     It is necessary to retrieve less salient knowledge to think creatively (e.g., idea generation and insight problem solving). We hypothesized that people retrieve less salient knowledge by searching for a commonality between unrelated objects rather than by thinking about an object itself. In Experiment 1, fifty undergraduates were assigned to one of two groups:commonality search and word association. While the participants in the commonality search group were asked to list the commonalities between unrelated objects (e.g., a strawberry and a television), those in the word association group were asked to list as many words as they could remember from each object. The answers listed by the participants in the commonality search group were less salient than those in the word association group. In Experiment 2, we obtained the same pattern of results as those of Experiment 1 with modified procedure and measures of saliency. We concluded that the commonality search between unrelated objects is effective in retrieving less salient knowledge.

     In order to generate novel ideas, it is necessary to find obscure features in objects. We propose commonality search as a way to find obscure features between apparently unrelated objects. We carried out two experiments to examine the effectiveness of this method. In Experiment 1, we investigated the effects of commonality search on evoking original perspectives. Twenty undergraduates were asked to rate the degree of relatedness within 18 pairs of objects: 9 related (e.g., a strawberry and a melon) and 9 unrelated pairs (e.g., a banana and a motor bike). They were then asked to list commonalities between the paired objects. Three independent raters scored commonalities in terms of validity, originality, and attractiveness. The results revealed that the unrelated pairs evoked commonalities with higher originality and attractiveness scores. In Experiment 2, we investigated how commonalities were discovered using a protocol analysis. Twenty-one participants were asked to think aloud while listing commonalities. Two independent raters scored commonalities in the same way as Experiment 1. The effects of relatedness between objects on perspectives was replicated. The results also showed that the participants discovered more original commonalities through the adaptation strategy. We conclude that commonality search between unrelated objects evokes original perspectives and the adaptation strategy is effective in evoking more original perspectives.

    <p>This study investigates the influence of writers' executive function capacities on the processes of translating their ideas as part of creating written compositions. In contrast to previous studies, where participants composed used ballpoint pens in order to limit rewriting, the participants within the present study composed used mechanical pencils and erasers to encourage rewriting. Participants with high scores on a reading-span test produced fewer sentences through associative and automatic processes than those with lower scores. This finding indicates that writers with superior executive functions are more capable of translating their ideas into text and refrain from producing excessive sentences.</p>

  5. Expression Process of Mental Representation in Writing::Automaticity and Controllability in Expressing Representation Reviewed

    This research proposed a new model of representational change in writing. In this<br> model, two processes — the construction phase and the expression phase — are al<br> ternatively repeated. In the construction phase, a mental representation of writing<br> tasks changes from a propositional representation of sentence-by-sentence in text to a<br> representation such as a summary of text, and finally changes into an abstract repre-<br>sentation reflecting deeper understanding. The expression phase is the reverse of the<br> construction phase; representation changes from abstract to propositional. Addition-<br>ally, this research assumed that the expression phase consisted of an automatic process<br> and a controlled process. The automatic process involves writing the main message,<br>and the controlled process involves writing another sentence that adds information to<br> the previously written sentence or gives concrete examples. After two experiments were<br> conducted to confirm the hypothesis, the results revealed that a portion of the main<br> written message was not related to the amount of resources necessary for the function-<br>ing of the control system; moreover, the amount of resources required for the proper<br> functioning of the control system facilitated a portion of the added sentences. These<br> two results are significant in proposing a new model and understanding the writing<br> process, and show that the mental process of writing includes an automatic process<br> and a controlled process.

    本年度は共通点の探索が固定的な見方の解消に有効であることを検討する2つの研究を行った。
    研究1では,関連性の低い2つの対象間における共通点の探索によって対象の固定的な見方の解消が促進されるかを検討した。対象の特徴を探索する課題を用いて,思いつきにくい特徴を挙げられることをもって固定的な見方が解消されるとみなした。2つの対象間に共通する特徴を探索する条件(以下,共通点探索条件)と,1つの対象の特徴を挙げる条件(単一特徴条件)を設けて,記述される特徴(以下,特徴語)と挙げた特徴をもつ別の事物(以下,連想語)を列挙する課題を行い,記述される内容の思いつきやすさの比較を行った。特徴語は単一特徴条件に比べて共通点探索条件の思いつきやすさが低く,共通点の探索によって思いつきにくい特徴への着目がなされることが示された。
    研究2では,共通点を探索による固定的な見方の解消を別のアプローチから検討した。具体的には,固定的な見方の解消,すなわち,物事の目立たない特徴への着目が促進されるのであれば,共通するプロセスを有する別の課題との間に相関関係が見られると予想した。共通点探索課題と類似したプロセスを有すると考えられる課題として,カテゴリ列挙課題との関連を検討した。実験参加者による共通点探索課題およびカテゴリ列挙課題の回答数の相関係数を算出したところ,有意な正の相関が見られた。この結果は,共通点発見課題において共通点を多く列挙できる人ほど,カテゴリ列挙課題においてもカテゴリを多く列挙できることを示している。このことから,共通点探索課題とカテゴリ列挙課題は,目立たない特徴への着目を共通するプロセスとして有していることが示唆された。
    これら2つの研究から,共通点の探索が固定的な見方の解消につながることを示唆する知見が得られた。
