![]() Pac-Man is great, and I occasionally lose twenty minutes or so to it just as a fun, accessible diversion (especially now I can carry it in my pocket). Minor fluctuations in the actions of one of the ghosts (the Clyde effect, if you will) create completely different experiences for the player. Here we can examine not so much the player's behaviour (though how they respond to being hunted is interesting) the ghost behaviour illustrates how behavioural traits in small groups interact and coordinate in achieving shared goals. Orange ghost (Clyde) behaves randomly to introduce a spot of chaos.Pink ghost (Pinky) and Cyan ghost (Inky) will attempt to ambush him by positioning themselves ahead of Pac-Man.Then add to this individual traits and patterns: If you study the game mechanics of the ghosts' behaviour, it falls into three types: The ghosts in Pac-Man often work together to catch Pac-Man, and the player must anticipate and respond to their movements. This can be used to study how people adapt to new situations and learn from experience.įinally, Pac-Man can be used to study social and group dynamics. In Pac-Man, the maze layout and the ghosts' behaviour can change from level to level, requiring players to adjust their strategy to be successful. This can be used to examine how people weigh different options and make choices under time pressure and other constraints.Īnother way to use Pac-Man to model behaviour is to study how people adapt to changing environments. In Pac-Man, the player must constantly decide which direction to move to avoid the ghosts and collect the dots. One way is to use the game to study decision-making and problem-solving. Using a game like Pac-Man, we can model behaviour in several ways. Screenshot of Pac-Man in all its simple gloryĬompared to almost any open-world game in today's market, it is the equivalent of constructing a mnemonic memory circuit using stone knives and bearskins.īut there's something to be said about the simplicity and purity of Pac-Man. Browning says the climate on the continent has made it challenging.So for the kids out there, Pac-Man is a classic video game in which the player controls a character called Pac-Man, who moves around a maze collecting dots while avoiding ghosts. "It tells us that there was integration, but it could have been from more than one archaic population, in theory."Ĭompared with the Neanderthals, where there is abundant DNA fossil evidence, physical samples are much harder to come by in Africa. "Within Africa, we don't know how many archaic groups might have been involved, and the study doesn't tell us that," she says. It's also possible that the ghost DNA found in this study comes from multiple groups, Browning added. ![]() "I think as we get the genome sequences from different parts of the world at different points in time, there is always the possibility that we might discover these as-yet-unidentified ghost populations," Sankararaman says. He says there is likely evidence of other ghost populations in modern humans in other parts of the world. "Those are all questions which would be fantastic to start thinking about." "Are they just randomly floating in our genomes? Do they have any kind of adaptive benefits? Do they have deleterious consequences?" he added. "That tells us that these archaic populations might have had some DNA that did some useful stuff that's proved to be useful to the modern population," she says.īut at the moment, Sankararaman says, it's not possible to know what, if any, role these genetic materials have for modern humans who carry them. ![]() Shots - Health News Ancient Bone Reveals Surprising Sex Lives Of Neanderthalsīrowning notes that the ghost DNA appears frequently in the genetic material.
