To examine how judgments of learning (JOLs) are made, we used event-related potentials (ERPs) to compare neural correlates of JOLs and successful memory encoding. Participants saw word pairs, and for each made a JOL indicating how confident they were that they would remember the pairing on a later cued recall task. ERPs were recorded while JOLs were made and were separated according to whether ...

We asked if increased awareness of deception enhanced P300-based detection of concealed information with two groups: 1) Control subjects saw a randomized series of either rare probes (subject home towns), frequent irrelevants (other towns), and rare targets, which are irrelevant stimuli but requiring Button 1 responses. Probes and non-target irrelevants required Button 2 responses. Controls wer...

Sometimes people interpret novel noun-noun combinations by transferring a property from one constituent concept of the combination to the other. Two theories make different predictions about these ‘property’ interpretations. Alignment theory predicts that the properties transferred will be alignable differences of the concepts being combined. Constraint theory predicts that the properties trans...

Evidential markers encode the source of a speaker’s knowledge. While some languages express evidentiality by lexical markers (e.g. I saw that it was raining vs. I heard that it was raining), about a quarter of world’s languages grammaticalize evidentiality through specialized markers. For instance, Turkish obligatorily marks all instances of past reference with one of the following two suffixes...

1. The contrast thresholds of a variety of grating patterns have been measured over a wide range of spatial frequencies.2. Contrast thresholds for the detection of gratings whose luminance profiles are sine, square, rectangular or saw-tooth waves can be simply related using Fourier theory.3. Over a wide range of spatial frequencies the contrast threshold of a grating is determined only by the a...

Metasurfaces are a family of novel wavefront-shaping devices with planar profile and subwavelength thickness. Acoustic metasurfaces with ultralow profile yet extraordinary wave manipulating properties would be highly desirable for improving the performance of many acoustic wave-based applications. However, designing acoustic metasurfaces with similar functionality to their electromagnetic count...

This paper deals with the numerical computation of the structural and acoustic response of a building to an incoming wave field generated by high-speed surface railway traffic. The source model consists of a moving vehicle on a longitudinally invariant track, coupled to a layered ground modelled with a boundary element formulation. The receiver model is based on a substructuring formulation and...

The past year was a momentous one for India. The country navigated through the shoals of an unprecedented global financial crisis with only modest negative impact, and successfully continued the world’s largest exercise in democracy. The 15th general election in April-May 2009 saw the venerable Congress Party return to power with a large mandate. On the external front, although ties between Ind...
