1. sensorimeter (0-2)-coordination of senses with motor response, sensory curiosity about the world, languages used for demands and catalouging, object permanence
2. preoperational (2-7)- symbolic thinking, use of proper grammar and syntax to express full concepts, imagination and intuitions are strong, but complex abstract thoughts are still difficult, conservation developed-but not yet mastered.
3. concrete operational(7-11): concepts attached to concrete situations, time, space and quantity are understood and can be applied but not as independent thoughts.
4. formal operations (11+): theoritical, hypothetical and counterfactual thinking, abstract logic and reasoning, strategy and planning become possible, concepts learned in one context can be applied to another
Discrimination is a term used in both classical and operant conditioning. It involves the ability to distinguish between one stimulus and similar stimuli. In both cases, it means responding only to certain stimuli, and not responding to those that are similar.
For example, if a bell tone were the conditioned stimulus, discrimination would involve being able to tell the difference between the bell sound and other similar sounds.
In operant conditioning, discrimination refers to responding only to the discriminative stimulus and not to similar stimuli. For example, imagine that you have trained your dog to jump in the air whenever you say the command, "Jump!" In this instance, discrimination refers to your dog's ability to distinguish between the command for jumping and similar commands such as sit, stay, or speak.
Here is how I like to understand this concept: The "I", the nonconforming, the non-socialized person, the one who make dick moves all the time. The "Me", The conforming, socialized person, who tries to not do any dick moves. So in this question, skipping work for a concert, ignoring one's SO, and dressing inappropriately are all dick moves to make, hence "The I". Studying instead of a party is a conforming action to take, and not a dick move, hence "The Me"
