Psychological and autonomic effects of art making in college-aged students

Background and objectives: Anxiety disorders comprise the most common category of mental illness among US young adults. Art making might be one method to help reduce anxiety, but the few studies investigating this have used only subjective measures of anxiety. Design: This study employed both subjective (self-reported state anxiety from the State-Trait Anxiety Inventory) and objective (heart rate variability) measures to assess whether 30-minute periods of art making reduced anxiety in 47 first-year college students prior to their final examinations. Methods: Students participated in free-form painting, mandala coloring, clay modeling, and control sessions. Results: Repeated-measures ANOVA with post hoc analysis revealed significantly greater pre- to post-session reductions in anxiety for all three types of art-making sessions than for the control session, as measured objectively. Measured subjectively, only free-form painting yielded a significant decrease in anxiety compared to the control session. Conclusions: Given the health benefits of anxiety reduction, further study is warranted to determine the duration of art making's anxiety-reducing effect.     

Mixing Bodily Fluids: Hobbes’s Stoic God

The pantheon of seventeenth-century European philosophy includes some remarkably heterodox deities, perhaps most famously Spinoza’s deus-sive-natura. As in ethics and natural philosophy, early modern philosophical theology drew inspiration from classical sources outside the mainstream of Christianized Aristotelianism, such as the highly immanentist, naturalistic theology of Greek and Roman Stoicism. While the Stoic background to Spinoza’s pantheist God has been more thoroughly explored, I maintain that Hobbes’s corporeal God is the true modern heir to the Stoic theology. The Stoic and Hobbesian gods are necessitarian, entirely corporeal, and thoroughly intermixed with ordinary bodies, while also supremely intelligent, providential, and good. And both gods serve as the ultimate source of diversity and change in a material world divested of Aristotelian forms and causes. Unfortunately, scholars on both sides of the long debate about the sincerity of Hobbes’s theism have not taken very seriously his late articulation of a corporeal theology. One probable reason for this dismissive attitude is a lack of thorough investigation of the historical precedents for such an unusual godhead available to Hobbes. The first part of this article attempts to establish a close congruence between the Stoic and Hobbesian gods. The second part traces the likely sources for Hobbes’s Stoic theology in his intellectual context.     

Universal Popular Responses to Inkblots in Five Cultures: Denmark,Germany, Hong Kong,Mexico and United States

Klopfer and Kelly in 1942 predicted that “a sufficient number of frequency counts” would indicate universality of response to certain inkblots by groups, e.g. cultural. Group administration and the development of a computer based scoring program has enabled the authors to examine adequate frequencies across five cultures (Denmark, Germany, Hong Kong, Mexico, United States) and validate the prediction. Using Holtzman's criterion for Popular, universality was found in 23 inkblots and near-universality in 10 additional. The core concept person accounted for the populars in 15 instances; other concepts were animal, fowl, face or mask, person-riding-animal, landscape, butterfly or moth, seahorse, fish, and rain or storm. Across all five cultures there was much more commonality than differences in perception of inkblots.     

A study of the restitution coefficient in elastic-plastic impact

The aim of this work is to provide useful quantitative support for theories of the restitution coefficient for normal impacts involving plastic deformation, especially in the region close to the threshold at which plastic deformation begins. The impacts were from spheres of 5 mm diameter of aluminium oxide (which deformed elastically), dropped on to thick plates of mild steel or aluminium alloy. Very accurate measurements of impact and rebound velocities were made for drop heights from 1.75 m down to 0.6 mm, covering a range of velocities down to the yield threshold. Most of these results are in the elastic-plastic velocity range over which the indentation pressure varies from its value at initial yield of about 1.1sigma_y to the value when full plasticity is established of about 2.8sigma_y. The variation in the restitution coefficient with velocity in this range closely fits the rebound model of Tabor, which allows the indentation pressure to vary through the Meyer index n. The fitted values of n take into account these elastic-plastic effects as well as work hardening, demonstrating that a power-law compliance relationship is a very good model for the increase in indentation pressure as plasticity develops. Full plasticity only becomes established at impact velocities which are of the order of 100 times the velocity at which initial yield takes place. Models which assume a constant indentation pressure (perfect plasticity) are not a good match for the data in the elastic-plastic regime.     

The Theological Foundation of Hobbesian Physics: A Defence of Corporeal God

In 1668, the octogenarian Hobbes finally affirmed openly a doctrine that was unavoidable given his longstanding embrace of both theism and materialism: God is corporeal. However, this doctrine has generally been downplayed or dismissed by scholars, who have alleged that Hobbes's corporeal theism is irreconcilable with his more orthodox theological pronouncements or with his fundamental metaphysical principles. This paper defends the coherence of Hobbes's corporeal God against particularly vigorous criticisms of Douglas Jesseph and others. The aim of the paper is not, however, to situate Hobbes's deity safely within the boundaries of seventeenth century protestant theology, as defenders of Hobbesian theism have often wanted to do. Rather, the paper places the corporeal God at the metaphysical foundations of Hobbes's natural philosophy. Despite his early reticence about theological speculation, Hobbes eventually relied on God to provide a continuous, resistance-free source of motion or conatus to a material plenum whose parts would otherwise quickly slow to an infinitesimal crawl. Hobbes's late theology, while certainly heterodox in content, is not so different in function from that of contemporaries like René Descartes and Henry More, whose religious sincerity is rarely questioned. Hobbes' corporeal deity deserves a place in the seventeenth century pantheon.     

Autonomic learning

Academic achievement was resolved into its intellectual and motivational components. IQ, personality variables, and parameters of operant and classical conditioning of autonomic nervous system controlled variables were examined in 99 black inner-city high school seniors. Six physiological variables(respiration, heart rate, finger plethysmogram, frontalis muscle potential, palmar skin conductance, and palmar skin potential) were analyzed by computer using analog-to-digital conversion and a Points of Interest (PI) program. Psychological measures were full WAIS IQ, Edwards Personality Inventory(EPI), Cattell Sixteen Personality Factor Questionnaire(16PF), McClelland need Achievement test(n Ach), Object Sorting test, Minnesota Counseling Inventory(MCI), Level of Aspiration Board, and Rotter—Miller Locus of Control. Achievement(Ach) was defined as the residuals of total grade point average(GPA) regressed on IQ. Each of 19 variables which discriminated significantly between high and low achievers was employed in step-wise regression analyses for GPA and Ach separately. In a regression analysis of variance of GPA, IQ=20.44%, EPI=9.08%, and physiological measures =21.37%(operant conditioning =18.70%; classical conditioning =2.67%). Combined measures of motivation(psychological and physiological) =30.45% of the variance in GPA. The entire psychological and physiological test battery, including IQ, contributed a total of 50.89% of the variance in GPA. In a regression analysis of variance in achievement, psychological measures, other than IQ(six EPI and one 16PF), =11.0% and physiological measures =30.3%. As a replication, this study demonstrated significant correlation between autonomic conditioning and school achievement.

What Produces Television Attention and Attention Style?

Individual looks at television vary enormously in length, and this has previously indicated differences in ongoing cognitive processes. Furthermore, the relative frequency of looks of different lengths may indicate styles of attention to television. This article compares visual attention of 152 subjects across a variety of genres and examines differences located by situation, person, and media perception variables. Attention style was not consistent for individuals but varied for different types of programming and between‐program breaks. Situational, person, and media belief variables did not predict the proportions of four types of looks. They did, however, predict differences in the proportion of moderately short (orienting) looks across types of content, but not the previously more important very short (monitoring) or moderately long (engaged) looks. The overall importance of type of content in these results suggests that further research should examine within‐program differences in message construction and assess attentional style as patterns or sequences of looks.
