ObjectiveThe objective of this study was to validate the computerized Symbol Digit Modalities Test in a Swiss pediatric cohort, in comparing the Swiss sample to the Canadian norms. Secondly, we evaluated sex effects, age-effects, and test–retest reliability of the c-SDMT in comparison to values obtained for the paper and pencil version of the Symbol Digit Modalities Test.MethodsThis longitudinal observational study was conducted in a single-center setting at the University Children’s Hospital of Bern. Our cohort consisted of 86 children aged from (...) 8 to 16 years. The cohort included both healthy participants and patients hospitalized for a non-neurological disease. Forty eight participants were assessed during two testing sessions with the SDMT and the c-SDMT.ResultsTest–retest reliability was high in both tests. A reliable change index was calculated for the SDMT and the c-SDMT corrected for practice effects. While a significant age effect on information processing speed was observed, no such effect was found for sex. When data on the c-SDMT performance of the Swiss cohort was compared with that from a Canadian cohort, no significant difference was found for the mean time per trial in any age group. Norm values for age groups between 8 and 16 years in the Swiss cohort were established.ConclusionNorms for the c-SDMT between the Swiss and the Canadian cohort were comparable. The c-SDMT is a valid alternative to the SDMT. It is a feasible and easy to administer bedside tool due to high reliability and the lack of motor demands. (shrink)

BackgroundInformation processing speed is a marker for cognitive function. It is associated with neural maturation and increases during development. Traditionally, IPS is measured using paper and pencil tasks requiring fine motor skills. Such skills are often impaired in patients with neurological conditions. Therefore, an alternative that does not need motor dexterity is desirable. One option is the computerized symbol digit modalities test, which requires the patient to verbally associate numbers with symbols.MethodsEighty-six participants were examined, 38 healthy and 48 hospitalized for (...) a non-neurological disease. All participants performed the written SDMT, c-SDMT, and the Test of Non-verbal Intelligence Fourth Edition. Statistical analyses included a multivariate analysis of covariance for the effects of intelligence and hospitalization on the performance of the SDMT and c-SDMT. A repeated measures analysis of variance was used to compare performance across c-SDMT trials between inpatients and outpatients.ResultsThe MANCOVA showed that hospitalization had a significant effect on IPS when measured with the SDMT but not with the c-SDMT, while IQ had no effect on IPS. Age was the best predictor of performance of both tests. The repeated measures ANOVA revealed no significant difference in within-test performance between outpatient and inpatient participants in the c-SDMT.ConclusionPerformance of the c-SDMT is not confounded by hospitalization and gives within-test information. As a valid and reliable measure of IPS for children and adolescents, it is suitable for use in both inpatient and outpatient populations. (shrink)

Two experiments investigated whether motion metaphors for time affected the perception of spatial motion. Participants read sentences either about literal motion through space or metaphorical motion through time written from either the ego‐moving or object‐moving perspective. Each sentence was followed by a cartoon clip. Smiley‐moving clips showed an iconic happy face moving toward a polygon, and shape‐moving clips showed a polygon moving toward a happy face. In Experiment 1, using an explicit judgment task, participants judged smiley‐moving cartoons as related to (...) ego‐moving sentences about space and about time, and shape‐moving cartoons as related to object‐moving sentences. In Experiment 2, participants viewed the same stimuli, but the cartoons were task‐irrelevant. Event‐related brain potentials revealed an early attentional effect of congruity on cartoons following sentences about space, and a later semantic effect on cartoons following sentences about time. Results are most consistent with accounts that posit differences in the processing of novel and conventional metaphors. (shrink)

Agriculture occupies 38% of the planet’s terrestrial surface, using 70% of freshwater resources. Its modern practice is dominated by an industrial–productivist discourse, which has contributed to the simplification and degradation of human and ecological systems. As such, agricultural transformation is essential for creating more sustainable food systems. This paper focuses on discursive change. A prominent discursive alternative to industrial–productivist agriculture is regenerative agriculture. Regenerative discourses are emergent, radically evolving and diverse. It is unclear whether they have the potential to generate (...) the changes required to shift industrial–productivist agriculture. This paper presents a literature-based discourse analysis to illustrate key thematic characteristics of regenerative agricultural discourses. The analysis finds that such discourses: situate agricultural work within nested, complex living systems; position farms as relational, characterised by co-evolution between humans and other landscape biota; perceive the innate potential of living systems as place-sourced; maintain a transformative openness to alternative thinking and practice; believe that multiple regenerative cultures are necessary for deeply regenerative agriculture; and depart from industrialism to varying degrees. The paper concludes by reviewing three transformative opportunities for regenerative discourses—discourse coalitions, translocal organising and collective learning. (shrink)

Time–space synesthetes report that they experience the months of the year as having a spatial layout. In Study 1, we characterize the phenomenology of calendar sequences produced by synesthetes and non-synesthetes, and show a conservative estimate of time–space synesthesia at 2.2% of the population. We demonstrate that synesthetes most commonly experience the months in a circular path, while non-synesthetes default to linear rows or rectangles. Study 2 compared synesthetes’ and non-synesthetes’ ability to memorize a novel spatial calendar, and revealed better (...) performance in synesthetes. The capacity to learn mappings between arbitrary spatial forms and temporal sequences is present in all individuals, and time–space synesthetes’ enhanced visuo-spatial memory abilities may underlie their creation of idiosyncratic spatial calendar forms.

We analyze conceptual patterns shared by Michael Ende’s novel about time, Momo, and examples of time conceptualization from psychology, sociology, economics, conventional language, and real social practices. We study three major mappings in the materialization of time: time as money in relation with time banking, time units as objects produced by an internal clock, and time as a substance that flows. We show that binary projections between experiential domains are not enough to model the complexity of meaning construction in these (...) widely successful examples. To account for the intricacies of time materialization in context, we use generic integration templates, models for conceptual templates based on Fauconnier and Turner’s Blending Theory. The interplay of such detailed patterns with pragmatic and cultural factors, including diachronic aspects, is crucial to identify the cognitive models at work, and the factors that guide their instantiations as a variety of surface products. The blending model for the spatialized time can be refined and extended to the materialization of time. (shrink)

Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned future systems will need (...) to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent. (shrink)

Current research on choice overload has been mainly conducted with choice options not associated with specific brands. This study investigates whether the presence of brand names in the choice set affects the occurrence of choice overload. Across four studies, we find that when choosing among an overabundance of alternatives, participants express more positive feelings (i.e., higher satisfaction/confidence, lower regret and difficulty) when all the options of the choice set are associated with familiar brands, rather than unfamiliar brands or no brand (...) at all. We also find that choice overload only appears in the absence of brand names, but disappears when all options contain brand names—either familiar or unfamiliar. Theoretical and practical implications are discussed. (shrink)
