Radial bisection of words and lines in right‐brain‐damaged patients with spatial neglect

The bisection of lines positioned radially (with the two ends of the line close and far, with respect to the participant's body) has been less investigated than that of lines placed horizontally (with their two ends left and right, with respect to the body's midsagittal plane). In horizontal bisection, patients with left neglect typically show a rightward bias for both lines and words, greater with longer stimuli. As for radial bisection, available data indicate that neurologically unimpaired participants make a distal error, while results from right‐brain‐damaged patients with left spatial neglect are contradictory. We investigated the bisection of radially oriented words, with the prediction that, during bisection, linguistic material would be recoded to its canonical left‐to‐right format in reading, with the performance of neglect patients being similar to that for horizontal words. Thirteen right‐brain‐damaged patients (seven with left spatial neglect) and fourteen healthy controls were asked to manually bisect 40 radial and 40 horizontal words (5–10 letters), and 80 lines, 40 radial and 40 horizontal, of comparable length. Right‐brain‐damaged patients with spatial neglect exhibited a proximal bias in the bisection of short radial words, with the proximal part corresponding to the final right part of horizontally oriented words. This proximal error was not found in patients without neglect and healthy controls. For bisection, short radial words may be recoded to the canonical orthographic horizontal format, unveiling the impact of left neglect on radially oriented stimuli.     

Power of the desired self: Influence of induced perceptions of the self on reasoning

This research shows that the motivation to posses a desired characteristic (or to avoid an undesired one) results in self-perceptions that guide people’s use of base rate in the Lawyer–Engineer problem (Kahneman & Tversky, 1973). In four studies, participants induced to believe (or recall, Exp. 2) that a rational cognitive style is success-conducive (or an intuitive cognitive style failure-conducive) subsequently viewed themselves as more rational and relied more on base rate in their probability estimates than those induced to believe that a rational cognitive style is failure-conducive (or an intuitive cognitive style success-conducive). These findings show that the desired self had an influence on reasoning in the self-unrelated lawyer–engineer task, since the use of base rates was mediated by changes in participants’ perceptions of their own rationality. These findings therefore show that the desired self, through the working self-concept that it entails, constitutes another factor influencing people’s use of distinct modes of reasoning.     

Silicon in ‘pure gold’? Theoretical contributions and observations on teleanalysis by videoconference

Ideas about psychoanalysis via videoconference—videoconference teleanalysis (VT)—are presented with the general understanding that these settings produce a twofold split between various degrees of recognition/negativisation of the absence of the other, on one hand, and the expectation of physical co‐presence, on the other. This split has been put forward as dismantling the here, now, with me pre‐reflexive unity of the analytic experience. This article suggests that both members of the analytic dyad will seek to reappropriate the experience through a forced ego integration that interferes with accessing states of unintegration in the analytic treatment and produces subtle alterations to symbolisation work. The effort to overcome this condition is illustrated with clinical vignettes and therapists’ comments about feelings of inauthenticity and discontent when trying to sustain evenly‐suspended attention, as well as in the perception of a form of flattening of the alive nature of speech. However, this is not a constant for all VT, and mutual understanding can be an important mitigating feature. The focus of the discussion should be on the capacity of the analytic dyad to overcome such a split and not on a direct extrapolation of the perceptual limitations of VT to possible effects on transference / countertransference.     

Poor Imitative Performance of Unlearned Gestures in Children with Probable Developmental Coordination Disorder

It has been hypothesized that deficits in imitation, linked to abnormal functioning of the mirror neuron system (MNS), may contribute to the motor impairments associated with developmental coordination disorder (DCD). The authors aimed to examine imitation of complex novel postures and sequences of gestures in children with and without probable DCD (pDCD), using the postural praxis and sequencing praxis subtests of the Sensory Integration and Praxis Tests (Ayres, 1989 Ayres, A. J. (1989). Sensory Integration and Praxis Tests: SIPT manual. Los Angeles, CA: Western Psychological Services. [Google Scholar]). Participants were 29 boys with pDCD between 6.08 and 13.33 years old, and 29 group age-matched typically developing boys between 6.08 and 13.83 years old. Responses of children with pDCD on both imitation tasks were less accurate than controls, with group differences more apparent with increasing task complexity. Furthermore, as a group, children with pDCD were slower and had a higher number of non–mirror-imitated responses. There was considerable variability within the pDCD group, with some children displaying imitation scores within the normative range. Given the importance of imitation and visual learning for motor development, the difficulties in imitation displayed by some children with pDCD have the potential to impact on movement acquisition. Interventions to target imitation may be beneficial for these children. The results show that children with pDCD had difficulty imitating complex novel postures, children with pDCD had difficulty imitating gesture sequences, children with pDCD had slower responses than controls, group differences in imitation performance increased with task complexity, and not all children with pDCD displayed imitation deficits.     

The Effects of Sensory Manipulations on Motor Behavior: From Basic Science to Clinical Rehabilitation

Modifying sensory aspects of the learning environment can influence motor behavior. Although the effects of sensory manipulations on motor behavior have been widely studied, there still remains a great deal of variability across the field in terms of how sensory information has been manipulated or applied. Here, the authors briefly review and integrate the literature from each sensory modality to gain a better understanding of how sensory manipulations can best be used to enhance motor behavior. Then, they discuss 2 emerging themes from this literature that are important for translating sensory manipulation research into effective interventions. Finally, the authors provide future research directions that may lead to enhanced efficacy of sensory manipulations for motor learning and rehabilitation.     

Child Maltreatment,Problem Behaviors,and Neighborhood Attainment

Using data from a prospective cohort design study of a group of children with documented histories of abuse and neglect (n = 908) and matched controls (n = 667), this paper examines whether problem behaviors (e.g., prostitution, crime, school problems, and homelessness) in young adulthood explain the link between maltreatment in childhood and living in high‐risk neighborhoods in middle adulthood. Problem behaviors were assessed at mean age of 29 and neighborhood characteristics were assessed at mean age of 40. Child maltreatment predicted living in less desirable neighborhoods in middle adulthood. Problem behaviors in young adulthood partially mediated the relationship between childhood maltreatment and residence in less desirable neighborhoods in middle adulthood. The direct paths from child maltreatment to neighborhoods were not significant for Black children. For White children, there was a direct relationship between child maltreatment and living in an economically disadvantaged neighborhood. Problem behaviors were a stronger mediator between child maltreatment and living in more disordered and less socially cohesive neighborhoods for Black children, while the problem behaviors were a stronger mediator for living in more economically disadvantaged and less socially cohesive neighborhoods for White children. Further research is needed to understand these racial differences. Interventions should focus on preventing problem behaviors to minimize the risk of residency in high‐risk neighborhoods.     

Not Just Right Experiences: Association with Obsessive Compulsive Symptoms and Sensory Over-Responsivity

Individuals with obsessive-compulsive disorder describe “not just right experiences” as a constant uncomfortable feeling of imperfection toward sensory stimuli. This study examined the relation between “not just right experiences,” obsessive-compulsive disorder and sensory over-responsivity symptoms. Sixty college students participated in the in vivo “not just right experiences” assessment. This included four tasks for which participants rated pre-task discomfort, post-task discomfort, and urge to counteract auditory, visual, and tactile stimuli. “Not just right experiences” scores significantly correlated with obsessive-compulsive disorder scores. Tactile, auditory, and visual sensory over-responsivity scores were correlated with specific “not just right experiences” scores. Sensory over-responsivity is rarely addressed in obsessive-compulsive disorder while it contributes to symptomatology and participation.     

Rage and hatred in infants: conditions which facilitate development versus those which result in tragic delays or alarming distortions

The paper traces some possible trajectories of aggressive behaviour in children and adolescents. It distinguishes three contributing factors: 1. Disturbance or Disorder; 2. Deficit and Neglect; and 3. Deviance. Therapeutic technique may need adjusting depending on which factor is dominant at any moment. Two dimensions which seem to run through these categories are first, the question of which type of violence is occurring - that is, the motivation and emotion which accompany the violence; the second question is whose violence: that is, when we study the inner world of aggressive children we discover vast differences in the relationships between the self and the internal objects or representational figures of other people. These two questions will be raised whenever we try to treat these children or adolescents.     

Withholding Effort in Organizations: Toward Development and Validation of a Measure

Field research into the topic of withholding effort and its variants (shirking, loafing, free riding, and job neglect) has been limited due to a lack of measures that are applicable to organizational settings. This study used a multi-phase process to ascertain a measure of withholding effort that can be used in organizational settings. Items were generated through literature review and discussions with practitioners; culled by the authors; and tested in a field study in multiple, diverse organizations. Exploratory and confirmatory factor analyses found the construct of withholding effort to be multidimensional, but not necessarily as previous theoretical work in the area would suggest. Correlations of the various dimensions of withholding effort scales with existing scales tapping a wide range of employee attitudes were consistent with a priori expectations. Implications for the use of these scales in future workplace research and their practical application in organizations are discussed.     

客体复杂度影响工作记忆可存储的客体数目

采用变化觉察范式,以对侧延迟活动（contralateral delay activity,CDA）的幅值为指标,通过操纵记忆刺激的复杂程度,对视觉工作记忆中可存储的客体数目（即工作记忆容量）问题进行了探讨。结果表明,2个复杂客体条件下的CDA幅值与4个复杂客体条件无显著差异,而4个简单客体条件的CDA幅值显著高于2个简单客体条件,即CDA的幅值受客体复杂度的调节。基于该结果推论：并非视觉工作记忆总能存储4个客体,其可存储的客体数目受客体复杂度影响。
