RESUMO

BACKGROUND: Children spend a significant amount of time engaging in sedentary behaviors, defined as activities that do not increase energy expenditure significantly above resting levels, such as watching TV and playing PC/video games. Increased screen time is a significant public health concern because children are in a developmental stage where lifestyle behaviors predict various health outcomes in adulthood and beyond. This study explores the links between parent-child attachment, ego resilience, and children's screen time. METHODS: This cross-sectional correlation study uses 1,163 parents and their children data from the 12th Panel Survey of Korean Children. The study instruments were a modified Armsden and Greenberg scale of parent-child attachment and modified the children's ego resilience scale of the Block and Kremen. Children's screen time was classified as more than 2 h per day spent watching television, playing on computers, or playing video games in their leisure time. RESULTS: Study results show a negative association between father-child attachment and children's screen time (ß = -0.43, p < .001) and a positive association between father-child attachment and ego resilience (ß = 0.24, p < .001). Ego resilience showed a negative link to children's screen time after adjusting for parental attachment (ß =- 0.03, p = .009). Father-child attachment link to children's screen time (ß = -0.36, p < .001) continued even though the association was slightly reduced in magnitude after adjusting for ego resilience. CONCLUSIONS: Our findings show the mediating role of ego resilience on a negative path of father-child attachment to children's screen time. This finding emphasizes the importance of fostering solid father-child relationships and enhancing children's psychological resilience as critical strategies for reducing excessive screen time. By addressing emotional support and resilience-building, interventions can more effectively promote healthier behavioral outcomes in children.

RESUMO

Robotics can play a useful role in the scientific understanding of the sense of self, both through the construction of embodied models of the self and through the use of robots as experimental probes to explore the human self. In both cases, the embodiment of the robot allows us to devise and test hypotheses about the nature of the self, with regard to its development, its manifestation in behavior, and the diversity of selves in humans, animals, and, potentially, machines. This paper reviews robotics research that addresses the topic of the self-the minimal self, the extended self, and disorders of the self-and highlights future directions and open challenges in understanding the self through constructing its components in artificial systems. An emerging view is that key phenomena of the self can be generated in robots with suitably configured sensor and actuator systems and a layered cognitive architecture involving networks of predictive models.

RESUMO

We examined the connections that narcissistic and borderline personality traits had with hypothetical responses to romantic infidelity in a sample of Israeli community members (N = 997). We distinguished between four forms of narcissism: extraverted narcissism (characterized by assertive self-enhancement), antagonistic narcissism (characterized by defensiveness and hostility), neurotic narcissism (characterized by emotional distress), and communal narcissism (characterized by attempts to emphasize superiority over others by exaggerating communal characteristics such as being extraordinarily helpful). We also measured levels of borderline personality traits. Results showed that neurotic narcissism was strongly associated with heightened negative emotional responses, particularly in high-threat infidelity scenarios, aligning with predictions regarding emotional volatility. Antagonistic and communal narcissism showed detrimental effects on relationship evaluations primarily under low-threat conditions, indicating distinct patterns of defensiveness and vulnerability. Extraverted narcissism showed no significant association with emotional responses. Borderline traits were linked to intense emotional reactions across conditions, emphasizing their broad impact on perceived relational threats. These findings suggest that while some personality traits exacerbate reactions in less severe conditions, infidelity trauma can overwhelm these differences, underscoring the potential need for personalized therapeutic approaches. Discussion is focused on the implications for understanding personality traits in relational contexts and future research directions exploring varied threat manipulations.

RESUMO

This paper explores the mechanisms that lead to a destructive tendency in the formation and functioning of the psychic apparatus, to the characteristic states of subjects who are drawn to non-life. The dynamics of the primary mother-child relationship involve a structural interaction between mind and body, subject and object. The dialectic between the life drive and the death drive is conceptualized as the structuring of homeostatic dynamic equilibria, in which both drives belong to the living, provided they are kept in a non-isolated system. This conception has analogies with other disciplines that have changed their paradigms, such as neurobiology, which, for living beings in open systems, hypothesises a continuous interconnected Becoming of undivided separation and of discontinuity. In unitary psyche-soma functioning, a dynamic homoeostatic balance marks the state of health of the relating subject; or if, instead, the system is isolated, a pathological dysregulation depending on the emotional-affective vicissitudes it undergoes. Two clinical cases illustrate these dynamics. For this tendency on the level of the somatopsychic unit, the name alloiosis has been put forward, in analogy with cellular apoptosis.

RESUMO

The concept of basic Self-disorders (SD) captures the experiential aspects associated with vulnerability to schizophrenia spectrum disorders (SSD). SD emerge prior to, and constitute the underlying structure for, the emergence of major diagnostic symptoms, including positive psychotic ones. SD are also detectable in populations with familial risk for SSD. This paper proposes a two-stage phenomenological-developmental model, exploring the early deficit in multisensory integration and their impact on the ontogeny of the Minimal Self in the first years of life. It also examines subsequent emergence of schizotaxic vulnerability, which later manifests as typical anomalies of subjectivity, such as basic symptoms and self-disorders.

RESUMO

There are many studies in Psychology and other sciences about the concept of power. We believe that individual power is one of the most critical factors in human motivation, which is considered by prominent motivation theories, like Choice Theory or McClelland's Human Motivation Theory. This paper aims to study the concept of power, considering ego and social orientation. The extensive literature review allowed us to describe the concepts related to those orientations and to induce a theoretical model that may typify and explain the relationships between the two perspectives of power. The model might contribute to describing four motivational profiles, namely the imperator, with high ego-power and power over others orientation; the supporter, with low ego-power and power with other orientation; the leader, with high ego-power and power with others orientation; and the controller, with low ego-power and power over others orientation. The Ego-Social Power Motivation Model could help describe the power signature of an individual. This individual picture might help psychologists work on motivations, attitudes, and behaviours to enhance people's lives and well-being.

RESUMO

A single dose of psilocybin, a psychedelic that acutely causes distortions of space-time perception and ego dissolution, produces rapid and persistent therapeutic effects in human clinical trials1-4. In animal models, psilocybin induces neuroplasticity in cortex and hippocampus5-8. It remains unclear how human brain network changes relate to subjective and lasting effects of psychedelics. Here we tracked individual-specific brain changes with longitudinal precision functional mapping (roughly 18 magnetic resonance imaging visits per participant). Healthy adults were tracked before, during and for 3 weeks after high-dose psilocybin (25 mg) and methylphenidate (40 mg), and brought back for an additional psilocybin dose 6-12 months later. Psilocybin massively disrupted functional connectivity (FC) in cortex and subcortex, acutely causing more than threefold greater change than methylphenidate. These FC changes were driven by brain desynchronization across spatial scales (areal, global), which dissolved network distinctions by reducing correlations within and anticorrelations between networks. Psilocybin-driven FC changes were strongest in the default mode network, which is connected to the anterior hippocampus and is thought to create our sense of space, time and self. Individual differences in FC changes were strongly linked to the subjective psychedelic experience. Performing a perceptual task reduced psilocybin-driven FC changes. Psilocybin caused persistent decrease in FC between the anterior hippocampus and default mode network, lasting for weeks. Persistent reduction of hippocampal-default mode network connectivity may represent a neuroanatomical and mechanistic correlate of the proplasticity and therapeutic effects of psychedelics.

RESUMO

This paper discusses the ways in which psychoanalytic perspectives may have been limited by the Western cultural context in which they originated and explores the potential of the Indian cultural imagination to broaden psychoanalytic thinking about ego formation, the nature of Eros, bisexuality, and individuation. The case is made for the need to retain the diverse perspectives offered by the cultural imaginations of different civilisations despite the globalization of ideas.

RESUMO

In this comment paper on von Fircks (2023a), I would like to focus on four issues and offer some reflections on them: first, what is happening in the process of a new I arising through mindfulness meditation practice? I would like to supplement the dialogue between Buber and Rogers in 1957 on the dynamism of I and Me, which is the basis of Mead's theory of self formation, in which I and Me separate, discover and meet a new self. The second, is that meditation, which at first glance appears to be an internal meditation practice and a personal activity, leads to a semiotic mediated social process. The Tao and early Buddhist ideas that form the background to the experiential process of mindfulness meditation will be reviewed, and the significance of people experiencing the interdependence of non-human nature and the environment through the practice will be discussed. Third, connecting this to the idea of Umwelt (Uexküll) and the semiosphere (Lotman), an attempt is made to extend the otherness as a collating body of self formation to Umwelt. Fourth, mindfulness meditation focuses attention on the breath. In relation to Mead's focus on the environment under the skin, i.e. corporeality, I will supplement the psychological meaning of cultivating the body's sense of interoception through the sensing of repetitive movements of tension and relaxation. Through the above, what kind of semiotic mediating function does mindfulness meditation have in relation to the construction of the new I, and how does it lead to the creation of social meaning? We would like to discuss these points. CLINICAL TRIAL REGISTRATION: The article does not contain any studies with clinical trial. This, clinical Trial registration is not applicable.

RESUMO

Ego-depletion describes a state of mind, where the capacity for self-control is temporarily depleted after a primary self-control action. The aim of this study was to investigate whether a brief virtual reality-based mindfulness breathing meditation with integrated biofeedback can be considered an effective strategy to counteract the detrimental effects of ego depletion on motor skill performance under pressure. The study included two experiments, each of them designed as counterbalanced cross-over trials and based on an a priori sample-size calculation. Within each experiment, participants completed two appointments in a randomly assigned order, during which they were asked to perform 20 basketball free throws (N = 18; Experiment 1) or 20 penalty kicks at a football goal in four target squares (N = 16; Experiment 2) under pressure pre and post the following conditions: Stroop-test-induced ego depletion followed by a 15 min resting break, Stroop-test-induced ego depletion followed by a 15 min virtual reality-based mindfulness breathing meditation with integrated biofeedback. Results indicate that, in comparison to a resting break, a brief virtual reality-based mindfulness meditation with integrated biofeedback can counteract the detrimental effects of ego-depletion (Experiment 2) and enhance motor skill performance under pressure (Experiment 1, 2) Implications for researchers and practitioners are derived in light of the identified methodological limitations.

RESUMO

Vaccine hesitancy is an inevitable risk for societies as it contributes to outbreaks of diseases. Prior research suggests that vaccination decisions of individuals tend to spread within social networks, resulting in a tendency to vaccination homophily. The clustering of individuals resistant to vaccination can substantially make the threshold necessary to achieve herd immunity harder to reach. In this study, we examined the extent of vaccination homophily among social contacts and its association with vaccine uptake during the COVID-19 pandemic in Hungary using a contact diary approach in two cross-sectional surveys. The results indicate strong clustering among both vaccinated and unvaccinated groups. The most powerful predictor of vaccine uptake was the perceived vaccination rate within the egos' social contact network. Vaccination homophily and the role of the interpersonal contact network in vaccine uptake were particularly pronounced in the networks of close relationships, including family, kinship, and strong social ties of the ego. Our findings have important implications for understanding COVID-19 spread dynamics by showing that the strong clustering of unvaccinated individuals posed a great risk in preventing the spread of the disease.

RESUMO

The issue of academic procrastination is highly prevalent among university students. It not only has a deterimental effect on students' academic performance but also poses a risk to their physical and mental well-being. Anxiety, as a negative emotion, has attracted researchers' attention in relation to academic procrastination. Research indicates a correlation between state anxiety and academic procrastination, but the underlying mechanisms that drive this association remain unclear. When individuals experience ego-depletion, it can lead to psychological exhaustion, subsequently leading to procrastination. Gender role conceptions, shaped by sociocultural and psychological mechanisms, have profound implications on individuals' cognition, emotions, and behaviors. This study primarily aims to explore the relationship between state anxiety and academic procrastination among university students, with a particularly focus on the mediating role of ego-depletion and the moderating role of gender. A survey using the State Anxiety Scale, Ego-Depletion Scale, and Irrational Procrastination Scale was administered to 3370 undergraduates. State anxiety shows positive correlations with ego depletion and academic procrastination (r = 0.665, p < 0.01; r = 0.491, p < 0.01), while ego depletion is also positively linked to academic procrastination (r = 0.500, p < 0.01). State anxiety serves as a positive predictor of academic procrastination, with a confidence interval of 95% [0.626, 0.696]; additionally, ego depletion partially mediates the relationship between state anxiety and academic procrastination, with a confidence interval of 95% [0.168, 0.251]. Gender acts as a moderator in directly predicting the impact of state anxiety on academic procrastination and in the latter stage of mediating the effect of ego depletion. State anxiety can significantly and positively predict academic procrastination among university students. Ego-depletion partially mediates the relationship between state anxiety and academic procrastination. The direct predictive effect of state anxiety on academic procrastination, as well as the mediating role of ego-depletion, is moderated by gender. This provides educators and university students themselves with reference for addressing the issue of academic procrastination.

RESUMO

Somewhat questioning Elizabeth Spelke's attempt to account for infants' social knowledge, our commentary argues that social cognition might be divided into several specialized systems. In addition to the core system dedicated to the intersubjective dimension of close relationships, infants could be prewired to process social relationships, such as dominance, characterized by their impersonal, normative dimension.

RESUMO

Out-of-body experiences (OBEs) are subjective phenomena during which individuals feel disembodied or perceive themselves as outside of their physical bodies, often resulting in profound and transformative effects. In particular, experiencers report greater heightened pro-social behavior, including more peaceful relationships, tolerance, and empathy. Drawing parallels with the phenomenon of ego dissolution induced by certain psychedelic substances, we explore the notion that OBEs may engender these changes through ego dissolution, which fosters a deep-seated sense of unity and interconnectedness with others. We then assess potential brain mechanisms underlying the link between OBEs and empathy, considering the involvement of the temporoparietal junction and the Default Mode Network. This manuscript offers an examination of the potential pathways through which OBEs catalyze empathic enhancement, shedding light on the intricate interplay between altered states of consciousness and human empathy.

RESUMO

This study examined the relationship between trauma, ego functioning, and internet addiction. We recruited 323 participants via Amazon Mechanical Turk, a crowdsourcing platform that can be used for survey research. We gave participants the Internet Addiction Test, the Life Events Checklist, the Ego Function Assessment questionnaire, and a demographic questionnaire. Our results indicate that 41.5% reported no internet addiction, with the majority of our sample reporting behaviors that were consistent with internet addiction: mild internet addiction = 37.8%, moderate internet addiction = 19.8%, and severe internet addiction = 0.9%. The constrictive factor of ego functioning was significantly worse in those with internet addiction. Path analysis showed that the constrictive factor of ego functioning partially mediated the relationship between a self-reported history of trauma and the presence of self-reported internet addiction.

RESUMO

Previous research has suggested that math anxiety may contribute to poor math performance by interfering with working memory. However, only a limited number of studies investigated the mediating role of working memory in the math anxiety-math performance link in school-aged children. Unlike math anxiety, ego-resiliency is a personality resource that promotes the management of challenges and has been positively associated with math performance and negatively with anxiety. Nevertheless, there is still limited understanding regarding the specific role of ego-resiliency in math learning and how it relates to math anxiety. This study aimed to investigate conjunctly the interplay between primary school children's ego-resiliency, math anxiety, working memory, and performance on two different math tasks (i.e., arithmetic task and word problem-solving task), after controlling for general anxiety and age. The study involved 185 Italian children from grades 3 to 5. Serial multi-mediational analyses revealed that: (1) ego-resiliency has a positive indirect effect on math achievement through two paths - math anxiety, and math anxiety and working memory; (2) the study replicated previous findings showing that working memory partially mediated the relationship between math anxiety and math performance; (3) similar patterns of results were found for both math skills. The study identifies ego-resiliency as a possible protective factor in the development of math anxiety and suggests that ego-resiliency could be worth considering when designing interventions aimed at reducing negative emotions towards mathematics.

RESUMO

Schizophrenia continues its resistance to the pathogenetic understanding. We believe that one of the reasons is an oblivion of schizophrenia's characteristic Gestalt expressive of its psychopathological structure. In this article we argue for a crucial role of disorders of selfhood in the constitution of this Gestalt. First, we present a phenomenological account of the self. This is followed by an exposition of basic complaints in schizophrenia which are reflective of a disordered selfhood and which often date back to childhood. We then present characteristic features of the schizophrenic psychosis with its phenomenon of "double bookkeeping". Hallucinations, delusions and double bookkeeping are all associated with the instability of the self. Finally, we briefly address characteristic aspects of the encounter with a schizophrenia patient and argue that self-disorders play an important diagnostic role. We conclude by emphasizing the role of phenomenology in psychiatric research.

RESUMO

Temporary reductions in self-control due to previous cognitive effort, also known as 'ego depletion', have been shown to negatively impact performance in subsequent tasks requiring self-control. Various theoretical accounts suggest that high levels of task motivation may prevent negative behavioural effects of ego depletion. Against this background, the current study performed a conceptual replication of a previous study examining the effects of ego depletion on sprint start performance (i.e., Englert et al., 2015) and implemented additional monetary incentives to manipulate task motivation. Using a pretest-intervention-posttest design, ninety-six novice sprinters performed a sprinting task that required them to complete a series of 20-m sprints. In between pretest and posttest, participants performed a letter writing task either under high cognitive demand (depletion group) or low cognitive demand (non-depletion control group). Subsequently, and prior to starting the posttest, participants were presented either with a monetary incentive or no incentive. Manipulation checks confirmed that the letter writing task successfully manipulated perceived regulatory demand and that task motivation at the posttest was higher for participants who were offered a monetary incentive. The number of false starts decreased significantly with ego depletion, while sprint start reaction times and sprint finish times remained unaffected. Regardless of ego depletion, sprint finish times significantly improved with monetary incentives. These results suggest that brief engagement in a demanding cognitive task is unlikely to impair novice sprinters' ability to self-regulate during the start of a subsequent, maximal sprinting effort for which they are highly motivated.

RESUMO

The purpose of the present article is to consider schizophrenia-the very idea-from the perspective of phenomenological psychopathology, with special attention to the problematic nature of the diagnostic concept as well as to the prospect and challenges inherent in focusing on subjective experience. First, we address historical and philosophical topics relevant to the legitimacy of diagnostic categorization-in general and regarding "schizophrenia" in particular. William James's pragmatist approach to categorization is discussed. Then we offer a version of the well-known basic-self or ipseity-disturbance model (IDM) of schizophrenia, but in a significantly revised form (IDMrevised). The revised model better acknowledges the diverse and even seemingly contradictory nature of schizophrenic symptoms while, at the same time, interpreting these in a more unitary fashion via the key concept of hyperreflexivity-a form of exaggerated self-awareness that tends to undermine normal world-directedness and the stability of self-experience. Particular attention is paid to forms of exaggerated "self-presence" that are sometimes neglected yet imbue classically schizophrenic experiences involving subjectivism or quasi-solipsism and/or all-inclusive or ontological forms of paranoia. We focus on the distinctively paradoxical nature of schizophrenic symptomatology. In concluding we consider precursors in the work of Klaus Conrad, Kimura Bin and Henri Grivois. Finally we defend the concept of schizophrenia by considering its distinctive way of altering certain core aspects of the human condition itself.
