Gamma- and theta-band synchronization during semantic priming reflect local and long-range lexical–semantic networks

Anterior and posterior brain areas are involved in the storage and retrieval of semantic representations, but it is not known how these areas dynamically interact during semantic processing. We hypothesized that long-range theta-band coherence would reflect coupling of these areas and examined the oscillatory dynamics of lexical–semantic processing using a semantic priming paradigm with a delayed letter-search task while recording subjects’ EEG. Time–frequency analysis revealed facilitation of semantic processing for Related compared to Unrelated conditions, which resulted in a reduced N400 and reduced gamma power from 150 to 450 ms. Moreover, we observed greater anterior–posterior theta coherence for Unrelated compared to Related conditions over the time windows 150–425 ms and 600–900 ms. We suggest that while gamma power reflects activation of local functional networks supporting semantic representations, theta coherence indicates dynamic coupling of anterior and posterior areas for retrieval and post-retrieval processing and possibly an interaction between semantic relatedness and working memory.     

Focus on opportunities as a mediator of the relationships between age, job complexity, and work performance

Focus on opportunities is a cognitive-motivational facet of occupational future time perspective that describes how many new goals, options, and possibilities individuals expect to have in their personal work-related futures. This study examined focus on opportunities as a mediator of the relationships between age and work performance and between job complexity and work performance. In addition, it was expected that job complexity buffers the negative relationship between age and focus on opportunities and weakens the negative indirect effect of age on work performance. Results of mediation, moderation, and moderated mediation analyses with data collected from 168 employees in 41 organizations (mean age = 40.22 years, SD = 10.43, range = 19–64 years) as well as 168 peers providing work performance ratings supported the assumptions. The findings suggest that future studies on the role of age for work design and performance should take employees’ focus on opportunities into account.     

Are Older Adults Wiser Than College Students? A Comparison of Two Age Cohorts

This study examined whether (a) older adults are wiser than college students, (b) college-educated older adults are wiser than current college students, and (c) wise older adults show evidence of personal growth. Using a sample of 477 undergraduate college students and 178 older adults (age 52+), results showed that college students tended to score as high on the self-administered three-dimensional wisdom scale (3D-WS) as older adults. However, college-educated older adults tended to score significantly higher on the reflective and affective dimensions of wisdom and the overall score of the 3D-WS and than did current college students. Qualitative evidence suggests that many older adults, particularly in the top 20% of wisdom scorers, grew wiser with age by learning from life experiences. The results indicate that wisdom might increase with age for individuals with the opportunity and motivation to pursue its development.     

Ethics Consultation in Pediatrics: Long-Term Experience From a Pediatric Oncology Center

There is little information about the content of ethics consultations (EC) in pediatrics. We sought to describe the reasons for consultation and ethical principles addressed during EC in pediatrics through retrospective review and directed content analysis of EC records (2000–2011) at St. Jude Children's Research Hospital. Patient-based EC were highly complex and often involved evaluation of parental decision making, particularly consideration of the risks and benefits of a proposed medical intervention, and the physician's fiduciary responsibility to the patient. Nonpatient consultations provided guidance in the development of institutional policies that would broadly affect patients and families. This is one of the few existing reviews of the content of pediatric EC and indicates that the distribution of ethical issues and reasons for moral distress are different than with adults. Pediatric EC often facilitates complex decision making among multiple stakeholders, and further prospective research is needed on the role of ethics consultation in pediatrics.     

Age differences in managing response to sadness elicitors using attentional deployment,positive reappraisal and suppression

The current study investigated age differences in the use of attentional deployment, positive reappraisal and suppression while regulating responses to sadness-eliciting content. We also tested to what extent these emotion regulation strategies were useful for each age group in managing response to age-relevant sad information. Forty-two young participants (M_age = 18.5, SE = .15) and 48 older participants (M_age = 71.42, SE = 1.15) watched four sadness-eliciting videos (about death/illness, four to five minutes long) under four conditions—no-regulation (no regulation instructions), attentional deployment (divert attention away), positive reappraisal (focus on positive outcomes) and suppression (conceal emotional expressions). We assessed negative emotional experience, expression, skin conductance level (SCL) and visual fixation duration while participants watched the emotional clips and followed the instructions for each condition. Results suggest that older adults were more successful than younger adults at implementing both attentional deployment and positive reappraisal. Ability to suppress emotions appears to remain stable with age. Within age-group comparisons suggested that for the older adults, positive reappraisal was a more useful emotion regulation strategy than the others, while the pattern among younger adults was less conclusive. Age-relevant differences in motivation and successful emotion regulatory efforts based on theoretical and empirical literatures are discussed.     

‘Undesirable’ and ‘desirable’ shifts in children's responses to repeated questions: age differences in the effect of providing a rationale for repetition

This study examined factors influencing children's tendency to shift responses when questions are repeated within an interview. Forty nine 4–5‐year‐olds and 40 7–8‐year‐olds were questioned about a video they had seen, with questions repeated by the same or a different interviewer. Half the children were given a rationale for question repetition, and half were not. Overall, the older children shifted less than the younger children, and, unlike the younger children, more to misleading than unbiased questions. The rationale did not affect overall shifting, but reduced the probability of ‘undesirable’ shifts (towards inaccuracy) in the younger children, and increased ‘desirable’ shifts (towards accuracy) at both ages. In the younger children, the rationale reduced total number of shifts, but only with the same interviewer, while in the older children the reverse applied. The results suggest developmental progression in the relative contributions of memorial and social/motivational factors to shifting. Implications for investigative interviewing with children are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Why Do You Regulate What You Eat? Relationships Between Forms of Regulation, Eating Behaviors, Sustained Dietary Behavior Change, and Psychological Adjustment

In 3 studies, the authors examined how autonomous and controlled forms of motivation for the regulation of eating behaviors were related to self-reported eating behaviors, and sustained dietary behavior change. Studies 1 and 2 supported the factorial structure and the psychometric properties of a scale designed to measure different forms of regulation as defined by Self-Determination Theory. A motivational model of the regulation of eating behaviors suggested that an autonomous regulation was positively associated with healthy eating behaviors whereas a controlled regulation was positively associated with dysfunctional eating behaviors and negatively associated with healthy eating behaviors. In Study 3, long-term adherence to healthier dietary behaviors in a population at risk for coronary artery disease was examined over a 26-week period. A general measure of self-determined motivation assessed at week 1 was found to be a reliable predictor of the level of self-determination for eating behaviors 13 weeks later. In turn, self-determination for eating behaviors was a significant predictor of dietary behavior changes at 26 weeks. Finally, the dietary behavior measures were related to improvements in weight and blood lipid parameters (LDL-cholesterol, HDL-cholesterol, triglycerides). Results are discussed in terms of their implication for the integration and maintenance of a successful healthy regulation.
