Executive Function (EF) and Effortful Control (EC) have traditionally been viewed as distinct constructs related to cognition and temperament during development. More recently, EF and EC have been implicated in top‐down self‐regulation ‐ the goal‐directed control of cognition, emotion, and behavior. We propose that executive attention, a limited‐capacity attentional resource subserving goal‐directed cognition and behavior, is the common cognitive mechanism underlying the self‐regulatory capacities captured by EF and EC. We addressed three related questions: (a) Do behavioral ratings of EF and EC represent the same self‐regulation construct? (b) Is this self‐regulation construct explained by a common executive attention factor as measured by performance on cognitive tasks? and (c) Does the executive attention factor explain additional variance in attention deficit hyperactivity disorder (ADHD) problems to behavioral ratings of self‐regulation? Measures of performance on complex span, general intelligence, and response inhibition tasks were obtained from 136 preadolescent children (M = 11 years, 10 months, SD = 8 months), along with self‐ and parent‐reported EC, and parent‐reported EF, and ADHD problems. Results from structural equation modeling demonstrated that behavioral ratings of EF and EC measured the same self‐regulation construct. Cognitive tasks measured a common executive attention factor that significantly explained 30% of the variance in behavioral ratings of self‐regulation. Executive attention failed to significantly explain additional variance in ADHD problems beyond that explained by behavioral ratings of self‐regulation. These findings raise questions about the utility of task‐based cognitive measures in research and clinical assessment of self‐regulation and psychopathology in developmental samples. 相似文献

A laboratory experiment investigated the effects of numerical group size and logical group size (i.e., group heterogeneity in regard to task demands) on the performance of groups addressing an idea generation task while using computer-mediated communication. Six different numerical group sizes were studied, which ranged from 5 to 10 members. Logical size was manipulated by varying the amount of task-relevant information given to a particular group member. Larger logical group sizes (heterogeneous groups) were induced by distributing unique task-relevant information among group members; smaller logical group sizes (homogeneous groups) were induced by providing all task information to all members. A significant main effect for numerical group size showed that larger groups outperformed smaller groups. Numerical group size interacted with logical group size resulting in greater performance gains for increased numerical group size within heterogeneous groups. Average contributions per group member diminished with increased numerical group size for homogeneous groups and increased for heterogeneous groups. 相似文献

Forty male undergraduates ingested either a high dose of alcohol or a placebo, and were either provided with a nonaggressive norm or not, prior to being provoked by an opponent during a competitive reaction time task. Aggression was assessed by the intensity of shocks administered by the subject to the bogus opponent. Results suggest that the provision of an explicit nonaggressive norm enabled highly intoxicated subjects to moderate their aggressive responding even in a highly competitive situation. These findings are discussed in terms of current cognitive disruption models of alcohol-related aggression which assume intoxicated persons are unable to process information concerning appropriate standards of conduct. 相似文献

Interteaching is a new method of classroom instruction that is based on behavioral principles but offers more flexibility than other behaviorally based methods. We examined the effectiveness of interteaching relative to a traditional form of classroom instruction-the lecture. In Study 1, participants in a graduate course in special education took short quizzes after alternating conditions of interteaching and lecture. Quiz scores following interteaching were higher than quiz scores following lecture, although both methods improved performance relative to pretest measures. In Study 2, we also alternated interteaching and lecture but counterbalanced the conditions across two sections of an undergraduate research methods class. After each unit of information, participants from both sections took the same test. Again, test scores following interteaching were higher than test scores following lecture. In addition, students correctly answered more interteaching-based questions than lecture-based questions on a cumulative final test. In both studies, the majority of students reported a preference for interteaching relative to traditional lecture. In sum, the results suggest that interteaching may be an effective alternative to traditional lecture-based methods of instruction. 相似文献

During real-world scene viewing, humans must prioritize scene regions for attention. What are the roles of low-level image salience and high-level semantic meaning in attentional prioritization? A previous study suggested that when salience and meaning are directly contrasted in scene memorization and preference tasks, attentional priority is assigned by meaning (Henderson & Hayes in Nature Human Behavior, 1, 743–747, 2017). Here we examined the role of meaning in attentional guidance using two tasks in which meaning was irrelevant and salience was relevant: a brightness rating task and a brightness search task. Meaning was represented by meaning maps that captured the spatial distribution of semantic features. Meaning was contrasted with image salience, represented by saliency maps. Critically, both maps were represented similarly, allowing us to directly compare how meaning and salience influenced the spatial distribution of attention, as measured by fixation density maps. Our findings suggest that even in tasks for which meaning is irrelevant and salience is relevant, meaningful scene regions are prioritized for attention over salient scene regions. These results support theories in which scene semantics play a dominant role in attentional guidance in scenes. 相似文献

Mental fatigue influence on effort-related cardiovascular response: difficulty effects and extension across cognitive performance domains 总被引:2,自引:0,他引:2

Two experiments investigated cardiovascular effects of mental fatigue as a function of (1) the difficulty of the cognitive
challenge with which participants were confronted, and (2) the relevance of that challenge to the activity that instigated
the fatigue. In the first, participants performed an easy (fatigue low) or difficult (fatigue high) counting task and then
were presented an arithmetic challenge (task B relevance high) or a scanning challenge (task B relevance low) with instructions
that they would avoid a noise if they attained a modest performance standard. Analysis of blood pressure responses assessed
during the work periods revealed fatigue main effects, reflecting stronger responses for High Fatigue participants, regardless
of the character of the second task. In the second, the procedure was the same except that it included a high performance
standard and provided the chance to win a prize. Analysis of the pressure data revealed fatigue x work period interactions,
reflecting relatively stronger responses among High Fatigue participants in work period 1, but relatively weaker responses
among these participants in work period 2. Results confirm previous findings and support an analysis of fatigue influence
on effort and associated cardiovascular responses. They also argue against the idea that mental fatigue influence may be confined
to relevant cognitive performance realms.

This essay addresses the issue of indigeneity in terms of local cultures. The authors do so in conversation with Kim, Yang,
and Hwang’s recent book, Indigenous and Cultural Psychology: Understanding People in Context. The life and work of Virgilio Enriquez is reviewed briefly as an exemplary indigenous psychologist. He illustrates the possibility
of an indigenous psychology with a local, regulative grammar of cognition, affect, behavior, and relationships. The accounts
of the tower of Babel and Constantine point to the irreversible damage of homogenizing culture and imposing it on other cultures.
We argue that the imposition of a local, particular Western psychology on a global scale might risk a similar cost. The authors
propose that current research in indigenous psychologies might take more seriously the notion that culture is not monolithic
but should be understood from the point of view of the analysis of power relationships. Secondly, the authors argue that the
role of language has not received sufficient attention in terms of shaping thought and increasing the incommensurability between
cultures. Thirdly, it is argued that positivist epistemology has dominated the field and that more hermeneutic approaches
must be considered. Fourth, the question must be asked regarding who controls indigenous research. Too often control has been
exogenous rather than in the hands of local leaders. Finally, it is suggested that North Americans would do well to examine
and recognize the indigeneity of their own psychology. 相似文献

This study used a multidimensional assessment of interpersonal power to examine associations between indices of relationship
power and relationship functioning in 92 adolescent romantic couples recruited from rural communities in the Rocky Mountain
region of the USA. Significant differences emerged between girlfriends and boyfriends in their reports of decision making
authority, perceptions of humiliating behaviors by the partner, and ratings of themselves giving-in to their partners in a
videotaped interaction task. In addition, indices of interpersonal power were associated with dating aggression and relationship
satisfaction for both girlfriends and boyfriends, although gender differences emerged in the patterns of association between
power and outcomes. Results are discussed in light of current developmental, feminist, and social psychological theories of
interpersonal power in romantic relationships. 相似文献
