Inversion of subject NP and aux in children's questions

Bellugi has proposed a stage of language acquisition in which children invert subject NP and Aux in yes-no but notwh questions. It was proposed that this stage would be found in a sampling of questions from young children. Cross-sectional samples of questions were collected from young children between 20 and 311. The results did not bear out this expectation. Based on percentages of inversion, none showed this stage. The results are discussed in terms of the importance of frequency in determining stages of acquisition and the use of children's data as psychological evidence for linguistic rules.     

The asymptotic distribution of commonality components

Commonality components have been defined as a method of partitioning squared multiple correlations. In this paper, the asymptotic joint distribution of all 2 ^k – 1 squared multiple correlations is derived. The asymptotic joint distribution of linear combinations of squared multiple correlations is obtained as a corollary. In particular, the asymptotic joint distribution of commonality components are derived as a special case. Simultaneous and nonsimultaneous asymptotic confidence intervals for commonality components can be obtained from this distribution.This work was supported in part by the Spencer Foundation and the National Science Foundation.The authors are grateful to Bryna Siegel-Gorlick for her help in obtaining the data used in Example 4.3, and to the referees for their comments and suggestions.     

Very long-term retention of a novel

This study investigated the very long-term retention of a full-length novel originally studied as part of a university undergraduate course. One hundred and forty former students completed three tests designed to assess retention of Charles Dickens' Hard Times. Retention intervals ranged from 3 to 39 months. Subjects' responses when they were asked to report their most vivid and enduring memory of the novel were consistent with story grammar models which claim that components of a story which are higher in a hierarchy are remembered better than those lower in the hierarchy. A free recall test of the names and roles of the characters in the novel found that retention of both declined rapidly in the first few months following acquisition, that names were forgotten more quickly than roles, and that retention of both had stabilized above baseline before the longest retention interval. These data are interpreted in terms of a schema account of memory retention, in which retention of schematic knowledge (roles), but not non-schematic knowledge (names) can be mediated by abstract knowledge structures. The results of a fact verification test showed that memory for events of high importance in the novel was better than memory for events of low importance, consistent with models that suggest that texts and stories are represented hierarchically in memory. Confidence ratings also declined over time and showed that subjects generally assessed the accuracy of their responses correctly. The significant predictors of memory for the novel were retention interval and the mark obtained on a coursework essay on Hard Times.     

A comparison of fixed momentary differential reinforcement of other behavior to variable momentary differential reinforcement of other behavior to reduce challenging behavior

Differential reinforcement of other behavior (DRO) is commonly used to reduce behavioral excesses. Momentary DRO schedules involve delivery of reinforcement contingent upon the absence of the target behavior at a given moment. Two variations of momentary DRO exist: fixed-momentary (FM) DRO and variable-momentary (VM) DRO. In the current study, we directly compared FM-DRO and VM-DRO schedules to reduce challenging behavior maintained by automatic reinforcement exhibited by four children with autism spectrum disorder. The results suggest that both the DRO schedules were equally effective to reduce challenging behavior. A social validity measure showed that most caregivers rated the VM-DRO as a preferred schedule and noted the potential for FM-DRO schedule to become more discriminable over time, which could reduce its effectiveness. However, most caregivers also commented that the FM-DRO schedule was easier to implement.     

Parenting typologies in Georgian and Belgian adolescents: Associations with self-esteem

The parenting context is of fundamental importance for the optimal development of adolescents. Making use of a person-centered approach, we derived parenting typologies from the perspective of Georgian and Belgian adolescents based on four dimensions of perceived parenting (responsiveness, structure, psychological control, and autonomy support). Further, we examined how perceived parenting typologies were associated with adolescents' self-esteem. The study sample included 511 Georgian and 830 Belgian adolescents (N = 1341; 48% female). A cluster-analytic procedure on the full sample was conducted separately for mothers and fathers. The analysis yielded five parenting typologies: Supportive—Highly structuring (high responsiveness and structure), Highly structuring—Moderately controlling (high structure and psychological control, moderate—responsiveness), Supportive—Low structuring/controlling (high responsiveness and autonomy support, low structure and psychological control), Highly controlling (very high psychological control, low responsiveness and autonomy support) and Uninvolved (low on all dimensions). Results indicated that the Highly structuring—Moderately controlling paternal cluster was more prevalent in the Belgian sample. A country-moderating effect was found with the paternal Uninvolved profile associated with low levels of self-esteem in Belgian adolescents, but with moderate levels of self-esteem in Georgian adolescents.     

Does partisan media make a pawn of mistrust? Institutional trust and preventive COVID-19 health behaviors in a polarized pandemic

In a rapidly developing crisis such as the COVID-19 pandemic, people are often faced with contradictory or changing information and must determine what sources to trust. Across five time points (N = 5902) we examine how trust in various sources predicts COVID-19 health behaviors. Trust in experts and national news predicted more engagement with most health behaviors from April 2020 to March 2022 and trust in Fox news, which often positioned itself as counter to the mainstream on COVID-19, predicted less engagement. However, we also examined a particular public health behavior (masking) before and after the CDC announcement recommending masks on 3 April 2020 (which reversed earlier expert advice discouraging masks for the general public). Prior to the announcement, trust in experts predicted less mask-wearing while trust in Fox News predicted more. These relationships disappeared in the next 4 days following the announcement and reversed in the 2 years that follow, and emerged for vaccination in the later time points. We also examine how the media trusted by Democrats and Republicans predicts trust in experts and in turn health behaviors. Broadly we consider how the increasingly fragmented epistemic environment has implications for polarization on matters of public health.     

The Shattering of the Stimulus Barrier: The Case for an Integrative Approach in Short-Term Treatment of Psychological Trauma

The paper argues that the integrative psychotherapy approach is ideally suited to the treatment of psychological trauma. A brief term intervention model, devised by psychotherapists working with trauma in the South African context, is presented to illustrate this premise. It is asserted that posttraumatic stress represents a disorder in which dysfunction occurs both internally and externally, according to Freud at the interface of these two aspects of psychological functioning, i.e., at the ego boundary. Disturbance manifests in recognizable cognitive, behavioral, and somatic symptoms and in addition carries unconscious associations and anxieties. The ideal approach to treatment thus appears to be to draw on the relative strengths of both the psychodynamic and cognitive-behavioral schools. Existing trauma intervention models reflect the centrality of integration in many respects, although this does not seem to be explicitly recognized. The five components of the model referred to above are outlined and each component is explored in terms of its efficacy within both a cognitive-behavioral and a psychodynamic framework. Illustrative case material is provided to demonstrate the mechanisms at work in each case. The paper argues that the clinical success of the model lies in its integrative perspective and that psychotherapy integration should be recognized as the approach of choice in the treatment of traumatized individuals.     

Homophobic bullying victimization trajectories: The roles of perpetration,sex assigned at birth,and sexuality

There is a paucity of research on developmental trajectories of bias-based aggression. We examined homophobic bullying victimization trajectories among high school students (N = 3,064; M age = 13.67; Girls = 50.2%) and how these developmental pathways vary as a function of factors like homophobic bullying perpetration, sex assigned at birth, and sexuality. Using data from a 3-wave longitudinal investigation over a 2-year period, we utilized latent growth mixture modeling to explore the aforementioned trajectories. Findings suggested that there were three distinct classes characterized by high initial rates and declines over time, low initial rates, and increases over time, and low, stable, rate across time. Furthermore, results indicated that homophobic bullying perpetration, sex assigned at birth, and sexuality all predicted class membership.
