“…Viewing sequence thus matters but most likely matters a good deal less than does 3-D form. This conclusion is in line with previous results suggesting that pure spatial continuity between images is enough to induce the kind of image binding described in temporal association experiments (Perry, Rolls, & Stringer, 2006) and also with the finding that previous experience with specific object rotations is not necessary for robust extrapolation across views (Wang, Obama, Yamashita, Sugihara, & Tanaka, 2005). In general, it may be the case that the sequence of views seen by the observer makes a small enough contribution to the processes governing canonicality, recognition, or generalization across views that removing it from the equation does not cause the visual system to break in a profound way .…”

Objects are best recognized from so-called "canonical" views. The characteristics of canonical views of arbitrary objects have been qualitatively described using a variety of different criteria, but little is known regarding how these views might be acquired during object learning. We address this issue, in part, by examining the role of object motion in the selection of preferred views of novel objects. Specifically, we adopt a modeling approach to investigate whether or not the sequence of views seen during initial exposure to an object contributes to observers' preferences for particular images in the sequence. In two experiments, we exposed observers to short sequences depicting rigidly rotating novel objects and subsequently collected subjective ratings of view canonicality (Experiment 1) and recall rates for individual views (Experiment 2). Given these two operational definitions of view canonicality, we attempted to fit both sets of behavioral data with a computational model incorporating 3-D shape information (object foreshortening), as well as information relevant to the temporal order of views presented during training (the rate of change for object foreshortening). Both sets of ratings were reasonably well predicted using only 3-D shape; the inclusion of terms that capture sequence order improved model performance significantly.

“…The cross-modal nature of the task is crucial. In non-cross-modal tasks, matching can be done at the perceptual level: for example, matching different views of the same face by means of common features perceived through mental rotation (34) or recognizing the different vocalizations of an individual through the presence of unchanged physical features such as formants. On the contrary, in our task, monkeys had to rely on information in memory to match one stimulus, the voice, with the other, the face.…”

Recognition of a particular individual occurs when we reactivate links between current perceptual inputs and the previously formed representation of that person. This recognition can be achieved by identifying, separately or simultaneously, distinct elements such as the face, silhouette, or voice as belonging to one individual. In humans, those different cues are linked into one complex conceptual representation of individual identity. Here we tested whether rhesus macaques (Macaca mulatta) also have a cognitive representation of identity by evaluating whether they exhibit cross-modal individual recognition. Further, we assessed individual recognition of familiar conspecifics and familiar humans. In a free preferential looking time paradigm, we found that, for both species, monkeys spontaneously matched the faces of known individuals to their voices. This finding demonstrates that rhesus macaques possess a cross-modal cognitive representation of individuals that extends from conspecifics to humans, revealing the adaptive potential of identity recognition for individuals of socioecological relevance.cross-species | vocal communication | nonhuman primates | picture recognition I n humans, both faces and voices convey information about identity, providing some of the many cues we use to recognize individuals we know (1). The multifaceted nature of identity code suggests that a complex cognitive representation binds semantic information with information of different sensory modalities. In rhesus monkeys, however, it has typically been assessed only via single-modality information. For instance, rhesus monkeys can discriminate between calls of two conspecifics in a playback experiment using a spontaneous habituation-discrimination paradigm (2). They are also able to discriminate faces of two conspecifics in a match-to-sample task (3) and monkey faces or human faces in visual paired comparison tasks (4-6). These observations demonstrate that monkeys can discriminate idiosyncratic characteristics ("individual A is different from B") for their own or other species. However, they do not provide evidence of individual recognition ("this is individual A, this is B"). In comparison with discrimination, individual recognition requires an additional associative level that allows retrieval of information belonging to a specific individual. In rhesus monkeys, coarse recognition processes such as of their own species, kin, gender, reproductive status, or hierarchy are well documented (2, 7-12). However, these rudimentary recognition abilities fail to account for some sophisticated behaviors that are observed in rhesus macaques' societies. In particular, rhesus macaques live in large groups and maintain elaborate social relations involving, e.g., nonkin alliances during aggressive interactions, fight interference, reciprocal support, friendly grooming, and reconciliation (13-15). Such an organization would benefit well from the finest-grain individual recognition based on a cognitive multimodal representation of identity.Individu...

“…In addition, studies have investigated the tolerance to many other image transformations, such as tolerance for changes in size (Ito et al 1995), illumination (Braje et al 1998), in-plane orientation (Guyonneau et al 2006;Knowlton et al 2009), and orientation in depth (Logothetis et al 1994;Wallis and Bulthoff 2001;Wang et al 2005). In light of behavioral work from Zoccolan and colleagues (Alemi-Neissi et al 2013;Zoccolan et al 2009), we also expect some tolerance to these other transformations somewhere in the rat visual cortex, and on the basis of our present data we hypothesize to find this tolerance to be the strongest in and around area TO.…”

Recent studies have revealed a surprising degree of functional specialization in rodent visual cortex. Anatomically, suggestions have been made about the existence of hierarchical pathways with similarities to the ventral and dorsal pathways in primates. Here we aimed to characterize some important functional properties in part of the supposed "ventral" pathway in rats. We investigated the functional properties along a progression of five visual areas in awake rats, from primary visual cortex (V1) over lateromedial (LM), latero-intermediate (LI), and laterolateral (LL) areas up to the newly found lateral occipito-temporal cortex (TO). Response latency increased Ͼ20 ms from areas V1/LM/LI to areas LL and TO. Orientation and direction selectivity for the used grating patterns increased gradually from V1 to TO. Overall responsiveness and selectivity to shape stimuli decreased from V1 to TO and was increasingly dependent upon shape motion. Neural similarity for shapes could be accounted for by a simple computational model in V1, but not in the other areas. Across areas, we find a gradual change in which stimulus pairs are most discriminable. Finally, tolerance to position changes increased toward TO. These findings provide unique information about possible commonalities and differences between rodents and primates in hierarchical cortical processing.high-level vision; population coding; position tolerance; rodent research; single-unit recordings MONKEYS HAVE BEEN the preferred animal model for vision.
