Spatial Predictive Context Speeds Up Visual Search by Biasing Local Attentional Competition.

The human visual system is equipped to rapidly and implicitly learn and exploit the statistical regularities in our environment. Within visual search, contextual cueing demonstrates how implicit knowledge of scenes can improve search performance. This is commonly interpreted as spatial context in the scenes becoming predictive of the target location, which leads to a more efficient guidance of attention during search. However, what drives this enhanced guidance is unknown. First, it is under debate whether the entire scene (global context) or more local context drives this phenomenon. Second, it is unclear how exactly improved attentional guidance is enabled by target enhancement and distractor suppression. In the present magnetoencephalography experiment, we leveraged rapid invisible frequency tagging to answer these two outstanding questions. We found that the improved performance when searching implicitly familiar scenes was accompanied by a stronger neural representation of the target stimulus, at the cost specifically of those distractors directly surrounding the target. Crucially, this biasing of local attentional competition was behaviorally relevant when searching familiar scenes. Taken together, we conclude that implicitly learned spatial predictive context improves how we search our environment by sharpening the attentional field.

Sex-Specific Effects of Early Life Unpredictability on Hippocampal and Amygdala Responses to Novelty in Adolescents.

Unpredictable childhood experiences are an understudied form of early life adversity that impacts neurodevelopment in a sex-specific manner. The neurobiological processes by which exposure to early-life unpredictability impacts development and vulnerability to psychopathology remain poorly understood. The present study investigates the sex-specific consequences of early-life unpredictability on the limbic network, focusing on the hippocampus and the amygdala. Participants included 150 youth (54% female). Early life unpredictability was assessed using the Questionnaire of Unpredictability in Childhood (QUIC). Participants engaged in a task-fMRI scan between the ages of 8 and 17 (223 total observations) measuring BOLD responses to novel and familiar scenes. Exposure to early-life unpredictability associated with BOLD contrast (novel vs. familiar) in a sex-specific manner. For males, but not females, higher QUIC scores were associated with lower BOLD activation in response to novel vs. familiar stimuli in the hippocampal head and amygdala. Secondary psychophysiological interaction (PPI) analyses revealed complementary sex-specific associations between QUIC and condition-specific functional connectivity between the right and left amygdala, as well as between the right amygdala and hippocampus bilaterally. Exposure to unpredictability in early life has persistent implications for the functional operations of limbic circuits. Importantly, consistent with emerging experimental animal and human studies, the consequences of early life unpredictability differ for males and females. Further, impacts of early-life unpredictability were independent of other risk factors including lower household income and negative life events, indicating distinct consequences of early-life unpredictability over and above more commonly studied types of early life adversity.

Biologically inspired architecture for the identification of ambiguous objects using scene associations

As humans, we have an excellent performance when perceiving the environment. In the artificial world, it is important for machines to perceive their environment so they can make correct decisions and act accordingly. An essential process to accomplish perception is to identify objects in a scene, but, as in reality, these objects can appear as ambiguous, and additionally, those objects are embedded into a particular scene. For our proposal, we created an architecture to identify ambiguous objects by using scene information to guide the identification process. The design is based on the human cortical systems that participate in object and scene recognition. In our study, we validate this proposal by analyzing a prior human experiment that demonstrates and quantifies the impact of scene information on ambiguous objects. Our findings demonstrate that employing the presented architecture on an object recognition task results in superior machine performance with familiar scenes, as opposed to unfamiliar or absent ones, consistent with human behavior.

Familiarity Alters the Bandwidth of Perceptual Awareness.

Results from paradigms like change blindness and inattentional blindness indicate that observers are unaware of numerous aspects of the visual world. However, intuition suggests that perceptual experience is richer than these results indicate. Why does it feel like we see so much when the data suggests we see so little? One possibility stems from the fact that experimental studies always present observers with stimuli that they have never seen before. Meanwhile, when forming intuitions about perceptual experience, observers reflect on their experiences with scenes with which they are highly familiar (e.g., their office). Does prior experience with a scene change the bandwidth of perceptual awareness? Here, we asked if observers were better at noticing alterations to the periphery in familiar scenes compared with unfamiliar scenes. Here, we found that observers noticed changes to the periphery more frequently with familiar stimuli. Signal detection theoretic analyses revealed that when observers are unfamiliar with a stimulus, they are less sensitive at noticing (d') and are more conservative in their response criterion (c). Taken together, these results suggest that prior knowledge expands the bandwidth of perceptual awareness. It should be stressed that these results challenge the widely held idea that prior knowledge fills in perception. Overall, these findings highlight how prior knowledge plays an important role in determining the limits of perceptual experience and is an important factor to consider when attempting to reconcile the tension between empirical observation and personal introspection.

Visual Recognition Memory of Scenes Is Driven by Categorical, Not Sensory, Visual Representations.

When we perceive a scene, our brain processes various types of visual information simultaneously, ranging from sensory features, such as line orientations and colors, to categorical features, such as objects and their arrangements. Whereas the role of sensory and categorical visual representations in predicting subsequent memory has been studied using isolated objects, their impact on memory for complex scenes remains largely unknown. To address this gap, we conducted an fMRI study in which female and male participants encoded pictures of familiar scenes (e.g., an airport picture) and later recalled them, while rating the vividness of their visual recall. Outside the scanner, participants had to distinguish each seen scene from three similar lures (e.g., three airport pictures). We modeled the sensory and categorical visual features of multiple scenes using both early and late layers of a deep convolutional neural network. Then, we applied representational similarity analysis to determine which brain regions represented stimuli in accordance with the sensory and categorical models. We found that categorical, but not sensory, representations predicted subsequent memory. In line with the previous result, only for the categorical model, the average recognition performance of each scene exhibited a positive correlation with the average visual dissimilarity between the item in question and its respective lures. These results strongly suggest that even in memory tests that ostensibly rely solely on visual cues (such as forced-choice visual recognition with similar distractors), memory decisions for scenes may be primarily influenced by categorical rather than sensory representations.

Your place or mine? The neural dynamics of personally familiar scene recognition suggests category independent familiarity encoding.

Recognizing a stimulus as familiar is an important capacity in our everyday life. Recent investigation of visual processes has led to important insights into the nature of the neural representations of familiarity for human faces. Still, little is known about how familiarity affects the neural dynamics of non-face stimulus processing. Here we report the results of an EEG study, examining the representational dynamics of personally familiar scenes. Participants viewed highly variable images of their own apartments and unfamiliar ones, as well as personally familiar and unfamiliar faces. Multivariate pattern analyses were used to examine the time course of differential processing of familiar and unfamiliar stimuli. Time-resolved classification revealed that familiarity is decodable from the EEG data similarly for scenes and faces. The temporal dynamics showed delayed onsets and peaks for scenes as compared to faces. Familiarity information, starting at 200ms, generalized across stimulus categories and led to a robust familiarity effect. In addition, familiarity enhanced category representations in early (250-300ms) and later (>400ms) processing stages. Our results extend previous face familiarity results to another stimulus category and suggest that familiarity as a construct can be understood as a general, stimulus-independent processing step during recognition.

Conscious and unconscious memory and eye movements in context-guided visual search: A computational and experimental reassessment of Ramey, Yonelinas, and Henderson (2019)

Are eye movements unconsciously guided towards target locations in familiar scenes? In a recent eyetracking study, Ramey, Yonelinas, and Henderson (2019) measured eye-movement efficiency (scanpath ratio) and memory judgments when participants searched for targets in repeated and novel scenes. When trials judged new with high confidence were selected, scanpath ratio was lower for old scenes (misses) than for new scenes (correct rejections). In addition, familiarity as measured by recognition confidence did not significantly predict scanpath ratio. Ramey et al. attributed these results to unconscious learning guiding eye movements. In a re-assessment of Ramey et al.’s data, we show that their findings can be accounted for by a single-system computational model in which eye movements and memory judgments are driven by a common latent memory representation. In particular, (a) the scanpath ratio difference between high-confidence misses and correct rejections is a consequence of regression to the mean, while (b) the null correlation between familiarity and scanpath ratio, partly a natural consequence of the low reliability of the scanpath ratio measure, is also reproduced by the model. Two pre-registered experiments confirm a novel prediction of the alternative single-system model. This work offers a parsimonious account of Ramey et al.’s findings without recourse to unconscious guidance of eye movements.

Preferential signal pathways during the perception and imagery of familiar scenes: An effective connectivity study.

The perception and imagery of landmarks activate similar content-dependent brain areas, including occipital and temporo-medial brain regions. However, how these areas interact during visual perception and imagery of scenes, especially when recollecting their spatial location, remains unknown. Here, we combined functional magnetic resonance imaging (fMRI), resting-state functional connectivity (rs-fc), and effective connectivity to assess spontaneous fluctuations and task-induced modulation of signals among regions entailing scene-processing, the primary visual area and the hippocampus (HC), responsible for the retrieval of stored information. First, we functionally defined the scene-selective regions, that is, the occipital place area (OPA), the retrosplenial complex (RSC) and the parahippocampal place area (PPA), by using the face/scene localizer, observing that two portions of the PPA-anterior and posterior PPA-were consistently activated in all subjects. Second, the rs-fc analysis (n = 77) revealed a connectivity pathway similar to the one described in macaques, showing separate connectivity routes linking the anterior PPA with RSC and HC, and the posterior PPA with OPA. Third, we used dynamic causal modelling to evaluate whether the dynamic couplings among these regions differ between perception and imagery of familiar landmarks during a fMRI task (n = 16). We found a positive effect of HC on RSC during the retrieval of imagined places and an effect of occipital regions on both RSC and pPPA during the perception of scenes. Overall, we propose that under similar functional architecture at rest, different neural interactions take place between regions in the occipito-temporal higher-level visual cortex and the HC, subserving scene perception and imagery.

Between Biblical and Political: The Subversion of Samson in Twelfth-Century León-Castile

The region of Palencia in northern Spain straddled an unstable border between medieval kingdoms. Within this territory of shifting allegiances, a group of churches features a curious variant of a common motif, traditionally identified as Samson fighting the lion. Carved capitals inside each church depict the familiar scene of a man wrestling a lion. However, in this Palencian group, additional assailants aggressively besiege the beast from both sides. The demise of the lion—its fearsome jaws wrenched open and rendered useless, claws immobilized, and tail severed by a sharp blade—overshadows the triumph of the hero. The iconographic variant, which proliferated across northern Palencia around the year 1200, seems to communicate a partisan message promulgated in the local community. The lion, representing the kingdom of León, is one of the earliest examples of heraldry, with the beast’s body serving as a proxy for the king’s body in visual culture. In this border zone between the warring kingdoms of León and Castile, the iconographical departure offers a political commentary, denouncing León as an enemy of the Church.

Mastering Emotions: Feelings, Power, and Slavery in the United States by Erin Austin Dwyer

Reviewed by: Mastering Emotions: Feelings, Power, and Slavery in the United States by Erin Austin Dwyer Lindsay A. Silver Mastering Emotions: Feelings, Power, and Slavery in the United States. By Erin Austin Dwyer. America in the Nineteenth Century. (Philadelphia: University of Pennsylvania Press, 2021. Pp. x, 284. $39.95, ISBN 978-0-8122-5339-9.) In Mastering Emotions: Feelings, Power, and Slavery in the United States, Erin Austin Dwyer insightfully demonstrates how emotions shaped, maintained, and challenged the institution of slavery by examining the power dynamics of real and performative feelings between people who were enslaved and slave owners. At the same time, Dwyer emphasizes the prominence of emotions in proslavery defenses and abolitionist critiques, further underscoring the centrality of sentiments to many of the arguments seeking to uphold or destroy slavery in antebellum America. As a book about the power of emotions and feelings, Mastering Emotions primarily focuses on relationships between enslaved people and slaveholders. Dwyer draws on a wide variety of sources while making particular use of first-person accounts. These sources, which include slave narratives alongside the journals and diaries of white southerners who owned enslaved people, enable Dwyer to expose and explore the feelings and emotions that established, maintained, and even challenged the power dynamics within slavery. Dwyer’s work is deeply rooted in an extensive historiography of American slavery that acknowledges the prevalence of such sentiments among enslaved Blacks and slaveholding whites. What stands out about Mastering Emotions is that Dwyer is the first to seriously and methodically analyze the significance of feelings and emotions to the institution of slavery. Dwyer accomplishes this goal by applying the framework established by scholars of the history of emotions to the history of American slavery. As a result, the reader revisits many familiar scenes and stories from nineteenth-century narratives of enslaved people and slaveholders, but with a new understanding of how power dynamics operated between them, due to Dwyer’s emphasis on the importance of emotions in these relationships. Mastering Emotions covers considerable ground, examining a number of emotions from multiple angles and perspectives. Dwyer successfully demonstrates how the roles of enslaved persons and slave owners were culturally constructed, learned, reinforced, and challenged through emotions both real and performative. Included in the wide range of emotions Dwyer examines are trust, happiness, fear, and the enjoyment of freedom. In her discussion of fear and punishment, the author highlights how scholars have traditionally focused on physical punishment inflicted on enslaved people and have ignored or downplayed the role of emotional or affective discipline. By shifting the focus away from physical punishment and examining the role of emotions, Dwyer successfully demonstrates a greater understanding of “the lived experience of slavery and . . . the critical place of emotional mastery in discipline” (p. 139). Additionally, Dwyer exposes the contradictions in proslavery literature that argued that enslaved people did not have the capacity to feel emotions as strongly as white people, even as emotional punishments designed to break up enslaved families became a common form of control—one that enslaved people often felt was much more painful than physical violence. [End Page 142] In order to fully demonstrate the significance, power, and legacy of the emotional politics of slavery, Dwyer concludes with a brief but important overview of how emotions have shaped Black and white race relations in America since emancipation. In doing so, Dwyer outlines how different emotions, particularly fear, have tragically impacted the joys of freedom for Black Americans from the Jim Crow era to the present. Importantly, Dwyer’s conclusion makes a strong case for further academic and cultural work to better understand the power dynamics of emotions within race relations since the abolition of slavery more than 150 years ago.

The effect of target-related and target-irrelevant novel stimuli on response behaviour

Novel events catch our attention, which can influence performance of a task. Whether this attentional capture by novelty benefits or impairs performance depends on several factors, such as the relevance of the stimulus, task requirements, and the timing of the event. Additionally, it has been argued that novel stimuli can hold intrinsic reward value, which may directly affect approach motivation, similar to positive valence stimuli. This link between novelty and approach/avoid behaviour has not been investigated directly. Here, we investigated whether stimulus novelty interacts with response behaviour in an approach/avoidance task, and whether these effects depend on the task relevance of novelty and stimulus timing. In experiment 1, participants gave an approach or avoid response dependent on a shape (diamond or square) presented at different stimulus onset asynchronies (SOA) following a novel or familiar scene (target-irrelevant novelty). In experiment 2, participants had to approach or avoid a novel or familiar image depending on the content (indoor/outdoor; target-related novelty). A shape was presented at different SOA. Results of a linear mixed model showed novelty-induced performance costs as demonstrated by longer RT and lower accuracy when novelty was target-relevant, likely due to attentional lingering at novel images. When images were target-irrelevant, approach but not avoid responses were faster for familiar versus novel images at 200 ms SOA only. Thus, novelty had a differentially pronounced detrimental effect on performance. These observations confirm that processing of novel stimuli generally depends on stimulus relevance, and tentatively suggests that differential processing of novel and familiar images is intensified by motivated approach behaviour.

Re-reading the Archive: A 21st Century Re-appraisal of Kurosawa’s "The Bad Sleep Well" as a Modern "Hamlet"

Among Japanese film director Kurosawa Akira’s three Shakespeare films, Throne of Blood (1957), Ran (1985), and The Bad Sleep Well (1960), the latter has been relatively ignored in Anglophone Shakespeare criticism. This article investigates the Anglophone reception of The Bad Sleep Well and argues in favor of its re-appraisal as a Hamlet. On reception, it examines three explanations for the neglect: its modern setting, its deconstructive adaptation, and its cinematic quality. Considering the latter unconvincing, the article posits that the first two were only detrimental to the film’s reception because they respectively did not conform to Western expectations of essentially pre-modern ‘Oriental’ Japan and of ‘straight’ canonical Shakespeare. Considering changed attitudes in Shakespeare studies, neither of these should still be held against the film. On re-appraisal, The Bad Sleep Well may be reread in the 21st century as part of our continuing memory of our global Shakespeare discourse. Centering on the film’s innovative presentation of Claudius and The Mousetrap, the article argues for the porous border between ‘straight’ production and ‘crooked’ adaptation, and the value to the tradition of oblique approaches to familiar scenes and characters. By arguing for The Bad Sleep Well as a Hamlet worthy of study, the article furthers discussion on archival silences and new rhizomatic models of global Shakespeare that seek to move past the more reductive qualities of the ‘national Shakespeares’ mode of discourse that dominated in the 1990s and 2000s.

The extent and specificity of visual exploration determines the formation of recollected memories in complex scenes.

Our visual memories of complex scenes often appear as robust, detailed records of the past. Several studies have demonstrated that active exploration with eye movements improves recognition memory for scenes, but it is unclear whether this improvement is due to stronger feelings of familiarity or more detailed recollection. We related the extent and specificity of fixation patterns at encoding and retrieval to different recognition decisions in an incidental memory paradigm. After incidental encoding of 240 real-world scene photographs, participants (N = 44) answered a surprise memory test by reporting whether an image was new, remembered (indicating recollection), or just known to be old (indicating familiarity). To assess the specificity of their visual memories, we devised a novel report procedure in which participants selected the scene region that they specifically recollected, that appeared most familiar, or that was particularly new to them. At encoding, when considering the entire scene,subsequently recollected compared to familiar or forgotten scenes showed a larger number of fixations that were more broadly distributed, suggesting that more extensive visual exploration determines stronger and more detailed memories. However, when considering only the memory-relevant image areas, fixations were more dense and more clustered for subsequently recollected compared to subsequently familiar scenes. At retrieval, the extent of visual exploration was more restricted for recollected compared to new or forgotten scenes, with a smaller number of fixations. Importantly, fixation density and clustering was greater in memory-relevant areas for recollected versus familiar or falsely recognized images. Our findings suggest that more extensive visual exploration across the entire scene, with a subset of more focal and dense fixations in specific image areas, leads to increased potential for recollecting specific image aspects.

The four friends spend their Saturdays racing through the neighborhood under the watchful eye of Jay's grandfather, who regales them with stories of famous Black athletes. Jay's impatient to grow, but as his height ticks up along the wall and he's allowed a bit more independence, he notices he's getting more warnings than stories from his grandfather and the other adults in his life. In a painful but likely familiar scene to Black households, the grown-ups sit him down, and the story here spills into a wordless scene, smudged in blues and grays, depicting overt, racist aggression against Black people, from being yelled at in a store to handcuffed by police.

Neural rendering in a room

We, as human beings, can understand and picture a familiar scene from arbitrary viewpoints given a single image, whereas this is still a grand challenge for computers. We hereby present a novel solution to mimic such human perception capability based on a new paradigm of amodal 3D scene understanding with neural rendering for a closed scene. Specifically, we first learn the prior knowledge of the objects in a closed scene via an offline stage, which facilitates an online stage to understand the room with unseen furniture arrangement. During the online stage, given a panoramic image of the scene in different layouts, we utilize a holistic neural-rendering-based optimization framework to efficiently estimate the correct 3D scene layout and deliver realistic free-viewpoint rendering. In order to handle the domain gap between the offline and online stage, our method exploits compositional neural rendering techniques for data augmentation in the offline training. The experiments on both synthetic and real datasets demonstrate that our two-stage design achieves robust 3D scene understanding and outperforms competing methods by a large margin, and we also show that our realistic free-viewpoint rendering enables various applications, including scene touring and editing. Code and data are available on the project webpage: https://zju3dv.github.io/nr_in_a_room/.

Novelty-Related fMRI Responses of Precuneus and Medial Temporal Regions in Individuals at Risk for Alzheimer Disease

Background and ObjectivesWe assessed whether novelty-related fMRI activity in medial temporal lobe regions and the precuneus follows an inverted U-shaped pattern across the clinical spectrum of increased Alzheimer disease (AD) risk as previously suggested. Specifically, we tested for potentially increased activity in individuals with a higher AD risk due to subjective cognitive decline (SCD) or mild cognitive impairment (MCI). We further tested whether activity differences related to diagnostic groups were accounted for by CSF markers of AD or brain atrophy.MethodsWe studied 499 participants aged 60–88 years from the German Center for Neurodegenerative Diseases Longitudinal Cognitive Impairment and Dementia Study (DELCODE) who underwent task-fMRI. Participants included 163 cognitively normal (healthy control, HC) individuals, 222 SCD, 82 MCI, and 32 patients with clinical diagnosis of mild AD. CSF levels of β-amyloid 42/40 ratio and phosphorylated-tau181 were available from 232 participants. We used region-based analyses to assess novelty-related activity (novel > highly familiar scenes) in entorhinal cortex, hippocampus, and precuneus as well as whole-brain voxel-wise analyses. First, general linear models tested differences in fMRI activity between participant groups. Complementary regression models tested quadratic relationships between memory impairment and activity. Second, relationships of activity with AD CSF biomarkers and brain volume were analyzed. Analyses were controlled for age, sex, study site, and education.ResultsIn the precuneus, we observed an inverted U-shaped pattern of novelty-related activity across groups, with higher activity in SCD and MCI compared with HC, but not in patients with AD who showed relatively lower activity than MCI. This nonlinear pattern was confirmed by a quadratic relationship between memory impairment and precuneus activity. Precuneus activity was not related to AD biomarkers or brain volume. In contrast to the precuneus, hippocampal activity was reduced in AD dementia compared with all other groups and related to AD biomarkers.DiscussionNovelty-related activity in the precuneus follows a nonlinear pattern across the clinical spectrum of increased AD risk. Although the underlying mechanism remains unclear, increased precuneus activity might represent an early signature of memory impairment. Our results highlight the nonlinearity of activity alterations that should be considered in clinical trials using functional outcome measures or targeting hyperactivity.

Natural Scene Virtual Reality as a Behavioral Health Countermeasure in Isolated, Confined, and Extreme Environments: Three Isolated, Confined, Extreme Analog Case Studies.

Isolated, confined, extreme (ICE) environments are accompanied by a host of stress-inducing circumstances: operational pressure, interpersonal dynamics, limited communication with friends and family, and environmental hazards. We evaluated the effectiveness of attention-restoration-therapy-based immersive Virtual Reality (VR) in three ICE environments: the Canadian Forces Station-Alert (CFS Alert), the 12-month HI-SEAS IV expedition, and the 8-month HI-SEAS V expedition. Thirty-one individuals (29 male, 2 female) at CFS Alert, and 12 total crewmembers (7 male, 5 female, six crewmembers per sessions) at HI-SEAS participated. All participants viewed immersive VR scenes, but scene content varied by deployment. Data collection included pre- and post-intervention surveys and semi-structured post-mission interviews. Survey data were analyzed by scene content within each analog using nonparametric approaches. Acceptability and desirability of the VR content varied significantly by ICE analog, as well as by participants within a given analog. The two initial exploratory protocols enabled a more directed study in HI-SEAS V to identify the importance of differences in scene content. Use and perceived utility of the VR varied considerably across participants, indicating that psychological support needs to be individualized. Overall, natural scene VR was broadly considered restorative, but after long periods of isolation, dynamic and familiar scenes including those with people were also appealing. Immersive, nature-based VR was highly valued by some, but not all participants, suggesting that this intervention tool holds promise for use in ICE settings but needs to be tailored to the setting and individual.

Lost items and exposed shame – dreamcore’s inheritance and transcendence of liminal space and defamiliarization

ABSTRACT Dreamcore originates from a video (or image) form submitted on 21 April 2018, when an anonymous user posted a thread on 4chan’s paranormal section collecting images that would make people feel ‘uncomfortable', and another user’s comment under it gained the attention of the community. And it has been a new subculture that uses familiar scenes to make the audience nostalgic but uneasy, with two important characteristics: ‘Lost items’ and ‘exposed shame’. In contrast to the philosophical concept ‘sense of material’, the absolutely independent defamiliarization, or liminal space’s ‘neither … nor … ’, ‘lost items’ pursues the familiarity in strangeness without resorting to the expression of magical reality, or using ambiguity between the two to create a ‘either … or …’ atmosphere; Compared with modern urban planning based on the principle of ‘ecology’, ‘exposed shame’ reveals infrastructures that do not match the natural setting in the image, causing abruptness and embarrassment. Both point to the dreamcore’s playful ambiguity, thus not being governed by serious art and symbolising the original intention of free creation.

Nocturnal enuresis: A nightmare to mothers

Nocturnal eneuresis is also known as Bed-wetting or Night time incontinence. It is the involuntary urination while sleeping after the age at which staying dry at night can be reasonably expected by the parents. Soggy sheets and pants and an embarrassed child are a familiar scene in many homes. But there is no need to be in despair. Nocturnal eneuresis cannot be considered as a sign of toilet training gone wrong or bad. It's just a normal part of the development of children. Generally, nocturnal eneuresis before the age of seven isn't a big concern. At this age, night time bladder control may still be developing in the child. If nocturnal eneuresis continues, the problem should be treated or handled with patience and understanding. Changes in lifestyle, bladder training, moisture alarms and sometimes medication may help in the reduction of nocturnal eneuresis.
