Ductus: A software package for the study of handwriting production

Ductus is a software tool designed to analyze and aid understanding of the processes underlying handwriting production. Ductus is a digitizer-based device that provides online information on the handwriting process. It consists of two distinct modules that operate independently. The first module concerns stimulus presentation. It is particularly suited to experiments with children and patients presenting handwriting pathologies. The second module is devoted to data analysis. Apart from the geometrical aspects of handwriting, such as trajectory formation, Ductus provides a wide range of kinematic information, such as velocity, duration, fluency, and pauses, linked to the mastery of the movement itself. Ductus is available free from the authors. It works on a Windows platform with Wacom digitizers.     

From intentions via planning and behavior to physical exercise habits

ObjectivesIndividuals who enact a health behavior effortlessly with minimal conscious deliberation can be assumed to have formed a healthy habit. This can be reflected by increases in self-reported habit strength of a behavior. We examined whether physical exercise intentions facilitate changes in exercise habit strength by increasing the use of action planning and exercise.DesignTwo field studies investigated the effect of behavioral intentions on changes in habit strength through a sequential path from action planning to exercise.MethodExercise intentions, action planning, habit strength, and exercise were assessed at two measurement points in time in 231 university students (Study 1), and at four points in time in 134 rehabilitation patients (Study 2).ResultsIn multiple-step mediation models in both samples, there were indirect effects of intentions on habit strength through action planning and behavior.ConclusionAction planning and behavior operated as sequential mediators to bridge the gap between intentions and habit strength. Exercise habit strength may increase as a result of conscious action planning and frequent behavior enactment. Including these constructs jointly into behavior change models may improve the understanding of the mechanisms involved in behavior maintenance.     

Group and individual change in the treatment of drug addictions: a follow-up study in therapeutic communities

The pre-post treatment change of 112 patients in two therapeutics Spanish communities is described. The Addiction Severity Index (ASI) was used at intake and at the end of the treatment program. Results of the treatment program were evaluated by applying composite scores (CS) of the ASI, and the evolution of each patient was evaluated using the Reliable Change Index (RCI). 69.7% of the sample completed treatment, and 30.3% dropped out prematurely. At intake, the percentage of people who could improve in the different areas of the ASI ranged between 35.1% for alcohol consumption and 95.3% for family relationships. At the follow-up, the percentage of subjects who showed significant statistical improvements in the different areas varied between 7.9% in family relations and 66.7% in alcohol consumption. The percentage of patients who deteriorated was less than 10% for all variables. Implications for further research and clinical practice are commented upon.

Design and Evaluation of a Decision Aid for Inviting Parents to Participate in a Fragile X Newborn Screening Pilot Study

The major objectives of this project were to develop and evaluate a brochure to help parents make an informed decision about participation in a fragile X newborn screening study. We used an iterative development process that drew on principles of Informed Decision Making (IDM), stakeholder input, design expertise, and expert evaluation. A simulation study with 118 women examined response to the brochure. An independent review rated the brochure high on informational content, guidance, and values. Mothers took an average of 6.5 min to read it and scored an average of 91.1 % correct on a knowledge test. Most women rated the brochure as high quality and trustworthy. When asked to make a hypothetical decision about study participation, 61.9 % would agree to screening. Structural equation modeling showed that agreement to screening and decisional confidence were associated with perceived quality and trust in the brochure. Minority and white mothers did not differ in perceptions of quality or trust. We demonstrate the application of IDM in developing a study brochure. The brochure was highly rated by experts and consumers, met high standards for IDM, and achieved stated goals in a simulation study. The IDM provides a model for consent in research disclosing complicated genetic information of uncertain value.     

The International Affective Digitized Sounds (IADS): Spanish norms

The International Affective Digitized Sounds (IADS): Spanish Norms. The Spanish norms for the International Affective Digitized Sounds (IADS) are reported. The IADS is a standardized set of 110 digitalized sounds which are both reliable and valid for the experimental study of emotional processes. The construction of the IADS is based on Peter J. Lang's dimensional model of emotions. Participants were 1.716 university students (1.136 women) who assessed the sounds using the three scales of the Self-Assessment Manikin: affective valence, arousal, and dominance. The results show a distribution of the sounds, within the bidimensional plot defined by valence and arousal, similar to the North-American student population with a typical boomerang shape. No significant differences were found when comparing men and women nor when comparing the Spanish and North-American samples in the total set of sounds. The results are discussed in relation to the International Affective Picture System (IAPS). The norms for each of the 110 sounds are presented in an annexed table.     

An Integrated Model for the Study of Teacher Motivation

Des recherches récentes ont montré que les enseignants souffraient plus que d’autres groupes professionnels d’un manque de motivation au travail. Une compréhension globale de la motivation des enseignants exige un modèle adéquat. L’objectif principal de cette recherche était de proposer et de mettre à l’épreuve un modèle de la motivation des enseignants qui intégre des concepts de plusieurs théories cognitivo‐motivationelles. Le modèle intégré s’appuie sur la schéma expectation‐valence et celui de l’incapacité acquise, mais surmonte quelques‐unes de leurs imperfections. L’échantillon était composé de 272 enseignants des écoles élémentaires et secondaires du Portugal. Ils ont répondu à une série d’inventaires destinés à mesurer leurs expectations de contrôle, de succès et d’efficacité, leurs attributions, leur motivation intrinsèque, la valence de leurs buts perçus et comment tout ceci interagit pout agir sur l’engagement professionnel (la variable exogène du modèle). Les analyses des coefficients de pistes et de la variance des variables endogènes valident le modèle intégré proposé ici et suggèrent des stratégies de formation pour accroître la motivation des enseignants. Recent studies show that teachers suffer more than other professional groups from the occupational lack of motivation. A global understanding of teacher motivation requires an adequate framework for its study. The main goal of the current research was to propose and test a model of teacher motivation that integrates constructs from several cognitive‐motivational theories. This integrative model starts from the perspectives of Expectancy‐Value and Learned Helplessness but overcomes some of the limitations of each. The participants were 272 elementary and secondary teachers in Portugal. They responded to a series of inventories designed to measure their expectancies of control, success and efficacy, attributions, intrinsic motivation and perceived goal value levels, and how these interact to influence professional engagement (the model's exogenous variable). Analyses of path coefficients and the variance of endogenous variables support the proposed integrated model and suggest strategies for teacher education that may increase teacher motivation.     

Handwriting in patients with Parkinson disease: effect of L-dopa and stimulation of the sub-thalamic nucleus on motor anticipation

The present research focused on how patients with Parkinson’s disease (PD) produce handwriting sequences. PD patients who were on/off medication or deep brain stimulation treatments had to write lll and lln trigrams. We evaluated their ability to anticipate on-line the last letter in the trigram. The results revealed that in PD patients, contrary to healthy participants, the percentage of time taken by the down-stroke of the second l did not vary as a function of the spatial constraints of the following letter (l or n). In other words, the handwriting of the PD patients did not exhibit any sign of motor anticipation. However, under treatment, PD patients exhibited similar results to healthy participants despite no improvement in movement variability. Taken together these results do not seem consistent with the hypothesis that PD patients do not anticipate future movements because of their movement variability. They are more in agreement with theories that postulate that PD patients have a general deficit in the parallel processing of the components of a motor sequence.
