q3 i? In homogeneous HT-HT and LT-LT sequences, ES trustworthiness evaluations did not change between the first and second document positions. → Franco Londra 2025

Franco Londra, Magalí Martínez, Gaston Saux. (2025). Sources within sources: The dynamic influence of multiple documents trustworthiness when evaluating and using an embedded source. Metacognition and Learning. https://doi.org/10.1007/s11409-025-09427-z

q3 · i? · causal · r2

Linear mixed-model analysis of ES trustworthiness ratings (0–10) from 72 undergraduates reading two texts in homogeneous sequences. The article reports no position effect: "ES evaluations did not change between Position within the sequence in the HT-HT and LT-LT sequences" with the printed t and p values.

"Finally, ES evaluations did not change between Position within the sequence in the HT-HT and LT-LT sequences, t(66) = −0.82, p =.415 and t(66) = 1.38, p =.171"

Discussion¶

Related Claims¶

• References to document sources showed a significant sequence-type by position interaction, driven by first-position texts in the HT-LT sequence; the hypothesized increase in mixed sequences was only partly supported
• References to the embedded source did not differ by sequence type, ranging from 17.6% to 35% across conditions
• Embedded-source and document-source trustworthiness scores differed, suggesting an interplay between layers rather than one-layered reflection — related
• Embedded-source trustworthiness evaluations shift toward the trustworthiness of the most recent document source in mixed sequences — related
• After reading the first text, embedded-source trustworthiness evaluations did not vary between sequences — related
