In four experiments, we investigated the effect of deleting specific features of letters on letter and word recognition in
the context of reading aloud. Experiments 1 and 2 assessed the relative importance of vertices versus midsegments in letter
recognition. Experiments 3 and 4 tested the relative importance of vertices versus midsegments in word recognition. The results
demonstrate that deleting vertices is more detrimental to letter and word identification than is deleting midsegments of letters.
These results converge with those of previous research on the role of vertices in object identification. Theoretical implications
for early processing in reading are noted. 相似文献

It is well known that the difference in performance between valid and invalid trials in the covert orienting paradigm (i.e., the cueing effect) increases as the proportion of valid trials increases. This proportion valid effect is widely assumed to reflect “strategic” control over the distribution of attention. In the present experiments we determine if this effect results from an explicit strategy or implicit learning by probing participant’s awareness of the proportion of valid trials. Results support the idea that the proportion valid effect in the covert orienting paradigm reflects implicit learning not an explicit strategy. 相似文献

Researchers have recently demonstrated that mind-wandering episodes can vary on numerous dimensions, and it has been suggested that assessing these dimensions will play an important role in our understanding of mind wandering. One dimension that has received considerable attention in recent work is the intentionality of mind wandering. Although it has been claimed that indexing the intentionality of mind wandering will be necessary if researchers are to obtain a coherent understanding of the wandering mind, one concern is that this dimension might be redundant with another, longstanding, dimension: namely, meta-awareness. Thus, the utility of the argument for assessing intentionality rests upon a demonstration that this dimension is distinct from the meta-awareness dimension. To shed light on this issue, across two studies we compared and contrasted these dimensions to determine whether they are redundant or distinct. In both studies, we found support for the view that these dimensions are distinct. 相似文献

Two experiments investigated the role that mental set plays in reading aloud using the task choice procedure developed by Besner and Care [Besner, D., & Care, S. (2003). A paradigm for exploring what the mind does while deciding what it should do. Canadian Journal of Experimental Psychology, 57, 311–320]. Subjects were presented with a word, and asked to either read it aloud or decide whether it appeared in upper/lower case. Task information, in the form of a brief auditory cue, appeared 750 ms before the word, or at the same time as the word. Experiment 1 yielded evidence consistent with the claim that at least some pre-lexical processing can be carried out in parallel with decoding the task cue (the 0 SOA condition yielded a smaller contrast effect than the long SOA condition). Experiment 2 provided evidence that such processing is restricted to pre-lexical levels (the word frequency effect was equivalent at the 0 SOA and the long SOA). These data suggest that a task set is a necessary preliminary to lexical processing when reading aloud. 相似文献

TheSimon effect refers to the observation that subjects identify targets (e.g., colors) faster when the irrelevant spatial location of the
target corresponds to the location of the response key. Theoretical accounts of the Simon effect typically explain performance
in terms of automatic and controlled processes. Furthermore, the relative contributions of automatic and controlled processes
are held to change as a function of the proportion of compatible to incompatible trials (compatibility proportion). Data are presented demonstrating that the reliability of the Simon effect, indexed by correlating its magnitude within
subjects across blocks of trials, varied substantially as a function of the compatibility proportion. When the compatibility
proportion was high, so was reliability. When the compatibility proportion was low, reliability was low as well. The results
are discussed in terms of the relative reliability of automatic and controlled processes and the role of working memory and
attentional control in goal maintenance. 相似文献

Paying attention to attention: evidence for an attentional contribution to the size congruity effect
Evan F. Risko Erin A. Maloney Jonathan A. Fugelsang 《Attention, perception & psychophysics》2013,75(6):1137-1147
Understanding the mechanisms supporting our comprehension of magnitude information represents a key goal in cognitive psychology. A major phenomenon employed in the pursuit of this goal has been the physical size congruity effect—namely, the observation that comparing the relative numerical sizes of two numbers is influenced by their relative physical sizes. The standard account of the physical size congruity effect attributes it to the automatic influence of the comparison of irrelevant physical magnitudes on numerical judgments. Here we develop an alternative account of this effect on the basis of the operation of attention in the typical size congruity display and the temporal dynamics of number comparison. We also provide a test of a number of predictions derived from this alternative account by combining a physical size congruity manipulation with a manipulation designed to alter the operation of attention within the typical size congruity display (i.e., a manipulation of the relative onsets of the digits). This test provides evidence consistent with an attentional contribution to the size congruity effect. Implications for our understanding of magnitude and the interactions between attention and magnitude are discussed. 相似文献

Visual exploration is driven by two main factors - the stimuli in our environment, and our own individual interests and intentions. Research investigating these two aspects of attentional guidance has focused almost exclusively on factors common across individuals. The present study took a different tack, and examined the role played by individual differences in personality. Our findings reveal that trait curiosity is a robust and reliable predictor of an individual's eye movement behavior in scene-viewing. These findings demonstrate that who a person is relates to how they move their eyes. 相似文献

AbstractThere exists a large body of work examining individual differences in the propensity to engage in reflective thinking processes. However, there is a distinct lack of empirical research examining the role of dispositional factors in these differences and understanding these associations could provide valuable insight into decision-making. Here, we examine whether individual differences in cognitive reflection are related to narcissism (excessive self-focused attention) and impulsiveness (trait-based lack of inhibitory control). Participants across three studies completed measures of narcissism, impulsiveness and cognitive reflection. Results indicate that grandiose and vulnerable narcissists differ in their performance on problem-solving tasks (i.e., Cognitive Reflection Test [CRT]) and preferences for intuitive thinking, as well as the degree to which they reflect on and understand their own thoughts and enjoy cognitively effortful activities. Additionally, though impulsiveness was significantly related to self-report measures of cognitive reflection (i.e., metacognitive reflection, metacognitive insight, and need for cognition), it showed no association with a behavioural measure of cognitive reflection (i.e., CRT scores). Our results suggest that certain individual differences in dispositional and personality characteristics may play important roles in the extent to which individuals engage in certain forms of reflective thinking. 相似文献
