Examination of a Regressive Prompt-Delay Procedure for Improving Sight-Word Reading

The current two-experiment study examined the effects of a regressive prompt-delay procedure on sight-word reading of four elementary school students. In contrast to traditional progressive prompt-delay procedures in which the latency of prompts is increased, the regressive prompt-delay latency is decreased over time. Data indicate that participants learned sight words quickly and maintained responding at high levels when instruction was withdrawn across both regressive and progressive prompt-delay conditions. Results are discussed in context of empirically supported prompting strategies and possible motivating operations that might be introduced when the learner is instructed to respond more quickly than the experimenter in regressive prompt delay (e.g., a game-like activity that potentially makes the activity educational, engaging, and enjoyable for students).     

The effect of delayed responding on Stroop-like task performance among preschoolers

Forty-four preschoolers completed 2 conditions of a Stroop-like procedure (e.g., saying "boat" for car and "car" for boat) that differed in whether a 3-s delay was imposed before responding. The test card was visible during the delay period for half of the children and occluded for the other children. Preschoolers' interference control was significantly improved in the delay condition. There was no difference between the two delay variants (test card visible or occluded). Children were more prone to interference as testing progressed regardless of whether the delay was present. These results suggest that delays effectively reduce interference by reducing the potency of the competing response during test trials, although memory demands may moderate the effectiveness of delays.     

Go naked: diapers affect infant walking

In light of cross‐cultural and experimental research highlighting effects of childrearing practices on infant motor skill, we asked whether wearing diapers, a seemingly innocuous childrearing practice, affects infant walking. Diapers introduce bulk between the legs, potentially exacerbating infants’ poor balance and wide stance. We show that walking is adversely affected by old‐fashioned cloth diapers, and that even modern disposable diapers – habitually worn by most infants in the sample – incur a cost relative to walking naked. Infants displayed less mature gait patterns and more missteps and falls while wearing diapers. Thus, infants’ own diapers constitute an ongoing biomechanical perturbation while learning to walk. Furthermore, shifts in diapering practices may have contributed to historical and cross‐cultural differences in infant walking.     

The Value of Symbolic Computation

Standard generative linguistic theory, which uses discrete symbolic models of cognition, has some strengths and weaknesses. It is strong on providing a network of outposts that make scientific travel in the jungles of natural language feasible. It is weak in that it currently depends on the elaborate and unformalized use of intuition to develop critical supporting assumptions about each data point. In this regard, it is not in a position to characterize natural language systems in the lawful terms that ecological psychologists strive for. Connectionist learning models offer some help: They define lawful relations between linguistic environments and language systems. But our understanding of them is currently weak, especially when it comes to natural language syntax. Fortunately, symbolic linguistic analysis can help connectionism if the two meet via dynamical systems theory. I discuss a case in point: Insights from linguistic explorations of natural language syntax appear to have identified information structures that are particularly relevant to understanding ecologically appealing but analytically mysterious connectionist learning models.     

Students’ Motivation and Engagement Predict Reading Achievement Differently by Ethnic Group

The authors examined Grade 3 and Grade 5 teacher-rated classroom engagement and student self-reported motivation for reading as predictors of reading achievement. They investigated the patterns of prediction of achievement for three racial/ethnic groups (White, Black, and Hispanic) and five levels of socioeconomic status (SES) in a combined within-group model. Groups were created by crossing race/ethnicity with SES to form 15 independent groups for each grade level. Results indicated that self-reported motivation was a significant predictor of reading achievement mainly for White third-grade students; teacher-reported engagement was a better predictor for all racial/ethnic groups for both Grade 3 and Grade 5 reading achievement. Results show higher achievement for White and higher-SES students compared with non-White and lower-SES students.     

Experiencing Racial Humor with Outgroups: A Psychophysiological Examination of Co-Viewing Effects

Research on co-viewing (or group viewing) is scarce. Yet, co-viewing has important implications for the viewers’ entertainment experience and the way viewers respond to and evaluate entertainment—especially those with controversial messages. The present study investigated responses to racial humor content among racial in-group and out-group viewing contexts. Specifically, the study examined the extent to which Blacks and Whites would experience discomfort when viewing racial slurs in comedies with in-group compared to out-group members. Employing real-time psychophysiological data and multilevel time series models, the study found a significant increase in emotional arousal (indicated by SCRs) and distraction (indicated by RSA) among Blacks in the context of out-group viewing compared to in-group viewing, but not for Whites. Implications of findings are discussed.     

Relating lab to life: Decrements in attention over time predict math productivity among children with ADHD

A child’s ability to sustain attention over time (AOT) is critical in attention-deficit/hyperactivity disorder (ADHD), yet no prior work has examined the extent to which a child’s decrement in AOT on laboratory tasks relates to clinically-relevant behavior. The goal of this study is to provide initial evidence for the criterion validity of laboratory assessments of AOT. A total of 20 children with ADHD (7–12 years of age) who were enrolled in a summer treatment program completed two lab attention tasks (a continuous performance task and a self-paced choice discrimination task) and math seatwork. Analyses focused on relations between attention task parameters and math productivity. Individual differences in overall attention (OA) measures (averaged across time) accounted for 23% of the variance in math productivity, supporting the criterion validity of lab measures of attention. The criterion validity was enhanced by consideration of changes in AOT. Performance on all laboratory attention measures deteriorated as time-on-task increased, and individual differences in the decrement in AOT accounted for 40% of the variance in math productivity. The only variable to uniquely predict math productivity was from the self-paced choice discrimination task. This study suggests that attention tasks in the lab do predict a clinically-relevant target behavior in children with ADHD, supporting their use as a means to study attention processes in a controlled environment. Furthermore, this prediction is improved when attention is examined as a function of time-on-task and when the attentional demands are consistent between lab and life contexts.     

Technology and the Polytheistic Mind: From Global to Planetary Theologies

Abstract: Assuming that human beings are, among other things, techno‐sapiens, natural‐cultural; and that technology‐nature‐culture are a part of the same emergent process of life (e.g., Martin Heidegger, Donna Haraway, Phil Hefner), this paper argues for a move from global to planetary technologies. According to Gayatri Spivak, the process of globalization is the imposition of sameness over the face of the globe. In contrast, she argues, what we need is a planetary vision of the world: one that pays attention to multi‐perspectivalism and difference; and connects peoples, places, and things through those differences rather than in spite of them. In this article I argue that theological technologies of monotheism have tended to support globalization. As such, I explore the possibilities for polytheistic (or at least) polydox theological technologies of planetary becoming.     

Location, location, location: how it affects the neighborhood (effect)

Reaction times in lexical decision are more sensitive to a words' length and orthographic-neighborhood density when the stimulus is presented to the left visual field (LVF) than to the right visual field (RVF). We claim that the length effect is equivalent to the neighborhood effect, and propose a novel explanation of why the LVF, but not the RVF, is sensitive to density, based on different firing rates of abstract-letter representations encoding letters falling in the LVF versus RVF. We support this proposal with a large-scale implemented model of lexical decision utilizing spiking units, which provides a reasonable fit to the data from the English Lexicon Project under simulated central presentation, while replicating the observed hemifield asymmetries under simulated lateralized presentation.
