- Introduction: This article examines the effect of age and gender on somatosensory capacity for children and adolescents, and provides preliminary normative data and reliability for the SenScreen © Kids, a new standardised measure of touch, wrist position sense and haptic object recognition.Method: A cross-sectional study of 88 typically developing children aged 6–15 years (mean 10.3 years; SD 2.6 years) was used to determine the developmental effects of age and gender on somatosensory capacity. Intra-rater reliability was assessed in 22 of the 88 participants at two time points (mean 8.8 years; SD 2.6 years).Results: Statistically significant differences were observed between age groups for tactile discrimination, wrist position sense and haptic object recognition, but not for touch registration for which all except one participant achieved a maximum score. There was no effect of gender. Three of four SenScreen Kids subtests demonstrated good intra-rater agreement between time points.Conclusions: Somatosensory capacity increased with age for typically developing children aged 6–15 years. Three subtests of the SenScreen Kids demonstrated good intra-rater reliability with typically developing children. Further investigation of reliability is required, and all subtests require psychometric testing with clinical populations.

- Aims: Compare haptic exploratory procedures (EPs) and exploratory movements (EMs) of children. This study also tested the interrater reliability of a novel digital recording method.Methods: Participants were 31 children with typical development (TD) (aged 6 years 1 month to 15 years 9 months; 14 male) and 23 children with spastic unilateral cerebral palsy (CP) (aged 6 years to 15 years 5 months; 13 males; right hemiplegia, n = 12).Results: There were no statistically significant differences between groups for expected EP (p =.15), additional EPs (p =.78), or EMs (p =.69) but there was for mean duration of exploration (p <.001) and accuracy (p <.001). This suggests that although children with CP performed similar haptic EPs for each object as children with TD, they took more time and were less accurate in their identification. There was substantial agreement between the two raters' observations of expected EP, κ =.64, p <.0005.Conclusion: Children with CP performed similar haptic EPs as their TD peers. However, despite similarities, the results indicate that for children with CP manual ability was not the primary determinant of accuracy or speed of identification. This study provides evidence for a reliable method of recording haptic EPs.

- •The sensitivity of photosynthetic metabolism to temperature has been identified as a key uncertainty for projecting the magnitude of the terrestrial feedback on future climate change. While temperature responses of photosynthetic capacities have been comparatively well investigated in temperate species, the responses of tropical tree species remain unexplored. •We compared the responses of seedlings of native cold-adapted tropical montane rainforest tree species to exotic warm-adapted plantation species, all growing in an intermediate temperature common garden in Rwanda. Leaf gas exchange responses to CO2 at different temperatures (20 – 40 C) were used to assess the temperature responses of biochemical photosynthetic capacities. •Analyses revealed a lower optimum temperature for photosynthetic electron transport rates than for Rubisco carboxylation rates, along with lower electron transport optima in the native cold-adapted than in the exotic warm-adapted species. The photosynthetic optimum temperatures were generally exceeded by daytime peak leaf temperatures, in particular in the native montane rainforest climax species. •This study thus provides evidence of pronounced negative effects of high temperature in tropical trees and indicates high susceptibility of montane rainforest climax species to future global warming.
