Positive affective tone and team performance: The moderating role of collective emotional skills

Research on affect as a group-level phenomenon has shown that over time, individual members within a group become highly similar in their affect (i.e., members experience and display similar emotions and moods), and often become similar enough that the aggregation of individuals’ affect can meaningfully represent the “affective tone” of the group. It is generally assumed that a more positive affective tone will lead to better team performance. We challenge the conclusion that positive affective tone is always good for team performance, suggesting that the relationship between positive affective tone and team performance is subject to moderating influences. Across two studies, we demonstrate that the self-reported collective emotional skills of team members play a crucial role in determining whether positive affective tone is beneficial or detrimental to team performance. Implications for theory and practice are discussed.     

绿色还是享乐?参与环保活动对消费行为的影响

以往对于环保问题的研究主要关注如何促进人们更多从事环保行为,较少有研究涉及参与环保行为后会产生怎样的影响,而且这方面的研究也没有一个一致的结论。通过3个实验发现当绿色消费和享乐消费是竞争关系时,对于认为环境价值观重要的个体来说,无论参与环保活动是出于内在动机还是外在动机都会增强消费者的环保自我担当,促进绿色消费,而对于认为环境价值观不重要的个体来说,只有参与环保活动是出于内在动机的时候才会增加消费者环保目标进展的感知,促进享乐消费,出于外在动机参与环保活动并不会促进享乐消费。     

急性疼痛与慢性疼痛对奖赏加工的影响及神经机制

疼痛和奖赏能够为个体提供不同的行为动机和主观价值体验,寻求奖赏和避免疼痛对于生存都很重要。疼痛可划分为急性疼痛和慢性疼痛,奖赏可区分为预期阶段的动机成分和体验阶段的享乐成分。奖赏对疼痛的抑制作用已经被广泛证实,但关于疼痛对奖赏的影响,目前的研究结果并不一致。因此需要进一步区分并探究急性疼痛与慢性疼痛对奖赏加工不同阶段的影响,分析两种疼痛对奖赏加工产生不一致影响的现象。这种现象出现的原因可能与急性疼痛向慢性疼痛转变过程中出现的奖赏加工能力缺陷有关。未来可以考虑从改善奖赏加工能力缺陷的角度进行检测和治疗,提前预防急性疼痛向慢性疼痛转变。     

Learning phonetic categories by tracking movements

We explore in this study how infants may derive phonetic categories from adult input that are highly variable. Neural networks in the form of self-organizing maps (SOMs; ) were used to simulate unsupervised learning of Mandarin tones. In Simulation 1, we trained the SOMs with syllable-sized continuous F(0) contours, produced by multiple speakers in connected speech, and with the corresponding velocity profiles (D1). No attempt was made to reduce the large amount of variability in the input or to add to the input any abstract features such as height and slope of the F(0) contours. In the testing phase, reasonably high categorization rate was achieved with F(0) profiles, but D1 profiles yielded almost perfect categorization of the four tones. Close inspection of the learned prototypical D1 profile clusters revealed that they had effectively eliminated surface variability and directly reflected articulatory movements toward the underlying targets of the four tones as proposed by . Additional simulations indicated that a further learning step was possible through which D1 prototypes with one-to-one correspondence to the tones were derived from the prototype clusters learned in Simulation 1. Implications of these findings for theories of language acquisition, speech perception and speech production are discussed.     

Stimulus control and compounding with ambient odor as a discriminative stimulus on a free-operant baseline

Previous experiments have demonstrated that the simultaneous presentation of independently established discriminative stimuli can control rates of operant responding substantially higher than the rates occasioned by the individual stimuli. This "additive summation" phenomenon has been shown with a variety of different reinforcers (e.g., food, water, shock avoidance, cocaine, and heroin). Discriminative stimuli previously used in such studies have been limited to the visual and auditory sensory modalities. The present experiment sought to (1) establish stimulus control on a free-operant baseline with an ambient olfactory discriminative stimulus, (2) compare olfactory control to that produced with an auditory discriminative stimulus, and (3) determine whether compounding independently established olfactory and auditory discriminative stimuli produces additive summation. Rats lever pressed for food on a variable-interval schedule in the presence of either a tone or an odor, with comparable control developed to each stimulus. In the absence of these stimuli responding was not reinforced. During stimulus compounding tests, the tone-plus-odor compound occasioned more than double the responses occasioned by either the tone or odor presented individually. Thus, the current study (1) established stimulus control with an ambient olfactory discriminative stimulus in a traditional free-operant setting and (2) extended the generality of stimulus-compounding effects by demonstrating additive summation when olfactory and auditory discriminative stimuli were presented simultaneously.     

Leadership and the contagion of affective phenomena: A systematic review and mini meta-analysis

We present a systematic review of literature examining leadership and the contagion of affective phenomena, namely emotion, mood, and affect. Specifically, an inductive thematic analysis approach was adopted to synthesize the findings from published studies. In addition, a mini meta-analysis was conducted to quantify reported effects. A rigorous search identified 25 studies that fulfilled the inclusion criteria for further review. Results highlighted important relationships between leadership and contagion aligned with six themes: Charismatic and transformational leadership are conducive to contagion of leader and follower positive affective phenomena; greater contagion effects exists when there is congruence between leader and follower affective states; contagion of leader and follower affective phenomena is directly linked to leader effectiveness and performance; and, individual susceptibility to the contagion of affective phenomena can moderate these relationships. These findings have salient implications for conceptualization and measurement across multiple lines of inquiry and within numerous domains of application.     

The impact of different product formats on inaction inertia

ABSTRACT

The inaction inertia effect describes situations in which a person rejects an opportunity after having forgone a relatively superior opportunity. This study explores whether product format (hedonic vs. utilitarian) affects the inaction inertia effect. The authors build on previous findings that show comparisons of utilitarian benefits are easier than hedonic benefits, and hedonic consumption (vs. utilitarian consumption) usually generates greater pleasure. The authors propose that people show higher inaction inertia after they have missed a superior utilitarian consumption opportunity than after they have missed a superior hedonic consumption opportunity. This prediction was tested and supported in three different experiments. Moreover, the authors found that differences in comparability between products, rather than the hedonic pleasure, explain differences in inaction inertia effects. These findings contribute to the inaction inertia literature and marketing practice.     

Mood as a Result of Temperament Profile: Predictions from the Regulative Theory of Temperament

The paper examines the relationship between three dimensions of mood and temperament traits according to the Regulative Theory of Temperament (RTT). The theory emphasises the role of temperament in meeting environmental requirements and implies that temperamental traits influence mood. The results showed that subjective level of energy was linked most strongly to activity (undertaking behaviours providing intense stimuli). It is questioned whether energy should be considered as a result or a cause of high activity. The best predictor of tense arousal and hedonic tone proved to be emotional reactivity. The former mood dimension was positively related to emotional reactivity, whereas the latter was negatively linked to this trait. The results are consistent with previous investigations on neuroticism and extraversion and widen the knowledge on temperamental predictors of mood by showing associations between briskness and all three mood dimensions. Moreover, the results showed that advantageous mood profile was associated with advantageous temperamental structure which corroborates the relevance of RTT.     

Examining the effects of variation in emotional tone of voice on spoken word recognition

Emotional tone of voice (ETV) is essential for optimal verbal communication. Research has found that the impact of variation in nonlinguistic features of speech on spoken word recognition differs according to a time course. In the current study, we investigated whether intratalker variation in ETV follows the same time course in two long-term repetition priming experiments. We found that intratalker variability in ETVs affected reaction times to spoken words only when processing was relatively slow and difficult, not when processing was relatively fast and easy. These results provide evidence for the use of both abstract and episodic lexical representations for processing within-talker variability in ETV, depending on the time course of spoken word recognition.
