Form and variability during sit-to-stand transitions: children versus adults

In performing the sit-to-stand transition, young children (6- to 7-year-olds) were expected to display a movement form similar to that of adults. However, movement consistency was predicted to be poorer in children than in adults because they lack refinement of motor control processes. Kinematic analysis of 10 repetitions of the sit-to-stand movement was carried out for 6 typically developing children and 6 adults. Supporting the authors' prediction of comparable form, no differences were evident between age groups for sequence of joint onsets, proportional duration of segmental motion, or in angle-angle plots of displacement at 2 segments. In contrast, within-participant variability was found to be higher for children: Coefficients of variation for most kinematic measures were twice those seen for adults. The authors interpret the children's lack of movement consistency as a reflection of inadequate stabilization of an internal model of intersegmental dynamics. Whereas adults have attained a skill level associated with refinement of that model, children have not. Children have an additional control problem because changes in body morphology throughout childhood require ongoing updating of the internal model that controls intrinsic dynamics.     

Prehension in young children with Down syndrome

Prehension was examined in 3-year old children with Down syndrome (DS, n = 3) and in typically-developing children matched in chronological age (3-year olds; n = 3) or mental age and motor experience (2-year olds; n = 3). The task required reaching to grasp dowels. Video-based movement analysis yielded temporal and kinematic measures. Children with DS were hypothesized to have deficits in feedback-dependent components of prehension (anticipatory grip-closure and deceleration of reach), whereas feedforward components (reach's acceleration phase; grasp's preshaping) were assumed to be unimpaired [Latash, 1993, Control of human movement, pp. 283-292; Latash, 1994, What is clumsiness? In: Motor Control and Down Syndrome II Proceedings of the second international conference, pp. 68-71]. The findings supported these hypotheses. In comparison to control groups, children with DS had significantly: (a) less time in deceleration of reaching, (b) fewer anticipatory grip-closures, and (c) longer movement times for dowel-lift. Young children with DS appeared to use dowel-contact to decelerate the limb and initiate grip-closure. In contrast, reach-acceleration time and grasp-preshaping did not differ across groups. These findings suggest that children with DS display qualitative differences in motor capabilities rather than simply a delayed rate of typical developmental progression.     

Weeds on the Ruins: Agency,Compromise Formation,and the Quest for Intersubjective Truth

Using Kundera's metaphor of “weeds on the ruins” to examine the impact of organized destruction of memory on the survival of a people, this paper explores the role of symptoms in negotiating a relational “compromise formation” by tracing their evolution as signifiers of previously dissociated intersubjective knowledge. It suggests that recent theorizing on the mutual constitution of agency and intersubjectivity creates the possibility of resurrecting the dramatic tension that characterized dual drive theory by relocating that tension between the desire to know (oneself, the Other) and the destruction of that desire. To do so, the paper contemplates an internally consistent lens for reconciling the terrain of deficit and dissociation with that of conflict by offering a process-oriented view of agency as “drive” that is rooted between subjective and material contexts. Finally, the paper explores the quest for intersubjective truth as offering a means of living beyond the ubiquity of compromise formation.     

Evaluating the effect of educational media exposure on aggression in early childhood

Preschool-aged children (M = 42.44 months-old, SD = 8.02) participated in a short-term longitudinal study investigating the effect of educational media exposure on social development (i.e., aggression and prosocial behavior) using multiple informants and methods. As predicted, educational media exposure significantly predicted increases in both observed and teacher reported relational aggression across time. Follow-up analyses showed that educational media exposure also significantly predicted increases in parent reported relational aggression across more than a two year period. Results replicate and extend prior research that has demonstrated links between educational media exposure and relational aggression, but not physical aggression, during early childhood.     

Loss and change in primary care: Working with organisational anxiety

This paper will consider the identity of an inner voice that is experienced by everyone, but in very different ways. However, when working in the transference with psychotic patients the boundaries of personal identity and the question of choice and volition are so compromised by the illness that the phenomena are so to speak ‘writ large’. This allows the issues to be brought out with great vividness and intensity and it is the struggle with this that has led me to reconsider the identity of the inner voice in a way which I have found useful for the rest of my clinical work.

Prior to 1985, my clinical work with patients with psychotic illnesses was undertaken in the in-patient psychotherapy ward at Shenley Hospital that I was responsible for. With the movement of psychotherapy resources out of Shenley to set up the Willesden Centre, our ability to continue with this work was very compromised because the Centre is entirely an out-patient resource. However, a number of us persevered and gradually worked out ways to be able to continue to offer treatment to patients who had psychotic illnesses. This involved the establishment of a case-manager system to enable the therapist to work in the transference. This evolution has occurred in a specialist workshop that I have been running at the Willesden Centre since 1986.     

The relationship between productive and counterproductive work behaviour across four European countries

Research suggesting a similar but different relationship between Organizational Citizenship Behaviour (OCB) and Counterproductive Work Behaviour (CWB) is dominated by North American samples. Little evidence exists on whether these findings are replicated in other countries. To assess if a similar pattern emerged, we used the Social Axioms model (Bond et al., 2004) as a cultural framework and surveyed employees in the UK (105), The Netherlands (203), Turkey (185), and Greece (70) on the relationship between OCB and CWB, and the relationship between these behaviours and personality, justice, and commitment. Analysis supported a multidimensional structure to OCB and CWB and indicated a nonbipolar relationship between these behaviours. Culturally, somewhat different to OCB research in general, we find support for a convergence perspective across countries. Conceptually, linguistically and structurally the scale assessing OCB/CWB was shown to be equivalent across countries and a nonbipolar pattern of relationships was consistent across countries. Overall, findings imply a universal nature to the relationship between OCB and CWB across societal cultural groups.
