In this paper, we outline the approach we have developed to construct an emotion-recognising system. It is based on guidance from psychological studies of emotion, as well as from the nature of emotion in its interaction with attention. A neural network architecture is constructed to be able to handle the fusion of different modalities (facial features,(More)
We investigate, by constructing suitable models, the manner in which attention and executive function are observed to interact, including some aspects of the influence of value/emotion on this interaction. Attention is modelled using the recent engineering control model (Corollary Discharge of Attention Movement, CODAM), which includes suitable working(More)
We review a recently developed engineering control approach to attention. The control system is extended to include biasing by emotional valence, with qualitative analysis given of a range of emotion paradigms. Application of the model is made to a recent paradigm underlining the need for attention in emotional influences. The paper ends with conclusion and(More)
There is presently an ongoing debate about the relation between attention and consciousness. Thus debate is being fuelled by results from experimental paradigms which probe various forms of the interaction between attention and consciousness, such as the attentional blink, object-substitution masking and change blindness. We present here simulations of(More)
Links between attention and emotion were investigated by obtaining electrophysiological measures of attentional selectivity together with behavioral measures of affective evaluation. Participants were asked to rate faces that had just been presented as targets or distractors in a visual search task. Distractors were rated as less trustworthy than targets.(More)
