  Y, ~2 W+ l. I/ y/ C  W4.4 The presence within the group of an individual with superior sensory capabilities (the ability to detect the target at a greater distance) has a beneficial effect on group performance only if the individual is the leader of the group. This is because the leader can literally lead the group to the target. On the other hand, if the individual with superior capabilities is not the leader of the group, the fact that it may discover the target before its companions does not benefit group performance.
4.5 The addition of a communication system allowing an individual that knows the location of the target to communicate this information to other individuals in the group, more or less reverses the results obtained without communication. With communication, large groups without a leader perform better than small groups. This is because the critical factor in groups with communication is the time taken for the first individual to discover the target: this individual will immediately communicate the information to the other individuals in the group. And, as we have already said, in large groups it takes less time for the first individual to discover the target than in small groups.
