CCN1017 Introduction to Psychology Experimental Design Research Question: Would the packaging of a famous brand affect people’s rating on a product? Introduction Many people believe that brand names tell the quality of a product (Erdem‚ 1998). They tend to choose products on a basis of brands. Yet‚ it was found that many people enjoy drinking their favourite beer the most only when the brand label are shown.

Purpose: To investigate the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher

Describe the physiological approach to the study of the mind. Explain how Donders experiment can be repeated in a modern laboratory using the physiological approach to the study of the mind Donder’s work attempts to describe the processes going on in the mind‚ by analyzing cognitive activity into separate stages. Until Donder’s work‚ many scientists had assumed that the mental operations involved in responding to a stimulus occurred instantaneously. Donder was particularly interested in "timing

in humans (Caplan‚ 286). The most well known experiments in this regard were the experiments conducted on twins at Auschwitz. The other goal of the Nazi scientists was to provide human data that could be applied to the war effort. Experimentation of this sort mainly probed the extremes‚ which the human body could tolerate in a hostile environment. The most famous experiment of this sort was the Dachau Hypothermia Study.’ The rationale of the experiments was as follows: "A consequence of air combat

Popcorn Experiment Experiment performed on 8/26/11 Biology 101 Introduction: “The oldest popcorn ever found was discovered in the “Bat Cave” of central New Mexico. Archaeologists found 80‚000-year-old corn pollen below Mexico City”. “The popcorn was thougt to be about 5‚600 years old”. (www.factmonster.com/spot/popcorn1.html) This particular pollen is almost identical to today’s popcorn pollen. Researchers came up with the theory that popcorn could have been a Stone Age snack for “cave
