Why? Versus Why Not?: Potentialities of Aging in Shaw's Back to Methuselah

Bernard Shaw's critique of society's sacred cows, as well as his participation in the social, cultural and political marketplace in which he lived, resemble the new historical/cultural materialism of contemporary theory. In Back to Methuselah, Shaw examines the notions of aging and illuminates the degree to which our chronological standards of old age are sociological not biological constructs. This tour de force on aging both dramatizes age as a function of societal and/or individual choice, not as a biological given, and juxtaposes opinions toward aging in such a way that flexible attitudes toward the subject emerge.     

‘What the Devil a Woman Lives for After 30’: The Late Careers of Late Eighteenth-Century British Women Writers

This article begins to consider the late careers of late eighteenth-century English women writers. It provides a brief review of some of the eighteenth-century attitudes toward aging women and focuses specifically on the aging female writer. Surveying the available literature on this topic, the author demonstrates the need for a more thorough investigation of aging, gender, literary output, and reception among the first generations of professional women writers in Great Britain. This article concludes with a consideration of Hester Lynch Piozzi and some of her writing from her late years.     

Effect of Aging on Processes of Motor Inhibition

The processes of inhibiting uninstructed motor responses were examined to identify age differences. Younger adults (n = 40) and older adults (n = 38) participated in two experiments using the Stimulus‐Response Compatibility task. They were asked to push the switch on the side contralateral to the stimulus. The results indicated that responses induced by visual stimuli were gradually inhibited as a result of repeated trials on the contralateral (not‐induced) side, and no age differences were noted. The addition of a color‐discrimination task to the Stimulus‐Response Compatibility task inhibited impulsive response induced by visual stimuli in younger adults only. These results indicate that certain processes of inhibiting motor responses are affected by aging, whereas other processes remain unaffected.     

The effect of aging on the memory enhancement of the survival judgment task

This study investigated whether or not aging affected the benefit of a survival judgment task. Sixteen young adults and 16 older adults participated in this experiment. In the survival task, participants were requested to judge whether a word was necessary or not in a survival situation. In the self‐referent judgment task, participants were requested to judge how easily the word brings to mind an important personal experience. Participants in each condition were presented 18 concrete nouns at 4‐s intervals. Our results showed that even though the survival judgment task enhanced the memory performance in both the young adults and the older adults, the young adults outperformed the older adults in the survival and self‐referent judgment tasks.     

Color charts, esthetics, and subjective randomness

Color charts, or grids of evenly spaced multicolored dots or squares, appear in the work of modern artists and designers. Often the artist/designer distributes the many colors in a way that could be described as "random," that is, without an obvious pattern. We conduct a statistical analysis of 125 "random-looking" art and design color charts and show that they differ significantly from truly random color charts in the average distance between adjacent colors. We argue that this attribute generalizes results in subjective randomness in a black/white setting and gives further evidence supporting a connection between subjective randomness and what is esthetically pleasing.     

Hierarchical models of simple mechanisms underlying confidence in decision making

Choice confidence is a central measure in psychological decision research, often being reported on a probabilistic scale. Simple mechanisms that describe the psychological processes underlying choice confidence, including those based on error and confirmation biases, have typically received support via fits to data averaged over subjects. While averaged data ease model development, they can also destroy important aspects of the confidence data distribution. In this paper, we develop a hierarchical model of raw confidence judgments using the beta distribution, and we implement two simple confidence mechanisms within it. We use Bayesian methods to fit the hierarchical model to data from a two-alternative confidence experiment, and we use a variety of Bayesian tools to diagnose shortcomings of the simple mechanisms that are overlooked when applied to averaged data. Bugs code for estimating the models is also supplied.     

The canine sand maze: an appetitive spatial memory paradigm sensitive to age-related change in dogs

Aged dogs exhibit a spectrum of cognitive abilities including a syndrome similar to Alzheimer's disease. A major impediment to research so far has been the lack of a quick and accurate test of visuospatial memory appropriate for community-based animals. We therefore report on the development and validation of the Canine Sand Maze. A 4.5-m-diameter circular pool was filled with a sand and powdered food reward mix to a depth of 10 cm. Dogs were given 4 habituation and 16 learning trials which alternated a food reward being half (control trials) or fully-buried (acquisition trials) in a fixed location. After a 90-min break, a probe trial was conducted. Cognitively normal, aged (> 8 years, n = 11) and young (1-4 years, n = 11), breed-matched dogs were compared. After correction for differences in control trials, average probe times were 2.97 and 10.81 s for young and aged dogs, respectively. In the probe trial, both groups spent significantly more time in the target quadrant but there was a trend for young dogs to cross a 1 m(2) annulus zone around the buried reward more frequently (2.6 times) than aged dogs (1.5 times). Test-retest reliability in a subset of young dogs (n = 5) was high. On the basis of these findings, the Canine Sand Maze is presented as a quick, sensitive and nonaversive tool for assessing spatial learning and reference memory in dogs.     

The effects of romantic partners’ goal congruence on affective well-being

Affective well-being in romantic couples was examined from the perspective of interdependence theory. The independent variables were (a) presence of partner, (b) whether an activity met the actor’s goals, and (c) goals of the actor’s partner. Dependent variables were feelings of closeness and affective well-being (happiness, sadness, anger, anxiety). We predicted a three-way interaction with the highest affective well-being when partners are together and activities meet both partners’ goals. In Study 1, data from 194 married individuals who participated in an experience sampling study supported our predictions. Feelings of closeness partially mediated the effect on affective well-being. Study 2 replicated the findings with 112 participants in dating relationships who recalled specific events and made ratings about goals and affective well-being.     

Happy today, happy tomorrow: The (non-)effect of temporal distance on judgments of Life Satisfaction

Construal Level Theory (CLT; Trope &; Liberman, 2003) posits that everyday life predictions, evaluations, and choices are influenced by how near or distant in time the event is. However, judgments of Life Satisfaction (LS) are relatively weakly influenced by situational factors and relatively strongly influenced by personality factors. Moreover, the constructive episodic simulation hypothesis ( [Schacter and Addis, 2007] and [Schacter and Addis, 2007] ) implies that memory of past events provides details for simulations of future novel experiences. Undergraduate students (N = 127) were randomly asked for how desirable LS was and for actual judgements of LS in the near- or distant-future. The results show that LS was more desirable in the distant-future. Thus, indicating that LS is abstractly assessed and judgments of LS should therefore be influenced by temporal distance as predicted by CLT. However, no significant differences in actual LS were found between conditions. Implications for theory development are discussed.     

Commonly-defined and individually-defined posttraumatic growth in the US and Japan

Posttraumatic growth (PTG) is the experience of positive change resulting from the struggle with major life crises. Research on PTG has relied on instruments such as the Posttraumatic Growth Inventory (PTGI: Tedeschi &; Calhoun, 1996), in which items that describe positive changes are assumed to represent personal growth equally for all people. However, some positive changes may indicate greater growth for some people. Individually-defined PTG may differ from commonly-defined PTG. The purpose of this study was to explore the relationships between these two definitions of PTG and how culture affects them. Participants from the US (n = 456) and Japan (n = 279) indicated the degree to which each change in the PTGI represented personal growth. Results from mixed-model analyses of variance revealed that there were main effects for defined growth as well as interaction effects for all PTGI factors. For example, US participants reported greater growth on the factors Relating to Others and New Possibilities for the commonly-defined level, but once individually-defined PTG was considered, growth scores for US participants decreased substantially, and more so than for Japanese participants. Discussion addresses cultural and individual differences in the subjective definitions of PTG and highlights several directions for future research.
