Description

Technical Field

[0001] The present invention relates to the technical field of biological vision cognitive science, and particularly relates to a training device for avian vision binary classification tasks. Background Art

[0002] Currently, the training of common avian vision binary classification tasks mostly uses a double-arm Y-shaped maze. As shown in Figure 1 and Figure 2 , it includes a training box 1. The cavity of the training box has a waiting area A and an observation area B. It also includes a left arm 2 and a right arm 3 connected to the training box. The left arm has a left channel communicating with the cavity of the training box, and the right arm has a right channel communicating with the cavity of the training box. The intersection area of the left and right channels forms a selection area C. The left and right arms and the training box are arranged in a "Y" shape.

[0003] At the end of the left channel (the end far from the training box), a first image stimulus presentation device 4, that is, a display screen, is provided. At the end of the right channel (the end far from the training box), a second image stimulus presentation device 5 is provided for the bird to make a choice after observation. In order to enable the bird to actively cooperate with the training, a reward and punishment device needs to be added to complete the induction of the bird. When the bird makes a correct choice, corresponding food rewards are given. When the bird makes a wrong choice or does not cooperate with the training, punishment is given, such as high-frequency sounds. A first reward food box 8 is provided at the end of the left channel, a second reward food box 9 is provided at the end of the right channel, and a third reward food box 10 for inducing the bird to return is provided in the waiting area in the cavity of the training box. Electric control gates 6 are also provided in the observation area and the selection area. When the bird observes in the observation area for a period of time, the electric control gate is controlled to open, and the bird enters the selection area to start making a choice. Infrared detectors are provided in the training box and each side channel to judge the position of the bird, and monitors 7 are also provided in each channel.

[0004] The above training device has the following problems: First, the structure is complex and the production is troublesome; Second, the bird needs to walk from the waiting area to the end of the inner channel of one side arm to obtain food, and an unconditional food reward (the third reward food box) needs to be set in the waiting area to attract the bird to walk back to the waiting area before the next round of training can be started. This design method will increase the training time per round because the bird needs to move back and forth, reduce the training efficiency, and also introduce motion noise, reducing the signal-to-noise ratio of the electroencephalogram signal. Third, the electric control gate located in the middle of the observation area and the selection area is extremely likely to cause the bird to appear in the wrong position due to slow closing or opening speed, or insensitive infrared induction, etc., resulting in the training getting stuck and unable to proceed, and manual reset is required. Fourth, setting the reward food box at the ends of the two channels will speed up the bird's satiety speed, reduce the number of trainable times, and because the waiting area is an unconditional food box, it will cause the bird's laziness, making it more difficult to improve the training accuracy rate; Fifth, the bird needs to observe the display screens at the ends of both arms simultaneously, and it is difficult to achieve a single target stimulus when performing tasks such as sample delay matching. Moreover, due to the bird's right-eye dominance (such as pigeons), the double screens will bring certain preferences to the bird's selection, resulting in unqualified training effects.

Specific embodiments

[0023] To facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present invention more thorough and comprehensive.

[0024] It should be noted that unless otherwise defined, the technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention.

[0025] An embodiment of a training device for a bird vision binary classification task of the present invention is as Figures 3 - 4As shown, it includes a training box 1. The training box includes a first cavity 3 at the rear and a second cavity at the front that is connected to the first cavity. The first cavity 3 is for putting birds in to form an observation area A. The size of the first cavity is smaller than that of the second cavity, and the size can be set according to actual needs. A transparent partition 20 is provided in the second cavity to divide the second cavity into an installation cavity 28 and a transition cavity in the front-rear direction. A display screen 5 is provided in the installation cavity directly in front of the first cavity. Specifically, the training box includes a rear side plate 22, a first left side plate 23, and a first right side plate 24. The space among the rear side plate, the first left side plate, and the first right side plate forms the first cavity, that is, the observation area A. The training box also includes a second left side plate 26, a second right side plate 27, a front side plate 25, a first inclined plate 29 connecting the first left side plate and the second left side plate, and a second inclined plate 30 connecting the first right side plate and the second right side plate. The space among the second left side plate, the second right side plate, the front side plate, the first inclined plate, and the second inclined plate forms the second cavity. The transparent partition, the second left side plate, the second right side plate, and the front side plate form the installation cavity, and the space between the transparent partition and the first inclined plate and the second inclined plate forms the transition cavity. The transparent partition can not only let the birds see the content of the stimulating pictures on the display screen, but also prevent the birds from running around randomly. The upper end of the training box is open and is equipped with an upper cover plate 2. The upper cover plate can reduce the brightness inside the training box, create a low-light environment, make the images on the display screen clearer, and can also calm down the birds.

[0026] A left baffle 6 is arranged on the left side of the first cavity in the transition cavity, and a right baffle 7 is arranged on the right side of the first cavity. The left and right baffles divide the transition area into a left cavity 31, a selection area B for bird activities located between the left and right baffles and communicating with the observation area, and a right cavity 32 from left to right in sequence. The bird is placed in the observation area, and the bird can move in the observation area and the selection area, restricting the bird within this range. In this embodiment, a left vibration induction switch 8 for the bird to peck is arranged in the left cavity, and a right vibration induction switch 9 for the bird to peck is arranged in the right cavity. Specifically, both the left vibration induction switch and the right vibration induction switch are arranged on the transparent partition board. In this embodiment, the purpose of arranging the left and right baffles is that the left and right baffles can block the bird's body from entering the left and right cavities, but the bird's head and neck can cross the left and right baffles to enter the left and right cavities to peck the corresponding vibration induction switches, reducing the movement of the bird during the training process, thus reducing the noise caused by the movement and saving the time consumed by the bird's multiple runs. To prevent the bird from accidentally pecking the vibration induction switch when not stimulated by the image, a left movable baffle 10 for blocking the left vibration induction switch to prevent the bird from accidentally pecking is arranged in the left cavity, and a left movable baffle driving mechanism 11 is arranged in the left cavity. A right movable baffle 12 for blocking the right vibration induction switch to prevent the bird from accidentally pecking is arranged in the right cavity, and a right movable baffle driving mechanism 13 is arranged in the right cavity. Specifically, both the left movable baffle driving mechanism and the right movable baffle driving mechanism adopt servo motors, and the servo motors drive the corresponding movable baffles to flip to prevent the vibration induction switch and to give way to the vibration induction switch.

[0027] A reward food box 21 is provided in the selection area. The reward food box is used to feed the birds as a reward when they make the correct choice. In this embodiment, the reward food box includes a mounting bracket 14 provided in the selection area. A feeding trough 15 is rotatably provided on the mounting bracket, and a feeding trough driving mechanism 16 for driving the feeding trough to rotate is provided on the mounting bracket. The feeding trough driving mechanism also uses a servo motor. The feeding trough has an open position for the birds to feed after rotation and a closed position for blocking the birds from feeding after rotation. A camera 17 capable of shooting the training process of the birds is provided in the training box. In this embodiment, the camera is provided above the observation area and shoots downward and forward. Setting the reward food box in the selection area has the advantage that after the head and neck of the bird cross the corresponding baffle and peck the corresponding vibration induction switch, they must retract the head and neck to eat the food in the feeding trough, and the next training can be directly started. In addition, there is no need to set an unconditional food box to lure the birds back as in the background art, which can greatly reduce the training time per round and increase the number of training times. Moreover, the feeding trough is rotatably provided. Only when the bird makes the correct choice, that is, pecks the vibration induction switch in the correct direction according to the image stimulus on the display screen, will the feeding trough rotate and open for the birds to feed, otherwise the feeding trough will not open. A high-frequency sound generator can be selected to be provided in the training box as a punishment for the birds after they make a wrong choice.

[0028] The training device further includes a host computer 18, which can be a PC. The host computer is connected to a display control module, a video recording module, and a training record module. The display control module is connected to the display screen and controls the switching of image types, the control of display time, the turning off and on of the screen, as well as the split-screen display, the display area, and other controls of the display screen. The video recording module is connected to the camera and controls the power-on and power-off of the camera. The training record module is used to record training information, which includes information such as the types of stimulus pictures, the selection of birds, the correct rate, and the pecking key time. The host computer is connected to a slave computer 19, which can be a single-chip microcomputer. The slave computer is connected to the left vibration induction switch and the right vibration induction switch and is used to collect the information that the vibration induction switch is pecked. For example, after the bird pecks, a high level will be returned to the slave computer. The slave computer is connected to the food trough driving mechanism and can control the rotation of the food trough and reward the bird to peck the food in it after the bird makes a correct selection. Then, it controls the food trough to turn back. The opening time of the food trough can be controlled according to the set time, such as 5 seconds, to prevent the bird from pecking continuously and causing training laziness. The slave computer is connected to the left movable baffle driving mechanism and the right movable baffle driving mechanism and can prevent the bird from pecking by mistake. After the stimulus image is displayed on the display screen for a certain time, such as 3 seconds, the slave computer can control the left movable baffle driving mechanism and the right movable baffle driving mechanism to open the corresponding vibration induction switch for the bird to choose to peck. After pecking, within a certain time, such as 0.5 seconds, the movable baffle can be controlled to block the corresponding vibration induction switch. The slave computer is also connected to a pulse marking module, and the pulse marking module is connected to the electroencephalogram signal acquisition and analysis device. After the bird selects the corresponding vibration induction switch to peck, the pulse marking module will generate a high-level signal and send it to the electroencephalogram signal acquisition and analysis device, and generate punctuation marks in the continuous electroencephalogram signal to facilitate the subsequent extraction of useful signal segments. The electroencephalogram signal acquisition and analysis device belongs to the prior art and will not be introduced in detail in this embodiment. The host computer and the slave computer are connected through a serial port. In this embodiment, the serial port is connected by a USB serial data cable for communication and power supply.

[0029] During use, place the bird in the observation area, cover the upper cover plate to create a low-light environment and calm the bird down. Power on the lower computer, start the camera for recording and the training program of the upper computer. The types of stimulation pictures, the control algorithm of stimulation pictures, and the number of training times will all follow the default settings. At this time, training information such as the bird number and training type needs to be input to generate a training record. According to the settings of the upper computer, the display starts to show stimulation pictures, which can show a single stimulation target or show multiple stimulation targets in split screens for the bird to choose. After the stimulation ends, rotate the movable baffle to open and expose two vibration induction switches for the pigeon to make a choice according to the stimulation situation. The left and right baffles enable the bird to only cross the head and neck to peck the key without being able to leave the selection area. If the choice is correct, the food trough will open, and the bird must retreat to the observation area or the selection area to eat the food, so there is no need to set up an unconditional food box to lure the bird back, which can greatly reduce the training time per round, increase the number of training times, and improve the training efficiency. After the bird pecks, both movable baffles will close in time, the stimulation pattern will disappear, and at the same time, the upper computer will record the training information of this round and start the next training.
