Para cualquier persona que trabaje en seguridad, o simplemente en situaciones de presión, esto muestra que el cuerpo influye en el juicio más de lo que creemos. Es un experimento chico, con 31 personas, así que sus conclusiones deben tomarse como una pista y no como una regla general.","quienFirma":"bioRxiv (preprint, institución de los autores no especificada en el resumen)","confianza":"preprint","consulta":{"pregunta":"¿Crees que el miedo puede hacerte juzgar mal una situación?"}},"sello":{"hash":"e75545e1c80130f43490ef2dab80d7aaf7535878ac2817473dba3423e5effcc1","sello":"23acb4207e3168796e3152720f5a7bbe147649b1d7420160a703960cefce12d1","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6576903,"aleatorio":"8e583525a288ba13cde66d0d6539d282d867cec58f75a0217a855687a27f9649","tiempo":"2026-10-23T06:48:30.000Z"},"nist":{"cadena":2,"pulso":1995651,"salida":"AA82134D649B7B25F10D77FD67053808011261EF94B49E048C931DF7D357E824C95C66604E50CE6E37F934A39EE493177DEA66983586EA3E4667145C3C8919D6","tiempo":"2026-10-23T06:48:00.000Z"},"noAntes":"2026-10-23T06:48:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 23 06:48:58 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Stress, Heartbeats, and Biases: Cardiac phase and acute stress modulate affective and spatial response bias.","descripcion":"Threatening situations often require rapid decisions which are particularly susceptible to response bias. The perception of threat also elicits an acute stress reaction, assumed to promote automatic action tendencies via several mechanisms. Cardioafferent signals during systole, for example, increase racially biased misidentifications of tools as weapons. Acute stress, linked to threat-biased decisions may both bias such decisions directly and alter cardiac effects on them. Here, we investigated the effects of cardiac phase and acute stress in a combined Weapon Identification and Simon Task. Thirty-one participants classified laterally or vertically presented weapons and tools with lateraliz","pubDate":"2026-10-22","url":"https://www.biorxiv.org/content/10.64898/2026.10.18.759627v1?rss=1"},"indexado":"2026-10-23T06:48:38.804Z"}}
