Subjective organization and the visibility of illusory contours

The effects of the differential organization of a Necker cube on the perceived salience of an embedded illusory triangle were examined. Overall figural salience was greater when the triangle appeared to be localized on the front rather than the back cube face. Illusory contour salience also increased with increasing inducing area contrast and was greater when the figure was oriented on cardinal as compared to oblique coordinates. However, the latter effects were independent of perceived location within the cube. The finding that subjective organizational and structural factors influenced the perceived salience of the illusory figure but did not interact is consistent with van Tuijl and Leeuwenberg's (1982) suggestion that top-down and bottom-up determinants can operate independently in illusory contour perception.     

You can't always get what you want: educational attainment, agency, and choice

Using educational attainment to indicate socioeconomic status, the authors examined models of agency and effects of choice among European American adults of different educational backgrounds in 3 studies. Whereas college-educated (BA) participants and their preferred cultural products (i.e., rock music lyrics) emphasized expressing uniqueness, controlling environments, and influencing others, less educated (HS) participants and their preferred cultural products (i.e., country music lyrics) emphasized maintaining integrity, adjusting selves, and resisting influence. Reflecting these models of agency, HS and BA participants differently responded to choice in dissonance and reactance paradigms: BA participants liked chosen objects more than unchosen objects, but choice did not affect HS participants' preferences. Results suggest that HS and BA models of agency qualitatively differ, despite overlap between HS and BA worlds.     

The relationship between short-term memory and working memory: complex span made simple?

This experiment addresses the question of what makes a working memory measure a good predictor of higher-level abilities. Verbal and visuospatial processing episodes were interleaved with distinct verbal and visuospatial storage episodes to form four complex span tasks. Although these measures were reliable predictors of reading and mathematics ability in children, they were no more predictive of these abilities than corresponding simple span tasks involving storage alone. However, when individual differences in storage ability and processing capacity were controlled for, residual variance in complex span performance was related to academic ability in some cases. These findings indicate that complex span tasks are multiply determined, and that differences in task structure can dramatically influence the relative importance of these multiple constraints and the predictive power of a complex span measure.     

Intimacy, Psyche, and Spirit in the Experience of Chinese and Japanese Calligraphy

In the West, we have adoped the word calligraphy to describe Chinese and Japanese writing out of the recognition that there is an aesthetic component inherent in the written characters. The author shows how Chinese and Japanese calligraphy is much more than writing; it must be approached as one would any piece of art. A brief history of Chinese and Japanese calligraphy is explored, including the elements and methods of brushwork and overall creation of the expressions themselves. The article concludes by looking at how calligraphy is a mode of self-discovery and self-development that opens us to a substantial dialogue between cultures and the paths of inner conversation.

Some men like it black,some women like it pink: consumer implications of differences in male and female website design

• The World Wide Web doubles in size roughly every 2–3 months and dramatic claims are made about the effectiveness of Web‐based commercial efforts. The centrality of non‐price mechanisms of differentiation to the perception, enjoyment and ease of use felt using websites is acknowledged but the only statistically rigorous studies of factors such as form and content have been conducted within a universalist paradigm of aesthetics. This paper reports on an interactionist approach to web aesthetics involving an analysis of 60 male‐ and female‐produced websites. The analysis reveals statistically significant differences between the male‐ and female‐produced websites on 13 out of the 23 factors analysed. These differences span issues of navigation as well as linguistic and visual content. The paper argues that the appeal of websites can be maximised if they mirror the needs and interests of their target populations and that websites targeted at male or female dominated markets need to reflect the aesthetic diversity found in the male‐ and female‐produced websites analysed here. It also presents information on the demographics of the IT profession, showing that there is a potential imbalance between the percentage of women involved online and those involved in the IT profession. This suggests that the male domination of the IT profession could be a barrier to the effective mirroring of female Website preferences.

Nanoscale inclusions in the phonon glass thermoelectric material Zn4Sb3

We have investigated the thermoelectric material Zn₄Sb₃ using transmission electron microscopy (TEM). Nanoscale inclusions with a diameter of about 10 nm were observed, constituting on the order of 1% by volume of the material. Studies using energy filtered imaging, electron diffraction, and high-angle annular dark-field STEM indicate that the inclusions consist of Zn. These inclusions are expected to scatter the medium and long-wavelength phonons effectively, thus contributing to phonon glass behavior which results in the exceptionally low thermal conductivity for this thermoelectric material.
