Can We Make Sense of the Notion of Trustworthy Technology?

In this paper we raise the question whether technological artifacts can properly speaking be trusted or said to be trustworthy. First, we set out some prevalent accounts of trust and trustworthiness and explain how they compare with the engineer’s notion of reliability. We distinguish between pure rational-choice accounts of trust, which do not differ in principle from mere judgments of reliability, and what we call “motivation-attributing” accounts of trust, which attribute specific motivations to trustworthy entities. Then we consider some examples of technological entities that are, at first glance, best suited to serve as the objects of trust: intelligent systems that interact with users, and complex socio-technical systems. We conclude that the motivation-attributing concept of trustworthiness cannot be straightforwardly applied to these entities. Any applicable notion of trustworthy technology would have to depart significantly from the full-blown notion of trustworthiness associated with interpersonal trust.     

Personal Publication Assistant: Abstract recommendations by a cognitive model

This paper discusses an analysis of how scientists select relevant publications, and an application that can assist scientists in this information selection task. The application, called the Personal Publication Assistant, is based on the assumption that successful information selection is driven by recognizing familiar terms. To adapt itself to a researcher’s interests, the system takes into account what words have been used in a particular researcher’s abstracts, and when these words have been used. The user model underlying the Personal Publication Assistant is based on a rational analysis of memory, and takes the form of a model of declarative memory as developed for the cognitive architecture ACT-R. We discuss an experiment testing the assumptions of this model and present a user study that validates the implementation of the Personal Publication Assistant. The user study shows that the Personal Publication Assistant can successfully make an initial selection of relevant papers from a large collection of scientific literature.     

Emotion Regulatory Strategies in Complicated Grief: A Systematic Review

Prolonged grief disorder, characterized by severe, persistent, and disabling grief, has recently been included in the International Classification of Diseases-11 (ICD-11). Emotional disturbances are central to such complicated grief responses. Accordingly, emotion regulation is assumed critical in the development, persistence, and treatment of complicated grief. Yet, a comprehensive review on this topic is lacking. We conducted a systematic review (PROSPERO: CRD42017076061) searching PsycInfo, Web of Science, and PubMed to identify quantitative research examining relationships between emotion regulation and complicated grief. Sixty-four studies on 7,715 bereaved people were identified, focusing on a variety of emotion regulation strategies (i.e., experiential avoidance, behavioral avoidance, expressive suppression, rumination, worry, problem solving, cognitive reappraisal, positive thought, and mindfulness). Our synthesis showed strong evidence that experiential avoidance and rumination play a role in the persistence of complicated grief. More generally, surveys support positive associations between putative maladaptive emotion regulation strategies and complicated grief, and negative associations between putative adaptive emotion regulation strategies and complicated grief. Laboratory research yielded mixed results. Emotion regulation is critical in complicated grief, and in particular experiential avoidance and rumination form important targets in complicated grief treatments. We advise expanding current knowledge, by employing more advanced, intensive data collection methods and experiments across diverse samples. Increasing knowledge in this domain will improve clinical practice.     

Upward and Downward Counterfactual Thought After Loss: A Multiwave Controlled Longitudinal Study

Counterfactual thoughts, mental simulations about how a situation may have turned out differently (i.e., “if only …, then …”), can reduce mental health after stressful life-events. However, how specific counterfactual thought types relate to post-loss mental health problems is unclear. We hypothesized that self-referenced upward counterfactuals (i.e., “If only I had done …, then the current situation would be better”) may serve as cognitive avoidance, thereby perpetuating loss-related distress. Conversely, downward counterfactuals (i.e., “If … had happened, then the current situation could have been [even] worse”) may facilitate benefit finding, thereby reducing distress. In a longitudinal survey, self-referent, other-referent, and nonreferent upward counterfactuals, and nonreferent downward counterfactuals were assessed at baseline. Prolonged grief and depression symptoms were assessed at baseline, and 6- and 12-month follow-ups. Multiple regression analyses assessed associations between counterfactual thoughts and symptom levels in 65 recently bereaved people who generated counterfactual thoughts about the loss-event. Moderator analyses assessed the unicity of significant effects in the previous step, by comparing these effects in 59 people generating loss-related counterfactuals with those in 59 propensity-score matched participants generating counterfactuals about other negative life-events. Multivariate analyses showed that nonreferent upward counterfactuals were uniquely strongly positively associated with prolonged grief and depression symptoms concurrently. Self-referent upward counterfactuals were uniquely positively associated with prolonged grief and depression symptoms longitudinally. Moderator analyses confirmed that thinking about how one’s (in)actions could prevent a death uniquely exacerbated prolonged grief and depression severity. Prolonged grief treatment may be improved by targeting self-blame and guilt.     

Consolidating behavioral and neurophysiologic findings to explain the influence of contextual interference during motor sequence learning

Motor sequence learning under high levels of contextual interference (CI) disrupts initial performance but supports delayed test and transfer performance when compared to learning under low CI. Integrating findings from early behavioral work and more recent experimental efforts that incorporated neurophysiologic measures led to a novel account of the role of CI during motor sequence learning. This account focuses on important contributions from two neural regions—the dorsal premotor area and the SMA complex—that are recruited earlier and more extensively during the planning of a motor sequence in a high CI context. It is proposed that activation of these regions is critical to early adaptation of sequence structure amenable to long-term storage. Moreover, greater CI enhances access to newly acquired motor sequence knowledge through (1) the emergence of temporary functional connectivity between neural sites previously described as crucial to successful long-term performance of sequential behaviors, and (2) heightened excitability of M1—a key constituent of the temporary coupled neural circuits, and the primary candidate for storage of motor memory.     

When views about alternative medicine,nature and god come in the way of people's vaccination intentions

In spite of the safety and efficiency of the COVID-19 vaccines and the many promotion efforts of political and expert authorities, a fair portion of the population remained hesitant if not opposed to vaccination. Public debate and the available literature point to the possible role of people's attitudes towards medical institutions as well as their preference for complementary and alternative medicine (CAM) on their motivations and intentions to be vaccinated. Other potential ideological factors are beliefs about environmental laissez-faire and divine providence insofar as they encourage people to let the pandemic unfold without human interference. In three cross-sectional samples (total N = 8214), collected at successive moments during the Belgian vaccination campaign, the present research examines the distal role of these psychological and ideological factors on vaccination intentions via motivational processes. Study 1 gauges the relation between trust in medical institutions and preference for CAM on intentions to get vaccinated via motivations. Study 2 examined the role of beliefs in the desirability of letting nature take its course (‘environmental laissez-faire beliefs’) on vaccination intention via motivations. Study 3 tests whether people's adherence to environmental laissez-faire and beliefs about divine providence are linked to their motivations for vaccination via trust in the medical institutions and CAM. Results show that adherence to CAM has a deleterious effect on vaccination intentions, whereas trust in medical institutions has a positive effect. Both ideological factors pertaining to external control are only moderately related, with environmental laissez-faire beliefs having stronger effects on CAM, medical trust and vaccination motivations. We discuss the importance of this set of results in light of the growing interest in CAM and the increasing presence of messages appealing to the environment.     

When Seemingly Irrelevant Details Matter: Hidden Covariation Detection Reexamined

Hidden covariation detection (HCD) theory states that when personality characteristics are surreptitiously associated with irrelevant features, these features obtain heuristic value for future evaluations of personality characteristics. According to the theory, subjects are not consciously aware of using such heuristics in their evaluations. We tested these hypotheses by confronting participants with statements that were said to belong to separate individuals, in which the apparent level of intelligence was associated with an irrelevant feature of the person who allegedly made these statements. In line with HCD theory, participants appeared to use this association, unconsciously, to guide their subsequent evaluations. Implications of these findings for HCD theory are discussed.     

Why Combine Logics?

Combining logics has become a rapidly expanding entreprise that is inspired mainly by concerns about modularity and the wish to join together tailor made logical tools into more powerful but still manageable ones. A natural question is whether it offers anything new over and above existing standard languages.By analysing a number of applications where combined logics arise, we argue that combined logics are a potentially valuable tool in applied logic, and that endorsements of standard languages often miss the point. Using the history of quantified modal logic as our main example, we also show that the use of combined structures and logics is a recurring theme in the analysis of existing logical systems.     

A note on the interpretability logic of finitely axiomatized theories

In [6] Albert Visser shows that ILP completely axiomatizes all schemata about provability and relative interpretability that are provable in finitely axiomatized theories. In this paper we introduce a system called ILP that completely axiomatizes the arithmetically valid principles of provability in and interpretability over such theories. To prove the arithmetical completeness of ILP we use a suitable kind of tail models; as a byproduct we obtain a somewhat modified proof of Visser's completeness result.Research supported by the Netherlands Organization for Scientific Research (NWO).
