- A.
Scientific study of the mind
- B.
Empirical study of conscious and unconscious forces
- C.
Study of mind and behavior
- D.
Scientific study of behavior and mental processes
Correct Answer
D. Scientific study of behavior and mental processesExplanation
Psychology is the scientific study of behavior and mental processes. This means that psychologists use scientific methods to observe, measure, and explain both observable behaviors and internal mental processes such as thoughts, emotions, and perceptions. By studying behavior and mental processes, psychologists aim to understand how individuals and groups function, develop, and interact with their environment. This definition highlights the empirical and scientific nature of psychology, emphasizing the importance of evidence-based research and objective observation in understanding human behavior and cognition.Rate this question:

Only the experiment allows researchers to determine _______.
- A.
Relationships
- B.
Correlations
- C.
Cause and effect
- D.
The goals of psychology
Correct Answer
C. Cause and effectExplanation
The experiment is the only research method that allows researchers to determine cause and effect relationships. In an experiment, the researcher manipulates an independent variable and observes the effect it has on a dependent variable. This allows them to establish a cause and effect relationship between the variables. Other research methods, such as surveys or observations, can only establish correlations or relationships between variables, but cannot determine causation. Therefore, the experiment is the most valuable method for determining cause and effect in research.Rate this question:

An experimenter wishes to see if there is a difference between the two types of memory techniques. She taught one group of participants Technique A and another group Technique B. Then, she gives each group a list of words to memorize. Two weeks later, she tested the participants to measure how many words they remembered. What is the dependent variable in this experiment?
- A.
Number of words in the list
- B.
Memory techniques
- C.
Sex of the experimenter
- D.
Number of words remembered
Correct Answer
D. Number of words rememberedExplanation
The dependent variable in this experiment is the number of words remembered. This is because the experimenter wants to measure the effect of the different memory techniques (independent variable) on the participants' ability to remember words. By comparing the number of words remembered by each group, the experimenter can determine if there is a difference between Technique A and Technique B in terms of their effectiveness in memory recall. The other options provided - number of words in the list, memory techniques, and sex of the experimenter - are not the focus of the experiment and therefore not the dependent variable.Rate this question:
