This study was conducted to analyze the short-term effects of violent electronic games, played with or without a virtual reality (VR) device, on the instigation of aggressive behavior. Physiological arousal (heart rate (HR)), priming of aggressive thoughts, and state hostility were also measured to test their possible mediation on the relationship between(More)
We propose that we encode and store information as a function of the particular ways we have used similar information in the past. More specifically, we contend that the experience of retrieval can serve as a powerful cue to the most effective ways to encode similar information in comparable future learning episodes. To explore these ideas, we did two(More)
Two experiments were conducted to examine whether children of different ages differ in their ability to reject associative false memories with the Deese-Roediger-McDermott (DRM) paradigm. Two different types of manipulations that are thought to facilitate false memory rejection in adults-slowing the presentation rate and issuing explicit warnings-were(More)
Two experiments attempted to resolve previous contradictory findings concerning developmental trends in false memories within the Deese-Roediger-McDermott (DRM) paradigm by using an improved methodology--constructing age-appropriate associative lists. The research also extended the DRM paradigm to preschoolers. Experiment 1 (N=320) included children in(More)
In this work, we analyze the leishmanicidal effects of epoxy-α-lapachone on Leishmania (Viannia) braziliensis and Leishmania (Leishmania) amazonensis. Promasigotes and amastigotes (inhabiting human macrophages) from both species were assayed to verify the compound's activity over the distinct morphological stages. The incubation with epoxy-α-lapachone led(More)
Several quinonoid and phenazine compounds were synthesized in moderate to high yields and showed activity against H(37)Rv, rifampicin and isoniazid-resistance strains of Mycobacterium tuberculosis. The cytotoxity of the compounds were evaluated against human peripheral blood mononuclear cells (PBMC) and these substances emerge as promising antitubercular(More)
Starting from 2-hydroxy-1,4-naphthoquinone (lawsone), we synthesized eight new 6H-dibenzo[b,h]xanthene derivatives selectively under solvent-free conditions. Spectroscopic investigations confirmed that only the isomer 6H-dibenzo[b,h]xanthene was obtained in all eight cases. Computational studies provide a rationalization for the selective appearance of(More)
The present study analyzed the retrieval dynamics of false recall, using an externalized free-recall task after participants studied Deese/Roediger-McDermott lists with high- and low-identifiable critical words. In Experiment 1, the memory test required participants to write down the words they remembered as having been presented in each list (recall(More)
A series of eighteen quinones and structurally-related oxiranes were synthesized and evaluated for in vitro inhibitory activity against the chloroquine-sensitive 3D7 clone of the human malaria parasite Plasmodium falciparum. 2-amino and 2-allyloxynaphthoquinones exhibited important antiplasmodial activity (median inhibitory concentrations (IC50) < 10 μM).(More)
Twenty-three naphthoimidazoles and six naphthoxazoles were synthesised and evaluated against susceptible and rifampicin- and isoniazid-resistant strains of Mycobacterium tuberculosis. Among all the compounds evaluated, fourteen presented MIC values in the range of 0.78 to 6.25 μg/mL against susceptible and resistant strains of M. tuberculosis. Five(More)
