Some Dare Call It Conspiracy: Labeling Something a Conspiracy Theory Does Not Reduce Belief in It

“Conspiracy theory” is widely acknowledged to be a loaded term. Politicians use it to mock and dismiss allegations against them, while philosophers and political scientists warn that it could be used as a rhetorical weapon to pathologize dissent. In two empirical studies conducted on Amazon Mechanical Turk, I present an initial examination of whether this concern is justified. In Experiment 1, 150 participants judged a list of historical and speculative theories to be no less likely when they were labeled “conspiracy theories” than when they were labeled “ideas.” In Experiment 2 (N = 802), participants who read a news article about fictitious “corruption allegations” endorsed those allegations no more than participants who saw them labeled “conspiracy theories.” The lack of an effect of the conspiracy‐theory label in both experiments was unexpected and may be due to a romanticized image of conspiracy theories in popular media or a dilution of the term to include mundane speculation regarding corruption and political intrigue.     

Self-Labeling Sexual Harassment

This study was designed to examine personal, stimulus, and organizational factors that predict the self-labeling of sexual harassment. Hypotheses were developed based on the social cognitive schema framework, which suggests that the activation of a victim's schema of sexual harassment influences self-labeling incidents as sexual harassment. Results of a secondary analysis of the 1995 Department of Defense Gender Issues dataset generally supported the hypotheses in that self-labeling is a multi-faceted process. Several findings were in the opposite direction from that predicted (e.g., perceptions that the military was implementing sexual harassment policies were negatively associated with self-labeling). Alternative explanations for the complexity of the self-labeling process were also examined. Portions of this article were presented as a poster at the 2000 Association for Women in Psychology conference in Salt Lake City, Utah. Authorship is listed alphabetically, both authors contributed equally to this study.     

语言标识对情绪体验的影响

本研究通过两个实验考察了语言标识对个体情绪体验的调节作用。实验一探讨了中性标识对不同类型的情绪体验的影响,结果发现与韩文字符标识相比,中性双字词标识时被试对负性图片的消极情绪体验强度显著降低。实验二进一步探讨了不同情绪色彩的词语的标识效应,结果发现与中性标识相比,负性或正性标识时被试对负性图片的消极情绪体验程度更低。结果表明了语言标识对负性情绪体验具有显著的调节作用,并且标识效应的产生依赖于词汇语义信息的通达。     

Hippocampus-dependent strategy choice predicts low levels of cell proliferation in the dentate gyrus

Neurogenesis continues to occur throughout life in the mammalian hippocampus. Previous research has suggested that the production of new neurons in the hippocampus during adulthood may be related to hippocampus-dependent learning and memory. However, the exact relationship between adult neurogenesis and learning and memory remains unclear. Here we investigated whether learning strategy selection is related to cell proliferation or to survival of new neurons in the hippocampus of adult male rats. We trained rats on alternating blocks of hippocampus-dependent (hidden platform) and hippocampus-independent (visible platform) versions of the Morris water task with the platform always in the same position. Following training, rats were given a probe session during which the platform was visible and in a novel location. Preferred strategy was determined by observing the initial swim path. Rats were classified as place strategy (hippocampus-dependent) users if they swam to the old platform location. Cue strategy (hippocampus-independent) users were classified as those rats that swam initially to the visible platform. Our results indicate that rats that preferentially used a place strategy had significantly lower cell proliferation than cue strategy users. However, there was no significant difference in cell survival or number of immature neurons between strategy user groups. These results suggest that low levels of cell proliferation in the dentate gyrus may be conducive or coincident with more efficient memory processing in the hippocampus.     

词汇的唤醒度对情绪标注效应的影响—ERPs研究

基于晚期阻断理论考察词汇唤醒度对情绪标注效应的影响,研究选择情绪面孔图片为实验材料,借助ERPs技术,以命名后的LPP波幅为指标,考察词汇的唤醒度对情绪标注效应的影响。结果发现：进行情绪标注时,与使用低唤醒度词相比,高唤醒度词条件下的LPP波幅更小;而进行非情绪标注时,差异不显著;无论词的唤醒度高或低,情绪标注与非情绪标注差异显著,情绪标注下LPP波幅更低。结果表明：进行情绪标注时,情绪词唤醒度越高抑制情绪的效果越好,而进行非情绪标注时则无影响;结果支持了晚期阻断理论。     

Comparison of two discrimination methods in teaching Chinese children with autism

In teaching conditional discriminations to children with autism spectrum disorder (ASD), practitioners may progress from simple to conditional discriminations or may teach conditional discriminations from the onset of instruction. Some research indicates that teaching simple discriminations first may be unnecessary and that teaching may more efficiently focus on conditional discriminations exclusively. This study replicated comparisons of simple-to-conditional and conditional-only discrimination training methods in teaching audio-visual conditional discriminations to Chinese preschoolers with ASD. Results indicated the conditional-only training method appeared to be more efficient in teaching these skills.     

Comparing structured mix and random rotation procedures to teach receptive labeling to children with autism

We compared two procedures using an alternating treatments design to teach receptive labeling to children with autism. The structured mix procedure followed seven steps entailing mass trials, intermixing, and random rotation. In the random rotation procedure, we trained all stimuli from the start. Study 1 included four children with a repertoire of four to 50 receptive labels and who primarily communicated with an alternative communication device. Results showed that the two conditions were comparable for one participant, structured mix was effective and random rotation was not effective for one participant, and that both conditions were ineffective for two participants. Study 2 included five children with over 200 receptive labels in their repertoire and with vocal speech as the primary form of communication. Four participants acquired the labels in both procedures, but random rotation was more effective. Results indicate that structured mix may be more effective for participants with a limited language repertoire and random rotation is more effective for participants with a larger language repertoire.     

To Add Insight to Injury: Childhood Abuse,Abuse Perceptions,and the Emotional and Physical Health of Young Adults

Although childhood abuse is strongly associated with psychological difficulties, survivors may not perceive their experiences as abusive. Depression, anxiety, dissociation, and physical health complaints may decrease perceptions of abuse and may also be exacerbated by individuals' abuse perceptions. The current study examined abuse perceptions, abuse experiences, and current symptoms among 185 university students. Ninety-six participants repeated the study 1–2 years later. At Time 1, self-labeling as “abused” or “maltreated” was not related to psychological or physical health symptoms. At Time 2, self-labeling as “abused” or “maltreated” was positively related to depression, anxiety, and dissociation. Results indicate that abuse perceptions may change over time and may be connected with emotional and physical symptoms.     

AN EVALUATION OF THE RELATIONSHIP BETWEEN RECEPTIVE SPEECH SKILLS AND EXPRESSIVE SIGNING

We examined the effects of receptive speech on the acquisition of manual signing among three mentally retarded children. In an alternating treatments design, we compared the acquisition of expressive signs that were, versus were not, in a child's receptive vocabulary. The children were trained via total communication in which pictorial referents were named during sign training. Signs corresponding to known words were generally acquired faster and retained better than signs corresponding to unknown words. We conducted posttests to assess the stimulus control of signing and any changes in expressive and receptive signing and speech. Observed changes in performance could be accounted for by attention to aspects of the stimulus complex during training and functional equivalence of stimuli established by training.     

Package Graphics and Consumer Product Beliefs

In recent years, marketers' tactics to increase product sales through health claims have been scrutinized by public policy makers. The culmination of this process was the passage of the National Labeling Education Act, which highly restricts the type, amount, and format of nutritional information conveyed on the package. In this investigation, we examine an under-explored aspect of the package—its colors and pictures—to determine what, if any, impact these aspects have on consumer beliefs regarding important product characteristics. We find that even when very concrete verbal information is used, graphical representations have a significant and long-term effect on product beliefs and purchase intentions.
