Individual factors like gender and familiarity can affect the kind of environmental representation that a person acquires during spatial navigation. Men seem to prefer relying on map-like survey representations, while women prefer using sequential route representations. Moreover, a good familiarity with the environment allows more complete environmental representations. This study was aimed at investigating gender differences in two different object-position learning tasks (i.e., Almeria Boxes Tasks) assuming a route or a survey perspective also considering the role of environmental familiarity. Two groups of participants had to learn the position of boxes placed in a virtual room. Participants had several trials, so that familiarity with the environment could increase. In both tasks, the effects of gender and familiarity were found, and only in the route perspective did an interaction effect emerge. This suggests that gender differences can be found regardless of the perspective taken, with men outperforming women in navigational tasks. However, in the route task, gender differences appeared only at the initial phase of learning, when the environment was unexplored, and disappeared when familiarity with the environment increased. This is consistent with studies showing that familiarity can mitigate gender differences in spatial tasks, especially in more complex ones.

Objective: This research examined whether negative and positive arousal emotions modify the relationship between experience level and cue utilization among anesthetists. Background: The capacity of a practitioner to form precise associations between clusters of features (e.g., symptoms) and events (e.g., diagnosis) and then act on them is known as cue utilization. A common assumption is that practice experience allows opportunities for cue acquisition and cue utilization. However, this relationship is often not borne out in research findings. This study investigates the role of emotional state in this relationship. Method: An online tool (EXPERTise 2.0) was used to assess practitioner cue utilization for tasks relevant to anesthesia. The experience of positive and negative arousal emotions in the previous three days was measured, and emotion clusters were generated. Experience was measured as the composite of practice years and hours of practice experience. The moderating role of emotion on the relationship between experience and cue utilization was examined. Results: Data on 125 anesthetists (36% female) were included in the analysis. The predicted interaction between arousal emotions and the experience level emerged. In particular, post hoc analyses revealed that anxiety-related emotions facilitated the likelihood of high cue utilization in less experienced practitioners. Conclusion: The findings suggest a role for emotions in cue use and suggest a functional role for normal range anxiety emotions in a simulated work-relevant task. Application: This research illustrates the importance of understanding the potentially functional effects common negative arousal emotions may have on clinical performance, particularly for those with less experience.

AbstractIncreasing surgical refinement of procedures to meet both biologic and esthetic demands of patients is seen in today's periodontal practice. For these new technologies, instruments, and surgical techniques are necessary. Technical skills of the clinician are challenged by the limit of range of visual acuity. Periodontal microsurgery improves the outcome of basic periodontal surgical procedures by enhancing normal vision through magnification along with favorable lighting system. It gives enhanced outcomes not possible with traditional macrosurgery in terms of passive wound closure and reduced tissue trauma. The purpose of this review is to provide brief knowledge of periodontal microsurgery: the role of magnification, microsurgical instrumentation and applications of microsurgery.

Goal-directed navigation is a crucial behavior for the survival of animals, especially for the birds having extraordinary spatial navigation ability. In the studies of the neural mechanism of the goal-directed behavior, especially involving the information encoding mechanism of the route, the hippocampus (Hp) and nidopallium caudalle (NCL) of the avian brain are the famous regions that play important roles. Therefore, they have been widely concerned and a series of studies surrounding them have increased our understandings of the navigation mechanism of birds in recent years. In this paper, we focus on the studies of the information encoding mechanism of the route in the avian goal-directed behavior. We first summarize and introduce the related studies on the role of the Hp and NCL for goal-directed behavior comprehensively. Furthermore, we review the related cooperative interaction studies about the Hp-NCL local network and other relevant brain regions supporting the goal-directed routing information encoding. Finally, we summarize the current situation and prospect the existing important questions in this field. We hope this paper can spark fresh thinking for the following research on routing information encoding mechanism of birds.

The flashed face distortion effect is a phenomenon whereby images of faces, presented at 4–5 Hz in the visual periphery, appear distorted. It has been hypothesized that the effect is driven by cortical, rather than retinal, components. Here, we investigated the role of peripheral viewing on the effect. Normally sighted participants viewed the stimulus peripherally, centrally, and centrally with a blurring lens (to match visual acuity in the peripheral location). Participants rated the level of distortion using a Visual Analogue Scale. Although optical defocus did have a significant effect on distortion ratings, peripheral viewing had a much greater effect, despite matched visual acuity. We suggest three potential mechanisms for this finding: increased positional uncertainty in the periphery, reduced deployment of attention to the visual periphery, or the visual crowding effect.
