ABSTRACT

Humans routinely perform visual search towards targets to adapt to the environment. These sequences of ballistic eye movements are shaped by a combination of top–down and bottom–up factors. Recent research documented that human observers display cultural-specific fixation patterns in a range of visual processing tasks. In particular, eye movement strategies extracting information from faces clearly differs between Western Caucasian (WC) and East Asian (EA) observers. However, whether such cultural differences are also present for visual scene processing remains debated. To this aim, we recorded the eye movements of WC and EA observers while they were solving visual search problems parametrically varying in difficulty: Where’s Waldo. Both groups had a comparable familiarity with the Waldo books reaching a comparable level of accuracy in target detection. Both cultural groups also showed a comparable temporal effect on inhibition of return, with longer fixation durations when saccades were performed to a return location compared to other locations. Westerners, however, located Waldo faster than Easterners. Interestingly, this modulation of speed was likely related to differences occurring on the low-level mechanisms of spatial inhibition of return, with EA observers returning more often to previously visited locations than the WC observers. This suboptimal eye movement strategy in the Easterners might be engendered by their cultural perceptual bias consisting in? a greater use of extra-foveal information. Overall, our data point towards the existence of a subtle, but significant difference in the processing of visual scenes across observers from different cultures during active visual search.  相似文献

The Monty Hall dilemma (MHD) is a notorious probability problem with a counterintuitive solution. There is a strong tendency to stay with the initial choice, despite the fact that switching doubles the probability of winning. The current randomised experiment investigates whether feedback in a series of trials improves behavioural performance on the MHD and increases the level of understanding of the problem. Feedback was either conditional or non-conditional, and was given either in frequency format or in percentage format. Results show that people learn to switch most when receiving conditional feedback in frequency format. However, problem understanding does not improve as a consequence of receiving feedback. Our study confirms the dissociation between behavioural performance on the MHD, on one hand, and actual understanding of the MHD, on the other. We discuss how this dissociation can be understood.  相似文献

The current study claims that measures of sexual recidivism provide a distorted view of the criminal activity of adult sex offenders. To address this important limitation, the criminal career perspective is presented and key concepts are defined and described. The study also provides an up-to-date review of the scientific literature on various criminal career parameters of the sexual criminal activity of adult sex offenders. Hence, current empirical knowledge on the prevalence, age of onset, frequency, continuity, versatility, and desistance from sex offending is presented. The findings highlight the complexities of the sexual criminal career of adult sex offenders, and most importantly, its dynamic aspect, both of which are not captured by traditional measures of sexual recidivism. The review also underscores the importance of recognizing that sexual offending develops according to a series of stages, that, if not recognized, may lead to the underestimation of risk for some and over-estimation of risk for others. The review provides a framework to stimulate new areas of research as well as policy-development that is not limited to the identification of the “high-risk” convicted sex offenders.  相似文献

The practice of making disability worlds is investigated both theoretically, in the context of developments in disability studies, in particular in the cultural model of disability, and practically in two examples, namely inclusive education environments and public environments. Theoretically, we argue that disability worlds can be better understood by introducing the notion of disability cosmology as the largest possible perspective on the making of disability worlds. A cultural model research perspective of disability consists then of the complementary study of disability identity, culture and cosmology. The practical examples work out the particularities of making and understanding disability worlds. In the making of disability worlds, much attention goes to the ways in which disability worlds relate to the normative world; for example in the formation of boundaries and transgressions, but also fundamentally how disability adds to becoming human.  相似文献

Picture naming speed is strongly influenced by the age of acquisition (AoA) of words. Most studies of AoA have relied on adults' AoA ratings. However, objective AoA has been found to be a stronger determinant of picture naming latencies. Whereas objective AoA norms for words have been collected for some language communities, no objective AoA measures for words were previously available in French. The study provides objective AoA norms for a set of 230 object names following the procedures used by Morrison, Chappell, and Ellis (1997) to collect objective AoA measures in English. The relationships between objective AoA measures, rated AoA, other variables used in psycholinguistic experiments (name agreement, image agreement, conceptual familiarity, etc.), the English data collected by Morrison et al., and naming latencies are analysed and discussed. In addition, reanalyses of data on picture naming latencies (Bonin, Chalard, Méot, & Fayol, 2002) with the use of objective AoA norms are provided. Stepwise multiple analyses show that objective AoA is a stronger determinant of (spoken and written) naming latencies than rated AoA, whereas objective word frequency is not a reliable independent determinant and does not interact reliably with AoA in any of the analyses.  相似文献

This study evaluated the extent to which a conjugate reinforcement schedule (CONJ) involving a contingency between pedaling a stationary bike and viewing a preferred movie could serve as a translational preparation for the analysis of automatically reinforced behavior. In part, researchers examined whether providing participants with either an accurate or an inaccurate rule about the extinction (EXT) component of a multiple schedule (MULT) contributed to the development of control by the MULT (CONJ EXT) schedule. Results show schedule control emerged for four of five participants who received the accurate rule and none of the five participants who received the inaccurate rule. In addition, participants who received accurate rules typically increased pedaling during CONJ components that followed two consecutive EXT components, suggesting that they experienced deprivation for audio and visual stimulation generated by pedaling. These preliminary findings suggest that researchers could use this translational preparation to identify matched interventions for some automatically reinforced behavior.  相似文献

Goals are central to current treatments of work motivation, and goal commitment is a critical construct in understanding the relationship between goals and performance. Inconsistency in the measurement of goal commitment hindered early research in this area but the nine-item, self-report scale developed by Hollenbeck, Williams, and Klein (1989b), and derivatives of that scale, have become the most commonly used measures of goal commitment. Despite this convergence, a few authors, based on small sample studies, have raised questions about the dimensionality of this measure. To address the conflicting recommendations in the literature regarding what items to use in assessing goal commitment, the current study combines the results of 17 independent samples and 2918 subjects to provide a more conclusive assessment by combining meta-analytic and multisample confirmatory factor analytic techniques. This effort reflects the first combined use of these techniques to test a measurement model and allowed for the creation of a database substantially larger than that of previously factor analyzed samples containing these scale items. By mitigating sampling error, the results clarified a number of debated issues that have arisen out of previous small sample factor analyses and revealed a five-item scale that is unidimensional and equivalent across measurement timing, goal origin, and task complexity. It is recommended that this five-item scale be used in future research assessing goal commitment. Copyright 2001 Academic Press.  相似文献

In a sample of 365 college students, the authors examined the incremental role of personality, self-efficacy, and interests in explaining level of educational aspirations. Measures were the Adjective Check List (ACL) (Gough & Heilbrun, 1983), the Skills Confidence Inventory (Betz, Borgen, & Harmon, 1996), and the six General Occupational Themes (GOTs) of the Strong Interest Inventory (Harmon, Hansen, Borgen, & Hammer, 1994). The Big Five personality dimensions were estimated from the ACL using John's (1990) method. The authors predicted that each of these domains would make independent contributions to explaining level of educational aspirations (1= bachelor's, 2= master's, and 3= doctorate). Sequentially, following Lent, Brown, and Hackett's (1994) social cognitive career theory, blocks of the Big Five, six General Conference Themes, and six GOTs were entered into a hierarchical regression predicting educational level. With the addition of each block, R2 rose from .10, to .26, to .29 for the total sample; similar incremental predictions were obtained separately for women (.13, .29, and .32) and men (.13, .30, and .37).  相似文献

This article presents data from an ABAB single case design study of a 60-year-old Caucasian male diagnosed with chronic major depressive disorder. The Cognitive Behavioral Analysis System of Psychotherapy (CBASP) was utilized throughout treatment, and both BDI scores and diagnostic interviews revealed states of partial, and ultimately full remission during the course of treatment. A focus was ultimately placed on generalizing what the patient learned in-session to his outside life. Additionally, the unique design of this case illustrated that the patient experienced a moderate reduction in depressive symptoms, prior to the long-term alteration of his coping style. A stable change in his coping style was necessary before full and sustained recovery was evidenced.  相似文献
