The micro-structure of tapping movements in children

In order to investigate the development of movement speed in relation to movement organization, children of 5, 6, 7, 8 and 9 years of age and adults carried out a reciprocal tapping task, in which time pressure and distance were manipulated. The duration, velocity, acceleration and accuracy of the movements were compared between age groups. Age differences appeared mainly in the homing time, not in the duration of the distance covering movement phase. Accuracy and velocity of the distance covering movement phase differed with age. Time pressure affected the homing time, but not the duration of the distance covering phase. Distance manipulation affected mainly the velocity and duration of the distance covering movement phase and the homing time. In the discussion it is contended that age differences in homing time may be related to both the accuracy of the distance covering movement phase and the rate of information processing of the subject.

The reduction of anxiety in children: a comparison of the effects of 'systematic desensitization in vitro' and 'systematic desensitization in vivo'

Twenty-four children between the ages of 5 and 10. selected on the basis of fear of water, as determined by parents and swimming teachers, were divided into two experimental groups and one control group. One of the experimental groups was treated with four sessions of in vitro desensitization (gradual imaginal exposure to fear evoking stimuli plus relaxation), followed by four sessions of in vivo desensitization (real-life exposure to fear evoking stimuli plus relaxation). The other group received eight sessions of in vivo desensitization. The control group took part only in the tests, which were administered at the commencement of treatment, after four sessions, and at the end of the course of treatments. In testing, a behavior observation record was used to score the subject's behavior in the given situation; in addition, two teacher's records were used, in which swimming teachers recorded their evaluation of the subject's anxiety in each situation.Better results were achieved by desensitization in vivo than by desensitizalion in vitro or by the control procedure. No differences were found between the latter two groups. It could not be demonstrated that desensitization in vitro increased the effectiveness of subsequent desensitization in vivo     

Predictors for re-employment success in newly unemployed: A prospective cohort study

The aim of the present study was to examine which personal and situational factors affect reemployment success in persons in their first year of unemployment. In a prospective cohort study with a one-year follow-up, we investigated a sample of 3618 subjects who became unemployed. A survey was sent to all participants, including personal and situational factors, based on Wanberg's model, the Theory of Planned Behavior model and the Valence–Instrumentality–Expectancy model. Our results showed that ten key-factors predicted re-employment success in the first year after becoming unemployed. Knowing these factors, and in particular those which are amenable to change through any intervention program, may help to develop effective intervention strategies for those who facilitate reemployment in order to shorten the duration of unemployment.
