Article
Full-text available
Autonomous agents (AA) will increasingly be deployed as teammates instead of tools. In many operational situations, flawless performance from AA cannot be guaranteed. This may lead to a breach in the human’s trust, which can compromise collaboration. This highlights the importance of thinking about how to deal with error and trust violations when d...

The role of intelligent agents becomes more social as they are expected to act in direct interaction, involvement and/or interdependency with humans and other artificial entities, as in Human-Agent Teams (HAT). The highly interdependent and dynamic nature of teamwork demands correctly calibrated trust among team members. Trust violations are an ine...
Article
Full-text available
Citizens are increasingly expected to take a more participatory role in society, which increases the need for them to be knowledgeable about a wide range of uncertain risks and to properly prepare themselves in case these risks become reality. To date, most attention regarding risk preparedness has focused on natural hazards. In the past decade, ho...

Given their different views and interests, how do liaisons in interorganizational crisis response teams negotiate collective decisions? We conducted an experiment with eight crisis response teams to answer this question. Taking a bureau-political view, we find that liaisons make decisions by following one of two decision-making pathways. First, lia...
Article
Full-text available
Decision-making during a crisis is affected by several sources of information and prior knowledge, such as factual (statistical) information, narratives of others, and real-time governmental messages. The present study investigated how two types of information (statistics and narratives) influence helping behavior after the occurrence of a traffic...
Article
Full-text available
Although there is a large potential of citizen capital in fighting crime and creating safer neighborhoods, in reality, only a small fraction of citizens is actively participating. This study examines the relationship between different types of actual participation behavior in the police domain from a citizen's stance and 3 different but interconnec...

Article
Worldwide there is a growing need for citizens to prepare for environmental risks to mitigate potential adversity. In order to predict preparedness, behavioral models typically used variables at an individual level of analysis, such as risk perception and assessment of the effectiveness of possible actions (response-efficacy). The present study ela...
Article
This study aimed to gain insight into the (combined) effects of risk and crisis communication on adequate behaviour during a crisis situation. In addition, it adds to the existing literature by examining the effects of risk and crisis communication on psychological factors that are involved in decision-making during a crisis. This study, utilizing...

The myth that citizens are completely helpless during incidents and have no other role than that of victim has been exploded. People do help themselves, each other and the emergency services during incidents. The training of emergency service workers still predominantly focuses on processes and the application of professional expertise, with little...
Article
Full-text available
Incident evaluations show that bystanders tend to help: they do not wait for professionals to arrive, but act as required by the situation at hand. In the present study, we investigated how safety awareness (induced before an accident happened) and providing a course of action by emergency services affect helping behavior after witnessing a virtual...
Article
The goal of the present study was to investigate whether playing a serious game concerning natural and man-made risks leads to increased risk awareness and additional information search. As an experimental task, we developed a serious board game. Fifty-six students participated in the experiment; half of them played the serious game whereas the oth...
Article
Full-text available
In neurocognitive research on language, the processing principles of the system at hand are usually assumed to be relatively invariant. However, research on attention, memory, decision-making, and social judgment has shown that mood can substantially modulate how the brain processes information. For example, in a bad mood, people typically have a n...
Article
An important decision that terminally ill patients may face is where they want to spend the last period of their lives. To support patients in making this choice, a decision aid was developed. In the present study, we investigated whether participants could better withstand opinions against their favored option when they had consulted this decision...
Article
Full-text available
Decisions and judgments made after deliberation can differ from expert opinion and be more regretted over time than intuitive judgments and decisions. We investigated a possible underlying process of this phenomenon, namely global versus local processing style. We argue that deliberation induces a local processing style. This processing style narro...
Article
Most terminally ill patients prefer to die at home rather than at an institution. However, patients are often insufficiently aware of the downsides of staying at home, which signals a need for effective decision aids. The main purpose of the present study was to compare indirect methods of value elicitation (personal narratives["stories"] in text o...
Article
A main threat to objective information processing in crime investigation teams is the tendency to focus on one particular interpretation only. To prevent such tunnel vision or ‘groupthink’, an investigation team can call in a crime analyst, and ask him or her to give a fresh and independent account of the evidence at hand. However, before they exam...
Article
Even though trace evidence is becoming more and more important in legal cases, only little is known about the influence of task and context factors on comparative judgments. In the present study we investigated how expectations and complexity affect shoe print examinations and to what extent differences exist between beginners and experienced exami...
Article
Analysts base their hypotheses concerning terrorist groups and terrorist attacks generally on large amounts of information, which may be uncertain, inconsistent and/or incomplete. The present paper addresses the questions of how an analyst constructs a causal scenario, which biases occur and how this intelligence process can be supported. In the fi...
Article
An experiment was conducted to investigate the effects of accent, telephone and a relatively long retention interval (3 or 8 weeks) on speaker identification. Three-hundred and sixty participants heard the target's voice and were asked to identify the target by means of a line-up consisting of 6 voices. Half of the participants were given a target-...
Article
To what extent response mode and experience affect the assessment of disability was investigated. An experiment was conducted in which 34 medical doctors (17 inexperienced and 15 experienced) were required to assess disability of a videotaped client. Participants either gave a probability assessment after each piece of information or only after all...
Article
An experiment was conducted in which the effectiveness of three line-up methods (live, video, and photographs) was compared. Participants witnessed a staged event and were subsequently required, by one of the three methods, to identify the target. Both target-present and target-absent line-ups were used. The results showed that all methods led to a...
Article
An experiment was conducted to investigate the reliability of voice lineups. More specifically, the experiment was designed to look into the effects of retention interval (an immediate test or after a week), speech duration (30 or 70 s) and acoustic environment (indoors or indoors and outdoors) on speaker identification accuracy. In addition, the r...
Article
Automation has changed the role of human operators from direct manual control to supervision. Their main task is to monitor whether system performance remains within pre-specified ranges and intervention is only required in unusual situations. One of the consequences is a loss of situation awareness, which significantly affects performance in abnor...
Article
An experiment was conducted to investigate both the effect of the order of presentation of defence and prosecution evidence and the prior availability of background information on assessment of guilt. Subjects were required to judge the defendant's probability of guilt either after each witness statement (step-by-step) or after having read all witn...

Article
Previous research on dynamic decision behaviour consistently indicated that individuals tend to use a judgment-oriented strategy. When faced with deteriorating system performance people prefer to select information before they apply an action, even when the straightforward application of actions would result in better task performance. In the prese...
Article
In the present study we investigated how monitoring and fault management in a ship control task are affected by complexity and a priori probability of disturbances. Participants were required to supervise four independent shipping subsystems and to adjust the subsystems whenever deviations occurred. However, in order to apply the correct action, th...
Article
An experiment was conducted to investigate the effect of a priori probability of false alarms and time pressure on decision-making behaviour in a dynamic task environment. In order to assess whether strategy selection in a dynamic task environment would be adaptive, we modelled the task mathematically, and compared actual decision strategies to the...
Article
Decision-making behaviour is considerably affected by dynamic aspects of the task environment. First of all, as a dynamic situation continuously changes, a decision maker has to take time into consideration. Second, a decision maker can use feedback providing information on the effect of own actions on system change, elaborating the set of strategi...
Article
Previous research on strategy selection in dynamic task environments indicated that subjects preferred to request information first, before an action was applied, even when the straightforward application of actions would have resulted in more optimal performance. Furthermore, this strategy was also used when subjects only had limited time for diag...
Article
Decision making research shows an increasing interest for time- dependent decisions. In contrast with decision making in static tasks, where, based on the available information, only one decision needs to be made, dynamic environments offer the possibility to adjust incorrect decisions through continuous feedback on the overall system state. It is...
Article
Information processing in dynamic situations can be distinguished on a number of dimensions from decision making in the normally used static task environments. First, because the environment changes, time is an inherent dimension of the decision making process. Second, strategies can be used that benefit from feedback. Third, time pressure can be d...
Article
To date, research has mainly used deadlines in static task environments to investigate the effects of time pressure on decision making behavior. A dynamic environment, on the other hand, changes over time and time pressure may result when time is not used efficiently and negative consequences are rapidly increasing. An experiment was carried out to...
Article
Previous research has consistently shown that subjects switch to noncompensatory information search behaviour when task complexity increases. However, a rather specific class of tasks was used in these studies for which complete information search is not necessary to attain accurate task performance. In the present study information search behaviou...
Article
In this experiment we investigated the influence of expectation, exposure time and jacket hood positioning on person identification. Thirty subjects, all employees of the TNO Institute for Perception, participated in the experiment. They were presented with slides showing known and unknown persons who were photographed under bad lighting conditions...
Article
Two experiments were conducted to investigate time pressure effects on both the selected decision strategy and the quality of task performance. A dynamic task environment was used. Subjects were required to monitor the continuously changing fitness level of an athlete, and to recover the athlete whenever fitness decline had a physiological cause. T...
Article
In this experiment the hypothesis was tested that changing information search patterns, that are observed when task complexity increases, can be explained by an adaptive response to the choice environment. Two factors were manipulated: Task complexity (number of alternatives and number of dimensions) and type of task (a multidimensional task requir...
Article
The present experiment investigates time pressure effects on both the quality of task performance and the underlying cognitive processes. The task that was used is dynamic in nature, such that the environment changes over time both autonomically and as a result of actions taken by the decision maker. Twenty subjects were required to monitor the fit...
Article
Structural modelling research and studies using information boards have reported contradicting findings regarding the cognitive processes underlying individual decision making. Whereas in the structural modelling approach choices could well be predicted by linear models, information board studies have stressed the nonlinear use of information as a...
Article
Judgement tasks require knowledge of relations between symptoms (cues) and diagnosis. These relations are often probabilistic in nature, and decisions therefore have to be based on more or less unreliable cues. Many so- called Multiple Cue Probability Learning (MCPL) studies have shown that learning such relations is seriously impaired, even by a s...

Optimal collaboration between humans and autonomous systems requires that the level of trust the user has is warranted by the system’s capabilities (J.D. Lee & See, 2004). It relies heavily on the system’s capacity to effectively communicate with the user, i.e., to explain why a violation has occurred, so as to remedy damaged trust. This project therefore focuses on the psychosocial requirements for the maintenance and repair of trust in human-agent teaming.
