Factors affecting word retrieval were compared in a timed picture-naming paradigm for 520 drawings of objects. In prior timed
and untimed studies by Snodgrass and Vanderwart (1980) and Snodgrass and Yuditsky (1996), concerns were raised that participants
could not reliably name large numbers of items in a single session. We show that reliable results are obtained in a single
session for 520 items and validate our method against previous findings by Snodgrass and colleagues for overlapping items.
For these items, comparable levels of name agreement and latency are obtained, and we replicate effects of length, frequency,
both objective and subjective age of acquisition, and visual complexity on reaction time (RT) and name agreement measures.
Name agreement is unaffected by order of presentation, although there is a gradual increase in RTs across the session, requiring
use of multiple random orders. Current extensions of our method include cross-linguistic, bilingual, developmental, and neuropsychological
studies and comparisons of action naming and object naming. 相似文献

Hemispheric asymmetry in lexical decisions: the effects of grammatical class and imageability 总被引:1,自引:0,他引:1
It has been suggested that neural systems for lexical processing of nouns and verbs are anatomically distinct. The aim of the present study was to investigate if brain asymmetry for the processing of these two grammatical classes is also different. Neurologically intact adults performed a lateralized lexical decision task with grammatically unambiguous words of high, medium, and low degrees of imagery. For error scores a right visual field (RVF) advantage and an overall effect of imageability were obtained. For latency scores grammatical class and imageability modified visual field differences: in the noun class a RVF advantage was obtained only for low imagery nouns, while for the verbs the RVF advantage was present for both medium and low imagery verbs. These results suggest that the participation of right hemisphere neural systems in the processing of verbs is more limited than in the processing of nouns. 相似文献

Inhibition of return and the attentional set for integrating versus differentiating information. 总被引:10,自引:0,他引:10
Cuing a location with an uninformative cue leads to a facilitatory effect at that location shortly afterward and later (about 300 ms) to a negative effect called inhibition of return (IOR). Until recently, it was argued that IOR occurs in detection and localization tasks, but not in discrimination tasks. However, the authors of several recent studies have demonstrated IOR effects in discrimination tasks, although at a later cue-to-target stimulus onset asynchrony (SOA). In this study, the authors examined why IOR occurs at a later SOA in discrimination tasks. In Experiments 1 and 2, different time courses of exogenous cuing effects in detection and discrimination tasks were established. In Experiment 3, the authors examined the role of an attentional set on the time course of exogenous cuing effects by manipulating the proportion of trials in which a distractor is presented in the location opposite the target. A new framework for understanding exogenous cuing effects and their dependence on endogenous attention is proposed. 相似文献

Green and Salovey agree with us that happiness and sadness are strongly bipolar, and that Positive and Negative Activation are not. However, Green and Salovey subscribe to the two-dimensional circumplex, a model we find wanting. Actually, the problems they discuss arise from the limitations of the circumplex rather than from issues fundamental to affective structure. And they do not consider the evidence, reported in our target article, that supports an alternative to the circumplex: a three-level hierarchical model. In this reply, we take a closer look at the empirical findings supporting this model, and we emphasize its heuristic promise. 相似文献

This study was aimed at the examination of ‘mental construction’ in paradise fish by interactive learning, which is suggested
as an alternative hypothesis for backward or second-order conditioning. Avoidance of goldfish was established in paradise
fish by presenting a harmless goldfish (a novel stimulus) after an aversive event (mild electric shocks) in the dark compartment
of a shuttle tank. It was found that this avoidance depended on context pre-exposure. Experiment 1 was designed to study the
effect of mild shocks on shuttling activity in a familiar context. Experiment 2 aimed at establishing fear-conditioning to
the goldfish in a higher-order conditioning paradigm. In the course of training, unpaired stimuli were presented in the dark
compartment of the shuttle tank in such a manner that the presentation of mild shocks (20 mA) preceded the encounter with
a harmless fish (goldfish). Experiment 3 demonstrated the role of context pre-exposure in interactive learning. Results indicate
that (1) while 60 mA shocks resulted in avoidance of the dark compartment, the 20 mA mild shocks affected exploratory behaviour;
(2) after pre-exposure to the training environment, paradise fish avoided the dark compartment containing goldfish provided
that subjects had previously encountered mild, explorative shocks there; (3) this conditioned fear, a ‘mental construction’
of a potential danger, was proved to be transferable to another context and was consequently aimed specifically at the goldfish,
a living being, rather than the training context; (4) the pre-exposure to the shuttle tank was an important part of this training
procedure, that is, only subjects habituated to the shuttle tank avoided the goldfish. Results are discussed in the framework
of the Interactive Learning Hypothesis, which has been developed as an ethological approach to a higher-order conditioning
paradigm.

Analysis of 1998 statistics for individual performance in the PGA European Tour yielded significant differences between some shot-making skills (drive distance, total driving, greens in regulation, and sand saves) between the top 10 and bottom 10 money winners, replicating (with partially different results) a result found for the 1995 American PGA Tour by Engelhardt. 相似文献

Competition strongly affects individual effort and performance for both individuals and groups. Especially in work settings, these effort gains might come at the cost of individual well‐being. The present study tested whether competition increases both effort (as indicated by task performance) and stress (in terms of cardiovascular reactivity and affective response), and whether this effect is further qualified by the type of competition (interindividual vs. intergroup), using a cognitive computer‐based task and a 2 (Group: Yes, No) × 2 (Competition: Yes, No) × 2 (Gender) factorial design (N= 147). All participants either worked as a representative of a group or as an individual, and were offered performance‐related incentives distributed in a lottery. In the competition conditions, participants were informed that they competed with someone else, and that only the winning person/team would take part in the lottery. Consistent with expectations, competition increased both individual effort and cardiovascular reactivity compared to non‐competitive work. Moreover, for female participants, intergroup competition triggered increased effort and more positive affect than interindividual competition. Aside from documenting costly side‐effects of competition in terms of stress, this study provides evidence for a stress‐related explanation of effort gains during intergroup competition as compared to interindividual competition. 相似文献

Most creativity techniques encourage breaking away from stored knowledge and known solutions. Counter to this approach, this study assessed the effectiveness of an intervention based on introducing minimal variations to well-established knowledge structures. Two groups were tasked with generating creative metaphorical titles for short essays. While the experimental group had been trained in extending and reinstantiating conceptual metaphors, the control group had been trained on creativity techniques unrelated to the task. Training increased the number of novel metaphorical titles derived from conceptual metaphors, and these titles were more creative than novel metaphorical titles not derived from conceptual metaphors. Finally, the titles generated via the deliberate use of the trained heuristics were as creative as those of the same type that were spontaneously produced by the control group. The implications for interventions to promote creativity are discussed. 相似文献
