Computers are a necessity when it comes to doing work in college and so it is recommended to purchase one. For a student, in my opinion, a laptop is the best option as it can be easily transported. And so here are a few things one should consider when purchasing a laptop:
1. Price- the chosen laptop will need to be affordable, try and get a
reasonably priced one that has all the features you need.
2. Memory- good memory storage is extremely important when considering your future
laptop. You will need to take into account how much memory space you
require for your tasks.
3. Processor- a good processor means a faster computer so this should be an essential
factor to consider.
4. Battery life- look for a laptop that has a long battery life, it is very
irritating if one's laptop dies when unplugged for just a short
period of time.
5. Wireless connectivity- this is unquestionably more convenient, having wires
extending from your laptop when online is a nuisance and
it doesn't give you much freedom with transport.

Uncertain
Not sure if my post about technology, and future post about buying a pc, is included in the "5 posts minimum", so I said I'd throw this in for good measure! By the by, I am delerious with exhaustion and have to stay in college til 3 today... Don't ya just love days like that? :-(
Interesting Technology:
I have chosen to write about functional magnetic resonance imaging (fMRI) as I find this technological advancement very interesting. The following is a brief summary of two articles I have read on the topic.
The first article relates to the use of fMRI to predict what someone is looking at. As fMRI detects blood flow in the brain, it can pinpoint the parts involved in cognitive tasks. Using this technology, scientists gathered information about the processing of images in the brain by recording activity in the visual cortex whilst showing participants randomly selected pictures. This information was compiled to develop a computer model that would predict the pattern of brain activity triggered by any image. This computer model was able to correctly predict which picture, out of 1,000 possibilities, a person was shown with 80% accuracy. These technological advances open up a wide range of possibilities for neuroscientific discoveries.
The second article deals with the use of fMRI in lie detection. As it is widely known, polygraph tests are a highly unreliable indicator of deception. However, fMRI may be the answer. It has been discovered, using fMRI, that when lying different parts of the brain are activated than when telling the truth. Though there are some complications with this method, for example deciphering if someone is actually lying or just resisting the temptation to lie, it shows great promise for the future.

Supposed to be links to sites useful in psychology:

Could I possibly get this CA done in time?
There may be hope for me yet :-) Have finally figured out how to find things on blogspot, as for adding videos and pics that's another matter.... It's going to be a long night... Thank god for nicotine, caffeine, and a housemate who's keeping me from cracking up :-)
Sanity
I HATE COMPUTERS!!!! Trying to at least post something for this CA. Can't figure out how to do anything on this stupid blog and it is literally driving me insane!! Well there's 1 post for ya, guess I've another 4 to follow.... Oh the joys of it all.....
