If there is a .8 correlation between hand size and brain size, then there is a:
- A.
Weak positive correlation
- B.
Strong positive correlation
- C.
Weak negative correlation
- D.
Strong negative correlation
- E.
No correlation
Correct Answer
B. Strong positive correlationExplanation
A strong positive correlation suggests that as hand size increases, brain size also increases. In this scenario, with a correlation coefficient of .8, there is a strong positive relationship between hand size and brain size. This means that individuals with larger hands tend to have larger brains, while those with smaller hands tend to have smaller brains. The correlation coefficient of .8 indicates a strong and almost perfect positive relationship between the two variables.Rate this question:

This man campaigned to make psychology its own separate science and made the first laboratory for psychology research.
- A.
G. Stanely Hall
- B.
B.F. Skinner
- C.
Sigmund Freud
- D.
Wilhelm Wundt
Correct Answer
D. Wilhelm WundtExplanation
Wilhelm Wundt is the correct answer because he is known as the father of experimental psychology. He campaigned to establish psychology as a separate scientific discipline and is credited with opening the first laboratory dedicated to psychological research at the University of Leipzig in Germany in 1879. Wundt's laboratory focused on studying human consciousness and perception, and his work laid the foundation for the development of modern psychology as a scientific field.Rate this question:

Pete Psych examined the effects of room temperature on the effectiveness of studying. He took the first 50 students who came to school and asked them to participate in the experiment. He treated each student equally and told them what was going on. Then, Pete executed the experiment and found that the closer to 71.8 degrees Fahrenheit the room was, the more effective the studying. What was Pete's error?
- A.
Social desirability bias
- B.
Sampling bias
- C.
Placebo effect
- D.
Experimenter bias
- E.
All of the above
Correct Answer
B. Sampling biasExplanation
Pete's error is sampling bias. He only took the first 50 students who came to school, which means his sample was not representative of the entire student population. This could lead to biased results as the sample may not accurately reflect the larger population.Rate this question:

The "All-or-None" law states that:
- A.
Either a neuron fires off, or it doesn't
- B.
All of the Hormones are released into the bloodstream at once
- C.
The Synaptic Cleft absorbs every neurotransmitter or none
- D.
Either all of the neurons in the Central Area are effected or none are
Correct Answer
A. Either a neuron fires off, or it doesn'tExplanation
The "All-or-None" law refers to the principle that a neuron either fires an action potential or it does not. This means that if the neuron reaches its threshold, it will generate an electrical impulse and transmit it down the axon to other neurons, muscles, or glands. However, if the stimulus does not reach the threshold, the neuron will not fire and no action potential will be generated. This law applies to individual neurons and does not apply to the release of hormones, the absorption of neurotransmitters, or the effect on neurons in a specific area.Rate this question:

An Electroencephalography (EEG) studies the brain by:
- A.
Stimulating a portion of the brain with electricity and observing the effects
- B.
Enhancing or suppressing activity in a particular region of the brain
- C.
Monitoring electrical activity in the brain
- D.
Monitoring radioactive chemicals as they flow through the blood into the brain
Correct Answer
C. Monitoring electrical activity in the brainExplanation
An Electroencephalography (EEG) is a technique used to study the brain by monitoring its electrical activity. This involves placing electrodes on the scalp to detect and record the electrical signals produced by the brain. By analyzing these signals, researchers can gain insights into brain function and activity, such as identifying abnormal patterns associated with certain neurological conditions. This method does not involve stimulating the brain with electricity or monitoring radioactive chemicals, but solely focuses on the measurement and analysis of electrical activity in the brain.Rate this question:

The part of the brain that acts as a relay system by monitoring all incoming information and sending it to the correct place
- A.
Thalamus
- B.
Medulla
- C.
Cerebrum
- D.
Pons
Correct Answer
A. ThalamusExplanation
The thalamus is a part of the brain that acts as a relay system by monitoring all incoming information and sending it to the correct place. It receives sensory signals from various parts of the body and relays them to the appropriate areas in the cerebral cortex for further processing. The thalamus plays a crucial role in regulating consciousness, sleep, and alertness. It acts as a filter, allowing only important information to reach the cerebral cortex while filtering out irrelevant or unnecessary stimuli.Rate this question:

Ethnocentrism is:
- A.
Behavior explained in terms of Psychological processes
- B.
The mental process involved in acquiring knowledge
- C.
The Emphasis the unique qualities of humans
- D.
Viewing ones group as superior and as the standard for judging
Correct Answer
D. Viewing ones group as superior and as the standard for judgingExplanation
Ethnocentrism refers to the belief or attitude that one's own ethnic or cultural group is superior to others, and that it should be used as the standard for judging and evaluating other groups. This perspective often leads to a biased and narrow-minded view of other cultures, as it places one's own group at the center and interprets everything based on its own values and norms. Ethnocentrism can hinder intercultural understanding and cooperation, as it fosters prejudice and discrimination against those who are perceived as different or inferior.Rate this question:

The requirements for a control group are:
- A.
Random Sampling
- B.
Random Assignment
- C.
Results must be due to independent variable
- D.
All of the Above
Correct Answer
D. All of the AboveExplanation
The correct answer is "All of the Above" because in order to establish a control group, random sampling and random assignment are necessary to ensure that the group is representative and unbiased. Additionally, the results observed in the control group must be solely attributed to the independent variable being studied, without any external factors influencing the outcome. Therefore, all of these requirements are essential for a control group.Rate this question:

In order to use deception in an experiment, the experimenter must:
- A.
Tell the participants that they will be deceived in some way
- B.
Fully debrief the participant after the experiment is over
- C.
Only deceive when necessary
- D.
Both A and C are correct
- E.
Both B and C are correct
Correct Answer
E. Both B and C are correctExplanation
Deception in an experiment involves intentionally misleading participants. In order to ethically use deception, the experimenter must fully debrief the participant after the experiment is over, explaining the true nature of the study and any deception used. This is important to ensure that participants are not left with any negative psychological effects. Additionally, deception should only be used when necessary, meaning that there should be a valid reason for deceiving participants, such as maintaining the integrity of the study or preventing demand characteristics. Therefore, both options B and C are correct in terms of using deception in an experiment.Rate this question:

Which of the following is not a part of the Peripheral Nervous System?
- A.
Central Nervous System
- B.
Somatic Nervous System
- C.
Autonomic Nervous System
- D.
Sympathetic Nervous System
Correct Answer
A. Central Nervous SystemExplanation
The Central Nervous System is not a part of the Peripheral Nervous System. The Peripheral Nervous System consists of all the nerves and ganglia outside of the brain and spinal cord, while the Central Nervous System includes the brain and spinal cord. The Somatic Nervous System, Autonomic Nervous System, and Sympathetic Nervous System are all components of the Peripheral Nervous System.Rate this question:
