Inflation and Attention Thresholds

Contrast thresholds for component motion with full and poor attention.

We compare luminance-contrast-masking thresholds for fully and poorly attended stimuli, controlling attention with a demanding concurrent task. We use dynamic displays composed of discrete spatiotemporal wavelets, comparing three conditions ("single," "parallel," and "random"). In contrast to static displays, we do not find that attention modulates the "dipper" regime for masks of low luminance...

Oligopoly with Capacity Constraints and Thresholds

    Abstract   Extended Oligopoly models will be introduced and examined in which the firms might face capacity limits, thresholds for minimal and maximal moves, and antitrust thresholds in the case of partial cooperation. Similar situation occurs when there is an additional cost of output adjustment, which is discontinuous at zero due to set-up costs. In these cases the payoff functions of the...

The Relation Between Inflation and Inflation Uncertainty In Iran

Spatial vision thresholds in the near absence of attention

It is well known that attention increases the discriminability of some types of spatial information. To ascertain more specifically which types of spatial information benefit from attention, we have measured spatial vision thresholds both in the presence and in the near absence of attention. To obtain near absence of attention, we induce subjects to focus attention elsewhere in the display by m...

Thresholds and Expectation Thresholds

(See e.g. [2], [6] or [18]. Of course p0(n) is not quite unique, but following common practice we will often say “the” threshold when we should really say “a.”) It follows from [8] that every {Fn} has a threshold, and that in fact (see e.g. [18, Proposition 1.23 and Theorem 1.24]) p0(n) := pc(Fn) is a threshold for {Fn}. So the quantity pc conveniently captures threshold behavior, in particular...
