Augmenting Visual Search Performance With Transcranial Direct Current Stimulation (tDCS)

Military personnel endure rigorous and demanding man-hours designated to monitoring and locating targets in tasks such as cyber defense and Unmanned Aerial Vehicle (UAV) operators. These tasks are monotonous and repetitive, which can result in vigilance decrement. The objective of the study was to implement a form of noninvasive brain stimulation known as transcranial DC stimulation (tDCS) over the left frontal eye field (LFEF) region of the scalp to improve cognitive performance. The participants received anodal and cathodal stimulation of 2 mA for 30 min as well as placebo stimulation on 3 separate days while performing the task. The findings suggest that anodal and cathodal stimulation significantly improves detection accuracy. Also, a correlation was detected between percent of eye closure (PERCLOS) and blinking frequency in relation to stimulation condition. Our data suggest that tDCS over the LFEF would be a beneficial countermeasure to mitigate the vigilance decrement and improve visual search performance.     

Parents Support Preschoolers' Use of a Novel Interactive Device

Past research has found that preschool children's ability to learn educational content from interactive media may be hindered by needing to learn how to use a new interactive device. However, little research has examined the instructional supports parents provide while their children use interactive media. Forty‐six preschool children and their parents participated in a 30‐min interaction with a novel interactive device. Children were assessed before and after the interaction on knowledge of letters and numbers and device skills. Children improved from pre‐ to posttest on device skills, but not content knowledge. In general, parents used a wide range of strategies during the interaction. Specific parental support for using the device did not result in increased device skills; however, parents who focused their support on content had children who performed better on content assessments. The findings are discussed in terms of the effectiveness of different parent support strategies for children's use of interactive devices and learning of educational content during the preschool years.

Hemispheric predominance assessment of phonology and semantics: a divided visual field experiment

The aim of the present behavioural experiment was to evaluate the most lateralized among two phonological (phoneme vs. rhyme detection) and the most lateralized among two semantic ("living" vs. "edible" categorization) tasks, within the dominant hemisphere for language. The reason of addressing this question was a practical one: to evaluate the degree of the hemispheric lateralization for several language tasks, by using the divided visual presentation of stimuli, and then choose the most lateralized semantic and phonological for mapping language in patients by using fMRI in future studies. During the divided visual field experiment by using words (semantic tasks) and pseudo-words (phonological tasks) as stimuli, thirty-nine right-handed participants were examined. Our results have shown that all tasks were significantly left hemisphere lateralized. Furthermore, the rhyme was significantly more lateralized than phoneme detection and "living" was significantly more lateralized than "edible" categorization. The rhyme decision and "living" categorization will be used in future fMRI studies for assessing hemispheric predominance and cerebral substrate for semantics and phonology in patients. Our results also suggest that the characteristics of stimuli could influence the degree of the hemispheric lateralization (i.e., the emotional charge of stimuli for words and the position of the phoneme to be detected, for pseudo-words).     

Visual-Field Bias in the Judgment of Facial Expression of Emotion

The left and right hemispheres of the brain are differentially related to the processing of emotions. Although there is little doubt that the right hemisphere is relatively superior for processing negative emotions, controversy exists over the hemispheric role in the processing of positive emotions. Eighty right-handed normal male participants were examined for visual-field (left-right) differences in the perception of facial expressions of emotion. Facial composite (RR, LL) and hemifacial (R, L) sets depicting emotion expressions of happiness and sadness were prepared. Pairs of such photographs were presented bilaterally for 150 ms, and participants were asked to select the photographs that looked more expressive. A left visual-field superiority (a right-hemisphere function) was found for sad facial emotion. A hemispheric advantage in the perception of happy expression was not found.     

Chaotic attractors in the therapeutic system 1

Because little research had been done on the presence and role of latent communication in the context of team‐conducted family therapy, the writers set out to monitor unconscious responses generated under these conditions. Specifically, they investigated an ongoing family treatment situation conducted according to the “reflecting team model.” One team of therapists handles the actual treatment session, while the other observes from behind a one‐way mirror. During the course of a session, the second team makes suggestions to the treatment team either by telephone or by calling the therapists out of the treatment room.

As the project developed, the writers found that the unconscious responses of both family and treatment teams indicated a process at work beyond the conscious intentions of the participants. That is, the therapeutic enterprise was functioning as a dynamical system, whose increasing complexity suggested a self organizing principle at work. This paper traces the development of the system's movement toward greater complexity, identifies the specific interventions that indicate this process, describes how all participants demonstrated a high degree of resonance and synchronization with this overarching‐self organizing pattern. This paper serves to alert therapists to the role of unconscious communication within the therapeutic system and postulates that the generation of form within psychotherapy follows many of the same self organizing processes found in other human and non human systems.     

The New Sacred Math

The individual soul is an ageless idea, attested in prehistoric times by the oral traditions of all cultures. But as far as we know, it enters history in ancient Egypt. I will begin with the individual soul in ancient Egypt, then recount the birth of the world soul in the Pythagorean community of ancient Greece, and trace it through the Western Esoteric Tradition until its demise in Kepler's writings, along with the rise of modern science, around 1600 CE. Then I tell of the rebirth of the world soul recently, in new branches of mathematics.     

All of The Myriad Worlds: Life in the Akashic Plenum

This article explores some experiential implications of Laszlo's Akashic Field hypothesis as well as similar information-rich field models such as those suggested by Bohm and Sheldrake. It examines the implications of such models for both ordinary and anomalous human experience, and proposes the idea that these models allow for the possibility of alternative experiential worlds as real as ordinary “material” reality. Such alternative realities are posited by many, if not all, major mythic and religious systems, and are said to be directly experienced in certain contemplative and shamanic traditions as well as during postmortem and near-death experiences. We note that information-rich holographic fields may be able to store concentrated non-overlapping quantities of information that can be selectively activated by distinct eliciting stimuli. Individual human consciousness itself might constitute just such a stimulus, thus accounting for the individual and cultural variations on commonly shared motifs in shamanic, near death, and other experiences of alternative realities.     

The Whole is Greater: Reflective Practice,Human Development and Fields of Consciousness and Collaborative Creativity

Because Western experiments assume creativity is an individual phenomenon and rarely investigate how trust and openness might build collective resonance, flow, and creativity, the creative whole typically amounts to less than the sum of the parts. The author argues, however, that group creativity increases as members develop, especially through Wilber's (in press) transpersonal stages. He illustrates how organizational leaders have facilitated creativity through reflective practice. Presenting evidence regarding the field effects of collective consciousness, he suggests that our minds and hearts interact in subtle yet powerful ways, which leaders can intuit, to support the emergence of collaborative creativity.     

Philosophy as a kind of courage

It is possible to reveal and to examine the collective and social fields of consciousness experimentally. An account is given of planned experiments based on quantitative calculations, which indicate that the effects of individual and collective fields of consciousness on matter may elicit directly observable physical results. Moreover, it is shown that collective coherent consciousness fields may enhance the physical effects of consciousness at a significant rate. The predicted results have a significance in our picture of our consciousness, in self‐assertion and dynamising of consciousness, the expansion of collective fields of consciousness, and thus the raising of the level of consciousness for humanity.
