初中生社会比较在成就目标与学业自我效能感之间的中介效应

采用成就目标定向、社会比较和学业自我效能感三个量表,以724名初中生为被试,对社会比较在成就目标与学业自我效能感之间的中介作用进行了考察。结果表明：（1）除对学习能力自我效能感产生直接影响外,掌握接近目标会通过上行比较、成绩接近目标会通过上行/下行比较间接地影响学习能力自我效能感;（2）掌握接近目标、成绩接近目标和成绩回避目标不仅会对学习行为自我效能感产生直接影响,还会通过下行比较对其产生间接影响。说明成就目标可以通过直接和间接两种不同的方式影响学业自我效能感。     

不同情绪状态下自动表达抑制对情绪及表情知觉敏感性的影响

以103名大学生为对象,在正性、负性两种情绪状态下,用句子整理任务引发被试抑制情绪或表达情绪两种情绪调节方式,采用信号检测论测得正、负性表情的表情知觉敏感性。结果表明：（1）表情知觉敏感性存在情绪一致性效应,在负性情绪状态下,人们对负性表情更敏感,差异显著（p=0.002）;在正性情绪状态下,人们对正性表情更敏感,虽然只是边缘显著（p=0.700）。（2）自动抑制情绪会降低人们的情绪体验,并且会影响表情知觉敏感性的情绪一致性效应。在自动抑制启动的状态下,人们对正、负性表情都不太敏感。     

Impact of retailer image on private brand attitude: Halo effect and summary construct

The purpose of this article is to examine the influence of retailer image on consumers' attitude towards private brand. More specifically, we evaluate two alternative perspectives of retailer image—the halo effect and the summary construct—and include a moderator variable, consumer familiarity with a retailer's private label products, to discern which of the two models has better explanatory power. The findings indicate that there are moderating effects of consumer familiarity with a retailer's private brands and product categories in determining the efficacy of each model. In private brand foods, high familiarity is related to the summary construct model, and low familiarity is associated with the halo effect model. In private brand clothing, however, low familiarity is related to the halo effect model, but high familiarity is associated with both the halo effect and the summary construct model. Managerial and future research implications are also provided.     

Seeking positive experiences can produce illusory correlations

Individuals tend to select again alternatives about which they have positive impressions and to avoid alternatives about which they have negative impressions. Here we show how this sequential sampling feature of the information acquisition process leads to the emergence of an illusory correlation between estimates of the attributes of multi-attribute alternatives. The sign of the illusory correlation depends on how the decision maker combines estimates in making her sampling decisions. A positive illusory correlation emerges when evaluations are compensatory or disjunctive and a negative illusory correlation can emerge when evaluations are conjunctive. Our theory provides an alternative explanation for illusory correlations that does not rely on biased information processing nor selective attention to different pieces of information. It provides a new perspective on several well-established empirical phenomena such as the ‘Halo’ effect in personality perception, the relation between proximity and attitudes, and the in-group out-group bias in stereotype formation.     

The good, the strong, and the accurate: preschoolers' evaluations of informant attributes

Much recent evidence shows that preschoolers are sensitive to the accuracy of an informant. Faced with two informants, one of whom names familiar objects accurately and the other inaccurately, preschoolers subsequently prefer to learn the names and functions of unfamiliar objects from the more accurate informant. This study examined the inference process underlying this preference. We asked whether preschoolers make narrow inferences about informants, broader trait-based inferences, or more global evaluative inferences. We further asked what inferences preschoolers make about a potential informant based on distinctions in the unrelated domain of physical strength. The results indicate that preschoolers make relatively narrow inferences when observing individual differences in accuracy even though they are prone to global evaluative inferences when observing individual differences in strength. Preschoolers’ burgeoning understanding of others as expert language users may underlie their selective endorsement of a more accurate informant.     

Whatever Gave You That Idea? False Memories Following Equivalence Training: A Behavioral Account of the Misinformation Effect

The misinformation effect is a term used in the cognitive psychological literature to describe both experimental and real-world instances in which misleading information is incorporated into an account of an historical event. In many real-world situations, it is not possible to identify a distinct source of misinformation, and it appears that the witness may have inferred a false memory by integrating information from a variety of sources. In a stimulus equivalence task, a small number of trained relations between some members of a class of arbitrary stimuli result in a large number of untrained, or emergent relations, between all members of the class. Misleading information was introduced into a simple memory task between a learning phase and a recognition test by means of a match-to-sample stimulus equivalence task that included both stimuli from the original learning task and novel stimuli. At the recognition test, participants given equivalence training were more likely to misidentify patterns than those who were not given such training. The misinformation effect was distinct from the effects of prior stimulus exposure, or partial stimulus control. In summary, stimulus equivalence processes may underlie some real-world manifestations of the misinformation effect.     

Information quality in personality judgment: The value of personal disclosure

We examined the relative quality of different types of information and its effects on accuracy in personality judgment. Three hundred and forty-four unacquainted undergraduates participated in a small group round-robin rating scheme. In one condition, participants were asked to disclose three things that were very important to them in life. In a second condition, participants were asked to disclose three distinctive personal facts: things that differentiated them from others. We found that (a) people believed values information was more personality-relevant than facts information and (b) although there was no clear advantage for one condition over the other in terms of generalized accuracy, there were some differences across conditions for specific traits. Implications for the study of information quality in personality judgment are discussed.     

Students with the initial “A” don’t get better grades

It has been claimed that students whose first or last name begins with the letters A or B have higher grade point averages than students whose first or last name begins with the letters C or D. We critique the analysis behind this claim, raising a number of issues that lead us to question the validity of the claim. We also test for a relation between student initial and GPA using two new datasets and find no evidence to support such a relation.     

Analysis of five cases with neurogenic stuttering following brain injury in the basal ganglia

This study examined stuttering patterns in five patients with basal ganglia injury. None of the patients had a history of developmental stuttering. Four patients were right-handed; one patient was ambidextrous. Stuttering tests administered to patients assessed sentence repetition, reading aloud, explanations of a comic strip, and conversation. Accessory behaviors such as facial grimaces, associated movements of the limbs, and avoidance behaviors were observed. The results of this study differ from those of previous studies of neurogenic stuttering in several respects: (1) blocks were frequently observed. (2) Adaptation was observed. (3) Almost all stuttering occurred at the initiation of words. (4) Across patients, stuttering frequency did not vary in a consistent manner with speaking task. New speech characteristics for neurogenic stuttering without aphasia following injury to the basal ganglia are described.Educational objectives: After reading this text, the reader will be able to: (1) provide characteristics of neurogenic stuttering after the basal ganglia in patients without aphasia; (2) discuss the difference of the features and characteristics of stuttering between previously reported patients and present patients.     

The Flynn effect puzzle: A 30-year examination from the right tail of the ability distribution provides some missing pieces

The Flynn effect is the rise in IQ scores across the last eighty or more years documented in the general distribution of both industrialized and developing nations primarily on tests that require problem solving and non-verbal reasoning. However, whether the effect extends to the right tail (i.e., the top 5% of ability) remains unknown. The present study uses roughly 1.7 million scores of 7th-grade students on the SAT and ACT as well as scores of 5th- and 6th-grade students on the EXPLORE from 1981 to 2010 to investigate whether the effect operates in the right tail. The effect was found in the top 5% at a rate similar to the general distribution, providing evidence for the first time that the entire curve is likely increasing at a constant rate. The effect was also found for females as well as males, appears to still be continuing, is primarily concentrated on the mathematics subtests of the SAT, ACT, and EXPLORE, and operates similarly for both 5th and 6th as well as 7th graders in the right tail. These findings help clarify the nature of the effect and may suggest ways that potential causes can now be more meaningfully offered and evaluated.
