This work examines how tactile cues, encoded with azimuth and distance information, compare with visual and speech cues on performance and mental workload in a target detection task. Two experiments are reported using a simulated environment in which targets were presented at varying azimuth and distance locations. In the first experiment, participants engaged targets both while stationary and while in motion using tactile, visual, or speech cues.

- The study analyzed photosynthetic traits of both fast- and slow-growing half-sib families of loblolly and slash pine in northern Florida, focusing on light-saturated net photosynthesis (Amax) and leaf area distribution across different foliage ages.
- In both pine species, Amax was notably higher in newly formed foliage compared to older foliage, and when measured by leaf area, slash pine outperformed loblolly pine, although there was no significant difference when measured by mass.
- Fast-growing families had greater overall leaf area and whole-tree Amax compared to slow-growing families, and a strong correlation was found between tree growth and whole-tree Amax, primarily linked to tree leaf area.
