Bereaved parents means that one or more children accidental dead for violence, natural disasters and other emergencies, and refers to the symptoms of disease, emotional problems and social function defect caused by the bss of children, bereaved parents is one of the most concerned in bereavement research group. In recent years, bereaved parents become a new research point in China. Based on the1.34billion populations, bereaved parents are a special group of considerable. Statistical data show that in2013by Wang Guangchuan, there are nearly one million families had ever born but lost their children, and the woman’s age was over35in2010, this data does not include those bereaved women below35years old. Population experts Yi Fuxian inferences that there are ten million bereaved families in China., Sichuan Province population Department statistics that more than ten thousand bereaved family lost their children in Wenchuan earthquake of "5.12", and because of the loss of their loved child suddenly, they are unable to accept the reality, has been hit in the psychological and physiological, and their family relationship and structure was destroyed, the trauma of the lose can not be restored for a long time, and it results in individuals suffering from mental illness, and even some people lose their desire to live. In addition to psychological trauma, social comfort and support of bereaved parents has become a social problem.Although bereaved groups bear double pressure in psychological trauma and loss of social status, but the domestic research for the bereaved person is not too much. As the research number, from1980to2013, there are46chapters in the main database of domestic research in the "bereavement" as the theme. And the43studies in son lose. And the research of the lose the signal child as the theme raised from2012,and exploded in2013, reached99chapters. From the research content, it mainly related to demographic, political science, sociology, medicine, law, media and other fields. But Research in psychology is few, and the published articles mainly research from psychiatry, nursing and social work perspective. And from the research methods, they mainly uses the qualitative studies, questionnaire survey, experimental research rarely.Form the psychic trauma experimental research, Wang Man had been put forward that attentional bias in recent years was shown to be the cause of some mental disease, maintenance and recurrence. Attentional bias means that some traits of individual acceptance of certain external stimuli, a kind of attention preference to keep information related to high sensitivity and priority processing to certain stimuli, in essence, it is a kind of selective attention, which can be decomposed into multiple components, such as attentional facilitation, attentional avoidance, attentional disengagement. Domestic and foreign traumatic events lead to post-traumatic stress disorder (PTSD), complicated grief (CG) patients and a variety of depression (MinD, MDD, DD) in patients, a lot of studies have shown that negative patients owns attention bias in negative stimulus, the effect of traumatic events on the individual continued for a few years or even decades of time. But unanimous conclusion fails to get with different paradigm. And the conclusion is different for different types of bereaved group.China culture always pays attention to the importance of family. The word "national" is the typical state characteristics of social development. In the situation of bereaved family gradually become a social concern realistic background and the relevant theoretical research deficiency, based on foreign studies and domestic on posttraumatic stress disorder to the bereaved attention, anxiety disorder, negative body image individual attentional bias for the experimental research, This thesis starts from the perspective of Wenchuan earthquake bereaved parents, with a lot of relevant literature and using behavioral experiment method to study the attentional bias of Wenchuan earthquake bereaved family. and studies the differences of attentional bias from these two groups. The study included two experimental designs.(1) The first experiment adopts Emotional Stroop Paradigm to study the the attention bias of the bereaved parents in Wenchuan earthquake who rearing again and who did not, and the differences between the two groups.(2) The second experiment adopts Dot Probe Paradigm with matched neutral expressions to get a further understanding to the attentional bias mechanism of the two groups. To dig out their behavior is the attentional facilitation or attentional disengagement. Whether the compositions of them are same or notThe mian conclusions are as follows: (1) In the Emotional Stroop Paradigm, both of them have attentional bias on the negative words of the earthquake and bereavement, and give the prior attention to the negative stimulus of the earthquake and bereavement.(2) In the Emotional Stroop Paradigm, the parents who did not give birth again get more interference effect than the parents who did from the negative stimulus of the earthquake and bereavement.(3) In the Dot Probe Paradigm with matched neutral expressions, the parents who did not give birth again appear attentional disengagement, while the parents who give birth again do not appear like that.
