Psychologists often dismiss introspection as an inappropriate measure, yet subjects readily volunteer detailed descriptions of the time and effort that they spent on a task. Are such reports really so inaccurate? We asked subjects to perform a psychological refractory period experiment followed by extensive quantified introspection. On each trial, just after their objective responses, subjects ...

Psychological research has documented again and again marked performance decrements whenever humans perform 2 or more tasks at the same time. In fact, the available evidence seems to suggest that any type of behavior is subject to such limitations. The present experiments employed the psychological refractory period (PRP) paradigm to identify a clear exception to this rule: Unconditioned reflex...

The goal of the present experiment was to test the predictions of Central Bottleneck and Central Capacity Sharing models. According to the Central Bottleneck model, dual task interference, as observed in the PRP paradigm, is caused by an all-or-none bottleneck in information processing. The Central Capacity Sharing model postulates that dual task interference is caused by a capacity limited pro...

We construct embedded closed minimal surfaces in the round three-sphere S(1), resembling two parallel copies of the Clifford torus, joined by m small catenoidal bridges symmetrically arranged along a square lattice of points on the torus.

Identifying the precise locus of general cognitive ability (g) in the flow of information between perception and action is an important goal of differential psychology. To localize the negative correlation between g and reaction time to a specific processing stage, we administered a speeded number-comparison task to two groups differing in average g. The participants had to respond to two stimu...

For distributed arithmetic the latency is proportional to the maximal number of fractional bits for any coefficient. When implementing recursive filters this is a disadvantage as the resulting minimal sample period may be longer compared with an implementation using separate multiplications and additions. In this paper we propose a method to decrease the latency for inputs where the correspondi...

excessive daytime sleepiness, cataplexy, sleep paralysis, and hypnagogic hallucinations (1). A nocturnal polysomnogram, followed by the multiple sleep latency test is suggested for the diagnosis. These tests, performed at a sleep disorders clinic, confirm the daytime sleepiness by showing a short sleep latency of usually less than 5 minutes, as well as an abnormally short latency prior to the f...

PURPOSE Synthetic progestins are widely used therapeutically; however, there is controversy regarding their proliferative effects. We used a rat 7,12-dimethylbenz[a]anthracene (DMBA)-induced mammary tumor model to test the hypothesis that progestins increase angiogenesis and as a result decrease the latency period and increase the multiplicity of mammary tumors. EXPERIMENTAL DESIGN Medroxypro...

Latency is the time delay between an exchange streaming market data to a trader, trader processing information and deciding trade, receiving order from trader. Liquidity takers face moving target problem as consequence of their latency in marketplace. They send orders with limit price that aim at quantity they observed book (LOB), by processed exchange, prices could have worsened, so may not be...

We construct quasiconformal mappings in Euclidean spaces by integration of a discontinuous kernel against doubling measures with suitable decay. The differentials of mappings that arise in this way satisfy an isotropic form of the doubling condition. We prove that this isotropic doubling condition is satisfied by the distance functions of certain fractal sets. Finally, we construct an isotropic...
