An evaluation of simultaneous and sequential presentation of preferred and nonpreferred food to treat food selectivity

In the current investigation, we compared two methods of food presentation (simultaneous vs. sequential) to increase consumption of nonpreferred food for 3 children with food selectivity. In the simultaneous condition, preferred foods were presented at the same time as nonpreferred food (e.g., a piece of broccoli was presented on a chip). In the sequential condition, acceptance of the nonpreferred food resulted in presentation of the preferred food. Increases in consumption occurred immediately during the simultaneous condition for 2 of the 3 participants. For 1 participant, increases in consumption occurred in the simultaneous condition relative to the sequential condition, but only after physical guidance and re-presentation were added to treatment. Finally, consumption increased for 1 participant in the sequential condition, but only after several sessions. These results are discussed in terms of possible mechanisms that may alter preferences for food (i.e., establishing operations, flavor-flavor conditioning).     

Longing for Life Extension: Science Fiction and Late Life

Rejuvenescence has long been a topic of legend and medicine. As the body became the property of medical science, speculative fiction asked how fantastic experiments with bodies would affect the life course. In science fiction, medical breakthroughs promise or threaten to forestall or even reverse the decline from midlife through old age to senility and decrepitude. Responding to debates over evolution, eugenics, and scientific experimentation with human and animal subjects, rejuvenescence novels such as Bruce Sterling's Holy Fire (1996) ask readers whether they desire long life or heightened quality of life; the consolations of age or the hungers of youth; short-lived intensity or perpetual ennui.     

The Late Life Reconstruction of Selfhood Analyzed in Peter Hall's Film She's Been Away

The film She's Been Away tells the story of an old woman who had been locked in a mental asylum while a teenager, for willfully violating repressive sexual codes. Sixty years later her ward is closed and she moves in with her nephew and his wife. Faced with what appears to be a hopeless situation, she manages to forge a sense of a meaningful closure to a misspent life. Through narrative, story structure, and characterization the film throws into focus coping mechanisms and ego strategies deployed by a triple disadvantaged person (woman, old, and mad) in her ascent to a reconstructed selfhood. As the protagonist ties both ends of her life, and faces the abyss in between she makes genuine adaptive use of so-called regressive, late-life development assets (available to a lesser degree to elderly people in normal life circumstances), primarily the abolition of linear time. Through this abolition she makes reminiscing an actual reality while still maintaining a functional separation between the real and the remembered. Her portrayal is a valuable document for gerontologists as it explores, through artistic imagination and intuition, the workings of an aging mind in search for a meaningful sense of closure.     

Pessimism

The problem of pessimism is the secular analogue to the evidential problem of evil facing traditional theism. The traditional theist must argue two things: that the evidence shows that this is on balance a good world and that it is the best possible world. Though the secular optimist who advocates any form of secular moral theory need not argue that the current and future world will likely be the best possible world, she nonetheless must argue that were there a clean solution to the problem of current and future suffering in which all sentient life could be instantly and painlessly eliminated, we would have reasons not to employ the clean solution because the future promises to bring on balance a good world in which the evil of human and animal suffering is outweighed by whatever is good in the world. Pessimism is the view that the evidence argues against secular optimism. It is argued here that it is anything but clear that secular optimism is warranted when viewed from an impersonal point of view. The problem is then evaluated from the personal point of view in which a form of personal optimism is defended even in the face of impersonal pessimism.     

Pace of Life and Enjoyment of Life

The paper addresses the paradox that people in modern societies believe themselves to be very happy and satisfied with their lives while simultaneously are subjected to increasing time pressure and pace of life. It starts with presenting evidence for time pressure covering objective and subjective indicators. Evidence for Germany is given by comparing time-budgets in 1991/92 and in 1999. Time use among full time employed in Germany and other EU-societies in the 1990s is compared to the US and Japan by means of diary-data. As regards work life, overwork and the gap between actual and preferred working hours are examined. Survey-results on the relationship between work load, time pressure, stress and health are reported.Most of these data support the conclusion that time pressure has emerged as a major social problem. Hence citizens are beginning to consider time prosperity as a dimension of their well-being beyond their consumer wealth.However, this growing pace of life does not reduce life satisfaction and happiness. Here a paradox evolves as increasing time pressure goes hand in hand with increased subjective well-being (SWB) at country level in cross-cultural comparison as well as at individual level.In the third section some answers to this paradox are explored: A first answer is offered through the modernization theory: life satisfaction and QOL are proliferating along with economic growth and living standards. This process at the same time accelerates social life. Hence, the negative effects of time pressure are counterbalanced by various yields of the modernization process resulting in a pattern of "heavy-going" satisfaction.A second explanation is the psychological approach: time pressure fulfils positive functions for mobilizing individual resources. A variation of this argument is that the multiple-choice-society offers a wide variety of attractive options resulting in people engaging in too many activities. Here, the enjoyment of life is equated with taking advantage of every opportunity.However, this paper prefers a third approach based on Simmel's explanation of the ambivalent consequences of modernity. Even where the majority of citizens report high levels of happiness and life satisfaction – which can be explained through "arousal" or "eu-stress" – the need to ease the time-burden of disadvantaged groups and to down-speed work and social life in general is essential.     

Religion and the Quality of Life

Subjective and objective indicators of the quality of life (QOL) are used to test relationships with religious involvement, participation, and belief. Findings from other studies show religious involvement to be associated with longer life. The percent of religious adherents in a state is correlated with the harmony domain of the QOL and negatively with an indicator of stress. After reviewing relevant previous studies, I examine data from the 1972–1996 General Social Survey Cumulative File. It shows happiness to be associated with the frequency of attendance at religious services, with denominational preference, and with doctrinal preference. Happiness also is associated with certain religious-related beliefs: belief that the world is evil or good but not belief in immortality. In a discussion of these and other findings, hypotheses are suggested to explain and to further explore the effects of religion upon the QOL. Among the conclusions: our conception of the "good life" rests heavily upon Judeo-Christian ideals; religious organizations contribute to the integration of the community, hence enhancing the QOL; since frequency of attendance is imperfectly associated with the QOL, other influences are at work; the doctrine of the religion may attract persons of happy disposition; religion may explain a purpose in life that fosters well-being; and others. I suggest implications of the findings for programs of religious organizations.     

Timeout postponement without increased reinforcement frequency

Three experiments were conducted to examine pigeons' postponement of signaled extinction periods (timeouts) from a schedule of food reinforcement when such responding neither decreased overall timeout frequency nor increased the overall frequency of food reinforcement. A discrete-trial procedure was used in which a response during the first 5 s of a trial postponed an otherwise immediate 60-s timeout to a later part of that same trial but had no effect on whether the timeout occurred. During time-in periods, responses on a second key produced food according to a random-interval 20-s schedule. In Experiment 1, the response-timeout interval was 45 s under postponement conditions and 0 s under extinction conditions (responses were ineffective in postponing timeouts). The percentage of trials with a response was consistently high when the timeout-postponement contingency was in effect and decreased to low levels when it was discontinued under extinction conditions. In Experiment 2, the response-timeout interval was also 45 s but postponement responses increased the duration of the timeout, which varied from 60 s to 105 s across conditions. Postponement responding was maintained, generally at high levels, at all timeout durations, despite sometimes large decreases in the overall frequency of food reinforcement. In Experiment 3, timeout duration was held constant at 60 s while the response-timeout interval was varied systematically across conditions from 0 s to 45 s. Postponement responding was maintained under all conditions in which the response-timeout interval exceeded 0 s (the timeout interval in the absence of a response). In some conditions of Experiment 3, which were designed to control for the immediacy of food reinforcement and food-correlated (time-in) stimuli, responding postponed timeout but the timeout was delayed whether a response occurred or not. Responding was maintained for 2 of 3 subjects, suggesting that behavior was negatively reinforced by timeout postponement rather than positively reinforced by the more immediate presentation of food or food-correlated (time-in) stimuli.     

Global Progress I: Empirical Evidence for ongoing Increase in Quality-of-life

This paper argues that both the relativist and the pessimist critiques of the idea of progress are inadequate. Progress is defined as increase in global quality of life (QOL). Such QOL is intrinsically subjective, but not relative. It can be reliably measured through life satisfaction-type questions. The World Database of Happiness provides extensive data on social, economic and psychological factors that correlate with overall QOL. They include wealth, health, security, knowledge, freedom and equality. Various statistical data suggest that all these QOL indicators have undergone significant improvements during the last half century, in most of the world. This gives strong support to the thesis that progress objectively occurs.     

Selection and inhibition in infancy: evidence from the spatial negative priming paradigm

We used a spatial negative priming (SNP) paradigm to examine visual selective attention in infants and adults using eye movements as the motor selection measure. In SNP, when a previously ignored location becomes the target to be selected, responses to it are impaired, providing a measure of inhibitory selection. Each trial consisted of a prime and a probe, separated by 67, 200, or 550 ms interstimulus intervals (ISIs). In the prime, a target was accompanied by a distractor. In the probe, the target appeared either in the location formerly occupied by the distractor (ignored repetition) or in another location (control). Adults exhibited the SNP effect in all three ISI conditions, producing slower saccade latencies on ignored repetition versus control trials. The SNP effect obtained for infants only under 550 and 200 ms ISI conditions. These results suggest that important developments in visual selection are rooted in emerging inhibitory mechanisms.     

Hope,Social Support,and Postpartum Depression: Disentangling the Mediating Effects of Negative Affectivity

We examined the potentially mediating effects of negative affectivity (NA) on the hope–depression relationship among a sample of postpartum women. We also assessed the social support reported by these women and examined the possible mediating effects of NA on the social support–postpartum depression relationship. Correlational analyses of data obtained from women (N = 98) who had given birth in the previous 6 months revealed that NA did not mediate either hope or social support in the prediction of postpartum depression. Hope accounted for a significant degree of variance in postpartum depression. These data suggest that hope has palliative effects among women following childbirth and these effects are not nullified or explained by emotional predispositions.
