| Question | Answer |
|---|---|
| What is the biological approach to psychology? | Concentrates on the aspects of the brain and nervous system. |
| What is the behavior approach to psychology? | Studies the behaviors that can be observed in regards to factors within one's environment. |
| What is the psychodynamic approach? | It centers around the unconscious mental processes and how they impact behavior, emotions, and thoughts. |
| What is the humanistic approach? | It believes that unconscious thought and environment do not determine behavior. Free will and altruism. |
| What is the cognitive approach? | Centers on mental processes such as: attention, perception, memory, thoughts, and problem solving. |
| What is the evolutionary approach? | Centers around how evolution influences behavior. Adaptation, reproduction, and natural selection helps understand behavior. |
| What is the sociocultural approach? | Centers on how behavior is impacted by one's culture and social environment. |
| What is cross-cultural research? | Comparison of research of various psychological attributes of individuals across cultures. |
| What is the scientific method? | Observation, hypothesis, experiment, drawing a conclusion, evaluating to conclusions. |
| What is the theory? | An effort to explain a phenomenon through a generalized set of rules |
| What is a random sample? | A group selected at random in order to help do a survey |
| What is operational definition? | The manner in which to measure and observe a variable. |
| What are the independent and dependent variables ? | Independent variables are what's being changed dependent variables are what's being measured. |
| What is the central nervous system? | The brain and spinal cord which helps control and coordinate mental and physical actions. |
| What is the peripheral nervous system? | It links the brain and spinal cord to the body consists of the somatic and autonomic nervous systems. |
| What is the somatic nervous system? | Sensory nerves that send information from skin and muscles to the central nervous system. |
| What is the autonomic nervous system? | Sends information to and from internal organs. |
| What is the difference between the sympathetic nervous system and the parasympathetic nervous system? | The sympathetic nervous system awakens and excites the body the parasympathetic nervous system calms the body. |
| What is plasticity? | The ability to change. |
| What are afferent nerves? | Sensory nerves that send data to the brain and spinal cord. Communicate information regarding external environment and internal body processes. |
| What are efferent nerves? | Motor nerves that send data out of the brain and spinal cord. Communicate information to other areas of the body. |
| What are the parts of the neuron? | The cell body, dendrites, Axon, myelin sheath, and terminal buttons |
| What is the cell body? | Provide substances to develop and sustain the neuron. Also known as the nucleus. |
| Dendrites | Fibers that receive and transmit information to the cell body. |
| Axon | Transmits information from the cell body to other cells. |
| Myelin sheath | Fat cells that are outside the axon and also insulate it |
| Terminal buttons | Stores and releases neurotransmitters |
| What are neurotransmitters and what do they do? | Chemicals in the brain and located in the terminal buttons. Transmit information between neurons |
| What are the six types of neurotransmitters? | Acetylcholine, norepinephrine, dopamine, serotonin, GABA, and endorphins. |
| What are the parts of the hindbrain? | Medulla oblongata, Cerebellum, pons, brainstem |
| What does the midbrain do? | Transmits information from the eyes and ears to the brain and transmits information regarding visual attention. |
| What is the forebrain? | The largest part of the brain |
| What is the hindbrain? | The oldest part of the brain. |
| What are the parts of the limbic system? | Amygdala, hippocampus, thalamus, basal ganglia, Hypothalamus, cerebral cortex. |
| What are the lobes of the brain? | Occipital lobe, temporal lobe, frontal lobe, parietal lobe. |
| What does the medulla oblongata do? | Regulates vital unconscious functions such as breathing, heart rate, and digestion. |
| What does the cerebellum do? | Involved with motor coordination in the arms legs and balance. |
| What does the pons do? | Connects the cerebellum to the brainstem |
| What does the brainstem do? | Attaches to the spinal cord. Regulates basic functions for survival as well as determines alertness. |
| What does the amygdala do? | Associated with distinguishing objects vital to survival such as food and water. |
| What does the hippocampus do? | Stores memories. |
| What does the thalamus do? | Sorts and allocates sensory information to the appropriate areas within the forebrain |
| What does the basal ganglia do? | Assist with control and coordination of voluntary movement. |
| What does the hypothalamus do? | Monitor is eating and drinking emotions and stress. Helps direct endocrine system and regulates body's internal state. |
| What does the cerebral cortex do? | Manages sensory and motor functions. |
| What does the occipital lobe do? | Manages processing of visual information. |
| What does the temporal lobe do? | Involved with processing memory, auditory and language |
| What does the frontal lobe do? | Involved with involuntary muscle management, personality and intelligence. Involved with cognitive function. |
| What does the parietal lobe do? | Involved with the archiving of motor control, spatial orientation and attention. Helps determine how far away something is. |
| What is the corpus callosum and what does it do? | The part that connects both sides of the brain together. Involved with transmitting data between the left and right hemisphere of the brain. |
| What is sensation? | The process of receiving stimulus energies from external environment and transforms them into neural energy. |
| What is perception? | The process of organizing and interpreting sensory information so that it makes sense. |
| What do sensory receptor cells do? | Register a stimulus â that energy is converted into electrochemical impulses that relay information to the brain. |
| What are the classes of sensory receptors? | Photoreception, mechanoreception, chemoreception. |
| What are all the parts of the eye? | Iris, pupil, lens, cornea, retina, sclera, optic nerve, fovea , Rods, cones. |
| What are all the parts of the ear? | Pinna, External auditory canal, eardrum, hammer, anvil and stirrup, oval window, cochlea, basilar membrane |
| What are Thermo receptors? | Sensory nerve endings under the skin that respond to temperature changes. |
| What is pain? | The sensation that warns us of damage to our bodies. |
| What is taste? | The detection of chemicals dissolving in saliva. Recognized through The papillae on the tongue. |
| What is smell? | The detection of airborne chemicals. |
