Executive function performance and trauma exposure in a community sample of children

ObjectiveThough children exposed to familial violence are reported to have difficulties with a range of emotional and behavioral problems (e.g., lower school achievement) that implicate executive function (EF) deficits, relatively little research has specifically examined EF as a function of trauma exposure in children.MethodsBased on parent report of children's exposure to potentially traumatic events, children (N = 110; Age_Mean = 10.39) from an ethnically diverse community sample were compared across three trauma-exposure groups: familial trauma, non-familial trauma, and no trauma. Children completed a battery of tests to assess working memory, behavioral inhibition, processing speed, auditory attention, and interference control.ResultsFamilial trauma (relative to non-familial and no trauma exposure) was associated with poorer performance on an EF composite (composed of working memory, inhibition, auditory attention, and processing speed tasks); the effect size was medium. Both trauma-exposure status and dissociation symptoms explained unique variance in EF performance after controlling for anxiety symptoms, socio-economic status, and potential traumatic brain injury. While IQ and EF performance were related, SES predicted unique variance in IQ (and not EF) scores, while familial-trauma exposure did not.ConclusionsThe contribution of trauma exposure to basic executive functioning held after taking into account symptoms (anxiety and dissociation), socio-economic status, and possible traumatic brain injury exposure. EF problems may provide one route via which maltreated children become at risk for peer, academic, and behavior problems relative to their peers.Practice implicationsEF problems may provide one route via which maltreated children become at risk for peer, academic, psychological, and behavior problems relative to their peers. Recently, intervention strategies have emerged in the anxiety and mood disorder treatment literatures that appear to effectively target EFs. As future research continues to specify the relationship between child trauma exposure and EF performance, these innovative treatments may have important practice implications for addressing EF deficits.     

Effects of caption modification and instructor intervention on comprehension of a technical film

Two versions of a technical film, captioned at approximately 8th- and 11th-grade reading levels, were shown to 32 hearing-impaired college students. Fifteen of these students also received supplementary instruction from a teacher. Data from a comprehension test were analyzed with a four-factor experimental design to determine effects of instruction, level of captioning, test type (recall or recognition), and subject reading ability. Significant effects were found for instruction, test type, and reading ability. In addition, there was a significant three-way interaction between instruction, caption level, and reading ability. While both high and low reading groups benefited from instruction when students viewed 8th-grade level, modified captions, only the high reading group benefited from instruction when they viewed the 11th-grade level, original captions.This research was conducted in the course of an agreement with the U.S. Office of Education.     

Traveling the road to success: A discourse on persistence throughout the science pipeline with African American students at a predominantly white institution

This study focuses on 11 African American undergraduate seniors in a biology degree program at a predominantly white research institution in the southeastern United States. These 11 respondents shared their journeys throughout the high school and college science pipeline. Participants described similar precollege factors and experiences that contributed to their academic success and persistence at a predominantly white institution. One of the most critical factors in their academic persistence was participation in advanced science and mathematics courses as part of their high school college preparatory program. Additional factors that had a significant impact on their persistence and academic success were family support, teacher encouragement, intrinsic motivation, and perseverance. © 2005 Wiley Periodicals, Inc.     

Science in the schoolhouse: an uninvited guest

Science and scientific thinking have not made a substantial impact on educational practice. In this discussion, we examine the relationship between science and education and delineate four reasons for characterizing science as an uninvited guest in schools: (a) Science is not highly regarded in society; (b) good science and bad science are often mistaken for one another; (c) the amount of current data is overwhelming; and (d) science is not easy for those who practice it (researchers), those who translate it (teacher educators), or those who consume it (teachers). We suggest several strategies to improve this relationship, including promoting standards of educational practice, emphasizing the role of teacher educators as translators of the research base into classroom practice, and linking student outcomes with the use of effective instructional practices.     

College student performance on the general ability measure for adults and the wechsler intelligence scale for adults‐third edition

This study examined the concurrent validity of the General Ability Measure for Adults (GAMA¹; Naglieri & Bardos, 1997) and the Wechsler Adult Intelligence Scale‐Third Edition (WAIS‐III; Wechsler, 1997). Sixty college students were administered both instruments in counterbalanced order. A comparison of the mean scores on the GAMA and WAIS‐III indicated that the sample obtained similar GAMA and WAIS‐III PIQ scores. In contrast, the sample's mean GAMA IQ score was significantly lower than the sample's mean FSIQ and VIQ scores. Although the GAMA IQ score was positively correlated with all WAIS‐III IQ and Index scores, this new instrument was more clearly associated with visual‐spatial reasoning, as defined by the WAIS‐III PIQ. The GAMA's accuracy in predicting performance on the WAIS‐III FSIQ and PIQ also was examined, with the GAMA underestimating WAIS‐III FSIQ and PIQ scores for participants falling within the Superior and Very Superior range of intellectual functioning. © 2001 John Wiley & Sons, Inc.     

Surprise,Hurt, and Anger as Emotional Responses to Expectancy Violations Following Feedback Messages

ABSTRACT

Using expectancy violations theory, this study examined how the communication of unexpected feedback messages evoke emotional responses. A convenience sample (N = 309) reported instances of unexpected feedback within the last month. Results showed that receipt of the feedback message types were considered moderate-to-high violations. Violation expectedness and valence were negatively associated with the emotional responses, but violation importance was positively associated with the emotional responses. Finally, hurt and anger (but not surprise) were positively linked to perceptions of relational damage between the message sender and receiver. Taken together, our study demonstrates that expectancy violations are connected to emotions and relational outcomes.     

Mind the Gap! Making the Leap to Reach Distance Students Through On-Campus Events

When a mid-sized library at a private university held its first robust research-support event, a huge portion of the student body was noticeably absent – the distance population. The ACRL Standards for Distance Learning Library Services affirms that distance learners are entitled to the same services and resources as on-campus learners. This means that “service excellence in distance librarianship” should include conducting outreach programs for distance learners that parallels outreach programs for on-campus learners. This case study tracks the process of rethinking an on-campus event to incorporate distance learners. It is designed to communicate how a shift in thinking can create opportunities for outreach experiences by transforming existing events and/or extending programs the first time they are made available.
