Principle
With this experiment, you can find evidence of the electrical activity that is generated during the movement of your eyes. Several electrodes attached to the skin of the face measure all the changes of the electrical voltage that are caused by the mov ...
The skin temperature measured at the fingertip diminishes visibly when someone is smoking. The change in the skin temperature depends on the text subject and their smoking habits. With heavy smokers ...
With this experiment, you can determine your own personal reading speed. One's reading speed can be trained and is an important prerequisite for the proper handling of all kinds of texts. You can precisely study the movement of your eyes during the m ...
Principles and tasks
To localize a source of sound using an artificial head. To measure the time difference and the difference in intensity of the sound waves incident on each ear of the artificial head.
What you can learn about
Priciple and tasks:
To test the reaction of shoots, leaves and roots of higher plants to light stimuli (photoperiodism) and to stimuli caused by the earth's field of gravity (geotropism). To measure the alignment of shoot, leaf and root of bean seedlings which sprout in a ves ...
Principle and tasks
To measure the alignment of shoots and roots under the effect of centrifugal forces which are less than, equal to or greater than gravity. To raise sunflower seedlings in small beakers in a rotating drum. To set different centrifugal forces ...
To test the temperature demands of poikilothermic animals. Using their thermoreceptors the animals recognize the temperature which suits them, gather in an area at the corresponding temperature (thermotaxis) and thus show their preferred temperature. To pr ...
To prepare curves demonstrating the regulation of body temperature. To discuss different curves depending on the conditions at the hand of the test person.
Demonstration of the regulation of body temperature.
Tasks:
Behavioural physiological measurement of the time resolving capacity of the compound eye of flies (without electrophysiological leads).
Tasks
Determination of the visual field of the right and left eye for white, blue, red and green. Detection of any visual field deficiency (scotoma). Location of the blind spot (site of optic nerve emergence). The extent of the visual fields of bo ...
To determine the flashing frequency of an LED at which the impression of a continuous light just occurs. To change the direction of incidence of the light using a perimeter. To determine the flicker fusion thershold of the left and right eye in relation to ...
Measurement of dead time in a reaction test. Analysis of the tansient response. Determination of threshold frequency for stimuli. Study of the effects of noise and alcohol on reaction capacity. The test subject should follow a rectangular cu ...
To record the changes in the elctrical field induced by eye movements, using electrodes stuck to the skin near the eyes.
To measure an electrooculogram (EOG) with a practised reader, a less practised ( ...
Production of mixed colours and white light by superimposed projection (additive mixing) of red, blue, and green light.
