The factors that predicted variability in responses to phonemic awareness training were investigated in kindergartners who live in poverty. Treatment children (n=42) received both analytic and synthetic phonemic awareness computer-assisted instruction, while controls (n=34) received no special training. Mean age of participants was approximately 5 years 7 months. Pretests included initial phonemic awareness, letter knowledge, word-level reading, invented spelling, vocabulary knowledge, and print concepts. Spelling skills emerged as the best consistent predictor of variability in phonemic awareness in response to instruction. We propose that relations between phonemic awareness and spelling skills are bidirectional: Spelling influenced growth in phonemic awareness and phonemic awareness contributed to growth in spelling skills. The amount of exposure that children had to the treatment intervention contributed uniquely to individual differences in posttest levels of phonemic awareness and spelling. 相似文献

Functional MRI (fMRI) was used to examine the relationship between processing of pleasant and unpleasant stimuli and activity in prefrontal cortex. Twenty volunteers identified the colors in which pleasant, neutral, and unpleasant words were printed. Pleasant words prompted more activity bilaterally in dorsolateral prefrontal cortex (DLPFC) than did unpleasant words. In addition, pleasant words prompted more activity in left than in right DLPFC. Response speed to pleasant words was correlated with DLPFC activity. These data directly link positive affect, enhanced performance, and prefrontal activity, providing some of the first fMRI evidence supporting models of emotional valence and frontal brain asymmetry based on electroencephalography (EEG). 相似文献

We investigate whether two-digit numbers are decomposed for purposes of numerical comparison (e.g., choosing the larger one). Earlier theorists concluded that numbers are processed holistically (Brysbaert, 1995; Dehaene, Dupoux, & Mehler, 1990), or that holistic and decomposed processes operate in parallel (Nuerk, Weger, & Willmes, 2001). In the present experiment, we presented pairs of two-digit numbers with a decade distance of either zero (e.g., 54-57) or one (54-61). If a holistic process contributes to two-digit comparison, there should be an overall distance effect for number pairs with a decade distance of one. On the other hand, if numbers are decomposed and a holistic comparison does not contribute, this overall distance effect should be absent for these number pairs. Evidence is found that, at least in the present task settings, numbers are not compared holistically. The results are interpreted in terms of a recently proposed theory of numerical cognition (Verguts & Fias, 2004; Verguts, Fias, & Stevens, in press). 相似文献

Articles in the journal of Addictions and Offender Counseling between 1979 and 1998 were analyzed according to authors' demographic characteristics and article content to provide a historical review of the addictions and offender counseling field. Study results, historical trends, and future implications are presented. 相似文献

Self‐efficacy has been shown to be a robust predictor of exercise and other health‐related behaviors (e.g., Bandura, 1986, 1995, 1997; Godin, Desharnais, Valois, & Bradet, 1995; Maddux, 1995; McAuley, Wraith, & Duncan, 1991). Maddux has proposed that there are different types of self‐efficacy and that these types may fulfill different roles in the motivation of behavior, perhaps based on characteristics of the target behavior. The purpose of this study was to examine 3 different types of self‐efficacy: task, coping, and scheduling and their respective usefulness in distinguishing among persons reporting different levels of exercise involvement. A cross‐sectional telephone survey using exercise behavior as the selection criterion was completed with 203 adults. Results showed that coping and scheduling efficacy were the best disciminators of level of exercise behavior. Task efficacy did not clearly distinguish between exercise groups. The theoretical and applied implications are discussed, particularly noting specific targets for future intervention. 相似文献

In 2 experiments, humans received sequences of patterns that were similar (AX-->BX, AY-->BY, AZ-->BZ) or dissimilar (CX-->DY, CY-->DZ, CZ-->DX). The patterns were portrayed as bugs that could be eliminated with 2 insecticide sprays (red or blue). Either spray eliminated bugs with Features A and C, and participants learned by trial and error to use one spray (e.g., red) to eliminate bugs with Feature B and the other spray (e.g., blue) to eliminate those with Feature D. In Experiment 1, participants' spray choice for bugs with Feature A came to match that used to eliminate bugs with Feature B, but there was no such associative transfer between Features C and D. That is, similarity promoted associative transfer of responding between paired patterns when the features used to manipulate similarity (i.e., X, Y, and Z) were irrelevant. In Experiment 2, in which X, Y, and Z were relevant to the solution of configural discrimination, similarity hindered such associative transfer. These results complement those found in pigeons (R. A. Rescorla & D. J. Gillan, 1980) and indicate that similarity should not be accorded independent status as a principle of associative learning. 相似文献

There is currently a void in the literature regarding the kinds of support women find most beneficial when dealing with a
spouse’s sexually addictive or compulsive behaviors. Addressing this void is particularly relevant for clergy, seeing as they
are increasingly sought out as an initial and/or primary support for dealing with this marital issue. Using grounded theory
methodology, 22 women from Canada and the USA were interviewed to find out what they found most helpful as they sought support
to cope with a spouse’s sexually addictive and compulsive behaviors. Insights for pastoral counselors and clergy were highlighted. 相似文献

Basic quantitative genetic models of human behavioral variation have made clear that individual differences in behavior cannot be understood without acknowledging the importance of genetic influences. Yet these basic models estimate average, population-level genetic and environmental influences, obscuring differences that might exist within the population and masking systematic transactions between specific genetic and environmental influences. This article discusses a newer, more sophisticated and powerful quantitative genetic model that articulates these transactions. Results from this model highlight the ways in which the gene- environment interaction and correlation are intertwined. They can be used to integrate findings from quantitative and molecular genetic studies and to understand the roles of genetic influences and social forces in manifested behaviors, even when DNA sequence variation is not relevant. 相似文献
