In a virtual community, the behavior of strengthening the emotion of a post title to draw attention of users is not uncommon, which can affect the overall performance of the information environment. This study focuses on exploring the influence of the emotional information of a post title on the users' community perceived value in a virtual community. Based on the cue utilization theory, we propose a framework with several hypotheses. Data are collected using the experimental method from the college student sample in our study, and numerous tests are performed to analyze the data and verify the hypotheses. At the end of the study, it is found that the emotional information of the post title reduces the user community perceived financial value and it improves the user community perceived recreational value. The analysis of the mediating role reveals that emotional involvement facilitates the relationship between emotional information of post titles and user community perceived recreational value. This study adds a new dimension by discussing the user community value perception on post title expression and it reveals the conflict of interest between the manager of the virtual community and the producers of the post. Our findings may also provide guidelines and references for virtual community managers. Specifically, they should view the behavior of making post titles more emotional critically, and choose specific information management strategies based on the different value pursuit of community users.

The neural bases of the so-called Spatial Cueing Effect in a visuo-auditory version of the Central Cue Posneŕs Paradigm (CCPP) are analyzed by means of behavioral patterns (Reaction Times and Errors) and Event-Related Potentials (ERPs), namely the Contingent Negative Variation (CNV), N1, P2a, P2p, P3a, P3b and Negative Slow Wave (NSW). The present version consisted of three types of trial blocks with different validity/invalidity proportions: 50% valid – 50% invalid trials, 68% valid – 32% invalid trials and 86% valid − 14% invalid trials. Thus, ERPs can be analyzed as the proportion of valid trials per block increases. Behavioral (Reaction Times and Incorrect responses) and ERP (lateralized component of CNV, P2a, P3b and NSW) results showed a spatial cueing effect as the proportion of valid trials per block increased. Results suggest a brain activity modulation related to sensory-motor attention and working memory updating, in order to adapt to external unpredictable contingencies. [ABSTRACT FROM AUTHOR]

Comprehension of an illustrated document can involve complex visual scanning in order to locate the relevant information on the screen when this is evoked in spoken explanations. The present study examined the effects of two types of attention-guiding means (color change or step-by-step presentation of diagram elements synchronized with a spoken explanation) on multimedia learning. These attention-guiding means were expected to facilitate selection of the illustrated information that corresponded to the spoken explanations. The results indicated positive, and in some cases additive, effects on a retention task and on the perceived ease of learning but not on a transfer task. These results are discussed in light of models of multimedia learning. [Copyright &y& Elsevier]

Abstract: The present study investigated how anticipation of a target’s appearance affects human attention to gaze cues provided by a schematic face. Subjects in a ‘catch’ group received a high number of ‘catch’ trials, in which no target stimulus appeared. Subjects in the control group did not receive any catch trials. As in previous studies, both groups showed a facilitation effect to the cued location during shorter stimulus onset asynchrony (SOA). In both groups, an analysis of eye movements confirmed that subjects’ eyes remained on the fixation point, ruling out the possibility that the facilitation effect was due to shifting eye movements (saccades) as opposed to a shift in covert attention. But while the control group’s response time (RT) decreased as SOA increased, the catch group’s RT had a U-shaped pattern and the facilitation effect to the cued location was reversed at the longest SOA (1005ms). These results suggest that subjects in the catch group disengaged their attention during long SOAs because they expected the trial to be a catch trial. This disengagement of attention during long SOAs results in a delay before attention could be re-focused to the previous location regardless of the cue validity [“IOR (inhibition of return)”-like-phenomenon]. Unlike the conventional IOR, we suggest that this “IOR”-like phenomenon caused by an unpredictive central gaze cue is likely to be mediated by an endogenous mechanism. [Copyright &y& Elsevier]
