Wernicke suggested that semantic knowledge arises from the interaction of modality-specific perceptual representations of objects, and of the words used to describe them. We present a computational implementation of this theory, in which semantic representations arise from learning mechanisms that acquire the mappings between visual representations of objects and their verbal descriptions. To t...

Recalling an event at 1 time often increases the likelihood that it will be remembered at a still later time. The authors examined the degree to which older and younger adults' memory for everyday events that they watched on a videotape was improved by later seeing photographs or reading brief verbal descriptions of those events. Both older and younger adults recalled more events, in greater de...

This paper presents the construction of a HPSG lexicon of Arabic verbal entities, automatically inferred from the Arabic VerbNet, a large coverage verb lexicon where verbs are classified using syntactic alternations. We discuss the main verb specification along with the relation of the syntactic and semantic levels of representation within the HPSG framework. Extensive analysis of the Arabic Ve...

Wernicke (1900, as cited in G. H. Eggert, 1977) suggested that semantic knowledge arises from the interaction of perceptual representations of objects and words. The authors present a parallel distributed processing implementation of this theory, in which semantic representations emerge from mechanisms that acquire the mappings between visual representations of objects and their verbal descript...

The modeling of a landscape environment is a cognitive activity that requires appropriate spatial representations. The research presented in this paper introduces a structural and semantic categorization of a landscape view based on panoramic photographs that act as a substitute of a given natural environment. Verbal descriptions of a landscape scene provide the modeling input of our approach. ...

Bar graphs and line graphs are commonly used ways of graphical communication. Due to the difference in their perceptual visuo-spatial properties, they facilitate comprehension of different events. Bar graphs are commonly used in the domain of precipitation although the data intrinsically carry information that is averaged over long time spans. In this study, we investigate how the presence of i...

Visual search is controlled by representations of target objects (attentional templates). Such templates are often activated in response to verbal descriptions of search targets, but it is unclear whether search can be guided effectively by such verbal cues. We measured ERPs to track the activation of attentional templates for new target objects defined by word cues. On each trial run, a word c...

Tactile maps offer access to spatial-analog information for visually impaired people. In contrast to visual maps, a tactile map has a lower resolution and can only be inspected in a sequential way, complicating the extraction of spatial relations among distant map entities. Verbal assistance can help to overcome these difficulties by substituting textual labels with verbal descriptions and offe...

In communication settings, statistical graphs accompany language by providing visual access to various aspects of domain entities, such as conveying information about trends. A similar and comparable means for providing perceptual access is to provide haptic graphs for blind people. In this study, we present the results of an experimental study that aimed to investigate visual line graphs and h...
