In ecology‚ competition occurs between any organisms living in a mutual habitat. Competition can either be harmful or helpful to each organism‚ whether it is for food‚ water‚ shelter‚ etc. There are two basic types of competition: intraspecific competition or interspecific competition. Intraspecific competition is the competition that occurs between the individuals of the same species (T. Smith & R. Smith pg. 222). On the other hand‚ interspecific competition is the competition that occurs between

TWO-PROCESS THEORIES AND STROOP EFFECT: STUDYING THE EFFECT OF COLOUR CORRELATED WORDS (IV) vs. NEUTRAL WORDS WHEN RECORDING RESPONSE TIMES (DV) FOR IDENTIFYING THE INK COLOUR IN WHICH A WORD IS PRINTED. Abstract The idea of two-process theories and the Stroop effect are assessed in this experiment. The intention is to look for a predicted pattern between the response times of two separate conditions; one using a list of words that are colour related‚ such as “lemon” and another list of words which

is the variable held constant in an experiment that never changes and isn’t meant to be changed e.g. Statistics‚ a person‚ a group and an event etc. The control variable controls the experiment. Hypothesis- a hypothesis is much like a theory‚ but with more background evidence supporting the hypothesis. Dictionary answer: 1) A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. 2) A proposition made as a basis for reasoning‚ without

Relationship between Absenteeism and Job Performance Introduction Absenteeism has long been considered a significant and pervasive problem in industry. As a result‚ theories have been developed and numerous studies conducted to identify the causes of absenteeism. Probably one of the most common theories is the notion that absenteeism is caused by employees avoiding a painful or dissatisfying work situation. By the same token‚ this hedonistic theory would predict that employees who find

Frog Blood: Analysis: 1. The shape of the frog blood cell was in a circle‚ or oval. The edges were a little irregular‚ but it could still be identified as‚ basically‚ a circular shape. 2. The cells were produced by an animal‚ a frog. 3. The cell wall was not present

water is clear. A hypothesis is a tentative explanation of the observations. The hypothesis is not necessarily correct‚ but it puts the scientist’s understanding of the observations into a form that can be tested through experimentation. Experiments are then performed to test the validity of the hypothesis. Experiments are observations preferably made under conditions in which the variable of interest is clearly distinguishable from any others. If the experiment shows that the hypothesis is incorrect
