Meese's remarks were a response to the state of Texas' execution in September of Charles Rumbaugh Jr., who robbed and killed an Amarillo jeweller in 1975 at the tender age of 17. Rumbaugh's death by lethal injection was the first execution since 1964 of someone sentenced as a minor. Last month, Rumbaugh was succeeded by South Carolina's Terry Roach, who was convicted--also at the age of 17--for criminal sexual assault and two counts of murder. Thirty-one other death-row convicts await capital punishment for crimes committed before the age of legal maturity. Sixteen...
...dropping them on hard surfaces, flying low when their target is small. At the Yerkes Regional Primate Research Center in Atlanta, chimpanzees have been conditioned to communicate through symbols and are able to distinguish between signs that mean food and those that refer to nonedible items. Says Duane Rumbaugh: "Apes have the capacity to use symbols that represent things not present in time and space-the essence of semantics, in human parlance." The chimps also have demonstrated self-awareness. One, while watching itself on a television monitor, directed a flashlight beam into its mouth, apparently curious about what its throat...
...University of California at Santa Barbara, using plastic symbols of different shapes and colors to represent words, taught his prize pupil, Sarah, some 130 words and reported that she had also mastered some phrases. At the Yerkes Regional Primate Research Center in Atlanta, the husband-wife team of Duane Rumbaugh of Georgia State University and Susan Savage-Rumbaugh, employing a language of their own invention, called Yerkish (its symbols are projected onto a screen when an ape presses the appropriately marked key on a console), even got two chimpanzees to communicate with each other in this artificial "tongue...
...researchers are taking a long, hard look at their own work. Premack, now at the University of Pennsylvania, thinks that Terrace's tactic of trying to treat Nim like a human baby was "silly and ill-advised," but he agrees that animals are incapable of spontaneous conversation. The Rumbaughs maintain that their more recent experiments preclude the possibility of trainers giving cues, consciously or sub consciously, to the subjects, but they have their own reservations about the linguistic ability of apes. Acknowledges Duane Rumbaugh: "There is no solid evidence to date that would indicate that...
