Please cite this article in press as: Clay, Z., et Behaviour (2012), doi:10.1016/j.anbehav.201 Alarm calls and food-associated calls from a diverse range of species are said to be functionally referential, in that receivers can use these sounds to predict environmental events in the absence of other contextual cues. The evolutionary driver for referential alarm calls has been hypothesized to be...

One of the core components of language is referring, which requires the speaker to choose between expressions that are highly explicit (e.g., the UNC professor, or Peter), and reduced lexical forms (e.g., he). This paper reviews claims that this process is largely driven by the accessibility or salience of the referent, and the psychological processes that underlie these effects. Two classes of...

REFERENTIAL GROUNDING TOWARDS MEDIATING SHARED PERCEPTUAL BASIS IN SITUATED DIALOGUE

This study used positron emission tomography (PET) to identify the brain substrate of self-referential reflective activity and to investigate its relationship with brain areas that are active during the resting state. Thirteen healthy volunteers performed reflective tasks pertaining to three different matters (the self, another person, and social issues) while they were scanned. Rest scans were...

Wójcicki has provided a characterization of selfextensional logics as those that can be endowed with a complete local referential semantics. His result was extended by Jansana and Palmigiano, who developed a duality between the category of reduced congruential atlases and that of reduced referential algebras over a fixed similarity type. This duality restricts to one between reduced atlas model...

Cognitive behavioral therapy (CBT), an effective treatment for depression, targets self-referential processing of emotional stimuli. We examined the effects of CBT on brain functioning during self-referential processing in depressive patients using functional magnetic resonance imaging (fMRI). Depressive patients (n = 23) and healthy participants (n = 15) underwent fMRI scans during a self-refe...

A data warehouse integrates tables coming from multiple source databases, where each database has different tables, columns with similar content across databases and different referential integrity constraints, enforced to different compliance levels. Some source databases may have more reliable data than others, if referential integrity is more strictly enforced or their respective logical dat...

This doctoral thesis investigates how a robot companion can gain a certain degree of situational awareness through observation and interaction with its surroundings. The focus lies on the representation of the spatial knowledge gathered constantly over time in an indoor environment. However, from the background of research on an interactive service robot, methods for deployment in inference and...

Referential integrity is an essential global constraint in a relational database, that maintains it in a complete and consistent state. In this work, we assume the database may violate referential integrity and relations may be denormalized. We propose a set of quality metrics, defined at four granularity levels: database, relation, attribute and value, that measure referential completeness and...
