Effects of Attention on Orientation-Tuning Functions of.. - McAdams, Maunsell (1999) (3 citations) (Correct)
....Motter, 1994a; Treue and Maunsell, 1996) These enhanced neural responses could account for the improved behavioral performance associated with attention. Attending to a particular object, location, or feature can improve detection thresholds and speed behavioral responses (Posner et al. 1980; Humphreys and Bruce, 1989; Rossi and Paradiso, 1995) Stronger neuronal responses typically have a better signal tonoise ratio (Schiller et al. 1976; Heggelund and Albus, 1978; Geisler and Albrecht, 1997) which might provide the basis for superior behavioral responses. It is possible, however, that changes in behavior ....

Seeing Things - Wilson, Knutsson (1994) (1 citation) (Correct)
....stored in my visual cortex, I have a symbol which represents a cup. Vision is therefore a process of inference, in which hypotheses about the state of the world are confirmed or rejected on the basis of evidence acquired visually. This is as true for machine vision as for biological vision (e.g. [1, 2, 9, 10, 11, 12]) Thus in a recent survey article [13] Rosenfeld elaborates the Marr paradigm in a way which brings out the inferential nature of the vision process ( a simplified version is given in Fig. 1) and makes the role of symbols clear. The unfortunate fact that the data upon which the inference is ....

A Common Framework for Kinetic Depth, Reconstruction and Motion.. - Sparr (1994) (3 citations) (Correct)
....point, relative the corresponding rate at the others. The vector Eff(X) will be called the depth flow at the point X, along the ray of sight. With terminology borrowed from psychophysics, the depth flow may be considered as a quantitative description of the kinetic depth effect, cf. e.g. [8]. Now put ff = ff(t 0 ) ff = ff(t 0 h) and let q = ff=ff. Then Eff q 1=h . In other words, apart from the power, the depth ratio q obtained from the algorithm above, gives an estimate of the strength of the depth flow. In [20] examples are given where the depth flow is computed, also with ....
