Introduction: Various sensory experiences enable the normal development of children, which influences motor skills, health, cognitive and emotional development and the development of social skills. Children's play represents a central role in learning and in preparation for challenges. Important factors of child development are also the environment, parents and fast development of technology. Purpose: The purpose of diploma work was to explore the sensory experiences in preschool children using sensory strategies, the role of parents, technologies, children's motivation, just right challenge in performance of activities. We explored how motor skills and behavior of children changes in the process of one hour sensory activities, once a week, with an emphasis on tactile, proprioceptive and vestibular sensory inputs. Methods: The diploma work is based on a qualitative approach. In the theoretical part we used the descriptive method, while in the research we used the observation method with participation. The subject of research are sensory experiences in preschool children. The research population are children between three and five. The final sample included a group of sixteen children. We used the questionnaire for internal use, where we researched the correlation between the physical activities focused on three sensory systems, learning, behavior and involvement in the activities. The Pediatric Volitional Questionnaire was used for evaluation of volition during sensory activities. We searched for literature in Slovene, Croatian or English, by electronic bibliographic databases, books and professional journals of occupational therapy and other sciences that were published after 2000. We used electronic databases such as: DiKul, Google Scholar, OTSeeker, etc. Keywords: sensory integration, sensory strategies, preschool children, sensory integration activities, occupational therapy, vestibular system, tactile system, proprioceptive system, attention, MOHO, PVQ, just right challenge, kindergarten, the role of parents, technology. Results: In recurring sensory activities children improved and adjusted the performance of tasks. Self-confidence, balance, integration of both sides and motor planning were also improved. Inadequate behavior of the group did not occur in the week after the ending of sensory activities. Discussion and conclusion: Sensory activities contributed to motoric progress and adequate behavior of children, therefore, it is important to continue to incorporate elements of sensory strategies into the structured activities and play.
