Sensation and perception are the processes by which we absorb information from environmental stimuli and convert it into data that our brains and bodies use to modify behavior. This course will introduce you to these two closely related, though distinct, processes. We will begin with sensation, the physical process by which we use our sense organs (i.e. tongues for taste or noses for smell) to respond to the environmental stimuli around us. Perception, on the other hand, refers to our interpretation of stimuli. It occurs through cognitive processing and enables us to use information in order to change our behavior. While these processes may seem simple, they are just the opposite: large portions of the brain are devoted to the seemingly straightforward processes of seeing and hearing, and entire sensory organs have developed in order to facilitate them. Further, while the brain is constantly using the information it gathers to make decisions, we are entirely unaware of this activity. Unbelievably, studying il…

The SAT is a timed standardized test, taken by most students in their junior or senior year of high school, often required for college admission.  In the increasingly competitive college admission process, students today are looking for any and all ways to improve their candidacy.  One element of your college application that can definitely be improved on to help your chances of admission is your SAT score. The test is made up of 10 sections, drawn from three subjects: reading, mathematics, and writing.  All of these subjects review topics you have already learned in school: critical reading skills, arithmetic, algebra, geometry, grammar, and essay writing.  You already have basic knowledge on these subjects.  However, you can gain an extra edge and improve your score by reviewing the specific material that will be covered on the test and by becoming familiar with the rules and strategies specific to correctly answering SAT questions. Doing well on the test provides important information about you as…

Ecology is the study of interactions between organisms and between organisms and their environments.  Population ecology is the subfield of ecology that identifies those ecological factorsin the community or in the ecosystemthat regulate a population’s size. Ecosystems and communities involve complex interactions that have evolved over long periods of time.  The species that are present and the interactions we see between them are the result of evolution under the unique environmental pressures that exist in a given environment.  These interactions may be delicately intertwined, such that the loss of a single species from a community could mean the collapse of the entire community in a domino effect.  Thus, biologists are concerned with the preservation of biodiversity in ecosystemsretaining as many different species in the ecosystem as possible so the intricate relationships among species are preserved. In recent years, we have seen a decrease in the biodiversity of ecosystems.  Human activities a…
