Heinz Werner: His Life,Ideas, and Contributions to Developmental Psychology in the First Half of the 20th Century

ABSTRACT

The author provides an overview of Heinz Werner's life and contributions to the field of developmental psychology during the first half of the 20th century. She focuses on his early work in Vienna and Munich as well as his tenure at the Psychological Institute in Hamburg, up through the time when he became a named Professor in Psychology at Clark University. Recognized as one of the founders of developmental psychology, Heinz Werner worked in the areas of perceptual development, comparative psychology, and symbol formation. Versatile in rigorous experimental methodologies, and in observational and phenomenological methodologies, Werner's approach to development stood in contrast to other approaches of development, both past and current. For Werner, development was a heuristic, a way of looking at processes in a variety of domains, including ontogeny, phylogeny, microgenesis, biology, developmental psychopathology, neuropsychology, and comparative psychology. Werner viewed development as proceeding from a state of relative globality and lack of differentiation to a state of increasing differentiation, articulation, and hierarchical integration, but he also stressed that individuals can function at different developmental levels under different times and conditions. Werner's holistic, organismic, comparative, and contextual approach to development transcended interdisciplinary boundaries, allowing him to study the interrelatedness between thought, language, feeling, perception, and culture.     

Action planning and position sense in children with Developmental Coordination Disorder

The present study examined action planning and position sense in children with Developmental Coordination Disorder (DCD). Participants performed two action planning tasks, the sword task and the bar grasping task, and an active elbow matching task to examine position sense. Thirty children were included in the DCD group (aged 6–10 years) and age-matched to 90 controls. The DCD group had a MABC-2 total score ⩽5th percentile, the control group a total score ⩾25th percentile. Results from the sword-task showed that children with DCD planned less for end-state comfort. On the bar grasping task no significant differences in planning for end-state comfort between the DCD and control group were found. There was also no significant difference in the position sense error between the groups. The present study shows that children with DCD plan less for end-state comfort, but that this result is task-dependent and becomes apparent when more precision is needed at the end of the task. In that respect, the sword-task appeared to be a more sensitive task to assess action planning abilities, than the bar grasping task. The action planning deficit in children with DCD cannot be explained by an impaired position sense during active movements.     

Comparison of motor praxis and performance in children with varying levels of developmental coordination disorder

The praxis test is a less well-documented method to determine functional manifestations of childhood dyspraxia. For this study, children aged 6–8 years were recruited as follows: 17 children with DCD, 18 at risk of DCD and 35 without obvious problems in motor coordination. The Movement Assessment Battery for Children (MABC-2) was used to measure motor performance and identify the motor incoordination. This study developed a battery of tests to assess limb praxis using a praxis imagery questionnaire, gesture representation, and questions about knowledge of object use. In the comparison of subtests within the praxis test, significant differences were observed across groups on the praxis imagery questionnaire and gesture representation tests but not on knowledge of object use. Similar results were observed in the correlation analyses, in which a weak relationship between MABC-2 and praxis tests was observed. The DCD group had lower scores on the praxis imagery questionnaire, whereas the group at risk of DCD had lower scores on most gesture production tests. Our study provides a better understanding of the nature of the childhood dyspraxia and sheds light on its effect on motor coordination to identify praxis tests with specific clinical meanings in children with movement disorders.     

The benefits of retail therapy: Making purchase decisions reduces residual sadness

People often shop when feeling sad, but whether and why shopping reduces residual (lingering) sadness remains an open question. Sadness is strongly associated with a sense that situational forces control the outcomes in one's life, and thus we theorized that the choices inherent in shopping may restore personal control over one's environment and reduce residual sadness. Three experiments provided support for our hypothesis. Making shopping choices helped to alleviate sadness whether they were hypothetical (Experiment 1) or real (Experiment 2). In addition, all experiments found support for the underlying mechanism of personal control restoration. Notably, the benefits of restored personal control over one's environment do not generalize to anger (Experiments 2 and 3), because anger is associated with a sense that other people (rather than situational forces) are likely to cause negative outcomes, and these appraisals are not ameliorated by restoring personal control over one's environment.     

Commentary on Meehl

The classic article by Meehl (1978) raises fundamental issues regarding the viability of theorizing in the “soft” psychological sciences and the weakness of statistical significance testing in appraising the validity of the field’s theories. These concerns are as valid today as they were a quarter of a century ago. Despite the lack of clear progress that has been made in terms of theory building, I raise several examples from developmental psychopathology research that reveal progress in the field’s conceptual and methodologic rigor, including the testing of genotype by environment interactions, the statistical advances driving longitudinal research, and the use of intervention and prevention trials to address questions of etiology and mechanisms related to psychopathology.     

Does gender affect Bayley-III scores and test-taking behavior?

The developmental test Bayley-III is widely used in clinical and research settings, but there are no published gender-specific norms. The purpose of the present study was to investigate gender differences in Bayley-III scores in a sample of 55 typically developing children assessed repeatedly at ages 4, 7, 10, 13, 24 and 36 months, and to investigate gender differences in the test-taking behavior of the children as measured with the BRS at 36 months. The results of the study demonstrated gender differences at 24 and 36 months for the Cognitive Scale, at 10, 13, 24 and 36 months for the Language Scale and at 36 months for the Motor Scale. On a subtest level, gender differences were found for the Receptive Communication subtest at 13, 24 and 36 months and for the Fine Motor subtest at 7 and 36 months. In all cases where significant gender differences were found, girls achieved higher mean scores than boys. No gender differences were found in the children’s test-taking behavior at 36 months on any of the BRS scales, but independently of gender, higher Bayley-III Cognitive and Motor Scale scores were associated with more compliant test-taking behavior.     

Investigation of fine motor performance in children younger than 36-month-old using PDMS-2 and Bayley-III

ABSTRACT

The aim of the study was to investigate the concurrent validity of fine motor (FM) development scores between the Peabody Developmental Motor Scales, Second Edition (PDMS-2), and Bayley Scale of Infant and Toddler Development, Third Edition (Bayley-III). Both tests were administered to 223 children aged 13–36 months with suspected developmental delays from a medical centre. Concurrent validity and agreement of FM delay were assessed. The Bayley-III FM scale scores (FMSS) and motor composite quotients were moderately correlated with PDMS-2 FM quotients. The agreement of FM delay between the two instruments was excellent (Kappa coefficient value = .80) in children aged 13–18 months and good in children aged 19–36 months. When using PDMS-2 as the reference standard, Bayley-III (FMSS < 7) identified fewer children aged 19–24 months as delayed but more in children aged 25–36 months as delayed. When adjusting the cut-off point of Bayley-III FMSS to 8 for children aged 19–24 months and to 6 for children aged 25–36 months, the agreement improved between these two instruments. FM delays might be underestimated solely using Bayley-III in children aged 19–24 months. Additional tests, such as PDMS-2 should be considered to avoid delays in accessing early intervention services.     

Green with envy and nerves of steel: Moderated mediation between distributive justice and theft

The relationship between distributive justice and theft is well established, but the underlying mechanism for this relationship is not yet well understood. We expect that the discrete emotions that individuals experience when they have been paid unfairly may influence how they behave and their personality traits help them cope with unfair pay. In the present study, we therefore use the appraisal model to examine which discrete emotion (i.e., anger, disappointment, and envy) mediates the relationship between distributive justice and theft and conservation of resources theory to examine how emotionality is a personal resource that varies among individuals to help them cope with unfair pay. Participants were randomly assigned to an experimental condition where we manipulated the fairness of the pay that they received, measured the discrete emotions that they felt after being informed of their pay, and objectively measured how much they stole. The results indicate that envy mediates the relationship between distributive justice and theft and there is a moderating effect of emotionality on distributive justice and envy; and envy and theft. Theoretical and practical implications of the findings are discussed.
