Characteristics of memories for near-death experiences

Near-death experiences are vivid, life-changing experiences occurring to people who come close to death. Because some of their features, such as enhanced cognition despite compromised brain function, challenge our understanding of the mind-brain relationship, the question arises whether near-death experiences are imagined rather than real events. We administered the Memory Characteristics Questionnaire to 122 survivors of a close brush with death who reported near-death experiences. Participants completed Memory Characteristics Questionnaires for three different memories: that of their near-death experience, that of a real event around the same time, and that of an event they had imagined around the same time. The Memory Characteristics Questionnaire score was higher for the memory of the near-death experience than for that of the real event, which in turn was higher than that of the imagined event. These data suggest that memories of near-death experiences are recalled as “realer” than real events or imagined events.     

The trouble with halos: Invited commentary on Kim,S., & Harris,P. L. (2014). Children prefer to learn from mind‐readers. British Journal of Developmental Psychology

This commentary on Kim and Harris (2014) addresses the authors’ interpretation of the halo effect, in which 5‐ to 6‐year‐old children preferentially agreed with an informant who could read other people's minds, regardless of domain of knowledge.     

Whose picture is this? Children's memory for item and source information

Children aged 3½ to 6½ years viewed pictures of common objects presented either once or three times on one of two consecutive days. A different hand puppet was used to present the pictures on each day, providing both perceptual and temporal cues to source. At test, old (studied) and new (non‐studied) pictures were presented for item recognition and source identification. Results showed that both item and source accuracy were higher for older (M = 5; 9 years) than younger children (M = 4; 6 years). Significant interactions between Age and Day of study were found for both item and source accuracy. For younger children, accuracy was higher for pictures studied on Day 1 than Day 2 (significant for source identification but not item recognition), whereas older children showed the opposite pattern: Higher accuracy for Day 2 than Day 1 (significant for item recognition but not source identification). Results are interpreted with respect to proactive interference and response bias. The utility of signal detection theory measures in determining the basis of age differences in performance of source identification is discussed.     

Are parenting practices associated with the development of narcissism? Findings from a longitudinal study of Mexican-origin youth

Narcissism is an important and consequential aspect of personality, yet we know little about its developmental origins. Using data from a longitudinal study of 674 Mexican-origin families, we examined cross-lagged relations between parenting behaviors (warmth, hostility, monitoring) and narcissism (superiority, exploitativeness). Parental hostility at age 12 was associated with higher levels of exploitativeness at age 14, whereas parental monitoring at age 12 was associated with lower levels of exploitativeness at age 14. These effects replicated across three different parenting measures: child reports, spouse reports, and behavioral coding of parent-child interactions. None of the parenting dimensions was related to superiority, suggesting that parenting practices are more strongly related to the maladaptive than the adaptive component of narcissism.     

Führt die evolutionäre Erkenntnistheorie in einen Relativismus?

This essay is a discussion of Eve-Marie Engels' view on Evolutionary Epistemology (EE). In the first part two of the main doctrines of EE are criticized: (1.) that validity of human knowledge is to be explained as the result of evolutionary adaptation; yet (2.), that human cognitive capacities had been adequate to our ancestors life conditions but fail in relevant situations of modern world. In the second part the concept of reality underlying EE's adaptational view is discussed and compared with Jean Piaget's concept of reality. Finally, it is held that some of the questions recently raised by proponents of EE, far from being new, have been dealt with already in historical epistemology.

Metacognition of agency and theory of mind in adults with high functioning autism

We investigated metacognition of agency in adults with high functioning autism or Asperger Syndrome (HFA/AS) using a computer task in which participants moved the mouse to get the cursor to touch the downward moving X’s and avoid the O’s. They were then asked to make judgments of performance and judgments of agency. Objective control was either undistorted, or distorted by adding turbulence (i.e., random noise) or a time Lag between the mouse and cursor movements. Participants with HFA/AS used sensorimotor cues available in the turbulence and lag conditions to a lesser extent than control participants in making their judgments of agency. Furthermore, the failure to use these internal diagnostic cues to their own agency was correlated with decrements in a theory of mind task. These findings suggest that a reduced sensitivity to veridical internal cues about the sense of agency is related to mentalizing impairments in autism.     

The two time vectors of Nachträglichkeit in the development of ego organization: Significance of the concept for the symbolization of nameless traumas and anxieties1

The author describes Freud ’s conception of Nachträglichkeit as an active process that bridges the gap between past affective vicissitudes and the cognitive present by way of meaning. Symbolization is thereby subsequently [nachträglich] conferred on early traumatic events, which thus become susceptible to omnipotent control. The two time vectors of Nachträglichkeit are discussed: the first is a causal process operating in the forward direction of time against the background of a factual reality, while the second is a backward movement that permits an understanding of unconscious scenes and phantasies taking place at primary-process level. This twofold temporal motion was observed and described by Freud early on. However, its significance often remained hidden prior to his study of Moses. It was mostly overlooked in English and French translations, thus giving rise to a one-sided understanding of the concept in the various psychoanalytic cultures, as either deferred action or après-coup. Freud ’s Moses study addresses both temporal aspects of Nachträglichkeit, seeking not only to reconstruct a past event on a causal, deterministic basis, but also to understand the subjective truth of that event in the transference along the retrograde time line. The decisive criterion for the conceptual and clinical separation of the two time vectors is the development of ego organization and the capacity for symbolization. The two vectors should not be separated on the factual level, as both aspects of Nachträglichkeit are essential to the understanding of unconscious processes, combining as they do in a relationship of circular complementarity.     

LARES: An AI-based teleassistance system for emergency home monitoring

The latest progresses in medicine are helping people live longer and better. An ageing population is a sign of a developed society with an advanced health care system. Improved life expectancy should be welcomed as a major achievement, but it should not cause a financial or social burden. In this scenario, it is critical to support older and handicap adults to continue living independently and retaining their current lifestyle. New technological advances in Wireless Sensors Networks (WSN) and Artificial Intelligence (AI) can facilitate this task.In this direction we present lares, an AI-based system that integrates a (i) WSN for receiving information of the environment and the dependent person, (ii) an autonomous robot able to take decisions based on the received information, and (iii) a Web-based system to provide telecare assistance. lares has been tried in two dependent elderly home environments during several weeks, and the experiments show that is able to detect anomalies and generate alarms in abnormal situations.
