Sensory/perceptual ability

Laboratory studies in which subjects smoked marijuana have documented that marijuana impaired sensory-perceptual abilities by reducing CFF threshold and by increasing the subjective... 

The following sections examine two processes associated with recmitment activities (i.e., job analysis, and realistic safety preview), and a range of selection predictors (application blank, applicant interview, cogiutive, physical, psychomotor, sensory/perceptual ability testing, personality testing, and attitude measurement) which an organization can use to help predict job applicant (new employee s) safety behavior, and overall their ability to work safely. Where appropriate, recommendations on how recruitment and selection processes can be used to improve new employee safety are discussed. Finally, this chapter examines how employees perceptions of organizational processes can be made more realistic. 

A large number of volatile chemicals, [many from essential oils and present at low concentration], interacting with the olfactory receptors are essential for the full impact and character of a fhvor. The appeal of wines and of foods critically depends upon this complexity, which expresses the ability of the flavorist to appeal optimally to the individual s sensory and perceptual abilities. 

It has been shown quite clearly that children s sensory preferences may differ from those of adults (e.g., Zandstra and de Graaf, 1998), and that growing from childhood into adulthood may alter preferences, in particular for sweet tastes (Desor and Beauchamp, 1987). Children s sensory perceptions may also differ from those of adults, especially when intensity scaling is used (Zandstra and de Graaf, 1998), and to a lesser extent when pair comparisons are used (MenneUa et al., 2003). However, the extent of differences in terms of perceptions between children and adults, or between children from various age groups, is often inferred from hedonic judgements, making a true comparison of children s and adults sensory abilities difficult. One cannot rule out the possibility that children differ more from adults in terms of affective responses than of perceptual abilities. 

In the first trial, information shared was limited to robot position, while in the second trial robots were used as virtual sensors, as proposed in Gasparri, Panzieri, and Pascucci (2008). In this case, the robot sensory system is augmented by the perceptual ability of its neighbors. As a consequence, the estimate error is considerably reduced, since more information is used to form the belief. A drawback of this approach is the communication cost since a large amoimt of information needs to be shared.
