The purpose of this study was to investigate the cue congruency effect of auditory stimuli during visual search in dynamic environments. Twenty-eight participants were recruited to conduct a visual search experiment. The experiment applied auditory stimuli to understand whether they could facilitate visual search in different types of background. Additionally, target location and target orientation were manipulated to clarify their influences on visual search. Target location was related to horizontal visual search and target orientation was associated with visual search for an inverted target. The results regarding dynamic backgrounds reported that target-congruent auditory stimuli could speed up the visual search time. In addition, the cue congruency effect of auditory stimuli was critical for the center of the visual display but declined for the edge, indicating the inhibition of horizontal visual search behavior. Moreover, few improvements accompanying auditory stimuli were provided for the visual detection of non-inverted and inverted targets. The findings of this study suggested developing multisensory interaction with head-mounted displays, such as augmented reality glasses, in real life.

For the purpose of studying the epigenetic characteristics of the mitochondrial genome of the ridgetail white prawn, Exopalaemon carinicauda (Holthuis, 1950) under Cd2+ and Cr6+ heavy metal stress, the mitochondrial DNA methylation of E. carinicauda was analysed by bisulfite sequencing PCR (BSP). Many methylation sites were found at the 3′ end sequence of COX3 and at the starting region sequence of ND3, while only a few methylation sites were found at the 3′ end sequence of ND5. The mitochondrial genome was inferred to regulate the energy metabolism through the methylation process. In addition, under Cd2+ stress, mitochondrial DNA methylation was more common, and found during all stress periods (3, 6, 12, 24, 48, 72 and 96 h), while under Cr6+ stress, mitochondrial DNA methylation was less common, mainly occurring after 48 hours of stress. The sensitivity of the mitochondrial genome response to Cd2+ stress was inferred to be greater than that to Cr6+. This study revealed for the first time that methylation occurs in the mitochondrial genome of E. carinicauda in response to heavy metal stress.
