As discussed above, the non-specific nature of the representation guiding chicks' preferences had already been proven in previous studies, using both schematic stimuli [8] and naturalistic objects [1] (see the Introduction and Table 1).
These tests measure comprehension in relation to both single words and short sentences, and with regard to both naturalistic objects, body parts, and geometric tokens.
Control experiments in two naturalistic tasks (small object sorting and box stacking) were carried out with the same system as was used for the toolmaking experiments.
Finally, it is interesting to note that previous studies have demonstrated that, in chicks, the development of the predisposition to approach naturalistic (hen-like) objects is influenced by prior exposure to certain types of non-specific experience (e.g. motor activity, manual handling, exposure to abstract visual patterns) (e.g. [53]).
But the intuitionists seem to object to naturalistic accounts of moral properties in precisely this way.
Paintings that are no more than prosaic, naturalistic depictions of everyday objects or human activity would thus appear to fall short of genuine art.
Again, the task was somewhat arbitrary and un-naturalistic, and the unexpected object did not directly affect how people performed the primary task.
In particular, in chicks, research using naturalistic stimuli and real objects demonstrated a preference for the configuration of features contained in the head of a hen using, among others, stimuli that were controlled for texture, outline, stimulus complexity, presence of structure, object-like appearance and approximate symmetry (see Table 1).
First, when learning to manipulate grasped objects in more naturalistic settings the arm is not restricted to a horizontal plane and objects are more akin to simple inertial loads.
People can experience inattentional blindness for a potentially dangerous object in a naturalistic real-world context, even when noticing that object would change how they perform their primary task and even when their training focuses on awareness of potential threats.
