Large-field stimuli were used to investigate the interaction of first- and second-order pathways in transient-stereo processing. Stimuli consisted of sinewave modulations in either the mean luminance (first-order stimulus) or the contrast (second-order stimulus) of a dynamic-random-dot field. The main results of the present study are that: (1) Depth could be extracted with both the first-order ...

Both texture and motion can be strong cues to depth, and estimating slant from texture cues can be considered analogous to calculating slant from motion parallax (Malik and Rosenholtz 1994, report UCB/CSD 93/775, University of California, Berkeley, CA). A series of experiments was conducted to determine the relative weight of texture and motion cues in the perception of planar-surface slant whe...

In stereo capture a stereogram of a crossed illusory figure pulls a texture bounded by the illusory contours to the same depth plane with the illusory figure. We investigated whether three-dimensionally curved and slanted illusory figures could capture a repeating background texture. According to results, stereoscopic capture was perceived when a disparate illusory contour was slanted provided ...

Using dynamic econometric techniques the paper investigates the determinants of private saving in Sri Lanka with a primary focus on the role of financial sector development. Empirical evidence is obtained indicating the existence of the Ricardian equivalence hypothesis, and the significance of credit constraints on private saving. Most significantly, an index of financial sector development var...

Persuasive technologies are growing in popularity and many designers create systems which intentionally change users attitudes or behaviors. This study shows that peoples individual differences in susceptibility to persuasion, as implemented using the six persuasion principles proposed by Cialdini [2], relates to their compliance to a persuasive request which is accompanied by a persuasive cue....

A binocular stimulus that arises when two black frontal plane surfaces located at different depths have a gap between them for one eye but not for the other eye is interesting since the gap is monocular--it has no matching contours in the other eye--and yet binocular processes resolve a depth step effortlessly (Vision Research, 39, 493). In two experiments we investigate the processes and const...

Stereo (front-back) discrimination thresholds were measured in a two-interval forced-choice paradigm for chromatic (red-green) random-dot stereograms that had all detectable longitudinal and transverse aberrations removed by low-pass filtering. The thresholds were measured as a function of the luminance ratio of the red and the green stereo elements. Although individual differences were apparen...

Differential tax analysis is used to show how the optimal mix of inflation tax and direct taxation changes with the relative size of the hidden economy. The larger the relative size of the hidden economy, the smaller the optimal ratio of direct tax to inflation tax. Anecdotal empirical evidence supports this result. JEL Classification: E62, H21, H26, O17.

This paper reports the results of an empirical study which examined the discrimination and identification of prosodic variations by native and non-native speakers of Japanese. The data support the idea that recognizing prosodic cues is easier than associating the correct interpretations with them. This result is in keeping with first language acquisition studies showing that children acquire ac...
