This paper reports on a longitudinal research study on the attitudes to computers, and the perceptions of a computing career, of students enrolled in an introductory computing course in the years 1995 to 1998. Previous programming experience had a positive effect on computer confidence, and ownership of a home computer had a positive effect on computer anxiety and computer confidence. There was a gender difference in computer attitudes and perception of a computing career, with females scoring significantly lower than males on all measures. The analysis showed decreased computer liking over the semester and an inconsistent semester effect on computer confidence over the four years. The differences between male and female computer attitudes and perceptions of a computing career persisted over the semester.
