- Bounded rationality
My main research interests are the influence of emotions on cognitive processes, both elementary (e.g.working memory) and complex (decision making), and the adaptive role of emotions. The following are the research projects I am involved in:
The influence of emotional arousal on the selection of decision strategies
The problem investigated in the project was the function of emotions as modulators of information processing during decision making. The main aim of this project was to determine whether people under high emotional arousal have a greater tendency to use simple decision heuristics compared to people under low emotional arousal. A computerized multi-attribute choice task was used to see how much information people search before making a decision, whether they integrate this information, and whether these processes differ under different levels of emotional arousal.
Epistemic motivation, emotions and decision making
The problem analyzed in this project is how the motivation to avoid cognitive closure moderates the influence of emotional arousal on pre-decisional information processing. Motivation to reach cognitive closure is the motivation to have a clear understanding of the situation and have a clear knowledge what to do in a given situation. It is hypothesized that it influences the amount of information acquired and processes before making a decision and thus can moderate the negative effect of high emotional arousal on information search. In studies designed to explore this relationship, participants who were highly emotionally aroused were given either an instruction to reach cognitive closure or to avoid it and their predecisional information search was observed in a computer based decision task.
A simple bottom-up model of strategy selection
This project is aimed at understanding the process by which people select decision strategies in order to solve particular decision tasks. To this end, a computational model has been developed, which includes parameters important for complex cognitive functioning (e.g. working memory capacity and selective attention). The motivation behind this project is to understand the influence of various factors (e.g. emotions, task complexity, time pressure or individual differences) on human decision making. The model will be tested ex post on the data coming from several projects.
Individual differences in decisiveness and elementary cognitive processes
Decisiveness is defined as a tendency to make decisions fast and is associated with the use of simple decision strategies. This project investigates the possible determinants of Decisiveness – namely, basic cognitive processes, such as selective attention and working memory, as well as temperamental correlates of Decisiveness. Studies have been conducted to explore these relationships, e.g. to see whether low working memory capacity is associated with high Decisiveness.
Roles and emotions in social contract violations
The primary focus of the project was to investigate children’s understanding of specific emotions (guilt and anger) associated with violation of social contracts. The main question was whether children’s emotional responses to imagined social contract violations are moderated by the type of the relationship within which the violation took place. Specifically, children were asked whether violating a social contract with a biologically related person (sibling or parent) would result in lower guilt and anticipated anger relative to violating a contract with an unrelated person (friend or neighbour).
Health at birth, family structure and temperament
The problem analyzed in this project is the function of negative emotionality as a behavioral strategy for obtaining parental resources by children. The study focuses on children’s temperamental traits (especially negative emotionality – distress, frequent crying, fusing) and conditions which may influence the development of these traits in early infancy – namely, health at birth (birth weight, Apgar score) and the structure of family environment (sibship size, birth order and birth intervals). These variables are treated as determinants of parental investment, and children’s developing temperamental traits are understood as generalized behavior strategies for manipulating the investments.
