The potential of the buildup and release from proactive interference (PI) technique in the study of animal categorization was demonstrated with a rhesus monkey. A serial probe recognition task was used with a list of 4 consecutive slide pictures (upper screen) followed by a single probe picture (lower screen). The monkey moved a lever to indicate whether or not the probe was contained in the li...

The aim of this paper is to define a non-ambiguous operational semantics for event-based multi-agent modeling and simulation, applied to complex systems. A number of features common to most multi-agent systems have been retained: 1) agent proactive as well as reactive behavior, 2) concurrency : events can arrive simultaneously to an agent, an environment or any simulated entity and the actual c...

In this demonstration, we bring the online selling process closer to the customer experience in a retailing store. For this purpose, we demonstrate a virtual selling agent that is proactive and adaptive. Our proactive dialogical agent initiates the dialogue and drives the inquiring process for collecting information in order to make relevant proposals. Moreover, we will see that our virtual sel...

Proactive control allows us to maneuver a changing environment and individuals are distinct in how they anticipate and approach such changes. Here, we examined how individual differences in personality traits influence cerebral responses to conflict anticipation, a critical process of proactive control. We explored this issue in an fMRI study of the stop signal task, in which the probability of...

Processing irrelevant visual information sometimes activates incorrect response impulses. The engagement of cognitive control mechanisms to suppress these impulses and make proactive adjustments to reduce the future impact of incorrect impulses may rely on the integrity of frontal-basal ganglia circuitry. Using a Simon task, we investigated the effects of basal ganglia dysfunction produced by P...

Despite numerous improvements in the development and maintenance of software, bugs and security holes exist in today’s products, and malicious intrusions happen frequently. While this is a general problem, it explicitly applies to webbased services. However, Byzantine fault-tolerant (BFT) replication and proactive recovery offer a powerful combination to tolerate and overcome these kinds of fau...

There has recently been a resurgence in the idea that amnesia may be characterized by an increased susceptibility to interference. In the present study we tested this idea using a well-controlled and well-established animal model of amnesia: impairment in object recognition following perirhinal and postrhinal cortical (PPRh) damage. We used this paradigm to test whether memory impairment was ex...

BACKGROUND Working memory (WM) performance is often decreased in older adults. Despite the growing popularity of WM trainings, underlying mechanisms are still poorly understood. Resistance to proactive interference (PI) constitutes a candidate process that contributes to WM performance and might influence training or transfer effects. Here, we investigated whether PI resistance can be enhanced ...

There is no consensus as to why forgetting occurs in short-term memory tasks. In past work, we have shown that forgetting occurs with the passage of time, but there are 2 classes of theories that can explain this effect. In the present work, we investigate the reason for time-based forgetting by contrasting the predictions of temporal distinctiveness and trace decay in the procedure in which we...
