“…The comparison between the first and the last two experiments shows that not all visual discriminations are equally easy to learn for this model species. This appears to be in line with previous studies reporting uneven performances in zebrafish trained to discriminate different shape pairs, and specifically with crosses ([ 47 , 48 ] see the Introduction and see also [ 51 , 62 – 66 ] for evidence in other fish species). One hypothesis thus could be that, also in the task employed here, zebrafish show uneven performance when different shape pairs are used.…”

Visual discrimination and amodal completion in zebrafish

et al. 2022

While zebrafish represent an important model for the study of the visual system, visual perception in this species is still less investigated than in other teleost fish. In this work, we validated for zebrafish two versions of a visual discrimination learning task, which is based on the motivation to reach food and companions. Using this task, we investigated zebrafish ability to discriminate between two different shape pairs (i.e., disk vs. cross and full vs. amputated disk). Once zebrafish were successfully trained to discriminate a full from an amputated disk, we also tested their ability to visually complete partially occluded objects (amodal completion). After training, animals were presented with two amputated disks. In these test stimuli, another shape was either exactly juxtaposed or only placed close to the missing sectors of the disk. Only the former stimulus should elicit amodal completion. In human observers, this stimulus causes the impression that the other shape is occluding the missing sector of the disk, which is thus perceived as a complete, although partially hidden, disk. In line with our predictions, fish reinforced on the full disk chose the stimulus eliciting amodal completion, while fish reinforced on the amputated disk chose the other stimulus. This represents the first demonstration of amodal completion perception in zebrafish. Moreover, our results also indicated that a specific shape pair (disk vs. cross) might be particularly difficult to discriminate for this species, confirming previous reports obtained with different procedures.

“…Likewise, in spontaneous spatial exploration tasks, crosses elicited different responses than other geometric shapes (disks, squares and triangles). In fact, the fish tended to avoid cross stimuli [ 48 ] (see also [ 51 ] for similar evidence in other species).…”

“…In teleosts, extensive visual discrimination studies have been conducted on the goldfish (Carassius auratus) as well as a few other species, demonstrating successful detection and recognition of 2D as well as 3D shapes such as squares, triangles, circles, and rhomboids (Schaller 1926;Herter 1929Herter , 1930Meesters 1940;Sutherland 1964;Wyzisk 2005;Wyzisk and Neumeyer 2007;Siebeck et al 2009). Studies have also shown that fish, like primates and humans, can be deceived by optical illusions (Herter 1930), perceive illusionary contours, for example, Kaniza figures (Wyzisk 2005;Wyzisk and Neumeyer 2007) and recognize partly occluded objects (Sovrano and Bisazza 2008).…”

Visual discrimination and object categorization in the cichlid Pseudotropheus sp.

Object categorization is an important function of the visual system, quickly providing an animal with relevant information about its surrounding and current situation, as for example during predator detection. While the ability to categorize objects has already been observed in several vertebrate and even invertebrate species, no attempt has previously been made to evaluate this function in fish, the most species-rich vertebrate group. This study assessed form discrimination abilities and object categorization skills in the African cichlid Pseudotropheus sp. Fish could discriminate between a variety of two-dimensional geometrical shapes, forms and sizes and learned to distinguish between two categories, "fish" versus "snail". Performance remained undisturbed by extensive modifications to the stimuli, as long as key features were maintained. Results indicate that fish not only memorized the features of the positive stimulus (categorized the positive stimulus), but also categorized the negative stimulus. During transfer trials involving a previously unknown object, fish were able to discriminate between both the negative and the positive stimulus and the unknown stimulus and responded accordingly.

“…Not surprisingly, it has been demonstrated that fish have well developed visual capabilities that match those of other vertebrates (von Frisch, 1914 ; Douglas and Djamgoz, 1990 ; Vallortigara, 2004 ; Brown et al, 2011 ). In the literature we find a number of studies on the perception of shape and color in fish species, showing for example that several Teleost fishes have excellent trichromatic color vision (Beauchamp, 1978 ), as well as the capacity to discriminate two- and three-dimensional shapes (Schaller, 1926 ; Herter, 1929 , 1930 ; Hager, 1938 ; Meesters, 1940 ; Mackintosh and Sutherland, 1963 ; Sutherland, 1964 ; Mark, 1966 ; Wyzisk, 2005 ; Wyzisk and Neumeyer, 2007 ; Siebeck et al, 2009 ; Schluessel et al, 2012 ; Gierszewski et al, 2013 ). Motioperception has also been studied in fish, with a particular attention for model organisms such as zebrafish.…”

Fish are a complex taxonomic group, whose diversity and distance from other vertebrates well suits the comparative investigation of brain and behavior: in fish species we observe substantial differences with respect to the telencephalic organization of other vertebrates and an astonishing variety in the development and complexity of pallial structures. We will concentrate on the contribution of research on fish behavioral biology for the understanding of the evolution of the visual system. We shall review evidence concerning perceptual effects that reflect fundamental principles of the visual system functioning, highlighting the similarities and differences between distant fish groups and with other vertebrates. We will focus on perceptual effects reflecting some of the main tasks that the visual system must attain. In particular, we will deal with subjective contours and optical illusions, invariance effects, second order motion and biological motion and, finally, perceptual binding of object properties in a unified higher level representation.
