Tina Keller's analyses with C. G. Jung and Toni Wolff, 1915-1928

This historical essay documents the clinical practices of C. G. Jung and Toni Wolff with their analysand Tina Keller, a Swiss physician and psychotherapist, during the formative years of analytical psychology (1915-1928). The topic is investigated through an examination of primary documents, largely unpublished, in English and German, based on Keller's autobiographical writings. It presents biographical information on Keller's life and details of her analyses with Jung and Wolff, emphasizing the technique of active imagination and describing the clinical practices of Jung and Wolff in Keller's analyses.     

"是-应该"问题及其解答

休谟提出如何从“是”推出“应该”,亦即如何从事实判断推出价值判断的问题。本文以该问题为线索,评述和澄清休谟道德哲学的主要观点,并对与此问题密切相关的“囚徒困境”作了探讨。在此基础上,提出一种新的解答,即：“是一应该”问题是不能彻底解决的,在这个意义上,休谟的“是一应该”论题是正确的。但是,在另一种意义上,“是一应该”问题是可以解决的,即对于那些已经把长远利益作为追求目标的人而言是如此。因为对他们来说,追求长远利益已经是一个事实,因而必须考虑与他人或社会的合作,这使他们原有的同情心得到加强,从而产生名誉感和自尊心,进而达到正义和仁慈的德行。这样便从追求长远利益的“是”得出正义和仁慈的“应该”。     

The neuronal basis of bimanual coordination: recent neurophysiological evidence and functional models

Recent physiological studies of the neuronal processes underlying bimanual movements provide new tests for earlier functional models of bimanual coordination. The recently acquired data address three conceptual areas: the generalized motor program (GMP), intermanual crosstalk and dynamic systems models. To varying degrees, each of these concepts has aspects that can be reconciled with experimental evidence. The idea of a GMP is supported by the demonstration of abstract neuronal motor codes, e.g. bimanual-specific activity in motor cortex. The crosstalk model is consistent with the facts that hand-specific coding also exists and that interactions occur between the motor commands for each arm. Uncrossed efferent projections may underlie crosstalk on an executional level. Dynamic interhemispheric interactions through the corpus callosum may provide a high-level link at the parametric programming level, allowing flexible coupling and de-coupling. Flexible neuronal interactions could also underlie adaptive large-scale systems dynamics that can be formalized within the dynamic systems theory approach.

The correspondence of identified neuronal processes with functions of abstract models encourages the development of realistic computational models that can predict bimanual behavior on the basis of neuronal activity.     

The interplay of attention and bimanual coordination dynamics

Despite their common origin, studies on motor coordination and on attentional load have developed into separate fields of investigation, bringing out findings, methods, and theories which are diverse if not mutually exclusive. Sitting at the intersection of these two fields, this article addresses the issue of behavioral flexibility by investigating how intention modifies the stability of existing patterns of coordination between moving limbs. It addresses the issue, largely ignored until now, of the attentional cost incurred by the central nervous system (CNS) in maintaining a coordination pattern at a given level of stability, in particular under different attentional priority requirements. The experimental paradigm adopted in these studies provides an original mix of a classical measure of attentional load, namely, reaction time, and of a dynamic approach to coordination, most suitable for characterizing the dynamic properties of coordinated behavior and behavioral change. Findings showed that central cost and pattern stability covary, suggesting that bimanual coordination and the attentional activity of the CNS involved in maintaining such a coordination bear on the same underlying dynamics. Such a conclusion provides a strong support to a unified approach to coordination encompassing a conceptualization in terms of information processing and another, more recent framework rooted in self-organization theories and dynamical systems models     

Depotentiation of vdccLTP Requires NMDAR Activation

Long-term potentiation is an enduring increase in synaptic efficacy following repeated stimulation of afferent fibers that is thought to underlie memory. In area CA1 of the hippocampus at least two forms of synaptic potentiation coexist at the same synapses; nmdaLTP and vdccLTP. NmdaLTP is induced by Ca2+ entry through NMDARs and is dependent on serine/threonine kinase activation, while vdccLTP is induced through Ca2+ entry through VDCCs and is dependent on tyrosine kinase activation. Depotentiation is a mechanism known to reverse nmdaLTP through phosphatase activation. The depotentiation of vdccLTP has not been previously investigated. We used hippocampal slices (area CA1) from male Long-Evans rats to induce vdccLTP with a 200-Hz tetanus in the presence of 50 microM APV. The 200-Hz tetanus resulted in a slowly developing vdccLTP that remained stable for at least 30 min. Thirty minutes after vdccLTP was induced, a low-frequency tetanus (3, 10, 20, 30, or 40 Hz) was applied in the presence of APV in an attempt to depotentiate vdccLTP. The 3- and 10-Hz low-frequency tetani resulted in no depotentiation. The 20- and 30-Hz tetani partially depotentiated vdccLTP (by approximately 13%), whereas the 40-Hz tetanus resulted in further potentiation. When APV was washed out prior to the 3-Hz low-frequency tetanus, the vdccLTP was completely depotentiated--presumably by NMDAR mechanisms. Our results indicate that vdccLTP is resistant to depotentiation under low-frequency stimulation conditions that readily depotentiate nmdaLTP. As tetanus frequencies are increased a small depotentiation is observed, suggesting that vdccLTP can be depotentiated to a small extent. When NMDARs are unblocked, vdccLTP can be completely depotentiated by a 3-Hz low-frequency tetanus, suggesting that vdccLTP can be depotentiated via activation of NMDAR mechanisms.     

Looking is not enough: Multimodal attention supports the real-time learning of new words

Most research on early language learning focuses on the objects that infants see and the words they hear in their daily lives, although growing evidence suggests that motor development is also closely tied to language development. To study the real-time behaviors required for learning new words during free-flowing toy play, we measured infants’ visual attention and manual actions on to-be-learned toys. Parents and 12-to-26-month-old infants wore wireless head-mounted eye trackers, allowing them to move freely around a home-like lab environment. After the play session, infants were tested on their knowledge of object-label mappings. We found that how often parents named objects during play did not predict learning, but instead, it was infants’ attention during and around a labeling utterance that predicted whether an object-label mapping was learned. More specifically, we found that infant visual attention alone did not predict word learning. Instead, coordinated, multimodal attention–when infants’ hands and eyes were attending to the same object–predicted word learning. Our results implicate a causal pathway through which infants’ bodily actions play a critical role in early word learning.     

Interpersonal coordination tendencies and perception of visual information for decision-making in futsal

This study investigated how futsal players visually perceived information on angular interpersonal coordination relations, between available sources such as nearest defender, goalkeeper position and ball, when deciding to shoot at goal. Experienced players (n = 180) participated in eighteen, video-recorded futsal matches, during which 32 participants wore an eye tracking device. Forty-five sequences of play were selected and edited from the moment a teammate passed the ball to the shooter, until the moment a shot was undertaken. Independent variables included the angle connecting the shooter to their closest defender and goalkeeper, and it’s rate of change (velocity and variability) during performance. Then eye tracking system (TOBII PRO) was used to examine gaze patterns of shooters during task performance. Findings revealed that: (i) futsal players adapted their gaze patterns differently between key information sources when shooting confirmed as: their closest defender, goalkeeper, ball, and court floor; and (ii), the ball was the information source which was most fixated on, regardless of the characteristics of interpersonal coordination tendencies that emerged when shooting. These findings can be interpreted as evidence of functional perceptual behaviours used to regulate actions needed to ensure precise contact with the ball when shooting at goal. Further, adaptations of fixation patterns, varied between marking defender, goalkeeper, and ball, may provide functional postural orientation to facilitate a successful shot at goal.

The I Ching as a Potential Jungian Application: History and Practice

Swiss psychiatrist Carl Jung had a lifelong interest in the I Ching after discovering it in 1919. Jung’s interest in the I Ching is arguably more practical than purely theoretical or intellectual, and references to I Ching divination appear frequently in his various publications, seminars, letters and clinical practice records. After a few observations on the history of the study of the I Ching in China, the author categorizes Jung’s three uses of the I Ching as physical use (to preview future potentials of outer reality), psychological use (to reveal one’s psychological state), and psychical approach (to engage with the divine through “神”[“shen”, spiritual agencies]). Finally, the author discusses the current Jungian engagement by demonstrating clinical cases in contemporary times. Some Jungian analysts practise I Ching divination to obtain insights into the physical and psychological state of therapeutic relationships and for personal development. This paper is a historical and critical engagement of the Jungian practice of I Ching divination.
