Impact forces cannot explain the one-target advantage in rapid aimed hand movements

A pointing movement is executed faster when a subject is allowed to stop at the first target than when the subject has to proceed to a second target ("one-target advantage"). Our hypothesis was that this is because the impact at the target helps to stop the finger when the finger does not have to proceed to a second target. This hypothesis would predict that the horizontal force at contact with the first target should be larger when there is only one-target. Modelling smooth movements with larger forces at contact using a minimum-jerk model, shows that the peak velocity is slightly higher and it occurs later during the movement when there is only one target. Although the one-target advantage was present in our experiment, the horizontal force at contact in the one-target condition was not larger than in the two-target condition. The time of the maximum velocity did not differ, but the maximum velocity was higher in the one-target condition. Thus our hypothesis is rejected, favouring a non-mechanical explanation of the one-target advantage.     

Responsiveness to terrestrial optic flow in infancy: does locomotor experience play a role?

Human infants show a peak in postural compensation to optic flow at approximately nine months of age. The current experiment tested whether the magnitude of visual-postural coupling in 9-month-olds increases when terrestrial optic flow is added to a moving room. A secondary objective was to explore whether locomotor experience plays any role in enhancing responsiveness to the additional terrestrial information. Ninety-one infants (experienced creepers, nascent creepers, and prelocomotors) were exposed to two conditions of optic flow: global optic flow (G) and global optic flow minus terrestrial optic flow (G-T). The additional terrestrial optic flow led to significantly higher visual-postural coupling. Consistent with previous findings, locomotor experience had no effect on responsiveness to the G-T condition, though there was weak evidence that the nascent creepers were more strongly influenced by the difference between flow conditions than the other infants. Unexpectedly, the prelocomotor females showed significantly lower visual-postural coupling than the prelocomotor males. These findings support the notion that the ground provides an important source of information for the control of posture and locomotion. The findings also suggest that locomotor experience most likely helps to functionalize smaller (partial), rather than larger (global), optic flow fields for postural control.     

Are preschoolers sensitive to configural information in faces?

Several researchers have proposed that developmental improvements in children's face recognition abilities might reflect an increasing reliance on configural information (i.e. spatial relations between features) in faces (Carey & Diamond, 1994; Mondloch, Le Grand & Maurer, 2002). We investigated 4- and 5-year-olds' use of configural information for upright and inverted faces using Tanaka and Sengco's (1997) configural change paradigm. Participants saw a photograph of a child's face (e.g. Luke). Memory for features (e.g. Luke's mouth) was then tested in a face with the same configuration as the study face (e.g. Luke's face), in a face with a novel spatial configuration (e.g. Luke's face with the eyes shifted further apart), and presented on their own (e.g. Luke's mouth alone). We found that preschoolers and adults recognized target features from upright faces better when tested in the context of a face with the same configuration as the study face, than when they were embedded in a face with a new spatial configuration or when they were presented in isolation. This effect was lost when faces were inverted. The results suggest that adult-like styles of face processing are present from 4 years of age.     

Training in family psychology: a competencies-based approach

After providing an overview of the family psychology landscape and the competencies-based movement in professional psychology, attention is paid to eight family-specific competencies in the following areas: the application of scientific knowledge to practice, psychological assessment, psychological intervention, consultation and interprofessional collaboration, supervision, professional development, ethics and legal issues, and individual and cultural diversity. Effective strategies for providing family-focused education and training to psychology trainees at the doctoral, internship, and postdoctoral levels and to psychologists through continuing professional education in these core competency domains are provided.     

Child care under pressure: the quality of Dutch centers in 1995 and in 2001

In 2001, the authors assessed the quality of care provided to children in 51 care groups from 39 child-care centers in The Netherlands using the Infant/Toddler Environment Rating Scale (T. Harms, D. Cryer, & R. M. Clifford, 1990) and compared the results with the quality of child care assessed in 1995 (M. H. van IJzendoorn, L. W. C. Tavecchio, G. J. Stams, M. J. E. Verhoeven, & E. J. Reiling, 1998). The overall quality and scale scores for language and learning activities were significantly lower in 2001 than in 1995. Child-care centers founded within the past 6 years (all nonsubsidized centers) scored considerably lower than did older, mostly subsidized, centers. The results are discussed from the perspective of changes in the socioeconomic and political context of child care.     

Biological Sex and Psychological Gender as Predictors of Routine and Strategic Relational Maintenance

The current study contributes to 2 growing areas of research: one distinguishes between routine and strategic relational maintenance behaviors, and the other concerns the relative utility of biological sex and psychological gender as predictors of communication behaviors. Specifically, we sought to uncover sex and gender differences in routine and strategic maintenance and to test the relative strength of each as predictors of routine and strategic maintenance. Survey data were collected from 189 individuals in romantic relationships. Results indicated only one sex difference; women use routine openness more than men do. However, femininity was positively associated with the routine use of advice, conflict management, and openness. Masculinity was positively associated with the strategic use of openness and tasks. Femininity was not associated with strategic maintenance, and masculinity was not associated with routine maintenance. The value of distinguishing between sex and gender to explain how individuals function in relationships is discussed.     

Confirmatory factor analysis of the behavior rating inventory of executive function in a neuro-pediatric sample and its application to mental disorders

The construct validity of the 9-scale version of the Behavior Rating Inventory of Executive Function (BRIEF) parent form was examined in a clinical sample of children and adolescents with neurological and neurodevelopmental disorders (N = 281). Confirmatory factor analysis supported a three-factor model separating the inhibitory behavioral control dimension from the emotional control and metacognitive problem-solving dimensions. The Metacognitive factor was also related to a diagnosis of attention deficit/hyperactivity disorder (ADHD) after controlling for age, gender, IQ, adaptive functioning, and a conventional behavioral rating scale, which included inattention-hyperactivity symptoms. The Emotional Regulation factor was related to a diagnosis of oppositional defiant disorder. Correlational analyses indicated that child comorbid emotional and behavioral problems may exacerbate parental BRIEF reporting. Accordingly, when assessing executive function among children with neurological and neurodevelopmental disorders, the BRIEF should be complemented with assessments of mental health problems.     

How to study the ‘quality of psychoanalytic treatments’ and their long‐term effects on patients' well‐being: A representative,multi‐perspective follow‐up study3

How can we study the ‘quality of psychoanalytic treatments’? The authors attempt to answer this question by discussing a naturalistic, multi‐perspective and representative follow‐up study of psychoanalyses and long‐term psychoanalytic psychotherapies. We studied a representative sample (n = 401) of all the patients who had terminated their psychoanalytic treatments with members of the German Psychoanalytical Association (DPV) between 1990 and 1993. Between 70 and 80 per cent of the patients achieved (average 6.5 years after the end of treatment) good and stable psychic changes according to the evaluations of the patients themselves, their analysts, independent psychoanalytic and non‐psychoanalytic experts, and questionnaires commonly applied in psychotherapy research. The evaluation of mental health costs showed a cost reduction through fewer days of sick leave during the seven years following the end of long‐term psychoanalytic treatments. The results achieved using non‐psychoanalytical instruments are complemented by the richness of the idiosyncratic findings, gained by the psychoanalytic research instruments.

Automatic identification of storytelling responses to past-behavior interview questions via machine learning

Structured interviews often feature past-behavior questions, where applicants are asked to tell a story about past work experience. Applicants often experience difficulties producing such stories. Automatic analyses of applicant behavior in responding to past-behavior questions may constitute a basis for delivering feedback and thus helping them improve their performance. We used machine learning algorithms to predict storytelling in transcribed speech of participants responding to past-behavior questions in a simulated selection interview. Responses were coded as to whether they featured a story or not. For each story, utterances were also manually coded as to whether they described the situation, the task/action performed, or results obtained. The algorithms predicted whether a response features a story or not (best accuracy: 78%), as well as the count of situation, task/action, and response utterances. These findings contribute to better automatic identification of verbal responses to past-behavior questions and may support automatic provision of feedback to applicants about their interview performance.
