Does semantic congruence between information presented in distinct modalities increase episodic memory for that event, compared to semantic incongruence?
No full textThe goal of this study is therefore to test whether images that are encoded with semantically congruent sounds are better remembered at long-term than images presented with semantically incongruent sounds. Here our main question is: does semantic congruence between information presented in distinct modalities increase episodic memory for that event, compared to semantic incongruence?
Our hypothesis is that semantically congruent information increases the elaboration or 'spread' of the encoding (i.e., total breadth of analysis carried out), compared to semantically incongruent information, as discussed in Craik and Tulving (1975) offering a cognitive explanation for the levels of processing effect and the related congruency effect. According to this proposal, recollection is enhanced to the extent that the (crossmodal) information forms an integrated semantically meaningful unit. Therefore, one would expect that semantically congruent multimodal stimuli will be better recollected than incongruent ones because a more elaborate trace is encoded, and because in such cases the structure of semantic memory can be utilized more effectively.
To test this, we measured episodic memory for visual objects presented simultaneously with semantically congruent sounds, compared with visual objects presented with semantically incongruent sounds. We use the most widely accepted definition of episodic memory as long-term memory supported by recollection of past events. That is, in accord with the widely accepted dual process view, although recognition may be supported by both recollection and familiarity, conscious recollection is the critical process supporting episodic memory (see for reviews Tulving, 2002; Yonelinas, 2001). More specifically, we implemented the dual-process signal-detection model (Koen et al., 2017) to measure recollection and make the critical test comparing the congruent and the incongruent condition.
To avoid possible confounds due to variations in encoding strategies, we designed an incidental encoding paradigm in which participants were instructed to rate the congruence of the audio and visual components of a list of audio-visual stimuli. The recognition test to measure long-term memory took place 2 days later. Furthermore, to assess whether the effects could be associated to recollection retrieval processes, a ROC curve analysis was implemented (Juola et al., 2019; Yonelinas, 2002), which allows calculating the Recollection parameter (R), as defined by the dual-process signal detection model (DPSD, (Yonelinas, 2002; Yonelinas et al., 2010))

Energy Dynamics Awareness - Main Validation
No full textIn this study, we further examine an energy specific situation awareness concept called Energy Dynamics Awareness (EDA). EDA helps to perceive, integrate and reason energy dynamics correctly in order to enable energy efficient decisions or behavior. One way to enhance EDA is to provide energy feedback interfaces designed to enhance situation awareness according to Endsley (2003). Participants watch two driving scenes (with different energy consumption) on video along with additional driving data information for three different routes (= six scenes in total). For each route the energy feeback design is differently supporting EDA. After each scene, participants have to guess the energy consumption and after both scenes decide which scene was more energy efficient. We link newly designed EDA measures with energy decisions to validate the use of EDA in the field of energy-efficient behavior. This study is the second and enhanced study after the first pilot here: https://osf.io/ts7vm/
