Moreover, it is only a weak cue to scene change – only 40% as potent as color change and only 4% as potent as time or location changes taken together (Cutting et al., 2012).
Error-correction theories of learning would then predict that the overshadowing of the weak cue on the strong cue will be negligible (e.g., Mackintosh, 1976).
Although colour is a rather weak cue, in combination with the interest point proximity it helps to avoid a hard threshold.
Probes in the non-matching condition (50% of total trials) were either the product of the cue numbers (strong cue-probe association), the multiple of either cue numbers (weak cue-probe association), or an arithmetically neutral number with respect to the cue numbers (no cue-probe association).
Galfano, Penolazzi, Vervaeck, Angrilli, and Umiltà (2009) used a paradigm in which non-matching probes could either be the product of both cue numbers (strong cue-probe association), the multiple of one of the cue numbers (weak cue-probe association), or an arithmetically neutral number with respect to the cue numbers (no cue-probe association).
However, the current experiment does not address this feature-selective guidance and it would require further experiments to verify why orientation is a weaker cue for top-down attention in the presence of other features.
Thus, under normal conditions, these weaker cues would be superseded by stronger influences of retinal origin, leading to a nonsymmetric, retinotopically matched callosal map.
The present results suggest that there may be a long-lived dysfunction present, which the majority of the time manifests as poor sleep quality and at specific times of the year perhaps when entrainment by natural light cues is weaker, results in periodic disinhibition of the trigeminal autonomic reflex.
However, a finding that nectar-feeding bats would fail to form associations between scents and food rewards might result from our having used very salient shape cues and relatively weak scent cues.
To test this hypothesis that meal time would be a weak entraining cue for the pituitary circadian oscillators, we submitted mice to temporal feeding restriction under a 12L:12D cycle.
This weak positional cue in a shallow gradient may induce a bias of pseudopod relatively easy in the activating environment of the splitting pseudopod, but more difficult in the cell body.
