Change in coping and defense mechanisms across adulthood: Longitudinal findings in a European American sample.
This study examined longitudinal changes in coping and defense mechanisms in an age- and gender-stratified sample of 392 European-American adults. Nonlinear age-related changes were found for the coping mechanisms of sublimation and suppression and the defense mechanisms of intellectualization, doubt, displacement, and regression. The change trajectories for sublimation and suppression showed that their use increased from adolescence to late middle age and early old age, and remained mostly stable into late old age. The change trajectory for intellectualization showed that the use of this defense mechanism increased from adolescence to middle age, remained stable until late midlife, and started to decline thereafter. The defense mechanisms of doubt, displacement, and regression showed decreases from adolescence until early old age, with increases occurring again after the age of 65. Linear age-related decreases were found for the coping mechanism of ego regression and the defense mechanisms of isolation and rationalization. Gender and socioeconomic status were associated with the mean levels of several coping and defense mechanisms, but did not moderate age-related changes. Increases in ego level were associated with increased use of the defense mechanism intellectualization and decreased use of the defense mechanisms of doubt and displacement. Overall, these findings in a European-American sample suggest that most individuals showed development in the direction of more adaptive and less maladaptive coping and defense strategies from adolescence until late middle age or early old age. However, in late old age this development was reversed, presenting potential challenges to the adaptive capacity of older adults
The Misprediction of emotions in Track Athletics.: Is experience the teacher of all things?
People commonly overestimate the intensity of their emotions toward future events. In other words, they display an impact bias. This research addresses the question whether people learn from their experiences and correct for the impact bias. We hypothesize that athletes display an impact bias and, counterintuitively, that increased experience with an event increases this impact bias. A field study in the context of competitive track athletics supported our hypotheses by showing that athletes clearly overestimated their emotions toward the outcome of a track event and that this impact bias was more pronounced for negative events than for positive events. Moreover, with increased athletic experience this impact bias became larger. This effect could not be explained by athletesâ forecasted emotions, but it could be explained by the emotions they actually felt following the race. The more experience athletes had with athletics, the less they felt negative emotions after unsuccessful goal attainment. These findings are discussed in relation to possible underlying emotion regulation processes
Spatio-temporal Fermionization of Strongly Interacting 1D Bosons
Building on the recent experimental achievements obtained with scanning
electron microscopy on ultracold atoms, we study one-dimensional Bose gases in
the crossover between the weakly (quasi-condensate) and the strongly
interacting (Tonks-Girardeau) regime. We measure the temporal two-particle
correlation function and compare it with calculations performed using the Time
Evolving Block Decimation algorithm. More pronounced antibunching is observed
when entering the more strongly interacting regime. Even though this mimics the
onset of a fermionic behavior, we highlight that the exact and simple duality
between 1D bosons and fermions does not hold when such dynamical response is
probed. The onset of fermionization is also reflected in the density
distribution, which we measure \emph{in situ} to extract the relevant
parameters and to identify the different regimes. Our results show agreement
between experiment and theory and give new insight into the dynamics of
strongly correlated many-body systems

Thinking about a limited future enhances the positivity of younger and older adultsâ recall: support for socioemotional selectivity theory
Compared with younger adults, older adults have a relative preference to attend to and remember positive over negative information. This is known as the âpositivity effect,â and researchers have typically evoked socioemotional selectivity theory to explain it. According to socioemotional selectivity theory, as people get older they begin to perceive their time left in life as more limited. These reduced time horizons prompt older adults to prioritize achieving emotional gratification and thus exhibit increased positivity in attention and recall. Although this is the most commonly cited explanation of the positivity effect, there is currently a lack of clear experimental evidence demonstrating a link between time horizons and positivity. The goal of the current research was to address this issue. In two separate experiments, we asked participants to complete a writing activity, which directed them to think of time as being either limited or expansive (Experiments 1 and 2) or did not orient them to think about time in a particular manner (Experiment 2). Participants were then shown a series of emotional pictures, which they subsequently tried to recall. Results from both studies showed that regardless of chronological age, thinking about a limited future enhanced the relative positivity of participantsâ recall. Furthermore, the results of Experiment 2 showed that this effect was not driven by changes in mood. Thus, the fact that older adultsâ recall is typically more positive than younger adultsâ recall may index naturally shifting time horizons and goals with age
Quantum transport in ultracold atoms
Ultracold atoms confined by engineered magnetic or optical potentials are
ideal systems for studying phenomena otherwise difficult to realize or probe in
the solid state because their atomic interaction strength, number of species,
density, and geometry can be independently controlled. This review focuses on
quantum transport phenomena in atomic gases that mirror and oftentimes either
better elucidate or show fundamental differences with those observed in
mesoscopic and nanoscopic systems. We discuss significant progress in
performing transport experiments in atomic gases, contrast similarities and
differences between transport in cold atoms and in condensed matter systems,
and survey inspiring theoretical predictions that are difficult to verify in
conventional setups. These results further demonstrate the versatility offered
by atomic systems in the study of nonequilibrium phenomena and their promise
for novel applications.Comment: 24 pages, 7 figures. A revie

The effects of multi-domain versus single-domain cognitive training in non-demented older people: a randomized controlled trial
<p>Abstract</p> <p>Background</p> <p>Whether healthy older people can benefit from cognitive training (CogTr) remains controversial. This study explored the benefits of CogTr in community dwelling, healthy, older adults and compared the effects of single-domain with multi-domain CogTr interventions.</p> <p>Methods</p> <p>A randomized, controlled, 3-month trial of CogTr with double-blind assessments at baseline and immediate, 6-month and 12-month follow-up after training completion was conducted. A total of 270 healthy Chinese older people, 65 to 75 years old, were recruited from the Ganquan-area community in Shanghai. Participants were randomly assigned to three groups: multi-domain CogTr, single-domain CogTr, and a wait-list control group. Twenty-four sessions of CogTr were administrated to the intervention groups over a three-month period. Six months later, three booster training sessions were offered to 60% of the initial training participants. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS, Form A), the Color Word Stroop test (CWST), the Visual Reasoning test and the Trail Making test (TMT) were used to assess cognitive function.</p> <p>Results</p> <p>Multi-domain CogTr produced statistically significant training effects on RBANS, visual reasoning, and immediate and delayed memory, while single-domain CogTr showed training effects on RBANS, visual reasoning, word interference, and visuospatial/constructional score (all <it>P </it>< 0.05). At the 12-month posttest, the multi-domain CogTr showed training effects on RBANS, delayed memory and visual reasoning, while single-domain CogTr only showed effects on word interference. Booster training resulted in effects on RBANS, visual reasoning, time of trail making test, and visuospatial/constructional index score.</p> <p>Conclusions</p> <p>Cognitive training can improve memory, visual reasoning, visuospatial construction, attention and neuropsychological status in community-living older people and can help maintain their functioning over time. Multi-domain CogTr enhanced memory proficiency, while single-domain CogTr augmented visuospatial/constructional and attention abilities. Multi-domain CogTr had more advantages in training effect maintenance.</p> <p>Clinical Trial Registration</p> <p>Chinese Clinical Trial Registry. Registration number: ChiCTR-TRC-09000732.</p
Effects of parental imprisonment on child antisocial behaviour and mental health: a systematic review
Parental imprisonment can cause many problems for the family left behind,
including difficulty organising childcare, loss of family income, trouble maintaining
contact with the imprisoned parent, stigma, and home, school and neighbourhood
moves. Children and parents can be distressed by the separation. Children may
respond by acting out or becoming withdrawn, anxious or depressed. We conducted
an exhaustive search for studies that examined children's antisocial behaviour and
mental health after parental imprisonment. We found 16 studies with appropriate
evidence. These studies all showed that children of prisoners are more likely than
other children to show antisocial and mental health problems. However, it was
unclear whether parental imprisonment actually caused these problems. They might
have been caused by other disadvantages in children's lives that existed before
parental imprisonment occurred. Children of prisoners are a vulnerable group. More
research is required to determine whether or not parental imprisonment causes an
increase in child antisocial behaviour and mental health problems
