Effects of Improving the Reliability of the GPA on Prediction Generally and on Comparative Predictions for Gender and Race Particularly

The reliability of a method of adjusting grade point averages for differences in departmental grading standards was examined, as were the effects of such adjustments on the predictive validity of high school grades, SAT scores, and achievement test scores. The index of differential grading standards for all on-time graduates of the Dartmouth College class of 1986 was quite reliable, and its use in adjusting grade averages increased predictive validity, reduced its erosion over years, reduced the apparent underprediction of women, and improved predictions for blacks. Differential group enrollment in courses in the science division seems to account for much of the effect of adjustment on grades. Improvement in the reliability of the criterial grade averages also was shown to have similar effects on gender and race prediction in another data set     

Development and Prediction of Context-Dependent Vowel Pronunciation in Elementary Readers

ABSTRACT

As children learn to read, they become sensitive to context-dependent vowel pronunciations in words, considered a form of statistical learning. The work of Treiman and colleagues demonstrated that readers’ vowel pronunciations depend on the consonantal context in which the vowel occurs and reading experience. Using explanatory item-response models we examined child- and nonword-factors associated with children’s assignment of more versus less frequent grapheme-phoneme correspondences (GPC) to vowel pronunciations as a function of rime coda in monosyllabic nonwords. Students (N = 96) in grades 2-5 read nonwords in which more versus less frequent vowel GPCs were wholly supported or partially favored by the rime unit. Use of less frequent vowel GPCs was predicted by set for variability, word reading, and rime support for the context-dependent vowel pronunciation. We interpret the results within a developmental word reading model in which initially incomplete and oversimplified GPC representations become more context dependent with reading experience.     

Promoting Math Talk in Adult–Child Interactions Through Grocery Store Signs

Young children have better math abilities when their parents engage in more math‐related conversations with them. Yet, previous studies have found that math talk occurs only very infrequently in everyday interactions. In the present study, we sought to promote adult–child conversations about math in a naturalistic context using minimal instructions. We observed 179 adult–child dyads while they shopped in grocery stores with signs prompting them to engage in math‐related conversations (math condition), signs prompting them to talk about other topics (general language condition), or without any signs (baseline condition). In the math condition, more adults talked about math compared to the general language or the baseline condition, and this finding could not be explained by demographic characteristics of the dyad or the overall amount of conversations. This study demonstrates that cost‐effective signs placed in everyday contexts can promote math‐related conversations and potentially provide math learning opportunities for children.     

Student engagement and mathematics achievement: Unraveling main and interactive effects

The present study explored the relationships between student engagement and mathematics achievement for 295,416 15‐year‐old students from 11,767 secondary schools in 34 countries who participated in the Program for International Student Assessment (PISA) 2012. Affective engagement was measured by students’ mathematics interest (InterestMath) and perceived usefulness of schooling (PerceptionSch), behavioral engagement by behaviors facilitating mathematics learning (BehaviorMath) and participation in mathematics learning activities (ActivitiesMath), and cognitive engagement by openness (Openness) and perseverance (Perseverance) in problem‐solving. Results showed that students who were more engaged had higher levels of academic achievement, with cognitive engagement having the strongest association with achievement. Results also showed that students who were highly engaged in two domains had higher achievement levels than peers who were engaged in only one domain in six pairwise comparisons (InterestMath‐BehaviorMath, InterestMath‐Openness, InterestMath‐Perseverance, PerceptionSch‐BehaviorMath, PerceptionSch‐Openness, PerceptionSch‐Perseverance). These results highlighted the importance of a whole‐school based approach in enhancing student achievement.     

Prevalence and psychological sequelae of self-reported childhood physical and sexual abuse in a general population sample of men and women

OBJECTIVE: This study examined the prevalence and psychological sequelae of childhood sexual and physical abuse in adults from the general population. METHOD: A national sampling service generated a geographically stratified, random sample of 1,442 subjects from the United States. Subjects were mailed a questionnaire that included the Traumatic Events Survey (TES) [Traumatic Events Survey, Unpublished Psychological Test, Harbor-UCLA Medical Center, Los Angeles] and the Trauma Symptom Inventory (TSI) [Trauma Symptom Inventory Professional Manual, Psychological Assessment Resources, Odessa, FL]. Of all potential subjects, 935 (64.8%) returned substantially completed surveys. RESULTS: Sixty-six men and 152 women (14.2% and 32.3%, respectively) reported childhood experiences that satisfied criteria for sexual abuse, and 103 males and 92 females (22.2% and 19.5%, respectively) met criteria for physical abuse. Twenty-one percent of subjects with one type of abuse also had experienced the other type, and both types were associated with subsequent adult victimization. After controlling for demographics, adult history of interpersonal violence, and other child abuse, childhood sexual abuse was associated with all 10 scales of the TSI, and physical abuse was related to all TSI scales except those tapping sexual issues. Sexual abuse predicted more symptom variance than did physical abuse or adult interpersonal victimization. Various aspects of both physical and sexual abuse experiences were predictive of TSI scores. Abuser sex, however, both alone and in interaction with victim sex, was not associated with additional TSI symptomatology. CONCLUSIONS: Childhood sexual and physical abuse is relatively common in the general population, and is associated with a wide variety of psychological symptoms. These relationships remain even after controlling for relevant background variables.     

Only Familiar Information is a “Curse”: Children’s Ability to Predict What Their Peers Know

The ability to make inferences about what one’s peers know is critical for social interaction and communication. Three experiments (n = 309) examined the curse of knowledge, the tendency to be biased by one’s knowledge when reasoning about others’ knowledge, in children’s estimates of their peers’ knowledge. Four- to 7-year-olds were taught the answers to factual questions and estimated how many peers would know the answers. When children learned familiar answers, they showed a curse of knowledge in their peer estimates. But, when children learned unfamiliar answers to the same questions, they did not show a curse of knowledge. These data shed light on the mechanisms underlying perspective taking, supporting a fluency misattribution account of the curse of knowledge.

Childhood sexual abuse, attachment, and trauma symptoms in college females: the moderating role of attachment

OBJECTIVE: The present study tests a model linking attachment, childhood sexual abuse (CSA), and adult psychological functioning. It expands on previous work by assessing the degree to which attachment security moderates the relationship between a history of child sexual abuse and trauma-related symptoms in college females. METHOD: Self-reports of attachment, childhood sexual abuse, and adult psychological functioning were obtained from 324 female undergraduate students attending a Southeastern U.S. university. Separate analyses were conducted examining the potential moderating role for close-adult, parent-child, and peer attachment styles. RESULTS: In this sample, 37.7% of participants reported sexually abusive experiences prior to age 16. History of child sexual abuse was consistently associated with higher levels of trauma-related symptoms and lower levels of attachment security in close-adult, parent-child, and peer relations. Additionally, attachment security was consistently associated with trauma-related symptoms. Close-adult, parent-child, and peer attachment differentially moderated trauma-related symptoms. Specifically, in peer relationships, the strength of the relationships between attachment measures and trauma symptoms were greater for CSA survivors than for non-abused participants. The opposite pattern of results was found for attachment in parental and close-adult relationships. CONCLUSION: Results suggest that attachment security in peer and parent relationships protects against the negative effects of CSA, while only weak, marginally significant protective effects were observed for close-adult relationships. Only modest support was found for the conceptualization of attachment as a moderator of the relationship between CSA and trauma-related symptoms. However, the results suggest that attachment security at least partially protects against negative CSA outcomes.     

Fine-grained auditory discrimination and performance on tests of receptive vocabulary and receptive language

This research investigated the relation between children’s performance on two measures of receptive language and children’s auditory discrimination of consonant-vowel sounds having frequency and temporal acoustic differences. The measures of fine-grained auditory discrimination produced significant multiple regression coefficients against both receptive vocabulary (Peabody Picture Vocabulary Test-Revised) and receptive language (Token Test for Children) scores. Validation analyses conducted by predicting receptive vocabulary and language scores for a new sample of children and relating them to the actual scores led to significant outcomes. It was concluded that fine-grained auditory discrimination is particularly important in the relatively early stages of language learning. The cooperation of the participating children, teachers, principals, and school district administrators is gratefully acknowledged. This research was supported, in part, by a grant from NINCDS (NIH).
