Эффект ориентации объекта на сенсорных экранах у взрослых и детей
The aim of the study was to compare the performance of adults and children on the object orientation task performed on tablets. In this task, participants decide whether the images of objects on a tablet screen are presented in upright or inverted orientation. Participants respond by tapping the screen with a finger of either hand. The effect of orientation is an acceleration of the motor response in the trials with spatial compatibility of the object’s functional part and the hand used for the response. When presenting the task on a computer monitor, the image perception area and the motor response area are spatially separated. When performing the task on a tablet, they share a common space, which is important for explaining the effect in the embodied cognition account. Initially, we found that in adults who performed the task on the tablet, the object orientation effect was observed only for objects with one functional part (handle). In the case of objects with two functional parts (handle and spout), this effect was found in relation to the other functional part (spout), which defines the spatial directivity of the general form of the object. These results are discussed considering the change of the visual field and its relation to motor actions when performing the task on a tablet. In children, no object orientation effect was found.
