Abstract We investigated the relationship between, and functional significance of, P 300, novelty 3, pupil dilation response ( PDR ). Subjects categorized stimuli including (a) words of a frequent category, (b) an infrequent category (14%), (c) pictures (“novels”; 14%). The 300 3 were uncorrelated with differed in their to experimental manipulation. Therefore, although three physiological responses often co‐occur, they appear each manifest distinct function: may be more closely linked...
The error-related negativity (ERN) is thought to index an anterior cingulate (ACC) behavioral monitoring system. feedback ERN (FRN) elicited error when the correct response not known, but also a choice outcome suboptimal and passive reward prediction violation, suggesting that system may be restricted actions. This study used principal components analysis show consists of single central component whereas violation FRN comprised prefrontal components. A present in action occurs later, at...
We investigated the contribution of familiarity and recollection to associative retrieval word pairs depending on extent which have been unitized through task instructions in encoding phase. Participants unitization condition encoded context a definition that tied them together such they were treated as coherent new item, while control inserted into sentence frame each remained an individual unit. Contrasting event-related potentials (ERERPs) elicited subsequent recognition test by old...
The "subsequent memory paradigm" is an analysis tool to identify brain activity elicited during episodic encoding that associated with successful subsequent retrieval. Two commonly observed ERP effects" (SMEs) are the parietal SME in P300 time window and frontal slow wave SME, but date a clear characterization of circumstances under which each missing. To test hypothesis occurs when aspects experience unitized into single item representation, while inter-item associative reflected effect,...
Objectives Diabetes distress can negatively affect the well-being of individuals with type 1 diabetes (T1D). Voice-based (VB) technology be used to develop inexpensive and ecological tools for managing distress. This study explored competencies engage digital health services, needs preferences T1D or caring a child this condition regarding VB inform tailoring co-designed tool supporting management. Design We mixed methods design. performed qualitative reflexive thematic analysis...
The N2pc is widely employed as an electrophysiological marker of attention allocation. This interpretation was largely driven by the observation elicited isolated relevant target object, which reported Experiment 2 in Eimer (1996). All subsequent refined interpretations had to take this crucial finding into account. Despite its central role for neurocognitive research, there have been no direct replications and only few conceptual seminal work. Within context #EEGManyLabs, international...

Abstract We examined the factors that contribute to enhanced recall for emotionally arousing words by analyzing behavioral performance, P300 as an index of distinctiveness, and N400 semantic expectancy violation in a modified Von Restorff paradigm. While their EEG was recorded, participants studied three list types (1) neutral including one isolate (either positive or negative), (2) arousing, negative isolate, (3) isolate. Immediately after each list, free tested. Negative, but not positive,...
Abstract Belief in life after death offers potential comfort the face of inevitable death. However, afterlife belief likely requires not only an awareness but also body–self dualism—the perception that self (e.g., mind) is distinct from physical, undeniably mortal, body. In turn, we hypothesized mortality salience (MS) should heighten when dualism facilitated. Study 1 found MS increased for people high, relative to low, trait mind–body dualism. 2, first wrote about their thoughts and...
We examined the degree to which ERP components elicited by items that are isolated from their context, either font size ("size isolates") or frequency of usage, correlated with subsequent immediate recall. Study lists contained (a) 15 words including a isolate, (b) 14 high (HF) one low word ("LF isolate"), (c) LF HF word. used spatiotemporal PCA quantify components. replicated previously reported P300 memory effects for isolates and found additional correlations recall in novelty P3, right...
Abstract The present study examined the mechanisms underlying stimulus sequence effects on parietal P300 and frontal P3a elicited by infrequent targets in an oddball paradigm compared these between young older adults. Fifty 50 healthy adults completed a simple visual task including (20%) target stimulus. A temporo‐spatial principal component (PCA) analysis was used to disentangle from overlapping ERP components. typical age‐related anterior‐shift of was, according PCA, due disproportionately...
We investigated whether healthy older adults are able to use an episodic encoding strategy known as unitization, which allows for subsequent associative retrieval based on familiarity, overcome their memory deficit. Young and participants were presented with word pairs either together a definition that allowed combine the new concept (high unitization condition), or sentence frame (low condition). In Experiment 1, age-related reduction in performance standard recognition test was observed...
Abstract After imagining being stranded in the grasslands of a foreign land without any basic survival material and rating objects with respect to their relevance this situation, participants show superior memory performance for these compared control scenario. A possible mechanism responsible advantage is richness distinctiveness which information encoded survival-scenario condition. When confronted unusual task thinking about how an object can be used life-threatening context, will most...
Humans preferentially remember information processed for their survival relevance, a memorial benefit known as the processing effect . Memory is also biased towards associated with prospect of reward. Given adaptiveness these effects, they may depend on similar mechanisms. We tested whether motivation drives both reward incentives that are to boost extrinsic and perhaps stimulating intrinsic motivation. Accordingly, we manipulated incentive independently during an incidental-encoding task in...
Abstract Memories formed in the context of an imagined survival scenario are more easily remembered, but mechanisms underlying this effect still under debate. We investigated neurocognitive processes processing by examining event-related potentials (ERPs) during memory encoding. Participants being either stranded a foreign land and needing to survive, or overseas moving (control) scenario, while incidentally encoding list words. Words encountered were associated with improved recall reduced...
