Native Americans and alcohol: past, present, and future

Native Americans have higher rates of alcohol use, frequency of use, and increased rates of fetal alcohol syndrome, compared with other ethnic groups (J. Hisnanick, 1992; P. A. May, 1996; J. M. Wallace et al., 2003). High prevalence rates of alcohol misuse among Native Americans must be understood in light of their unique history, which has resulted in trauma and exposure to many risk factors for problem alcohol use. Many risk factors have been identified in the general population; however, only some of these risk factors have been examined among Native American populations. The unique history and world view of Native Americans mean that, often, risk factors operate differently from the way they do in other populations. The authors discuss interventions and promising treatments.     

Neuroprotection and stroke rehabilitation: modulation and enhancement of recovery

Recent advances in research are modifying our view of recovery after nervous system damage. New findings are changing previously held concepts and providing promising avenues for treatment of patients after stroke. This review discusses mechanisms of neuronal injury after brain ischemia and the attempts to study neuroprotection options based on such mechanisms. It also considers measures available at present to improve outcome after stroke and presents new areas of research, particularly stimulation techniques, neurogenesis and trophic factors to enhance recovery. In order to improve outcomes, medications that may be detrimental to recovery should be avoided, while symptomatic therapy of problems such as depression, pain syndromes and spasticity may contribute to better results. Continued surveillance and early treatment of complications associated with acute stroke, along with supportive care remain the mainstay of treatment for stroke patients in the recovery phase. Present research on limiting brain damage and improving recovery and plasticity enhance the prospects for better clinical treatments to improve recovery after stroke.     

Trait emotional intelligence profiles of students from different university faculties

This study investigated the trait emotional intelligence (trait EI or trait emotional self‐efficacy) profiles of 512 students from five university faculties: technical studies, natural sciences, social sciences, arts, and humanities. Using the Trait Emotional Intelligence Questionnaire, it was hypothesised that (a) social sciences would score higher than technical studies in Emotionality, (b) arts would score higher than technical studies in Emotionality, (c) arts would score lower than technical studies in Self‐control, and (d) there would be an interaction between gender and faculty, whereby female students would score higher than male students within the social sciences only. Several other exploratory comparisons were also performed. Results supported hypotheses (a), (b), and (d), but not hypothesis (c), although the differences were in the predicted direction.     

Antecedents and Consequences of Perceived Barriers to Obtaining Mentoring: A Longitudinal Investigation

Mentoring is prototypically intended to advance the personal and professional growth of new employees at work. Although meta‐analyses have found that receiving mentoring can result in beneficial outcomes for employees' career success, employees may perceive barriers to obtaining a mentor. The present research examined antecedents and consequences to perceived barriers to mentoring in business and administrative jobs in a field study over 2 years. Socioeconomic origin, positive affectivity, organizational development culture, and previous mentoring experience predicted perceived barriers to mentoring after 2 years. New employees' perceived barriers to mentoring at Time 1 predicted changes in mentoring received and income after 2 years. Implications of this study, including a proposed mentoring training program, and directions for future research are discussed.     

Mourning Religion: A Response

Mourning Religion is a brilliant collection of essays responding both to Freud’s essay “Mourning and Melancholia” and Peter Homans’ assertion that the academic study of religion represents a creative expression of mourning the loss of religion in secular (western) society. This essay poses questions concerning the role of theology as a mode of analysis; Ricoeur’s concept of “second naiveté” in relation to disillusionment and religion; Celia Brickman’s reflections on globalization, marginalization, and a shift in psychological language from “primitivity” to “vulnerability”; the role of the body in the work of religious studies; melancholia as “re-membering” amid multiplicity and fragmentation; and mourning as protest and resistance. The essay concludes with a reflection on ambiguity and transcendence in dialogue with Freud’s essay “On Transience.”     

Physical Oracles: The Turing Machine and the Wheatstone Bridge

Earlier, we have studied computations possible by physical systems and by algorithms combined with physical systems. In particular, we have analysed the idea of using an experiment as an oracle to an abstract computational device, such as the Turing machine. The theory of composite machines of this kind can be used to understand (a) a Turing machine receiving extra computational power from a physical process, or (b) an experimenter modelled as a Turing machine performing a test of a known physical theory T. Our earlier work was based upon experiments in Newtonian mechanics. Here we extend the scope of the theory of experimental oracles beyond Newtonian mechanics to electrical theory. First, we specify an experiment that measures resistance using a Wheatstone bridge and start to classify the computational power of this experimental oracle using non-uniform complexity classes. Secondly, we show that modelling an experimenter and experimental procedure algorithmically imposes a limit on our ability to measure resistance by the Wheatstone bridge. The connection between the algorithm and physical test is mediated by a protocol controlling each query, especially the physical time taken by the experimenter. In our studies we find that physical experiments have an exponential time protocol; this we formulate as a general conjecture. Our theory proposes that measurability in Physics is subject to laws which are co-lateral effects of the limits of computability and computational complexity.     

An Exploratory Study of the Relationship Between Mood States and Creativity Self-Perceptions

The purpose of this study was to investigate the relationship between noninduced mood state and self-perceptions of creativity. Undergraduate teacher education students (N = 287) completed 2 mood state inventories (Teasdale 100-Point Thermometer and Perception of Mood States) and a creative self-perception inventory (What Kind of Person Are You? [Khatena &; Torrance, 1976]). The group expressed overall indications of happiness and normally distributed creativity perceptions. Findings were mixed when the 5 scales of the creativity measure (i.e., Acceptance of Authority, Self-confidence, Inquisitiveness, Awareness of Others, and Disciplined Imagination) were correlated to the 6 dimensions of mood (i.e., Tension/Anxiety, Depression/Dejection, Anger/Hostility, Vigor/Activity, Fatigue/Inertia, and Confusion/Bewilderment). There was, however, some indication that positive mood was related to creative self-perception. Results are discussed and future research is suggested.     

Introduction: A Cognitive Science Slam in Honor of Guy Van Orden

Illusory depth perception experienced in driving simulators is afforded by monocular depth information contained in visual displays. Presumably binocular convergence and binocular disparity, though useful for depth perception in real environments, may poorly contribute to illusory depth in a driving simulator. Instead, they may generate conflicting information by revealing the distance of the display screen and its flatness. Nevertheless, illusory depth induced by monocular information contained in visual displays usually produces enough immersion and realism to create the illusion of driving in a real environment.

Many authors have noted improved depth perception in paintings, photographs, and even in drawings when viewed monocularly. However, this effect, known as monocular advantage, has never been explored in driving simulation. The purpose of this experiment was to assess whether the effect might exist in driving simulation. It was expected that drivers would perceive distances in depth better and more accurately with a monocular than with a binocular viewing of the display. Distance estimates were evaluated for two types of driving maneuvers referred to as alignment and bisection. Results showed that when significant performance differences between monocular and binocular viewing conditions occurred, target cars were perceived farther in depth and more accurately using monocular vision.

Alternative viewing conditions using both eyes are discussed at the end of the article.     

Music is What Feelings Sound Like: The Role of Tonal and Atonal Music in Unethical Behavior

Governments and societies often have condemned music as being “indecent” and encouraging people to act unethically. Despite these accusations, research did not previously address the link between music and unethical acts. Here we argue that music may signal what is appropriate or inappropriate, hence moral behavior. We focus on the distinction between tonal and atonal music to examine the relation of music with unethical behavior. Results from an experimental study showed that harmonic or tonal music encouraged unethical behavior in adolescents and this was mediated by negative affect. Our findings suggest that music plays an integral role in driving (im)moral behavior.
