Sigmund Freud is the founder of the psychoanalytic school of thought. He developed the theory of psychoanalysis, which focuses on the unconscious mind and the role it plays in shaping human behavior. Freud's ideas revolutionized the field of psychology and had a significant impact on the understanding and treatment of mental disorders.

The left hemisphere of the brain is responsible for processing language and speech, which includes the ability to understand and perceive sounds. This is known as the left hemisphere dominance for language. As a result, sounds are processed more quickly in the left hemisphere, leading to a faster registration of sounds in the left ear compared to the right ear.

Dendrites are the branchlike structures of a neuron that receive information from another neuron. They are responsible for receiving signals and transmitting them towards the cell body or soma. Dendrites play a crucial role in the communication between neurons, as they receive incoming signals and integrate them to determine whether the neuron should fire an action potential or not.

The temporal lobe is associated with hearing. It is located on the sides of the brain, above the ears. This lobe plays a crucial role in processing auditory information and is responsible for interpreting sounds and language comprehension. It also contributes to memory formation and emotional responses.

A hypothesis is a tentative prediction about the relationship between two variables. It is a statement that can be tested and either supported or refuted through research and evidence. A hypothesis serves as a starting point for scientific investigations and helps researchers formulate specific research questions and design experiments to gather data and test the hypothesis. It is an essential component of the scientific method and plays a crucial role in advancing scientific knowledge and understanding.

A correlation coefficient measures the strength and direction of the relationship between two variables. The value of -0.97 indicates a strong negative relationship between the variables. This means that as one variable increases, the other variable decreases consistently. The closer the correlation coefficient is to -1 or 1, the stronger the relationship between the variables. Therefore, a correlation coefficient of -0.97 indicates the strongest relationship among the given options.

Roger Sperry's specialization was left and right brain research. This refers to his groundbreaking work on understanding the functional differences between the left and right hemispheres of the brain. Sperry conducted experiments on split-brain patients, which involved severing the corpus callosum (the bundle of nerves connecting the two hemispheres) to treat epilepsy. Through his research, Sperry discovered that the two hemispheres have distinct functions and abilities, leading to a better understanding of brain lateralization and cognitive processes.

The group that correctly describes central tendency is mean, median, and mode. Central tendency refers to the measure that represents the center or average of a set of data. The mean is calculated by adding up all the values and dividing by the number of values. The median is the middle value when the data is arranged in order. The mode is the value that appears most frequently in the dataset. These three measures help to understand the typical or central value of a set of data.

The correct answer is cerebellum, medulla, and pons. The hindbrain is the posterior section of the brain that is responsible for basic functions such as balance, coordination, and vital bodily functions. The cerebellum is involved in motor control and coordination, the medulla controls functions like breathing and heart rate, and the pons helps relay information between the cerebellum and the rest of the brain. These structures collectively make up the hindbrain.

G. Stanley Hall is the correct answer because he is known for founding the first psychology laboratory in the United States. He established the laboratory at Johns Hopkins University in 1883 and is considered a pioneer in the field of psychology. Wilhelm Wundt is often credited with founding the first psychology laboratory in general, but that was in Germany, not the United States.

Dopamine is a neurotransmitter that is correlated with movement, attention, and learning. It plays a crucial role in regulating various brain functions such as motor control, motivation, reward, and cognitive processes. Dopamine is involved in the brain's reward system, which reinforces behavior and promotes learning. It is also involved in regulating attention and focus, as well as coordinating movement and motor skills. Therefore, dopamine is the correct answer as it is closely associated with these functions.

The correct answer is phenotype. Phenotype refers to the observable physical characteristics of an individual, such as the color of their eyes, hair, and their height. In this case, the description of Jackson's brown eyes, brown hair, and height of 6' 1" are all part of his phenotype. Genotype refers to the genetic makeup of an individual, physiognomy refers to the facial features, somatype refers to the body type, and nerves refer to the nervous system.
