Differentiating sexual preference in men: Using dual task rapid serial visual presentation task

Cognition research suggests that allocating attention resources to evolutionarily relevant stimuli is facilitated suggesting that sexual stimuli interfere with human information processing. In a group of gay (n = 13) and straight men (n = 13) recruited in Finland, Germany and Italy, we investigated if and how sexually relevant visual stimuli affect information processing of both a target one (T1) and a subsequent target two (T2) in a dual target rapid serial visual presentation procedure. We hypothesized that: (1) due to the attentional blink (AB) phenomenon, the accuracy of reporting of T2 would decrease when following accurately identified sexually preferred T1 compared to accurately identified non‐sexually preferred T1; 2) due to the pop out effect, the accuracy of reporting of T1 and T2 would be relatively increased when T1 and T2 were sexually preferred by the participants compared to when they were not. Our findings did not support hypothesis 1 but supported hypothesis 2. We further found that the pop out effect had a good capacity to differentiate sexual preference between the groups of gay and straight men. We conclude that dual target rapid serial visual presentation can be used as an attention‐based measurement to differentiate sexual preference in men. Limitations and the applicability in the field of measuring sexual preference were discussed.     

娃娃脸效应：对婴儿面孔的偏好及过度泛化

娃娃脸效应是指由婴儿面孔特征(或婴儿图式)所引发的普遍、进化的社会认知反应, 不仅包括对婴儿面孔的偏好性反应—— 如优先注意、关怀和照料的冲动, 还包括对于具备婴儿图式的成年人、动物甚至非生命物体的泛化性反应, 即认为这些对象具有与婴儿相似的特质并对其产生相应的态度和行为。娃娃脸效应的表现、影响因素及神经机制的相关研究证明了人类对于婴儿面孔特征的偏好性反应是一种本能释放机制, 并为进化心理学中的亲代投资及性别选择理论提供了佐证。娃娃脸效应的文化差异以及实践应用可能是这一领域未来研究的主要方向。     

大学生恋爱决策中的内隐与外显线索偏好的研究

本研究旨在探索大学生恋爱决策中的内隐和外显线索的偏好差异。研究一在访谈和问卷调查的基础上,筛选出大学生在恋爱决策中关注的十四条线索,并让38名男性和52名女性大学生对这些线索进行重要性评分,从而比较不同性别的被试在线索重要性上的差异,结果显示不同性别的大学生在品行、个人修养、性格、职业、经济条件、家庭背景和学历这些线索上有显著差异;研究二分别选取了男性和女性大学生最为关注的前八条线索,并通过眼动仪探索被试进行恋爱决策时的内隐线索排序,与通过自陈问卷获得的外显线索排序进行比较,旨在探索被试的内隐与外显线索的重要性排序差异。研究二采用恋爱6个月以上关系稳定的眼动被试群体。结果显示,对于不同性别的被试,其内隐与外显条件下在某些线索重要性方面的排序上存在显著差异;女性被试的平均注视时间排序和对线索重要性排序在某些线索上也存在显著差异,而不同性别的被试对某些线索上的平均瞳孔大小排序上也和内隐线索重要性的排序上存在显著差异。     

陌生人印象偏好的实验研究

以80名大学女生为被试,在关系自我理论的框架下,采用移情研究的双时段范式,以实验法考察了关系自我和重要他人对于陌生人印象偏好的影响。结果发现：在无提示的条件下,与重要他人相似的陌生人得到更多的印象偏好;在有提示的条件下,这种由相似性而产生的偏好会显著降低。证明了重要他人对陌生人印象偏好的影响,并讨论了关系自我在其中发挥的中介作用。     

青少年网络社交使用频率对网络成瘾的影响:家庭经济地位的调节作用

相关研究表明,由于青少年在网络社交中能够获得他人的认可与支持,网络社交对网络成瘾具有显著的影响。自我价值定向理论认为自我价值是人们行为的终极理由,其中他人的认可与接纳、家庭社会经济地位都是自我价值的重要支撑。当青少年生活在高社会经济地位环境中,其自我价值可能越高,网络社交使用频率对网络成瘾的影响可能会减弱。我们从全国7个省收集了1216份青少年自评的网络社交使用频率、网络成瘾倾向以及父母自评的社会经济地位等指标的数据。结果表明:家庭社会经济地位调节着网络社交使用频率与网络成瘾倾向的关系;进一步的分析表明,在高社会经济地位的家庭中,青少年的网络社交使用频率对网络成瘾倾向的影响不显著,而在低社会经济地位的家庭中,青少年的网络社交使用频率对网络成瘾倾向的影响极其显著。结果支持了自我价值定向理论。     

从恢复体验到地方依恋:环境偏好与居住时长的作用

探究源自环境的恢复体验(如,放松、平静等)对居住者地方依恋(包括地方依赖和地方认同两个维度)的预测作用,并分析其中的内在过程与情境条件。采用问卷研究法(N=410),结果发现:(1)恢复体验能显著正向预测个体地方依恋;(2)环境偏好在恢复体验与地方依恋之间起完全中介作用;(3)居住时长调节环境偏好与地方依恋(主要是地方认同)之间的关系。研究将有助于探寻环境心理学视角下的压力管理与城市管理协同路径。     

The Effect of Expected Value on Attraction Effect Preference Reversals

The attraction effect shows that adding a third alternative to a choice set can alter preference between the original two options. For over 30 years, this simple demonstration of context dependence has been taken as strong evidence against a class of parsimonious value‐maximising models that evaluate alternatives independently from one another. Significantly, however, in previous demonstrations of the attraction effect alternatives are approximately equally valuable, so there was little consequence to the decision maker irrespective of which alternative was selected. Here we vary the difference in expected value between alternatives and provide the first demonstration that, although extinguished with large differences, this theoretically important effect persists when choice between alternatives has a consequence. We use this result to clarify the implications of the attraction effect, arguing that although it robustly violates the assumptions of value‐maximising models, it does not eliminate the possibility that human decision making is optimal. © 2016 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.     

The Common Ratio Effect in Choice,Pricing, and Happiness Tasks

The Allais common ratio effect is one of the most robust violations of rational decision making under risk. In this paper, we conduct a novel test of the common ratio effect in which we elicit preferences for the common ratio choice alternatives in choice, pricing, and happiness rating tasks. We find large shifts in preference patterns across tasks, both within and between subjects. In particular, we find that both the consistency and distribution of responses differ systematically across tasks, with modal choices replicating the Allais preference pattern, modal happiness ratings exhibiting consistent risk aversion, and modal prices maximizing expected value. We discuss the predictions of various cognitive explanations of the common ratio effect in the context of our experiment. We find that a dual process framework provides the most complete account of our results. Surprisingly, we also find that although the Allais pattern was the modal behavior in the choice task, none of the 158 respondents in our experiment exhibited the Allais pattern simultaneously in choice, happiness, and pricing tasks. Our results constitute a new paradox for the leading theories of choice under risk. Copyright © 2017 John Wiley & Sons, Ltd.     

Methodology to select solutions for multiobjective optimization problems: Weighted stress function method

The weighted stress function method is proposed here as a new way of identifying the best solution from a set of nondominated solutions according to the decision maker's preferences, expressed in terms of weights. The method was tested using several benchmark problems from the literature, and the results obtained were compared with those of other methods, namely, the reference point evolutionary multiobjective optimization (EMO), the weighted Tchebycheff metric, and a goal programming method. The weighted stress function method can be seen to exhibit a more direct correspondence between the weights set by the decision maker and the final solutions obtained than the other methods tested.     

Response competition and stimulus preference in the treatment of automatically reinforced behavior: a comparison

Clinicians are particularly challenged by the development of interventions for behavior maintained by automatic reinforcement because reinforcers that maintain the responses often cannot be directly observed or manipulated. Researchers have conducted either preference assessments or competing items assessments when developing effective treatments for behavior maintained by automatic reinforcement. However, interventions based on these assessments have not been directly compared. The current study evaluated procedures to make such a comparison. High-competition items resulted in greater reductions in vocal stereotypy than did high-preference items for a preschool boy with autism.
