“…They showed an increased posterior negativity around 200 ms (N200) for ongoing task events performed concurrently with a PM task, relative to ‘ongoing-only task’ performance. This evidence has been corroborated by other researchers (Czernochowski et al, 2012; Knight et al, 2010). Thus, the first question we address in this study is: can the N200 also be found when monitoring conceptual PM cues or is it specific to the monitoring of perceptual PM cues?…”

“…These findings have been replicated for perceptual PM paradigms only (Cousens et al, 2015; Knight et al, 2010; West, 2011). In the comparison of perceptual versus conceptual PM tasks, Cousens et al (2015) observed that only the perceptual task condition elicited the N300, concluding that this modulation may correspond to a specific rather than a general marker of perceptual cue detection.…”

“…Traditional experimental designs in PM evaluate monitoring by comparing performance of an ongoing task performed in conjunction with a PM task (ongoing+PM task condition) with the performance of the same task without the PM task embedded (ongoing-only task condition) (Czernochowski et al, 2012; Guynn, 2003, 2008; Marsh et al, 2003; Smith, 2003, 2010; Smith et al, 2007). The same approach has been used to explore the neural correlates of monitoring in PM (Cona et al, 2012; Czernochowski et al, 2012; Knight et al, 2010; West et al, 2006; West et al, 2007). West et al (2006, 2007) showed the first evidence of a monitoring effect (called the prospective interference effect in their studies) using perceptually salient PM cues.…”

ERPs and their brain sources in perceptual and conceptual prospective memory tasks: Commonalities and differences between the two tasks

The present study examined whether Event-Related Potential (ERP) components and their neural generators are common to perceptual and conceptual prospective memory (PM) tasks or specific to the form of PM cue involved. We used Independent Component Analysis (ICA) to study the contributions of brain source activities to scalp ERPs across the different phases of two event-based PM-tasks: (1) holding intentions during a delay (monitoring) (2) detecting the correct context to perform the delayed intention (cue detection) and (3) carrying out the action (realisation of delayed intentions). Results showed that monitoring for both perceptual and conceptual PM-tasks was characterised by an enhanced early occipital negativity (N200). In addition the conceptual PM-task showed a long-lasting effect of monitoring significant around 700 ms. Perceptual PM-task cues elicited an N300 enhancement associated with cue detection, whereas a midline N400-like response was evoked by conceptual PM-task cues. The Prospective Positivity associated with realisation of delayed intentions was observed in both conceptual and perceptual tasks. A common frontal-midline brain source contributed to the Prospective Positivity in both tasks and a strong contribution from parieto-frontal brain sources was observed only for the perceptually cued PM-task. These findings support the idea that: (1) The enhanced N200 can be understood as a neural correlate of a ‘retrieval mode’ for perceptual and conceptual PM-tasks, and additional strategic monitoring is implemented according the nature of the PM task; (2) ERPs associated with cue detection are specific to the nature of the PM cues; (3) Prospective Positivity reflects a general PM process, but the specific brain sources contributing to it depend upon the nature of the PM task.

“…Interestingly, Cohen et al (2008) analysed word and nonword lexical decision task trials separately and showed more task interference on ongoing LDT word trials relative to nonword trials when participants had a word PM target. Many studies of prospective memory use lexical decision making as the ongoing task and words as PM targets however most of these studies analyse ongoing task performance solely in terms of performance on word LDT trials (for exceptions see Knight, Ethridge, Marsh, & Clementz, 2010;Scullin, McDaniel, Shelton, & Lee, 2010).…”

A current issue in the field of prospective memory (i.e., memory for intentions) is the extent to which intentions interfere with ongoing activities. A question of interest is whether this interference is specific to stimuli that are relevant to the intention or whether interference is more general in its influence. Participants performed a lexical decision task (LDT) with an embedded prospective memory (PM) task in which they had to remember to press a computer key if a pre-specified target appeared (e.g., GIRL). Results demonstrated a consistent pattern of results. Increased reaction time costs were observed on trials where there was a match between PM targets and non-target ongoing stimuli. That is, when a prospective memory target was a word, then reaction time costs were observed on non-target word LDT trials and there were no costs on non-target nonword trials. Similarly, if a PM target was a nonword (e.g., UEBL) then costs were observed on non-target nonword LDT trials relative to non-target word trials. Evidence from three experiments suggests that task interference is specific to the type of stimulus (word or nonword) that is relevant to the intention. We refer to this finding as a Stimulus Specific Interference Effect (SSIE).

Episodic-autobiographical memory (EAM) is considered to emerge gradually in concert with the development of other cognitive abilities (such as executive functions, personal semantic knowledge, emotional knowledge, theory of mind (ToM) functions, language, and working memory). On the brain level its emergence is accompanied by structural and functional reorganization of different components of the so-called EAM network. This network includes the hippocampal formation, which is viewed as being vital for the acquisition of memories of personal events for long-term storage. Developmental studies have emphasized socio-cultural-linguistic mechanisms that may be unique to the development of EAM. Furthermore it was hypothesized that one of the main functions of EAM is the social one. In the research field, the link between EAM and social cognition remains however debated. Herein we aim to bring new insights into the relation between EAM and social information processing (including social cognition) by describing a young adult patient with amnesia with neurodevelopmental mechanisms due to perinatal complications accompanied by hypoxia. The patient was investigated medically, psychiatrically, and with neuropsychological and neuroimaging methods. Structural high resolution magnetic resonance imaging revealed significant bilateral hippocampal atrophy as well as indices for degeneration in the amygdalae, basal ganglia, and thalamus, when a less conservative threshold was applied. In addition to extensive memory investigations and testing other (non-social) cognitive functions, we employed a broad range of tests that assessed social information processing (social perception, social cognition, social regulation). Our results point to both preserved (empathy, core ToM functions, visual affect selection, and discrimination, affective prosody discrimination) and impaired domains of social information processing (incongruent affective prosody processing, complex social judgments). They support proposals for a role of the hippocampal formation in processing more complex social information that likely requires multimodal relational handling.
