Sex differences and parallels in the development of externalizing behaviours in childhood: Boys’ and girls’ susceptibility to social preference among peers

This study examined whether being poorly preferred by peers may partially explain why boys with oppositional behaviour develop more conduct problems than girls. Children from the general Dutch population attending regular elementary schools (N = 759, 50.3% boys) were followed annually from age 7 to 10 years. Teachers-rated externalizing behaviour and peer-nominated social preference was assessed across four waves. Autoregressive cross-lagged models indicated that oppositionality predicted increases in conduct problems. Above and beyond this direct link, oppositionality predicted low social preference in subsequent years, which in turn predicted an increase in conduct problems. In this latter pathway, sex differences were found. That is, oppositional boys were as likely as oppositional girls to show an increase in low social preference one year later. However, boys who had low social preference scores showed stronger increases in conduct problems one year later, compared to girls who had low social preference scores. Hence, developmental models of externalizing behaviour should consider the possible sex-differential impact of troublesome peer-relationships to understand the development of milder to more severe externalizing behaviours.     

注意分散对类比推理内隐加工的影响

通过两个实验分别考察在类比推理的检索阶段和评价阶段的注意分散对类比推理内隐加工的影响。实验一以83名大学生为被试,采用喜好判断范式探讨检索阶段注意分散对类比推理过程中直觉加工效应和逻辑加工效应的不同影响。实验二以80名大学生为被试,探讨评价阶段注意分散对类比推理过程中直觉加工效应和逻辑加工效应的不同影响。结果显示:检索阶段的注意分散对类比推理的内隐加工的影响不显著,评价阶段的注意分散对类比推理的内隐加工和外显加工均有显著影响。     

The loss‐bet paradox: Actuaries,accountants, and other numerate people rate numerically inferior gambles as superior

Psychologists have convincingly demonstrated that preferences are not always stable and, instead, are often “constructed” based on information available in the judgment or decision context. In 4 studies with experts (accountants and actuaries in Studies 1 and 2, respectively) and a diverse lay population (Studies 3 and 4), the evidence was consistent with the highly numerate being more likely than the less numerate to construct their preferences by rating a numerically inferior bet as superior (i.e., the bets effect). Thus, the effect generalizes beyond a college student sample, and preference construction differs by numeracy. Contrary to prior thinking about preference construction, however, high expertise and high ability (rather than low) consistently related to the paradoxical phenomenon. Results across studies including Study 3's experimental modifications of the task supported the hypothesized number comparison process (and not a lack of expertise with monetary outcomes and probabilities or numeracy‐related differences in attention to numbers) as the effect's underlying cause. The bets effect was not attenuated by Study 4's instructions to think about what would be purchased with bet winnings. Task results combined with free‐response coding supported the notion that highly numerate participants have a systematic and persistent inclination for doing simple and complex number operations that drive their judgments (even after controlling for nonnumeric intelligence). Implications for 3 types of dual‐process theories are discussed. The results were inconsistent with default‐interventionist theories, consistent or unclear with respect to fuzzy trace theory, and consistent with interactive theories.     

音乐的神经美学：从审美反应到神经基础

近年来, 随着音乐的神经科学与神经美学的发展, 逐渐形成一个新的研究领域, 即音乐的神经美学。这一研究领域关注音乐审美的心理过程和神经机制, 将注意力集中于音乐审美活动中的感知、认知和情感解释。音乐审美加工引起了相应的审美反应, 其中有三种音乐审美反应得到研究者更多的关注, 即音乐审美情绪、判断与偏好。研究者围绕这三种反应, 对音乐审美反应的知觉、认知、情绪加工和影响因素以及其神经机制展开研究。这些研究为我们理解音乐和美学的行为与神经机制提供了经验性证据。     

Further examination of video‐based preference assessments without contingent access

The first purpose of this study was to attempt to replicate previous findings that video‐based preference assessments without access to selected stimuli may accurately predict relative reinforcing efficacy of stimuli. To do this, we conducted a concurrent operant reinforcer assessment in which we evaluated the relative reinforcing value of highly preferred and less preferred items identified in a video‐based preference assessment. The second purpose of this study was to begin to evaluate the potential behavioral mechanisms responsible for the validity of this assessment. To conduct this analysis, we evaluated the relative reinforcing value of those same stimuli depicted in video format and then compared results to results obtained during the reinforcer assessment for tangible stimuli. For all five participants, stimuli identified as highly preferred functioned as reinforcers, and four of five participants, responding during the reinforcer assessment was similar in the presence of tangible stimuli and videos depicting those stimuli.     

Relative preferences for edible and leisure stimuli in children with autism

Prior researchers have reported a tendency for individuals with developmental disabilities to select edible items more often than leisure items when those items are presented together in stimulus preference assessments. However, children with autism spectrum disorders (ASD), with whom many behavior analysts currently practice, are underrepresented in this body of literature. We conducted a replication of prior research with 26 children with ASD. Results indicated that edible items were more likely than leisure items to rank highly in our preference assessments, in concurrence with prior research. However, leisure items were also selected more often overall than in prior research, and significant individual variation was observed. These results suggest that preference assessments containing both edible and leisure stimuli can yield useful information for behavior analysts providing services to children with ASD, and the degree of preference for edible items noted in prior work may not be reflected in this contemporary population.     

Assessing preference for types of social interaction

To date, few researchers have evaluated methods for assessing preference for social interactions. Due to concerns that commonly used stimulus preference assessment methods may be inappropriate, or at least cumbersome, for the assessment of social reinforcers, we developed and evaluated a new method of assessing preference for social interactions. A social interaction preference assessment (SIPA) and a concurrent operant reinforcer assessment were conducted with five participants diagnosed with autism spectrum disorder. A differentially preferred and reinforcing social interaction was identified for all five participants. The SIPA procedures, results, and the implications of these results are discussed.     

A closer look at the size of the gaze-liking effect: a preregistered replication

This study is a direct replication of gaze-liking effect using the same design, stimuli and procedure. The gaze-liking effect describes the tendency for people to rate objects as more likeable when they have recently seen a person repeatedly gaze toward rather than away from the object. However, as subsequent studies show considerable variability in the size of this effect, we sampled a larger number of participants (N?=?98) than the original study (N?=?24) to gain a more precise estimate of the gaze-liking effect size. Our results indicate a much smaller standardised effect size (d_z?=?0.02) than that of the original study (d_z?=?0.94). Our smaller effect size was not due to general insensitivity to eye-gaze effects because the same sample showed a clear (d_z?=?1.09) gaze-cuing effect – faster reaction times when eyes looked toward vs away from target objects. We discuss the implications of our findings for future studies wishing to study the gaze-liking effect.     

质量还是价格?折衷产品缺货情境下的消费者选择

基于情境效应和决策冲突理论, 通过三个实验探讨折衷产品选项的不可得如何影响消费者对余下可得产品的偏好。研究结果表明, 折衷商品不可得对余下商品的吸引力呈现非对称性的影响。以质量和价格产品属性的购买情境为例, 中等价格中等质量商品的不可得将显著提升低价格商品的吸引力(实验1), 其原因在于折衷方案不可得显著提高了消费者的决策冲突, 高水平的决策冲突导致决策者偏好具有确定性优势的选项, 规避优势存在模糊性的选项。随着质量属性模糊性的降低(提供专家评价, 实验2; 消费者专业知识较强, 实验3)或提高(质量存在波动范围, 实验2), 折衷商品不可得效应相应减弱或加强。
