Subliminal stimuli can be deeply processed and activate similar brain areas as consciously perceived stimuli. This raises the question which signatures of neural activity critically differentiate conscious from unconscious processing. Transient synchronization of neural activity has been proposed as a neural correlate of conscious perception. Here we test this proposal by comparing the electrophysiological responses related to the processing of visible and invisible words in a delayed matching to sample task. Both perceived and nonperceived words caused a similar increase of local (gamma) oscillations in the EEG, but only perceived words induced a transient long-distance synchronization of gamma oscillations across widely separated regions of the brain. After this transient period of temporal coordination, the electrographic signatures of conscious and unconscious processes continue to diverge. Only words reported as perceived induced (1) enhanced theta oscillations over frontal regions during the maintenance interval, (2) an increase of the P300 component of the eventrelated potential, and (3) an increase in power and phase synchrony of gamma oscillations before the anticipated presentation of the test word. We propose that the critical process mediating the access to conscious perception is the early transient global increase of phase synchrony of oscillatory activity in the gamma frequency range.

This article describes the role of culture and power in building a research-practice partnership (RPP). The original aims that drove the building of the RPP were to generate and use research to inform the programs and services provided by the youthserving organization to Latinx youth and to use the findings to inform research on how to broaden participation in computing. In this article, we describe how the RPP evolved. Data include documentation from meeting notes, e-mails, and observations as well as interviews with practitioners. The results suggest that the research goals and process changed when the partners began to critically analyze and discuss the role of power and culture, and adjustments to the methods and theoretical grounding of the research were made as a result. The lessons learned are summarized in terms of their implications for generating research that has both theoretical and social justice implications.

A simple and quick general test to screen for numerical anomalies is presented. It can be applied, for example, to electoral processes, both electronic and manual. It uses vote counts in officially published voting units, which are typically widely available and institutionally backed. The test examines the frequencies of digits on voting counts and rests on the First (NBL1) and Second Digit Newcomb-Benford Law (NBL2), and in a novel generalization of the law under restrictions of the maximum number of voters per unit (RNBL2). We apply the test to the 2004 USA presidential elections, the Puerto Rico (1996, 2000 and 2004) governor elections, the 2004 Venezuelan presidential recall referendum (RRP) and the previous 2000 Venezuelan Presidential election. The NBL2 is compellingly rejected only in the Venezuelan referendum and only for electronic voting units. Our original suggestion on the RRP (Pericchi and Torres, 2004) was criticized by The Carter Center report (2005). Acknowledging this, Mebane (2006) and The Economist (US) (2007) presented voting models and case studies in favor of NBL2. Further evidence is presented here. Moreover, under the RNBL2, Mebane's voting models are valid under wider conditions. The adequacy of the law is assessed through Bayes Factors (and corrections of p-values) instead of significance testing, since for large sample sizes and fixed α levels the null hypothesis is over rejected. Our tests are extremely simple and can become a standard screening that a fair electoral process should pass.

The present research demonstrates a dissociation between explicit and implicit intergroup evaluation in the reciprocal attitudes between indigenous (Mapuche) and non‐indigenous Chileans. In both social groups, the explicit measures of attitudes towards the respective in‐group and out‐group were compared with the Implicit Association Test scores. The results indicate that the members of the low‐status minority might explicitly express a moderate evaluative preference for their in‐group but might implicitly devalue it. Conversely, the members of the high‐status majority might implicitly devalue their out‐group but might explicitly express no bias. These results are theoretically framed in terms of system justification, conventional stereotypes and motivated correction processes.

The effects of school inclusion programs on male and female nondisabled students' stereotypes and attitudes toward people with Down syndrome were studied. Nondisabled students (11–15 years of age) from schools with and without inclusion programs reported positive and negative attitudes toward people with Down syndrome. As hypothesized, girls and students attending schools with inclusion programs showed more favorable attitudes toward people with Down syndrome than did boys and students attending schools without inclusion programs, respectively. Interaction effects of school system and sex of participant suggest that boys' attitudes, in particular, benefit from inclusive schooling. The study provides evidence for the effectiveness of inclusion programs in ameliorating prejudice and intergroup anxiety; and in promoting positive attitudes, affect, and trust.
