心 理學家相信,眼睛不會說謊。以往評估 戒毒成效,研究人員大多以問卷調查方 式,檢視戒毒者的狀態;不過,由於動機可能 過於明顯,參加者或會刻意掩飾自己的想法。 教大整全成長發展中心(I-WELL)打破常規, 首次採用「眼球活動追蹤」(eye-tracking)技 術,評估戒毒成效。這項技術,是以科學化方 式,觀察參加者的「第一眼」、視線停留及有否 重複瞄向同一張圖片,從而評估他們無法隱藏 的心癮。 I-WELL副總監、特殊教育與輔導學系教授(實 踐)梁智熊教授表示,其團隊曾利用眼球活動 追蹤技術,以一系列綜合測驗,量度自閉症兒 童辨認喜怒哀樂等面部情緒的能力。路德會青 欣中心曾委託教大進行為期三年的青少年戒毒 成效評估項目,梁教授便借助了同類技術,彌 補傳統手法之不足。他相信,比起檢驗頭髮或 尿液,採用眼球追蹤技術以了解青少年對毒品 的態度,對他們無疑多添一份尊重。 The eyes are windows to hidden thoughts 眼球追蹤 判別心癮 A s the expression goes, eyes don’t lie. Traditionally, researchers have assessed the progress of addiction treatment by reviewing questionnaires filled out by drug addicts, but the motive behind the questions is so obvious that the participants might conceal their true thoughts when they answer them. In a first for Hong Kong, the Integrated Centre for Wellbeing (I-WELL) of The Education University of Hong Kong (EdUHK) has adopted an eye-tracking technique for use in its assessment of the effectiveness of drug rehabilitation. Whatever catches the participants’ attention, whether they look at a particular picture repeatedly or whether their gaze fixes on something, is recorded and used to identify hidden addiction, if any, more scientifically. Professor Leung Chi-hung, Co-Director of I-WELL and Professor (Practice) of Department of Special Education and Counselling, has led his team to conduct a series of integrated tests employing eye-tracking techniques. The first application was a study to assess the ability of children with Autism Spectrum Disorder to associate various kinds of emotions with corresponding facial expressions. More recently, Cheer Lutheran Centre appointed EdUHK to conduct a three-year study to evaluate the effectiveness of a drug treatment programme for youngsters. EdUHK researchers formulated a series of tests that included eye tracking to complement conventional methods. Professor Leung believes the technique reveals youngsters’ proclivity towards drugs, but it shows more respect for their dignity, in contrast to substance abuse tests done with collected hair or urine. 02 ︱ Education-plus 超越教育 Feature 專題
