Doppler effect The Doppler effect‚ named after Christian Doppler‚ is the change in frequency and wavelength of a wave as perceived by an observer moving relative to the source of the waves. For waves that propagate in a wave medium‚ such as sound waves‚ the velocity of the observer and of the source are relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from motion of the source‚ motion of the observer‚ or motion of the medium. Each of these

GREENHOUSE EFFECTS IntroductionThe greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases‚ and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere‚ it results in an elevation of the average surface temperature above what it would be in the absence of the gases.[1][2] Solar radiation at the frequencies of visible light largely passes through the atmosphere to

Introduction – This study researched the implications of the bystander effect when both gaze and no gaze methods were used. It tested this with woman to woman interaction only. The belief was that when gaze was held between the subject needing assistance and a random subject the expressed desire to help

CSI Effect Abstract Crime in America is increasing rapidly and many techniques have been created over the years in order to solve major crimes. Forensics science is one of the many techniques that have been created. Forensics is the use of science and technology to investigate and establish facts in criminal courts of law (free-dictionary‚ n.d). But there is an upcoming issue which involves the exaggerated details of forensics science. This paper explores the CSI Effect‚ compares and contrasts

Abstract The aim of this experiment is to study autonomic processes by replicating the previously carried out Stroop effect by using numbers. A number of 180 random participants aged in between 18-89 were recruited to participate in this experiment. Participants were presented with a stroop experiment task sheet which consists of three parts which was the control‚ congruent and incongruent conditions. Time was taken and recorded for each participant to say out the number of stars in the control condition

5/03/2013 Psychology The Stroop effect The human brain constantly responds to a lot of inputs of sensory information. Our brain tends to manages this by responding to one or more input(stimulus) at a time such is listening to music while watching tv‚ or ignoring inputs such as the background noise from the tv. But‚ sometimes our

(http://explorable.com/hawthorne-effect) The Hawthorne Effect is a well-documented phenomenon that affects many research experiments in social sciences. It is the process where human subjects of an experiment change their behavior‚ simply because they are being studied. This is one of the hardest inbuilt biases to eliminate or factor into the design. The History of the Hawthorne Effect The name is not the surname of a researcher‚ but the name of a place where the effect was first encountered. In 1955

THE BY-STANDER EFFECT So you may ask yourself…. Why do we automatically ignore the problem? One of the first steps in anyone’s decision to help another is the recognition that someone is actually in need of help. To do this‚ the bystander must realize that they are witnessing an emergency situation and that a victim is in need of assistance. Consequently‚ a major reason why eyewitnesses fail to intervene is that they do not even realize they are witnessing a crime. When we are in an ambiguous

A fascinating dimension of the bystander effect is the diffusion of responsibility. The general hypothesis that has been tested is: As the number of bystanders increases‚ it is less likely that any one onlooker will help (Darley and Latane‚ 1968). Social influence adds to this idea. Passive social influence from bystanders acts on the diffusion of responsibility and maximizes the bystander effect. Although pro-social behavior can be learned‚ because of social restraint exhibition of pro-social behavior
