![]() ![]() Moreover, there is an ongoing debate among scientists about the merits or harm of anthropomorphism in the scientific study of animal behavior and in scientific discourse.ĭespite the interest and the specificity of the topic most of the relevant studies are scattered across disciplines and have not built a systematic research framework. Psychologists have set out to understand which aspects of human mind are involved in this behavior, its motivations and the circumstances favoring its enactment. The pervasiveness of this phenomenon makes it a particularly interesting object of psychological enquiry. Furthermore, a systematized form of anthropomorphism underlies most religions. In everyday life humans speak of events such as fires as if they possessed some form of intentionality, a behavior sometimes shared also by scientists. Adults often attribute mental states and emotions to animals. It is frequent to see children addressing dolls and figures as if they were alive. SEYMOUR.The attribution of human traits to non-humans - animals, artifacts or even natural events - is an attitude, deeply grounded in human mind. The screw acts as a motor and brake, and the fans will not only be moved to position but securely held in the position selected. ![]() overcome the resistance of the air to change the position of the fans. The use of a device having a free endwise movement would, however, require a friction or other device to. Said screw may be allowed an endwise movement, and then by pushing or pulling it will act as a rack to cause the rapid movement required or a rack might be substituted for the screw without changing the principle of operation. As the head D and fans are continually revolving with the shaft G, it is only necessary to seize and hold fast the hand-hold i, and thus arrest the revolution of the screw H, to change as desired the adjustment more rapidly than by the action of the screw H. The stem h of the screw H projects to a point within convenient reach of the operators hand and is provided with a handhold, 2.
