Early language processing efficiency predicts later receptive vocabulary outcomes in children born preterm

As rates of prematurity continue to rise, identifying which preterm children are at increased risk for learning disabilities is a public health imperative. Identifying continuities between early and later skills in this vulnerable population can also illuminate fundamental neuropsychological processes that support learning in all children. At 18 months adjusted age, we used socioeconomic status (SES), medical variables, parent-reported vocabulary, scores on the Bayley Scales of Infant and Toddler Development (third edition) language composite, and children’s lexical processing speed in the looking-while-listening (LWL) task as predictor variables in a sample of 30 preterm children. Receptive vocabulary as measured by the Peabody Picture Vocabulary Test (fourth edition) at 36 months was the outcome. Receptive vocabulary was correlated with SES, but uncorrelated with degree of prematurity or a composite of medical risk. Importantly, lexical processing speed was the strongest predictor of receptive vocabulary (r = ?.81), accounting for 30% unique variance. Individual differences in lexical processing efficiency may be able to serve as a marker for information processing skills that are critical for language learning.     

How do students implement collaborative testing in real-world contexts?

Recent research has explored the effects of collaborative testing, showing costs and benefits during learning and for subsequent memory. However, no prior research is informative about whether and how students use collaborative testing in real-world contexts. Accordingly, the primary purpose of the current research was to explore the extent to which students use collaborative testing during self-regulated learning. We conducted three surveys (n = 692 across three samples) asking students about their use of collaborative testing, with a particular interest in conditions under which students report implementing collaborative testing. Among the key outcomes, a majority of students reported using collaborative testing when studying in a group. Additionally, students reported that key term definitions are the material most often used during collaborative testing. Students are also more motivated to use testing and believe testing is more effective and more fun when implemented in a group versus alone. Outcomes also shed light on metacognitive components of collaborative testing, with the student asking (versus answering) the question making the monitoring judgement whereas both students make the control decision about when to terminate practice. We discuss ways in which the collaborative memory literature can be extended to support more successful student learning.     

The Ethical Inclusion of Children With Psychotic Disorders in Research: Recommendations for an Educative,Multimodal Assent Process

This article addresses the issue of properly assenting children with psychotic disorders to participate in clinical research. Due to the protective concerns with such a vulnerable population, additional precautions are necessary to ensure that youth with psychotic disorders assent to research with an appropriate level of understanding regarding study procedures. Current literature suggests that positive/negative symptoms and minor cognitive deficits do not interfere with the ability to comprehend study-related information for adults with psychosis if the study information is presented through an educative process. Similarly, youth benefit from repeated presentation of procedures and periodic assessment of their comprehension. An integrated educative process is proposed that emphasizes the importance of an interactive consent through repetition and participant/investigator feedback.     

The associations between adult attachment,posttraumatic symptoms,and posttraumatic growth

Background and Objectives: Individual differences after trauma vary considerably and can range from posttraumatic stress disorder (PTSD) to posttraumatic growth (PTG). Current theoretical models cannot fully explain this variability. Therefore, we integrated attachment theory with Ehlers and Clark's model of PTSD to understand whether attachment style is associated with negative appraisals of a traumatic event(s), posttraumatic stress symptoms (PTS), and PTG. Our aim was to test this integrated model PTSD in an analog sample who had experienced at least one traumatic event. Design: We used structural equation modeling to test the association of adult attachment and posttraumatic cognitions (self and world/others) with PTS and PTG using a cross-sectional, correlational design. Methods: The sample comprised 393 university staff and students (Range_Age= 18–49, 85% females) who completed online measures. Results: Attachment anxiety and negative posttraumatic self-cognitions were positively associated. Negative posttraumatic self-cognitions were positively associated with PTS. Attachment anxiety had an indirect effect (via negative posttraumatic self-cognitions) on PTS, whereas attachment avoidance predicted more negative posttraumatic world cognitions and lower perceived PTG. Conclusions: The study highlights the importance of considering how attachment styles influence posttraumatic emotion regulation and cognitive processing of the trauma to determine posttraumatic mental health.     

Exploring Correlates of Alcohol-Specific Social Reactions in Alcohol-Involved Sexual Assaults

This exploratory study examined demographic, assault, and disclosure factors as predictors of survivors’ decisions to disclose preassault alcohol use and social reactions to their preassault alcohol use. Of survivors drinking prior to assault, those with more education and greater alcohol impairment or resistance during assault were more likely to disclose preassault drinking. Of women disclosing preassault drinking, those with more education and more violent assaults received more negative social reactions specific to their preassault drinking. Such negative reactions were more common for those telling parents, police, or medical professionals. Women with less education received more positive and negative social reactions specific to their preassault drinking. Disclosing preassault drinking in greater detail was related to positive social reactions specific to preassault drinking and greater alcohol impairment during assault was associated with both positive and negative social reactions specific to preassault drinking. Implications for research and intervention are provided for survivors disclosing alcohol-related sexual assaults.     

Fear of Failure Biases Affective and Attentional Responses to Lexical and Pictorial Stimuli

The purpose of this investigation was to examine whether attentional biases would be noticed among individuals differing in levels of fear of failure (FF) as they viewed pictorial and lexical stimuli depicting various affective content. Indices of natural selective attention, namely, viewing time and self-reported affect, were assessed in 137 college students during free viewing picture and word presentation conditions. As hypothesized, FF was (a) negatively associated with self-reported dominance and valence for failure- and unpleasant-themed stimuli, and (b) positively associated with arousal ratings for unpleasant pictures. Although initially suppressed by neuroticism, partial correlation coefficients revealed a significant positive relationship between FF and viewing time for failure pictures. Results are discussed in the context of current theories of emotional reactivity and attentional biases pertaining to the nature of FF. Recommendations are provided for future research to elaborate the mechanisms involved in detrimental effects of FF.

Preschool child care and parents' use of physical discipline

Parenting practices, including the use of physical discipline, are shaped by multiple influences. Although much research focuses on how parent, child, and dyadic characteristics shape parenting practices, extra‐familial resources may also play a role. This paper focuses on how children's experiences of child care during the preschool years may affect one aspect of parenting—discipline practices. Using a rich, nationally representative data set, we explore the correlation between children's participation in centre based care, Head Start, or other non‐parental care arrangements and parents' use of physical discipline, and related phenomena, parents' experience of domestic violence and parenting stress. We conduct probit regressions of parents' use of physical discipline, and parents' experiences of domestic violence, on preschool child care experiences. For disadvantaged groups of children, who have higher risks of experiencing physical discipline and witnessing family violence, we find that Head Start participation is associated with an increase in the likelihood that parents say they never spank their children and reduction in reports of domestic violence. And, for children in two‐parent families, Head Start is associated with an increase in the likelihood that parents say they never spank their children and the likelihood that they do not say they would resort to spanking in a hypothetical situation. However, we find no evidence that non‐parental child care is associated with a lasting reduction in parenting stress. Copyright © 2005 John Wiley & Sons, Ltd.     

Attachment style differences in the processing of attachment–relevant information: Primed–style effects on recall,interpersonal expectations,and affect

The present study explored processing biases resulting from manipulating the temporal accessibility of relational schemas. By priming relational schemas, relationship–specific attachment styles were activated and their biasing effect on relevant information processing (namely recall for attachment–relevant words versus other words, interpersonal expectations, and affect) was examined. It was found that participants primed with a secure–style relational schema recalled more positive attachment words than those primed with an avoidant style. Although pre–priming endorsements of interpersonal expectations were influenced by global attachment style, once primed, participants showed primed–style–congruent responses. That is, primed secures showed higher endorsement of positive and lower endorsement of negative interpersonal expectations relative to the other primed style groups. Finally, primed secures reported more positive and less negative affect than the other primed style groups. Implications for understanding the way differential attachment experiences influence close relationships through life are considered.
