Reduced automatic motivational orientation towards food in restricting anorexia nervosa

A striking and characteristic feature of the restricting subtype of anorexia nervosa (AN) is that they are extremely successful in regulating their food intake in a destructive manner. A possible explanation for the persistent character of their restricted food intake could be a loss of the motivational saliency of food in restricting AN patients. The present study aimed to investigate motivational orientation for food in the restricting subtype of anorexia nervosa with an indirect performance-based measure and a self-report measure of craving. An indirect approach avoidance task was administered to measure automatic approach tendencies for high-fat and low-fat food in restricting adolescent AN-like patients (n=89) and a group of healthy adolescents (n=76). As predicted, restricting AN-like patients showed less automatic motivational orientation toward food than healthy controls. In a similar vein, AN-like patients reported less craving for food than the group of healthy controls. The loss of an automatic motivational orientation toward food together with the deliberate strategy to avoid food might help explain the ability of restricting AN-like patients to regulate their food intake.     

The relationship of parental warm responsiveness and negativity to emerging behavior problems following traumatic brain injury in young children

Parenting behaviors play a critical role in the child's behavioral development, particularly for children with neurological deficits. This study examined the relationship of parental warm responsiveness and negativity to changes in behavior following traumatic brain injury (TBI) in young children relative to an age-matched cohort of children with orthopedic injuries (OI). It was hypothesized that responsive parenting would buffer the adverse effects of TBI on child behavior, whereas parental negativity would exacerbate these effects. Children, ages 3-7 years, hospitalized for TBI (n = 80) or OI (n = 113), were seen acutely and again 6 months later. Parent-child dyads were videotaped during free play. Parents completed behavior ratings (Child Behavior Checklist; T. M. Achenbach & L. A. Rescorla, 2001) at both visits, with baseline ratings reflecting preinjury behavior. Hypotheses were tested using multiple regression, with preinjury behavior ratings, race, income, child IQ, family functioning, and acute parental distress serving as covariates. Parental responsiveness and negativity had stronger associations with emerging externalizing behaviors and attention-deficit/hyperactivity disorder symptoms among children with severe TBI. Findings suggest that parenting quality may facilitate or impede behavioral recovery following early TBI. Interventions that increase positive parenting may partially ameliorate emerging behavior problems.     

Effects of Kindermusik training on infants’ rhythmic enculturation

Phillips‐Silver and Trainor (2005) demonstrated a link between movement and the metrical interpretation of rhythm patterns in 7‐month‐old infants. Infants bounced on every second beat of a rhythmic pattern with no auditory accents later preferred to listen to an accented version of the pattern with accents every second beat (duple or march meter), whereas infants bounced on every third beat of the same rhythmic pattern preferred to listen to a version with accents every third beat (triple or waltz meter). The present study compared infants participating in Kindermusik classes with infants not participating in music classes. In Kindermusik classes infants receive enriched experience moving to music. Following Western musical norms, the majority of the music samples in the classes are in duple meter. During the preference test, Kindermusik infants listened longer overall, indicating heightened interest in musical rhythms. Both groups listened longer to the accented version that matched how they had been bounced, but only the Kindermusik group showed a stronger preference in the case of duple bouncing than in the case of triple bouncing. We conclude that musical classes for infants can accelerate the development of culture‐specific metrical perception.     

Theory of mind skills 1 year after traumatic brain injury in 6- to 8-year-old children

This study examined the longer-term effects of traumatic brain injury (TBI) on theory of mind (ToM) skills of children who were between the ages of 5 and 7 years at the time of injury. Fifty-two children with orthopaedic injury, 30 children with moderate TBI, and 12 children with severe TBI were evaluated approximately 1 year post-injury (mean age=6.98 years, SD=0.59, range=6.02–8.26). Children with severe TBI did not engage in representation of first- and second-order mental states at a developmental level comparable to their peers, suggesting stagnation or lack of development, as well as regression of putatively existing ToM skills. Age, task-specific cognitive demands, and verbal abilities were strong predictors of ToM performance. However, even after taking those factors into account, children with severe TBI had poorer ToM performance than children with orthopaedic injuries.     

Beyond the Class Norm: Bullying Behavior of Popular Adolescents and its Relation to Peer Acceptance and Rejection

This study examined to what extent bullying behavior of popular adolescents is responsible for whether bullying is more or less likely to be accepted or rejected by peers (popularity-norm effect) rather than the behavior of all peers (class norm). Specifically, the mean level of bullying by the whole class (class norm) was split into behavior of popular adolescents (popularity-norm) and behavior of non-popular adolescents (non-popularity-norm), and examined in its interaction with individual bullying on peer acceptance and peer rejection. The data stem from a peer-nominations subsample of TRAILS, a large population-based sample of adolescent boys and girls (N = 3312). The findings of multilevel regression analyses demonstrated that the negative impact of individual bullying on peer acceptance and the positive impact on peer rejection were particularly weakened by bullying by popular adolescents. These results place the class-norm effects found in previous person-group dissimilarity studies in a different light, suggesting that particularly bullying by popular adolescents is related to the social status attached to bullying.

Confounds in pictorial sets: The role of complexity and familiarity in basic-level picture processing

Complexity is conventionally defined as the level of detail or intricacy contained within a picture. The study of complexity has received relatively little attention-in part, because of the absence of an acceptable metric. Traditionally, normative ratings of complexity have been based on human judgments. However, this study demonstrates that published norms for visual complexity are biased. Familiarity and learning influence the subjective complexity scores for nonsense shapes, with a significant training x familiarity interaction [F(1,52) = 17.53, p < .05]. Several image-processing techniques were explored as alternative measures of picture and image complexity. A perimeter detection measure correlates strongly with human judgments of the complexity of line drawings of real-world objects and nonsense shapes and captures some of the processes important in judgments of subjective complexity, while removing the bias due to familiarity effects.     

Discourse-mediation of the mapping between language and the visual world: Eye movements and mental representation

Two experiments explored the mapping between language and mental representations of visual scenes. In both experiments, participants viewed, for example, a scene depicting a woman, a wine glass and bottle on the floor, an empty table, and various other objects. In Experiment 1, participants concurrently heard either ‘The woman will put the glass on the table’ or ‘The woman is too lazy to put the glass on the table’. Subsequently, with the scene unchanged, participants heard that the woman ‘will pick up the bottle, and pour the wine carefully into the glass.’ Experiment 2 was identical except that the scene was removed before the onset of the spoken language. In both cases, eye movements after ‘pour’ (anticipating the glass) and at ‘glass’ reflected the language-determined position of the glass, as either on the floor, or moved onto the table, even though the concurrent (Experiment 1) or prior (Experiment 2) scene showed the glass in its unmoved position on the floor. Language-mediated eye movements thus reflect the real-time mapping of language onto dynamically updateable event-based representations of concurrently or previously seen objects (and their locations).     

Being Admired or Being Liked: Classroom Social Status and Depressive Problems in Early Adolescent Girls and Boys

This study investigates associations between depressive problems and classroom social status in a large population cohort of Dutch early adolescents (N = 1046, age 13.52 +/- 0.51, 52.4% girls). Depressive problems were assessed by parent and self-reports and classroom status by peer nominations. We assessed peer status with respect to both achievement-related (being a good learner, being good at sports, being good-looking) and affection-related (being liked, being disliked, being best friend) areas. In boys, depressive problems were most strongly associated with not being good at sports, while in girls the association was strongest for not being liked. The risk of a low status in one area could largely be compensated by a high status in another area.     

The Grossarth-Maticek and Eysenck Personality Types,Health-related behaviour,and indicators of transitory ill-health

The aim of this study was to scrutinize the relationship between personality type as described by Grossarth-Maticek and Eysenck, health-related behaviours, and indicators of transitory ill health in a community sample. The sample consisted of all per sons aged 40 years (45 men and 35 women) in a Swedish municipality who agreed to take part in a health examination at the primary health care centre of the municipality. The Short Interpersonal Reactions Inventory (Grossarth-Maticek and Eysenck, 1990) was used to measure personality type. Self-report data were obtained regarding seven health-related behaviours. Health was assessed in three ways; self-report (paper and pencil), self-report (interview response to physician), and measures of 36 biological variables including immune system indicators. The allocation of persons to the different personality types proved problematic using the established methods. By combining the types, according to Eysenck's personality model, and performing a cluster analysis on this combination, a ‘healthy’ and a ‘stressed’ profile were identified within both the male and the female group of subjects. Persons in the healthy personality cluster showed more favourable scores on the health-related behaviour indices and on the self-report health scales than the persons in the stressed cluster. They also tended to score lower than those in the stressed cluster on most of the biological markers known to increase during acute stress. The possibility that this implies a higher level of strain for the persons in the stressed cluster on various bodily systems is discussed.
