    What is the correlational method?

    • Research methods that yield descriptions of behaviour rather than causal explanations.

    • A research method used to establish the relationship between two characteristics, events, or behaviours.

    • A method whereby researchers use interviews to gather information about the attitudes, beliefs, experiences, or behaviours of a group of people.

    Correct Answer
    A. A research method used to establish the relationship between two characteristics, events, or behaviours.
    Explanation
    The correlational method is a research method used to establish the relationship between two characteristics, events, or behaviors. It involves measuring and examining the degree to which two variables are related to each other, without manipulating any variables or determining causality. This method helps researchers understand the strength and direction of the relationship between variables, which can provide valuable insights and predictions about behavior.

    What unit is frequency measured in?

    • Seconds

    • Hertz

    • Pitch

    • Decibels

    Correct Answer
    A. Hertz
    Explanation
    Frequency is a measure of how many times an event occurs in a given time period. It is commonly used to describe the number of cycles or vibrations of a wave per second. Hertz (Hz) is the unit used to measure frequency, specifically the number of cycles or oscillations per second. Therefore, Hertz is the correct answer for the unit of measurement for frequency.

    The Independent Variable is...

    • The factor measured at the end of the experiment

    • The control for selection bias.

    • The factor that is manipulated.

    • Information obtained using interviews or questionnaires.

    Correct Answer
    A. The factor that is manipulated.
    Explanation
    The independent variable is the factor that is manipulated in an experiment. It is the variable that the researcher intentionally changes or controls to observe its effect on the dependent variable. This allows the researcher to determine if there is a causal relationship between the independent variable and the outcome being measured. By manipulating the independent variable, researchers can test hypotheses and draw conclusions about cause and effect relationships in their experiments.

    The process through which the senses detect sensory information and transmit it to the brain is called:

    • Perception

    • Sensation

    Correct Answer
    A. Sensation
    Explanation
    Sensation refers to the process by which our senses detect and receive sensory information from the environment. It involves the initial detection of stimuli through our sensory organs such as the eyes, ears, nose, tongue, and skin. This information is then transmitted to the brain for further processing and interpretation. Perception, on the other hand, refers to the process of organizing, interpreting, and giving meaning to the sensory information received. Therefore, sensation is the correct answer as it specifically relates to the detection and transmission of sensory information to the brain.

    The two major theories that attempt to explain hearing are:

    • Conductions theory and place theory

    • Hair-cell theory and frequency theory

    • Place theory and frequency theory

    • Conduction theory and hair-cell theory

    Correct Answer
    A. Place theory and frequency theory
    Explanation
    The correct answer is place theory and frequency theory. Place theory suggests that different frequencies of sound stimulate different areas of the cochlea, which is responsible for hearing. This theory explains how we perceive different pitches. Frequency theory, on the other hand, proposes that the perception of pitch is determined by the frequency of the sound wave, with higher frequencies resulting in higher pitches. Both theories play a significant role in explaining how we perceive and understand sound.

    The sympathetic nervous system restores the body's functions to normal once a crisis has passed.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The parasympathetic nervous system restores the body's functions to normal once a crisis has passed.

    Plasticity is

    • Qualitative

    • Quantitative

    • Neither

    • Both

    Correct Answer
    A. Both
    Explanation
    Plasticity refers to the ability of a material to undergo permanent deformation without breaking. It can be both qualitative and quantitative. Qualitatively, plasticity refers to the general property of a material to deform under stress. Quantitatively, plasticity can be measured and characterized using parameters such as yield strength, strain hardening, and ductility. Therefore, plasticity can be understood from both a qualitative and quantitative perspective, making the answer "Both" correct.

    The hypothalamus regulates all of the following except:

    • Internal body temperature

    • Hunger and thirst

    • Coordinated movement

    • Sexual behaviour

    Correct Answer
    A. Coordinated movement
    Explanation
    The hypothalamus is a small region in the brain that plays a crucial role in maintaining homeostasis and regulating various bodily functions. It is responsible for regulating internal body temperature, hunger and thirst, and sexual behavior. However, it does not directly control coordinated movement. Coordinated movement is primarily regulated by other brain regions such as the cerebellum and basal ganglia. The hypothalamus mainly focuses on maintaining physiological balance and controlling basic survival functions.

    Where are the smell receptors located?

    • Olfactory tract

    • Olfactory nerve

    • Olfactory epithelium

    • Olfactory bulbs

    Correct Answer
    A. Olfactory epithelium
    Explanation
    The olfactory epithelium is the correct answer because it is the location where the smell receptors are located. The olfactory epithelium is a specialized tissue found in the upper part of the nasal cavity, and it contains millions of olfactory receptor cells that are responsible for detecting and transmitting smells to the brain. These receptor cells are equipped with specialized proteins that bind to odor molecules, triggering a signal that is then sent to the brain for interpretation.
