data have generated valuable results on crime and place, but have at least two limitations. Firstly, the importance of environmental characteristics in generating spatio-temporal crime patterns calls into question the generalizability of studies conducted in a single setting. For example, Los Angeles

multipliers. RESULTS Variography The analysis of the survey ’ s data always allowed to describe the spatial or the spatio-temporal structure of the variable “ abundance index ” , also when a secondary variable, like depth, was considered. In Ž g. 1 the auto-variogram model of the abundance index (kg/km 2 ) of

duration is expressed through distance notions, but not the reverse, showing that space and time are asymmetrically dependent on each other ( Casasanto & Boroditsky, 2008 ). To what extent these are bound together, in terms of learning and adaptation to spatio-temporal changes, is not yet clear. Skinner

Each data point represents the mean of four measured thresholds by a two-interleaved-staircase method. Each function shows different types of spatio-temporal modulation; the first, the second and the

model for static vision (Young, 1978, 1985a, b, c, d, 1986a, b, 1987, 1989, 1991). We then compare the new GD spatio-temporal model with other models of receptive Ž elds in visual cortex. The results of Ž tting receptive Ž eld data with the model, and of a machine implementation, are discussed in the

discussed below, the in- terpretation of our data is constrained by the assumption that the spatio-temporal separations used here are within the integration area of a motion sensitive receptive field. Alternatives to the standard view essentially consist in relating SSV tasks to (or 'translating' them into

Derivative (GD) model for spatio-temporal vision. All 23 Ž elds in the data sample could be Ž t by one equation, varying only a single shape number and nine geometric transformation parameters. A difference-of-offset-Gaussians (DOOG) mechanism for the GD model also Ž t the data well. Other models tested did
