The purpose of this thesis was to increase understanding about the infuence temperamental reward and punishment sensitivities may exert on motivation in a learning context. Following theory and findings from temperament research, reward sensitivity was viewed as diferentiated into dimensions defined by the source of reward. Accordingly, an instrument
with scales for measuring punishment sensitivity and two main dimensions of reward sensitivity, compiled from items in previous temperament research, was taken into use and validated. Motivation was approached as students’ relatively stable motivational tendencies (i.e., achievement goal orientations), and appraisals of domain- and course-specifc interest, strain, and effort.
The thesis comprises three original articles, reporting research conducted among students of different ages and educational stages. Two of the articles consist of two studies utilising diferent data sets. In Article I, the dimensional structure of temperamental sensitivities was examined among general upper-secondary students (Study 1; N = 157) and university
students (Study 2; N = 506). Further, in Study 2, the predictive effects of reward and punishment sensitivities on achievement goal orientations (mastery-intrinsic, mastery-extrinsic, performance-approach, performance-avoidance, work-avoidance) were also inspected. In Article II, the developmental interrelationships between temperamental sensitivities and achievement goal orientations (mastery, performance-approach, performance-avoidance, work-avoidance) were followed over the first three years of elementary school (N = 212). Finally, in Article III, the impact of temperamental sensitivities on appraisals of interest, strain, and effort was investigated among eighth-graders in the domain of mathematics (Study 1; N = 268), and over the duration of a course in four different subjects among general upper-secondary students (Study 2; N = 155).
Variable-centred methodological approaches revealed the following findings. Firstly, factor analyses confirmed the assumed factorial structure of punishment sensitivity and two main dimensions of reward sensitivity, namely, interindividual reward sensitivity and intraindividual reward sensitivity. Interindividual reward is defined as being derived from other
people’s perceived or actual attitudes and actions, such as attention or praise, whereas the source of intraindividual reward is within the individual, in their own inner states and actions, such as enthusiasm and excitement over one’s own successes, and enjoyment of and seeking out novelty.
Secondly, in all studies, a pattern emerged showing the temperamental sensitivities to be associated with motivation in a consistent fashion, regardless of the age of the participants. Interindividual reward sensitivity was connected with lower mastery strivings, higher concerns over the adequacy of one’s performance respective to others (i.e., performance-approach and performance-avoidance orientations) and work avoidance, as well as with higher psychological strain in the course context. Likewise, punishment sensitivity, although somewhat less related to motivation than expected, showed links with heightened performance concerns and higher experiences of strain in the domain context. In contrast, intraindividual reward sensitivity was found to be associated with higher mastery strivings
as well as higher interest appraisals and willingness to exert effort.
Overall, the findings support considering reward sensitivity as comprising dimensions based on the source of reward, and indicate that temperamental sensitivities have a role in guiding motivation in adaptive and maladaptive ways, academically and as regards well-being. It is
therefore argued that these sensitivities should be taken into account as antecedents to students’ motivation, in both educational research and practice.
