Evolution Lab The finches on Darwin and Wallace Islands feed on seeds produced by plants growing on these islands. There are three categories of seeds: soft seeds‚ produced by plants that do well under wet conditions; seeds that are intermediate in hardness‚ produced by plants that do best under moderate precipitation; and hard seeds‚ produced by plants that dominate in drought conditions. The lab is based on a model for the evolution of quantitative traits-characteristics of an individual that

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

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
