Ageing, by definition, involves moving across lived time. Grounded in developmental psychology, particularly lifespan developmental theory, this study examines two time-related factors that may affect psychological wellbeing in adulthood. Particularly, chronological age and perceived time left to live (i.e. future time perspective) are predicted to act as opposing forces in the construction of psychological wellbeing. Young (N = 285, 19–29 years) and middle-aged adults (N = 135, 47–64 years) self-reported their current psychological wellbeing (across six dimensions) and their sense of future time perspective. As predicted, mediation analyses show that higher levels of chronological age (being in midlife), and having a more open-ended, positive future time perspective are both related to higher psychological wellbeing. Note, however, that being in midlife is related to a more limited and negative future time perspective. As such, confirming our conceptual argument, while both age and future perspective are measures of time in a general sense, analyses show that they act as unique, opposing forces in the construction of psychological wellbeing. The current research suggests that individuals can optimise psychological wellbeing to the extent that they maintain an open-ended and positive sense of the future.

Patterns of cerebral asymmetry related to visuospatial functions may change with age. The typical leftward bias on a line bisection task may reflect cerebral asymmetry. With age, such leftward bias decreases. This study demonstrated that the age-related decrease of leftward bias may actually be sex-specific. In addition, previous research suggests that young adults’ deviation in line bisection may reflect asymmetric hemispheric activation of perceptual–attentional “where” spatial systems, rather than motor-intentional “aiming” spatial systems; thus, we specifically fractionated “where” and “aiming” bias of men and women ranging in age from 22 to 93 years old. We observed that older men produced greater rightward line bisection errors, of primarily “where” spatial character. However, women's errors remained leftward biased, and did not significantly change with age. “Where” spatial systems may be linked to cortico-cortical processing networks involving the posterior part of the dorsal visuospatial processing stream. Thus, the current results are consistent with the conclusion that reduced right dorsal spatial activity in aging may occur in the male, but not female, adult spatial system development.

The aim of the present investigation was to determine whether differences in the strength of original information influence adult age differences in susceptibility to misinformation. One-half of the younger and older adults watched a slide sequence once (one-trial learning) that depicted a theft, whereas the remaining participants viewed the slide sequence repeatedly to ensure that all critical details were encoded (criterion learning). Three weeks later and immediately prior to final testing, participants were asked questions that contained misleading information. As expected, the degree of initial learning influenced age differences in misinformation reporting. That is, when event memory was poorer for older than younger adults (in the criterion learning condition), older adults were more susceptible to misinformation than younger adults. However, when memory of the event was poor (in the one-trial learning condition), the younger adults reported more misled details than the older adults, possibly because the younger adults had better memory for the misleading information. Therefore, strength of initial memory influences the extent and direction of adult suggestibility and helps explain the discrepancy found across studies in this area.

Psychological distress in cancer patients is inversely related to age, although the reasons are unclear. The adult development literature suggests that ageing may be associated with the development of adaptive capacities, specifically greater attachment security (the sense that others will be available and supportive when needed) and spirituality (the capacity to view one's life as having meaning, purpose and value), that enable older people to cope better with disease. We examined whether age-related patterns in attachment security and spiritual wellbeing account for the protective effect of age against distress. Measures of depression, attachment security, spiritual wellbeing and disease burden were collected from 342 patients aged from 21 to 88 years with advanced, metastatic cancer. Attachment security and spiritual wellbeing were tested as mediators of the effect of age on depression, controlling for disease burden. It was found that age was associated inversely with depression and positively with spiritual wellbeing and attachment security. Depression was inversely related to attachment security and spiritual wellbeing, and the effect of age on depression was fully mediated by attachment security and spiritual wellbeing. The relative protection from psychological distress among older cancer patients may be the result of age-related developmental accomplishments and/or differences in the response to adverse life-events.

The comparative development of Echinococcus multilocularis was studied in its definitive hosts, the fox, dog, cat and raccoon dog, beyond the pre-patent period to 90 days post-infection. All host species, apart from cats were susceptible to infection and capable of supporting substantial worm burdens. Although worms in cats matured and produced thick-shelled eggs, their overall development was retarded compared to that in other species in which the parasite matured rapidly producing large populations of gravid worms. E. multilocularis matured rapidly in foxes and raccoon dogs and this was sustained in raccoon dogs but not in foxes in which maturation of worms declined during the later stages of infection, in contrast to that in both raccoon dogs and dogs. These populations were sustained for longer in raccoon dogs and dogs compared to foxes. Cats would appear to have only a minor role in the maintenance of E. multilocularis in endemic areas, and infections in cats may be of minimal public health significance. In contrast, foxes, dogs and the recently recognized definitive host the raccoon dog, are all capable of playing significant roles in the epidemiology of alveolar echinococcosis. This study also demonstrated that the developmental processes of growth, segmentation, proglottization and maturation in adult Echinococcus are independent and can be influenced by environmental factors thus confirming earlier in vitro observations.
