AP PSYCHOLOGY

Detailed explanation-1: -The researchers used a rigorously controlled experiment with a placebo condition to avoid the effect of confounding (extraneous) variables. The study is able to establish a cause-and-effect relationship; however, it is a reductionist approach to understanding memory.

Detailed explanation-2: -Rogers and Kesner (2003) found that scopolamine injected directly into CA3 impaired maze acquisition by means of impaired encoding, whereas injections of physostigmine directly into CA3 impaired acquisition by means of impaired consolidation.

Detailed explanation-3: -Thus, this study shows that the neurotransmitter acetylcholine affects the human behaviour of memory causing an increase in memory functions with higher amounts of Ach compared to lower levels of Ach, which decreases memory functioning.

Detailed explanation-4: -Neurotransmitters are important in boosting and balancing signals in the brain and for keeping the brain functioning. They help manage automatic responses such as breathing and heart rate, but they also have psychological functions such as learning, managing mood, fear, pleasure, and happiness.

Detailed explanation-5: -Neurons communicate with each other through a process called neurotransmission. This is a process of neurons sending and receiving neurotransmitters to one another. It’s what we’re referring to when we talk about brain activity and function. Neurotransmitters are chemicals that are sent through the neurons.
