This paper is an empirical examination of observational learning. Using data from an online market for music, I find that observational learning is a valuable tool for the producers of high quality products and for consumers, but not necessarily for the online platform. I also study the role of pricing as a friction to the learning process by comparing outcomes under a demand based pricing sche...

We present a theory of environmental bisimilarity for the delimited-control operators shift and reset. We consider two different notions of contextual equivalence: one that does not require the presence of a top-level control delimiter when executing tested terms, and another one, fully compatible with the original CPS semantics of shift and reset, that does. For each of them, we develop sound ...

Purpose: The aim of this study was to compare the effectiveness of Fernaldchr(chr('39')39chr('39'))s multisensory training and computer game training on dyslexia in primary school students with learning disabilities in Ahvaz. Methodology: This study was applied in terms of purpose and in an experimental framework (pre-test-post-test design with control group). The statistical population in the...

In the Serial Reaction Time (SRT) task, participants respond to a set of stimuli the order of which is apparently random, but which consists of repeating sub-sequences. Participants can become sensitive to this regularity, as measured by an indirect test of reaction time, but can remain apparently unaware of the sequence, as measured by direct tests of prediction or recognition. Some researcher...

This study compared fear learning acquired through direct experience (Pavlovian conditioning) and fear learning acquired without direct experience via either observation or verbal instruction. We examined whether these three types of learning yielded differential responses to conditioned stimuli (CS+) that were presented unmasked (available to explicit awareness) or masked (not available to exp...

This article focuses on three themes concerning determinism and indeterminism. The first theme is observational equivalence between deterministic and indeterministic models. Here I discuss several results about observational equivalence and present an argument on how to choose between deterministic and indeterministic models involving indirect evidence. The second theme is whether Newtonian phy...
