What were the major terms of the Treaty of Versailles? (dont answer)
jeka94
The major points of the Treaty were:
1. Germany would take all blame for starting the war.
2. Germany would pay reparations to the other nations for all the damage that occurred during the war. 
3. Germany was not allowed to have an airforce nor submarines. They were also to cut the army to 100k men. There was also certain stretched of land where they could not operate nor station men. 
4. Germany also lost territories, mainly their colonies. 

The Allies set these terms because:
1. They needed justification for the punishments that they were going to set on Germany.
2. By cutting Germany's military and forcing them to pay, Germany wouldn't have the funds nor the manpower to attempt anything like what had just occurred.
3. By taking territory, Germany would lose it's sphere of influence and other vital trade markets. 
The goal was to cripple Germany. The treaty was successful in that. It also led to extreme bitterness in the German people. This, along with a worldwide depression, allowed for the rise of Hitler and the Nazi regime.

STatiana [176]

Sherif's work on the autokinetic effect primarily demonstrates the power of <u>social roles</u>, and Asch's studies on line judgments demonstrate the power of <u>normative influence</u>.

Sherif's experiment showed group norms are set up through interaction of people and the leveling-off of excessive opinions. The end result is a consensus agreement that tends to be a compromise...even if it is wrong.

Muzafer Sherif performed a conventional look at on conformity in 1935. Sherif put subjects in a dark room and instructed them to look at a pinpoint of mild and say how a long way it moved. Psychologists had formerly discovered a small, unmoving light in a darkish room might appear to be transferring. This changed into categorized the autokinetic effect.

Sherif's work counseled that our information of the arena was encouraged by means of others within the absence of goal cues. Asch suggested that even with the physical cues, our perception of the arena is colored with the aid of others (or as a minimum our verbal behavior concerning the perception of the arena is colored by the group).

Nadusha1986 [10]
<span>The above proclamation is Whole Foods Market's higher purpose statement. The higher purpose statement is not to be confused with the company's motto, which is Whole Foods, Whole People, Whole Planet, but both statements show an emphasis on and commitment to the world as a whole. It is also separate from the supermarket chain's mission statement, which is a pledge to quality.</span>
