THE SUBJECT MATTER OF EXPERIMENTS A well-designed experiment tells us that changes in the explanatory variable cause changes in the response variable. More exactly‚ it tells us that this happened for specific subjects in the specific environment of this specific experiment. No doubt we had grander things in mind. We want to proclaim that our new method of teaching math does better for high school students in general or that our new drug beats a placebo for some broad class of patients. Can we

A. Stanford Prison Experiment- In this experiment‚ students volunteered to be a part of a psychology experiment that was being conducted at Stanford College. Because of the situation around them‚ they conformed to the environment‚ even though it was only a simple experiment in a Stanford hallway. Embarrassed and yet impressed‚ the experimenters stated this‚ “The negative‚ anti-social reactions observed were not the product of an environment created by combining a collection of deviant personalities

ABSTRACT The study us experimenters re-conducted was based on Norman Triplett’s study of social facilitation and how social presence or encouragement improves an individual’s speed and consistency in their performance. The experiment was replicated in using several trials for accurate results and was split into two stages: a mental challenge and a physical challenge. The two male and two female participants ranged from ages 15 to 17 years old. For the mental challenge‚ each participant was pulled

works. In our experiment we tested termite “handedness” – if termites prefer to turn left or right. We did this by placing a termite in an ink path with a fork in it which would cause the termite to choose between going left or right. The ink used in the experiment attracts termites insuring they will not run randomly in any direction. The data suggests that termites will prefer to turn left when given a choice even when the right path is identical to the left. Overall‚ this lab experiment lays the groundwork

SEEDLING GROWTH EXPERIMENT GEOS170C1 Fall 2014 Workshop 1 09/10/2014 Hypothesis: Electric energy can speed up the growth rate of plants. The access of an electric current can modifies the physic-chemical properties of the seed. It can charge the mitochondria‚ and intensifies other metabolic processes of the seed. This can achieve the purpose of sterilization‚ and enhanced the ability of absorbing water and oxygen. Prediction: The seeds that have been energized will sprout early than the control

Effects of Allelopathy on Plants Dates experiment was conducted: Purpose: The purpose of this experiment is to design a controlled experiment to see if a plant could survive living in eucalyptus tea. Allelopathy is when a plant gives off a bio-chemical that kills that plants around it‚ such as eucalyptus trees‚ black walnut trees‚ etc. My class went to the a eucalyptus grove and observed the eucalyptus trees. We noticed that there was a small circle around the tree that had nothing growing

Godden and Baddeley (1975) Godden and Baddeley under took a field experiment in which they investigated if being in the same environment when learning/remembering something affects their recall in appose to being in a different environment from where the words are learnt. They did using an independent group design. Godden and Baddeley found 18 deep-sea divers whom were given 38 unrelated two or three syllable words‚ they all

Investigation: The Stanford prison experiment was originally intended to run for a fortnight. However it lasted only 6 days and was ended earlier than initially planned due to the terrible living conditions and psychological problems that developed as the ‘inmates’ and ‘guards’ interacted.. The experiment was run by Philip Zimbardo‚ Craig Haney‚ David Jaffe‚ and W. Curtis Banks. The test subjects were young male college students that were chosen from 75 volunteers. The volunteers had replied to

Levels of Processing and memory The aim of the experiment is to investigate (a) whether level of processing (IV1) affects memory for words‚ (b) whether the intention to learn (IV2) has an effect upon memory and whether an effect of level of processing on memory for words is dependent upon intentionality of learning (IV1xIV2)‚ i.e. Is there an interaction effect? Levels of Processing is an influential theory of memory proposed by Craik and Lockhart (1972) which rejected the idea of the dual store

This essay will evaluate the use of observation as a method of study within psychology. Initially‚ the essay will discuss the two traditional methods of investigation experimentation and observation‚ before undertaking a deeper examination of the observational method itself. It will then consider where the use of the observational method has proven successful‚ with supporting evidence of research studies in which observation played a key role. Finally‚ the limitations of the observational method
