“…The use of a platform and precipitous drop enabled the maintenance of the rats viewpoint at a fixed equidistance from both stimuli. Lashley [50] and others [96] have used this assay and different variations on operant discrimination tasks [51, 52] to demonstrate that pigmented rats have pattern vision, and are capable of visual recognition memory. Most importantly they demonstrated a great degree of tolerance to changes in luminance and scale, as well as repetition, occlusion and clutter.…”

Although work in primates on higher-order visual areas has revealed how the individual and concerted activity of neurons correlates with behavioral reports of object recognition, very little is known about the underlying mechanisms for visual recognition memory. Low-level vision, even as early as primary visual cortex (V1) and even in subjects as unsophisticated as rodents, promises to fill this void. Although this latter approach sacrifices interrogation of many of the most astounding features of visual recognition, it does provide experimental constraint, proximity to sensory input, and a wide range of interventional approaches. The tractability of rodent visual cortex promises to reveal the molecular mechanisms and circuits that are essential for a fundamental form of memory.

“…1d was used in the earliest studies examining the relationship between attitudes, attention, and perceptual grouping. Based on his experiments with rats (Krechevski, 1938), Krech viewed perceptual organization as a process that can create a spectrum of outcomes ranging from simpler homogeneous structures (e.g., dots in Fig. 1d grouped into a global homogeneous square pattern without column row differentiation) to more complex differentiated structures (e.g., dots grouped in an array of horizontal lines).…”

Attention modulates spatio-temporal grouping

Dynamic stimuli are ubiquitous in natural viewing conditions implying that grouping operations need to operate, not only in space, but also jointly in space and time. Moreover, in natural viewing, attention plays an important role in controlling how resources are allocated. We investigated how attention interacts with spatiotemporal perceptual grouping by using a bistable stimulus, called the Ternus-Pikler display. Ternus-Pikler displays can give rise to two different motion percepts, called Element Motion (EM) and Group Motion (GM), the former dominating at short Inter-Stimulus Intervals (ISIs) and the latter at long ISIs. Our results indicate that GM grouping requires more attentional resources than EM grouping. Different theoretical accounts of perceptual grouping and attention are discussed and evaluated in the light of the current results.

“…Different transfer test procedures were implicated as being responsible for this failure, and it was suggested that additional exploration of the various transfer test procedures should be pursued before the generality of the anomalous effects could be established. Dodwell (1970) and Dodwell , Litner , & Niemi (1970) recently replicated and extended the "anomalous transfer effect" first reported by Krechevsky (1938). Dodwell (1970) used hooded rats and squirrels and taught these Ss a simultaneous discrimination between the stimuli shown in Fig.…”

Two squirrel monkeys and one infant orangutan were trained on a simultaneous discrimination be tween two stimuli that were identical except for a 90-deg difference in or ientation. Subsequent transfer tests failed to reveal reliably the positive and negative anomalous transfer effects, i.e., preference for a solid-line stimulus over the original positive stimulus in the same orientation and preference for the original negative stimulus over a solid-line stimulus in the same orientation, respectively. Different transfer test procedures were implicated as being responsible for this failure, and it was suggested that additional exploration of the various transfer test procedures should be pursued before the generality of the anomalous effects could be established. Dodwell (1970) and Dodwell , Litner , & Niemi (1970) recently replicated and extended the "anomalous transfer effect" first reported by Krechevsky (1938). Dodwell (1970) used hooded rats and squirrels and taught these Ss a simultaneous discrimination between the stimuli shown in Fig. l A, The training stimuli were four dashed lines in either a horizontal or vertical orientation, which he referred to as " rows" and " columns ," respectively. During subsequent transfer tests , Dodwell ( 1970) and Dodwell et al ( 1970) found a preference for four solid lines in the same orientation as the positive training stimulus over the positive training stimulus itself (see Fig. IB for an example). Further, they found a preference for the original negative training stimulus over four solid lines in the same orientation. These results are referred to as positive and negative anomalous transfer effects, respectively. In addition , when both stimuli were solid lines, Dodwell (1970) found a preference for the stimulus in the same orientation as the original positive training stimulus. Finally, when the original positive stimulus was shown along with a stimulus that had solid lines in the same orientation as the original negative stimulus , the original positive stimulus was preferred (Dodwell , 1970) . These results were taken as additional evidence tha t the anomalous effects are not simply a novelty effect.
