We shed new light on the long-debated question about the nature of mental images, that is, the underlying structures and processes, with a new theory of mental imagery. This theory is formalized as a computational cognitive model and provides an integrated account of the three prevalent theories of mental imagery, i.e., the descriptive, the quasi-pictorial, and the enactive theory. It does so b...

We present a cognitive process model of human sentence comprehension based on generalized left-corner parsing. A search heuristic based upon previouslyparsed corpora derives garden path effects, garden path paradoxes, and the local coherence effect.

Page’s proposal to stipulate representations in which individual units correspond to meaningful entities is too unconstrained to support effective theorizing. An approach combining general computational principles with domain-specific assumptions, in which learning is used to discover representations that are effective in solving tasks, provides more insight into why cognitive and neural system...

In order to respond quickly to changing market requirements, a business organisation needs to increase the level of agility in all phases of the business process engineering chain. Business process (BP) modelling is the first and most important phase in this chain. Designing a new and redesigning an existing process model is a highly complex, time consuming and error prone task. In this work, w...

This paper presents a cognitive model which describes the effect of a CIO’s transformational leadership on empowerment and leadership performance. The empirical literature on transformational leadership and empowerment demonstrates strong effects on leadership performance, but the literature has been limited to inquiries dealing with one of these issues. However, there have been little articles...

We present a novel way of accounting for similarity judgments. Our approach posits that similarity ratings stem from three main sources: familiarity, priming, and inherent perceptual similarity. We present a process model of our approach in the cognitive architecture ACT-R, and match our model’s predictions to data collected from a human subject experiment which involved simple perceptual stimu...

Current cognitive models of writing attribute the discovery of new ideas through writing to explicit problem-solving processes, and treat text production as a passive process of translating ideas into text. This paper describes an alternative, dual-process model of writing, in which text production is assumed to be an active knowledge-constituting process. A key prediction of the model is that ...

Times of crisis and prosperity may be the most defining moments of leadership and therefore one of the most important contexts in which to study leadership processes. In the present research we explored linguistic patterns of cognitive complexity, social representations and social coordination of Mao Zedong speeches during different socio-historical contexts, namely times of prosperity and cris...

In an effort to validate and demonstrate response and recovery sampling approaches and technologies, the U.S. Department of Homeland Security (DHS), along with several other agencies, have simulated a biothreat agent release within a facility at Idaho National Laboratory (INL) on two separate occasions in the fall of 2007 and the fall of 2008. Because these events constitute only two realizatio...
