・恋は、かけ引き。
―戦略的に、男心をくすぐってください
―デートをいつにするか: 重要な課題
あのさ、
今日これから
デートしない?
あのさ、
来週の日曜
デートしない?
1. 研究の背景
「いつキスをするのが最も魅力的か?」
今日のキスより3日後!最も魅力的!
― キスの魅力+待つわくわく(savouring)の加算
Anticipation and the Valuation of Delayed Consumption

2. 研究の目的
“いつのデート”にお誘いすれば
女性は男心を くすぐれるのか?
時間で変化するデートの魅力を、
遅延価値関数 & 階層ベイズで推定(R & rstan)

デートは、
あえて来週。
わくわくさせるんだから
3. 研究の方法
・デート予定の選択実験(男性参加者14名)
― モデル女性: 4名(大学院生による任意選抜)
― デートまでの日数: 1,3,5,7,30 日
― 全通り組み合わせ・ランダム順序提示
80選択
「今日デートする?」 vs 「 t日後デートする?」
3. 研究の方法
・モデルさんに対する「好み得点」の利用
―「好み」の影響を考慮する工夫
数百行の小規模データ確認に便利
{formattable}
formattable(Dat)
4. 研究の結果①
①「今日」 vs 「後日」だったら、男はどっちがい
い?ggplot(df.plot,aes(x=DelayTime,y=probChooseLater))+
geom_hline(yintercept = 0.5,linetype=2)+
geom_point(colour="darkblue",size=2)+
geom_line(colour="darkblue",size=1.1)
{ggThemeAssist}が便利
修正・変更がラクラク
4. 研究の結果①
「男は3日後以降のデートを選ばない!」
①「今日」 vs 「後日」だったら、男はどっちがい
い?
後日がいい!ゾーン
今日がいい!ゾーン
4. 研究の結果②
②時間で変化するデートの魅力

参加者𝑖 さんにとって、モデル𝑗 さんと、
今日デートする価値(𝑉𝑖𝑗

)は、
モデル女性への好み得点 (𝐴𝑖𝑗)で定義
参加者𝑖さんがモデル𝑗さんと
𝑡日後にデートする価値(𝑉𝑖𝑗𝑘

)は、
モデル女性への好み得点 (𝐴𝑖𝑗)と
𝑡日を待つわくわく(𝛾𝑖
𝑡 𝑘

の和で定義
<ソフトマックス行動選択>

exp(𝛽𝑖 ∙ 𝑽𝑖𝑗

4. 研究の結果②
「男は明日のデートに最もわくわくする」

魅力下がる…ゾーン
4. 結論
・男は「3日後以降のデートを選ばない傾向」
・男は明日のデートに一番わくわくする
・女性の皆さんは戦略的に、
男性を明日のデートに誘いましょ。
あした、あいてます。
