This paper proposes a cognitive model of presence which emphasizes the interaction of top-down and bottom-up processes, and the subsequent creation of temporary representations of an environment in working memory. These temporary representations (which we term constructions) are formations of meaning about the environment, which allow a subject to make inferences and interact in that environmen...

The paper introduces a model that accounts for cognitive mechanisms of learning and generating multiple goal-directed actions. The model employs a novel idea of so-called the “sensory forward model” which is assumed to function in inferior parietal cortex for generation of skilled behaviors in humans and monkeys. A set of different goaldirected actions can be generated by the sensory forward mo...

Complex problem solving is often an integration of perceptual processing and deliberate planning. But what balances these two processes, and how do novices differ from experts? We investigate the interplay between these two in the game of SET. This article investigates how people combine bottom-up visual processes and top-down planning to succeed in this game. Using combinatorial and mixed-effe...

Der Beitrag behandelt psychologische Aspekte bei der Gestaltung und Evaluation sog. anthropomorpher Schnittstellen. Fokussiert werden dabei Ansätze zur Implementierung nonverbaler Verhaltenskomponenten. Unterschieden werden in diesem Zusammenhang modell-basierte top-down-Ansätze und datenbasierte bottom-up-Ansätze. Vorund Nachteile der beiden Zugehensweisen werden diskutiert und Integrationsmög...

Model-driven development of software-intensive systems aims at designing systems by stepwise model refinement. In order to create software product lines by model-driven development, product variability has to be represented on every modelling level and preserved under model refinement. In this paper, we propose ∆-modelling as an generally applicable variability modelling concept that is orthogo...

Biological visual attention has been long studied by experts in the field of cognitive psychology. The Holy Grail of this study is the exact modeling of the interaction between the visual sensory and the process of perception. It seems that there is an informal agreement on the four important functions of the attention process: (a) the bottom-up process, which is responsible for the saliency of...

This contribution proposes a compositionality architecture for visual object categorization, i.e., learning and recognizing multiple visual object classes in unsegmented, cluttered real-world scenes. We propose a sparse image representation based on localized feature histograms of salient regions. Category specific information is then aggregated by using relations from perceptual organization t...

Wird in einem Unternehmen die Entwicklung einer SOA geplant, so stellt sich schnell die Frage der richtigen Einführungsstrategie. Ist es sinnvoll, eine übergreifende Strategie zu fahren und ein allumfassendes Servicemodell als Ausgangspunkt festzulegen, um in einem Top-down-Ansatz die eigenen Produkte SOA-fähig zu machen? Oder sollen Investitionen in Legacy-Systeme geschützt werden, indem beste...

Deep generative models and their associated top-down architecture are gaining popularity in neuroscience and computer vision. In this paper we link our previous work with regulatory feedback networks to generative models. We show that generative model’s and regulatory feedback model’s equations can share the same fixed points. Thus, phenomena observed using regulatory feedback can also apply to...

This paper discusses the cognitive process (es) in recognizing instances of genre and the effects of generic features have on recognition of genre. Following the ESP tradition, the paper takes the communicative purpose as the defining feature of a genre and follow Martin’s stratified model of language and context in for the analysis. Based on a preliminary study conducted among three geologists...
