Too much to count on: impaired very small numbers in corticobasal degeneration

Patients with corticobasal degeneration (CBD) have calculation impairments. This study examined whether impaired number knowledge depends on verbal mediation. We focused particularly on knowledge of very small numbers, where there is a precise relationship between a cardinality and its number concept, but little hypothesized role for verbal mediation. We evaluated accuracy and reaction time (RT) for matching dot arrays and Arabic numerals involving smaller (2-4) and larger (5-9) cardinalities in non-aphasic patients with CBD (n=16), frontotemporal dementia (FTD; n=23), and healthy controls (n=15). CBD were less accurate and slowed at judging smaller Arabic numeral-dot array stimuli compared to FTD patients and controls. Moreover, only CBD showed longer RTs judging successively larger number-dot array pairs among the smaller cardinalities. Difficulty judging very small numbers is impaired in CBD, suggesting degraded representation of precise number knowledge that does not depend on language functioning.     

Differential Daily Writing Contingencies and Performance on Major Multiple-Choice Exams

On 4 of 7 days in each unit of an undergraduate human development course, students responded in writing to specific questions related to instructor notes previously made available to them. The study compared the effects of three writing contingencies on the quality of student writing and performance on major multiple-choice exams in the course. The three contingencies were (1) receiving credit for all writing products each unit, (2) receiving credit for one randomly selected writing product each unit, and (3) receiving no credit for any writing product each unit. On all dimensions of exam performance, writing for daily credit produced higher scores than did writing for random credit and writing for no credit. The daily-writing contingency also produced the highest writing ratings across all units; the writing for random credit produced the next highest writing scores; and the writing for no credit yielded the lowest writing scores. Across all three contingencies, writing scores were highly correlated with performance on multiple-choice exams.     

Braiding Two Evidence-Based Programs for Families At-Risk: Results of a Cluster Randomized Trial

Child maltreatment is a significant public health problem best addressed through evidence-based parent-support programs. There is a wide range of programs with different strengths offering a variety of options for families. Choosing one single evidence-based program often limits the range of services available to meet the unique needs of families. This paper presents findings from a study to examine the systematic braiding of two evidence-based programs, Parents as Teachers and SafeCare at Home (PATSCH), with the goal to provide a more robust intervention for higher risk families. A cluster randomized effectiveness trial was conducted to examine if PATSCH improved parenting behaviors known to decrease the risk for child maltreatment compared to Parents as Teachers (PAT) Alone. Parents (N?=?159; 92 PAT Alone; 67 PATSCH) were enrolled to complete a baseline, 6-month and 12-month assessment. Results indicate the groups did not differ on number of environmental hazards in the home, parents’ health care decision-making abilities, child abuse potential, and physical assault over time. However, with regard to the potential for child abuse, the PATSCH group showed a decrease in nonviolence discipline and increase in psychological aggression compared to the PAT group. Further research is needed to better examine this concept and its implications for the field.     

Cognitive factors associated with depression and anxiety in adolescents: A two-year longitudinal study

Background/Objective: To examine the roles of anxiety sensitivity and attentional bias in the development of anxiety and depression symptoms among adolescents. Method: 214 grade 7 to grade 10 Hong Kong Chinese students completed a package of psychometric inventories to measure levels of anxiety sensitivity, selective attentional processing, and anxiety and depressive symptoms in 2016 and then again in 2017. Results: Girls, when compared with boys, exhibited more anxiety symptoms and anxiety sensitivity in 2016. They also reported a significant increase in mean depression level from 2016 to 2017. Regression analyses revealed that the physical-concerns dimension of anxiety sensitivity, positive attentional bias, and to a lesser extent negative attentional bias were related to the development of both anxiety and depression symptoms one year later. Fear of mental incapacity could predict depression one year later but not anxiety symptoms. Conclusions: Intervention through anxiety sensitivity training to reduce somatic concerns and attentional bias modification to increase habitual attention to positive stimuli and to disengage from negative stimuli can reduce anxiety and depression symptoms among high school students.     

EMS Perspectives on Coping with Child Death in an Out-of-Hospital Setting

To understand the ways that EMS providers cope with pediatric death in an out-of-hospital setting, eight focus groups were conducted with 98 urban, rural, and suburban EMS providers. Sixty-eight of the participants also completed a short questionnaire about a specific event. In both the focus groups and questionnaire, participants were asked how they individually coped with the death, how they coped as a team, and what coping strategies were most and least helpful. Specific coping strategies were found to be helpful to EMS providers, and could be classified as Solve, Solace, Dismiss, and Escape based on whether they approached or avoided the problem or the emotion.     

College Students' Judgments of Verbal Sexual Harassment1

Most studies of sexual harassment focus on physical coercion or pressure for sexual favors. This research attempts to outline the factors involved in verbal sexual harassment, which is conceived of as a speech act similar to taboo language, with conversational “rules” and semantic categories that differentiate it from merely inappropriate language. One hundred thirty-seven college students rated 37 sexual remarks for degrees of sexual harassment and inappropriateness. Total harassment scores correlated with total appropriateness scores at r = .68; although harassment ratings were high, remarks were judged more inappropriate than harassing. Five harassment factors and six appropriateness factors emerged. Women rated harassment factors of euphemisms and obscenity as significantly more harassing, and appropriateness factors of objectification, belittling competency, and name calling as more inappropriate. We conclude that men, who are less likely to be targets of harassment, are more used to taboo language and “naming” games, and are reluctant to admit to harassment, even when remarks are deemed inappropriate. Practical implications for defining verbal sexual harassment are discussed.     

Wrapping services in an urban setting

Efforts to reform services for children and their families in Baltimore City have included providing Wraparound services to youth returned or diverted from out-of-state residential treatment. We briefly present the history and evolution of the system reform efforts in Baltimore City that were necessary to support the implementation of a Wraparound model of service delivery. The characteristics of the Wraparound service model is presented along with the referral pathway of the youth into the service system, the components of the service delivery system and an overview of step-down services and linkages utilized to transition the youth. Data are presented that demonstrate the level of community adjustment of a subset of the 121 youth served through the Wraparound model in contrast to the level of community adjustment achieved by nonequivalent comparison groups. We discuss the use of report card type of outcome measures, its user-friendly features, limitations, and the developmental steps needed to refine it further.     

Political distrust,perceived threat,and intentions to engage in normative and violent collective action: A mixed-methods study

In three studies, we examined the role of distrust and perceived threat in intentions to engage in normative and violent non-normative collective action. A field-based qualitative study of 35 pro-democracy protestors during the 2019 Hong Kong Anti-Extradition protests revealed that perceived threat to Hong Kong values alongside distrust of political institutions spurred collective action engagement and support for defensive violent collection action. In Study 2, a questionnaire (N = 639) testing pro-democracy action intentions demonstrated direct paths on both normative and violent collective action intentions from distrust and threat. In Study 3 (N = 133), experimental trust and threat manipulations demonstrated a significant association between distrust and threat on violent collective action intentions and acceptance, and a significant interaction on acceptance of violent collective action. Our results reveal the importance of distrust and threat in attitudinal support for, and engagement in, collective action and their role in transitioning from non-violent to violent collective action.
