Abstract: Working memory (WM) plays a crucial role in various cognitive tasks from language comprehension to problem-solving. However, its influence on social activities has remained largely unexplored. The current two studies on individual differences, a pilot (N = 329) and a pre-registered direct replication (N = 338) study, investigated the relationship between WM and outside-the-lab social interaction by using a listening span task and three social network questionnaires (e.g., how many people a participant had contacted in the past month). The consistent patterns in the two studies were (a) WM recall was positively correlated with social network size, (b) WM recall remained positively correlated with social network size even when accounting for online interactions on WhatsApp and Facebook, and (c) WM recall was positively correlated with social network size by face-to-face interaction. These novel findings would suggest connections between WM and face-to-face social interaction. It was, however, acknowledged that the obtained effect sizes were small, and that further investigation is indeed necessary. In light of this, we also clarify future directions for understanding the relationship between WM and social interaction.

日本語によるコメント：
ワーキングメモリが認知成績と正の相関を持つことは繰り返し報告されています。一方で、ワーキングメモリが社会的活動と関連するかについては未解明な部分が多く残っております。私たちの研究では、ワーキングメモリ成績の個人差が「過去一ヶ月間で会った人物の数」と正の相関を持つことを確認しました。さらに、効果量は小さいですが、事前登録された直接的追試実験によって、この相関は追試されました。なお、本論文は日本認知心理学会第21回大会（東京都立大学）での口頭発表の内容に基づいております。この場を借りてご報告できることを嬉しく思います。（石黒）
