Empathy across the adult lifespan: Longitudinal and experience-sampling findings.

This study examined change in self-reported empathy in a four-wave longitudinal study spanning 12 years (1992-2004) and the association between empathy and other measures, including daily reports of relationship experiences. Participants initially ranged in age from 10 years to 87 years. Cross-sectional and longitudinal associations of age with empathy revealed divergent patterns. Whereas cross-sectional analyses suggested that older adults scored lower in empathy than younger adults, longitudinal analyses showed no age-related decline in empathy. This combined pattern suggests that the cross-sectional age-differences reflect a cohort rather than an age effect, with older cohorts reporting lower levels of empathy than younger ones. Independent of age, empathy was associated with a positive well-being (e.g., life satisfaction) and interaction profile (e.g., positive relations with others). In addition, a subsample of participants (n = 114) conducted experience-sampling about social interactions for a week. People with high self-reported empathy perceived their interactions as more meaningful, felt more positive in these interactions, and thought that their interaction partner felt also more positive. Thus, self-reported empathy was meaningfully associated with adults' actual social interactions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Longitudinal hit ratios of classical composers: Reconciling "Darwinian" and expertise acquisition perspectives on lifespan creativity.

What are the prospects for meaningful learning in high-level creativity? An expertise acquisition view of creativity is optimistic about longitudinal improvement; a "Darwinian" view, emphasizing chance, is not. To address this issue, the complete outputs of 65 eminent composers (15,657 works) were tabulated and weighted; each work's masterpiece status was operationalized by citation and recording count measures. Works were assigned to 5-year age intervals, synchronized across composers by age at 1st masterwork. Hit ratio (masterwork-level music divided by total output) was calculated for each interval for each composer. The overall hit ratio trajectory was a single-peaked function, with a maximum around age 50. Reliable age effects held even during composers' mature periods, inconsistent with the chance view and more consistent--although not entirely so--with the expertise acquisition view. Several variables predicted individual differences in hit ratio trajectories; most notably, composers who wrote their best works later in their careers showed stronger agewise increases in hit ratio during their mature periods, even when best works were removed from the trajectories. Implications and prospects for reconciling the expertise and chance views, via a typology of conceptualist versus experimentalist creators, are discussed.

The rise and fall of word retrieval across the lifespan.

Picture-naming performance for 48 black-and-white drawings was investigated in 1,145 Hebrew speakers, ages 5–86. Both a linear and a curvilinear quadratic model fit the data, reflecting an increase in ability with age as well as an increase followed by a decrease beyond that linear rise. Late-life performance was more affected by access difficulty than was early-life performance, with children's responses limited by lexicon size. Immigrants performed more poorly than nonimmigrants, but an identical correlation between participant age and naming scores was found in both groups. We discuss the role of vocabulary funds and controlled access in naming pictures throughout life. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sensory modality, temperament, and the development of sustained attention: A vigilance study in children and adults.

Applying optimal stimulation theory, the present study explored the development of sustained attention as a dynamic process. It examined the interaction of modality and temperament over time in children and adults. Second-grade children and college-aged adults performed auditory and visual vigilance tasks. Using the Carey temperament questionnaires (S. C. McDevitt & W. B. Carey, 1995), the authors classified participants according to temperament composites of reactivity and task orientation. In a preliminary study, tasks were equated across age and modality using d= matching procedures. In the main experiment, 48 children and 48 adults performed these calibrated tasks. The auditory task proved more difficult for both children and adults. Intermodal relations changed with age: Performance across modality was significantly correlated for children but not for adults. Although temperament did not significantly predict performance in adults, it did for children. The temperament effects observed in children-specifically in those with the composite of reactivity-occurred in connection with the auditory task and in a manner consistent with theoretical predictions derived from optimal stimulation theory.

Age differences in five personality domains across the life span.

The present study addresses the issue of age differences in 5 personality domains across the life span in a cross-sectional study. In contrast to most previous studies, the present study follows a methodologically more rigorous approach to warrant that age-related differences in personality structure and mean level can be meaningfully compared. It uses data on 50 items of the Five-Factor Personality Inventory (FFPI) available from a study in a large and representative Dutch sample (N = 2,494; age range: 16 to 91 years) conducted in 1996 for the purpose of establishing norms for the FFPI. After having established strict measurement invariance, tests were made for factor covariances to be equal across age groups, revealing structural continuity of personality. Additionally, factor variances were shown to be equal across age groups. A number of age differences in the mean level of the five personality domains emerged. Specifically, older adults were, on average, more agreeable and, especially, more conscientious than middle-aged and younger adults. Findings from our study suggest that both continuity and change may mark personality over the course of life. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Primary process in children as a function of age.

Extending Freud's formulation with regard to the nature of the primary process, it was posited that language should reflect Freud's content that "contraries are not kept apart from each other, but are treated as though they were identical." Hypothesizing that secondary process thinking is a function of development, 3rd graders and 6th graders were compared on the basis of a paper-and-pencil test wherein the task was to select a synonym word from a group containing the synonym, an antonym, and an irrelevant word. Primary process thinking, as measured above, was found to be more characteristic of the younger group. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Trajectories of autonomy development across the adolescent transition in children with spina bifida.

Objective: The current study investigated individual growth in autonomy development across the adolescent transition, comparing the trajectories of children with and without spina bifida. Method: Individual growth curve modeling procedures were utilized to describe the developmental course of autonomy across four waves of data collection, from ages 9 to 15, and to test whether illness status [spina bifida vs. matched comparison group (N = 68 for both groups at Time 1)] would significantly predict individual variability in autonomy development. Potential moderators [child gender, SES, and Peabody Picture Vocabulary Test (PPVT) score] of the association between illness status and autonomy development were also examined. Results: Children with spina bifida demonstrated distinct developmental trajectories, though the nature of the group differences varied by type of autonomy development (emotional vs. behavioral), context (i.e. school vs. family), and reporter. Significant interactions with PPVT score and child gender were found. Conclusion: Overall, children with spina bifida show considerable developmental resiliency, but may lag behind their peers in specific areas of autonomy. Boys with spina bifida, and children with spina bifida who have lower than average levels of verbal intelligence, appear to be at greater risk for exhibiting delays in autonomy development.

Differences in the functional neuroanatomy of inhibitory control across the adult life span.

Inhibitory control, the ability to suppress irrelevant stimuli, is a fundamental cognitive function that deteriorates during aging, but little is understood about the bases of decline. Thus, we used event-related functional magnetic resonance imaging (fMRI) to study inhibitory control in healthy adults aged 18 to 78. Activation during "successful inhibition" occurred predominantly in right prefrontal and parietal regions and was more extensive, bilaterally, and prefrontally, in the older groups. Presupplementary motor area was also more active in poorer inhibitory performers. Therefore, older adults activate areas that are comparable to those activated by young adults during inhibition, as well as additional regions. The results are consistent with a compensatory interpretation and extend the aging neuroimaging literature into the cognitive domain of inhibition.

Age differences in big five behavior averages and variabilities across the adult life span: Moving beyond retrospective, global summary accounts of personality.

In 3 intensive cross-sectional studies, age differences in behavior averages and variabilities were examined. Three questions were posed: Does variability differ among age groups? Does the sizable variability in young adulthood persist throughout the life span? Do past conclusions about trait development, based on trait questionnaires, hold up when actual behavior is examined? Three groups participated: young adults (18–23 years), middle-aged adults (35–55 years), and older adults (65–81 years). In 2 experience-sampling studies, participants reported their current behavior multiple times per day for 1- or 2-week spans. In a 3rd study, participants interacted in standardized laboratory activities on 8 occasions. First, results revealed a sizable amount of intraindividual variability in behavior for all adult groups, with average within-person standard deviations ranging from about half a point to well over 1 point on 6-point scales. Second, older adults were most variable in Openness, whereas young adults were most variable in Agreeableness and Emotional Stability. Third, most specific patterns of maturation-related age differences in actual behavior were more greatly pronounced and differently patterned than those revealed by the trait questionnaire method. When participants interacted in standardized situations, personality differences between young adults and middle-aged adults were larger, and older adults exhibited a more positive personality profile than they exhibited in their everyday lives.

The control of instrumental action following outcome devaluation in young children aged between 1 and 4 years.

To determine the role of action-outcome learning in the control of young children's instrumental behavior, the authors trained 18- to 48-month-olds to manipulate visual icons on a touch-sensitive display to obtain different types of video clips as outcomes. Subsequently, one of the outcomes was devalued by repeated exposure, and children's propensity to perform the trained actions was tested in extinction. On test, children with a mean age greater than 2.5 years performed the action trained with the devalued outcome less than those trained with the still-valued outcome, thereby demonstrating that their actions were mediated by action-outcome learning. By contrast, the instrumental responses of younger children (mean age     

Infants' Vagal Regulation in the Still-Face Paradigm Is Related to Dyadic Coordination of Mother-Infant Interaction.

The authors investigated relations between mother-infant dyadic coordination and infants' physiological responses. Mothers (N=73) and 3-month-old male and female infants were observed in the still-face paradigm, and mothers' and infants' affective states were coded at 1-s intervals. Synchrony and levels of matching between mother-infant affective states were computed, and infants' heart rate and vagal tone were measured. Infants showed increased negative affect and heart rate and decreased vagal tone during mothers' still-face, indicating physiological regulation of distress. Infants who did not suppress vagal tone during the still-face (nonsuppressors) showed less positive affect, higher reactivity and vagal suppression in normal play and reunion episodes, and lower synchrony in normal play with mothers. The results indicate that infants' physiological regulation in social interaction differs in relation to dyadic coordination of affective behaviors.

The development of memory efficiency and value-directed remembering across the life span: A cross-sectional study of memory and selectivity.

Although attentional control and memory change considerably across the life span, no research has examined how the ability to strategically remember important information (i.e., value-directed remembering) changes from childhood to old age. The present study examined this in different age groups across the life span (N = 320, 5–96 years old). A selectivity task was used in which participants were asked to study and recall items worth different point values in order to maximize their point score. This procedure allowed for measures of memory quantity/capacity (number of words recalled) and memory efficiency/selectivity (the recall of high-value items relative to low-value items). Age-related differences were found for memory capacity, as young adults recalled more words than the other groups. However, in terms of selectivity, younger and older adults were more selective than adolescents and children. The dissociation between these measures across the life span illustrates important age-related differences in terms of memory capacity and the ability to selectively remember high-value information.

Age differences in the big five across the life span: Evidence from two national samples.

Cross-sectional age differences in the Big Five personality traits were investigated using 2 large datasets from Great Britain and Germany: the British Household Panel Study (BHPS; N ≥ 14,039) and the German Socio-Economic Panel Study (GSEOP; N ≥ 20,852). Participants, who ranged in age from 16 to the mid-80s, completed a 15-item version of the Big Five Inventory (e.g., John & Srivastava, 1999) in either 2005 or 2006. The observed age trends were generally consistent across both datasets. Extraversion and Openness were negatively associated with age, whereas Agreeableness was positively associated with age. Average levels of Conscientiousness were highest for participants in middle age. The only exception was Neuroticism, which was slightly negatively associated with age in the BHPS and slightly positively associated with age in the GSEOP. Neither gender nor education level were consistent moderators of age differences in the Big Five. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

False memories in children and adults: Age, distinctiveness, and subjective experience.

This study investigated developmental trends associated with the Deese/Roediger-McDermott false-memory effect, the role of distinctive information in false-memory formation, and participants' subjective experience of true and false memories. Children (5- and 7-year-olds) and adults studied lists of semantically associated words. Half of the participants studied words alone, and half studied words accompanied by pictures. There were significant age differences in recall (5-year-olds evinced more false memories than did adults) but not in recognition of critical lures. Distinctive information reduced false memory for all age groups. Younger children provided with distinctive information, and older children and adults regardless of whether they viewed distinctive information, expressed higher levels of confidence in true than in false memories. Source attributions did not significantly differ between true and false memories. Implications for theories of false memory and memory development are discussed.

Biological correlates of behavioral development in the ant, Novomessor albisetosus (Mayr).

Physical changes are associated with temporal polyethism, the division of labor according to age. The period of developing ovaries corresponds with the age when workers are found with the brood and queen. Resorption of ovaries occurs at a time when workers no longer tend brood and queen. Two bursts of exoskeleton hardening and growth of the poison gland apparatus corresponds with a transitional period in the behavioral development of workers and finally with their development into nest defenders and foragers.

Suggestibility in children as a function of chronological age.

4 measures of visual perceptual suggestibility were obtained on a sample of 290 school children in Grades 1-12. Suggestibility was found to decrease with increasing chronological age. The relationship was significant and curvilinear (p = .001). In order of influence on the children the 4 measures of suggestion could be ranked as follows: prestige suggestion with ambiguous stimuli; conformity suggestion with ambiguous stimuli; prestige suggestion with unambiguous stimuli; baseline or selfsuggestion (p = .001). No sex differences were found. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Shifting development in mid-childhood: The influence of between-task interference.

Performance on the task-switching paradigm is greatly affected by the amount of conflict between tasks. Compared to adults, children appear to be particularly influenced by this conflict, and this suggests that the ability to resolve interference between tasks improves with age. The authors used the task-switching paradigm to investigate how this ability develops in mid-childhood. Experiment 1 compared the ability of 5- to 8-year-olds and of 9- to 11-year-olds to switch between decisions about the color and shape of an object. The 5- to 8-year-olds were slower to switch task and experienced more interference from the irrelevant task than did the 9- to 11-year-olds, which suggests a developmental improvement in resolving conflict between tasks during mid-childhood. In Experiment 2, the influence of stimulus and response interference at different ages was examined by separating the color and shape dimensions of the stimulus and reducing overlap between responses. The results support the development of conflict resolution in task switching during mid-childhood. They also revealed that a complex interplay of factors, including the tasks used and previous experience with the task, affected children’s shifting performance.

Avoiding the potential pitfalls of using negative priming tasks in developmental studies: Assessing inhibitory control in children, adolescents, and adults.

Despite being ignored, visual distractors often produce traceable negative priming (NP) effects that can be used to investigate inhibitory processes. Robust NP effects are typically found with young adults, but not with children. Using 2 different NP tasks, the authors compared NP in 5 different age groups spanning 5 to 25 years of age. The 1st task revealed comparable NP between all age groups, but a linear decrease in NP through childhood to early adulthood. In the 2nd task, NP decreased linearly into adulthood, with children actually showing larger NP than adults. This Age Group ? NP interaction was eliminated, however, when reaction time data were log transformed to control for age differences in overall processing speed. When appropriately transformed data were used, both experiments showed that NP was intact and comparable between children, adolescents, and adults, and suggested that an inhibitory process is fully developed by early childhood. The results highlight how potential pitfalls might be avoided when comparing NP in children and adults. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Interpersonal Mediators in the Intergenerational Transmission of Marital Dysfunction.

Intergenerational transmission of marital functioning was examined in a sample of 60 newlywed couples by collecting (a) retrospective reports of conflict and divorce in spouses' families of origin, (b) data on demographic variables and interactional processes likely to increase risk for adverse marital outcomes, and (c) couples' actual 4-year marital outcomes. The association between wives' parental divorce and marital outcome was mediated by their verbal and physical aggression. The association between negativity in husbands' family of origin and marital outcome was mediated by dyadic expressions of negative affect. Demographic variables did not operate as mediators. Negative interpersonal processes appear to be a vehicle by which experiences in the family of origin are carried forward into the next generation of relationships.

Measurement of smoking outcome expectancies in children: The Smoking Consequences Questionnaire-Child.

A measure of smoking outcome expectancies was developed for children ages 7-12 years. Confirmatory factor analysis (CFA) was used to determine whether a 1-, 2-, 3-, or 4-factor solution was most appropriate for the data set. CFA revealed that the 3-factor model produced the most adequate fit (Positive Reinforcement, Negative Consequences, and Weight Control). The resulting 15-item measure was named the Smoking Consequences Questionnaire-Child (SCQ-C). The fit of the 3-dimensional structure was then examined separately for 3 age groups representing young (7- to 8-year-old), middle (9- to 10-year-old), and old (11- to 13-year-old) children. Overall, the 3-factor structure fit the data well for the 3 groups. As such, we examined the relations of the 3 scales with antecedent variables for the entire sample. The Positive Reinforcement scale was associated with children's smoking behavior and having a family member or peers who smoked. The Negative Consequences scale was inversely related to having a family member or peer who smoked. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
