Interviews with ethnic interviewees: Non-verbal communication errors in impression formation

Two studies are described concerning ethnic interviewees in interviews. The first study (a style of presentation study) revealed several differences in non-verbal behaviour displayed by Dutch and ethnic interviewees in interviews. The second study showed that interviewees with an ‘ethnic style’ of non-verbal presentation were assessed more negatively than interviewees with a ‘Dutch style’ of non-verbal presentation by a Dutch selection board. Finally, some implications of the results are discussed.     

The Effects of Street Noise and Field Independency on Police Officers' Shooting Behavior

Two studies examining the effects of street noise on police officers' emotion, perception, and performance in simulated shooting events are discussed. Compared to previous research, our studies had a higher ecological validity. In our studies, "relevant" noise was introduced, the subjects were police officers instead of students, and the behavior we examined was police behavior in simulated firearms incidents. Results revealed that noise resulted in increased emotion, a narrowed perception, and an impairment in performance on secondary tasks. In Study 2, the effects of field independency on emotion, perception, and performance were examined. The outcomes showed that high field-independent subjects compared to low field independent subjects obtained better results regarding perception and performance. Finally, some implications are discussed.     

RACE/A: an architectural account of the interactions between learning, task control, and retrieval dynamics

This article discusses how sequential sampling models can be integrated in a cognitive architecture. The new theory Retrieval by Accumulating Evidence in an Architecture (RACE/A) combines the level of detail typically provided by sequential sampling models with the level of task complexity typically provided by cognitive architectures. We will use RACE/A to model data from two variants of a picture-word interference task in a psychological refractory period design. These models will demonstrate how RACE/A enables interactions between sequential sampling and long-term declarative learning, and between sequential sampling and task control. In a traditional sequential sampling model, the onset of the process within the task is unclear, as is the number of sampling processes. RACE/A provides a theoretical basis for estimating the onset of sequential sampling processes during task execution and allows for easy modeling of multiple sequential sampling processes within a task.     

The art of imitation: Wilhelm Stekel's Lehrjahre

In the early history of psychoanalysis, the work of Wilhelm Stekel (1868-1940) was by and large neglected, even though he wrote a considerable number of psychoanalytic studies, some of which should be considered to have had a major influence on Freud's early thought. Freud, in turn, had much greater influence on Stekel than is commonly believed. In this article, the authors aim to uncover some of these mutual influences, in particular in the field of practice, by focusing on the elements of autobiography and self-analysis. The authors have identified a number of covert autobiographical passages in the work of Stekel, and attempt to link one of these 'revelations' to an equally covert response to it by Freud. In the closing section of this article, the authors argue that Stekel's attempt to imitate Freud's self-analysis contributed to the fracture between the two of them.     

Substantive and procedural norms in normative multiagent systems

Procedural norms are instrumental norms addressed to agents playing a role in the normative system, for example to motivate these role playing agents to recognize violations or to apply sanctions. Procedural norms have first been discussed in law, where they address legal practitioners such as legislators, lawyers and policemen, but they are discussed now too in normative multiagent systems to motivate software agents. Procedural norms aim to achieve the social order specified using regulative norms like obligations and permissions, and constitutive norms like counts-as obligations. In this paper we formalize procedural, regulative and constitutive norms using input/output logic enriched with an agent ontology and an abstraction hierarchy. We show how our formalization explains Castelfranchi's notion of mutual empowerment, stating that not only the agents playing a role in a normative system are empowered by the normative system, but the normative system itself is also empowered by the agents playing a role in it. In our terminology, the agents are not only institutionally empowered, but they are also delegated normative goals from the system. Together, institutional empowerment and normative goal delegation constitute a mechanism which we call delegation of power, where agents acting on behalf of the normative system become in charge of recognizing which institutional facts follow from brute facts.     

Meta-Argumentation Modelling I: Methodology and Techniques

In this paper, we introduce the methodology and techniques of meta-argumentation to model argumentation. The methodology of meta-argumentation instantiates Dung’s abstract argumentation theory with an extended argumentation theory, and is thus based on a combination of the methodology of instantiating abstract arguments, and the methodology of extending Dung’s basic argumentation frameworks with other relations among abstract arguments. The technique of meta-argumentation applies Dung’s theory of abstract argumentation to itself, by instantiating Dung’s abstract arguments with meta-arguments using a technique called flattening. We characterize the domain of instantiation using a representation technique based on soundness and completeness. Finally, we distinguish among various instantiations using the technique of specification languages.

Permission from an Input/Output Perspective

Input/output logics are abstract structures designed to represent conditional obligations and goals. In this paper we use them to study conditional permission. This perspective provides a clear separation of the familiar notion of negative permission from the more elusive one of positive permission. Moreover, it reveals that there are at least two kinds of positive permission. Although indistinguishable in the unconditional case, they are quite different in conditional contexts. One of them, which we call static positive permission, guides the citizen and law enforcement authorities in the assessment of specific actions under current norms, and it behaves like a weakened obligation. Another, which we call dynamic positive permission, guides the legislator. It describes the limits on the prohibitions that may be introduced into a code, and under suitable conditions behaves like a strengthened negative permission.     

Stroop and picture—word interference are two sides of the same coin

This article presents a cognitive model that reconciles a surprising observation in the picture—word interference (PWI) paradigm with the general notion that PWI is a form of Stroop interference. Dell’Acqua, Job, Peressotti, and Pascali (2007) assessed PWI using a psychological refractory period (PRP) paradigm, and concluded that the locus of interference in PWI is during the perceptual encoding stage. Stroop interference, on the other hand, is generally attributed to response selection. Based on these findings it was argued that PWI is not a Stroop effect. The present article discusses an alternative interpretation of these results. We assume that both effects are caused by the same interference mechanism, but that the processing speed associated with the different stimuli (colors vs. words) accounts for the previously reported differences. We support this argument by presenting a single computational model that accounts for both PWI and Stroop phenomena in single task and PRP settings.
