Do dispositional attributions regarding peer endorsers influence product evaluations?

The effect of a peer endorsement advertisement on research participants' attitudes toward the advertised product was examined. An advertisement for a Seiko watch and a questionnaire were administered to participants. The degree of dispositional attributions regarding the endorser's motivation and participants' subsequent attitudes associated with the Seiko watch were measured. In addition, other factors that might affect product evaluation were measured. Whether product evaluation could be accounted for by correspondence bias was investigated. The results showed that the degree of dispositional attributions correlated with product evaluations. There was no correspondence bias. Possible causes for the lack of correspondence bias are discussed and a model suggesting factors accounting for participants' product evaluations is presented.     

Differentiating between memory and interpretation biases in socially anxious and nonanxious individuals

Although individual cognitive biases toward threat in social anxiety are well established, few studies have examined the manner in which cognitive biases work in conjunction. In the present study, socially anxious ( n = 54 ) and nonanxious ( n = 58 ) individuals read 10 passages consisting of positive social or evaluative, negative social or evaluative, and neutral content and completed two cognitive tasks assessing memory of factual details and interpretation immediately and after 48 h. Socially anxious and nonanxious individuals did not differ in their memory for details presented in the passages. However, they made less positive and more negative interpretations of details included in the passages, particularly in positive passages that were self-relevant and particularly in positive passages after the delay. After including depression, state anxiety, and trait anxiety as covariates, biased interpretation of positive passages after the time delay remained significant, but biased interpretation of the self-relevant, positive passages did not. It is concluded that socially anxious individuals are characterized by accurate memory of threatening, factual material, but that they impose a biased interpretation upon that material, especially after some time has passed.     

Preattentive bias for snake words in snake phobia?

Stroop interference and skin conductance responses (SCRs) for words related to snakes, spiders, flowers, and mushrooms were studied in a group of women (n=40) with snake phobia who were randomised to a stress or no-stress condition. The 21 low-stress snake phobics showed Stroop interference for unmasked (but not for masked) snake words, compared with 21 age- and sex-matched controls. Stroop interference was not significantly different between high-stress and low-stress snake phobics. No support for stronger SCRs for masked snake words was found in snake phobics in a lexical decision task with masked presentations of the same words. The lack of a masked Stroop interference in snake phobics suggests a possible difference in cognitive-emotional mechanisms underlying specific phobia vs. other anxiety disorders that deserves further investigation.     

Sensitivity to relative reinforcer rate in concurrent schedules: independence from relative and absolute reinforcer duration

Twelve pigeons responded on two keys under concurrent variable-interval (VI) schedules. Over several series of conditions, relative and absolute magnitudes of reinforcement were varied. Within each series, relative rate of reinforcement was varied and sensitivity of behavior ratios to reinforcer-rate ratios was assessed. When responding at both alternatives was maintained by equal-sized small reinforcers, sensitivity to variation in reinforcer-rate ratios was the same as when large reinforcers were used. This result was observed when the overall rate of reinforcement was constant over conditions, and also in another series of concurrent schedules in which one schedule was kept constant at VI ached 120 s. Similarly, reinforcer magnitude did not affect the rate at which response allocation approached asymptote within a condition. When reinforcer magnitudes differred between the two responses and reinforcer-rate ratios were varied, sensitivity of behavior allocation was unaffected although response bias favored the schedule that arranged the larger reinforcers. Analysis of absolute response rates ratio sensitivity to reinforcement occurrred on the two keys showed that this invariance of response despite changes in reinforcement interaction that were observed in absolute response rates on the constant VI 120-s schedule. Response rate on the constant VI 120-s schedule was inversely related to reinforcer rate on the varied key and the strength of this relation depended on the relative magnitude of reinforcers arranged on varied key. Independence of sensitivity to reinforcer-rate ratios from relative and absolute reinforcer magnitude is consistent with the relativity and independence assumtions of the matching law.     

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.
