Factor structure and measurement invariance of the Women's Health Initiative Insomnia Rating Scale

As part of the Women's Health Initiative Study, the 5-item Women's Health Initiative Insomnia Rating Scale (WHIIRS) was developed. This article summarizes the development of the scale through the use of responses from 66,269 postmenopausal women (mean age = 62.07 years, SD = 7.41 years). All women completed a 10-item questionnaire concerning sleep. A novel resampling technique was introduced as part of the data analysis. Principal-axes factor analysis without iteration and rotation to a varimax solution was conducted for 120,000 random samples of 1,000 women each. Use of this strategy led to the development of a scale with a highly stable factor structure. Structural equation modeling revealed no major differences in factor structure across age and race-ethnic groups. WHIIRS norms for race-ethnicity and age subgroups are detailed.     

The neural reality of syntactic transformations: evidence from functional magnetic resonance imaging

The functional anatomy of syntactic transformations, a major computational operation invoked in sentence processing, was identified through a functional magnetic resonance imaging investigation. A grammaticality judgment task was used, presented through a novel hidden-blocks design. Subjects listened to transformational and nontransformational sentences in which a host of other complexity generators (number of words, prepositions, embeddings, etc.) were kept constant. A series of analyses revealed that the neural processing of transformations is localizable, evoking a highly lateralized and localized activation in the left inferior frontal gyrus (Broca's region) and bilateral activation in the posterior superior temporal sulcus. The pattern of activation associated with transformational analysis was distinct from the one observed in neighboring regions, and anatomically separable from the effects of verb complexity, which yielded significant activation in the left posterior superior temporal sulcus. Taken together with neuropsychological evidence, these results uncover the neural reality of syntactic transformations.     

The acquisition of category structure in unsupervised learning

Four experiments examined the extent to which prior knowledge influences the acquisition of category structure in unsupervised learning conditions. Prior knowledge is general knowledge about a broad domain that explains why an object has the features it does. Category structure refers to the statistical regularities of features within and across categories. Subjects viewed items and then divided them up into the categories that seemed most natural. Each item had one feature that was related to prior knowledge and five features that were not. The results showed that even this small amount of prior knowledge helped subjects to discover the category structure. In addition, prior knowledge enhanced the learning of many of the category's features, and not just the features that were directly relevant to the knowledge. The results suggest that prior knowledge may help to integrate the features of a category, thereby improving the acquisition of category structure.     

Neuropsychological performance of emotionally disturbed students on the LNNB and LNNB-C

A number of researchers have reported an association between neuropsychological impairment and psychiatric disorders. However, there has been relatively little research on the neuropsychological functioning of emotionally disturbed students served in public schools. The purpose of this study was to determine the neuropsychological performance of 65 emotionally disturbed students 8–18 years old on the Luria-Nebraska Neuropsychological Battery: Form I (LNNB) and the Luria-Nebraska Neuropsychological Battery: Children's Revision (LNNB-C). The results indicated that approximately 42% of the younger group (99–154 months) and 38% of the older group (156– 226 months) demonstrated neuropsychological impairment as defined by criterion values for the various scales of the two batteries. On average, the emotionally disturbed students appeared to demonstrate more difficulty on more complex cognitive tasks, such as writing, arithmetic, and intellectual processes, than for less complex tasks, such as motor functions.     

Error monitoring in the hemispheres: the effect of lateralized feedback on lexical decision.

Does each hemisphere have its own system for monitoring and responding to errors? Three experiments investigate the effect of presenting lateralized accuracy feedback in a bilateral lexical decision task. We presented feedback after each trial in either the left visual field (LVF) or right visual field (RVF). In Experiment 1 the feedback stimuli were faces smiling or frowning, in Experiment 2 we used colored squares, and Experiment 3 tested the effect of verbal feedback. Negative feedback presented in the LVF tended to improve performance on the following trial, while the same negative feedback in the RVF tended to disrupt performance on the following trial. This result was strongest with the faces as feedback, was less pronounced with colored squares, and disappeared with verbal feedback. The results are interpreted as suggesting a right hemisphere superiority for error monitoring that depends on the mode of feedback.     

Infant-directed speech produced by fathers with symptoms of depression: effects on infant associative learning in a conditioned-attention paradigm

Infant-directed (ID) speech produced by fathers who varied in their number of self-reported symptoms of depressed was analyzed for differences its ability to promote infant voice-face associative learning. Infants of fathers with elevated scores on the Beck Depression Inventory-II (BDI-II) showed significantly poorer learning than did infants of fathers with non-elevated BDI-II scores when their fathers' ID speech served as a conditioned stimulus for a face reinforcer in a conditioned-attention paradigm. Fathers with elevated BDI-II scores produced ID speech with marginally significantly lower F0 variability than fathers with non-elevated BDI-II scores. However, F0-related cues were uncorrelated with infant learning. Overall, fathers' ID speech contained significantly less F0 modulation than did mothers' ID speech. These findings show that paternal depression, like maternal depression, adversely affects infant learning in a conditioned-attention paradigm.     

BACK TO ZECHARIAH FRANKEL AND LOUIS JACOBS? ON INTEGRATING ACADEMIC TALMUDIC SCHOLARSHIP INTO ISRAELI RELIGIOUS ZIONIST YESHIVAS AND THE SPECTRE OF THE HISTORICAL DEVELOPMENT OF THE HALAKHAH

This paper will discuss three new methods of teaching Talmud that Israeli Religious Zionist Yeshivas have adopted over the past two decades against the backdrop of the hitherto and perhaps still dominant approach to teaching Talmud in these Yeshivas, namely, the classical conceptual, ahistorical, highly abstract “Brisker” approach: (1) a modified Brisker approach; (2) the “Torat Eretz Yisrael,” “the Torah of the Land of Israel” approach; and (3) what I would call the “shiluv” approach, a term that implies forming a new and harmonious whole. What these three approaches have in common is the desire to retain the conceptual analysis of the Brisker approach, but to abandon its strict formalism and combine it with the search for religious meaning and significance. However, while the first two approaches in their search for the religious significance of the text generally eschew the use of the critical methodologies employed by academic Talmudic scholarship, the third approach embraces the use of those methodologies and seeks to integrate them into the world of traditional Talmud study. I will focus on the theological challenges raised by this attempted integration and on how the exponents of the “shiluv” approach have sought to deal with them.
