Computational models of lexical semantics, such as latent semantic analysis, can automatically generate semantic similarity
measures between words from statistical redundancies in text. These measures are useful for experimental stimulus selection
and for evaluating a model’s cognitive plausibility as a mechanism that people might use to organize meaning in memory. Although
humans are exposed to enormous quantities of speech, practical constraints limit the amount of data that many current computational
models can learn from. We follow up on previous work evaluating a simple metric of pointwise mutual information. Controlling
for confounds in previous work, we demonstrate that this metric benefits from training on extremely large amounts of data
and correlates more closely with human semantic similarity ratings than do publicly available implementations of several more
complex models. We also present a simple tool for building simple and scalable models from large corpora quickly and efficiently. 相似文献

The influence of pro‐ versus anti‐discrimination ingroup norms on Swiss nationals' attitudes towards foreigners was investigated as a function of national identification and perceived material ingroup threat. As predicted, results revealed a significant interaction between identification and threat: High identifiers showed a more negative attitude than low identifiers mainly when perceived threat was high. In other words, high identifiers conformed to the pro‐discrimination norm, but showed a counter‐conformity effect for the anti‐discrimination norm. Additional results revealed that high identifiers actually disagreed with the anti‐discrimination norm when perceived threat was high, but that they were more attached to the ingroup. These findings suggest that when the ingroup norm is not an appropriate response to an ingroup threat (i.e. anti‐discrimination norm), high identifiers find themselves in a loyalty conflict: they are unable to simultaneously conform to the group norm and protect the group. This conflict was resolved through a compensatory mechanism: High identifiers distanced themselves from the ingroup norm in order to protect the group (i.e. by increasing negative attitudes towards foreigners) but reinforced other ingroup ties (i.e. by increasing attachment to the ingroup values).

Labeling and the effects of labeling have been extensively researched in the psychological literature in a variety of different contexts. For example, labeling has been empirically shown to lead to lowered expectancies of behavior and achievement, which can then contribute to the potential for the occurrence of a self-fulfilling prophecy with adverse consequences. Another area that has been extensively researched, with a dramatic increase in the literature base in recent history, is that of child sexual abuse (CSA). Despite various shortcomings of the research literature, the consistent findings have been identification of a variety of negative correlates and symptomatologies associated with CSA. In addition to any direct, negative effects of CSA, there may also be an additional impact from the “label” itself. Although the literature pertaining to CSA and labeling runs deep independently, efforts at addressing the issue of CSA within a labeling contextual framework have been minimal. To that end, this article examines hypothesized mechanisms of how the “sexual abuse” label may potentially have an adverse influence on the children subjected to such a label. The implications of an analysis, which addresses childhood sexual abuse from such a theoretical framework, may be a broader and more holistic understanding of the complexities and sequelae associated with CSA. 相似文献

The present study (N = 293) examined whether stereotype endorsement and prejudice moderate stereotype lift (i.e., a performance boost caused by the salience of a negative out-group stereotype in the testing situation). The stereotype in the focus of inquiry was the belief that immigrant students have lower intellectual ability than native students. French native high school students performed an intellectual test in a condition of low stereotype salience (the test was presented as assessing individual differences) or in a condition of high stereotype salience (the test was presented as assessing group differences between African immigrants and native students). As expected, results indicated that native students high in stereotype endorsement and those high in prejudice performed better in the high than in the low stereotype salience condition, whereas those low on these constructs did not. By identifying two moderators of stereotype lift, this study sheds new light on the achievement gap between immigrant and native students in educational institutions. 相似文献

This article provides a normative study documenting how 75 Danish nonpatient 9-year-old children respond to the Rorschach test. The children were selected randomly from nine different parts of Denmark and tested with the Rorschach by 10 different psychologists. All examiners were familiar with the Comprehensive System (CS; Exner, 2003), and before the data collection they participated in a 3-day workshop performed by the research group that focused on administration, inquiry, and scoring issues. Among the results are an average R of 23.6 and an average Lambda of 2.01 (median = 1.18). Slightly more than 60% of the sample had an Avoidant style (63%); 41% had a CDI of 4 or 5; and 33% were positive on the HVI. In terms of perception and thinking, average values were .44 for X+%, .27 for X-%, and 9.4 for the WSum6. 相似文献

Two experiments examined the task interference that sometimes accrues from having an intention. In standard prospective memory
tasks, latency is often slower to an ongoing task performed concurrently with having an intention than it is when no intention
is given. If the locus of this slowing resulted from different attentional allocation policies in the two cases, we predicted
that the process of learning a word list would be impaired if participants had an intention rather than if they did not. Four
different event-based prospective memory tasks were used in Experiment 1 to demonstrate that worse free recall of a word list
resulted when studied with a concurrent intention than with a control condition that had no intention. In that experiment,
linking an intention to a distal context that was to occur after learning did not impair free recall. Two time-based tasks
were used in Experiment 2 to demonstrate that possessing a time-based prospective memory also hinders learning, unless the
intention is linked to a future context that is expected to occur after the study session. In the latter case, no impairment
was obtained. 相似文献

Over the past several years, a number of studies have been done that assess processing at the level of the situation model
in relation to issues of aging (Morrow, Leirer, & Altieri, 1992; Radvansky, Copeland, Berish, & Dijkstra, 2003; Radvansky,
Copeland, & Zwaan, 2003; Stine-Morrow, Gagne, Morrow, & DeWall, 2004; Stine-Morrow, Morrow, & Leno, 2002). In contrast to
age-related declines that have been demonstrated at surface form and textbase levels of processing, no such declines have
been found in the creation and updating of situation models (Radvansky, 1999). This review focuses on the relevant factors
in cognitive aging and situation model processing and places them within the larger frameworks of language processing, working
memory capacity, and aging. 相似文献

This research extends past work on positive illusions and self-goals by examining motivated perceptions of how much control people think they have over changing their personality traits. A self-validation motivation should cause individuals to view their personality weaknesses as uncontrollable (to avoid blame for having them) and their personality strengths as controllable (to take credit for having them). A self-growth motivation should cause individuals to view their weaknesses as controllable (to view them as improvable) and their strengths as uncontrollable (to view them as unchanging). Studies 1 and 2 find evidence for self-validation in perceptions of trait controllability. Study 3 finds this pattern to be stronger for validation-seeking individuals but weaker for growth-seeking individuals. Studies 3 and 4 find that being primed with one's successful self-improvements or one's future self can attenuate the self-validation. The potential implications of distorted perceptions of trait controllability for both well-being and self-change are discussed. 相似文献
