Dymesha watches her older sister do headstands. dymesha falls over when she attempts to do a headstand herself. she watches her older sister more carefully, and she notices that her sister leans backward slightly to complete her headstand. dymesha is then able to do headstands herself. which type of learning is this? a. classical b. conditioning c. observational d. operant

The correct answer is C. observational.

Explanation:

Observational learning requires a process where the person watches something and can replicate it with the new knowledge gotten from seeing the way another person does it and how it turns out positively for that other person. In this case, seeing how the body should be assembled in order to reach a headstand, allowed the girl to do it herself.

martians or other types of aliens represent a unique fear as opposed to zombies. vampires and other types of monsters.   in most sci-fi stories, aliens come from other worlds and have different or more advanced technology.   abductions and experimentation on human bodies that involve these technologies, or the use of these technologies against human beings and the use of unknown "powers", are a type of fear that's different from that of other types of monsters.
