According to Relational Frame Theory (RFT) Crel denotes a contextual stimulus that controls a particular type of relational response (sameness, opposition, comparative, temporal, hierarchical etc.) in a given situation. Previous studies suggest that contextual functions may be indirectly acquired via transfer of function. The present study investigated the transfer of Crel contextual control through equivalence relations. Experiment 1 evaluated the transfer of Crel contextual functions for relational responses based on sameness and opposition. Experiment 2 extended these findings by evaluating transfer of function using comparative Crel stimuli. Both experiments followed a similar sequence of phases. First, abstract forms were established as Crel stimuli via multiple exemplar training (Phase 1). The contextual cues were then applied to establish arbitrary relations among nonsense words and to test derived relations (Phase 2). After that, equivalence relations involving the original Crel stimuli and other abstract forms were trained and tested (Phase 3). Transfer of function was evaluated by replacing the directly established Crel stimuli with their equivalent stimuli in the former experimental tasks (Phases 1 and 2). Results from both experiments suggest that Crel contextual control may be extended via equivalence relations, allowing other arbitrarily related stimuli to indirectly acquire Crel functions and regulate behavior by evoking appropriate relational responses in the presence of both previously known and novel stimuli. 相似文献

Decision theory and game theory rest on a fundamental assumption that players seek to maximize their individual utilities, but in some interactive decisions it seems intuitively reasonable to aim to maximize the utility of the group of players as a whole. Such team reasoning requires collective preferences and a distinctive mode of reasoning from preferences to decisions. Findings from two experiments provide evidence for collective preferences and team reasoning. In lifelike vignettes (Experiment 1) and abstract games (Experiment 2) with certain structural properties, most players preferred team-reasoning strategies to strategies supporting unique Nash equilibria, although individually rational players should choose equilibrium strategies. These findings suggest that team reasoning predicts strategy choices more powerfully than orthodox game theory in some games. 相似文献

Age of acquisition (AoA) is an important psycholinguistic variable that affects the speed and accuracy of lexical processing
in tasks such as word naming, picture naming, and lexical decision. In the present work, we collected AoA ratings for 1,749
Portuguese words (nouns, verbs, adjectives, and adverbs), using a 9-point scale that was first proposed by Carroll and White
(1973). We analyzed the relation between AoA ratings and other psycholinguistic variables (length measures, neighborhood density,
written-word frequency, familiarity, imageability, and concreteness), and we assessed reliability by correlating our ratings
with those from other databases presented for Portuguese, English, Spanish, and Italian. The full database can be downloaded

Ethics has emerged as one of the most critical issues facing organizations. Given its importance, an extensive literature has evolved to understand the causes and consequences of (un)ethical decision making and behaviors in organizations. To date, much of this research has relied on research methods (e.g., experiments) that emphasize internal validity and control over external validity and generalizability. Although very informative, such studies frequently utilize samples that are not representative of working adults and their designs often fail to capture the contextual complexity that defines the day-to-day realities of organizational life. In this light, this special issue of Personnel Psychology encouraged scholars to investigate ethics within organizations and to offer rich theoretical explanations for why ethical failures and successes occur. The articles in this special issue address this important research agenda and make significant contributions to our understanding of ethics in organizations. Our introduction synthesizes these works, provides an overview of issues facing the broader behavioral ethics literature, and discusses areas for future research. 相似文献

Variants of adaptive Bayesian procedures for estimating the 5% point on a psychometric function were studied by simulation. Bias and standard error were the criteria to evaluate performance. The results indicated a superiority of (a) uniform priors, (b) model likelihood functions that are odd symmetric about threshold and that have parameter values larger than their counterparts in the psychometric function, (c) stimulus placement at the prior mean, and (d) estimates defined as the posterior mean. Unbiasedness arises in only 10 trials, and 20 trials ensure constant standard errors. The standard error of the estimates equals 0.617 times the inverse of the square root of the number of trials. Other variants yielded bias and larger standard errors. 相似文献

This paper reports a case study of acquired surface alexia in Spanish and discusses the most suitable tests to detect this syndrome in a writing system that is very regular for reading at the segmental and supra-segmental levels. Patient MM has surface alexia characterized by quantitatively good performance in reading words and pseudowords; accurate but slow and syllabic reading of words, nonwords and sentences; good performance in lexical decision tasks including words and nonwords; errors in lexical decision with pseudohomophones; and homophone confusions. This pattern of reading can be interpreted as a disorder in the lexical reading route and overdependence on the non-lexical route. We discuss nonlexical impairments and the interpretation of alexia and suggest tasks to identify surface alexia in a shallow orthography. 相似文献
