Speaking Up or Holding Back? How Openness to Experience, Centralization, and Psychological Safety Shape Voice in Organizations
No full textThis research aims to understand the benefits of the personality dimension of openness to experience in organizational context. We draw from trait activation theory and RST to develop a model that considers personality and organizational dynamics that can create or hinder the social support necessary for employees to adopt voice behavior. Specifically, we argue that feelings of psychological safety emerge and encourage voicing from open individuals depending on the centralization dynamics in which they operate. We will test our theory using structural equation modeling with survey data collected from at least 150 participants, based on centralized and decentralized scenario
Category Coverage
No full textThis project will investigate the breadth of people's representations of the categories "men" and "women." We will evaluate the hypothesis that people's representations of gender categories differ not only in content, but in scope -- specifically, that conceptual representations of "men" are broader and more varied than conceptual representations of "women." Our project will address this question by probing people's "bottom-up" spontaneous descriptions and their "top-down" dimensional ratings of "men" and "women.
A systematic review and meta-aggregation of the experiences and perceptions of menstrual and hormonal contraceptive cycle-related symptoms in female athletes
No full textMenstrual cycle symptomology is common in sportswomen and could result largely in negative outcomes affecting various aspects of the individual’s sports participation and performance, quality of life and well-being. Despite this, the in-depth menstrual cycle symptoms experiences and perceptions of sportswomen have not been synthesised in the literature, hindering our understanding of how to create and implement suitable sportswomen-specific support systems to minimise negative outcomes. The objective of this review was to synthesise sportswomen’s experiences and perceptions of menstrual cycle symptomatology
Interactive Contrast: Investigating how conversational contrast affects event processing and attention in human–robot interaction
No full textOur recent studies are concerned with the effect of contrastive guidance as a form of explanans, on the recall of actions and thus action understanding. The study regarding the effectiveness of contrastive verbal guidance indicates that a visually contrastive context provides a more favourable situation for employing contrastive verbal guidance in the form of assertion and negation (Singh & Rohlfing, 2023). However, a limitation of the study was that verbal guidance was provided irrespective of whether the participant requested it or not. This approach does not align with real-life situations where contrastive guidance is used in response when it is asked for (Miller, 2021). To address this limitation and explore the impact of interaction, we propose a new experiment where an agent explains the task to the participant and provides contrastive or noncontrastive verbal guidance only upon request, in order to understand a requested action better. In this interactive experiment, the participant’s requests for clarification are categorized as open or restrictive. According to Dingemanse and Enfield (2015), open requests are more general, seeking information about the task in a broader sense (e.g., “Where?” or “How?”), while restrictive requests provide specific details regarding the source of misunderstanding (e.g., “Is it A or B?” or “Did you mean B?”). In our elicitation, we expect the participants to ask in a broader sense. This is because we omit either of the two crucial components of the action (path or manner), which would be required to complete the task. Studies suggest that these two components remain in the focus of attention due to their encodings in the verbal phrase (Talmy, 1985).
However, there is hardly any studies investigating these theories in the context of HRI and whether it extends beyond human–human interaction. To elicit participant requests, we design different contexts in which participants would need further information to fully comprehend the task and complete it with the assistance of the robot’s clarification. Crucially, these repairs will be provided either in a contrastive, using negation or in a noncontrastive manner, using assertion. The informativeness of negation will be tested in specific contexts that facilitate its use. We will use two different contexts: 1/4 and 2/4, following a previous non-interactive study by Nordmeyer and Frank (2023), but we aim to test the effect of contexts in an interactive setting. The contexts are created by varying the proportion of objects with the opposite feature compared to the rest of the objects. For instance, the contexts can be represented as 1/4 and 2/4, where the numerator indicates the number of objects with the contrasting feature. To gain insights into the online and offline processing of the explainee, attention distribution towards the explainer and the task, as well as cognitive loads during distinct phases of interaction (request initiation and repair), we will employ wearable eye-tracking technology. In summary, this experiment aims to investigate the impact of interaction (in the form of a request for clarification) on the processing of contrastive and noncontrastive verbal guidance. By utilizing a disjunctive task involving multiple manners and paths for object placement in a given context, we aim to expand our understanding of event cognition within an interactional framework.
Questions:
a) We aim to examine whether asking questions about missing information is positively related to the consolidation of the task.
b) We aim to analyse the processing of contrastive and noncontrastive repairs in response to the questions asked within the path and manner components. This will allow us to determine whether there are any differences in how participants process and respond to these types of repairs.
c) Another aspect we intend to explore is the effect of contexts, particularly the 1/4 and 2/4 contexts, on contrastive and noncontrastive processing.
d) To assess task load and attention allocation, we will measure fixation metrics (duration and rate) during two phases of interaction: a) request initiation, where we will consider the type of question asked (restricted vs. open), and b) repair, where we will analyze the type of repair provided by the partner (contrastive vs. noncontrastive). By examining these factors, we aim to gain insights into participants’ cognitive workload and the distribution of their attention throughout the interaction
