Early Cognitive Decline and Its Impact On Spouse’s Loneliness

Loneliness is common in dementia caregivers as cognitive impairment (CI) alters marital and social relationships. Unexplored is how an individual’s loneliness is affected at earlier, more ambiguous, periods of their spouse’s CI. Using the Health and Retirement Study, our study participants included 2,206 coupled individuals with normal cognitive function at the 2006/8 baseline. Loneliness outcomes at baseline, 4-year, and 8-year follow-up are assessed by the status of transition to cognitive impairment no dementia (TCIND) (2010/12 & 2014/16) using linear mixed models. Individual’s loneliness was stable when their spouse’s cognition remained normal, but increased with the spouse’s TCIND. The increase in loneliness did not vary by gender. Loneliness, a key risk factor for reduced life quality and increased depression, increases even at early stages of a partner’s CIND. This work suggests the potential impact of early intervention and social support for partners of individuals with CIND.     

The Visible Christ and the Invisible Trinity: MT. 5:8 in Augustine's Trinitarian Theology of 400

The essay is an analysis of Augustine's solution to what I identify as the Homoian subordinationist understanding of the Son's visibility. This solution lies in Augustine's (re-)interpretation of Old Testament theophanies, and his doctrine of the vision through Christ of the Trinity at the end-time which Augustine supports by an exegesis of Mt. 5:8. Historically, the issue for Augustine is the connection made between doctrines of the Son's inherent "visibility" before the Incarnation and arguments made both against modalism and in support of subordinationism on the basis of that visibility. For Augustine's own Trinitarian theology, any consideration of a sight or vision of God in, e.g., Old Testament theophanies or the Incarnation necessarily raises questions about "sight" as both sensible and noetic knowledge, the structure of our way(s) of knowing, and the role of faith as the means for purifying the knowing capacity in humanity. The question of the vision of God which Augustine addresses in those early books of de Trinitate which are written around the year four hundred is connected to Augustine's epistemological concerns addressed in a variety of writings written before or contemporary to books I-IV of de Trinitate .

Early modulation of visual input: A study of attentional strategies

Despite agreement among many attentional theories that processing resources are limited and allocated according to task demands, controversy continues about the locus of selectivity. Studies of spatial orientation of attention suggest an early effect. These results, however, can be explained instead by effects of decision processes. The present study avoids this difficulty by directly manipulating attention in a dual-task paradigm and by using SDT to dissociate sensory tuning from criterion shifts. Ten subjects judged whether two lines to the left of fixation were the same or different in length; they also judged two lines presented simultaneously to the right. In a given block of 64 trials, the subject was to allocate 80%, 50%, or 20% of attention to one pair of lines and the rest to the other. On every trial, the subject judged both pairs. Results showed that d' increased from 0.77 with 20% allocation to 1.69 with 80%, indicating that sensitivity is modulated by attentional instructions. These results are predicted quantitatively by Luce's sample-size model.     

Association between adolescent rough-and-tumble play and conduct problems,substance use,and risk-taking behaviors: Findings from a school-based sample

Rough-and-tumble play (RTP), also known as play fighting, is a common form of play frequently reported and studied by researchers. However, one important limitation of past research in the area of RTP has been the neglect of the adolescence period. Consequently, little is known about the function of adolescent RTP as well as about clinical characteristics of youth who engage in this activity after childhood. In a school-based sample of 1,771 middle school students (ages 9–16 years), the current study sought to address this gap by examining, via bivariate and multivariate logistic regression analyses, the potential cross-sectional associations of adolescent RTP with (a) selected demographic variables, (b) conduct problem symptoms, (c) substance use, and (d) risk-taking behaviors, including adjustment for several demographic confounders. Results indicated that adolescents reporting higher rates of conduct problem symptoms were more likely to report a recent participation in RTP. In addition, substance use (experimentation and current consumption of tobacco, alcohol, and marijuana) and risk behaviors assessed all were strongly associated with an increased likelihood of reporting an engagement in RTP. This finding suggests that participation in this activity probably implicates particular phenotypic characteristics including the propensity to engage in health-damaging behaviors. But the most profound issue raised by this research concerns the strong relationship between RTP and great levels of conduct disorder symptoms, suggesting a possible significant change in the functional significance of RTP in the adolescence period.     

Algorithmic solution of arithmetic problems and operands-answer associations in long-term memory

Many developmental models of arithmetic problem solving assume that any algorithmic solution of a given problem results in an association of the two operands and the answer in memory (Logan & Klapp, 1991; Siegler, 1996). In this experiment, adults had to perform either an operation or a comparison on the same pairs of two-digit numbers and then a recognition task. It is shown that unlike comparisons, the algorithmic solution of operations impairs the recognition of operands in adults. Thus, the postulate of a necessary and automatic storage of operands-answer associations in memory when young children solve additions by algorithmic strategies needs to be qualified.     

Head and eye movements affect object processing in 4‐month‐old infants more than an artificial orientation cue

This study investigates the effects of attention‐guiding stimuli on 4‐month‐old infants' object processing. In the human head condition, infants saw a person turning her head and eye gaze towards or away from objects. When presented with the objects again, infants showed increased attention in terms of longer looking time measured by eye tracking and an increased Nc amplitude measured by event‐related potentials (ERP) for the previously uncued objects versus the cued objects. This suggests that the uncued objects were previously processed less effectively and appeared more novel to the infants. In a second condition, a car instead of a human head turned towards or away from objects. Eye‐tracking results did not reveal any significant difference in infants' looking time. ERPs indicated only a marginally significant effect in late slow‐wave activity associated with memory encoding for the uncued objects. We conclude that human head orientation and gaze direction affect infants' object‐directed attention, whereas movement and orientation of a car have only limited influence on infants' object processing.
