Although ego depletion effects have been widely observed in experiments in which participants perform consecutive self-control tasks, the process of ego depletion remains poorly understood. Using the strength model of self-control, we hypothesized that chronic ego depletion adversely affects goal adherence and that mental effort and motivation are involved in the process of ego depletion. In th...

Self-affirmation is known to reduce defensive psychological responses to ego threats. The current experiment tested the hypothesis that self-affirmation reduces physiological responses to a form of ego threat-interpersonal evaluation. Participants wrote an essay and received either neutral or insulting evaluative feedback about their essay, ostensibly from another participant. Then participants...

In a review of the literature on the ego-ideal my impression has been that this concept has been placed in the position of a stepchild of the structural model of the mind, falling somewhere between the ego and the super-ego, and yet remaining loosely linked to both. Authors such as Jacobson (1954), Hartmann and Lowenstein (1962), Sandler (1963), and Schafer (196 7), have regarded the ego-ideal ...

Cognitive research on metaphoric concepts of time has focused on differences between moving Ego and moving time models, but even more basic is the contrast between Ego- and temporal-reference-point models. Dynamic models appear to be quasi-universal cross-culturally, as does the generalization that in Ego-reference-point models, FUTURE IS IN FRONT OF EGO and PAST IS IN BACK OF EGO. The Aymara l...

BACKGROUND Cell-fate determination requires that cells choose between alternative developmental pathways. For example, germ cells in the nematode worm Caenorhabditis elegans choose between mitotic and meiotic division, and between oogenesis and spermatogenesis. Germ-line mitosis depends on a somatic signal that is mediated by a Notch-type signaling pathway. The ego-1 gene was originally identif...

ego identity defined as a fundamental element of a person and as self-continuum, mental andinward image that an individual has about him or herself. this subject investigated in contemporary world, amply.for actualizing and testing this concept, four bases including achievement, moratorium, foreclosure and diffusionintroduced and based on this framework, and the effect of different factors on e...

Gene expression profiling of early eosinophil development shows increased transcript levels of proinflammatory cytokines, chemokines, transcription factors, and a novel gene, EGO (eosinophil granule ontogeny). EGO is nested within an intron of the inositol triphosphate receptor type 1 (ITPR1) gene and is conserved at the nucleotide level; however, the largest open reading frame (ORF) is 86 amin...

A study was conducted to examine the joint influence of psychosis-proneness and ego strength on creativity in college students. Psychosis-proneness and ego strength were defined psychometrically by means of Minnesota Multiphasic Personality Inventory and California Psychological Inventory profile, a procedure that resulted in creation of four categories of research subjects: (I) psychosis-prone...

Finding the global optimum(s) of a non-convex function is of great importance in numerous applications in science and engineering where the function takes the form of an expensive computer code and its inputs are the independent variables. For this type of problem, Jones et al. [12] proposed the idea of expected improvement (EI) and embedded it in an algorithm called efficient global optimizati...

AIMS The experience of a compromised sense of "self", termed ego-dissolution, is a key feature of the psychedelic experience. This study aimed to validate the Ego-Dissolution Inventory (EDI), a new 8-item self-report scale designed to measure ego-dissolution. Additionally, we aimed to investigate the specificity of the relationship between psychedelics and ego-dissolution. METHOD Sixteen item...
