The acceptance model of intuitive eating: a comparison of women in emerging adulthood, early adulthood, and middle adulthood

The acceptance model of intuitive eating (Avalos & Tylka, 2006) posits that body acceptance by others helps women appreciate their body and resist adopting an observer's perspective of their body, which contribute to their eating intuitively/adaptively. We extended this model by integrating body mass index (BMI) into its structure and investigating it with emerging (ages 18-25 years old, n = 318), early (ages 26-39 years old, n = 238), and middle (ages 40-65 years old, n = 245) adult women. Multiple-group analysis revealed that this model fit the data for all age groups. Body appreciation and resistance to adopt an observer's perspective mediated the body acceptance by others-intuitive eating link. Body acceptance by others mediated the social support-body appreciation and BMI-body appreciation links. Early and middle adult women had stronger negative BMI-body acceptance by others and BMI-intuitive eating relationships and a stronger positive body acceptance by others-body appreciation relationship than emerging adult women. Early adult women had a stronger positive resistance to adopt observer's perspective-body appreciation relationship than emerging and middle adult women.     

Age and age of acquisition: An evaluation of the cumulative frequency hypothesis

An important determinant of picture and word naming speed is the age at which the names were learned (age of acquisition). Two related interpretations of these effects are that they reflect differences between words in their cumulative frequency of use, or that they reflect differences in the amount of time early and lateacquired words have spent in lexical memory. Both theories predict that differences between early and late-acquired words will be less apparent in older than younger adults. Two experiments are reported in which younger and older adults read words varying in age of acquisition or frequency, or named objects varying in age of acquisition. There was an observed effect of word frequency only for young adults' word naming. In contrast, strong age of acquisition effects were found for both the young and the old participants. The implications of these results for theories of how age of acquisition might affect lexical processing are discussed.     

Do clever old people have earlier and richer first memories?

In a study of 377 people, from 54 to 83 years old, it was shown that the age of earliest memories was unrelated to current age but was related to intelligence. People with high IQ test scores remembered first and second memories at an earlier age than did those with lower IQ test scores. Intervals between first and second memories were briefer for those with high scores. The content of early memories was unrelated to age or intelligence.     

"You're only as old as you feel": self-perceptions of age, fears of aging, and life satisfaction from adolescence to old age

We examined differences in subjective age identification from adolescence to old age and the relation between subjective age and fears about one's own aging and life satisfaction. Using a questionnaire format, 188 men and women from 14 to 83 years of age made judgments about how old they felt, looked, acted, and desired to be. Respondents also answered questions about their personal fears of aging and present life satisfaction. Results revealed that individuals in their teens held older subjective age identities, whereas during the early adult years, individuals maintained same age identities. Across the middle and later adult years, individuals reported younger age identities, and women experienced younger age identities than men across these adults years. Results also revealed that discrepancies between subjective and actual age were associated with personal fears of aging and life satisfaction, especially in younger men and women.     

Reading strategy modulates parafoveal-on-foveal effects in sentence reading

Task demands and individual differences have been linked reliably to word skipping during reading. Such differences in fixation probability may imply a selection effect for multivariate analyses of eye-movement corpora if selection effects correlate with word properties of skipped words. For example, with fewer fixations on short and highly frequent words the power to detect parafoveal-on-foveal effects is reduced. We demonstrate that increasing the fixation probability on function words with a manipulation of the expected difficulty and frequency of questions reduces an age difference in skipping probability (i.e., old adults become comparable to young adults) and helps to uncover significant parafoveal-on-foveal effects in this group of old adults. We discuss implications for the comparison of results of eye-movement research based on multivariate analysis of corpus data with those from display-contingent manipulations of target words.     

Preschoolers affect others' reputations through prosocial gossip

Providing evaluative information to others about absent third parties helps them to identify cooperators and avoid cheaters. Here, we show that 5‐year‐olds, but not 3‐year‐olds, reliably engage in such prosocial gossip. In an experimental setting, 5‐year‐old children spontaneously offered relevant reputational information to guide a peer towards a cooperative partner. Three‐year‐old children offered such evaluative information only rarely, although they still showed a willingness to inform in a non‐evaluative manner. A follow‐up study revealed that one component involved in this age difference is children's developing ability to provide justifications. The current results extend previous work on young children's tendency to manage their own reputation by showing that preschoolers also influence others' reputations via gossip.     

Early motor development and cognitive abilities among Mexican preschoolers

Psychomotricity plays a very important role in children’s development, especially for learning involving reading–writing and mathematical calculations. Evaluate motor development in children 3 years old and its relationship with their cognitive abilities at the age of 5 years. Based on a cohort study, we analyzed the information about motor performance evaluated at 3 years old by Peabody Motor Scale and cognitive abilities at 5 years old. The association was estimated using linear regression models adjusted by mother’s intelligence quotient, sex, Bayley mental development index at 18 months, and quality of the environment at home (HOME scale). 148 children whose motor performance was determined at age 3 and was evaluated later at age 5 to determine their cognitive abilities. Cognitive abilities (verbal, quantitative, and memory) measured by McCarthy Scales. Significant positive associations were observed between stationary balance at age 3 with verbal abilities (β = 0.67, p = .04) and memory (β = 0.81, p = .02) at 5 years. Grasping and visual-motor integration were significant and positively associated with quantitative abilities (β = 0.74, p = .005; β = 0.61, p = .01) and memory (β = 2.11, p = .001; β = 1.74, p = .004). The results suggest that early motor performance contributes to the establishment of cognitive abilities at 5 years. Evaluation and early motor stimulation before the child is faced with formal learning likely helps to create neuronal networks that facilitate the acquisition of academic knowledge.     

Long Lives and Old Age Poverty: Social Stratification and Life-Course Institutionalization in Switzerland

This article combines an inter- and an intra-cohort perspective to study economic vulnerability in old age. The theoretical background is given through the combination of a social stratification framework and an institutional perspective emphasizing life course policies. At the macro level, the increase in overall education levels and the implementation of a pension system were the driving forces of the strong decrease in old age poverty over the last three decades. At an individual level, the pathway from low education early in life to economic hardship after retirement is most prominent, corresponding to a social stratification and cumulative disadvantage view.     

心理时间旅行与自我:发展中关系模式的转换

该研究分别考察了儿童中晚期(9~12岁)、少年期(13~15岁)和青年早期(17岁、19岁、21岁)个体心理时间旅行的发展模式,并进一步探讨了不同年龄阶段,情景记忆和自我对情景预见作用模式的转换。研究采用访谈法评估心理时间旅行,以自我描述(儿童期和少年期)或自我连续性(青年早期)作为评估自我的指标。研究发现:(1)儿童中晚期,想象未来情景细节的数量随年龄增长而增加,少年期和青年早期的情景预见能力则趋于平稳,与情景记忆的发展趋势一致;(2)无论在哪个年龄段,情景记忆对情景预见都是有效的预测源;(3)自我描述在少年期才开始对情景预见产生预测作用;(4)青年早期,情景记忆以自我连续性为中介变量作用于情景预见。     

Gratitude From Early Adulthood to Old Age

Are there age differences in gratitude from early adulthood to old age? The current studies tested several ways by which an association between age and dispositional gratitude may present, by considering multiple measures on both fronts. We used data from three cross‐sectional studies (total N = 1,736; total age range: 19–94). The results indicated that (a) age effects in gratitude are more likely to occur for subjective age in terms of future time perspective (i.e., people's perceptions of their remaining opportunities and time) than chronological age; (b) chronological age effects are more domain specific than general in nature; and (c) they are more likely to occur for the instrumental domain as compared to the interpersonal domain. Finally, the results indicated that (d) perceived future time, particularly with respect to remaining opportunities, mediates the relation between chronological age and general gratitude. Overall, the findings suggest that gratitude is subject to a variety of developmental influences across adulthood.     

Aspects pragmatiques de la communication et du langage chez des enfants typiques et des enfants ultérieurement diagnostiqués autistes

The aim of this study is to show that the analysis of pragmatic aspects of communication can allow to locate communicative dysfunctions before the diagnosis of autism is established. The identification of these dysfunctions can be done retrospectively through the analysis of the first gestures and early words. Home movies from children having autism and control ones are collected when they were one, two and three-years old. Data analysis takes into account both forms of communicative gestures and words and functions. Differences between the two groups as a less variety of functions used by children having autism and a fall in their results after the age of two are discussed as possible indicators for an early detection of autism.     

Altered lateralization of dorsal language tracts in 6‐week‐old infants at risk for autism

Altered structural connectivity has been identified as a possible biomarker of autism spectrum disorder (ASD) risk in the developing brain. Core features of ASD include impaired social communication and early language delay. Thus, examining white matter tracts associated with language may lend further insight into early signs of ASD risk and the mechanisms that underlie language impairments associated with the disorder. Evidence of altered structural connectivity has previously been detected in 6‐month‐old infants at high familial risk for developing ASD. However, as language processing begins in utero, differences in structural connectivity between language regions may be present in the early infant brain shortly after birth. Here we investigated key white matter pathways of the dorsal language network in 6‐week‐old infants at high (HR) and low (LR) risk for ASD to identify atypicalities in structural connectivity that may predict altered developmental trajectories prior to overt language delays and the onset of ASD symptomatology. Compared to HR infants, LR infants showed higher fractional anisotropy (FA) in the left superior longitudinal fasciculus (SLF); in contrast, in the right SLF, HR infants showed higher FA than LR infants. Additionally, HR infants showed more rightward lateralization of the SLF. Across both groups, measures of FA and lateralization of these pathways at 6 weeks of age were related to later language development at 18 months of age as well as ASD symptomatology at 36 months of age. These findings indicate that early differences in the structure of language pathways may provide an early predictor of future language development and ASD risk.     

Voice reaction time of stuttering and nonstuttering children and adults

The voice reaction time (VRT) of 5-yr old, 9-yr old, and adult stutterers and nonstutterers was investigated. Subjects initiated the sound / Λ / in response to fifty-five 1000-Hz tones of 1 sec duration. The tones were presented in five equal sets of 11 tones each with the silent intervals between the tones randomly selected to be 3, 4, 5, or 6 sec. Data analysis was based on responses 2–11 for each set. The VRTs for both the stutterers and the nonstutterers decreased significantly as an inverse function of age, with the largest decrease in reaction time occuring between 5 and 9 yr. The VRTs for the stutterers, however, were significantly slower than those of the nonstutterers at each of the three age levels. The results suggest that observed disruption in the laryngeal behavior for at least some stutterers may not result from the development of stuttering with age, but may contribute to early difficulty in the child's ability to produce fluent speech. Consideration of central factors are discussed.     

Transcending bitterness and early paternal loss through mourning and forgiveness

This paper provides an in-depth account of a clinical path to forgiveness following a complicated, delayed mourning of an early loss by a man now entering old age. The search for mourning and forgiveness in light of extreme bitterness in advancing age is highlighted. Despite the intimate connection between mourning and forgiveness, this paper attempts to highlight important differences in their dynamics and psychological aims. Forgiveness is conceived as work, unconsciously motivated, to safeguard and complement the psychological gains of mourning. The distinct features of forgiveness facilitating psychic reorganization, as well as the adaptive function of refusal to forgive as a defense against melancholia, are discussed. The paper concludes that in this case, the motivation for forgiveness was to repair a powerful narcissistic injury.     

The sense of life time in human development

The subjective sense oflife time is the medium within which issues of identity and growth take place. Youth, middle age, early old age, and old age are each presented as developmental stages with dominant experiences oflife time. Directivity, or purposeful movement toward a goal, is then related to the experience of future and occurs in the gap between present and future. The sense of now in old age is viewed as a stage in the life cycle with the potential for unique personal creativity and growth, being free from bondages found at other points in the life cycle.     

Young infants' vocalizations towards mother versus stranger: associations with the infant–mother relationship

Infants' differential vocal response (DVR) towards their mother and a female stranger at 3 months of age has been predominantly investigated as an index of early cognitive functioning. The present study explored the relationship between DVR and different infant and mother indicators of the developing relationship quality in a sample of 23 mother–infant dyads. Mother–infant interactions and stranger–infant interactions were videotaped during home visits when the infants were 3 months old. At the age of 12 months, infants' behaviour was assessed in the Ainsworth's strange situation. In both assessments, mothers noted the infants' behavioural states on 3 successive days. Results revealed a specific relation between DVR and the emotional atmosphere of the early mother–infant interaction. Particularly, DVR was less pronounced in favour of the mother when the mother displayed emotional expressions defined as rejection. DVR is discussed as an index that may indicate both infant emotional engagement and infant cognitive competencies. Copyright © 2005 John Wiley & Sons, Ltd.     

Do the Emotional Benefits of Optimism Vary Across Older Adulthood? A Life Span Perspective

This study examined whether the emotional benefits of dispositional optimism for managing stressful encounters decrease across older adulthood. Such an effect might emerge because age‐related declines in opportunities for overcoming stressors could reduce the effectiveness of optimism. This hypothesis was tested in a 6‐year longitudinal study of 171 community‐dwelling older adults (age range = 64–90 years). Hierarchical linear models showed that dispositional optimism protected relatively young participants from exhibiting elevations in depressive symptoms over time, but that these benefits became increasingly reduced among their older counterparts. Moreover, the findings showed that an age‐related association between optimism and depressive symptoms was observed particularly during periods of enhanced, as compared to reduced, stress. These results suggest that dispositional optimism protects emotional well‐being during the early phases of older adulthood, but that its effects are reduced in advanced old age.     

情绪调节效应的发展:一个V型发展趋势

从青少年早期到成人早期,个体情绪调节等高级社会认知功能得到进一步完善,对情绪调节的需求也日趋增长。情绪调节的发展是青少年情绪社会化发展一个重要的任务,学会采用有效的调节策略对自身情绪进行调节是青少年社会性发展的一个重要表现。在众多关于青少年社会行为研究中,对负性情绪调节能力的探究最为成熟与深入。以往研究指出,儿童青少年对负性情绪的体验激活和调控失败都是导致其非适应性行为的原因,情绪调节方式的错误选择会与其外化行为问题和和内化行为问题有很大的关联。由于青少年适应性行为的习得是多种社会性发展指标的重叠和交叉作用的体现,我们无法完全理清其中的复杂交互作用,因此从情绪调节策略的使用效应发展入手探讨个体的适应是寻求问题解决的一个可行手段。 以往研究者认为,成熟且有效的情绪调节指的是,个体能够通过控制自身的激活和唤醒以达到情绪性、生理性和社交的适应,最后达成个人的目标。情绪调节的发展也可被看作是从被动式的、有他人参与的调节（例如,社会性参照）逐渐进步为主动的、有意识的根据外部线索进行的情绪调节（例如,根据指导语提示调整自己情绪状态）。 本研究旨在探究不同年龄被试（青少年早期、青少年晚期、成人早期）在按照不同指导语提示要求下增强调节和减弱调节调节效应量的年龄差异。选取上海市初中生被试35名（22男,13女;M = 14.06岁,SD = 0.42 岁, 年龄范围：13-15岁）、高中生被试37名（13男,24女;M=16.56岁, SD=0.56岁, 年龄范围：16-18岁）以及成人被试35名（9男,26女;M = 23.60岁,SD = 1.96岁, 年龄范围：20-29岁）,采用3（年龄：初中生、高中生、成人,被试间变量）? 3（情绪刺激：正性、中性、负性,被试内变量）? 3（调节策略：增强调节、减弱调节、不调节,被试内变量）混合实验设计,使用情绪反应性—调节图片任务（Reactivity and Regulation-Image Task,REAR-I Task）对不同年龄被试情绪调节策略使用的效应量进行考察（Carthy, Horesh, Apter, Edge, & Gross, 2010）。 研究发现,从总体趋势来说,情绪调节策略的效应发展呈V型发展趋势。当不同年龄被试按照指导语要求对其情绪体验进行主动调节时,成人被试的调节效应是最大的,初中生次之,而高中生的调节效应则最低。情绪调节的V型发展趋势与以往研究中关于情绪调节态度以及自我发展的趋势相一致。另外,与增强调节策略的使用相比,减弱调节策略效应的发展是最大的。这可能与中国背景下减弱调节的适应价值有关。     

Visual context processing and its development in gamers and non-gamers

Visual context processing was investigated in both action video game players and nonplayers using the Ebbinghaus illusion task (N = 312, 39.4% female) in a cross-sectional study design. When presented in context, players showed markedly poorer target size discrimination accuracy compared with nonplayers in the 6-, 7-, 8-, and 9-years old age groups, but this difference was reduced in 10-years old group and diminished in adults. When presented in isolation (no-context), the two groups displayed similar performance in all age groups. Furthermore, nonplayers (linear) and players (bell curve) showed profoundly different age-related differences in context processing. These findings provide evidence that players might have enhanced perceptual bias to process visual context in the transition from early childhood to early adolescence, and the differences between the two groups start at early ages and continue with distinct developmental profiles.
