Statistical learning is related to reading ability in children and adults

There is little empirical evidence showing a direct link between a capacity for statistical learning (SL) and proficiency with natural language. Moreover, discussion of the role of SL in language acquisition has seldom focused on literacy development. Our study addressed these issues by investigating the relationship between SL and reading ability in typically developing children and healthy adults. We tested SL using visually presented stimuli within a triplet learning paradigm and examined reading ability by administering the Wide Range Achievement Test (WRAT-4; Wilkinson & Robertson, 2006). A total of 38 typically developing children (mean age of 9;5 years, range 6;4-12;5) and 37 healthy adults (mean age of 21 years, range 18-34) were assessed. In children, SL was significantly related to reading ability. Importantly, this relationship was independent of grade and also age. The adult data, too, revealed that SL was significantly related to reading ability. A regression analysis of the combined child and adult data revealed that SL accounted for a unique amount of variance in reading ability, after age and attention had been taken into consideration. For the first time, this study provides empirical evidence that a capacity for more effective SL is related to higher reading ability in the general population.     

Patient and partner correlates of couple relationship functioning in bipolar disorder

Extensive research in unipolar depressed and population-based samples has shown cross-partner associations between depressive symptoms and relationship adjustment. Yet despite evidence that bipolar disorder (BPD) is a more chronic and severe illness than unipolar depression, that individuals with BPD are at risk for interpersonal dysfunction, and that critical, unsupportive relationships are predictive of the course of depressive symptoms in BPD, there have been limited efforts to understand the correlates of relationship functioning within BPD. The current study addresses this gap in the literature by examining the associations between the depressive and manic symptoms of individuals with BPD, their partner's depressive symptoms, and relationship functioning, using a multimethod, multi-informant approach. Results revealed that the depressive symptoms of the individual with BPD were associated with poorer relationship functioning, particularly when the partner without BPD also had elevated depressive symptoms. In addition, an interaction between the individual with BPD's depressive and manic symptoms was observed, such that manic symptoms were associated with increased observed hostility and poorer partner relationship adjustment, but only when depressive symptoms were also elevated. These effects persisted even after overall mental health of both partners was controlled.     

Refining the understanding of inhibitory processes: how response prepotency is created and overcome

Understanding (a) how responses become prepotent provides insights into when inhibition is needed in everyday life. Understanding (b) how response prepotency is overcome provides insights for helping children develop strategies for overcoming such tendencies. Concerning (a), on tasks such as the day‐night Stroop‐like task, is the difficulty with inhibiting saying the name of the stimulus due to the name being semantically related to the correct response or to its being a valid response on the task (i.e. a member of the response set) though incorrect for this stimulus? Experiment 1 (with 40 4‐year‐olds) suggests that prepotency is caused by membership in the response set and not semantic relation. Concerning (b), Diamond, Kirkham and Amso (2002) found that 4‐year‐olds could succeed on the day‐night task if the experimenter sang a ditty after showing the stimulus card, before the child was to respond. They concluded that it was because delaying children’s responses gave them time to compute the correct answer. However, Experiment 2 (with 90 3‐year‐olds) suggests that such a delay helps because it gives the incorrect, prepotent response time to passively dissipate, not because of active computation during the delay.     

Effectiveness of virtual reality for pediatric pain distraction during i.v. placement.

The objective of this study was to test the efficacy and suitability of virtual reality (VR) as a pain distraction for pediatric intravenous (i.v.) placement. Twenty children (12 boys, 8 girls) requiring i.v. placement for a magnetic resonance imaging/computed tomography (MRI/CT) scan were randomly assigned to two conditions: (1) VR distraction using Street Luge (5DT), presented via a head-mounted display, or (2) standard of care (topical anesthetic) with no distraction. Children, their parents, and nurses completed self-report questionnaires that assessed numerous health-related outcomes. Responses from the Faces Pain Scale-Revised indicated a fourfold increase in affective pain within the control condition; by contrast, no significant differences were detected within the VR condition. Significant associations between multiple measures of anticipatory anxiety, affective pain, i.v. pain intensity, and measures of past procedural pain provided support for the complex interplay of a multimodal assessment of pain perception. There was also a sufficient amount of evidence supporting the efficacy of Street Luge as a pediatric pain distraction tool during i.v. placement: an adequate level of presence, no simulator sickness, and significantly more child-, parent-, and nurse-reported satisfaction with pain management. VR pain distraction was positively endorsed by all reporters and is a promising tool for decreasing pain, and anxiety in children undergoing acute medical interventions. However, further research with larger sample sizes and other routine medical procedures is warranted.     

Lexical ambiguity and the timecourse of attentional allocation in word recognition

In two experiments the allocation of attention during the recognition of ambiguous and unambiguous words was investigated. In Experiment 1, separate groups performed either lexical decision, auditory probe detection, or their combination. In the combined condition probes occurred 90, 180, or 270 ms following the onset of the lexical-decision target. Lexical decisions and probe responses were fastest for ambiguous words, followed by unambiguous words and pseudowords, respectively, which indicated that processing ambiguous words was less attention demanding than unambiguous words or pseudowords. Attention demands decreased across the timecourse of word recognition for all stimulus types. In Experiment 2, one group performed the lexical-decision task alone, whereas another group performed the lexical-decision task during the retention interval of a short-term memory task. The results were consistent with those from Experiment 1 and showed that word recognition is an attention-demanding process and that the demands are inversely related to the number of meanings of the stimulus. These results are discussed with regard to the structure of the mental lexicon (i.e., single vs. multiple lexical entries) and the effect of such a structure on attentional mechanisms.     

The daughters of charlotte ray: The career development process during the exploratory and establishment stages of black women attorneys

This exploratory study examines the career development process of Black women in the legal field. The purpose of the study was to gain an understanding of the factors that enable minority women to enter atypical professions and overcome the dual discriminatory obstacles of race and sex. The specific objectives of the study were to determine the impact of sociocultural variables on the career choice process of minority women during the career entry and establishment stages (Super, 1957). The study was focused on the influence of educational values in the home; economic resources of the family, significant role models, legislated educational parity policies such as Brown vs. Board of Education, university affirmative action, and minority recruitment programs.This study was written as part of a grant from the Rockefeller Foundation.     

The precarious enterprise of ministry

The effect of the cultural values of rationalization and individualism upon the status of the parish minister is discussed. These values make the minister's status precarious because role behavior is difficult to interpret in terms of them. Some defenses against precariousness are outlined.This paper was read at the session, Ministry Studies: The Contribution of Samuel W. Blizzard, convened at the annual meeting of the Religious Research Association, Milwaukee, Wisconsin, October 1975. The late Samuel Wilson Blizzard was Maxwell M. Upson Professor of Christianity and Society at Princeton Theological Seminary.
