Introduction: Aging is a natural and irreversible process and brings with it certain difficulties such as health problems, weakening of mental and physical functions, and existential problems and social exclusion. Stereotypical notions of age are a reflection of the generalization of mostly negative characteristics of that age to the whole group of the elderly, and relate to: physical, intellectual and sexual impotence, poor memory, rigidity in opinions, dependence on others and others. Objective: To identify the most common stereotypes and prejudices about the elderly and to examine the amount of knowledge about the third age that respondents have. Research methods: The research will be conducted with a questionnaire "Test scale on the meaning of your attitude about the elderly (semantic differential)" among students of the Undergraduate Professional Study of Nursing at the University of Dubrovnik, and students of the Maritime Department of the University of Dubrovnik. For statistical analysis of the obtained data, the software system SPSS for Windows (version 23.0, SPSS Inc, Chicago, Illinois, USA) and Microsoft Excel (version Office 2010, Microsoft Corporation, Redmond, WA, USA) were used. Results: In our results, certain prejudices proved to be correct, namely that more than half of the respondents considered the elderly to be ill (74%), with a statistically significant difference found between the two groups of students (p <0.001), where 84% of maritime college students consider the elderly to be ill. A statistically significant difference (p <0.001) was also found in questions related to: diligence and laziness, usefulness and uselessness, mobility of the elderly, as well as in questions related to social status.
