ABSTRACT Normal aging has been associated with executive control deficits, but it is as yet unclear whether different executive subprocesses are differentially affected during the course of aging. The present study aimed to investigate age effects on a range of executive control subcomponents. Four consecutive age groups (20–30 years, 31–45 years, 46–60 years, 61–75 years), matched on present state IQ and mood, were compared on tasks of strategic memory processing, verbal fluency, reasoning, inhibition, task management, and self-rating of executive abilities. Deficits concerning the suppression of habitual and experimentally induced prepotent response tendencies and the ability to efficiently divide attention were observed in subjects over 60 years of age compared to the younger groups, while memory, verbal fluency, and reasoning were largely unaffected. Results suggest a sharp decline of executive function after age 60 and a differential course of different executive subcomponents across aging, adding further support to a multi-dimensional model of executive function. 相似文献

Demonstrations of nonhuman ability to share resources and reciprocate such sharing seem contingent upon the experimental paradigm used (note Horner et al. in PNAS 108:13847–13851, 2011). Here, such behaviour in Grey parrots (Psittacus erithacus) was tested in two experiments, both designed to avoid possible issues involving apparatus complexity, visible reward options, and physical competition and/or limited communication between subjects. In both studies, two birds, working in dyads, took turns in choosing one of four different coloured cups with differing outcomes: empty (null, nonrewarding), selfish (keeping reward for oneself), share (sharing a divisible reward), or giving (donating reward to other). In Experiment 1, each bird alternated choices with a conspecific; in Experiment 2, each bird alternated with the three humans with different specific intentions (selfish, giving, or copying bird’s behaviour). In both experiments, birds could learn to cooperatively reward a partner at little cost to themselves—by sharing—and potentially maximize overall reward by reciprocating such sharing. Experiment 1 results differed depending upon which bird began a session: Only our dominant bird, as follower, was willing to share. In Experiment 2, birds’ responses tended towards consistency with human behaviour. Our dominant bird was willing to share a reward with a human who was willing to give up her reward, was selfish with the selfish human, and tended towards sharing with the copycat human; our subordinate bird tended slightly towards increased sharing with the generous human and selfishness with the selfish human, but did not change behaviour with the copycat. 相似文献

A hallmark of the human language faculty is the use of syntactic rules. The natural vocalizations of animals are syntactically simple, but several studies indicate that animals can detect and discriminate more complex structures in acoustic stimuli. However, how they discriminate such structures is often not clear. Using an artificial grammar learning paradigm, zebra finches were tested in a Go/No-go experiment for their ability to distinguish structurally different three-element sound sequences. In Experiment 1, zebra finches learned to discriminate ABA and BAB from ABB, AAB, BBA, and ABB sequences. Tests with probe sounds consisting of four elements suggested that the discrimination was based on attending to the presence or absence of repeated A- and B-elements. One bird generalized the discrimination to a new element type. In Experiment 2, we continued the training by adding four-element songs following a ‘first and last identical versus different’ rule that could not be solved by attending to repetitions. Only two out of five birds learned the overall discrimination. Testing with novel probes demonstrated that discrimination was not based on using the ‘first and last identical’ rule, but on attending to the presence or absence of the individual training stimuli. The two birds differed in the strategies used. Our results thus demonstrate only a limited degree of abstract rule learning but highlight the need for extensive and critical probe testing to examine the rules that animals (and humans) use to solve artificial grammar learning tasks. They also underline that rule learning strategies may differ between individuals. 相似文献

A widened attentional focus, that is typically associated with ADHD, has been postulated to be accompanied by enhanced creative ability. However, creativity has been only limitedly examined in ADHD. Performance across several creativity measures were investigated in three groups: adolescents with ADHD, those with conduct disorder, and a healthy control sample. The ADHD group exhibited selective cognitive advantages and disadvantages by demonstrating an enhanced ability in overcoming the constraining influence of examples, but a reduced capacity to generate a functional invention during an imagery task. These findings are interpreted with reference to inhibitory control mechanisms and the contextual modulation of creative cognition. 相似文献

Eating disorders (EDs) have become one of the biggest mental-health problems in the last decades, especially among youth and women. The present study aims to analyse the suitability of Prochaska and DiClemente’s Transtheoretical Model of Change when applied to the living experiences of people diagnosed with ED and their carers. For this purpose, we applied a narrative biographic approach to the ways in which people face their problems and vital development in the ED domain. Through the narrative analysis of these autobiographies, we aimed to study the patients’ own notions of ‘change’, ‘problem’ and ‘vital trajectory’. We focused on five autobiographic interviews of persons diagnosed as ED (four women and a man). The analysis yields three discourses which organize and give sense to our participants’ vital transitions: a discourse of functional adaptation to events and experiences; one that pays attention to random events and people entering your life; and one that has the personal initiative and agency of an individual agent at its core. It also illuminates particular ways of understanding determination, contemplation and pre-contemplation. These ways of understanding change are shown to extend the possible ways of thinking about people’s lives and ED patients’ perspectives. 相似文献

In this cross‐cultural meta‐analysis, we examine the relationships between person–environment [P–E] fit and work attitudes (organizational commitment, job satisfaction, and intent to quit) as well as job performance based on 96 studies (110 independent samples) conducted in East Asia, Europe, and North America. We compare the results across cultures while focusing on 4 dimensions of P–E fit (person‐job fit, person–organization fit, person–group fit, and person–supervisor fit) separately and jointly. Findings suggest that the effects of rational fit (person–organization and person–job fit) are (relatively) stronger in North America and, to a lesser extent, Europe than in East Asia. However, the effects of relational fit (person–group and person–supervisor fit) are (relatively) stronger in East Asia than in North America. This highlights that in collectivistic and high power distance (vs. individualistic and low power distance) cultures, relational (vs. rational) fit is more salient in influencing employees’ perceptions about their work environments. Results are less clear concerning job performance. What is common across cultures is that, regardless of which dimension of P–E fit is being considered, fit happens and high levels of fit lead to positive outcomes, confirming the universal relevance of fit phenomenon. 相似文献

The purpose of the study was to investigate a possible association between brain activation in functional magnetic resonance imaging scans, cognition and school performance in extremely preterm children and term born controls. Twenty eight preterm and 28 term born children were scanned while performing a working memory/selective attention task, and school results from national standardized tests were collected. Brain activation maps reflected difference in cognitive skills but not in school performance. Differences in brain activation were found between children born preterm and at term, and between high and low performers in cognitive tests. However, the differences were located in different brain areas. The implication may be that lack of cognitive skills does not alone explain low performance due to prematurity. 相似文献

We examined the impact of induced goal orientation on individuals' positive‐ and negative‐activating mood when taking part in high‐ or low‐challenging assignments. Results indicated that performing a low‐challenging assignment leads to a higher positive‐activating mood with a performance‐approach orientation than with a mastery approach, or no goal orientation. In contrast, conducting a high‐challenging assignment leads to a higher positive‐activating mood with a mastery approach than with a performance approach, or no goal orientation. These findings suggest that high‐challenging assignments are best instructed with a focus on learning whereas low‐challenging assignments are best instructed with a focus on superior performance. 相似文献
