Neurocognitive development in 5- to 16-year-old North American children: A cross-sectional study

Executive functions are thought to be the latest functions to mature. However, this view has not been tested by assessing simultaneously memory, perception of emotions, visuospatial perception, and visuoconstructional skills. NEPSY II norm data from 1000 5- to 16-year-old U.S. children were obtained. Fifteen NEPSY II subtests with no floor or ceiling effects in any age group and no major changes in task type were selected. The 16-year level was attained at age 12 to 13 in all subtests with two exceptions: social perception (age 10 to 11) and narrative memory (age 14). Trend analyses showed that development was rapid in the age range 5 to 9 years followed by a deceleration in the rate of development. Peak performances were reached at 14 to 16 years but later in some subtests representing executive functions, verbal memory, and visuospatial performance. Thus, the study specified developmental time tables of neurocognitive functions. It demonstrated that not only executive functions but also verbal memory and visuospatial performance continue to develop beyond age 16.     

¿Qué se percibe cuando «no se percibe»? El enmascaramiento retroactivo: una técnica equívoca para analizar la microgénesis de la percepción visual

Resumen

Con frecuencia, se ha venido recurriendo al enmascaramiento retroactivo central para estudiar la microgénesis de la percepción visual. El recurso a esta técnica venía justificado porque, al asumir que la aparición de la máscara interrumpía el procesamiento del estímulo-objetivo, permitía explorar las etapas tempranas del proceso perceptual. Sin embargo, el hecho de que ordinariamente se utilizara como criterio de percepción el informe directo de los sujetos, junto con los resultados de experimentos recientes que indican que el enmascaramiento no interrumpe el proceso perceptual en sí, sino que impide el conocimiento del estímulo percibido, obliga a una distinción entre perception y experiencia consciente de un estímulo, por una parte, y al consiguiente replanteamiento del enmascaramiento como técnica para descubrir la microgénesis perceptual, por otra. La revisión y puesta al día de estas cuestiones constituyen el contenido de este trabajo.     

The Awakening of Global Reason The Logical and Ontological Foundation of Integral Science

This article suggests that we are in the midst of a profound dimensional shift in our rational capacity to process reality, and seeks to articulate the implications of this evolutionary shift to global reason for our scientific enterprise. As we enter the 21st century it is unmistakably clear that we are in the midst of an unprecedented shift in the human condition—a global renaissance that affects every aspect of our cultural lives, our self-understanding, and, of course, our rational enterprise. This evolutionary transformation, when seen through the expanded global lens, has been emerging through the ages on a global scale. In this brief reflection I suggest that this advance in our technology of mind is of an order of magnitude that is so radical and comprehensive that the very concept of a person, of what it means to be human, of our encounter with Reality and all our hermeneutical arts, including the sciences, are likewise taken to a higher global dimension. I suggest that the diverse voices included in this special edition are best situated in the context of this global awakening of reason, scientific knowing, and the holistic worldview.     

Noogenesis—the fundamental problem of our time

The possibility of long wave economic cycles are considered under both market capitalism and command socialism. Capitalist long waves can be generated by a two‐stage multiplier‐accelerator model and socialist long waves can be generated by an equivalent model strictly for investment cycles. Under certain conditions chaotic dynamics can occur at turning points in both cases. It is argued that a systemic crisis leading to a systemic transformation is most likely to occur at such a point.     

Rediscovering Meaning

The present crisis of the Western countries involves not just the world of politics, finance, and the economy, but also the ecosystem balance, the world of the values on which the model of social organization and economic development is based. The crisis is therefore systemic, epoch-making, and overcoming it will require radical changes, above all in the way we think, in our scale of values, and therefore our culture. On the other hand, for decades the world—in particular the West—has been experiencing a cultural sea-change that is challenging many of the pillars of society that have stood for centuries. The young people of today and their use of technological social networks to develop non-profit initiatives for social change may create a more positive future while maintaining our human values.     

Perceptual Integration of Timing and Intensity Variations in the Perception of Musical Accents

The author investigated the detection of timing and intensity variations in tone sequences within the framework of perceptual independence or integration. The participants listened to sequences of tones that contained variations in timing, intensity, or both. Each participant tried to detect variations in the dimension that was declared relevant, which was either timing or intensity. The irrelevant dimension was held constant, or varied in a manner uncorrelated with the relevant dimension, or varied in a correlated manner. When the variations in the 2 dimensions were correlated, the correlation could be either positive (i.e., timing and intensity created accents in the same sequences) or negative (i.e., timing and intensity created accents in different sequences). Uncorrelated variation in the irrelevant dimension interfered with the detection of variations in the relevant dimension. In the case of a positive correlation between the 2 dimensions, the detection of variations was better than it was with the absence of variation in the irrelevant dimension only for participants who attended to timing. In the case of a negative correlation, the effect was the opposite. The results showed that timing and intensity accents were not processed by completely independent channels. Rather, information from the 2 dimensions combined at a late stage of processing.     

Can We Consume Our Way Out of Climate Change? A Call for Analysis

The problem of climate change is analyzed as a manifestation of economic growth, and the steady-state economy of ecological economics is proposed as a system-wide solution. Four classes of more specific solutions are described. In the absence of analysis, cultural inertia will bias solutions in favor of green consumption as a generalized solution strategy. By itself, green consumption is a flawed solution to climate change because it perpetuates or even accelerates economic growth that is incompatible with a sustainable culture. Addressing climate change requires an integration of regulatory, energy efficiency, skill-based, and dissemination solutions. Behavioral scientists are encouraged to work with others in ecological economics and other social sciences who recognize cultural reinvention as a means of achieving sustainability.
