有鑑於台灣地區現今之區域發展型態，雖逐漸形成核心－外圍學說所稱之分散現象，然而就所得水準以觀，北部區域為東部區域之兩倍有餘，顯見區域間之差距依然過大;本研究乃因應產業東進策略及六年國建之區域均衡發展目標，探討東部區域歷年產業結構之變遷，旨在研提台灣東部區域未來之產業發展方向。 首先，對於產業東進策略而言，由空間發展策略來看，由於本區工業發展之基礎薄弱以及條件之不足，加上國家重要產業政策於本區之定位，本研究提出應開發當地資源，以促進區內發展，亦即“由下而上" ( From Below )的方式進行。 因此，有必要進一步分析本區產業發展之特性:由相對成長圖之分析，得知近期較具發 展基礎之行業為製造業及服務業;由區位商數可看出，製造業並非本區輸出基礎產業;再由移轉及分配分析可知，本區各項產業在空間之配置上集中於少數幾個大城鎮所在。此外，依據本區既有的產業發展基礎，並基於政府政策之考量，透過AHP 專家問卷的方式，進行產業東進發展策略之評選，得出以下結果:在所列的四項發展方式中，以高科技產業最為優先，其次為觀光服務業，再次為國防王業，最後才為地方資源型製造業。 最末，本研究參考上述結果，並且進一步考慮東部地區整體空間發展策略，配合本區發展條件與各項發展方式之特性及其於東部區域發展之可行性評估，本研究提出東部地區應優先考慮觀光服務業之發展。

本研究旨在探討不同聽力教學法對台灣國小學童聽力表現之影響，並試圖了解國小學童處理聽力之過程。本研究將七十六位國小五年級學童，其中包括五十二位男性與二十四位女性，分為「自下而上教學(bottom-up)」與「相互作用教學(interactive)」兩組，進行十五週之聽力教學。學童於聽力教學前後，均以劍橋兒童英檢初級(Starter Level)之聽力測驗進行前測與後測；同時，學童於每週聽力教學後，均須完成一份聽力小考，共計十五份。受試學童之前測、後測與十五次聽力小考皆以統計計量法加以計算，作為探討兩種聽力教學法成效之依據。此外，後測結束後，「相互作用教學(interactive)」組之學童接受問卷調查，以了解國小學童處理聽力之過程。 本研究主要發現「自下而上教學(bottom-up)」與「相互作用教學(interactive)」兩組之聽力表現並無重大差異。但整體而言，「相互作用教學(interactive)」組之平均分數較優於「自下而上教學(bottom-up)」組。問卷結果顯示，受訪之國小學童較常使用「由上而下」之訊息處理方式(top-down processing)，但大多數之受訪者表示，了解每一個單字的意義是聽力理解之關鍵因素。本研究最後提出若干相關建議以供參考。 / The purposes of this study were to identify effective teaching activities that improve elementary EFL students’ listening comprehension and to investigate when learners rely on top-down processing, bottom-up processing, and interactive processing. Participants in this study were 76 fifth graders from two classes in an elementary private school in Taipei County, including 52 males and 24 females. One of the two classes was treated with bottom-up pre-listening activities, while the other class was treated with interactive pre-listening activities. A pre-test and a post-test, adopted from the Starter level in the Cambridge Young Learners’ English Test, were implemented before and after a 15-week listening instruction. During the 15-week listening teaching, participants were also required to take a listening quiz after each session of teaching. Scores of the pre-test, post-test and the 15 listening quizzes were calculated by employing statistical measures to investigate the effectiveness of the two types of pre-listening activities, namely interactive and bottom-up pre-listening activities. Further, a questionnaire was administered for the interactive group after the post-test to investigate when learners relied on top-down processing, bottom-up processing and interactive processing. The major findings of the study are: first, results from participants’ listening scores revealed that there was no significant improvement between pre-test and post-test of the two groups although the mean scores of the interactive group were higher than that of the bottom-up group; second, results from the questionnaire indicated that participants employed top-down processing more frequently than bottom-up processing in their listening, while they viewed the understanding of each word (bottom-up processing) as essential to listening comprehension. Suggestions and implications are made at the end of the study.

本研究探討高齡者在視覺搜尋作業中，其由上而下（Top-down）與由下而上（Bottom-up）的注意力運作對於情緒刺激的反應，是否會因為注意力功能退化而與年輕成人的表現不同。過去研究指出，雖然高齡者注意力功能衰退，但是高齡者的由上而下注意力運作，仍可以幫助高齡者的表現。為了解由上而下注意力運作是否對於高齡者的反應有所幫助，本研究以兩個實驗分別探討內因與外因線索以及操弄訊息量所造成的影響。 實驗一包括80％有效的內因線索與25％有效的外因線索兩階段，外因線索階段為由下而上注意力運作，內因線索階段則為由上而下注意力運作，獨變項為年齡（高齡者、年輕成人）、情緒（生氣、快樂）以及線索有效情況（有效線索、中性線索、無效線索），記錄反應時間與正確率。實驗二的兩階段使用不同訊息量的外因線索（80％有效比例為高訊息量、25％有效比例為低訊息量），其餘操弄都與實驗一相同，低訊息量為單純的由下而上注意力運作，而高訊息量兼具由下而上與由上而下注意力運作。 研究結果發現，兩實驗高齡者與年輕成人都對於生氣情緒反應較快，符合威脅優勢。高齡者較年輕人更需要借助由上而下的注意力運作幫助反應，高訊息量的線索對於高齡者幫助也較年輕成人大。另外，實驗一增益效果的結果顯示，有效線索在高齡者搜尋生氣臉孔幫助較大，在年輕成人則搜尋快樂臉孔幫助較大，但是實驗二結果則顯示，有效線索在高齡者與年輕成人搜尋快樂臉孔的幫助都較生氣臉孔大，兩實驗的年齡與情緒的交互作用結果不同可能與高齡者異質性有關。由研究結果可知，由上而下注意力運作對於高齡者在情緒臉孔反應有幫助，在未來實務上，可以多運用由上而下注意力運作的線索幫助高齡者反應。 / This research is aim to understand attention in visual search of emotional faces in aging. Two types of attention process, that is top-down and bottom-up attention, were concerned in this study. In past researches, there are empirical evidences showing age-related declination in attention function, especially in bottom-up attention. But top-down attention is still playing an important role in doing task for the older adults. In order to understand the effect of top-down attention in aging, two experiments using endogenous or exogenous spatial cues were designed. Participants have to respond whether there is a different emotional face or not in a visual search task. The independent variables are age（aging and young）, emotional face（happy and angry）, and cue（valid, neutral, and invalid）. Dependent variables are reaction times and accuracy. In Experiment 1, there are two stages: 80％ valid endogenous cues and 25％ valid exogenous cues. The endogenous cues stage and exogenous cues stage were designed to probe top-down attention and bottom-up attention, respectively. In Experiment 2, there are two stages: 80％ valid exogenous cues（highly informative cues）and 25％ valid exogenous cues（non-informative cues）. Using highly informative exogenous cues involve both top-down and bottom-up attention. In contrast, non-informative exogenous cues only trigger bottom-up attention. The major results of this study support threat advantage hypothesis that both older and young adults respond to angry face target quicker than happy face. Benefit from top-down attention was larger in older adults than young adults. Highly informative cues help older adults more in searching emotional faces than young adults. The cuing effects in two emotional face conditions were different between Experiment 1 and 2. This inconsistent result maybe relates to aging heterogeneity. In conclusion, top-down attention can help older adults search for emotional faces.

過去的研究指出，具有威脅訊息的情緒臉孔會比正向情緒臉孔快速地吸引個體的注意力。視覺搜尋研究發現情緒臉孔的突顯程度會引發由下而上的注意力攫取，而由下而上的注意力攫取是否能夠被由上而下的因素所凌駕，一直是一個很重要的論爭，因此，本研究同時呈現兩種情緒臉孔，並以文字線索引發由上而下注意力選擇，以探討由上而下的因素是否能夠凌駕情緒臉孔之注意力攫取，並比較不同情緒臉孔攫取注意力的強度。實驗一探討文字線索是否能夠幫助注意力搜尋目標情緒臉孔。實驗二使用一致效果當作注意力攫取指標，探討當臉孔情緒與作業相關時，由上而下因素是否能夠凌駕干擾情緒臉孔為生氣臉孔或快樂臉孔之注意力攫取，以及比較生氣與快樂臉孔攫取注意力的強度。實驗三延續實驗二的研究，將臉孔情緒改為與作業無關，比較生氣臉孔與快樂臉孔攫取注意力的強度。實驗四與實驗二實驗程序相同，但增加倒立中性臉孔與生氣臉孔或快樂臉孔同時呈現情況，如此在以倒立中性臉孔為目標或干擾臉孔情況，可以比較生氣臉孔與快樂臉孔之由上而下因素注意力選擇與由下而上注意力攫取強度。本研究結果在大部分情況下並未獲得一致效果，顯示由上而下之注意力選擇會影響由下而上之情緒臉孔攫取注意力，使得干擾臉孔未能吸引注意力於其上。然而由下而上注意力攫取仍影響搜尋情緒臉孔的反應時間，結果顯示生氣臉孔與快樂臉孔競爭下，生氣臉孔的突顯程度大於快樂臉孔，說明生氣臉孔較快樂臉孔吸引注意力。 / Previous studies using visual search task showed that the saliency of the emotional faces was sufficient to induce the bottom-up attentional capture. It is a critical debate that whether top-down factors can override bottom-up attentional capture. To address this issue, we presented two emotional faces at the same display while using word cues to induce top-down attentional selection. Experiment 1 investigated the effect of word cues on the target face searching. Using congruency effect as an index of attentional capture, Experiment 2 investigated whether top-down factors could override attentional capture of the emotional distractors when emotion is task-relevant and the degree of attentional capture of angry faces was compared with that of happy faces. In Experiment 3, face emotion was changed to be task-irrelevant rather than task-relevant, and the degree of attentional capture of angry and happy faces was also contrasted. In Experiment 4, the invert neutral face was included additionally as another target or distractor. We can use the invert neutral face as the common basis to dissociate the components of top-down attentional selection and bottom-up attentional capture, and contrast the attention effects between angry and happy faces in these two aspects independently. The results showed that congruency effect could not be found in most conditions. This implies that top-down attentional selection can influence the bottom-up attentional capture of emotional faces. But reaction time for searching target was still found to be influenced by bottom-up process. When an angry face competes with a happy face, the saliency of the angry face is higher than the happy face.
