Description

Technical Field

[0001] The invention relates to the technical field of bird vision training, and in particular to a bird vision cognition training system and method based on pecking behavior. Background Art

[0002] Birds are often used as model animals for visual cognition training because of their excellent visual ability. At present, pecking or pecking is generally used to provide feedback on birds' decision-making behavior during visual cognition training. WJ Clark et al. used an infrared touch screen in "Searching for Face-Category Representation in the Avian Visual Forebrain" to train pigeons to peck at different areas of the screen to reflect the corresponding decision intentions; Niu Xiaoke et al. trained birds to peck at a resistive touch screen in "Bird Visual Cognition Learning Training System" to record their decision-making behavior; A. Nieder et al. trained crows to learn to peck at different target images on a capacitive touch screen according to different prompts in "Abstract rule neurons in the endbrain support intelligent behavior in corvid songbirds" to master the corresponding corresponding rules; Shang Zhigang et al. trained pigeons to feedback related cognitive behaviors by pecking at a touch-sensitive push switch in "Learning Training System for Animal Group EEG Synchronization".

[0003] In summary, in the current bird visual cognition training system, the touch screens commonly used when using the pecking scheme are mainly capacitive, resistive and infrared. Among them, the infrared touch screen has a complex structure and is easy to be touched by mistake, and the behavior result detection effect is not ideal; the beaks of birds are usually sharp and hard, and capacitive and resistive touch screens often fail to function in some areas of the screen due to pecking in long-term use, which also leads to excessively high screen costs. When using the pecking scheme, birds are usually trained to peck at light-touch push switches, but in visual cognition tasks, the target is usually presented on the display screen, and the pecking scheme requires the behavioral feedback to be transferred from the screen to buttons in other locations, which brings a certain degree of process complexity and is not conducive to the visual cognition training of birds. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a bird visual cognition training system based on pecking behavior, so as to solve the problems in the prior art that the pecking scheme requires the replacement of the touch screen, resulting in high training costs, and low efficiency of passive training of the trainees, and to achieve the advantages of simple training system structure, low cost, and autonomous training of the trainees with high efficiency.

[0005] After long-term experiments, the inventors found that most of the current bird visual cognition training systems do not repeat incorrect trials, but only play a group of stimuli in a set order. This cannot strengthen the birds' learning of the stimuli presented in incorrect trials, and it is difficult to consolidate the corresponding rules, resulting in low training efficiency; and the existing bird visual cognition training systems usually start a trial manually or through a set program. These non-bird-autonomous starting methods will cause the birds to be unable to concentrate on observing the presented stimuli when the birds have not entered the task state, thereby causing a waste of trials and inefficient training.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] like Figure 1-Figure 5As shown, a bird visual cognition training system based on pecking behavior according to an embodiment of the present invention includes a box 10, a first display 20, a behavior feedback module 30, a reward and punishment module 40, a lower computer system 50 and an upper computer system 60; the first display 20 is arranged in the box 10 to display visual stimulation for the training target; at least one behavior feedback module 30 is arranged on the first display 20, and the behavior feedback module 30 includes a transparent plate 31, an elastic connector 32 and a micro switch 33, the transparent plate 31 is arranged on one side of the front of the first display 20, one end of the elastic connector 32 is connected to the first display 20, and the other end is connected to the transparent plate 31, the fixed end of the micro switch 33 is connected to the first display 20, and the trigger end faces the transparent The plate 31 is arranged so that the micro switch 33 is triggered when the transparent plate 31 moves toward the first display 20; the reward and punishment module 40 includes a generator 41 for noise punishment on the trained target and a feeding box 42 for time-limited feeding of the trained target; the lower computer system 50 is electrically connected to the behavior feedback module 30 to receive the behavior information of the trained target, and the lower computer system 50 is electrically connected to the reward and punishment module 40 to control the reward and punishment module 40 to punish or reward the trained target according to the behavior information; the upper computer system 60 is electrically connected to the first display 20 and the lower computer system 50 respectively to receive the behavior information of the trained target, and control the first display 20 to display visual stimulation to the trained target according to the behavior information, and control the position, number and category of the visual stimulation.

[0046] In the specific embodiment of the present invention, a plurality of behavior feedback modules 30 are provided on the first display 20. A training trial is initiated by the trainee autonomously pecking at one of the behavior feedback modules 30, thereby realizing autonomous training of the trainee. The reward and punishment module 40 provided in the box 10 is used to reward the correct behavior information of the trainee for a limited time, thereby strengthening the training degree of the trainee for visual stimulation and improving the training effect. In the specific embodiment of the present invention, a transparent plate 31 is provided in parallel on the front of the first display 20, thereby reducing the usage of the touch screen, thereby reducing the cost caused by the replacement of the touch screen. The top of the first display 20 is connected to the top of the transparent plate 31 by an elastic connector 32, thereby realizing the connection between the first display 20 and the transparent plate 31, and facilitating the transparent plate 31 to move toward the first display 20. In the specific embodiment of the present invention, the host computer system 60 controls the first display 20 to display visual stimulation to the trainee according to the received behavior information, and controls the position, number and category of the visual stimulation. The same visual stimulation is repeatedly reproduced for the wrong behavioral decision of the bird, thereby strengthening the learning of the bird for any stimulation and greatly enhancing the training effect.

[0047] Optionally, the behavior feedback system further includes a camera 70 and a second display 80 electrically connected to the host computer system 60, respectively. The camera 70 is arranged above the top opening of the box 10 to record the training process of the training target, and the second display 80 is used to display the real-time training status of the training target. Such a setting can not only monitor the training status of the bird in real time and record the video for subsequent in-depth analysis of the training video, but also facilitate the operator to observe the real-time training status of the bird and operate the human-computer interaction software to control the position, frequency and category of the visual stimulation on the first display 20.

[0048] Optionally, the box 10 is open at the top and made of wood, and its overall dimensions are: length*width*height 60cm*45cm*50cm. This arrangement can reduce the impact of the surrounding environment on the training target, and the training target has enough space for visual training.

[0049] Optionally, the behavior feedback module 30 further includes an elastic buffer 34, wherein a fixed end of the elastic buffer 34 is connected to the first display 20, and a movable end is disposed toward the transparent plate 31 and in contact with or forms a gap with the transparent plate 31. In this configuration, the impact of the transparent plate 31 on the micro switch 33 when it moves can be reduced through the buffering effect of the elastic buffer 34, thereby extending the service life of the micro switch 33.

[0050] Optionally, both the elastic connector 32 and the elastic buffer 34 are tower springs. Such a design is simple in structure and low in cost; it can not only give full play to the anti-interference ability of the spring as a flexible component, but also ensure a more reliable connection effect by its tower structure.

[0051] Optional, the detailed dimensions of the tower spring are: wire diameter 0.4mm, length 11mm, top diameter 6mm, bottom diameter 9mm, total number of turns 7; the material is spring steel.

[0052] Optionally, the large diameter end of the elastic connector 32 is connected to the top of the first display 20 through a nano tape, the small diameter end is connected to the top of the transparent plate 31 through a hot melt adhesive, and the large diameter end of the elastic buffer 34 is connected to the bottom of the first display 20 through the nano tape. This arrangement can make the connection between the elastic connector 32 and the elastic buffer 34 and the first display 20 more stable and reliable; the use of nano tape connection can ensure colorless and transparent, does not interfere with the display of the first display 20, and is easy to install and disassemble, and is convenient for expansion.

[0053] Optionally, there are two elastic connecting members 32. This arrangement is convenient for improving the stability of the connection between the first display 20 and the transparent plate 31, and ensuring that the micro switch 33 is triggered when the transparent plate 31 moves toward the first display 20.

[0054] Optionally, the number of the behavior feedback modules 30 is 2 to 6. With such an arrangement, modular assembly of the feedback system is achieved to meet different usage requirements, thereby expanding the application scope of the feedback system.

[0055] Optionally, the distance between the transparent plate 31 and the first display 20 is 10-12 mm. With such an arrangement, the transparent plate 31 can move toward the first display 20 under the action of an external force and trigger the micro switch 33 .

[0056] Optionally, the transparent plate 31 is a transparent acrylic plate with a size of 100 mm×100 mm and a thickness of 2 mm. This arrangement can ensure that the screen display is not disturbed and does not introduce additional factors that affect cognition.

[0057] Optionally, the reward and punishment module 40 also includes a baffle plate 43 and a drive motor 44. The baffle plate 43 is arranged close to the upper surface of the feeding box 42. The feeding box 42 is semicircular, and the center of the feeding box 42 is connected to the power output shaft of the drive motor 44. The drive motor 44 is electrically connected to the lower computer system 50, so that the feeding box 42 can be rotated in or out of the bottom of the baffle plate 43 under the drive of the drive motor 44. It is arranged in this way. The driving motor 44 drives the feeding box 42 to rotate, so as to realize the reward feeding of the trained target. That is to say, when the behavior information of the trained target is correct, the feeding box 42 is rotated out from under the baffle plate 43 to facilitate the trained target to eat; when the behavior information of the trained target is wrong, the feeding box 42 is located directly below the baffle plate 43, and the trained target cannot eat.

[0058] Optionally, the reward and punishment module 40 and the first display 20 are respectively arranged at the two ends of the inner cavity of the box body 10; such an arrangement enables the trained target to face the behavioral feedback module 30 directly when the trained target is being trained, and the feeding box 42 is located directly behind the trained target. When the trained target makes a correct behavioral decision, the feeding box 42 is rotated out, and the trained target turns around to get food. Setting the reward and punishment module 40 directly behind the trained target can avoid the situation where the reward and punishment module 40 generates a pecking bias towards the left or right behavioral feedback module 30 for the trained target in training when the reward and punishment module 40 is set on the left or right side of the trained target.

[0059] Optionally, the generator 41 is a speaker. In this way, a sharp sound with a frequency of 500 Hz is played to the training target as a warning punishment to improve the training effect, and the cost is low.

[0060] Optionally, the upper computer system 60 is mounted on a PC host and is a human-computer interaction software developed in VB language. The operator can use the software to set the position, duration, number of times and type of the visual stimulation pictures displayed on the first display 20, and can also change the corresponding behavioral feedback scheme as needed; at the same time, the behavioral information of the training target during the training process can be recorded, such as the time taken to complete a round of trials, and whether the behavioral decision in this round of trials is correct, etc. Such a setting has good operability.

[0061] Optionally, the lower computer system is a single-chip computer system, which communicates with the upper computer system through a USB interface. The single-chip computer system collects the potential signal of the micro switch 33 on the behavior feedback module 30 and controls whether to rotate the drive motor 44 to give food rewards to the trained target.

[0062] Working principle:

[0063] The trained target pecks at a certain behavior feedback module 30 at random, and the transparent plate 31 moves toward the first display 20 under the action of external force and triggers the micro switch 33. The upper computer system 60 receives the electrical signal (behavior information) sent by the micro switch 33, and controls the first display 20 to present different colors, graphics and other common stimuli for bird visual cognition to start a round of trial training. The trained target pecks the behavior feedback module 30 at the corresponding graphic position, thereby triggering the micro switch again. Through circuit connection, this potential signal can be transmitted to the lower computer system 50 to realize the detection of bird cognitive behavior feedback; the lower computer system 50 determines whether the behavior information of the trained target is correct (if yes, the drive motor 44 is controlled to drive the feeding box to rotate 180 degrees to provide the trained target with time-limited reward feeding. After the feeding time is over, the drive motor 44 is controlled to drive the feeding box to rotate another 180 degrees and hide under the shielding plate 43; if no, the generator 41 is controlled to impose noise punishment on the trained target).

[0064] A specific embodiment of the present invention also provides a bird visual cognition training method based on pecking behavior, comprising the following steps:

[0065] Step S1, pre-training; pre-training enables the training target to gradually complete the entire training process in a step-by-step learning manner to obtain the training target that meets the formal training; specifically includes:

[0066] Step S11, enables the trained target to establish an association between pecking action and food reward; the screen of the first display in step S11 is a gray screen, does not display any graphics, and does not display black blocks and white blocks. The trained target can obtain food rewards by pecking any behavior feedback module; the purpose of step S11 is to guide the trained target to learn the pecking behavior feedback module.

[0067] Step S12 enables the trained target to establish an association between pecking the decision option and food rewards; Step S12 requires displaying black blocks and white blocks corresponding to the behavior feedback modules on the first display, and the trained target can obtain food rewards by pecking any behavior feedback module corresponding to the black block or the white block; The purpose of step S12 is to guide the trained target from pecking the gray screen in step S11 to pecking the black blocks and the white blocks.

[0068] Step S13, enables the trained target to establish an association between stimulus picture - pecking the correct decision option - food reward; Step S13 requires first displaying a stimulus picture for visually stimulating the trained target on the first display, and then displaying black blocks and white blocks corresponding to the behavioral feedback modules on the first display. The trained target can obtain a food reward by pecking the behavioral feedback module corresponding to the visual stimulation during the behavioral feedback period.

[0069] Step S14, enables the trained target to establish an association between pecking behavior feedback module-stimulation picture-pecking correct decision option-food reward; specifically: the trained target autonomously pecks any behavior feedback module to start a round of trials, then the first display first displays the stimulation picture used to visually stimulate the trained target, and then displays black blocks and white blocks corresponding to the behavior feedback modules on the first display. The trained target can obtain food rewards by pecking the behavior feedback module corresponding to the visual stimulation during the behavior feedback period.

[0070] Step S20, formal training; the training target is trained in the following steps: autonomous pecking behavior feedback module start trial - stimulus picture - pecking correct choice option during behavior feedback period - food reward, until the training target's accuracy rate reaches 85% in 60 trials.

[0071] Optionally, in step S20, if the trained target makes an incorrect decision, the trial is repeated until the trained target makes three correct decisions in a row. In this way, the same visual stimulus can be repeatedly reproduced for the wrong decision of the bird's behavior, which can strengthen the bird's learning of any stimulus and greatly enhance the training effect.

[0072] By gradually adding preconditioning rather than sequentially adding steps in the training process, interference of decision option changes in the birds' training can be avoided.

[0073] like Figure 6 As shown, the functions of each time interval in the figure are explained as follows:

[0074] Inter-trial interval: used to separate different trials. During this period, the trained target can peck the behavioral feedback device autonomously to start a new trial. After the pecking is completed, the stimulus presentation period begins.

[0075] Stimulus presentation period: used to present different stimuli, and the duration can be set independently according to needs.

[0076] Delay period: After observing the stimulus picture, the trained target thinks about the next behavioral decision to be made during the delay period.

[0077] Behavioral feedback period: The trained target needs to complete the behavioral task corresponding to the stimulus seen previously during the behavioral feedback period. In this system, the trained target pecks the behavioral feedback module corresponding to the stimulus picture.

[0078] Reward and punishment period: Based on the correctness or error of the target behavior feedback, the reward and punishment module is driven to give food rewards or sound warnings to the target. At the same time, incorrect trials will be repeated to reinforce the bird's learning of the trial.

[0079] Compared with the prior art, the bird visual cognition training system and method based on pecking behavior in the embodiment of the present invention has at least the following advantages:

[0080] 1. This training system uses the physiological needs of birds for food. After the birds correctly complete the visual cognitive decision-making task, the feeding box is driven by the driving motor to feed food. The feeding time can be adjusted by adjusting the rotation time of the driving motor, which makes it easy to control the amount of food the birds eat each time. A correct behavioral feedback during the behavioral feedback period can be rewarded with food, and pecking the screen during the stimulus presentation period and the delay period will not be rewarded with food. When the bird's behavioral decision is wrong, the system will still present the same stimulus as the wrong trial in the next trial, until the behavioral feedback for the stimulus is correct three times in a row, and then a new stimulus will be presented in the next trial. This setting can strengthen the birds' learning of any stimulus and greatly enhance the training effect.

[0081] 2. This training system uses the bird's autonomous pecking of any behavioral feedback device to start a training trial, which helps to better train the birds to master the task rules, and at the same time can greatly improve the level of automation of training and greatly reduce the interference of human factors.

[0082] 3. The behavior feedback device used in this training system is expanded based on a common display screen. There is no need to purchase special touch screens such as infrared touch screens and capacitive touch screens, which greatly reduces the cost of the behavior feedback device for bird cognitive training, facilitates the development of scientific research related to bird cognitive training, and accelerates research in related fields. The components involved are all hardware components and are easy to obtain. The modular device has a simple structure, is easy to install and expand, and can be used in a variety of cognitive decision-making tasks without the need for additional device design. The trigger device uses a micro switch, which is easy to be triggered by bird pecking, and the behavior detection is reliable and has strong anti-interference ability.

[0083] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
