Modeling and designing systems that require a high level of coordination, control and automation is a very difficult task. The problem is the lack of design processes able to cover all the features these systems present. This paper presents an extension of the ASPECS metamodel for supporting organizational and normative principles and it allows to define models not only from an holonic agent vi...

The Stroop Test is a quick and frequently used measure in screening for brain damage, dysfunction of selective attention, and cognitive flexibility. The purpose of the present study is to provide normative data for Trenerry's Stroop Neuropsychological Screening Test (SNST) in a sample of 605 healthy Greek participants (age range: 18-84 years, education range: 6-18 years). Results revealed that ...

UNLABELLED The P300 component of the event-related potential (ERP) is a general measurement of "cognitive efficiency". It is an index of the ability of an individual's central nervous system (CNS) to process incoming information. OBJECTIVE To compare the neuromodulatory effects of caffeine and bromazepam on the visual ERP (P300), in relation to a P300 normative database. METHOD 15 right-han...

Behavioral and neural evidence reveal a prospective goal-directed decision process that relies on mental simulation of the environment, and a retrospective habitual process that caches returns previously garnered from available choices. Artificial systems combine the two by simulating the environment up to some depth and then exploiting habitual values as proxies for consequences that may arise...

Why are people's judgments incoherent under probability formats? Research in an associative learning paradigm suggests that after structured learning participants give judgments based on predictiveness rather than normative probability. This is because people's learning mechanisms attune to statistical contingencies in the environment, and they use these learned associations as a basis for subs...

In an environment full of potential goals, how does the brain determine which movement to execute? Existing theories posit that the motor system prepares for all potential goals by generating several motor plans in parallel. One major line of evidence for such theories is that presenting two competing goals often results in a movement intermediate between them. These intermediate movements are ...

The paper explores the idea that causality-based probability judgments are determined by two competing drives: one towards veridicality and one towards effort reduction. Participants were taught the causal structure of novel categories and asked to make predictive and diagnostic probability judgments about the features of category exemplars. We found that participants violated the predictions o...

A vast literature shows that individuals frequently violate normative principles in reasoning. In evaluating the relevance of these findings for psychology, economics, and related disciplines, it is natural to ask whether reasoning errors reflect random aberrations or systematic biases. One straightforward way to approach this question is to test their persistence at the aggregate level. In thi...

The present study provides normative data from a sample of 257 healthy children and 608 adults on a modified version of the Five-Point Test (5PT). The 5PT is a structured and standardized test measuring figural fluency functions. Interrater reliability, test-retest-reliability and construct validity of this measure were analyzed. The sensitivity of the task for cognitive disturbances of patient...

The idea of agroecosystem analysis has at least some roots in the frustration of researchers who saw their technological innovations too often ignored by farmers (Conway 1985;1986;1987). This led to a “systems” approach manifested in a variety of ways, but generally with a strong measure of farmer participation. The “Conway school” and most other systematic approaches to analyzing agroecosystem...
