This targeted form of between-person difference in salience has rarely been explored by researchers into job content, although it has been central in other areas such as vocational choice, where different perceptions of the attractiveness of tasks form the basis for classifying people. Its importance in the present framework is that ratings of core-task attractiveness (J4C) influence subjective well-being in ways that are typically ignored by research in this area. An environmental input yields less or more happiness not only as a function of the personal salience of its primary features (J4B as already described), but also in response to a salience judgment of the J4C kind, focusing on the personal attractiveness of core activities in the role.
