To test the hypothesis, Cannon designed an innovative experiment in which A.L. Washburn swallowed a deflated rubber balloon attached to a tube. Once the balloon was inside Washburn's stomach, it was inflated. The pressure of the balloon against the stomach walls was used to measure the strength of contractions.
[6] [1] The experiment attempts to assess the subject's spatial reasoning. The subject is shown an upright bottle or glass with a water level marked, then shown pictures of the container tilted at different angles without the level marked and asked to mark where the water level would be.
Bechara and his colleagues explain these findings in terms of the somatic marker hypothesis. The Iowa gambling task is currently being used by a number of research groups using fMRI to investigate which brain regions are activated by the task in healthy volunteers [ 8 ] as well as clinical groups with conditions such as schizophrenia and ...
Experimental Design Diagram (EDD) is a diagram used in science to design an experiment.This diagram helps to identify the essential components of an experiment. It includes a title, the research hypothesis and null hypothesis, the independent variable, the levels of the independent variable, the number of trials, the dependent variable, the operational definition of the dependent variable and ...
An example of Neyman–Pearson hypothesis testing (or null hypothesis statistical significance testing) can be made by a change to the radioactive suitcase example. If the "suitcase" is actually a shielded container for the transportation of radioactive material, then a test might be used to select among three hypotheses: no radioactive source ...
When the valve is opened, the smaller balloon shrinks and the larger balloon expands. The two-balloon experiment is an experiment involving interconnected balloons. It is used in physics classes as a demonstration of elasticity. Two identical balloons are inflated to different diameters and connected by means of a tube.
A soda geyser is a physical reaction between a carbonated beverage, usually Diet Coke, and Mentos mints that causes the beverage to be expelled from its container. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle.
