This chapter dismantles the common distinction between modernist aestheticism and documentary reference by studying André Gide’s factual writings. In his recollections of his experiences as a juror (Souvenirs de la cour d’assises, 1914) and his reports on court cases in the Nouvelle Revue Française series “Ne jugez pas” (“Judge Not,” 1930), Gide’s ostensibly impersonal organization of testimonial evidence produces a complex polyphonic construction that claims to let documents speak for themselves, while in fact articulating them within a larger discourse. In Voyage au Congo (1927) and Le Retour du Tchad (1928) Gide’s politically engaged writing on French Equatorial Africa enters into dialogue with the largely apolitical documentary film-making practices of his travelling companion Marc Allégret. Commenting on Allégret’s cinematic practices, Gide both reflects on the limitations of documentary and attempts to rival film’s visual capture of living gesture.

Straight Ahead

Perception of visual direction was investigated by requiring subjects repeatedly to adjust a single small light, in an otherwise darkened room, to perceived ‘straight ahead’. This task presumably requires comparing concurrent extra-retinal information (either proprioception or an efference copy) with an internally stored ‘standard’ of comparison. Moment-to-moment precision in that performance is remarkably good, with median threshold (standard deviation) of 47 arc min. Nevertheless, the responses often involved a monotonic shift of direction over a few minutes during a test session in this reduced visual environment. These trends led to final settings that were immediately recognised as grossly erroneous when the room was relit, implying that the presumptive internal standard of comparison, while unstable, can be rapidly updated in a full visual environment. There are clear similarities between this phenomenon and the sudden ‘visual capture’ that occurs in a re-illuminated room, following distortions of visual direction that arose in a similarly reduced setting for subjects whose extraocular muscles were partially paralysed (Matin et al, 1982 Science216 198 – 201). In both cases, the visual stimuli that underlie rapid recalibration are unknown. Among the several possibilities that can be imagined, the strongest candidate hypothesis for this calibration of the straight-ahead direction is that, during fixation in a lit room, one utilises the directional distribution of image motion that arises because of microscale drift of the eye, as it moves toward its equilibrium orientation, much as a moving observer can use optic flow to evaluate ‘heading’ (the dynamic analogue of ‘straight ahead’).

AbstractInformation on alpha (local), beta (between habitats), and gamma (regional) diversity is fundamental to understanding biodiversity as well as the function and stability of community dynamics. The methods like environmental DNA (eDNA) metabarcoding are currently considered useful to investigate biodiversity.We compared the performance of eDNA metabarcoding with visual and capture surveys in estimating alpha/gamma diversity and the variation of the community assemblages of river fish communities, particularly considering community nestedness and turnover.In five rivers across west Japan, with comparing to visual/capture surveys, eDNA metabarcoding detected more species in the study sites, consequently the overall number of species in the region (i.e., gamma diversity) was higher. In particular, the species found by visual/capture surveys were encompassed by those by eDNA metabarcoding.With analyzing the community assemblages between the rivers, we showed the different results between the both methods. While, in the same river, the nestedness and species turnover changing from upstream to downstream did not significantly differ between the both methods. Our results suggest that eDNA metabarcoding may be suitable method, especially for understanding regional community patterns, for fish monitoring in rivers.

Focal Attention

When the visual image of a body part, such as a finger, is doubled by a prism, the ‘felt’ position of that body part is captured by one of its visual images. Moving eye fixation from one to the other visual image is accompanied by a quick shift of the felt position. When focal attention is dissociated from foveation, the former determines visual capture. These new observations underline an active role of focal attention in intersensory integration and sensory—motor coordination of body parts.
