combining computer game-based behavioural experiments with high-density eeg and infrared gaze tracking

それらの刺激のタイミングやその他のパラメータをよく指定して制御されている限り、実験的なパラダイムは貴重であり、彼らは生態学的に有効な条件下で発生した認知処理に関連するデータが得られる限り。よく制御された刺激は、しばしば、被験者のモチベーションを維持するためにあまりにも繰り返されるので、これら2つの目標は、しばしば、対立している。脳波を脳波（EEG）を用いた研究は、しばしば生態学的妥当性および実験制御の間にこのジレンマに非常に敏感です：生理平均で達成するに十分な信号対雑音は、能力と個人にテーマプールを制限し、長時間録音の中で繰り返された試行の多数の要求と何度も何度設定タス​​クを実行するための忍耐。この制約は、深刻な若年層の人口と同様に高まり、不安や注意の異常と関連臨床集団を調査する研究者の能力を制限する。であっても成人、非臨床試験の被験者は、パフォーマンスや認知関与の彼らの典型的なレベルを達成できない可能性があります：実験的なタスクは同じ、、行動、認知、または神経調節雑用より少しされていないですやる気が主題誰のために、として本質的にやる気とタスクに従事している対象。文学の成長体は、ビデオゲーム内で実験を埋め込むことが実験的制御と生態学的妥当性の間にこのジレンマの角の間に方法を提供することができることを示しています。ゲームの物語は、彼らの生態学的妥当性（チェイター＆シュミッター-エッジコム、2003）の強化、タスクが発生するより現実的なコンテキストを提供します。また、このコンテキストはタスクを完了するためにモチベーションを提供します。私たちのゲームでは、被験者は、海賊を撃退、資源を収集するための通信を傍受するに様々なミッションを実行するか、外交関係を促進する。そうすることで、彼らはまた、ポズナー注意シフトパラダイム（ポズナー、1980）、運動抑制、心理物理学的運動のコヒーレンスのしきい​​値タスクを、組込み図テスト（ウィトキンのGO / NO -に行くテストを含む、認知タスクの配列を、実行、1950、1954）と理論の心（ウィマー＆Perner、1983）タスク。ゲームソフトは、ログファイルに自動的にゲームの刺激と被験者の行動や反応を登録し、生理学的データレコーダーと同期するイベントコードを送信します。このようにゲームは、EEGやfMRIを、そして視線の瞬間から瞬間の追跡と同様に生理的な措置と組み合わせることができます。瞳孔拡張（ブラッドリーら 、2008）に反映されている視線の追跡は、行動的なタスク（例えば、固定）と実験的刺激に対する明白な注意を払って、被験者の遵守を確認し、また生理的覚醒ができます。新しいオブジェクトを小さな穴のあるするには小さすぎるが、発症のような急速な眼球運動をし、同じように角距離とピーク速度との間の同じ関係を持って - 偉大な十分なサンプリング周波数では、視線の追跡もmicrosaccadesに反映されている秘密の注目を評価に役立つことがあります長い距離を通過するサッケード。 microsaccadesの方向の分布は、注目の（特に）秘密の方向（Hafed＆クラーク、2002）と相関している。
