Introduction Memory is defined as the faculty by which the mind stores and remembers information(Eysenck & keane‚ 2010). Atkinson and Shiffrin (1968) (Cowan‚ Rouder‚ & Stadler‚ 2000)‚ came up with a model of sensory memory which stated not everything we perceive we process. Craik and Tulving (1975) developed an opposing theory in which they proposed the levels of processing theory‚ stating its not the processing but the type of quality of the processing that is performed‚ that determines the retention

The Effect of Metal Ions on Lichens Casey Stinnett ESC 1510 October 30‚ 2014 Introduction Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae‚ then supplies carbs‚ nitrogen‚ and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent‚ ranging all the way from

KCl (solid) Smoky Purple 1. The inaccuracies that may be involved in using flame tests for identification purposes is that there are certain ions that produce the same flame color and further identification must be made to identify the substance. 2. The pairs of ions that produce similar colors are K2CR2O7 and NaCl‚ Sn+2 and Zn+‚ and Ca2+ and Ni+2. 3. A flame test is a procedure used to test qualitatively for the presence of certain metals in chemical compounds. When the compound

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

The Effects of Individuals’ Detection of Changes in Images on Reaction Time Abstract The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color‚ location and disappearance and reappearance of images). These

Biology Lab Report November 4‚ 2013 Title: Starch Digestion by Pancreatic Amylase Statement of the Problem: What happens to enzymes when they are boiled? If digestion doesn’t occur‚ which will be present starch or maltose? If digestion does occur‚ which will be present starch or maltose? Hypothesis: I predict that when enzymes are boiled‚ they will become larger. If digestion does not occur starch will be present‚ and if it does occur maltose will be present. Materials: Test Tube

rate. The reactions include: 1.) NaHSO3 + H2SO4 H2SO3 + NaHSO4 *this reaction occurs quickly and is common to miss 2.) KIO3 + 3H2SO3 KI + 3H2SO4 3.) KIO3 + 3H2SO4 + 5KI 3K2SO4+3H20 +3I2 4.) I2 + H2SO3 + H20 H2SO4 + 2H + 2I 5.) I2 + starch starch I2 (blue-black color) Mathematically‚ we can use the Molarity formula to solve for the molarity of each solute (KI03 and NAHSO3) in order to later solve for the second concentrations of each using the M1V1=M2V2 formula. A graph will then be created
