Psychology as a Natural Science Exam
Study Guide with Complete Solutions
Sensation - Ans:✔✔-occurs when the receptors for sensory systems detect energy from the
external environment
Perception - Ans:✔✔-occurs when the information from sensation is processed within the CNS
Doctrine of Specific Energies - Ans:✔✔-receptors and neural channels for different senses are
independent
Labeled lines - Ans:✔✔-particular nerve cells are labeled for distinctive sensory experiences
Adequate stimulus - Ans:✔✔-the type of stimulus for which a given sensory organ is particularly
adapted
Transduction - Ans:✔✔-means by which physical energy is changed into neural impulses
Pacinian Corpuscle - Ans:✔✔-a receptor that detects vibration
Coding - Ans:✔✔-patterns of action potentials in a sensory system must reflect a stimulus
Adaptation - Ans:✔✔-progressive loss of response when stimulation is maintained
Suppression - Ans:✔✔-suppress irrelevant stimuli and note the important changes of stimuli

Receptive fields - Ans:✔✔-space in which a stimulus will alter a neuron's firing rate
Attention - Ans:✔✔-generalized state of awareness of inputs
Selective attention - Ans:✔✔-Brain only allows us to focus on one thing at a time
Hierarchical organization - Ans:✔✔-more important information is enhanced while extraneous
information is suppressed
Tonic - Ans:✔✔-little adaptation
Phasic - Ans:✔✔-display adaption
Olfactory epithelium - Ans:✔✔-sheet of cells in the nasal cavity where olfactory receptors are
located
Turbinates - Ans:✔✔-curved surface in the nasal cavity that directs air flow
Olfactory bulb - Ans:✔✔-complex structure at the anterior end of the brain where numerous
axons of the olfactory nerve terminate
Glomeruli - Ans:✔✔-spherical units containing mitral cells where synapses occur
Anosmia - Ans:✔✔-inability to smell
Pheromones - Ans:✔✔-Odor signals or trails secreted by animals
External ear - Ans:✔✔-collects sound waves and physically transforms sound energies
