Non-linear gaining in precision aiming: making Fitts' task a bit easier

The role of information in the processes underlying kinematic trajectory-formation was examined by manipulating the relation between effector space (movement of a hand-held stylus on a graphics tablet) and task space (movement of a cursor on a screen where targets were presented) in a precision aiming task with five different levels of task difficulty. Movement patterns were found to evolve as a function of the flow of information in task space, with participants (N = 13) producing more rapid and more fluent movements when the mapping between spaces included the softening-spring characteristics typical of behavioural patterns at higher levels of task difficulty. We conclude that the kinematic changes (movement time and pattern) observed when task difficulty increases result from informational influences. Information affects behavioural dynamics at the level of the parameters without affecting the underlying dynamical structure.     

Adolescent Conduct Problems and Bulimic Tendencies: Study of an Emotional Distress Hypothesis

Prior research has documented an association between adolescent conduct problems and bulimic tendencies. However, there is limited theoretical modeling to explain this association, and prior studies have generally failed to assess for potential mediating variables of impulsivity, anxiety, and depression. The current study assessed these mediating variables in further exploring for unique associations between adolescent conduct problems and bulimic tendencies. A non-referred adolescent sample was assessed for bulimic tendencies, conduct problems, impulsivity, anxiety, and depression using a multi-informant assessment battery including parent, teacher, and self-report measures. There was a significant bivariate association between conduct problems and bulimic tendencies, r = 0.29, p < 0.01. However, this association was fully mediated by anxiety and depression symptoms. This suggests that emotional distress could be a primary factor linking adolescent conduct problems and bulimic tendencies. Implications include the potential for more regular screening of youth with conduct problems for associated eating disturbances.

Would We Recognize Progress if We Saw it? A Commentary

Comments on the nature of special education as an enterprise and judgment of its progress are offered. Five independent but necessary and sufficient criteria for judgment of progress in special education for students with emotional or behavioral disorders are suggested. Comments are made on each of the articles in the series, and concluding remarks call for more data and better thinking.     

Ethics Consultation and Autonomy

Services of ethics consultants are nowadays commonly used in such various spheres of life as engineering, public administration, business, law, health care, journalism, and scientific research. It has however been maintained that use of ethics consultants is incompatible with personal autonomy; in moral matters individuals should be allowed to make their own decisions. The problem this criticism refers to can be conceived of as a conflict between the professional autonomy of ethics experts and the autonomy of the persons they serve. This paper addresses this conflict and maintains that when the nature of both ethics consultation and individual autonomy is properly understood, the professional autonomy of ethics experts is compatible with the autonomy of the persons they assist.     

Study on the relations between temperament,aggression, and anger in children

The present work analyzes the relationships between the dimensions of temperament and the exteriorized emotions of aggression and anger. Temperament was assessed by mothers using the Dimensions of Temperament Survey‐Revised, while aggression and anger were self‐reported by the children using the Scale of physical and Verbal Aggression and the State–Trait Anger Expression Inventory for Children. The sample studied was made up of 293 children (49.83% boys; 50.17% girls) with a mean age of 11.13 years. The results showed that temperamental difficulties give rise to exteriorized emotions, especially anger. Predictive values of temperament on aggression and anger ranged from 1% to 7% of explained variance. Aggr. Behav. 32:207–215, 2006. © 2006 Wiley‐Liss, Inc.     

What Do Women Want? A New View of Women’s Sexual Problems

Recent attempts to medicalize women’s sexual “dysfunction” are critiqued and a “New View” of women’s sexual problems is introduced. The author argues for a female-centered perspective on women’s sexual desires and problems, based on a review of the literature on women’s sexuality and her observations of young women’s sexual experiences from 25 years of teaching Human Sexuality to undergraduate women. The review suggests that a pill or a patch cannot adequately address the sexual problems commonly experienced by US women.     

From BIS/BAS to the big five

Gray ( 1987 ) proposed two systems that underlie much of our behaviour and personality. One system relates to avoidance or withdrawal behaviour, called the Behavioural Inhibition System (BIS), whereas the other system relates to approach behaviour, called the Behavioural Approach System (BAS). In two samples, it was investigated whether individual differences in surface of personality as described by the Big Five can be explained by BIS/BAS. Neuroticism and Extraversion could be explained well by BIS/BAS, but also for Agreeableness and Conscientiousness consistent findings were obtained. Copyright © 2006 John Wiley & Sons, Ltd.

小学生的品德不良行为及其心理与行为适应问题研究

运用测量法和问卷法,以某市357名小学生为对象,探讨了小学生的品德不良行为及其心理问题与行为适应性问题,并揭示了它们之间相互的关系。结果发现:小学生的品行不良、心理健康问题和行为适应问题都存在显著的年级差异,并受学习成绩的显著影响:成绩差的学生在这些问题上最严重;且品行不良和学习问题存在显著的性别差异;小学生的品德不良水平与许多心理问题之间存在显著相关;五年级是一个转折点:在品德不良行为和许多心理问题中都是高峰,随后开始下降。
