Can a decay process explain the timing of conditioned responses?
نویسنده
چکیده
To explain time-scale invariant distributions of response latencies, it appears to be necessary to postulate scalar noise in the remembered intervals, against which the subjective measure of the currently elapsing interval is compared. At least in some cases, the observed variability cannot be due to variability in the subjective intervals written to memory; it must come from noise (variability) in the reading of a memory. The Staddon and Higa proposal offers no explanation for the observed variability, and it is unclear what noise assumption would yield the observed variability, given their assumption that intervals are timed by a nonlinear decay process. The decay process cannot plausibly be represented by the logarithmic function, because it begins and ends at infinity. The assumption of any form of nonlinear timing is inconsistent with the most important result of the time-left experiment, which is that the changeover time increases linearly with the comparison-standard difference.

Comment on "Cerebellar LTD and learning-dependent timing of conditioned eyelid responses".
Mammals can be trained to make a conditioned movement at a precise time, which is correlated to the interval between the conditioned stimulus and unconditioned stimulus during the learning. This learning-dependent timing has been shown to depend on an intact cerebellar cortex, but which cellular process is responsible for this form of learning remains to be demonstrated. Here, we show that prot...

Background: Nowadays, dendritic cells (DC) are used for tumor immunotherapy as they can induce immune responses against tumor cells. In this research, we comprehensively studied the maturation stimulus addition, PHA-activated T-cell (PHA- TCM) conditioned medium, autologous monocyte-conditioned medium (MCM) and TNF-α for their ability to promote uniformly mature dendritic cells that eli...
متن کاملStrongly stable multi-time stepping method with the option of controlling amplitude decay in responses
Recently, multi-time stepping methods have become very popular among scientist due to their high stability in problems with critical conditions. One important shortcoming of these methods backs to their high amount of uncontrolled amplitude decay. This study proposes a new multi-time stepping method in which the time step is split into two sub-steps. The first sub-step is solved using the well-...

The purpose of this paper is to examine the determinants of the timing of bank failure/merger in 10 Asian countries over the period of 1999-2007 using a multivariate logit model and a split population duration analysis. Apart from bank-specific information, we also focus on the effects of macroeconomic and financial characteristics. The following empirical findings are obtained. First, the resu...
