Materialism lowers well‐being: The mediating role of the need for autonomy – correlational and experimental evidence

While there is evidence from the self‐determination perspective for the mediation of basic needs satisfaction in the materialism–well‐being link, no research to date has attempted to examine the relative contribution of the three needs to the mediating effect. Given that the predictive value of psychological needs on well‐being depends upon the match between the need and life domains, in two studies we investigate the differential mediating role of all three needs in the negative relationship between materialism and well‐being. In study 1, 231 adult participants self‐reported their materialistic attitudes, basic needs satisfaction and well‐being. In study 2 (N = 82 undergraduates), we experimentally activated materialistic thoughts and examined their effects on need satisfaction and state well‐being as compared to a neutral control condition. Study 1 furnished cross‐sectional evidence that materialism diminishes well‐being through lower satisfaction of the psychological need for autonomy only. Study 2 showed that experimental activation of materialism via short‐term exposure to pictorial consumer‐cues leads to lower satisfaction of the need for autonomy, which in turn produces higher negative affect among participants. The findings point towards the importance of considering the specific role of the psychological need for autonomy in the materialism–well‐being link.     

Attentional Capture by Emotional Stimuli: Manipulation of Emotional Valence by the Sample Pre‐rating Method

Eye movements directed at emotional and neutral pictures were investigated. Participants were instructed to fixate on a target and avoid looking at a non‐target. Results of trials consisting of emotional and neutral pictures were analyzed based on participants’ evaluations of the stimuli before the experiment. Results indicated that the number and duration of fixations were larger and longer for targets than for non‐targets. Further, the probability of first fixation was less for neutral targets than for emotional targets. This suggests that unpleasant pictures capture visual attention and that the attentional orienting is subject to automatic response. The possibility that top‐down processes of visual attention may be involved in attentional capture was also discussed.     

Stronger effects of self-generated than cue-induced expectations when verifying predictions in data graphs

Expectations can come in different forms when analyzing and presenting data. Prior studies have documented stronger effects (behavioral and electrophysiological) of self-generated predictions as compared to cues. While participants presumably cannot help but use their own predictions, they might sometimes ignore cues (of low validity). In two experiments we compared the impact of cues (verbal and visual) and self-generated predictions on the performance of participants checking their current prediction against a presented data graph (linear upward or downward trend). Different from prior studies, the setup allowed for within-experiment comparison of different cue formats and ensured that cues could not be ignored. Nevertheless we found that self-generated predictions had a stronger impact than cues. Verbal cues had a stronger effect than visual cues without verbalization. Responses to graphs with a linear upward trend were faster and were influenced more strongly by predictions, than the response to graphs with a downward trend.     

阈上和阈下不同情绪线索对返回抑制的影响

为检验返回抑制是否受线索生物学意义的调节, 分别在实验一和实验二中以阈上和阈下不同情绪效价(高兴、生气和中性)的面孔为外源性线索, 变化同时提示位置的多寡, 要求被试对靶子尽可能快而准地作探测反应。实验一发现, 三种线索情况下均出现返回抑制且效应量无显著差异; 实验二发现, 线索为中性面孔时出现返回抑制, 线索为高兴和生气面孔时未出现返回抑制。说明返回抑制受线索生物学意义的调节。阈下线索的生物学意义(情绪效价)能得到自动加工, 从而影响空间注意的转移和返回抑制机制的功用; 阈上线索的情绪效价被清晰感知时, 自上而下的注意控制机制使线索的生物学意义被忽略, 从而阻碍情绪效价功能的发挥。     

Underlying mechanisms of initial feelings of knowing in children

Past research has pointed to two contrasting mechanisms behind feeling‐of‐knowing judgments (FOKs). The trace‐based account proposes a direct internal monitor that detects the presence or non‐presence of a target item. The inferential account dictates that judgments are actually based on cues external to the memory trace, such as familiarity; FOKs could therefore be based on sometimes misleading information. Thus, while a direct mechanism will lead to good learning strategies (i.e. successful searches), an inferential process could potentially lead to less optimal strategies (i.e. search for unknown target information). The question posed in this research was: What processes underlie the judgments children make prior to fully retrieving a target item? We used a simplified version of Reder and Ritter's (1992 ) game show paradigm to investigate the accuracy (and mechanism) of children's initial FOKs. The experiment found that initial FOKs were largely driven by familiarity of the cues. These data have important implications for strategies children utilize in educational settings.     

认知方式与线索特征对前瞻记忆的影响

采用实验室研究范式,以汉语双字词为实验材料,探讨了场依存性认知方式、任务类型和线索特征对前瞻记忆的影响。研究结果表明：（1）场独立者的前瞻记忆成绩显著高于场依存者,而回溯记忆成绩没有明显差异;（2）基于事件的前瞻记忆成绩要明显好于基于时间的前瞻记忆成绩。（3）低熟悉性靶线索和与背景有区别的靶线索能促进前瞻记忆的完成,靶线索熟悉性和区别性之间存在非常明显的交互作用。     

态度改变的睡眠者效应研究概述

睡眠者效应是态度改变研究中一个有趣而反常的现象,是指在态度改变过程中,说服效果随着时间的推移不降低反而提高的一种现象。从霍夫兰1949年首次命名以来,对睡眠者效应研究的范围不断扩大,数量不断增多,研究逐渐深入。三种具有影响力的理论解释得以提出：线索分离假说、差别衰退假说和有用性-有效性假说。睡眠者效应产生的条件也被反复探究。当前对睡眠者效应研究的趋势是探索睡眠者效应的内在机制,并将其整合到统一的态度改变研究中去,同时展开睡眠者效应的应用研究。该文沿着历史的脉络,叙述了睡眠者效应研究中提出的理论,存在的争议和未来研究的趋势。     

Inducing lucid dreams by olfactory-cued reactivation of reality testing during early-morning sleep: A proof of concept

The reliable induction of lucid dreams is a challenge in lucid dream research. In a previous study by our research group we were able to induce in about 50% of the participants a lucid dream in a single sleep laboratory night by combining a wake-up-back-to-bed sleep protocol and a mnemonic technique. In the present study, we extended our previous procedure by additional presentation of an odor during sleep to reactivate memory traces about reality testing. In total 16 male participants spent a single night in the sleep lab whereas the procedure induced in two participants a lucid dream (12.5%). The induction rate stays below the success rate of our previous study and therefore odor-cueing seems not a promising technique for inducing lucid dreams. Beside the odor presentation, several other methodological changes have been made, which will be discussed and hopefully help further dream engineering to improve induction techniques.     

Individual differences in echocardiography: Visual object recognition ability predicts cue utilization

Echocardiographers are highly specialised, skilled practitioners who play a critical role in medical imaging diagnostics. Yet, little is known about the cognitive and perceptual attributes of experts within this domain. This study was designed to examine the role of individual differences in expertise. Specifically, the contribution of a domain general visual expertise and pattern recognition, or cue utilization. Data were collected from 42 echocardiographers and 43 naïve participants. All of the participants competed the Novel Object Memory Test (NOMT). When compared, the echocardiographers were more accurate than the naïve participants. The echocardiographers also completed an echocardiography edition of the Expert Intensive Skills Evaluation 2.0, to establish behavioral indicators of context-related cue utilization. Those with relatively higher cue utilization performed more accurately on the NOMT, controlling for exposure. These results suggest that a general perceptual ability contributes to echocardiography potential and a sensitivity to cue-based learning may contribute to expertise.     

注视线索对消费者的影响机制

心理学研究发现眼睛注视线索不仅能够引导社会性注意,还会影响个体对物品的感觉和知觉。注视线索对消费者的影响体现在认知和态度两方面：一方面,模特注视线索能够引导消费者注意,增强消费者对广告或产品的记忆;另一方面,模特注视线索会影响消费者对产品的喜欢程度和购买意愿,以及对服务人员的评价。未来可以从产品、消费者、消费情景及注视线索发起人等方面进一步探索注视线索对消费者心理和行为的影响。
