A hood for psychological experiments

Abstract

The invention discloses a hood for psychological experiments, which relates to the technical field of psychological experiment equipment, and mainly includes an outer cover made of hard materials, the outer cover is composed of a fixed cover and a movable cover movably installed at one end of the fixed cover A soft inner cover is installed inside the outer cover, a part of the edge of the inner cover is connected to the inner side of the fixed cover, and the other part of the edge is hung on the hanging ring, and the adjustment mechanism can adjust the height of the hanging ring inside the fixed cover. Adjust the tightness of the inner cover. When in use, open the movable cover to drive the inner cover to be stretched. The test object can easily put on the hood. After wearing it, close the movable cover and adjust the inner cover through the adjustment mechanism. Tighten the mask body until the entire inner mask body can fit the test subject's head tightly. The head cover of the present invention has the advantages of both the soft head cover and the hard head cover, is not only easy to wear but also can fit the head closely, and provides a strong guarantee for the collection of real EEG signals.

Description

technical field [0001] The invention relates to the technical field of psychological experiment appliances, in particular to a hood for psychological experiments. Background technique [0002] Psychology is a discipline that studies people's reactions in various environments and situations. Psychological research requires various experiments on test subjects to reveal or verify some theories. The reaction of the test object to the specific experimental environment can be recorded by various collection and recording equipment. The collected information includes sound, image and EEG signals, etc. The sound and image signals are usually collected by audio and video recording equipment, which belongs to non-contact collection. Moreover, the collected signal can reflect the real situation of the test object, while the EEG signal needs to be obtained by attaching the detection electrode to the head of the test object, which belongs to contact collection, so the stability of contac...

Problems solved by technology

[0004] There are many forms of hoods, the main forms are soft cloth or sandy hoods and hard plastic or metal material hoods. Soft hoods generally have a certain degree of elasticity to adapt to the head of the test object. However, it is inconvenient to wear because of the elasticity. Although the hard hood is more convenient to wear, it cannot adapt well to the shape and size of the test subject's head, resulting in some detection electrodes not being able to fit tightly. The head of the test subject, reducing the quality of the EEG signal
