This article cites Day4 Results in the literature , It is speculated that the reason why time has a greater impact on space is that space-time interference is affected by task difficulty ( It is consistent with my guess after reading ), It can be read in combination .

List of articles


Abstract

1、 The asymmetry of spatiotemporal interference is affected by the significance of related stimuli ;

2、 When space tasks are more difficult than time tasks , The influence of time on space is greater than that of space on time , The relationship between spatiotemporal interference is asymmetric .


One 、 Preface

1、 Two theories of spatiotemporal interference relations :ATOM( symmetry )vs Metaphor theory( Asymmetry ), See Day3 The literature .

2、 Previous studies have mostly balanced the difficulty of the experiment , But it may affect whether the stimulus is easily recognized by perception , Therefore, this paper believes that difficulty will have an impact on the relationship between time interference .

3、 This article uses saliency saliency To describe the degree to which a stimulus can be recognized , Use task difficulty task difficulty To describe the difficulty of completing the experimental task : Task related stimuli saliency The bigger the task difficulty The smaller it is , Task unrelated stimuli saliency The bigger the task difficulty The bigger it is .

4、 Research ideas : Explore when space tasks are more difficult than time tasks , Whether time has a greater impact on space ?


Two 、 Experimental design

24 Subjects participated in 2( Task type , Time interval / The line length is relatively long )×2( Line length range ,140-152/170-182 pixels) In subject experiment design . During the time interval judgment task , Thread length ( Unrelated dimensions ) In short 、 in 、 Change on three levels , To explore cross dimensional impacts ( The influence of line length on time distance judgment ).

The experiment consists of three stages :

(1)Anchor Training: The subjects recognized the anchoring stimulus of time and space ( The shortest / Long ) Training for , Unrelated dimensional stimuli are fixed at intermediate values , Feedback .

(2)Bisection Testing: Subject judgment 5 The intermediate stimulus is longer than the anchored stimulus / Short training , Unrelated dimensional stimuli are fixed at intermediate values , Feedback . The data is taken as the baseline value without cross dimensional interference .

(3)Cross-Dimensional Testing: Subject judgment 5 The intermediate stimulus is longer than the anchored stimulus / Short training , Unrelated dimensional stimuli are random ( short / in / Long ), The data is a value that contains cross dimensional interference .


3、 ... and 、 experimental result

1、Task Difficulty

Task difficulty was measured by subjective scale , Together with the judgment error rate, it is analyzed as follows :

(1) For task difficulty : The main effect of task type is significant , The line length judgment task is difficult to judge the time interval task ; The main effect of line length range is significant ,170-182px It is more difficult under conditions ; The interaction between the two is not significant .

(2) For error rate : stay bisection and cross-dimensional testing in , The error rate of line length judgment task is significantly higher than that of time interval judgment task , It is consistent with the line length judgment task and the time distance judgment task ; The main effect of line length range is not significant , Then the line length range will not be discussed when exploring the task difficulty .

(3) The task difficulty and error rate are bisection and cross-dimensional testing Significant correlation in , See the picture below :

 2、Classification in Bisection Testing

Yes “ Long / short ” Reactive PSE The analysis shows that , The line length is accurate ( The geometric mean value falls in PSE Within the confidence interval ), The time interval judgment tends to be long response .

3、Classification in Cross-Dimensional Testing: the Main Results

 (1) The line leader judges the task , The main effect of uncorrelated dimensions is significant , And PSE Decrease as distance increases , Long term stimuli were judged to be longer , Time information has an impact on space tasks ;

(2) Time span judgment task , The main effect of unrelated dimensions is not significant ,PSE There is no linear change with the increase of line length , Spatial information has no significant effect on temporal tasks .

4、Reaction Time

The reaction time of space mission is bisection and cross-dimensional testing Are significantly longer than time tasks , Consistent with the more difficult results of space missions . But because the experimental variable involves the length of stimulus presentation , Therefore, reaction time is not suitable as a direct measure of task difficulty .

5、Slow and Fast Groups in RTs

According to the reaction time of each subject, they are classified as fast reaction / Two slow groups , Then, the size of the cross dimension impact on the spatial and temporal tasks of the two groups 、PSE Analysis of the situation shows that , The subjects with higher reaction speed may be more effective in ignoring the interference of irrelevant information .


Four 、 summary

1、 Spatiotemporal interference is affected by task difficulty . When the spatial judgment task is more difficult than the time judgment task , That is, the significant level of time stimulation saliency Higher , Time information has greater interference on space tasks , The relationship between time and space is asymmetric .

2、 The results of this paper are integrated with the maximum likelihood estimation model maximum-likelihood estimation (MLE) integration model Agreement , It controls the reliability of visual spatial information by controlling visual noise .

3、 This paper considers that the automation of processing processing automaticity( The higher the degree, the faster the reaction ) And memory can affect cross dimensional interference .

4、 Although the result of this paper is that time has a greater impact on space , But that was achieved on the rare premise of manipulating space missions ( If you manipulate the time task difficulty, you may get the opposite result ), Because this article supports the symmetric space-time relationship ATOM Theory, not metaphor.
