I was reading my Psychology textbook just now and caught something very interesting. Decided to share it here....

Illuminating the Structure of the Eye

Do you guys know where is your blind spot? What is a blind spot? Take the test below.

To find your blind spot, close your right eye and look at the haunted house with your left eye. You will see the ghost on the periphery of your vision. Now, while staring at the house, move the page toward you (in this case, you move closer to the screen la....). When the picture is about a foot from your eye, the ghost will disappear. At this moment, the image of the ghost is falling on your blind spot.

But also notice how, when the picture is at that distance, not only does the ghost seem to disappear, but the line seems to run continuously through the area where the ghost used to be. This shows how we automatically compensate for missing information by using nearby material to complete what is unseen. That's the reason you never notice the blind spot. What is missing is replaced by what is seen next to the blind spot.

The full reason involve the optic nerve, ganglion cell, bipolar cell and receptor cells. (Ramachandran, 1995) Quite confusing....

The second one is very interesting...Hahaha

The Function and Meaning of Dreaming

Do dreams represent unconscious wish fulfillment?

Sigmund Freud viewed dreams as a guide to the unconscious (Freud, 1990). In his unconscious wish fulfillment theory, he proposed that dreams represent unconscious wishes that dreamers desire to see fulfilled. However, because these wishes are threatening to the dreamer's conscious awareness, the actual wishes ---- called the latent content of dreams --- are disguised. The true subject and the meaning of a dream, then, may have little to do with its overt story line, which Freud called the manifest content of dreams.

He also suggested that certain common symbols with universal meanings appear in dreams.

Symbol (Manifest Content of dream) --> Interpretation (Latent Content)

Climbing up a stairway, crossing a bridge, riding an elevator, flying in an airplane, walking down a long hallway, entering a room, train travelling through a tunnel --> Sexual intercourse
Apples, peaches, grapefruits --> Breasts
Bullets, fire, snakes, sticks, umbrellas, guns, hoses, knives --> Male sex organs
Ovens, boxes, tunnels, closets, caves, bottles, ships --> Female sex organs

Interesting? Well, it is up to you whether you want to believe anot because many psychologists reject Freud's view.
Next, solve this:

Try to draw four straight lines so that they pass through all nine dots in the grid above --- without lifting your pencil from the grid.
