Verb frame frequency as a predictor of verb bias

There is considerable evidence showing that the human sentence processor is guided by lexical preferences in resolving syntactic ambiguities. Several types of preferences have been identified, including morphological, syntactic, and semantic ones. However, the literature fails to provide a uniform account of what lexical preferences are and how they should be measured. The present paper provides evidence for the view that lexical preferences are records of prior linguistic experience. We show that a type of lexial syntactic preference, viz., verb biases as measured by norming experiments, can be approximated by verb frame frequencies extracted from a large, balanced corpus using computational learning techniques.     

American base‐rate neglect: It is not the math,but the context

We investigate cross‐cultural disparities in focalism bias through two studies of probability estimation. Using 60 American and 60 Chinese participants, Experiment 1 yields the standard finding that Americans manifest greater focalism bias by tending to neglect background probability base‐rates and to rely more heavily on obtained samples in estimating true probabilities, whereas Chinese participants show little tendency to ignore base‐rates. In Experiment 2, the phrasing of the probability‐estimation task is changed to bring base‐rates into the focus of the problem statement, again using a sample of 60 Americans and 60 Chinese. This allows us to test whether cross‐cultural differences result from a tendency to focus on the sample, and ignore ‘context’ (i.e., the background base‐rates), rather than simply a discrepancy in mathematical facility between the two groups. The results show far less base‐rate neglect for Americans, but essentially no change for Chinese (who always use base‐rate information, regardless of how presented). This outcome argues against the explanation that Americans are poorer Bayesians simply because they are weaker mathematicians. Implications are discussed.     

高强迫症状个体对图片刺激的注意偏向

以往强迫症注意偏向研究呈现出不一致的结果。为探索研究结果的不一致性是否由于被试取样和刺激选择所导致,当前研究改用非临床强迫症状个体作为研究对象,采用图片作为刺激来引发被试的反应和脑电波的变化。研究采用2(高强迫症状组、低强迫症状组)×3(中性图片、一般威胁图片和强迫相关图片)的混合实验设计,因变量为反应时和相关的脑电成分,结果显示:高强迫症状组较低强迫症状组对强迫相关图片表现出了更大幅度的P2波幅的变化。从而可以推断出,高强迫症状个体对强迫相关图片表现出了明显的注意偏向,其成分为注意脱困,主要发生在早期自动化加工阶段。     

The dynamics of affect across the wake-sleep cycle: From waking mind-wandering to night-time dreaming

Affective experiences occur across the wake-sleep cycle—from active wakefulness to resting wakefulness (i.e., mind-wandering) to sleep (i.e., dreaming). Yet, we know little about the dynamics of affect across these states. We compared the affective ratings of waking, mind-wandering, and dream episodes. Results showed that mind-wandering was more positively valenced than dreaming, and that both mind-wandering and dreaming were more negatively valenced than active wakefulness. We also compared participants’ self-ratings of affect with external ratings of affect (i.e., analysis of affect in verbal reports). With self-ratings all episodes were predominated by positive affect. However, the affective valence of reports changed from positively valenced waking reports to affectively balanced mind-wandering reports to negatively valenced dream reports. These findings show that (1) the positivity bias characteristic to waking experiences decreases across the wake-sleep continuum, and (2) conclusions regarding affective experiences depend on whether self-ratings or verbal reports describing these experiences are analysed.     

攻击动机对特质愤怒与反应性攻击关系的中介作用：一项纵向研究

特质愤怒是影响反应性攻击的重要人格因素, 反应性攻击的提出是基于攻击动机, 但是特质愤怒影响反应性攻击的动机机制尚不清楚。本研究假设特质愤怒可以通过增强反应性攻击的特异性动机(即敌意性动机)以及反应性攻击与主动性攻击的共同性动机(即道德准许动机)来纵向预测反应性攻击。为了检验该假设, 对5个省市共1007名大学生的特质愤怒、敌意归因偏向(代表敌意性动机)和道德推脱(代表道德准许动机)、反应性攻击与主动性攻击进行了3次追踪调查。结果显示：(1)在控制性别后, 第一个时间点的特质愤怒可以通过第二个时间点的敌意归因偏向和道德推脱预测第三个时间点的反应性攻击; (2)敌意归因偏向只能纵向预测反应性攻击, 而不能跨时间预测主动性攻击; (3)道德推脱可以纵向预测反应性攻击和主动性攻击。这一结果支持了特质愤怒影响反应性攻击的动机模型, 发展了人格与攻击关系的理论与研究, 对于揭示反应性攻击形成的动机机制具有积极作用。     

Of unbiased beans and slanted stocks: Neutral stimuli reveal the fundamental relation between political ideology and exploratory behaviour

Fiagbenu et al. (2019, British Journal of Psychology) questioned the nature and extent of ideological differences in learning and behaviour documented by Shook and Fazio (2009, Journal of Experimental Social Psychology, 45, 995). We correct a mischaracterization in their depiction of Shook & Fazio’s research, and in doing so, we outline why the original findings represent domain-general ideological differences in attitude-formation processes, rather than simple differences in responses to physical threat. We also report new data that suggest a potential mechanism for the authors’ findings and further highlight the importance of novel, ideologically neutral stimuli when examining fundamental psychological differences between liberals and conservatives.     

What is a face worth? Facial attractiveness biases experience-based monetary decision-making

There is ample evidence that attractive individuals, across diverse domains, are judged more favourably. But most research has focused on single/one-shot decisions, where decision-makers receive no feedback following their decisions, and outcomes of their judgements are inconsequential to the self. Would attractive individuals still be judged favourably in experience-based decision-making where people make iterative decisions and receive consequential feedback (money gained/lost) following each decision? To investigate this question, participants viewed headshots of four financial partners presented side-by-side and repeatedly (over 50–100 trials) selected partners that would help maximize their profits. Following every partner-selection, participants received feedback about the net monetary gains/losses the partner had conferred. Unbeknownst to participants, two partners (one attractive, one unattractive) were equally advantageous (conferred net-gains overtime) and two partners (one attractive and one unattractive) were equally disadvantageous (conferred net-losses overtime). Even though attractive and unattractive partners were equally profitable and despite receiving feedback, participants selected attractive partners more throughout the task were quicker to reselect them even when they conferred losses and judged them as more helpful. Indeed, attractive-disadvantageous partners were preferred to the same extent (or more) as unattractive-advantageous partners. Importantly, the effect of attractiveness on decision-making was fully explained by the perceived trustworthiness of the financial partners.     

Does parochial cooperation exist in childhood and adolescence? A meta-analysis

Although previous meta-analytic evidence supports the existence of parochialism in cooperation among adults, the extent to which children and adolescents are more willing to incur a personal cost to benefit ingroups, compared to outgroups, is not yet clear. We provide the first meta-analysis on the existence and magnitude of parochialism in cooperation among pre-adults. Based on 20 experimental economics studies (k = 69, N = 5268, age = 3–19, 12 countries, published 2008–2019), a multilevel meta-analytic model revealed a small overall effect size indicating that children and adolescents were more cooperative towards ingroups (d = 0.22, 95% CI [0.07, 0.38]). A series of single-moderator analyses tested for the following conditions: participant age and sex; game type ([mini-]dictator game, prisoner's dilemma, public goods dilemma, trust game, ultimatum game); outcome interdependence; membership manipulation (between- vs. within-subjects); group type (natural vs. experimental); reward type (monetary vs. non-monetary); and country of the participant. Parochial cooperation did not vary with participants' age. Parochialism was larger in non-interdependent (dictator-type) compared to interdependent (bargaining and social dilemma) games. There were no moderating effects of group type, membership manipulation or reward type. To provide more data on how parochialism develops, primary studies should report age ranges more precisely and use more restricted age groups.     

Concurrent schedules: How responses per reinforcer affects estimates of sensitivity to reinforcement

Conventionally, when choice is measured under concurrent schedules, all responses are included. However, the class of all responses consists of 2 sub-classes which are discriminable by their properties: Reinforced responses always equal obtained reinforcers, while unreinforced responses are free to vary. As a result, the inclusion of reinforced responses in choice measures results in sensitivity values in generalized matching that are biased toward larger values, and this bias becomes extreme in some combinations of overall response and reinforcer rates. Different ways of varying concurrent-schedule values also affect estimated sensitivity and the linearity between choice based on all responses and reinforcer ratios. To avoid spurious results and comparisons, and as a matter of good practice, generalized-matching fits and measures should be done using only unreinforced responses.     

Effects of chronic exercise on attentional bias among individuals with methamphetamine use disorder

BackgroundIndividuals with substance use disorder show attentional bias toward drug-related cues, which may be associated with attentional control deficits. Although exercise improves attention in healthy people, whether individuals with substance use disorder also benefit is unknown. We explored the effects of chronic exercise on behavioral and neural correlates of attentional bias in men with methamphetamine use disorder.MethodsSixty-one such men were randomized to high- or moderate-intensity exercise or to a control group with little exercise for 12 weeks. The dot-probe task assessed attentional bias before and after exercise intervention, with event-related potentials recorded during the task to determine underlying neural mechanisms.ResultsAttentional bias scores and event-related potential amplitudes significantly decreased after high- or moderate-intensity chronic exercise, but not in controls.ConclusionsChronic exercise reduces attentional bias in individuals with methamphetamine use disorder by enhancing early identification of drug-related stimuli and diverting attention to reduce conflict processing.
