1920s，Western psychologist Zeigarnik conducted a memory experiment: she asked each subject to do 20 designated bet365 horse racing odds，Half of the work is allowed，The other half were interrupted before the subjects finished。Result display，The subjects’ recall rate of unfinished work reached 68%，Only 43% of completed work can be recalled。It can be seen from this，People tend to remember unfinished or interrupted bet365 horse racing odds better than completed bet365 horse racing odds，This is called the Chiconi effect or Zeigornik effect in psychology。

Such examples are not uncommon in real life，If a girl doesn’t buy the dress she likes when she goes shopping，I will never forget this dress when I get home，I regret not buying it；If work or study matters are not completed，It will affect the weekend rest...We are always more impressed by things we can’t get or haven’t done yet。Cai Gornik thinks，This difference is mainly due to the difference in unfinished bet365 horse racing odds，And this memory advantage comes from a need to complete the task。

Psychologist Atkinson believes，The Chiconi effect is related to achievement motivation，In achievement-motivated situations，Individuals with high achievement motivation have better memory for unfinished bet365 horse racing odds than those with low achievement motivation。American psychologist Bernard Weiner and others investigated this hypothesis in real-world achievement settings，Divide students into high、中、Low different motivation group，After the final exam，Require students to recall test content。Experimental results display，The Chiconi effect is highly correlated with the intensity of outcome motivation，Mainly manifested in individuals with high achievement motivation，is caused by differences in recall of unfinished bet365 horse racing odds。However，Different recollections do not necessarily reflect differences in memory，Caron and Wallach have shown that the Chicconi effect is due to differential learning rather than differential memory。To show differences in event memory，Must maintain equality in the degree of original learning materials。If students learn more about unfinished bet365 horse racing odds than completed bet365 horse racing odds，Then their memory of these bet365 horse racing odds will also be different。Weiner summarizes some research，Suggests that individuals high in achievement motivation are attracted to bet365 horse racing odds in which they initially fail。Opposite，Individuals with low achievement motivation will especially avoid failure or bet365 horse racing odds that they cannot complete，Therefore they are less likely to repeat and remember these items in private，But students with high outcome motivation are more motivated to learn from unfinished bet365 horse racing odds than students with low outcome motivation，They may study the unfinished bet365 horse racing odds privately。This analysis shows，If the individual is not allowed to recall failed bet365 horse racing odds，Then the Chiconi effect will not be shown。

However，Unfinished work can also bring pressure to our life and study。Everyone knows，Work or study pressure can affect sleep quality。Christine et al. studied the relationship between unfinished work and employee weekend sleep through observation diaries，They use unfinished bet365 horse racing odds as the key to employees’ meditation，Revealing the mechanism behind it。Researchers conducted diary observations of 59 employees for 12 weeks，And compared on Friday and Monday，The results show，The relationship between unfinished bet365 horse racing odds and sleep is mediated by affective rumination。Affective rumination is a cognitive state，Contains negative emotions and is destructive、ubiquitous、Recurring work ideas。It is distinguished from problem-solving pondering，The latter is a long-term reflection on a specific problem or previous work，Include how to fix or improve it，But does not involve the negative emotional processes characterized by emotional rumination。In addition，The number of unfinished bet365 horse racing odds for more than 3 months has a greater impact on employee sleep than unfinished bet365 horse racing odds in the acute phase，That is, the more bet365 horse racing odds that have not been completed for more than 3 months，The greater the probability of impaired sleep on weekends。

Therefore，To reduce the impact of work or study stress on health，Breaking bet365 horse racing odds into subtasks or subgoals will improve our work efficiency。Another challenge employees face is thoughts that are not work-related。To avoid emotional rumination，Hahn et al. proposed training to learn how to recover from work stress。During training，Used the four healing experiences proposed by Sonnentag and Fritz: psychological detachment、Relaxation、Mastery experiences and control。Psychological detachment refers to being mentally detached from work，Mental shutdown can keep you away from work-related thoughts；Relaxation refers to the psychological experience associated with low sympathetic activation，Other relaxation practices such as meditation；Experience gained includes experience related to challenge and learning，Typical examples include sports、Study activities or volunteer work，Relaxation and experiences gained outside of work produce positive emotional states，Supplement individual emotional resources。Control refers to the experience of autonomy，After work，It allows people to spend their time on activities that best suit their personal preferences，And reduce activities that are stressful or inconsistent with personal goals。
