The Posner cueing paradigm is one of the most widely used paradigms in attention research. Importantly, when employing it, it is critical to understand which type of orienting a cue triggers. It has been suggested that large effects elicited by predictive arrow cues reflect an interaction of involuntary and voluntary orienting. This conclusion is based on… (More)
The goal of the present research was to study the relative role of facial and acoustic cues in the formation of trustworthiness impressions. Furthermore, we investigated the relationship between perceived trustworthiness and perceivers confidence in their judgments. 25 young adults watched a number of short clips in which the video and audio channel were… (More)
Seven xanthanolides were identified in the extract of X. italicum leaves. Antibacterial and cytotoxic activities were found for the total extract and its major constituents xanthinin and xanthatin.
The aerial parts of Achillea setacea afforded, in addition of a rare monoterpene triol and 12 known sesquiterpene lactones, a new guaianolide containing an endoperoxide ring. Its structure was elucidated by spectral methods.
The aerial parts of A. chrysocoma and A. coarctata afforded 22 and 9 sesquiterpene lactones, respectively. All the compounds described are new for the studied species. The lactones 5, 6 and 12 are new for the genus Achillea.
Most past work on trustworthiness perception has focused on the structural features of the human face. The present study investigates the interplay of dynamic information from two channels – the face and the voice. By systematically varying the level of trustworthiness in each channel, 49 participants were presented with either facial or vocal information,… (More)
A new bis-norsesquiterpene lactone, spirodepressolide (1), has been isolated from the aerial parts of Achillea depressa Janka and its structure determined by spectroscopic methods to have a new 4-methyl-7-methylethyl-spirobicyclo[4,4]nonane skeleton.
