Individuation: finding oneself in analysis--taking risks and making sacrifices

This paper looks at some of the processes that are at work in finding oneself in analysis. It explores Jung's unique contribution to our thinking about the self and its dynamic of individuation. The author attempts to show how the Self, in its quest for consciousness, requires the surrendering of ego inflation--the narcissistic delusion that the ego is the self. A case is made for seeing analysis as an individuation process which offers the opportunity for experiences of a more authentic sense of oneself. Jung stated that individuation requires the ego to enter into service of the Self. For this to happen, the author argues that both patient and analyst must be prepared to make sacrifices and take risks. Using clinical examples, he illustrates that, although purposive, the Self can be experienced as violent and destructive if the ego is unable to facilitate its expression. This may result in an individuation crisis for both analyst and patient. The paper demonstrates how impasse in analysis can evoke the transcendent function, which also requires sacrifices to be made and risks to be taken for analysis to proceed.     

Action-effect coupling in pianists

Recent theories have stressed the role of effect anticipation in action control. Such a mechanism requires the prior acquisition of integrated action-effect associations. The strength of such associations should directly depend on the amount of learning, and therefore be most pronounced in motor experts. Using an interference paradigm, we investigated whether evidence of such representations can be demonstrated in expert pianists. Participants were required to play chords on a keyboard in response to imperative visual stimuli. Concurrently, task-irrelevant auditory stimuli (potential action effects) were presented that were congruent or incongruent with the chords to be played. In Experiment 1 we found evidence that expert pianists, compared with non-musicians, have acquired such action-effects representations. Response times were slower when the auditory stimulus was incongruent with the required response. In order to ascertain the locus of interference, we varied imperative stimuli and responses in Experiments 2 and 3. The results indicate that, for the most part, interference occurs on the response level rather than on an abstract level. However, the perception of action effects also evokes processing of abstract features, like the concept of major–minor mode.     

Task complexity and older adults' decision-making competence

This article reports progress in an ongoing research program examining older adults' decision-making competence (DMC). Using a theoretical framework that emphasizes the person-task fit in assessing DMC, the authors report the results of a study comparing older versus younger adults' decision performance on simple and complex tasks about health, finance, and nutrition. The authors hypothesized and found that increasing age and task complexity were related to greater comprehension errors and inconsistency in decision making. Hierarchical regression analyses showed that a large amount of age-related variance in performance on the decision tasks could be accounted for by exogenous social variables, health measures, basic cognitive skills, and attitudinal measures. The discussion emphasizes several directions for future research, including the need to validate the meaning of performance on these tasks for real-life decision processes.     

Evidence for a gene-environment interaction in predicting behavioral inhibition in middle childhood

Gene-environment interactions are presumed to shape human behavior during early development. However, no human research has demonstrated that such interactions lead to stable individual differences in fear responses. We tested this possibility by focusing on a polymorphism in the promoter region of the gene for the serotonin transporter (5-HTT). This polymorphism has been linked to many indices of serotonin activity. Specifically, we tested the hypothesis that an interaction between children's 5-HTT status and maternal reports of social support predicts inhibited behavior with unfamiliar peers in middle childhood. Results were consistent with this hypothesis: Children with the combination of the short 5-HTT allele and low social support had increased risk for behavioral inhibition in middle childhood.     

Protective and vulnerability factors of depression in normal adolescents

The present study investigated the role of various protective and vulnerability factors in the development of depressive symptoms. A sample of normal adolescents (N=373) completed the Children's Depression Inventory and measures of a negative attributional style, parental rearing behaviour, coping styles, and perceived self-efficacy. In addition to computing the correlations between depression and these protective and vulnerability factors, the present data were also subjected to structural equations modelling to examine the correlational structure of the data. Depression was accompanied by high levels of parental rejection, negative attributions, and passive coping, and by low levels of active coping and self-efficacy. Furthermore, a model in which negative parental rearing behaviour and a negative attributional style featured as the primary sources of depression, while coping styles and self-efficacy played a mediating role in the formation of depressive symptoms, provided a reasonable fit for the data.     

Artificial life and Piaget

Artificial life provides important theoretical and methodological tools for the investigation of Piaget's developmental theory. This new method uses artificial neural networks to simulate living phenomena in a computer. A recent study by Parisi and Schlesinger suggests that artificial life might reinvigorate the Piagetian framework. We contrast artificial life with traditional cognitivist approaches, discuss the role of innateness in development, and examine the relation between physiological and psychological explanations of intelligent behaviour.     

Effect of performance and state orientation on achievement and attention indicators in a simple stimulus-response task with and without performance feedback

In formulating his theory of action control, Kuhl (1983) proposed two motivational states: action orientation and state orientation. People who are action oriented are able to ignore all informations in concrete situations which are irrelevant with regard to the preferred goals. Persons who are state oriented tend to focus sooner on the outlast aspects of a special state. Kuhl introduced a questionnaire HAKEMP to record these tendencies. Further on, there occurs the general assumption that in a particular state of state orientation, people have only a limited processing capacity for given tasks. This hypothesis was tested in an experiment (n = 88) with a stimulus-reaction task. The conditions were varied by the type of the task (fixed or variable stimulus interval) and feedback for the subjects' ability to react. It was expected that for the fixed stimulus interval condition, state-oriented people would be less efficient than action-oriented subjects; with feedback there should be increasing results. The experiment however, shows no significant difference between the performance of state- and action-oriented subjects. These results are discussed in relation to modifications of the HAKEMP questionnaire.     

Diagnostic assessment of cerebrospinal fluid protein in brain and spinal tumors

The cerebrospinal fluid of 69 patients with tumors of the brain and the spine was examined for total protein content, IgG concentration, IgG total protein quotient, and electrophoretic protein pattern. There is no specific finding in the case of the central nervous system. At best characteristic constellations may be established.     

Understanding movement control in infants through the analysis of limb intersegmental dynamics

One important component in the understanding of the control of limb movements is the way in which the central nervous system accounts for joint forces and torques that may be generated not only by muscle actions but by gravity and by passive reactions related to the movements of limb segments. In this study, we asked how the neuromotor system of young infants controls a range of active and passive forces to produce a stereotypic, nonintentional movement. We specifically analyzed limb intersegmental dynamics in spontaneous, cyclic leg movements (kicking) of varying intensity in supine 3-month-old human infants. Using inverse dynamics, we calculated the contributions of active (muscular) and passive (motion-dependent and gravitational) torque components at the hip, knee, and ankle joints from three-dimensional limb kinematics. To calculate joint torques, accurate estimates were needed of the limb's anthropometric parameters, which we determined using a model of the human body. Our analysis of limb intersegmental dynamics explicitly quantified the complex interplay of active and passive forces producing the simple, involuntary kicking movements commonly seen in 3-month-old infants. our results revealed that in nonvigorous kicks, hip joint reversal was the result of an extensor torque due to gravity, opposed by the combined flexor effect of the muscle torque and the total motion-dependent torque. The total motion-dependent torque increased as a hip flexor torque in more vigorous kicks; an extensor muscle torque was necessary to counteract the flexor influences of the total motion-dependent torque and, in the case of large ranges of motion, a flexor gravity torque as well. Thus, with changing passive torque influences due to motions of the linked segments, the muscle torques were adjusted to produce a net torque to reverse the kicking motion. As a consequence, despite considerable heterogeneity in the intensity, range of motion, coordination, and movement context of each kick, smooth trajectories resulted from the muscle torque, counteracting and complementing not only gravity but also the motion-dependent torques generated by movement of the linked segments.
