【摘要】:對(duì)甜食線索的注意偏向是指相對(duì)于中性線索或低能量食物線索,個(gè)體對(duì)甜食線索的選擇性注意,具體表現(xiàn)為對(duì)甜食線索的定向、維持或回避。對(duì)甜食線索的注意偏向訓(xùn)練是指通過一系列訓(xùn)練調(diào)節(jié)個(gè)體對(duì)甜食線索的注意增強(qiáng)或注意減弱。本研究在已有相關(guān)研究的基礎(chǔ)上,采用行為學(xué)研究方法探討了女大學(xué)生對(duì)甜食線索的注意偏向,并嘗試采用新的注意偏向訓(xùn)練方法——眼跳訓(xùn)練任務(wù)探討對(duì)甜食線索的注意偏向訓(xùn)練效果。實(shí)驗(yàn)一采用空間線索提示范式,以對(duì)探測刺激的反應(yīng)時(shí)為因變量,探討相對(duì)于低能量食物線索及中性線索,女大學(xué)生對(duì)甜食線索是否存在注意偏向,及線索呈現(xiàn)時(shí)間為200ms和500ms時(shí)注意偏向的成分。被試為鄭州大學(xué)女大學(xué)生52名,BMI指數(shù)均位于18.50-24.99之間(正常體重)。采用2(線索呈現(xiàn)時(shí)間:200ms;500ms)x 2(線索類型:中性圖片;低能量食物圖片;甜食圖片)x 2(線索提示類型:有效線索;無效線索)的混合實(shí)驗(yàn)設(shè)計(jì)。實(shí)驗(yàn)二運(yùn)用眼動(dòng)研究,以對(duì)甜食線索的首視點(diǎn)定向偏向分?jǐn)?shù)、首視點(diǎn)注視時(shí)間偏向分?jǐn)?shù)及總注視時(shí)間偏向分?jǐn)?shù)為因變量,利用Fixation Trigger控件探討眼跳訓(xùn)練任務(wù)(朝向眼跳訓(xùn)練任務(wù)和反向眼跳訓(xùn)練任務(wù))是否可以改變被試對(duì)甜食線索的注意偏向。采用2(測量階段:前測;后測)x 2(偏向訓(xùn)練條件:趨向甜食組;回避甜食組)的混合實(shí)驗(yàn)設(shè)計(jì)。實(shí)驗(yàn)一結(jié)果表明,有效線索條件下,線索呈現(xiàn)時(shí)間為200ms時(shí),被試對(duì)以甜食圖片為線索的探測刺激的反應(yīng)時(shí)顯著小于以中性圖片及低能量食物圖片為線索的探測刺激的反應(yīng)時(shí),對(duì)以低能量食物圖片與以中性圖片為線索的探測刺激的反應(yīng)時(shí)沒有顯著差異;無效線索條件下,當(dāng)線索呈現(xiàn)時(shí)間為500ms時(shí),被試對(duì)以甜食圖片為線索的探測刺激的平均反應(yīng)時(shí)顯著大于以中性圖片及低能量食物圖片為線索的探測刺激的平均反應(yīng)時(shí),對(duì)以低能量食物圖片與以中性圖片為線索的探測刺激的反應(yīng)時(shí)也沒有顯著差異。實(shí)驗(yàn)二結(jié)果表明,回避甜食組經(jīng)過反向眼跳訓(xùn)練后對(duì)甜食線索首視點(diǎn)注視時(shí)間及總注視時(shí)間偏向分?jǐn)?shù)的顯著減少,而首視點(diǎn)定向偏向分?jǐn)?shù)沒有顯著變化;而趨向甜食組經(jīng)朝向眼跳訓(xùn)練后對(duì)甜食線索的首視點(diǎn)定向及首視點(diǎn)注視時(shí)間偏向分?jǐn)?shù)顯著地增加,總注視時(shí)間偏向分?jǐn)?shù)沒有發(fā)生顯著變化。通過對(duì)結(jié)果的分析,得出如下結(jié)論:(1)相對(duì)于低能量食物線索和中性線索,被試對(duì)甜食線索注意偏向特點(diǎn)都表現(xiàn)為注意定向-維持模式。200ms時(shí)表現(xiàn)為對(duì)甜食線索的注意定向,500ms時(shí)表現(xiàn)為對(duì)甜食線索的注意維持;而相對(duì)于中性線索,并不存在對(duì)低能量食物線索的注意偏向。(2)眼跳訓(xùn)練任務(wù)能夠有效地調(diào)節(jié)女大學(xué)生對(duì)甜食線索的注意偏向。其中,反向眼跳訓(xùn)練降低對(duì)甜食線索的早期階段和總注意維持,主要是增強(qiáng)了女大學(xué)生對(duì)甜食線索的注意解除能力;朝向眼跳訓(xùn)練不僅增加了對(duì)甜食線索的注意維持,還可能增加對(duì)甜食線索的注意定向。
[Abstract]:The attention bias to sweet cues refers to the selective attention of the individual to the sweet cues relative to the neutral clue or the low energy food clue. The specific expression is the orientation of the sweet cues, the maintenance or avoidance of the sweet clues. The attention bias training for the sweet clues refers to the enhancement or attentional attendant of the sweets clue through a series of training. On the basis of relevant research, the study explored the bias of female college students' attention to sweet food clues by behavioral study methods, and tried to use a new attention bias training method, the training task of saccade training, to study the effect of attention bias on sweet food clues. The reaction time was dependent on the dependent variable, and compared with the low energy food clues and neutral clues, the female college students had attention bias to the sweet food clues, and the clue presentation time was 200ms and 500ms. The 52 female college students in Zhengzhou University, the BMI index in the 18.50-24.99 (normal weight). Present time: 200ms; 500ms) x 2 (clue type: neutral picture; low energy food picture; sweet food picture) x 2 (clue type: effective clue; ineffective clue) mixed experimental design. Experiment two use eye movement study to determine the orientation bias score of the first view point of the sweet food clue, the first view fixation time bias and the total fixation time bias. For the dependent variable, the Fixation Trigger control is used to explore whether the saccade training task (toward the saccade training task and the reverse saccade training task) can change the attention bias of the subjects on the sweets cues. 2 (measurement stage: pre test; post test) x 2 (bias training conditions: tendency to dessert group; avoidance of dessert group) The results showed that when the cue presentation time was 200ms, the response of the subjects to the detection stimulus with the sweet picture as a clue was significantly less than the response to the detection stimulus with the neutral picture and the low energy food picture as a clue. There were significant differences; under the condition of ineffective clues, when the time of clue presentation was 500ms, the average response of the subjects to the detection stimulus with the sweet picture as the clue was significantly greater than the mean response to the neutral picture and the low energy food picture as the clue. The results showed that there was no significant difference in the reaction time. Experiment two showed that the dessert group after the reverse saccade training had a significant decrease in the fixation time of the first sight and the total fixation time, while the orientation of the first view orientation did not change significantly. The orientation and the first view fixation time bias increased significantly, and the total fixation time bias did not change significantly. Through the analysis of the results, the following conclusions were obtained: (1) compared with the low energy food clues and neutral clues, the attention bias characteristics of the dessert cues were all manifested by the attention orientation maintenance model.200ms. Attention orientation for sweet food clues, 500ms displayed as the attention to the attention of the sweet clues; and relative to neutral clues, there is no attention bias to low energy food clues. (2) saccade training tasks can effectively regulate female college students' attention bias to sweet food clues. The segment and the maintenance of the total attention are mainly to enhance the ability of the female college students to dissolve the sweets' clues. The orientation of the saccade training not only increases the attention to the sweet clue, but also increases the attention orientation of the sweet cues.
