Micro-level Mechanisms of Identity Development: The Role of Emotional Experiences in Commitment Development

Based on Marcia’s theory, many researchers consider exploration and commitment as the main processes in identity development. Although some identity theorists have hypothesized that emotional experience may also be an important part of the mechanisms of identity development, empirical research to investigate this claim has been lagging behind. In this study, we shed light on the role of emotional experiences in micro-level commitment dynamics, and compare this to the role of exploration. We take a within-individual approach, and particularly focus on educational commitment. We collected weekly measurements among 103 first year university students over several months, resulting in 22 to 30 measurements for each individual. Every week, the students reported an important experience and accompanying positive and negative emotions, their level of educational exploration and commitment. We generated linear growth models for each individual separately, using Dynamic Linear Modeling. These individual models generate regression weights that indicate how strong the impact is of exploration, positive and negative emotional experiences on changes in micro-level commitment for each individual. Our main finding is that both positive and negative emotional experiences are indeed related to changes in educational commitment. Positive experiences, but surprisingly, also negative experiences, are related to increases in educational commitment for the majority of individuals. Moreover, for the large majority of individuals, the impact of emotional experiences is larger than the impact of exploration. Therefore, we conclude that it is highly likely that emotional experiences are an essential part of the micro-level mechanisms of identity development.

Modelling the individual process of career choice

Making a suitable career choice is a difficult task. Every year, many adolescents prematurely end their studies, commonly citing ‘having made the wrong choice’ as the main reason. This is a problem, both for the adolescents making these choices, and for society, which bears at least part of the cost of higher education. A thorough understanding of how adolescents make these career choices is essential to identifying the factors responsible for why the wrong choices are often made. Identity development theory emphasizes the role of exploration in career choice, but neglects many of the micro-level processes likely to play an important role. Similarly, traditional decision theory often focuses on optimization of choice, thereby neglecting the cognitive mechanisms that may explain deviations from optimal choice. Here, we present a novel computational approach to modelling long-term decision making. We combine elements of the macro-level theory on identity development with a firm rooting in micro-level cognitive processes. Specifically, we model decision making as an iterative process in which individuals can explore new options or more deeply investigate options that are already under consideration. The output of our model allows us to analyze how the quality of decisions depends on various factors, such as aspiration levels, the tendency to explore new options, and the ability to judge the fit of an option with one’s interests and capabilities. We present some preliminary results that already show our approach can lead to surprising conclusions, encouraging further development of this model in the future.

Micro-level processes of identity development: Intra-individual relations between commitment and exploration

We investigate intra-individual processes of identity at the micro level. With an intensive longitudinal design in the general context of higher education, we explore associations between changes in pivotal identity concepts: commitment and exploration and elaborate on how we conceptualize these concepts on a micro level. With our within-individual empirical approach, we revealed a large amount of variation between individuals with respect to the associations between exploration and commitment processes. At the same time, similarities were found amongst individuals, which help extend and clarify existing findings regarding identity development. Our findings highlight the necessity to, firstly, distinguish between micro- and macro-level identity processes. Secondly, and in the same vein, our findings emphasize the heterogeneous nature of micro-level identity processes, and the necessity to use a within individual approach to study these processes.
