The influences of tropical climate on imagined walking time

This study investigated the effects of a Tropical Climate (TC) on actual and imagined walking times. Participants had to execute and imagine walking 3 distances with or without a 10-kg weight in either a TC or an Air Conditioning (AC) condition. The motor imagery quality was evaluated by computing the isochrony index. The results revealed that movement times were shorter for imagined walking than for actual walking and increased with the distance of the paths in both cases. By contrast, the effect of the load increased actual walking times for the 10- and 15-meter distances without affecting imagined walking times. Importantly, the isochrony index was negatively affected by the increase in load and distance and the effects of distance were amplified in a TC. These findings showed that the environmental climate in which motor imagery arises can modulate the subject’s ability to build up the temporal characteristics of simulated actions.     

The Lausanne Trilogue Play paradigm: Breaking Discoveries in Family Process and Therapy

This article provides a brief history of key developments in the growth of the Lausanne Trilogue Play (LTP) paradigm that paved a foundation for new scholarship featured in the papers that follow. We outline core, foundational elements of the LTP work, highlighting the close interplay between clinical and research applications, the systems orientation in both regards, the dual attention to both top down (metamodel) and bottom up (microanalysis, in particular) frames, and the relevance of transitions from dyad to triad. Next, later developments in methodological refinement and expansion within the LTP’s country-of-origin are described, with closing commentary provided on the path-breaking contributions of several investigations that employed the LTP in five different countries, each illuminating previously under-studied family phenomena. The historical considerations spotlighted in this article, and the lessons learned from new empirical investigations the early work has inspired, are important to consider in tandem as the field begins expanding beyond the LTP’s original foundations and makes increasing use of the paradigm as a research instrument beyond clinical settings.     

Applying the SIDE model to brainwriting: The impact of intergroup comparison and anonymity on creative performance

According to the Social Identity model of Deindividuation Effects, intergroup comparison under anonymity accentuates social identity salience, potentially increasing motivation to work for one's group. The present experiment aimed to examine whether intergroup comparison and anonymity could boost creative performance in a brainwriting task. Sixty participants, randomly assigned to groups, wrote their ideas on sticky notes of the same (anonymity) or different color (individuation). To reinforce social identity salience, half the groups were told that their performance would be compared with other groups. As predicted, anonymity and intergroup comparison boosted both the number of nonredundant ideas produced by group members (fluency), and diversity of ideas pertaining to different categories (flexibility). By contrast, when social identity was not salient, anonymity led to an increase in the originality of ideas.     

Universal Principles of Human Communication: Preliminary Evidence From a Cross‐cultural Communication Game

The present study points to several potentially universal principles of human communication. Pairs of participants, sampled from culturally and linguistically distinct societies (Western and Japanese, N = 108: 16 Western–Western, 15 Japanese–Japanese and 23 Western–Japanese dyads), played a dyadic communication game in which they tried to communicate a range of experimenter‐specified items to a partner by drawing, but without speaking or using letters or numbers. This paradigm forced participants to create a novel communication system. A range of similar communication behaviors were observed among the within‐culture groups (Western–Western and Japanese–Japanese) and the across‐culture group (Western–Japanese): They (a) used iconic signs to bootstrap successful communication, (b) addressed breakdowns in communication using other‐initiated repairs, (c) simplified their communication behavior over repeated social interactions, and (d) aligned their communication behavior over repeated social interactions. While the across‐culture Western–Japanese dyads found the task more challenging, and cultural differences in communication behavior were observed, the same basic findings applied across all groups. Our findings, which rely on two distinct cultural and linguistic groups, offer preliminary evidence for several universal principles of human communication.     

Selflessness Meets Higher and More Stable Happiness: An Experience Sampling Study of the Joint Dynamics of Selflessness and Happiness

Previous studies have demonstrated the existence of a positive relationship between selflessness and happiness. However, none of these studies yet differentiated the between—and within—person levels of analysis. Moreover, the Selflessness/Selfcenteredness Happiness Model (SSHM) suggests that selflessness might stabilize happiness. In this experience sampling study, we explored the relationships between selflessness and happiness—baseline and stability—at both the within and betweenperson levels. During five consecutive days, participants responded seven times a day to short questions about happiness and selflessness. Our results showed that more selfless individuals were happier and that more selfless moments of an individual were also happier moments. Moreover, more selfless individuals were more stable from one day to the other. Finally, people becoming more selfless experienced more happiness stability at the following assessment moment and the next day. This study brings new evidence of the importance of selflessness for happiness.

The influence of alexithymia and music on the incidental memory for emotion words

Alexithymia is a multifaceted personality construct which encompasses difficulties in identifying and expressing feelings along with an externally oriented cognitive style. We investigated whether congruent vs. incongruent emotional musical priming (happy and angry music) during encoding would moderate the effects of alexithymia on recognition rates. We found that high alexithymia scorers recognized fewer joy and anger words than low scorers. Angry music decreased recognition rates in high alexithymia scorers compared to low alexithymia scorers. The congruency and incongruency effects between music and words depended on alexithymia level. The anger deficit in high alexithymia scorers and the possible support provided by happiness cues are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Subjective reports of stimulus,response, and decision times in speeded tasks: How accurate are decision time reports?

Four experiments examined how accurately participants can report the times of their own decisions. Within an auditory reaction time (RT) task, participants reported the time at which (a) the tone was presented, (b) they decided on the response, or (c) the response key was pressed. Decision time reports were checked for plausibility against the actual RTs, and we compared the effects of experimental manipulations on these two measures to see whether the reported decision times showed appropriate effects. In addition, we estimated the amount of error associated with individual decision time reports by checking how often participants’ decision time reports were implausibly early (i.e., before stimulus onset) or late (i.e., after response), and by using several quantitative models. Overall, the results suggest that decision time reports are not very accurate but they may be usable for some purposes.     

Superior implicit memory: a pilot study

In this pilot study, implicit memory was examined in participants selected according to their scores on the Wechsler Memory Scale-Revised. Implicit memory was explored using a word-stem completion test after 24 participants had processed texts to be remembered. Variations in priming were observed among 12 Normal and 12 Good memorizers (Verbal Memory scores >110) following presentation of target words in the context of a coherent text. One intriguing result emerged: the magnitude of the priming effect varied by group, greater among Good memorizers than Normal memorizers.     

Atypicality and the two fundamental dimensions: Applying the negativity effect on warmth to group perception

The person perception literature has shown that negative information on warmth influences impression formation more than other kinds of information. In the present paper, we argue for the usefulness of using the knowledge accumulated on the negativity effect on warmth when studying how members of a group who are disconfirming the group stereotype are perceived. We show that negative divergent information on warmth is perceived as more surprising because it appears to be more discrepant than positive divergent information on warmth or than competence information. We also show how stereotype holders protect their stereotype by rating the surprising incoherent information as atypical. Results are discussed in terms of the necessity to apply our knowledge of the two fundamental dimensions of social perception and their properties to typicality ratings and, beyond them, to stereotype change research.
