Description

Technical Field

[0001] This application relates to the technical field of animal ability detection, and particularly relates to a non-human primate cognitive ability detection device with dual functions. Background Art

[0002] The detection of non-human primate cognitive ability refers to evaluating the cognitive functions of non-human primates (such as monkeys, orangutans, etc.) through experiments. In scientific research, understanding the cognitive abilities, development processes of non-human primates, as well as the similarities and differences with human cognition, can provide important data for research in fields such as cognitive science, psychology, and neuroscience; in animal protection, evaluating the cognitive state of animals in a specific environment can ensure that they receive appropriate care and protection. At the same time, cognitive ability detection can help understand their survival ability and environmental adaptation ability, providing a basis for protection and management measures.

[0003] The experiment of non-human primate hand acquisition of reward items is a way to study the cognitive and motor control abilities of non-human primates; its experimental process usually uses a platform or box with obstacles as the target position, and rewards such as food are set inside the target position to encourage animals to participate in the experiment. The animals need to move their hands around the obstacles to reach the target position.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0054] Please refer to Figure 1 and Figure 2 , a non-human primate cognitive ability detection device with dual functions provided in the embodiments of the present application includes: an experimental table 10, an animal box 20, and a reward box 30.

[0055] The animal box 20 is used for animals to enter; the animals used for experiments here can be, for example, macaques, orangutans, etc. Specifically, an inlet and outlet for animals to enter and exit can be provided at the rear end of the animal box 20, and after the animal enters the animal box 20, the inlet and outlet can be closed so that the animal is temporarily placed in the animal box 20. Among them, the front-rear direction of the animal box 20 can be as Figure 1 shown by the front-rear direction arrow in

[0056] The front end face of the animal box 20 is provided with an opening 21 for the animal's hand to extend out. Specifically, the front end face of the animal box 20 can be in the shape of a railing; the gaps between the railings form the above-mentioned through hole 21, specifically enabling the animal's body not to pass through while only its hand can pass through.

[0057] The front end face of the animal box 20 is provided with a movable baffle 22; the baffle 22 is used to control the opening and closing of the opening 21. As Figure 1 and Figure 2 shown, the baffle 22 can be a transparent or non-transparent structure and can be used for different experiments respectively. The experimental table 10 is arranged at the front end of the animal box 20.

[0058] Please refer to Figure 3 and Figure 4 , a reward product that attracts the animal to pick up is placed inside the reward box 30, for example, it can be food; the reward box 30 is provided with an opening 31 for the animal to reach into its interior; the reward box 30 is movably arranged on the experimental table 10, and the reward box 30 can switch the orientation of the opening 31.

[0059] During the experiment, the opening 31 of the reward box 30 can face forward, backward, left, right, and upward. The length of the experimental table 10 in the left-right direction can be set to be equivalent to the length of the animal box 20 in the left-right direction. When the reward box 30 is placed at different positions and in different orientations on the experimental table 10, it will have different acquisition difficulties for the animals in the animal box 20. Therefore, in this embodiment, in addition to conducting experiments on changing the distance between the reward box 30 and the animal box 20, the experimental difficulty can also be changed by changing the orientation of the opening 31, so that more experimental data can be obtained, which is helpful for the experimenter to analyze the behavior of non-human primates and improve the effectiveness of the experiment.

[0060] The non-human primate cognitive ability detection device with dual functions provided by the above embodiment can be used for obstacle experiments; the experimental process of the obstacle experiment can be: gradually change the distance between the reward box 30 and the central area of the front end face of the animal box 20 from near to far, and keep the orientation of the opening 31 unchanged during the process of changing the distance, and record the acquisition time of the animal each time after the change; then, change the orientation of the opening 31, and once again gradually change the distance between the reward box 30 and the central area of the front end face of the animal box 20 from near to far, and record the acquisition time of the animal each time after the change.

[0061] It should be noted that in the above experiment, the recorded data can include: difficulty coefficient, animal acquisition action, animal's used hand, animal acquisition result, animal acquisition times, animal start time, reward acquisition time, total time, and cognitive level. Among them, the difficulty coefficient can be divided into multiple levels according to the distance of the reward box 30 and the orientation of the opening 31, and different levels have different difficulty coefficients. Among them, the set feeding difficulty and the animal's completion rate are functional indicators for evaluating the prefrontal lobe, and this task can sensitively reflect the executive function of the prefrontal lobe. And this experiment can also be used to determine the dominant hand of the animal and test the finger flexibility of the animal through the feeding difficulty.

[0062] In one embodiment, please refer to Figure 5 , a longitudinal slideway 11 and at least two transverse slideways 12 are provided on the experimental table 10; the two transverse slideways 12 are arranged in parallel at intervals; the longitudinal slideway 11 communicates with the two transverse slideways 12; the length direction of the transverse slideway 12 is perpendicular to the length direction of the longitudinal slideway 11; the length direction of the longitudinal slideway 11 is the front-back direction of the animal box 20.

[0063] In this embodiment, the length direction of the transverse slideway 12 is the left-right direction of the animal box 20; where the left-right direction refers to the direction perpendicular to the front-back direction in the horizontal direction. The two transverse slideways 12 are arranged at intervals in the front-back direction, so that in addition to changing the position of the reward box 30 in the left-right direction, the distance between the reward box 30 and the animal box 20 in the front-back direction can also be changed, improving the variability of the experiment.

[0064] Furthermore, the longitudinal slideway 11 and at least two transverse slideways 12 form an I-shaped structure. The I-shaped structure is a centrosymmetric structure, which is convenient for animals to be experimented at different positions inside the animal box 20; moreover, through the slideway structure of the symmetric structure, it is also possible to experiment whether the acquisition duration and acquisition actions of the animal change when the reward box 30 is located at symmetric left and right positions.

[0065] In one embodiment, the experimental table 10 includes a base 16, a lifting column 13 and a track plate 14; the lifting column 13 is arranged on the base 16; the track plate 14 is arranged on the lifting column 13; the longitudinal slideway 11 and the transverse slideway 12 are arranged on the track plate 14; the lifting column 13 is telescopically arranged. The height of the track plate 14 can be adjusted by the telescopically adjustable lifting column 13.

[0067] The limit pin can be, for example, a screw. The locking holes 15 are located on the sides of the longitudinal slideway 11 and the transverse slideway 12 and can include a plurality of them. The movement of the reward box 30 can be restricted by the limit pins, so that the reward box 30 is fixed on the slideway.

[0068] In one embodiment, the reward box 30 can be a transparent box body, which is convenient for the animals in the experiment to see the rewards.

[0069] In another embodiment, a second reward box 33 is further included; the second reward box 33 is an opaque box body, and a second opening 34 is arranged on the second reward box 33; a lid 32 that can be opened and closed is arranged on the second reward box 33; the lid 32 is used to control the opening and closing of the second opening 34 to change the experimental difficulty.

[0070] The above-mentioned reward box 30 can be used for obstacle experiments; in this embodiment, the second reward box 33 can be used for memory experiments.

[0071] Based on the above embodiment, a movable curtain is arranged at the front end of the baffle 22. The curtain can be used to control whether the animals in the animal box 20 can see the reward box 30, so as to conduct memory experiments.

[0072] The memory experiment may include the following steps: First, set two second reward boxes 33 on the experimental table 10. Then, open the baffle curtain, put a reward in one of the second reward boxes 33, and then close the baffle curtain so that the animal loses sight of the second reward box 33. After a set duration B, open the baffle curtain and observe whether the animal remembers which second reward box 33 the reward is in, and record the duration and the number of errors when the animal obtains the reward. In the experiment, the steps of the above memory experiment can be repeated, and the set duration B of each memory experiment increases sequentially. Among them, the set duration B can be 0. Among them, the way to observe whether the animal remembers can be to see whether the animal will open the cover 32 on the second reward box 33.

[0073] The above memory experiment can be carried out by Figure 5 the detection device shown; different from the reward box 30 being made of a transparent material in the above obstacle experiment, the second reward box 33 used in the memory experiment is made of a non-transparent material, and during the experiment, the second opening 34 of the second reward box 33 can be kept facing upward and is provided with a cover 32. In the memory experiment, the animal can obtain the reward in the second reward box 33 by opening the cover 32.

[0074] Furthermore, it further includes a pull rope 40; the baffle 22 is movably arranged in the vertical direction; a fixed pulley 23 is arranged above the baffle 22 on the animal box 20; a motor is arranged in the animal box 20; one end of the pull rope 40 is connected to the motor, and the other end passes through the fixed pulley 23 and is connected to the baffle 22.
