Speed and Rhythm Affect Temporal Structure of Variability in Reaching Poststroke: A Pilot Study

Temporal structure reveals the potential adaptive strategies employed during upper extremity movements. The authors compared the temporal structure of upper extremity joints under 3 different reaching conditions: preferred speed, fast speed, and reaching with rhythmic auditory cues in 10 individuals poststroke. They also investigated the temporal structure of these 3 reaching conditions in 8 healthy controls to aid in the interpretation of the observed patterns in the poststroke cohort. Approximate entropy (ApEn) was used to measure the temporal structure of the upper extremity joints. ApEn was similar between conditions in controls. After stroke, ApEn was significantly higher for shoulder, elbow, and wrist both at fast speed and with rhythmic cues compared with preferred speed. ApEn at index finger was significantly higher only with rhythmic cues compared with preferred speed. The authors propose that practice reaching at faster speed and with rhythmic cues as a component of rehabilitation interventions may enhance adaptability after stroke.     

Emotion regulation choice in an evaluative context: the moderating role of self-esteem

Evaluative contexts can be stressful, but relatively little is known about how different individuals who vary in responses to self-evaluation make emotion regulatory choices to cope in these situations. To address this gap, participants who vary in self-esteem gave an impromptu speech, rated how they perceived they had performed on multiple evaluative dimensions, and subsequently chose between disengaging attention from emotional processing (distraction) and engaging with emotional processing via changing its meaning (reappraisal), while waiting to receive feedback regarding these evaluative dimensions. According to our framework, distraction can offer stronger short-term relief than reappraisal, but, distraction is costly in the long run relative to reappraisal because it does not allow learning from evaluative feedback. We predicted and found that participants with lower (but not higher) self-esteem react defensively to threat of failure by seeking short-term relief via distraction over the long-term benefit of reappraisal, as perceived failure increases. Implications for the understanding of emotion regulation and self-esteem are discussed.     

Prolonged institutional rearing is associated with atypically large amygdala volume and difficulties in emotion regulation

Early adversity, for example poor caregiving, can have profound effects on emotional development. Orphanage rearing, even in the best circumstances, lies outside of the bounds of a species-typical caregiving environment. The long-term effects of this early adversity on the neurobiological development associated with socio-emotional behaviors are not well understood. Seventy-eight children, who include those who have experienced orphanage care and a comparison group, were assessed. Magnetic resonance imaging (MRI) was used to measure volumes of whole brain and limbic structures (e.g. amygdala, hippocampus). Emotion regulation was assessed with an emotional go-nogo paradigm, and anxiety and internalizing behaviors were assessed using the Screen for Child Anxiety Related Emotional Disorders, the Child Behavior Checklist, and a structured clinical interview. Late adoption was associated with larger corrected amygdala volumes, poorer emotion regulation, and increased anxiety. Although more than 50% of the children who experienced orphanage rearing met criteria for a psychiatric disorder, with a third having an anxiety disorder, the group differences observed in amygdala volume were not driven by the presence of an anxiety disorder. The findings are consistent with previous reports describing negative effects of prolonged orphanage care on emotional behavior and with animal models that show long-term changes in the amygdala and emotional behavior following early postnatal stress. These changes in limbic circuitry may underlie residual emotional and social problems experienced by children who have been internationally adopted.     

Social and Personal Factors as Predictors of Earthquake Preparation: The Role of Support Provision,Network Discussion,Negative Affect,Age, and Education1

Panel data collected in 1991 as part of the University of Southern California Longitudinal Study of Generations (LSOG) were used to predict reported preparation activities prior to and in response to the 1994 Northridge, California, earthquake. In late 1994 and early 1995, 163 panelists (representing 107 multigenerational families) were interviewed by phone about their earthquake experiences. The best 1991 predictor of pre‐quake preparation was the extent of instrumental support respondents provided to network members. Earthquake preparation activities undertaken after the quake were associated with the amount and cost of damage experienced during the quake, 1991 neuroticism scores, age (inversely), and having preparedness encouraged by multiple network sources. The results highlight the importance of social roles (e.g., support provision) and discussion by informal network sources in the adoption of public health and safety messages.     

Messages about the uniqueness and similarities of people: Impact on U.S. Black and Latino youth

This experiment examined the impact of messages about uniqueness and similarity between groups of people on Black and Latino children's social attitudes. Children (ages 11–14) read two brief science books embedded with a similarities message (“all people are basically the same”), unique message (“each person is unique”), combined similar-unique message (“all people are the same in a way, but each person is also unique”), or no additional message (control). Relative to the other conditions, the combined condition increased general social tolerance and decreased desired social distance from White children. No message appeared to negatively impact participants' attitudes toward their own group. Implications of these results for basic and applied anti-bias work on promoting similarities, differences, or both are discussed.     

Auditory processing measures: correlation with neuropsychological measures of attention, memory, and behavior.

It has been suggested that measures of auditory processing (AP) are sensitive measures of attention resulting in the high comorbidity of auditory processing disorder (APD) and attention deficit/hyperactivity disorder (ADHD). Others have found that selected AP measures share significant variance with memory tasks. The current study investigated the relation between AP measures and various neuropsychological measures presumed to measure attention and memory in 36 children with a mean age of 7.78 years (SD=1.61) referred to an outpatient facility. Results indicate that AP measures significantly correlated with each other as well as with some measures of attention, memory, and behavior ratings. Results suggest that although AP measures include elements of both attention and memory, these measures also appear to assess processes not tapped by other measures of attention and memory. The correlation of AP measures with parent-and teacher-rated withdrawal, parent-rated somatization, conduct, and depression, as well as teacher-rated attention, anxiety, learning problems, social skills, and leadership suggest that auditory processing problems may manifest in myriad behaviors across settings. Implications for practice and future research are presented.     

Love, Suspense, Sex, and Violence: Men’s and Women’s Film Predilections, Exposure to Sexually Violent Media, and their Relationship to Rape Myth Acceptance

This investigation addressed the relationship between men’s and women’s predilections for film with a love story, suspense, or sex and violence theme and how that predilection related to rape myth acceptance (RMA). Also examined was how men’s and women’s predilections, as they related to RMA, were moderated by exposure to different levels of sexually violent media based on a true story. Finally, the relationship between traditional attitudes and film predilection, as well as the relationship between film predilection and attitudes toward film editing, were investigated. Results indicate that men prefer film with sex and violence significantly more than women do, whereas women prefer love stories significantly more than men do. Those with sex and violence film predilections are more accepting of RMA than those with love story or suspense predilections. Women’s film predilections and their relationship to RMA attitudes are moderated to an extent by exposure to sexually violent media based on a true story, whereas men’s attitudes remain unaffected. Finally, those with sex and violence film predilections are less in favor of film editing than are those with suspense or love story predilections. Theoretical explanations for the findings are discussed and their implications.     

Collaboration with Urban Community Stakeholders: Refining Paraprofessional‐led Services to Promote Positive Parenting

This paper describes the process of a community–academic partnership to navigate implementation challenges for a school‐based service model led by paraprofessionals to promote positive parenting in high poverty urban communities. We describe the process by which we (a) identified implementation challenges, (b) sustained a university–community collaboration to redesign the paraprofessional service model, and (c) assessed the feasibility of the new model involving four social service agencies in 16 schools with over 600 families. The structure and process of the collaboration and refinement are described with attention to who was best positioned to engage in the collaboration and how the partnership worked to balance scientific rigor with responsiveness to paraprofessional workforce strengths. Feasibility data indicated that the revised model was successfully implemented by paraprofessional staff; 92.2% of possible staff monthly reports were completed and discussion of key goals was incorporated into 94.2% of interactions. Continual monitoring provided critical feedback from stakeholders as we drew on and interpreted these various sources of information to build and refine the service model. We suggest that these processes are critical steps to bridge the research‐to‐practice gap, by promoting practices that are aligned with the needs of children and families, and the staff who serve them.     

Marital conflict and support seeking by parents in adolescence: empirical support for the parentification construct

Parentification, a parent-child dynamic wherein children come to provide ongoing emotional support for their parents, has been documented extensively in the clinical literature; however, it rarely has been studied systematically. Using a community sample of 83 couples and their adolescent children (mean age = 15.26 years; 52% male, 48% female), the authors linked adolescent self-report of parentification to specific youth and adult behaviors using multiple methods and examined its associations with youth adjustment problems. The parentification measure demonstrated strong internal consistency and 1-year stability. Parentification was associated with marital conflict, youth perceptions of threat, low warmth in the parent-child relationship, and the tendency for youths to intervene in marital conflict. Links were also found with youth reports of internalizing and externalizing behavior and poorer competency in close friendships. These findings thus support the parentification construct and provide evidence that parentification may contribute to poor youth outcomes by burdening children with developmentally inappropriate responsibilities.
