Strayer and colleagues (Grison & Strayer, 2001; Malley & Strayer, 1995; Strayer & Grison, 1999) have reported experiments in which negative priming by ignored stimuli occurred only for stimuli that were repeatedly sampled from small sets. These results were argued to be inconsistent with episodic/mismatch accounts of negative priming. We show here that a dependence of negative priming on multiple repetition is wholly consistent with such theories. Furthermore, we argue that the inhibitory theory proposed by Strayer and colleagues cannot account for major findings regarding negative priming and that anomalies in the data reported by Grison and Strayer are more parsimoniously explained by episodic/mismatch accounts. 相似文献

In standard visual search experiments, observers search for a target item among distracting items. The locations of target items are generally random within the display and ignored as a factor in data analysis. Previous work has shown that targets presented near fixation are, in fact, found more efficiently than are targets presented at more peripheral locations. This paper proposes that the primary cause of this “eccentricity effect” (Carrasco, Evert, Chang, & Katz, 1995) is an attentional bias that allocates attention preferentially to central items. The first four experiments dealt with the possibility that visual, and not attentional, factors underlie the eccentricity effect. They showed that the eccentricity effect cannot be accounted for by the peripheral reduction in visual sensitivity, peripheral crowding, or cortical magnification. Experiment 5 tested the attention allocation model and also showed that RT X set size effects can be independent of eccentricity effects. Experiment 6 showed that the effective set size in a search task depends, in part, on the eccentricity of the target because observers search from fixation outward. 相似文献

As life expectancy increases, interest has grown surrounding the factors that may influence quality of life (QOL) for people with cystic fibrosis (CF). The aim of the current study was to examine which specific coping styles were positively or negatively associated with social and emotional QOL in a CF sample. One hundred and twenty-two respondents aged 18 and over were recruited through an online support group. Respondents completed the ‘CF Questionnaire-Revised (CFQ-R)’ and the ‘Brief COPE’. The CFQ-R is a disease-specific instrument designed to measure the impact of CF on nine QOL domains and the Brief COPE is a 28 item questionnaire which assesses 14 coping scales. A multivariate regression model revealed that higher substance abuse and disengagement was associated with lower emotional QOL whereas greater use of religion, instrumental coping and acceptance was positively associated with emotional QOL. Active coping was linked to better social QOL and a negative association was reported between distraction coping with both emotional and social domains. Given the burden of CF, ascertaining which factors enhance or diminish emotion and social well-being is now an integral component of QOL research. The current findings may therefore have value in informing clinical interventions which aim to cater for the psychological needs of individuals with CF. 相似文献

The ability to inhibit unproductive motor responses triggered by salient stimuli is a fundamental inhibitory skill. Such motor self-regulation is thought to underlie more complex cognitive mechanisms, like self-control. Recently, a large-scale study, comparing 36 species, found that absolute brain size best predicted competence in motor inhibition, with great apes as the best performers. This was challenged when three Corvus species (corvids) were found to parallel great apes despite having much smaller absolute brain sizes. However, new analyses suggest that it is the number of pallial neurons, and not absolute brain size per se, that correlates with levels of motor inhibition. Both studies used the cylinder task, a detour-reaching test where food is presented behind a transparent barrier. We tested four species from the order Psittaciformes (parrots) on this task. Like corvids, many parrots have relatively large brains, high numbers of pallial neurons, and solve challenging cognitive tasks. Nonetheless, parrots performed markedly worse than the Corvus species in the cylinder task and exhibited strong learning effects in performance and response times. Our results suggest either that parrots are poor at controlling their motor impulses, and hence that pallial neuronal numbers do not always correlate with such skills, or that the widely used cylinder task may not be a good measure of motor inhibition. 相似文献

In a task requiring speeded bidirectional responses to arrow symbols (?,?), "free choice" responses to interspersed bidirectional stimuli (<>) are influenced by masked directional primes (e.g., Schlaghecken & Eimer, 2004). By varying stimulus-response (S-R) compatibility, we tested whether this priming effect is mediated by the conscious instructional set, or instead by pre-existing directional associations to the symbols. In two experiments, one group of participants was instructed to respond with the hand consistent with the implied direction of the arrow symbols, while another group was instructed to make the spatially opposite responses. Both groups showed priming of "free choice" responses. However, such priming was always biased according to the instructional set rather than pre-existing associations. Subliminal priming of "free choice" responses therefore depends on conscious task goals. 相似文献

This preliminary study investigated whether individual differences in performance on a difficult social perception task (determining the sex of shape normalized, line drawn dynamic faces) are related to sex of observer, scores on an empathy quotient and scores on a systemizing quotient. Performance in the face perception task (N = 60) was above chance, indicating that participants could judge the sex of the degraded facial stimuli from dynamic information alone. There was a trend for women to be more accurate in their judgments of target sex than men, but regression analyses indicated that EQ scores alone predicted performance on the task. This study suggests that empathy may mediate sex differences in face perception abilities, and potentially other tasks in social perception. 相似文献

A new questionnaire was constructed for the measurement of a hypothetical personality trait of ‘health care’, i.e. care and respect for the physical integrity of the body. It was found that the trait was a component of Cattell's self-sentiment factor. This yielded a new and more comprehensive self-sentiment questionnaire. The new questionnaire was validated by the demonstration of low scores in heroin addicts and alcoholics. Further investigation showed that the self-sentiment is highly correlated with P, of which it is best regarded as an additional expression. This result confirms the interpretation of P as the negative pole of a broad super-ego or socialization factor. 相似文献
