A negative correlation refers to a relationship between two variables where they move in opposite directions. This means that as one variable increases, the other variable decreases, and vice versa. In other words, when there is a negative correlation, the variables have a tendency to move in opposite directions from each other.

The cognitive perspective focuses on the important roles of mental processes in how people process and remember information. This perspective emphasizes the study of cognitive processes such as perception, attention, memory, language, and problem-solving. It suggests that our thoughts and mental processes play a crucial role in shaping our behavior and understanding the world around us. This perspective is interested in understanding how people acquire, process, store, and retrieve information, and how these processes influence behavior and decision-making.

Psychology is the scientific study of behavior and mental processes. It involves examining and understanding human and animal behavior, as well as the underlying cognitive processes. This field uses scientific methods to gather and analyze data, allowing researchers to gain insights into various aspects of human behavior and mental functioning. Psychology encompasses different perspectives, such as the biological and behavioral perspectives, which provide different frameworks for understanding behavior and mental processes.

Random selection refers to the process of choosing objects or individuals from a larger group in a way that ensures every member of the group has an equal chance of being included in the study. This method is commonly used in research to create a representative sample, where the selected objects or individuals accurately reflect the characteristics of the larger group. By using random selection, researchers can minimize bias and increase the generalizability of their findings to the entire population.

Naturalistic observation is a research method that involves observing and recording behaviors as they occur in their natural setting, without any interference or manipulation by the researcher. This method allows for a detailed and accurate understanding of behavior in its natural context, providing valuable insights into real-life behaviors and interactions. Correlation studies, surveys, and case studies are different research methods that are not specifically focused on observing behaviors in their natural setting.

Sigmund Freud was associated with the psychoanalysis theory and form of psychotherapy that emphasize the role of unconscious factors in personality and behavior. Freud believed that unconscious thoughts and desires greatly influence human behavior, and that by exploring and understanding these unconscious factors, individuals can gain insight into their own motivations and conflicts. This approach revolutionized the field of psychology and greatly contributed to our understanding of human behavior.

Dependent variables are the factors that are observed and measured for change in an experiment. They are the variables that are influenced by the independent variables, which are manipulated by the researcher. Dependent variables are the outcomes or results that are measured or observed to determine the effect of the independent variables. They are called dependent variables because their values depend on the values of the independent variables. In other words, changes in the independent variables cause changes in the dependent variables, and therefore, they are the factors that are observed and measured for change in an experiment.

Positive correlation refers to a relationship between two variables where they both vary in the same direction. This means that as one variable increases, the other variable also increases. In other words, there is a direct relationship between the two variables. For example, if we observe that as the temperature increases, the number of ice cream sales also increases, we can say that there is a positive correlation between temperature and ice cream sales.

B.F. Skinner is the correct answer because he was a renowned psychologist who extensively studied learning and the effect of reinforcement. He developed the theory of operant conditioning, which emphasizes the role of consequences in shaping behavior. Skinner conducted numerous experiments with animals and humans to understand how reinforcement influences behavior and learning processes. His work has had a significant impact on the field of psychology and continues to be influential in the study of behavior and learning.

The numerical indicator of the strength of the relationship between factors is called the correlation coefficient. It measures the degree of association between two variables, indicating how closely they are related. A correlation coefficient can range from -1 to +1, with a positive value indicating a positive correlation (both variables increase or decrease together), a negative value indicating a negative correlation (one variable increases while the other decreases), and a value close to zero indicating no correlation. The correlation coefficient helps to quantify the strength and direction of the relationship between variables.

The application of the principles of evolution to explain psychological processes and phenomena is known as the evolutionary perspective. This perspective suggests that human behavior and mental processes have evolved over time through the process of natural selection, in order to adapt to the environment and increase the chances of survival and reproduction. It emphasizes the importance of understanding how our ancestors' behaviors and traits have shaped our current psychological makeup. By studying evolutionary psychology, researchers can gain insights into various aspects of human behavior, such as mate selection, aggression, and decision-making.

A case study is an intensive, in-depth investigation that focuses on a specific individual or a small group of individuals. It involves gathering detailed information and analyzing various aspects of their behavior, experiences, and circumstances. This research method allows researchers to gain a comprehensive understanding of the subject(s) being studied and provides valuable insights into their unique characteristics, perspectives, and interactions. Case studies are often used in psychology, sociology, and other social sciences to explore complex phenomena and generate rich, contextualized data.

A representative sample is a segment that closely parallels the larger population being studied on relevant characteristics. It is a subset of the population that accurately represents the key characteristics of the entire population. This type of sample is important in research as it allows researchers to draw accurate conclusions about the population as a whole based on the characteristics and behaviors observed within the sample. By ensuring that the sample is representative, researchers can minimize bias and increase the generalizability of their findings.

Biological psychologists study the physical aspects of behavior and mental processes. This perspective focuses on understanding how biological factors, such as genetics, brain structure, and neurotransmitters, influence behavior and cognition. It seeks to uncover the underlying biological mechanisms that contribute to our thoughts, emotions, and actions. By examining the relationship between the brain and behavior, biological psychologists aim to gain insights into various psychological phenomena, including perception, learning, memory, and mental disorders.

Random assignment is the process of assigning participants to experimental conditions in a way that ensures that each participant has an equal chance of being assigned to any of the conditions or groups in the study. This is done to minimize any potential bias or confounding variables that could influence the results. By randomly assigning participants, researchers can increase the internal validity of their study and make more accurate conclusions about the effects of the independent variable on the dependent variable.

The experimental method is a research method used to demonstrate a cause-and-effect relationship between changes in one variable and the effect produced on another variable. This method involves manipulating an independent variable and observing the resulting changes in a dependent variable while controlling for other variables. By randomly assigning participants to experimental and control groups, researchers can establish a causal relationship between the independent and dependent variables. This method allows researchers to make inferences about causality and is widely used in scientific research.

The scientific method is a set of assumptions, attitudes, and procedures that guide researchers in their investigation process. It provides a systematic approach to creating research questions, generating evidence, and drawing conclusions. This method involves making observations, formulating hypotheses, conducting experiments or studies, analyzing data, and drawing conclusions based on the evidence gathered. It emphasizes objectivity, repeatability, and the use of empirical evidence to support or reject hypotheses. The scientific method is widely used across various fields of research to ensure reliability and validity in the findings.

A correlational study is a research strategy that allows for the precise calculation of how strongly related two factors are to each other. It involves measuring and analyzing the relationship between variables without manipulating them. By examining the correlation coefficient, which ranges from -1 to +1, researchers can determine the strength and direction of the relationship. A positive correlation indicates that the variables increase or decrease together, while a negative correlation suggests that as one variable increases, the other decreases. Therefore, a correlational study is the appropriate research strategy to calculate the strength of the relationship between two factors.

Purposely manipulated factors that are thought to produce a change in an experiment are known as independent variables. These variables are controlled and manipulated by the researcher to determine their effect on the dependent variable, which is the outcome or response being measured. By manipulating the independent variable, researchers can test the cause-and-effect relationship between variables and draw conclusions about the impact of the independent variable on the dependent variable.

A sample is a smaller subset of a larger group or population that is selected to represent the characteristics of the whole group. It is used in research and surveys to gather data and draw conclusions about the larger population. By studying a sample, researchers can make inferences and predictions about the entire group, saving time and resources compared to studying the entire population.
