Summary of "Distances on hills look farther than distances on flat ground: Evidence from converging measures."

Distances on hills are judged as farther than when the same distance is presented on the flat ground. The hypothesized reason for this difference is because perception is influenced by the increased effort required to walk up a hill than to walk the same distance on flat ground. Alternatively, distances presented up a hill might be judged as farther for other, nonperceptual reasons such as bias from demand characteristics. To test whether distances on hills are perceived as farther or are merely judged as farther, we used a variety of measures, including visual matching and blindwalking tasks, and found similar effects across all measures. This convergence is consistent with a perceptual explanation. Second, we mined our data with the goal of making recommendations for future research on this paradigm. Although all of the perceptual measures used showed similar effects, visual matching was the only measure that had good intrasubject reliability. We recommend that future research on this action-specific effect could use any measure unless the research is geared towards individual differences, in which case, only the visual matching measure of perceived distance should be used.

DNA word analysis based on the distribution of the distances between symmetric words.

We address the problem of discovering pairs of symmetric genomic words (i.e., words and the corresponding reversed complements) occurring at distances that are overrepresented. For this purpose, we de...

Probabilistic Distances Between Trees.

Most existing measures of distance between phylogenetic trees are based on the geometry or topology of the trees. Instead, we consider distance measures which are based on the underlying probability d...

Vowels in infant-directed speech: More breathy and more variable, but not clearer.

Infant-directed speech (IDS) is known to differ from adult-directed speech (ADS) in a number of ways, and it has often been argued that some of these IDS properties facilitate infants' acquisition of ...

Rolling and pitching oscillating foil propulsion in ground effect.

In this paper, we investigate the effect of operating near a solid boundary on the forces produced by harmonically oscillating thrust generating foils. A rolling and pitching foil was towed in a fresh...

Medical and Biotech [MESH] Definitions

Transmission of information over distances via electronic means.

Thin strands of transparent material, usually glass, that are used for transmitting light waves over long distances.
