A brighter side to memory illusions: false memories prime children's and adults' insight-based problem solving

Can false memories have a positive consequence on human cognition? In two experiments, we investigated whether false memories could prime insight problem-solving tasks. Children and adults were asked to solve compound remote associate task (CRAT) problems, half of which had been primed by the presentation of Deese/Roediger-McDermott (DRM) lists whose critical lures were also the solutions to the problems. In Experiment 1, the results showed that regardless of age, when the critical lure was falsely recalled, CRAT problems were solved more often and significantly faster than problems that were not primed by a DRM list. When the critical lure was not falsely recalled, CRAT problem solution rates and times were no different from when there was no DRM priming. In Experiment 2, without an intervening recall test, children and adults still exhibited higher solution rates and faster solution times to CRAT problems that were primed than to those that were not primed. This latter result shows that priming occurred as a result of false memory generation at encoding and not at retrieval during the recall test. Together, these findings demonstrate that when false memories are generated at encoding, they can prime solutions to insight-based problems in both children and adults.     

An Exploration of the Content of Stereotypes of Black Politicians

Do voters have the same stereotypes of Black politicians that they have of Black people in general? We argue that common stereotypes of Blacks (e.g., lazy, violent) may not apply to perceptions of Black politicians. Instead, we hypothesize that Black politicians are a unique subtype of the larger group Blacks, different enough to warrant their own stereotypes. We take an inductive approach to understanding the stereotypes of Black politicians. Employing a classic psychology research design ( Katz & Braly, 1933 ) in which respondents list traits for a target group, we find that there is little overlap of stereotype content between Black politicians and Blacks. Our results therefore indicate that Black politicians constitute a separate and unique subtype of Blacks. Our analysis explores similarities and differences between stereotypes of Black politicians and two other groups: Black professionals (another subtype of Blacks) and politicians. We discuss the implications of our findings for the relationship between stereotypes and voter decisions.     

Age-independent effects of pubertal status on behavioral constraint in healthy adolescents

Studies have examined age-related changes in personality traits from adolescence through young adulthood, finding that aspects of negative emotionality decrease while conscientiousness increases over time. Varied mechanisms may underlie these transitions, including puberty-driven hormonal changes. Here, healthy adolescents completed the Multidimensional Personality Questionnaire-Brief Form and self-report measures of pubertal status at baseline and after two years. Independent of age, pubertal status impacted primary trait scales of the MPQ-BF Constraint factor in a sex-specific manner. Females decreased in Constraint, and particularly Control, while males increased in Constraint, and particularly Harm Avoidance, with advancing puberty. Longitudinal analyses validated these findings for Control. Findings are discussed relative to males’ versus females’ achievement of optimal levels of behavioral control in adolescence.     

Sexualized images in professional contexts: Effects on anticipated experiences and perceived climate for women and men

Academic conferences are important settings for socialization, scholarly engagement, and networking. Two studies explore the effects of ambient cues in such settings on women's and men's climate perceptions. Participants (undergraduates in Study 1, graduate students in Study 2) viewed a flyer advertising a professional mixer that included an eroticized image or a control image. Women and men expected a sexualized atmosphere, and women in particular anticipated lower feelings of competence and greater discomfort and objectification at the event advertised with the erotic image. The negative effect of erotic flyer exposure on competence was mediated by discomfort (Study 1) and objectification (Study 2), particularly in women. Results are interpreted in light of pipeline leakage and women's success in the Academy.     

Extrapolating spatial layout in scene representations

Can the visual system extrapolate spatial layout of a scene to new viewpoints after a single view? In the present study, we examined this question by investigating the priming of spatial layout across depth rotations of the same scene (Sanocki &; Epstein, 1997). Participants had to indicate which of two dots superimposed on objects in the target scene appeared closer to them in space. There was as much priming from a prime with a viewpoint that was 10° different from the test image as from a prime that was identical to the target; however, there was no reliable priming from larger differences in viewpoint. These results suggest that a scene’s spatial layout can be extrapolated, but only to a limited extent.     

Developmental changes in dopamine neurotransmission in adolescence: Behavioral implications and issues in assessment

Adolescence is characterized by increased risk-taking, novelty-seeking, and locomotor activity, all of which suggest a heightened appetitive drive. The neurotransmitter dopamine is typically associated with behavioral activation and heightened forms of appetitive behavior in mammalian species, and this pattern of activation has been described in terms of a neurobehavioral system that underlies incentive-motivated behavior. Adolescence may be a time of elevated activity within this system. This review provides a summary of changes within cortical and subcortical dopaminergic systems that may account for changes in cognition and affect that characterize adolescent behavior. Because there is a dearth of information regarding neurochemical changes in human adolescents, models for assessing links between neurochemical activity and behavior in human adolescents will be described using molecular genetic techniques. Furthermore, we will suggest how these techniques can be combined with other methods such as pharmacology to measure the impact of dopamine activity on behavior and how this relation changes through the lifespan.     

Conflicted Gender Identity, Body Dissatisfaction, and Disordered Eating in Adult Men and Women

The relation between gender identity and body dissatisfaction as well as disordered eating was examined in a population-based sample of Finnish adults aged 18 to 44 years (N?=?1,142). Participants with a conflicted gender identity were compared to controls matched on age and biological sex. Participants with a conflicted gender identity showed higher levels of body dissatisfaction, women with a conflicted gender identity also showed more eating disturbance than controls. Among men with a conflicted gender identity, male–male sexual experience was associated with more body dissatisfaction and disordered eating. Among women with a conflicted gender identity, female–female sexual experience was related to less body dissatisfaction. Possible explanations for these findings and the potential clinical implications are discussed.     

“清代道藏”——江南蒋元庭本《道藏辑要》之研究

继明代《正统道藏》之后,《道藏辑要》是最重要的道教丛书。《道藏辑要》一书的形成至今仍是个谜,当代学者普遍认为它有三个主要版本:一为彭定求(1645-1719)编原本,二为蒋元庭(1755-1819)增补本,三为贺龙骧、彭瀚然最终修订本。与学者们普遍认可的观点不同,本文力图证明《道藏辑要》实际上只有两个版本(版本二和版本三),而所谓的彭定求本纯属虚构。在对蒋元庭之同代人闵一得(1748/58-1836)的作品进行研究后,我们证实蒋元庭确是《道藏辑要》的编者。在闵一得的作品中,我们还可以发现《道藏辑要》在江南地区与"吕洞宾崇拜"有关之道教社团中的影响;在巴黎藏本《道藏辑要》(这一版本与藏书家丁福保编制目录之版本十分近似)中,这种影响的痕迹更是十分明显。在此发现的基础上,本文力图开辟新的研究领域,使读者可以更好地了解《道藏辑要》的复杂文本历史,以及它在推动清代道教纯粹远景及扶鸾崇拜中的角色。     

Death Qualification as Systematic Exclusion of Jurors With Certain Religious and Other Characteristics

The death‐qualification process has been criticized because it tends to eliminate certain groups of individuals at a higher rate than others. This study examined whether the process systematically excludes jurors based on religious characteristics, justice philosophy, cognitive processing, and demographics. Results indicated that death qualification can be predicted by religious affiliation, devotionalism, fundamentalism, and Biblical interpretism; but not evangelism. Death qualification is predicted by the belief that murderers deserved to die, but not by beliefs that criminals deserve mercy, forgiveness, or payback. Cognitive processing had no impact on death qualification. Finally, gender and race predicted death qualification, while age and prior jury duty did not. These results are discussed in terms of implications for perceived legitimacy of the system.     

Training and testing music skills in a boy with autism using a matching‐to‐sample format

A 16‐year old boy with autism was taught music skills using a matching to sample procedure. He was trained and subsequently tested for the formation of four 4‐member classes, including different visual music stimuli, and Norwegian and Vietnamese labels for different major and minor chords. Four different stimuli sets were trained both in one‐to‐many (OTM) and many‐to‐one (MTO) training structures. Further, we explored if the reaction times to comparison stimuli increased from training to testing. Results showed that the participant formed equivalence classes with music relations. Furthermore, there were small differences only between OTM and MTO with respect to stimulus equivalence responding. The reaction times to comparison stimuli increased from training to testing, and were most pronounced for the equivalence trials. Copyright © 2010 John Wiley & Sons, Ltd.
