Practice Effects in Bimanual Force Control: Does Age Matter?

ABSTRACT

The authors examined age-related differences in fine motor control during a bimanual coordination task. The task required the modulation of fingertip forces in the precision grip according to a visually presented sinusoidal antiphase pattern (force range 2–12 N; frequency 0.2 Hz). Thirty-four right-handed participants of three age groups (young, early middle-aged, and late middle-aged) practiced 30 trials of the task. Accuracy and variability of relative timing and relative forces at minima and maxima of the sine wave were analyzed for hand–hand and hand–stimulus couplings and compared between age groups. Analysis showed for relative timing and force weaker hand–hand than hand–stimulus coupling as well as lower accuracy and higher variability for minima as compared to maxima. Further, we analyzed practice effects by comparing the first and last trials and characterized the course of practice by detecting the transition of a steeper to a shallower acquisition slope for the different age groups. Late middle-aged participants demonstrated poorer performance than both other groups for all parameters. All groups improved performance to a similar amount. However, an age-related difference in acquisition strategy is visible. Late middle-aged participants seemed to have focused on improvement of force amplitude, whereas young and early middle-aged focused on timing.     

Focusing and Expressive Arts Therapy as a Complementary Treatment for Women with Breast Cancer

Abstract

This pilot study (N = 18) explored the effectiveness of focusing and expressive arts therapies intervention on the quality of life of women with breast cancer. The format was a 2-day (7 hours per day) retreat/support group in which complementary treatments (focusing, writing, art, and movement) were provided in an intensive format. Our hypothesis was that an integrated approach of multimodal expressive arts therapy would result in improvements in several measures of the participants' qualities of life. There was a 6-week post-group follow-up telephone interview, during which several participants reported positive results. This suggests that the intervention was beneficial.     

Psychoanalysis as a creative shaping process2

The author first explains the concepts of creativity, play and aesthetic experience. He then outlines the psychoanalytic process as a creative one that shapes reality. Making a link between psychoanalysis and the humanities, he demonstrates that creative play is a fundamental aspect of the human experience of reality. Aesthetic experiences during the psychoanalytic process are comparable to the play by which children structure their world and artists' activity in following their urge to shape. Furthermore it is shown that creative actualisation testifies to a quasi‐biological need for coherence and structure. Through modern hermeneutics, the truth claims of aesthetic shaping can be established in epistemological terms. The basic principles of hermeneutics‐historicity, linguisticity and communicative experience‐find their psychoanalytic counterparts in memory, representational shaping and transference‐countertransference. Psychoanalysis is demonstrated to be simultaneously a science and an art. On the basis of a case history, aesthetic experience is shown to constitute a specific and unique form of access to psychic reality. Aesthetic experience and creativity do not only aid recovery from ‘bad psychological states’, they are also indispensable for the entire understanding of internal and external reality. It is possible to develop this understanding through a creative psychoanalytic attitude.     

Dreaming woman: Image,place, and the aesthetics of exile

Looking closely at an Argentine dream interpretation column published in a popular women's magazine from 1948 to 1951, this article examines the role of the dream image in shaping psychoanalytic discourse on femininity and national identity. The column, ‘Psychoanalysis Will Help You,’ emerged during Juan Domingo Perón's first presidency, featuring verbal interpretations written under the pen name ‘Richard Rest,’ as well as surreal photomontages by Grete Stern, a German‐born, Bauhaus‐trained photographer living in exile since 1936. While the column's Jungian text encourages readers’ adaptation to the external reality of their social situation, Stern's droll images emphasize the disjuncture between subject and environment, exposing tensions between the experience of exile and the Peronist mission to consolidate an Argentine national identity. Experimenting formally with European avant‐garde techniques, Stern presents femininity and nation as conflictive imaginary configurations. This theme resurfaces at the 2013 Venice Biennale, where Nicola Costantino's multimedia installation Eva – Argentina: A Contemporary Metaphor was exhibited alongside Carl Jung's Red Book. Formal contrasts between Stern's use of photomontage, Costantino's projection technique, and Jung's theory of mandala symbolism indicate the divergent ways in which their artwork posits the therapeutic function of the dream image, as well as the role of aesthetic production in psychoanalytic care.     

A Return to Musical Idealism

In disputes about the ontology of music, musical idealism—that is, the view that musical compositions are ideas—has proven to be rather unpopular. We argue that, once we have a better grip on the ontology of ideas, we can formulate a version of musical idealism that is not only defensible, but plausible and attractive. We conclude that compositions are a particular kind of idea: they are completed ideas for musical manifestation.     

Prevalence and correlates of tattooing in Norway: A large‐scale cross‐sectional study

To our knowledge, no previous large‐scale study has examined the prevalences and correlates of having only easily concealed tattoos, or readily visible tattoos. We conducted an exploratory online survey in Norway asking 15,654 (6,151 females) persons aged 16–91 (m = 33.65 ± 12.27) about various demographic, sports, substance use, mental health, personality, and tattooing questions. The estimated prevalence of tattooing was 20.8% (females: 23.8%, males: 17.9%), of which 13.3% had readily visible tattoos. Results of multivariate logistic regression analysis indicated that females, being older than 19 years, higher body mass index, lifetime anabolic‐androgenic steroid use (AAS), and higher scores on extraversion were associated with higher odds of having a tattoo. Factors associated with higher odds of having only easily concealed tattoos were being 40–49 (versus those ≤ 19) years old, being only high school or tertiary (versus being only primary school) educated, often or not (versus always) exercising in a gymnasium, and high scores on agreeableness. Females, and higher scores on extraversion and neuroticism were associated with higher odds of having at least one readily visible tattoo. Our findings delineate the significance of demographic variables, gymnasium exercise, AAS, and personality in the practice of tattooing.     

Defining the sacred in fine art and devotional imagery

ABSTRACT

Beginning with a definition of the sacred as a two-fold process of making things special, which consists of accentuation and affiliation, this essay proceeds to argue that things are made sacred in devotional piety and in fine art in parallel ways that configure images within webs of agents. The two kinds of imagery perform in practices of sacralization that move toward different ends. The production of aura is at work in each case, but operates with distinct aims. The essay then presents a historical account of fine art as a modern development tied to the rise of the nation-state, in which secularization extended to making art independent of religious institutions and patrons, allowing it to develop in a way that should be distinguished from devotional imagery. This does not mean that religion withers in the modern era, but that art developed its own mode of sacralization.     

An Aesthetic Review of New Mothers as the Ultimate Weaver: Achieving a Harmonious Integration of Prevalent Discourses and Lived Experience

Experiences in new motherhood are influenced by popular sociological discourses and ideologies. The narratives promoted in these discourses may or may not fit with the subjective experience of the mother. Lacking experience in motherhood, the new mother may misguidedly accept these mainstream discourses and ideologies as standard. The process of adapting and blending sociological narratives to fit with lived experience is similar to the art of weaving. This article, an original argument grounded in relevant literature, explores how new mothers can develop a balanced weave of popular social discourse and her subjective experience by: accepting motherhood as a creative process, being aware of the powerful influence of social constructs on her perceptions, and recognizing the influence of her body/biology on her lived experience. The aesthetic narrative of the spider, the ultimate weaver, accompanies the research presented. Complementary art therapy interventions such as weaving, art boxes, and dolls are discussed.
