The effect of temporal constraints on the value of money and other commodities

The value of hypothetical rewards of various delays and durations, consisting of money or other commodities, such as automobile use and vacations, was measured by the psychophysical up-down staircase method using an amount of unrestricted immediate money as the titrated variable. A model of temporal discounting based on implied constraints on anticipated consumption rate described the data. Further explicit constraints on consumption produced predictable deviations from the model. The concept that consumption is normally constrained together with time discounting may also explain the interaction between amount and delay of monetary reward in determining value and may provide the basis for a theory of addiction based on learning to increase consumption rate.     

These two are different. Yes,they’re the same: Choice blindness for facial identity

We examined the manipulability of face identity judgements by combining a sorting task for unfamiliar faces with a standard test of choice blindness. In Experiment 1, 50 participants completed a sorting task and then justified grouping specific pairs of photos together or apart. On manipulated trials, the presented pairings were different from those the participants had actually produced. Detection rates for these identity manipulations were strikingly low (∼21%). Moreover, participants readily provided justifications for identity decisions that they had not made, typically referring to specific facial features. Experiment 2 was conducted along similar lines and confirmed that lower task difficulty and higher confidence in one’s face identity judgements increase detection rates. We conclude that observers can easily be led to believe that they made identity judgements they did not make. As well as underscoring the fragility of unfamiliar face matching, our findings have implications for identity judgements in legal settings.     

Leading in times of crisis: How perceived COVID-19-related work intensification links to daily e-mail demands and leader outcomes

The COVID-19 crisis brought numerous challenges to work life. One of the most notable may be the acceleration of digital transformation, accompanied by an intensification of e-mail usage and related demands such as high e-mail workload. While research quickly started to examine the implications of these changes for employees, another important group of stakeholders has been overlooked: leaders. We focus on leaders during the COVID-19 crisis and examine how COVID-19-related work intensification links to leaders' e-mail overload appraisal and finally exhaustion and transformational leadership, a leader behaviour especially needed in times of crisis. In a 5-day diary study in September 2020, 84 leaders responded to daily surveys on 343 days. Results of multilevel analysis showed that perceived COVID-19-related work intensification was positively linked to worktime spent dealing with e-mail and appraised e-mail overload. E-mail overload appraisal was positively related to leaders' exhaustion, but unrelated to their transformational behaviour. Day-specific time spent dealing with e-mail, however, was negatively related to transformational leadership. E-mail overload appraisal mediated the relationship between COVID-19-related work intensification and exhaustion. Turning the focus on leaders during the COVID-19 crisis, our study has important implications for the design of work of leaders in times of crisis and beyond.     

Active involvement,not illusory control,increases risk taking in a gambling game

The research considers the influence of choice (the possibility for the player to choose a gamble or another) and involvement (the physical interaction with the gambling device) on risk taking in gambling games and whether this influence is mediated by illusory control over the outcome of the gamble. Results of a laboratory experiment (n = 100) show that (a) although choice does increase illusory control, this influence does not translate in increased risk taking, and (b) whilst involvement does increase risk taking, this effect is not mediated by illusory control. These results are discussed in relation to problem gambling, beliefs in the deployability of personal luck, and arousal approaches to risk taking.     

Social cognitive model of adjustment to engineering majors: Longitudinal test across gender and race/ethnicity

We conducted a longitudinal test of a social cognitive model of academic adjustment in a sample of 732 engineering students. The model, designed to explain students' satisfaction with and intentions to persist in their majors, integrated features of social cognitive career theory's (SCCT) segmental models of satisfaction, interest, choice, and performance (Lent & Brown, 2006; Lent, Brown, & Hackett, 1994). Students completed measures of academic support, self-efficacy, outcome expectations, interests, satisfaction, positive affect, and intended persistence at three time points (at the end of their second, third, and fourth semesters in engineering). A bidirectional version of the model offered good fit to the data, both in the larger sample and across gender and racial/ethnic groups. Self-efficacy was the most reliable direct predictor of academic satisfaction and intended persistence across the third and fourth semesters, though other social cognitive variables also contributed, either directly or indirectly, to predictions at one time point or the other. We consider implications of the findings for further research and practice on academic adjustment and persistence in STEM fields.     

记忆提取的决定因素:线索负荷、编码-提取匹配和辨别

"哪些因素决定提取效果"是记忆研究的主要问题之一。线索负荷假说认为与提取线索相关联的项目数量决定了提取效果,编码-提取匹配假说则强调编码与提取阶段的匹配程度决定提取成绩。这两者在记忆研究的不同时期均受到研究者的关注。在整合以往研究的基础上,有研究者提出了记忆是一个辨别过程的新观点,认为真正对回忆成绩起决定作用的是线索在多大程度上与某一目标项目匹配并能排除其他可能的备选项目。该观点对深入探索"哪些因素决定提取效果"这一问题提供了新的视角。在未来的研究中,研究者应正确看待辨别过程观点与编码-提取匹配观点的关系,同时可以借助新的技术手段从多个层面对这一新观点进行检验,并进一步丰富和完善该理论解释。     

Managing information overload in virtual teams: Effects of a structured online team adaptation on cognition and performance

Information overload (IO) indicates the exchange of too much low-quality information in virtual teams. When being overloaded with information, teams need to adapt and to change communication behaviour. This study introduces and tests a structured online team adaptation (STROTA) procedure that enables virtual teams to reduce IO by improving their team mental model quality. STROTA, built from team adaptation models, is a moderated intervention consisting of three stages: (1) individual situation awareness, (2) team situation awareness, and (3) plan formulation. STROTA was tested in the context of an experimental problem-solving task. Participants (N = 363) worked in virtual teams of three and were randomly assigned to one of four experimental conditions: no STROTA, incomplete STROTA (step 1, steps 1–2), and complete STROTA (steps 1–2–3). We found teams that followed a complete STROTA procedure experienced lessened IO over time. Teams with complete STROTA showed the largest development of TMM immediately after STROTA. Finally, multilevel mediation analyses showed that TMM are mediators that explain the influence of STROTA on IO.     

Help or hinder? When recommendation signage expands consideration sets and heightens decision difficulty

This research examines whether recommendation signage helps or hinders the consumer when faced with choosing from large product assortments. In spite of frequent usage and retailer intuition suggesting that providing recommendation signs (e.g., “Best Seller,” “Award Winner”) should help consumers in the choice process, we propose that signs can hinder choice for consumers with more developed preferences by adding to the complexity and difficulty of the decision process. In three experiments using horizontally differentiated products in multiple categories, we provide evidence that recommendation signs create preference conflict for consumers with more developed preferences, leading these consumers to form larger consideration sets and ultimately experience more difficulty from the decision-making process. In addition, we show that these effects are mitigated for consumers with less developed preferences and when the choice is from a small assortment. The results suggest that recommendation signage may not be an effective tool for aiding choice from large assortments; instead signage can exacerbate the difficulties associated with having too many choices, with implications on purchase quantity.
