinion.
