The aim of this dissertation is to examine how adult learners with a spoken language background who are acquiring a signed language, learn how to use the space in front of the body to express grammatical and topographical relations. Moreover, it aims at investigating the effectiveness of different types of instruction, in particular instruction that focuses the learner's attention on the agreement verb paradigm. To that end, existing data from a learner corpus (Boers-Visker, Hammer, Deijn, Kielstra & Van den Bogaerde, 2016) were analyzed, and two novel experimental studies were designed and carried out. These studies are described in detail in Chapters 3–6. Each chapter has been submitted to a scientific journal, and accordingly, can be read independently.1 Yet, the order of the chapters follows the chronological order in which the studies were carried out, and the reader will notice that each study served as a basis to inform the next study. As such, some overlap in the sections describing the theoretical background of each study was unavoidable.

Introduction: Few studies have examined the sales of stolen account credentials on darkweb markets. In this study, we tested how advertisement characteristics affect the popularity of illicit online advertisements offering account credentials. Unlike previous criminological research, we take a novel approach by assessing the applicability of knowledge on regular consumer behaviours instead of theories explaining offender behaviour.Methods: We scraped 1,565 unique advertisements offering credentials on a darkweb market. We used this panel data set to predict the simultaneous effects of the asking price, endorsement cues and title elements on advertisement popularity by estimating several hybrid panel data models.Results: Most of our findings disconfirm our hypotheses. Asking price did not affect advertisement popularity. Endorsement cues, including vendor reputation and cumulative sales and views, had mixed and negative relationships, respectively, with advertisement popularity.Discussion: Our results might suggest that account credentials are not simply regular products, but high-risk commodities that, paradoxically, become less attractive as they gain popularity. This study highlights the necessity of a deeper understanding of illicit online market dynamics to improve theories on illicit consumer behaviours and assist cybersecurity experts in disrupting criminal business models more effectively. We propose several avenues for future experimental research to gain further insights into these illicit processes.
The revolutionary dimension of technological developments is all too often placed in the foreground, painting a picture of a future we can hardly imagine, let alone perceive. This book emphasises the evolutionary dimension of developments, and how we take small steps. How certain underlying, invariable aspects survive hype after hype, and have their own rhythm or longue durée. It is the search for where change meets inertia. Progression is a balance between the familiar and the unfamiliar. The essays bundled in this book have as a leitmotiv this attention to how progression is a matter of locating the small steps we can take and the invariables that lie beneath developments that stimulate or hinder certain big steps forward. It concentrates on the zone of proximal development, to use the term of Vygotsky. This collection of essays represents a personal view of the area where psychology, media, technology, and culture meet in the context of technological and social developments. These crossroads are addressed through topics such as digital identities, interactive media, the museum visitor in a digital world, and growing up in a digital society.
