Problems with estimating trust in information sources are common in time constraining and ambiguous situations and often lead to a decrease of team performance. Humans lack the resources to track the integrity of information and thus tend to over- or under-rely on advice from support systems. Two types of adaptive team support have been...

Teams have become the norm for operating in dangerous and complex situations. To investigate how physical threat affects team performance, 27 threeperson teams engaged in a complex planning and problem-solving task, either under physical threat or under normal conditions. Threat consisted of the possibility that during task performance the...

Naval tactical picture compilation is a task for which allocation of attention to the right information at the right time is crucial. Performance on this task can be improved if a support system assists the human operator. However, there is evidence that benefits of support systems are highly dependent upon the systems' tendency to support. This...

Research on transactive memory has showed the positive effects of training together. This study investigated how feedback and reflection affect transactive memory in settings where there is no time for elaborate team training. Newly formed teams were given accurate, false or no feedback about their individual performance on a prior...

The development of Brain Computer Interfaces (BCIs) enters a phase in which these devices are no longer restricted to applications in controlled, single-task environments. For instance, BCIs for gaming or high-end operator stations will function as part of a multimodal user interface in a multitask environment. This phase introduces new issues...

The use of Wikipedia as an information source is becoming increasingly popular. Several studies have shown that its information quality is high. Normally, when considering information trust, the source of information is an important factor. However, because of the open-source nature of Wikipedia articles, their sources remain mostly unknown....

The decision making process during crisis events at the strategic level is often not effective or efficient, thereby hampering operational efforts. We have developed several tools to support strategic multi-party teams. After a 3 hour training session with mayors during a simulated crisis, these tools can be mastered.

The ability to interact with a constantly changing environment requires a balance between maintaining the currently relevant working memory content and being sensitive to potentially relevant new information that should be given priority access to working memory. Mesocortical dopamine projections to frontal brain areas modulate working memory...

When considering intelligent agents that interact with humans, having an idea of the trust levels of the human, for example in other agents or services, can be of great importance. Most models of human trust that exist, are based on some rationality assumption, and biased behavior is not represented, whereas a vast literature in Cognitive and...

This paper provides a closer look at how to support humans in the crisis loop, based on a thorough understanding of the macrocognitive functions that have to be fulfilled, such as naturalistic decision making, sensemaking, coordination and communication, and planning and adaptation. The objectives of the paper are to review work to date—along...

In the past few decades, the task of judging the credibility of information has shifted from trained professionals (e.g., editors) to end users of information (e.g., casual Internet users). Lacking training in this task, it is highly relevant to research the behavior of these end users. In this article, we propose a new model of trust in...

Objective: The ability to make inferences about knowledge, thoughts and feelings of others, i.e. perspective taking, is a key element of social cognition. Clinical observations indicate that Korsakoff patients may have impairments in social cognition, but studies are scarce. Also, executive dysfunction is present in Korsakoff patients, which may...

This prospective study examined how differences in coping style, coping self-efficacy, and metacognitive awareness influence coping behavior and performance during a realistic acute stressful exercise in 2 military samples (n = 122 and n = 132). Results showed that coping self-efficacy and coping style affected coping behavior, and that, in turn...

Results of a cross-cultural study of adult crying across 37 countries are presented. Analyses focused on country differences in recency of last crying episode and crying proneness and relationships with country characteristics. Three hypotheses on the nature of country differences in crying were evaluated: (a) distress due to exposure to taxing...

Prior studies have suggested that time pressure and task completion play a role in the occurrence of cognitive lockup. However, supportive evidence is only partial. In this study, we conducted an experiment to investigate how both time pressure and task completion influence the occurrence of cognitive lockup, in order to better understand...

In this paper it is explored whether personalisation of an existing computational model of attention can increase the model's validity. Computational models of attention are for instance applied in attention allocation support systems and can benefit from this increased validity. Personalisation is done by tuning the model's parameters during a...

At older ages, the circadian rhythm of body temperature shows a decreased amplitude, an advanced phase, and decreased stability. The present review evaluates to what extent these changes may result from age-related deficiencies at several levels of the thermoregulatory system, including thermoreception, thermogenesis and conservation, heat loss,...

Thirty-two subjects had tests of serial recall of visually presented nine-digit lists which were either presented in a single block of trials (constant context) or in between lists of much longer length (variable context). Other variables were vocalization-during-presentation versus silent memorization (within subject) and order of recall ...

An experiment is reported on the effects of cognitive similarity on proactive and retroactive interference (PI, RI) in short term memory. To avoid confounding between cognitive and acoustic similarity, the materials - i.e. words and digits - were matched with respect to vowel pattern. Effects of both PI and RI were found on recall of words,...
