Health Status and Peer Relationships in Early Adolescence: The Role of Peer Contact, Self-esteem, and Social Anxiety

We examined associations between children’s health status and the quality of their peer relationships, as well as factors that may account for individual variation in the quality of chronically ill and healthy children’s peer relationships. Our sample included 268 children (138 boys; 130 girls) with 149 European-Americans and 119 African-Americans. There were 91 children with a chronic illness; 35 with asthma, 26 with diabetes, and 30 with obesity. Chronically ill children were characterized by teachers as displaying less prosocial behavior, less overt aggression, and less relational aggression with peers than healthy children. Chronically ill children reported lower levels of peer contact and higher levels of social anxiety than healthy children. Among chronically ill children those with high self-esteem were more prosocial and less aggressive than those with low self-esteem. Our findings suggest that chronically ill children are at risk for peer relationship difficulties, but that self-esteem may serve as a protective factor against poor peer relationships for some chronically ill children.     

Development and validation of the Maladaptive Daydreaming Scale (MDS)

This study describes the development of the Maladaptive Daydreaming Scale (MDS), a 14-item self-report instrument designed to gauge abnormal fantasizing. Our sample consisted of 447 English-speaking individuals from 45 different countries. A 3-correlated-factors model best presented the underlying dimensions Yearning, Kinesthesia and Impairment, capturing related rewarding experiences as well as psychological impairment of maladaptive daydreaming. MDS scores were associated with obsessive–compulsive behavior and thoughts, dissociative absorption, attention deficit, and high sense of presence during daydreaming, but less with psychotic symptoms. The MDS and its subscale demonstrated good validity, sound internal consistency and temporal stability and discriminated well between self-identified individuals with and without maladaptive daydreaming. Considering the instrument’s high sensitivity and specificity levels, it seems an excellent measure for future investigation of MD that will, hopefully, shed light on the etiology and psycho-biological mechanisms involved in this mental condition, as well as on the development of effective MD treatment methods.     

Do shame and perfectionistic self-presentation explain the link between early affiliative memories and eating psychopathology?

This study tested a model examining the impact that early affiliative memories (both with family and peers) on eating psychopathology, and whether these links are carried by the mechanisms of external shame and body image-related perfectionistic self-presentation, in a sample of 480 female college students. Path analyses’ results revealed that this model accounted for 48% of disordered eating’s variance and suggests that the lack of early positive emotional memories is associated with higher levels of shame (feelings of inferiority and unattractiveness), and with higher tendency to adopt body image-related perfectionistic strategies, that seem to explain excessive eating concern and rigid control of one’s eating behaviors. This study offers important insights for future research and for the development of intervention programs, by revealing the importance of assessing and targeting shame and perfectionistic strategies and suggesting the importance of promoting adaptive emotion regulation strategies.     

Inconsistency effects in source memory and compensatory schema-consistent guessing

The attention–elaboration hypothesis of memory for schematically unexpected information predicts better source memory for unexpected than expected sources. In three source-monitoring experiments, the authors tested the occurrence of an inconsistency effect in source memory. Participants were presented with items that were schematically either very expected or very unexpected for their source. Multinomial processing tree models were used to separate source memory, item memory, and guessing bias. Results show an inconsistency effect in source memory accompanied by a compensatory schema-consistent guessing bias when expectancy strength is high, that is, when items are very expected or very unexpected for their source.     

Better early or late? Examining the influence of age of exposure and language proficiency on executive function in early and late bilinguals

Previous research has shown that early and late bilinguals differ in their language learning experiences and linguistic outcomes. However, evidence of differences between these bilinguals on measures of executive function (EF) has been mixed. As a result, the current study sought to (1) determine whether early and late bilinguals vary from one another and (2) exhibit cognitive advantages in EF relative to monolinguals. One hundred and five participants (42 monolinguals, 40 early bilinguals and 23 late bilinguals) completed the study. Participants' EF skills were assessed using the Auditorily Cued Number Numeral Task. Overall, the results did not reveal clear advantages for the early bilinguals compared to the two other groups. In fact, early bilinguals and monolinguals were equivalent in their performance on the EF task, whereas the late bilinguals were less accurate, relative to the other two groups. The differences in the performance of early and late bilinguals are discussed in terms of the competition model of second-language learning proposed in previous research. Taken together, these findings indicate that individual differences in EF influence the observed differences found in EF across language groups.     

Early mother-infant interaction during breast- and bottle-feeding

Thirty-two primiparous mothers with their neonates, 20 breast-fed and 12 bottle-fed, were videotaped during feeding longitudinally (at 3, 10 days, 1 and 3 months) in order to investigate whether patterns of mother-infant interaction observed during breast- and bottle-feeding differ also for behavior not directly related to sucking. Infant state, sucking behavior, mother behavior and mother-infant interaction were analyzed by both sequential and non sequential analysis. Results suggest that the method of feedings affects mother-infant interaction observed during and just after feeding also for some behavior not directly related to sucking. The percentage of mutual touch, tactile stimulation and mother's gaze to infant was significantly more elevated during breast-feeding. Independently of the feeding mode, significant sequential dependencies between infant state of alertness and auditory stimulation, and auditory stimulation and mutual gaze were found.     

Compulsive exercise or exercise dependence? Clarifying conceptualizations of exercise in the context of eating disorder pathology

ObjectiveMaladaptive exercise relates to eating disorder (ED) pathology and impairment in clinical and non-clinical populations. At present, two different conceptualizations of maladaptive exercise are often studied in relation to ED pathology: compulsive exercise and exercise dependence. Compulsive exercise functions to avoid negative affect (e.g., guilt and anxiety) associated with not exercising, whereas exercise dependence is associated with tolerance to exercise benefits and avoidance of exercise withdrawal. At present, clinicians and researchers struggle to determine the most appropriate term for describing problematic exercise in individuals with ED pathology. This study aimed to directly compare these conceptualizations of maladaptive exercise in relation to severity of ED pathology.DesignThis study examined cross-sectional data.MethodUndergraduate participants (N = 235, 78% female) with elevated ED pathology completed the Eating Disorder Examination Questionnaire (EDE-Q), Compulsive Exercise Test (CET), and Exercise Dependence Scale (EDS). Multiple linear regression analyses evaluated associations between EDE-Q and CET and EDS scores and dominance analysis determined which qualities of exercise were uniquely associated with EDE-Q scores.ResultsResults suggest that compulsive qualities of exercise, including exercise to control shape and weight and to avoid negative affect are more strongly associated with severity of ED pathology than qualities of exercise dependence.ConclusionsClinicians and researchers working with ED populations can benefit from prioritizing assessments that capture compulsive qualities of exercise. Additionally, these results suggest that interventions that effectively target other compulsive behaviors (e.g., exposure and response prevention) may be promising treatment options for problematic exercise in the context of EDs.     

Deception and subtypes of aggression during early childhood

A multi-informant study investigated the association between deception capacities and subtypes of aggression in a young early childhood sample (M = 44.65 months of age, SD = 13.39, N = 64). A newly developed teacher report of deception had appropriate psychometric properties (reliability, concurrent validity, and construct validity). Recently introduced observational methods of physical and relational aggression were reliable and valid with this sample. Findings indicated that both physical and relational aggression were associated with concurrent deception. For boys only, physical aggression uniquely predicted deception, controlling for the variance associated with relational aggression. In addition, relational aggression predicted deception above and beyond the role of physical aggression for the entire sample.     

Early Childhood Externalising Behaviour Problems: Child, Parenting, and Family-related Predictors Over Time

This study examined the dynamic relationships between child, parenting, and family-related predictor variables and early childhood externalising behaviour problems. A community sample of 395 Australian children was followed longitudinally, and assessed at 4 and 6 years with the Child Behavior Checklist, Teacher Report Form, and standard measures of parenting, temperament, and familial adversity. Variables based on the average scores across the two assessments and the change in scores between assessments were utilised as predictors of parent-reported and teacher-reported externalising behaviour problems at age 6. It was hypothesised that both higher average scores and more detrimental changes in scores, would independently predict externalising problems at age 6. Multivariable analyses found that the presence of parent-reported child externalising problems in six-year-olds were predicted by: (i) the presence of parent-reported child externalising problems at age 4, (ii) higher average “teacher-reported child externalising behaviour,” “inflexible temperament,” “non-persistent temperament,” and “over-reactive parenting,” and (iii) an increased “inflexible temperament” score between age 4 and age 6. The presence of teacher-reported child externalising problems at age 6 was predicted by higher average “parent-reported child externalising behaviour,” and “over-reactive parenting.” The results provide further evidence of the adverse impact of continuing high levels of temperament difficulties and over-reactive parenting on externalising behaviour in early childhood. However, contrary to expectations, the contribution of including the dynamic change scores was limited.     

Meaningful processing of meaningless stimuli: the influence of perceptual experience on early visual processing of faces

The N170 is an event-related potential component associated with extrastriate visual mechanisms involved in detecting human faces and leading to their characteristic structural encoding. Consequently the N170 discriminates the processing of stimuli providing physiognomic information from the processing of other, similarly complex, visual patterns. We have used this effect to explore the top-down influence of newly acquired experience on the initial visual categorization of physiognomic stimuli. Schematic faces having the inner components mislocated did not elicit an N170 effect in naive participants. However, after normally configured versions of the schematic faces were exposed, suggesting what the ambiguous patterns represented, the same patterns elicited an N170 effect as conspicuous as that elicited by regular schematic faces. This priming effect, which changed the visual processing of distorted faces in extrastriate regions, could not be explained by post-perceptual decisions. Although accounts based on changes in focal attention, or within-vision constraints could not be categorically rejected, this outcome might suggest cognitive penetrability of early visual categorization.
