Perception is a multiple process in which people select, organize, and present sensory stimulations. In this process, people's perceptions change and shape their current attitudes, beliefs, values and knowledge.When the consumer does not know the possible consequences of particular decisions, uncertainty arises and a perceived risk is created. Whether or not there is a real risk depends on the consumer perceiving it This final paper discusses the topic of perceived risk and its impact on consumer behaviour. It starts with the question; what is perception in psychology and how much is perception influenced by consumer behaviour. Furthermore, it questions what are the factors that influence the selectivity of perception, what are the stages of perception and some of the deceptions that should be considered in perception. It then analyses the application of perception in marketing and what the risk perception is and how it influences consumer behaviour. It also looks in what ways can the risk of consumer behaviour be reduced. All issues are presented and analysed in this paper. In the second part of the paper, in fact, in the empirical part, research was conducted to give us an insight into a better understanding of how the risks of online shopping affect the intent of further online shopping in the online marketplace. In this research we can see consumer behaviour. In addition to the above there is an analysis and interpretation of the research results presented in graphs based on the questions answered. Final conclusions and basic guidelines for the future of online shopping have been made to conclude the paper. When it comes to ordering mobile phones and IT equipment online, most participants are skeptical. Maybe because these are very valuable products, so going to the store gives them more safety. When it comes to the risk of online shopping, consumers have not specifically singled out any reason such as fear of security during online shopping, product damage, failure to meet their expectations and similar possible problems. Most of the participants plan to make greater use of online purchases of mobile phones and IT devices in the future.
