What we pay attention to is influenced by both reward learning and aversive conditioning. Although early attention tends to be biased toward aversively conditioned stimuli, sustained ignoring of such stimuli is also possible. How aversive conditioning influences how a person chooses to search, or the strategic control of attention, has not been explored. In the present study, participants learned an association between a colour and an aversive outcome during a training phase, and in a subsequent test phase searched for one (...) of two targets presented on each trial; one target was rendered in the aversively conditioned colour (CS+) and the other in a neutral colour (CS-). Given the distribution of colour stimuli in the search array, it was more optimal to search for and report a target in one of the two colours on some trials. Our results demonstrate that participants were biased away from the CS+ target, which resulted in non-optimal search on some trials. Surprisingly, rather than accentuate this bias, greater state anxiety was associated with a stronger tendency to find and report the CS+ target. Our findings have implications for our understanding of the learning-dependent control of attention and abnormal attentional biases observed in high-anxious individuals. (shrink)

Desktop computerisation is a widespread phenomenon that affects many women office workers. So far, much of the discussion of this topic treats these workers as ‘users’ while the need for them to (re)design their work and information systems tends to be ignored.This paper applies both conventional and social analytic notions of information systems design to archetypal secretarial work groups, and argues that hitherto under-recognised elements of system design are endemic to desktop computerisation. Case studies which examine how office groups have (...) created information systems and associated work practices, largely through their own efforts, illustrate how this design work can be accomplished. The informal, localised processes of collaborative problem solving, development and sharing of local expertise are important ingredients in this achievement. Broader mobilisation efforts can also play a role. (shrink)
