Visual resemblance and interaction history jointly constrain pictorial meaning.

ABSTRACT: How do drawings-ranging from detailed illustrations to schematic diagrams-reliably convey meaning? Do viewers understand drawings based on how strongly they resemble an entity (i.e., as images) or based on socially mediated conventions (i.e., as symbols)? Here we evaluate a cognitive account of pictorial meaning in which visual and social information jointly support visual communication. Pairs of participants used drawings to repeatedly communicate the identity of a target object among multiple distractor objects. We manipulated social cues across three experiments and a full replication, finding that participants developed object-specific and interaction-specific strategies for communicating more efficiently over time, beyond what task practice or a resemblance-based account alone could explain. Leveraging model-based image analyses and crowdsourced annotations, we further determined that drawings did not drift toward "arbitrariness," as predicted by a pure convention-based account, but preserved visually diagnostic features. Taken together, these findings advance psychological theories of how successful graphical conventions emerge.

Project description:OBJECTIVE Minimal aortic injuries (MAIs) are being recognized more frequently due to the increasing use of high-resolution diagnostic techniques. The objective of this case series review was to report the clinical and radiological characteristics and outcomes of a series of patients with MAI. METHODS From January 2000 to December 2011, 54 major blunt trauma patients were admitted to our institution with traumatic aortic injuries. Nine of them presented with MAI, whereas the remaining 45 patients suffered a significant aortic injury (SAI). RESULTS MAIs accounted for 17% of the overall traumatic aortic injuries in our series. Major trauma patients with MAI and SAI were similar regarding the presence of severe associated non-aortic injuries and the expected mortality calculated by injury severity score, revised trauma score and trauma injury severity score. There were no statistically significant differences in in-hospital mortality between MAI (22.2%) and SAI (30.2%). No death in the MAI group was aortic related, whereas five deaths in the SAI group were caused by an aortic complication. The survival of MAI patients was 77.8% at 1 and 5 years. There was no late mortality among MAI patients. The survival of SAI patients was 69.7% at 1 year and 63.6% at 5 and 10 years. None of the seven surviving patients with MAI presented a progression of the aortic injury. In six patients, the intimal tear completely healed in imaging controls, whereas one patient developed a small saccular pseudoaneurysm. CONCLUSIONS Blunt traumas presenting MAI are as severe as traumas that associate SAI and present similar in-hospital mortality. In contrast to SAI traumas, in-hospital mortality due to MAI is not usually related to the aortic injury, so these injuries are more amenable to a conservative management. It is mandatory to perform a close imaging surveillance to detect early any potential adverse evolution of an MAI. Nevertheless, a balance must be struck between a close serial imaging surveillance and the potentially detrimental effects of obtaining high-resolution additional images.

Project description:Long-term biodiversity experiments have shown increasing strengths of biodiversity effects on plant productivity over time. However, little is known about rapid evolutionary processes in response to plant community diversity, which could contribute to explaining the strengthening positive relationship. To address this issue, we performed a transplant experiment with offspring of seeds collected from four grass species in a 14-year-old biodiversity experiment (Jena Experiment). We used two- and six-species communities and removed the vegetation of the study plots to exclude plant-plant interactions. In a reciprocal design, we transplanted five "home" phytometers (same origin and actual environment), five "away-same" phytometers (same species richness of origin and actual environment, but different plant composition), and five "away-different" phytometers (different species richness of origin and actual environment) of the same species in the study plots. In the establishment year, plants transplanted in home soil produced more shoots than plants in away soil indicating that plant populations at low and high diversity developed differently over time depending on their associated soil community and/or conditions. In the second year, offspring of individuals selected at high diversity generally had a higher performance (biomass production and fitness) than offspring of individuals selected at low diversity, regardless of the transplant environment. This suggests that plants at low and high diversity showed rapid evolutionary responses measurable in their phenotype. Our findings provide first empirical evidence that loss of productivity at low diversity is not only caused by changes in abiotic and biotic conditions but also that plants respond to this by a change in their micro-evolution. Thus, we conclude that eco-evolutionary feedbacks of plants at low and high diversity are critical to fully understand why the positive influence of diversity on plant productivity is strengthening through time.
