Effects Of Disturbed Presentation On Visual Working Memory: The Role Of Punishment And Reward

Visual working memory is used to describe the storage and processing of target information in visual memory,we perceive the spatial position of objects,better concentration,and play an important role in our cognitive behavior.In our daily life,there are often situations where we need to pay attention to the target information at the same time and suppress the interference of irrelevant information,so in order to have a more comprehensive understanding of the ability of visual working memory to grasp the surrounding information,it is particularly important to study the mechanism of discrimination and interference of information nature.Visual memory has limited storage and processing capacity and is influenced by numerous factors.Studies have found that visual working memory capacity increases when stimuli are associated with each other.In terms of the influence of working memory capacity on visual working memory,it is found that the expected cue effect can improve the accuracy of the final visual working memory task without affecting the overall resource call,so is such a capacity limit still 3～4 of the general memory capacity when the nature of the cue role is different? It is not yet clear.And studies have shown that negative items attract our attention more than neutral and positive items,so does interference have different effects when there are multiple high-value items in the same place,and there are two types of rewards and punishments(and different value intensities)? In view of the above problems,this experiment will mainly discuss the prompts of the nature of rewards and punishments,and how the accuracy of visual working memory will change when there is suffix interference.Experiment 1a based on Allen(2018),using a more differentiated value position differentiation in order to better observe the capacity changes and interference effects caused by the value difference,and the results show that we still pay more attention to the reward position than the neutral position,and the interference also affects the final memory efficiency.According to Thorndike’s "law of effect",repeating the previous reaction,we will have a tendency to reward and eliminate those that follow punishment,and more high-value items will take up our attention resources,so in experiment 1b we increase the number of high-value locations to detect whether the contrast between high-value positions and neutral positions increases as the number of high-value intensities increases,and whether interference has a significant effect in it.The results show that after increasing the number of high values,the difference between the two types of positions further increases,and interference has an obvious role in it,but such an effect exists independently of the location nature.Experiment 2a We added a penalty position to the type of high-value position,first we added a punishment position,observed what type of tendency the participant had to their memory goals when the reward intensity was greater,experiment 2b we reversed the intensity value of reward and punishment,added two punishment positions,and only one reward position remained at this time.If we find that compared to two penalty positions,one penalty position will cause us to pay more attention and lead to better visual working memory accuracy,then it means that we will have a better memory effect when the number of higher value intensity(that is,penalty position)is less,and if the effect of interference is still independent of location at this time,then it means that more types of memory in the memory stage and longer time will dilute the correlation between our visual working memory and the nature of the previous memory item.After observing the distinction in the number of high-value positions in experiment 2,in order to further balance the influence of high-value rewards,supplementing the results of experiment 2,we set up experiment 3,removed the neutral position,divided the number of reward positions and punishment positions equally,and observed the effects of punishment position and reward position on visual working memory,which further verified the difference between high-value positions in visual working memory and the influence of interference.It is found that when the penalty position is the same number as the reward position,the correct rate of the penalty position is significantly higher than that of the reward position,and the interference has the greatest difference when it is detected as the penalty position,but this difference is independent of the position change.In summary,this study mainly explores the difference in the influence of highvalue memory targets of different properties on visual working memory when the distribution is uneven,and the effect of stimulus suffix interference in such conditions.Future studies can further explore this issue from the perspective of interference location and electrophysiology.
