Aquatic species such as bottlenose dolphins can move in 3 dimensions and frequently view objects from different orientations. This study examined their ability to identify 2-D objects visually despite changes in orientation across 2 rotation planes. A dolphin performed a matching-to-sample task in which a sample was presented at a different orientation from its match in a 3-alternative choice array. Samples were presented at 6 aspect angles in the picture plane (0°, ±45°, ±135°, 180°) and 6 aspect angles in the depth plane (0°, -45°, ±90°, +135°, 180°). Alternatives were always presented at 0°. Performance was significantly better than chance for all aspect angles in both rotation plane tests. There was a significant linear decline in accuracy as the sample object was rotated from 0° toward 180° in the picture plane. Performance with familiar objects (M = 97.1%) exceeded performance with novel objects (M = 76.9%). In the depth plane rotation test, there was a significant quadratic trend in accuracy as the sample object was rotated from 0° toward 180°, in which performance was significantly lower at ±90° than at all other orientations. Performance in the picture plane where all object features were available irrespective of orientation was significantly better than performance in the depth plane where the availability of visible features were dependent upon orientation (M = 81.2% vs. M = 63.0%). The dolphin's performance in this study shows evidence of both viewpoint-independent and viewpoint-dependent processes. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

宽吻海豚(Tursiops truncatus)中的视觉感知:成功识别在图片和深度平面中旋转的二维对象。

宽吻海豚等水生生物可以在3维方向上移动,并经常从不同方向观察物体。这项研究检查了它们在2个旋转平面上方向变化的情况下在视觉上识别二维物体的能力。海豚执行了与样品匹配的任务,其中样品以不同于其匹配的方向呈现在3个备选选择数组中。样品在图片平面(0°,±45°,±135°,180°)中以6个纵横比呈现,在深度平面(0°,-45°,±90°,+ 135°, 180°)。替代方案始终以0°呈现。在两个旋转平面测试中,所有纵横比的性能均明显好于机会。当样本对象在图片平面中从0°旋转到180°时,精度存在明显的线性下降。熟悉物体的性能(M = 97.1%)超过了新颖物体的性能(M = 76.9%)。在深度平面旋转测试中,当将样本对象从0°旋转到180°时,精度存在明显的二次趋势,其中±90°的性能明显低于所有其他方向。不论方向如何,所有对象特征均可用的图片平面中的性能明显优于深度平面中的可视性,可视性的可用性取决于方向(M = 81.2%vs. M = 63.0%)。海豚在这项研究中的表现表明了独立于视点和依赖视点的过程的证据。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。在深度平面旋转测试中,当将样本对象从0°旋转到180°时,精度存在明显的二次趋势,其中±90°的性能明显低于所有其他方向。不论方向如何,所有对象特征均可用的图片平面中的性能明显优于深度平面中的可视性,可视性的可用性取决于方向(M = 81.2%vs. M = 63.0%)。海豚在这项研究中的表现表明了独立于视点和依赖视点的过程的证据。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。在深度平面旋转测试中,当将样本对象从0°旋转到180°时,精度存在明显的二次趋势,其中±90°的性能明显低于所有其他方向。不论方向如何,所有对象特征均可用的图片平面中的性能明显优于深度平面中的可视性,可视性的可用性取决于方向(M = 81.2%vs. M = 63.0%)。海豚在这项研究中的表现表明了独立于视点和依赖视点的过程的证据。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。其中在±90°时的性能明显低于所有其他方向。不论方向如何,所有对象特征均可用的图片平面中的性能明显优于深度平面中的可视性,可视性的可用性取决于方向(M = 81.2%vs. M = 63.0%)。海豚在这项研究中的表现表明了独立于视点和依赖视点的过程的证据。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。其中在±90°时的性能明显低于所有其他方向。不论方向如何,所有对象特征均可用的图片平面中的性能明显优于深度平面中的可视性,可视性的可用性取决于方向(M = 81.2%vs. M = 63.0%)。海豚在这项研究中的表现表明了独立于视点和依赖视点的过程的证据。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。在这项研究中的表现表明了独立于观点和依赖观点的过程的证据。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。在这项研究中的表现表明了独立于观点和依赖观点的过程的证据。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。
