In their paper, Meara and Olmos Alcoy (2010) attempted to find a means of estimating productive second language (L2) vocabulary size based on the premise that many known lexical items simply do not appear in learner-produced texts. To do so, they borrowed an ecological model, in which a capture-recapture formula, the Petersen estimate, is used to…

False memories arising from associatively related lists are a robust phenomenon that resists many efforts to prevent it. However, a few variables have been shown to reduce this form of false memory. Explanations for how the reduction is accomplished have focused on either output monitoring processes or constraints on access, but neither idea alone…

Six lexical decision experiments were conducted to examine the influence of complex structure on the processing speed of English compounds. All experiments revealed that semantically transparent compounds (e.g., "rosebud") were processed more quickly than matched monomorphemic words (e.g., "giraffe"). Opaque compounds (e.g., "hogwash") were also…

Speech sounds can be classified on the basis of their underlying articulators or on the basis of the acoustic characteristics resulting from particular articulatory positions. Research in speech perception suggests that distinctive features are based on both articulatory and acoustic information. In recent years, neuroelectric and neuromagnetic…

This classroom experiment introduces students to the notion of credit risk and expected return, by allowing them to trade on comparable corporate bond issues from two types of markets: investment-grade and high-yield markets. Investment-grade issues have a lower probability of default than high-yield issues and thus provide a lower yield.…

In the present study we analyze how the cognitive system deals on-line with number agreement mismatches and whether this on-line process influences the off-line interpretation of the sentence. In two ERP experiments we monitored the on-line processing consequences of subject-verb agreement mismatches, focusing on the integration of a following…

The behavior of smoke rings, tornados, and quantized vortex rings in superfluid helium has many features in common. These features can be described by the same mathematics we use when introducing Ampere's law in an introductory physics course. We discuss these common features. (Contains 7 figures.)

This paper introduces the notion that fixation and commitment while designing can be measured by studying the protocol of the design session. It is hypothesized that the dynamic entropy of the linkograph of the protocol provides the basis for such a measurement. The hypothesis is empirically tested using a design protocol and the results…

English listeners categorize more of a [k-t] continuum as "t" after [[esh]] than [s] (Mann & Repp, 1981). This bias could be due to compensation for coarticulation (Mann & Repp, 1981) or auditory contrast between the fricatives and the stops (Lotto & Kluender, 1998). In Japanese, surface [[esh]k, [esh]t, sk, st] clusters…

Mitochondria are surrounded by two membranes (outer and inner mitochondrial membrane) that separate two mitochondrial compartments (intermembrane space and matrix). Hundreds of proteins are distributed among these submitochondrial components. A simple biochemical/immunological procedure is described in this test to determine the localization of…

Three experiments examined the role of reference directions in spatial updating. Participants briefly viewed an array of five objects. A non-egocentric reference direction was primed by placing a stick under two objects in the array at the time of learning. After a short interval, participants detected which object had been moved at a novel view…

We examined whether view combination mechanisms shown to underlie object and scene recognition can integrate visual information across views that have little or no three-dimensional information at either the object or scene level. In three experiments, people learned four "views" of a two dimensional visual array derived from a three-dimensional…

Terms to be familiar with before you start to solve the test: ion exchange chromatography, polynucleotides, oligonucleotides, radioactive labeling, template, primer, DNA polymerase, reverse transcriptase, helicase, nucleoside triphosphates, nucleoside diphosphates, nucleoside monophosphates, nucleosides, 5'-end and 3'-end, bacteriophage,…

The main aim of this study is to investigate the biased effects which affect scientific researches; although most of the researchers ignore them, and make criticism of the experimental works in the educational field, based on this viewpoint. For this reason, a quasi-experimental process has been carried out with five different student teachers…

A simple and direct method for measuring the absorption of carbon dioxide by two different substances is described. Lithium hydroxide has been used for decades to remove the gas from enclosed living spaces, such as spacecraft and submarines. The ratio of the mass of carbon dioxide absorbed to the mass of lithium hydroxide used obtained from this…
