Puppy Dog

dogcroppped.jpgOperant conditioning is a type of learning process by which people (or animals!) learn by positive or negative consequences.  For example, if a dog sits when it is commanded to by its owner, and gets a treat, or reward, for performing that behavior (the sitting), the behavior is more likely to happen again. This is because of the pleasant consequences the dog now associates with that behavior. Hence, the behavior became strengthened, and will be more likely to happen again in the future.

Chocolate Bar

Beta-endorphins have the ability to induce a mild euphoric state similar to how one feels when seeing a loved one.

Test Tube

The individuals will then report that the treatment was successful, but then later it is discovered that the “treatment,” was a placebo, an ineffectual treatment.  For example, let’s say Courtney takes part in a psychological study and is told that she is being given an anti-anxiety medication to help her with her social anxiety issues.  She takes the drug and after a few weeks reports that she is experiencing less anxiety.  But Courtney was actually given a placebo (sugar pill) which should have no effect on her anxiety.  The placebo effect is thought to occur because the individual’s belief in the suggested treatment is so strong.

Sand Timer

The female egg, known as an ovum, is the largest cell in the female body, roughly the size of a grain of sand or the diameter of a single hair.  Sperm cells, by comparison, are so small that it would take several thousand of them combined to equal the size of one ovum.  Upon a successful union between the two cells, the egg, which is then considered to be fertilized, will begin to change and grow rapidly.  Within an average time frame of 40 weeks, a healthy fertilized egg will grow a heart, eyes, skin, bones, and all of the other organs necessary to sustain life outside the female’s body. Isn’t it amazing that something that started out so small will, on average, grow into an eight pound, 20 inch long human being
