Emotional valence boosts partial and specific source memory
Previous research has shown that source memory is enhanced for emotionally valenced sources. However, it remains unclear whether this enhancement relies on better memory for specific source details or merely improved memory for the source-valence category. The present study addresses this question and disentangles emotion-based effects on partial and specific source memory using multinomial modeling. Participants ( N =67) encoded neutral words pa…
Emotion-enhanced source memory
This preregistered research examined whether younger and older adults robustly show enhanced source memory for socio-emotional versus neutral sources in a lab- and online-based experimental setting. The Lab Experiment (N = 138) was conducted in a lab room with German-speaking younger and older adults, while the Online Experiment (N = 136) was run on Prolific with English-speaking younger and older samples. In both experiments, neutral faces (= it…
Enhanced source memory for emotionally valenced sources
Previous research on whether source memory is enhanced for emotionally valenced sources yielded inconclusive results. To identify potential boundary conditions, we tested whether encoding instructions that promote affective versus different types of non-affective item-source-processing foster versus hamper source-valence effects. In both experiments, we used neutral words as items superimposed on emotional (positive & negative) or neutral picture…
In Colore Veritas? Color effects on the speed and accuracy of true/false responses
In addition to their perceptual or aesthetic function, colors often carry conceptual meaning. In quizzes, for instance, true and false answers are typically marked in green and red. In three experiments, we used a Stroop task to investigate automatic green-true associations and red-false associations, respectively. In Experiments 1 and 2, stimuli were true statements (e.g., “tables are furniture”) and false statements (e.g., “bananas are building…
Better memory for emotional sources? A systematic evaluation of source valence and arousal in source memory
Emotion-enhanced memory (EEM) describes the robust memory advantage of emotional over non-emotional stimuli. While extensively investigated with emotional items, it is unclear whether the EEM effect extends to source memory for a neutral item's emotional context. In two pre-registered studies, we systematically manipulated source valence (positive, negative) between participants and source arousal (high, low, neutral-low) within participants. In …
A novel paradigm to assess storage of sources in memory
The present research aimed to devise a test of source recognition that facilitates access to source information stored in memory. Therefore, we extended the standard source-monitoring paradigm, in which items are presented in a source-neutral manner during test, by a second, subsequent test with source reinstatement. In this second test, items (i.e., words) were presented with both study sources (i.e., two speakers) consecutively such that for or…
