Recent evidence indicates that central directional stimuli, such as eyes and arrows, trigger rapid, reflexive shifts of spatial attention. A study by Fischer, Castel, Dodd, and Pratt (2003) suggested that a similar effect might also apply to central numbers, as if a digit's meaning causes attention to be oriented to its relative position on a left-to-right mental number line. However, unlike central eyes and arrows, the orienting effect for central digits emerges slowly, suggesting that top-down endogenous processes may be mediating this effect. Here, we report a series of three experiments that strongly support this hypothesis. Experiment 1 replicated Fischer et al.'s left-to-right number line effect. Experiment 2 showed that this effect could be completely reversed by merely asking participants to imagine a number line running from right to left. Experiment 3 showed that a left-to-right number line effect could be abolished by presenting targets above and below central fixation, as well as to the left and right of center. Experiment 3 also showed that other mental sets, such as imagining a clock, result in attention's being oriented in accordance with where the central digits are represented on a clock face. Together, these data indicate that the spatial representations and attentional orienting related to the perception of digits are both fragile and flexible and depend critically on the top-down spatial mental sets adopted by individuals. 相似文献

Two experiments provided new measures of switch cost and retrieval time in the task span procedure. In Experiment 1, subjects
were given lists of six task names to remember, followed by six targets on which to perform the tasks named in the list. The
lists contained alternations and repetitions, and switch costs were estimated by comparing reaction time (RT) on alternation
and repetition trials. The experiment also included memory span and single task conditions, so switch costs could be estimated
by subtracting the sum of the RT in those conditions from the task span RT, as in the original report (Logan, 2004). The data
suggested that the original measure of switch cost was invalid and that the new measure was preferable. In Experiment 2, subjects
performed each task on the list twice. Retrieval was required on the first but not on the second trial in each pair. Retrieval
time was estimated by comparing the RT on trials that required retrieval with trials that did not require retrieval. This
measure was more valid than the RT in the memory span condition of Experiment 1, which was used in the original report. 相似文献

This study investigates sex and race differences in normative beliefs about the acceptability of aggression across dimensions of severity of provocation (weak versus strong) and sex of provoker (male versus female). Students in the sample of 311 included those required to attend three Department of Youth Services schools after placement by the juvenile court system from across the state of Alabama (N=392). Results show that males were significantly more likely than females to approve of retaliation to weak provocation and against females. There were no significant differences between males and females for retaliation with strong provocation and against males. Results also show the Black group was significantly more likely than the White group to approve of retaliation to weak provocation, strong provocation, and against females. 相似文献

In this study, we examined the hypothesis that semantic judgment tasks share overlapping processes if they require processing on common dimensions but not if they require processing on orthogonal dimensions in semantic space (Osgood, Suci, & Tannenbaum, 1957). We tested the hypothesis with the implicit association test (IATl Greenwald, McGhee, & Schwartz, 1998) in three experiments. Consistent with the hypothesis, IAT effects (costs in reaction time because of incompatible response mapping between associated judgment tasks) occurred consistently when judgment tasks tapped into common semantic dimensions, whereas no IAT effect appeared when judgment tasks entailed processing on orthogonal semantic dimensions. 相似文献

The present study provides a data-driven approach to identifying groups of schools based on the concentration of at-risk students the school serves. The percentage of English language learners, minority students, and students eligible for free or reduced priced lunch were used as indicators in a latent profile analysis of 569 schools. The goal of the present study was to determine whether school-level average student reading performance varied as a function of the groups identified in the latent profile analysis. To do so, groups extracted by the latent profile analysis were used as school-level predictors of growth in oral reading fluency, which was modeled at the within-student level of a three-level hierarchical growth curve model. Oral reading fluency was measured at four points during the year in a large cross-sectional sample of first-, second-, and third-grade students. Results indicated that schools were able to be classified into four distinct groups based on their concentrations and types of at-risk students. Further, in all three grades, there were significant differences between the four identified groups observed in average reading fluency scores at the beginning of the year, the end of the year, and growth during the year indicating that groups based on school-concentration of at-risk students were significantly related to average student achievement in reading ability. 相似文献

Two matching-to-sample (MTS) and four same/different (S/D) experiments employed tests to distinguish between item-specific learning and relational learning. One MTS experiment showed item-specific learning when concept learning failed (i.e., no novel-stimulus transfer). Another MTS experiment showed item-specific learning when pigeons’ novel-stimulus transfer decreased because they chose familiar training comparisons instead of matching novel comparisons. In 8-item and 3-item S/D tasks, pigeons and monkeys were accurate with unfamiliar training-stimulus pairings, stimulus inversions, and distorted stimuli, suggesting relational learning within a domain restricted to the training stimuli (i.e., no novel-stimulus transfer). In 32-item S/D tasks, pigeons with previous 8-item training showed less transfer than those without prior training, suggesting a carryover of restricted-domain relational learning. Pigeons shifted from 1024-item to 8-item S/D tasks showed reinstatement of restricted-domain relational learning. These findings are important in specifying which types of learning occur in these tasks, showing that subjects failing novel-stimulus transfer are not required to switch from item-specific to relational learning as a training set is expanded, and demonstrating that concept learning failure is not proof of item-specific learning. 相似文献

Depression and Social Anxiety in Children: Differential Links with Coping Strategies 总被引:1,自引:0,他引:1

Strategies that children use for coping with stressors are known to be related to emotional adjustment, but not enough is
understood about specific links with social anxiety and depression. The present investigation tested differentiated associations
of social anxiety and depression with specific types of coping strategies, and evaluated the direction of these associations
over time. In Study 1, 404 children aged 8–13 years completed a coping scale modified from Kochendefer-Ladd and Skinner (Developmental Psychology 38:267-278, 2002) in order to evaluate factor structure and subscale internal consistency. In Study 2, 270 8–11-year-old children completed depression and social anxiety scales, a sociometric survey, and the coping scale from
Study 1, with a follow-up timepoint 9 months later. In Study 1, factor analysis revealed six internally consistent coping subscales. In Study 2, social anxiety and depression were found to have distinctive longitudinal associations with subsequent coping strategies.
Decreased problem-solving, social support-seeking, and distraction were uniquely predicted by depression but not by social
anxiety. Internalising coping was a stronger outcome of social anxiety, and increased externalising was uniquely predicted
by depression. There was also some evidence for a moderating role of peer relations. However, none of the coping strategies
predicted changes in depression or social anxiety over the two timepoints. These results highlight the impact that emotional
adjustment may have on children’s coping strategies, and clarify important distinctions between social anxiety and depression
in relation to coping. 相似文献

When two or more people witness an event together, the event report from one person can influence others’ reports. In the current study we examined the role of age and motivational factors on peer influence regarding event reports in adolescents and young adults. Participants (N=249) watched a short video of a robbery then answered questions with no co-witness information or with information believed to be from a co-witness. Public and private response conditions were included to explore motivations for peer influence. Co-witness information influenced participants’ responses, although the effect was equally strong in the private and the public co-witness conditions. Peer influence on event reports was steady across a large age range (11- to 25-year-olds). 相似文献
