The Promotion of New Behavior by Forming an Implementation Intention: Results of a Field Experiment in the Domain of Travel Mode Choice1

In the context of an experimental field study, it is analyzed whether furnishing a goal intention with an implementation intention (Gollwitzer, 1993) increases the probability that a new behavior is enacted. For this purpose, 90 students who did not normally use public transportation were asked to test (just one time) a special public transportation offer they had never used before. With a nonobstrusive questionnaire manipulation, the subjects of the experimental group were stimulated to form an implementation intention. The results show that forming an implementation intention significantly increases the probability of enacting the goal intention; that is, testing the public transportation offer. The theoretical and practical implications of this finding are discussed.     

‘For Beauty is nothing but the barely endurable onset of Terror’: Outline of a general psychoanalytic aesthetics

Even close to 80 years after Freud's words that psychoanalysis “has scarcely anything to say about beauty” (Freud, Civilization and its Discontents, SE 21, p. 82) the question of a specific psychoanalytic aesthetic is still faced with a deficit in theory. Since aesthetics is related to Aisthesis, the Greek word for ‘perception’, a psychoanalytic aesthetic can solely emerge from a psychoanalysis of perceptive structures. The term ‘kinaesthetic semantic’ is introduced in order to exemplify via music how perceptive experiences must be structured for them to be experienced as beautiful. The basic mechanisms – repetition of form (rhythm, unification) and seduction (deviation, surprise) – are defined. With the help of these mechanisms an intensive contact between perceiving object and kinetic subject, the physical self, is established. The intensive relatedness is a requirement for the creative process in art and also for psychic growth on the subject's level. The described basic mechanisms of the aesthetic process in music can also be encountered in painting and poetry. By the means of a self‐portrait by Bacon it will be examined how, in art, terror and traumatization are represented via targeted disorganization of beauty endowing mechanisms, hence finding an enabling form of confrontation and integration of fended contents.     

Age-Related Differences in Locomotor Strategies During Adaptive Walking

Simultaneous control of lower limb stepping movements and trunk motion is important for skilled walking; adapting gait to environmental constraints requires frequent alternations in stepping and trunk motion. These alterations provide a window into the locomotor strategies adopted by the walker. The authors examined gait strategies in young and healthy older adults when manipulating step width. Anteroposterior (AP) and mediolateral (ML) smoothness (quantified by harmonic ratios) and stepping consistency (quantified by gait variability) were analyzed during narrow and wide walking while controlling cadence to preferred pace. Results indicated older adults preserved ML smoothness at the expense of AP smoothness, shortened their steps, and exhibited reduced stepping consistency. The authors conclude that older adults prioritized ML control over forward progression during adaptive walking challenges.     

The interplay of intention maintenance and cue monitoring in younger and older adults’ prospective memory

The retention phase of a prospective memory (PM) task poses different challenges, including demands to store or maintain an intended action and to realize the right moment for action execution. The interplay of these processes in younger and older adults has not been explored so far. In this study, the authors examined the impact of maintenance load and task focality on PM in 84 younger and in 83 older adults. Results indicated that PM performance and ongoing task response times were strongly affected by maintenance load and age. However, a focality effect only emerged when maintenance load was low but not when attentional resources were deployed for maintaining a more demanding intention. These findings suggest that maintenance and monitoring requirements compete for similar attentional resources. Furthermore, maintenance load may affect postretrieval processes through its impact on working-memory resources, which can restrain the typical advantage of focal over nonfocal PM tasks.     

Reply to Dews,and a plea for Schelling

The discussion is a response to Dews on the question of how Schelling's Freiheitsschrift should be interpreted. It falls into two halves, the first defending my interpretation, and the second expanding on the case that Dews makes for the unavoidability of metaphysics in the theory of human freedom, with which I am in full agreement. The main criticism that Dews makes of my reading is that the argument I attribute to Schelling concerning the metaphysical significance of evil rests on Kantian assumptions regarding the existence of pure practical reason, which Schelling rejects. I argue that, though certainly matters are more complicated than my earlier discussion made them seem, Schelling remains sufficiently close to Kant for the argument I attribute to avoid inconsistency. In the second half I raise what I claim to be a neglected but important question: Why is the legacy of classical German philosophy not regarded as significant for contemporary discussion of human freedom? My answer in brief is that the concept of freedom has undergone a profound contraction. In this context I also try to define more precisely what is distinctive of Schelling's view of human freedom.     

Multifractality Versus (Mono-) Fractality as Evidence of Nonlinear Interactions Across Timescales: Disentangling the Belief in Nonlinearity From the Diagnosis of Nonlinearity in Empirical Data

This article addresses the still popular but incorrect idea that monofractal (sometimes called “fractal” for short) structure might be a definitive signature of nonlinearity and, as a corollary, that monofractal analyses are nonlinear analyses. That this point (i.e., “fractal = nonlinear”) is incorrect remains novel to many readers. We suspect that unfamiliarity with autocorrelation has helped eclipse the linearity of fractal structure from more popular appreciation. In this article, in order to explain the linear nature of monofractality and its difference from multifractality, we present an introduction to the autocorrelation function and review short-lag memory, nonstationary motions, and the intermediary set of fractionally integrated processes that conventional fractal analyses quantify. Understanding from our own experiences how surprising the linearity of fractals is to accept, we attempt to make our points clear with as much graphic depiction as math. We hope to share our own experiences in struggling with this potentially strange-sounding idea that, really, monofractals are linear while at the same time contrasting them to multifractals that can indicate nonlinearity.
