Growth in temperament and parenting as predictors of adjustment during children's transition to adolescence

The author examined relations among demographic risk (income, maternal education, single-parent status), growth in temperament (fear, irritability, effortful control), and parenting (rejection, inconsistent discipline) across 3 years and the prediction of children's adjustment problems in a community sample (N=190; ages 8-12 years at Time 1). Family income was related to higher initial levels of fear, irritability, rejection, and inconsistency and lower effortful control but was not related to changes in these variables. Higher initial rejection predicted increases in child fear and irritability. Higher initial fear predicted decreases in rejection and inconsistency. Higher initial irritability predicted increases in inconsistency, and higher initial effortful control predicted decreases in rejection. When growth of parenting and temperament were considered simultaneously, increases in effortful control and decreases in fear and irritability predicted lower Time 3 internalizing and externalizing problems. Increases in rejection and inconsistent discipline predicted higher Time 3 externalizing, although sometimes the effect appeared to be indirect through temperament. The findings suggest that temperament and parenting predict changes in each other and predict adjustment during the transition to adolescence.     

On shame and the perceived credibility of sexual assault allegations

Despite the high incidence of sexual assault, doubt about allegations is common. Previous research suggests that victims expressing positive or no emotion are perceived as less credible than those expressing negative emotions. However, little is known about which specific negative emotional expressions contribute to credibility in this context. In two studies (N = 623), participants read a date rape vignette. The alleged victim's statement was paired with a picture of a female person expressing either shame, sadness, or no emotion. Participants rated the credibility of her account and completed a measure of rape myth acceptance. Controlling for rape myth acceptance, allegations were perceived as more credible when accompanied by an expression of shame versus sadness (a negative, low arousal control condition). It is critical to be aware of the shame-credibility bias in this context to intervene and support those who have experienced sexual assault.     

Self-regulation as a moderator of the relation between coping and symptomatology in children of divorce

Investigated the effects of self-regulation as a moderator of the relations between coping efforts and psychological symptoms of children of divorce. The interactions of two dimensions of self-regulation (task orientation and approach-flexibility) and two dimensions of coping (active and avoidant) predicting children's postdivorce symptoms were tested using a sample of 199 divorced mothers and their children, ages 8 to 12. The approach-flexibility dimension moderated the relations of both active and avoidant coping with children's self-report of anxiety. At higher levels of approach-flexibility, active coping was negatively related to anxiety, while at lower levels of approach-flexibility, active coping was unrelated to anxiety. Avoidant coping was un-related to anxiety at higher levels of approach-flexibility, whereas at lower levels of approach-flexibility, avoidant coping was positively related to anxiety. The task orientation dimension did not interact with coping, but had direct, independent effects on children's self-report of conduct problems, depression, and parent-report of internalizing and externalizing behavior problems. The implications for understanding children's coping with divorce and future directions for research are discussed.Support for this research was provided by NIMH Grants P50-MH39246 to support a Preventive Intervention Research Center at Arizona State University and 5-T32-MH18387 for Post- and Pre-doctoral Training in Prevention Research at Arizona State University.

Individual Differences in the Development of Self-Regulation During Pre-adolescence: Connections to Context and Adjustment

Difficulties with self-regulation are implicated in the development of emotional and behavioral problems during adolescence. Although children’s ability to regulate their behaviors continues to improve throughout childhood and adolescence, it remains unclear how contextual risk factors might influence this development during the transition to adolescence, or how variation in the development of self-regulation predicts adjustment. Using a community sample of 214 8–12 year-olds (T1 M?=?9.5, SD?=?1.01), we examined growth trajectories of effortful control and impulsivity over three years and tested predictors and outcomes of these trajectories. Although predictors of initial levels of self-regulation were largely equivalent for both effortful control and impulsivity, contextual risk factors were related to variations in the development of impulsivity but not effortful control. However, increases in effortful control, but not impulsivity, were associated with level and rate of change in adjustment problems and positive adjustment, suggesting that different dimensions of self-regulation have different antecedents and outcomes in pre-adolescence and adolescence.     

Does monocular visual space contain planes?

The issue of the existence of planes—understood as the carriers of a nexus of straight lines—in the monocular visual space of a stationary human observer has never been addressed. The most recent empirical data apply to binocular visual space and date from the 1960s (Foley, 1964). This appears to be both the first and the last time this basic issue was addressed empirically. Yet the question is of considerable conceptual interest. Here we report on a direct empirical test of the existence of planes in monocular visual space for a group of sixteen experienced observers. For the majority of these observers monocular visual space lacks a projective structure, albeit in qualitatively different ways. This greatly reduces the set of viable geometrical models. For example, it rules out all the classical homogeneous spaces (the Cayley-Klein geometries) such as the familiar Luneburg model. The qualitatively different behavior of experienced observers implies that the generic population might well be inhomogeneous with respect to the structure of visual space.     

Blockade of nucleus basalis magnocellularis or activation of insular cortex histamine receptors disrupts formation but not retrieval of aversive taste memory

Recent research, using several experimental models, demonstrated that the histaminergic system is clearly involved in memory formation. This evidence suggested that during different associative learning tasks, histamine receptor subtypes have opposite functions, related to the regulation of cortical cholinergic activity. Given that cortical cholinergic activity and nucleus basalis magnocellularis (NBM) integrity are needed during taste memory formation, the aim of this study was to determine the role of histamine receptors during conditioned taste aversion (CTA). We evaluated the effects of bilateral infusions of 0.5 μl of pyrilamine (100 mM), an H₁ receptor antagonist, into the NBM, or of R-α-methylhistamine (RAMH) (10 mM), an H₃ receptor agonist, into the insular cortex of male Sprague-Dawley rats 20 min before acquisition and/or retrieval of conditioned taste aversion. The results showed that blockade of H₁ receptors in NBM or activation of H₃ receptors in the insular cortex impairs formation but not retrieval of aversive taste memory. These results demonstrated differential roles for histamine receptors in two important areas for taste memory formation and suggest that these effects could be related with the cortical cholinergic activity modulation during CTA acquisition.     

From Kanizsa Back to Benussi: Varieties of Intentional Reference

The essay analyses the mereological structure of an act of intentional presentation, on the basis of Benussi' and Kanizsa's works. Several aspects are discussed, among which: The existence of diverse formats of representation, their eventual continuity, the presence of subjective integrations at primary levels, and the identification of phrases in the phenomenic structure of an act of presentation. It is argued that the difference between perceptual and mental presence, as elaborated by Kanizsa, proves to be a valid instrument for the categorial analysis of phenomenic appearances.     

Comparison of grasping movements made by healthy subjects in a 3-dimensional immersive virtual versus physical environment

Virtual reality (VR) technology is being used with increasing frequency as a training medium for motor rehabilitation. However, before addressing training effectiveness in virtual environments (VEs), it is necessary to identify if movements made in such environments are kinematically similar to those made in physical environments (PEs) and the effect of provision of haptic feedback on these movement patterns. These questions are important since reach-to-grasp movements may be inaccurate when visual or haptic feedback is altered or absent. Our goal was to compare kinematics of reaching and grasping movements to three objects performed in an immersive three-dimensional (3D) VE with haptic feedback (cyberglove/grasp system) viewed through a head-mounted display to those made in an equivalent physical environment (PE). We also compared movements in PE made with and without wearing the cyberglove/grasp haptic feedback system. Ten healthy subjects (8 women, 62.1 ± 8.8 years) reached and grasped objects requiring 3 different grasp types (can, diameter 65.6 mm, cylindrical grasp; screwdriver, diameter 31.6 mm, power grasp; pen, diameter 7.5 mm, precision grasp) in PE and visually similar virtual objects in VE. Temporal and spatial arm and trunk kinematics were analyzed. Movements were slower and grip apertures were wider when wearing the glove in both the PE and the VE compared to movements made in the PE without the glove. When wearing the glove, subjects used similar reaching trajectories in both environments, preserved the coordination between reaching and grasping and scaled grip aperture to object size for the larger object (cylindrical grasp). However, in VE compared to PE, movements were slower and had longer deceleration times, elbow extension was greater when reaching to the smallest object and apertures were wider for the power and precision grip tasks. Overall, the differences in spatial and temporal kinematics of movements between environments were greater than those due only to wearing the cyberglove/grasp system. Differences in movement kinematics due to the viewing environment were likely due to a lack of prior experience with the virtual environment, an uncertainty of object location and the restricted field-of-view when wearing the head-mounted display. The results can be used to inform the design and disposition of objects within 3D VEs for the study of the control of prehension and for upper limb rehabilitation.     

An Exploratory Evaluation of the Family Meal Intervention for Adolescent Anorexia Nervosa

Although weight restoration is a crucial factor in the recovery of anorexia nervosa (AN), there is scarce evidence regarding which components of treatment promote it. In this paper, the author reports on an effort to utilize research methods in her own practice, with the goal of evaluating if the family meal intervention (FMI) had a positive effect on increasing weight gain or on improving other general outcome measures. Twenty‐three AN adolescents aged 12–20 years were randomly assigned to two forms of outpatient family therapy (with [FTFM] and without [FT]) using the FMI, and treated for a 6‐month duration. Their outcome was compared at the end of treatment (EOT) and at a 6‐month posttreatment follow‐up (FU). The main outcome measure was weight recovery; secondary outcome measures were the Morgan Russell Global Assessment Schedule (MRHAS), amenorrhea, general psychological symptoms, and eating disorder symptoms. The majority of the patients in both groups improved significantly at EOT, and these changes were sustained through FU. Given its primarily clinical nature, findings of this investigation project preclude any conclusion. Although the FMI did not appear to convey specific benefits in causing weight gain, clinical observation suggests the value of a flexible stance in implementation of the FMI for the severely undernourished patient with greater psychopathology.
