A developmental psychologist studying infants' understanding of object permanence uses a method where infants see an event happe
n as it would normally occur. Then, the event is changed, often in a way that creates a physically impossible event. The result of this is that the infants look longer at the changed event indicating that he or she is surprised by it. Which method is being adopted here? a. Violation of expectations b. Habituation and dishabituation C. Visual preference d. Principle of persistence
The correct answer is letter A. Violation of expectations.
Explanation:
We need to pay close attention to the question, otherwise we might be tempted to choose letter B. What was described does comprise the use of habituation and dishabituation, but the name of the method used is violation of expectations. This method is based on the idea that infants will be surprised when they watch an impossible event take place. Since the event is not what the infant expected, they will show dishabituation - they will look at it for a longer period of time than they would if it were a situation they could predict. An event they have seen multiple times would cause habituation, and the infant would lose interest and look away more quickly.
In June 1863, Confederate general Robert E. Lee and his Army of Northern Virginia invaded the North in hopes of relieving pressure on war-torn Virginia, defeating the Union Army of the Potomac on Northern soil, and striking a decisive blow to Northern morale.
The battle of gettysburg was the turning point in the civil war. The south appeared to be winning the war and the north looked like it was close to surrendering. If the Union had lost, they would have ended their chance at winning the civil war. That could mean that if the battle was different, potentially there could still be slavery today.
