The uncanny valley (UV) effect is a negative affective reaction to human-looking artificial entities. It hinders comfortable, trust-based interactions with android robots and virtual characters. Despite extensive research, a consensus has not formed on its theoretical basis or methodologies. We conducted a meta-analysis to assess operationalization...

The human brain encodes information in neural activation patterns. While standard approaches to analyzing neural data focus on brain (de-)activation (e.g., regarding the location, timing, or magnitude of neural responses), multivariate neural pattern similarity analyses target the informational content represented by neural activity. In adults, a n...

The specificity with which past experiences can be remembered varies across the lifespan, possibly due to differences in how precisely information is encoded. Memory formation can be investigated through repetition effects, the common finding that neural activity is altered when stimuli are repeated. However, whether differences in this indirect me...

... Research that used morphed images found support for the uncanny valley hypothesis (e.g., Lischetzke et al., 2017;MacDorman & Ishiguro, 2006;Mathur & Reichling, 2009 but this line of research was criticized for the lack of external validity (Diel et al., 2022;Palomäki et al., 2018). A recent review and meta-analysis (Mara et al., 2022) demonstrated that higher scores on human likeness were absent in experiments that used realistic human-like robots. ...
... The sample dataset includes EEG data from ten 7-9-year-old children (6 female, 4 male) and ten 18-30-year-old adults (5 female, 5 male) during the encoding phase of an episodic memory study ( Fig. 1; for a detailed description of the task and data preprocessing, see Sommer et al., 2021). The data made available stem from a subsample of the original participants and selected conditions of the original experiment that allow the interested reader to run this tutorial. ...
... These results suggest that older adults, in particular those with low IFG integrity and reduced SMEs in the alpha/beta band, tend to form memory representations that have undergone less deep elaboration during encoding and may as a consequence contain fewer details. In other words, while the general mechanisms that underlie successful memory formation appear not to change across adulthood, the probability to successfully engage memory formation operations does seem to deteriorate as well as the level of detailedness or specificity of memories (see also Sommer et al., 2020). ...
