How Do Children Restrict Their Linguistic Generalizations? An (Un‐)Grammaticality Judgment Study

A paradox at the heart of language acquisition research is that, to achieve adult‐like competence, children must acquire the ability to generalize verbs into non‐attested structures, while avoiding utterances that are deemed ungrammatical by native speakers. For example, children must learn that, to denote the reversal of an action, un‐ can be added to many verbs, but not all (e.g., roll/unroll; close/*unclose). This study compared theoretical accounts of how this is done. Children aged 5–6 (N = 18), 9–10 (N = 18), and adults (N = 18) rated the acceptability of un‐ prefixed forms of 48 verbs (and, as a control, bare forms). Across verbs, a negative correlation was observed between the acceptability of ungrammatical un‐ prefixed forms (e.g., *unclose) and the frequency of (a) the bare form and (b) alternative forms (e.g., open), supporting the entrenchment and pre‐emption hypotheses, respectively. Independent ratings of the extent to which verbs instantiate the semantic properties characteristic of a hypothesized semantic cryptotype for un‐ prefixation were a significant positive predictor of acceptability, for all age groups. The relative importance of each factor differed for attested and unattested un‐ forms and also varied with age. The findings are interpreted in the context of a new hybrid account designed to incorporate the three factors of entrenchment, pre‐emption, and verb semantics.     

How Do Parents React When Their Children Leave Home? An Integrative Review

The empty nest, which refers to the phase of the family life cycle following the departure of children, has been associated with both positive and negative consequences for parents. This article aims to achieve a better understanding of the complex effects of this transition. It discusses available data and theoretical perspectives on the empty nest, from pioneering works until the most recent studies on the subject. It includes a discussion of conceptualization and methodological issues, as well as a review of determinants of nest leaving. The influence of the departure of children on their parents’ marital quality and psychological well-being, including the potential development of empty-nest syndrome, are then summarized. Studies examining other parental outcome, such as marital instability or relationships with adult children, are also reviewed. It ends with a discussion on boomerang kids and directions for future research. In particular, the need to study the empty-nest period with parents living in a variety of marital situations is acknowledged.     

A Preliminary Study of ADHD Symptoms and Correlates: Do Abused Children Differ from Nonabused Children?

In this pilot study, differences in inattention, impulsivity, and hyperactivity as well as demographic factors were investigated in a community sample of 8- through 11-year-olds, approximately half of whom had experienced child abuse or neglect. Parents completed the Attention Deficit Hyperactivity Disorder Test, the SNAP-IV, the Brief Betrayal Trauma Survey – Parent version, and additional questions. Abused children had more severe impulsivity and inattention, but not hyperactivity, symptoms. Abused boys and girls had a similar age of onset of symptoms, whereas nonabused girls had a much later age of onset than nonabused boys. ADHD is a significant problem among maltreated children. These data support large scale studies investigating possible differences in etiology, presentation, and treatment.

The Positive Illusory Bias: Do Inflated Self-Perceptions in Children with ADHD Generalize to Perceptions of Others?

This study examined whether children with symptoms of attention-deficit/hyperactivity disorder (ADHD) demonstrate positive illusory perceptions of their own competence and others' competence. Participants (67 children with ADHD symptoms; 40 non-ADHD children) completed the Self-Perception Profile for Children and rated actors' competence in videos clips where inconsistent cues of performance had to be integrated in order to determine the actor's competence. Teachers completed the Teacher Rating Scale of Child's Actual Behavior. Children with ADHD symptoms overestimated their own competence relative to teachers' estimates in all domains significantly more than non-ADHD children. There were no significant group differences in perceptions of others' competence. Findings suggest that positive illusions are exclusive to perceptions of self and do not extend to perceptions of others.     

Do Functional Behavioral Assessments Improve Intervention Effectiveness for Students Diagnosed with ADHD? A Single-Subject Meta-Analysis

The primary purpose of this quantitative synthesis of single-subject research was to investigate the relative effectiveness of function-based and non-function-based behavioral interventions for students diagnosed with attention-deficit/hyperactivity disorder. In addition, associations between various participant, assessment, and intervention characteristics were investigated. Eighty-two studies incorporating a total of 168 participants were included. Because no single effect size metric has garnered absolute support to date, three different effect size metrics were calculated: the standard mean difference, percent exceeding the median baseline phase, and improvement rate difference. Overall, function-based interventions were associated with significantly larger effects than non-function-based interventions. Interventions based on the functional analysis manipulations were also associated with larger effects. Limitations, directions for future research, and implications for practice are discussed.     

Do Employees Know How Their Supervisors View Them? A Study Examining Metaperceptions of Job Performance

This study investigated employees’ views about how their supervisors would rate their job performance (i.e., employees’ metaperceptions). Two hundred forty employees from a high-tech firm provided self- and metaperception job performance ratings, and their supervisors also provided ratings of the employees’ performance. The study produced several notable findings, including that metaperceptions were more strongly related to supervisory ratings than were self-ratings, that meta-accuracy was stronger for task versus contextual performance, and that employees who engaged in more impression management behavior exhibited higher meta-accuracy. Discussion focuses on the theoretical and practical implications of these findings.     

How Do Mothers Help Their Children Sleep at Night? Night‐waking Strategy Use Among Mothers of Preschool‐aged Children

Night‐waking is common among preschool‐aged children. Little is known about night‐time parenting among parents of preschool‐aged children. To explore night‐waking strategy use in a community sample, 203 mothers (M age = 32 years, SD = 5.1; children's M age = 3.4 years, SD = 1.0) completed the Night‐waking Strategy Scale (NSS) and measures of general parenting, agreement with night‐waking strategies, and children's sleep. Children were grouped by age (2‐, 3‐, and 4‐to‐5‐year‐olds). Mothers endorsed using routines most frequently, followed by active comforting and rewards; limit‐setting and punishment were used less often. NSS punishment and routines were significantly associated with parenting (e.g. laxness was correlated with NSS routines, rs = ?.35 to .47, p < .001). Night‐waking strategy use was correlated with agreement with those strategies (e.g. active comforting was correlated with agreement with active comforting rs = .35 to .52, p < .001). Active comforting was correlated with the frequency of children's night‐waking for 2‐ and 3‐year‐olds (rs = .35 and .38, respectively, p < .01). Mothers of preschool‐aged children in the community engage in a range of parenting strategies to manage children's night‐waking. These strategies are largely consistent with general parenting and agreement with night‐waking strategy use. Copyright © 2014 John Wiley & Sons, Ltd.     

Do Applicants Fake Their Personality Questionnaire Responses and How Successful are Their Attempts? A Case of Military Pilot Cadet Selection

This paper presents the results of three interrelated studies investigating the occurrence of response distortion on personality questionnaires within selection and the success of applicants in faking situations. In Study 1, comparison of the Big Five personality scores obtained from applicants in a military pilot cadet selection procedure with participants responding honestly, faking good, and faking an ideal candidate revealed that applicants responded more desirable than participants responding honestly but less desirable than respondents under fake instructions. The occurrence of faking within the military pilot selection process was replicated in Study 2 using the Eysenck Personality Questionnaire and another comparison group. Finally, in Study 3, comparison of personality profiles obtained in selection and ‘fake job’ situations with experts' estimates indicated that participants were partially successful in faking the desirable profile.     

Deficit in Response Inhibition in Children with Attention Deficit/Hyperactivity Disorder (ADHD): Impact of Motivation?

To date, neuropsychological and psycho-physiological studies have revealed inconsistent results regarding an executive or motivational deficit explaining the response inhibition deficit in children with attention deficit/hyperactivity disorder (ADHD). Research on differentiating neuropsychological processes in ADHD subtypes is still scarce. Therefore, the motivational impact on response inhibition among boys with ADHD was examined in this study. In the first study, 19 boys with ADHD-combined type (ADHD-C) and 19 age-matched healthy control subjects performed a modified Go/No-Go task with the following experimental conditions: neutral, auditory feedback, reward, response cost, and reward/response cost. Performance and physiological data (heart rate and skin conductance responses) were recorded. In a second study with the modified Go/No-Go task, data for six children with ADHD-C, six with ADHD-inattentive subtype (ADHD-I), and six healthy control subjects were compared. Neither of the two studies revealed group by condition interactions. In study 1, boys with ADHD-C generally made more commissions and omissions compared to the control group. However, feedback significantly improved the response inhibition in all children. The heart rate of all children was increased in the two conditions of reward and reward/response cost. Study 2 revealed that children with ADHD-I responded more slowly and showed increased reaction time variability compared to both other groups. The present study supports an executive rather than a motivational deficit in the response inhibition among children with ADHD-C, though further results also indicate the role of auditory feedback on response inhibition. Additionally, the findings support the differentiation of ADHD-C and ADHD-I, suggesting that ADHD-I children are characterized by a sluggish cognitive tempo.     

The (Mis)understanding of Scientific Uncertainty? How Experts View Policy-Makers,the Media and Publics

Abstract

Frequent claims that publics ‘misunderstand’ science ignore the contested definition of scientific uncertainty itself. Scientific uncertainty means different things in the natural sciences, social sciences and the humanities, while public controversies show that interpretations of scientific uncertainty have different implications for policy and decision-making. This prompts analysis of the ways that experts view scientific uncertainty and how they characterise the (mis)understandings of this uncertainty by policy-makers, media and publics. Experts from diverse academic fields define scientific uncertainty differently depending on their disciplinary background. For example, mathematics provides experts from the natural sciences with a practice language that facilitates communication with those sharing this cultural competence, but it does not suffice for engaging with wider audiences. Further, experts’ views of diverse publics come across as folk theories, in Arie Rip's terms, which, compiled from disparate pieces of information, can be used to fill a gap in the knowledge about publics.     

How Do Family-Focused Prevention Programs Work? A Review of Mediating Mechanisms Associated with Reductions in Youth Antisocial Behaviors

The development and evaluation of family-focused preventive interventions has grown significantly in recent decades, but the degree to which these interventions produce anticipated improvements in the family environment, and the extent to which such changes are associated with reductions in youth antisocial behaviors (ASB), is unclear. This article seeks to answer these questions by reviewing evidence from tests of mediation conducted in evaluations of family-focused interventions. Interventions are drawn from family-focused interventions rated as Model Plus, Model, or Promising on the Blueprints for Healthy Youth Development Web site (http://www.colorado.edu/cspv/blueprints/) based on evidence of their effectiveness in reducing child externalizing behaviors, substance use, and/or delinquency. Of the 19 such interventions listed on Blueprints, seven programs (37 %) were evaluated using mediation analyses which met study criteria. Two-thirds (67 %) of these analyses indicated significant improvements in the targeted family processes for intervention versus control group participants. Over half (62 %) of all tests of mediation were statistically significant and indicated that improvements in the family environment were associated with reductions in ASB. The results support prior theoretical and empirical literature identifying the family as an important context for preventing ASB and promoting healthy youth development. The findings also provide information that can be used to refine current family-focused interventions in order to increase their efficiency and potency, and to develop new interventions in order to expand the number and types of families who can benefit from such services.     

(Re)Conceptualizing Sleep Among Children with Anxiety Disorders: Where to Next?

Children with anxiety disorders (AD) characteristically complain of sleep problems and the extent to which cognitive behavioral treatments (CBT) for childhood anxiety produce sleep-based improvements is a topic of increasing interest. The current paper reviews available evidence for subjective sleep complaints and objective sleep alterations in children and adolescents with AD, including investigations of potential changes in sleep following anxiety-focused CBT. Despite pervasive complaints of poor sleep, the empirical literature provides minimal evidence for actual sleep–wake alterations in this population of youth and evidence for sleep-based changes following treatment for anxiety is minimal. In line with calls for more comprehensive models of the role of sleep in developmental psychopathology, several fundamental gaps in understanding are described and highlighted as essential avenues for clarifying the nature and consequences of poor quality sleep among youth with clinical levels of anxiety. In a second section of the paper, an emerging body of novel, translational research investigating more intricate sleep–anxiety relationships is introduced with potential implications for both etiological models and treatment design and delivery.     

Can the Family Assessment Device (FAD) Be Used with School Aged Children?

This article examines the usefulness of the Family Assessment Device(FAD) in assessing family functioning with school-aged children (under 12 years of age) compared to children 12 and older and mothers. FAD reports from 194 children with asthma (132 under 12 years; 62 12 years and older) were evaluated in comparison to mothers' FAD reports as well as mothers' reports on two other family functioning measures: the Family Inventory of Life Events (FILE) and the Impact on Family (IOF) scale, both relevant to functioning in families with children with asthma. Although FAD scale reliabilities were lowest in younger children (alpha = 48-.79), good concurrent validity was found with mothers' reports on the three different measures of family functioning. Older childrens' FAD scales showed good reliability (> .70) but poorer agreement with the various maternal measures. With modifications to make items more structured and simplified, the FAD could be tried with younger children, although documentation of improved reliability is needed before more widespread use with school-aged children is advocated. The measure already shows good agreement with maternal report in this younger age group, which likely would be strengthened with improved reliability. FAD reports in older children correlated less well with maternal measures, but may represent nonredundant information on family health from an independent perspective and are worth considering in addition to mothers' perspectives.     

Do infants understand simple arithmetic? A replication of Wynn (1992)

Numerical competence in 5-month-old infants is investigated using a violation-of-expectation paradigm. An experiment is reported which replicates the findings of Wynn (1992). In additional conditions, 5-month-olds are shown to be sensitive to impossible outcomes following addition or subtraction operations on small sets of objects, regardless of identity changes. Results support Wynn's interpretation that infants' responses are based on arithmetical ability. An alternative explanation, that infants' responses are based on their knowledge of the principles of physical object behavior, is also discussed.     

Hyperactivity in Boys with Attention-Deficit/Hyperactivity Disorder (ADHD): A Ubiquitous Core Symptom or Manifestation of Working Memory Deficits?

Hyperactivity is currently considered a core and ubiquitous feature of attention-deficit/hyperactivity disorder (ADHD); however, an alternative model challenges this premise and hypothesizes a functional relationship between working memory (WM) and activity level. The current study investigated whether children’s activity level is functionally related to WM demands associated with the domain-general central executive and subsidiary storage/rehearsal components using tasks based on Baddeley’s (Working memory, thought, and action. New York: Oxford University Press 2007) WM model. Activity level was objectively measured 16 times per second using wrist- and ankle-worn actigraphs while 23 boys between 8 and 12 years of age completed control tasks and visuospatial/phonological WM tasks of increasing memory demands. All children exhibited significantly higher activity rates under all WM relative to control conditions, and children with ADHD (n = 12) moved significantly more than typically developing children (n = 11) under all conditions. Activity level in all children was associated with central executive but not storage/rehearsal functioning, and higher activity rates exhibited by children with ADHD under control conditions were fully attenuated by removing variance directly related to central executive processes.

Competing Core Processes in Attention-Deficit/Hyperactivity Disorder (ADHD): Do Working Memory Deficiencies Underlie Behavioral Inhibition Deficits?

The current study examined competing predictions of the working memory and behavioral inhibition models of ADHD. Behavioral inhibition was measured using a conventional stop-signal task, and central executive, phonological, and visuospatial working memory components (Baddeley 2007) were assessed in 14 children with ADHD and 13 typically developing (TD) children. Bootstrapped mediation analyses revealed that the visuospatial working memory system and central executive both mediated the relationship between group membership (ADHD, TD) and stop-signal task performance. Conversely, stop-signal task performance mediated the relationship between group membership and central executive processes, but was unable to account for the phonological and visuospatial storage/rehearsal deficits consistently found in children with ADHD. Comparison of effect size estimates for both models suggested that working memory deficits may underlie impaired stop-signal task performance in children with ADHD. The current findings therefore challenge existing models of ADHD that describe behavioral inhibition as a core deficit of the disorder.
