Description: When objects approach an observer, they can result in either a collision (e.g., a hit) or a non-collision (e.g., a miss). Such objects can also travel on different paths of approach. On a symmetrical path, an object starts in front of the observer but on an asymmetrical path, it starts from either the left or the right. This study examined the eye blink response of 4- to 5-month-old infants' to determine if they perceive collision from non-collision on different paths of approach. The results indicated that objects on a collision path led to more blinking than those on a non-collision path, symmetrical paths produced greater blinking responses than asymmetrical paths, and asymmetrical paths where the object crossed in front of the observer's line of sight produced more blinking than those that did not. These findings suggest that type of contact, and path of approach influence infant's perception of collision.
