The relation of white matter hyperintensities to cognitive performance in the normal old: education matters

This study examined whether the severity of cerebral white matter abnormalities (evident on MR images as white matter hyperintensities (WMH)) was related to the cognitive performance of 141 high-functioning older adults. The elderly showed the typical age decrement on measures of processing speed, working memory, and inhibition; however WMH severity was significantly related only to processing speed. The strength of this relationship was, however, influenced by the educational level of the participants, such that processing speed was more associated with WMH severity in less-educated than in well-educated participants. This is consistent with recent concepts of cognitive reserve, but does raise a question as to the underlying source of the cognitive decrement found in the sort of well-educated elders typically used in cognitive-aging studies.     

Sacred images in dreamwork: The journey into self as journey into God

In adults, it is proposed that psychospiritual development occurs concurrently with a shift in god-image. Dreams provide primary access to discover and study this shift. Midlife graduate students in Pastoral Counseling and Spiritual Development each submitted a dream in a group seminar format. Images and themes that emerged reflect the individuation process described by C. G. Jung: the archetypal journey of life, the descent into hell, and the inner marriage were themes that recurred. This paper includes examples of dream material suggesting various sacred images and discussion of the dreams as a call to ministry. Also presented are techniques for group dream work.     

Narcissism, Spiritual Pride, and Original Sin

Narcissism has roots in childhood and a broad impact on society. Parental abuse, neglect, or exploitation result in unmet emotional needs that leave low self-esteem and patterns of longing for affirmation. When these needs are not gratified, interpersonal conflict ensues. At the extreme, torture, wars, and other conflagrations can be seen to have roots in narcissism, which is thus construed as the psychological explanation for what religion defines as original sin. The cold, dark pain of narcissistic woundedness comprises an abyss in the soul. Spiritual resources, including mysticism and surrender to divine love, may offer deep healing for those wounds.     

The rise of the nones and the changing relationships between identity,belief, and behavior

ABSTRACT

One of the more remarkable trends of the past 30 years is the dramatic rise of individuals who do not identify with any religious tradition. While this trend has been well documented, some of the underlying dynamics and consequences have not been fully appreciated or explicated. We examine the General Social Survey in the period from 1972 to 2014 to examine how the increase in the ‘nones’ is tied to changes in the strength of religious identity among US adults and, in turn, how the rise of the nones has affected the relationships between religious identity, religious belief, and religious behavior. In particular, we show that, as the percentage of US adults who do not identify with a religion has grown, the correlations between religious identification, belief, and behavior have increased. In short, the rise of the nones has led to more congruence between measures of religion.     

Visuospatial Neglect: The Ultimate Deconstruction?

Unilateral visuospatial neglect is now widely acknowledged to be a highly heterogeneous condition: The overt manifestations of visual neglect can vary as a function of task, spatial domain, and mode of response (at least). Double dissociations (sometimes of the strong form) have already been reported between most of the components of what was originally thought to be a relatively stable construct within the visual modality. Nonetheless, throughout successive fractionations of neglect, reported cases of bidirectional task-specific neglect after unilateral brain damage are rare. We now report two such cases. After right hemisphere stroke, the first patient reliably showed severe left neglect on cancellation but right neglect on line bisection. After left hemisphere stroke, the second case showed right neglect on cancellation but left neglect on line bisection. Extensive investigation of case 1 confirmed our previous conjecture that the crucial distinction between these tasks lies in the presence or the absence of an overt target. In contrast to cancellation, line bisection demands the internal computation of the location of the “target” (the midpoint), followed by executing a motor response toward the precise location of that “imaginary” midpoint. The relative attentional and premotor contributions of the intact and damaged hemispheres to these forms of bidirectional neglect are also assessed.     

Influence of age and sex on line bisection: a study of normal performance with implications for visuospatial neglect

Line bisection is an established clinical task used to diagnose visuospatial neglect. To date, few studies have considered the extent to which age and sex as background variables contribute to bisection performance. Both variables affect the neural substrates underlying cognitive processes and hence the behavioural performance of bisection. The purpose of this study was to examine the effects of age and sex on normal bisection performance, using three different line lengths to elucidate the influence of these potential contributing factors. Seventy men and 70 women, divided equally into seven age-cohorts between 14 and 80 years, bisected lines. Results indicated clear age- and sex-related differences both in the magnitude and direction of bisection deviations across the three line lengths. Differences are discussed in terms of neural changes across the adult lifespan including hemispheric differences and hormonally mediated changes.     

Alzheimer's Disease Does Not Selectively Impair Decisions About Word Meaning

Patients with probable Alzheimer's disease (AD) and normal young and older participants were asked to make decisions about the orthography, phonology and semantics of visually presented stimulus words. Whereas AD patients were slower than normals in making decisions, there was no evidence that they were any more impaired in making one type of decision than another. Specifically, they did not show a disproportionate slowing for decisions requiring access to word meaning. These results are not consistent with a degradation of semantic knowledge in AD, but rather suggest the presence of a relatively generalized slowing of information processing.     

Extinction of Within-event Learning Is Contextually Controlled and Subject to Renewal

Five experiments examined within-event learning in rats by inducing an appetite for one of the elements (salt) of a compound stimulus and assessing preference for the other element (almond). Almond preference was conditional upon (1) the almond flavour having been presented in compound with the salt, and (2) the assessment being conducted when the rats were out of sodium balance (Experiment 1). Presentations of the compound in one environment (A) and of the salt and almond elements in a second environment (B) resulted in greater almond preference when rats were tested in A than in B (Experiment 2). Almond preference was reduced when separate presentations of the compound and almond (Experiment 3) or of the compound and salt (Experiment 4) occurred in the same environments but not when these presentations occurred in different environments. Rats exposed to the compound in A and then extinguished to the elements in either A or B showed a reduced almond preference when tested in the extinction environment, but not when tested in the other environment (Experiment 5). Thus, extinction of within-event learning is context-specific and subject to renewal. The results were interpreted in terms of an associative model whereby separate presentations of the elements result in a symmetrical inhibitory link which is contextually gated (Bouton, 1993).
