Alexithymia and risk preferences: Predicting risk behaviour across decision domains

Risk‐taking is a critical health factor as it plays a key role in several diseases and is related to a number of health risk factors. The aim of the present study is to investigate the role of alexithymia in predicting risk preferences across decision domains. One hundred and thirteen participants filled out an alexithymia scale (Toronto Alexithymia Scale—TAS‐20), impulsivity and venturesomeness measures (I7 scale), and—1 month later—the Cognitive Appraisal of Risky Events (CARE questionnaire). The hierarchical regression analyses showed that alexithymia positively predicted risk preferences in two domains: aggressive/illegal behaviour and irresponsible academic/work behaviour. The results also highlighted a significant association of the alexithymia facet, externally oriented thinking (EOT), with risky sexual activities. EOT also significantly predicted aggressive/illegal behaviour and irresponsible academic/work behaviour. The alexithymia facet, Difficulty Identifying Feelings, significantly predicted irresponsible academic/work behaviour. The results of the present study provide interesting insights into the connection between alexithymia and risk preferences across different decision domains. Implications for future studies and applied interventions are discussed.     

Randomization procedures in single‐case intervention research contexts: (Some of) “the rest of the story”

Following up on articles recently published in this journal, the present contribution tells (some of) “the rest of the story” about the value of randomization in single‐case intervention research investigations. Invoking principles of internal, statistical‐conclusion, and external validity, we begin by emphasizing the critical distinction between design randomization and analysis randomization, along with the necessary correspondence between the two. Four different types of single‐case design‐and‐analysis randomization are then discussed. The persistent negative influence of serially dependent single‐case outcome observations is highlighted, accompanied by examples of inappropriate applications of parametric and nonparametric tests that have appeared in the literature. We conclude by presenting valid applications of single‐case randomization procedures in various single‐case intervention contexts, with specific reference to a freely available Excel‐based software package that can be accessed to incorporate the present randomization schemes into a wide variety of single‐case intervention designs and analyses.     

Effects of negative incentive shifts in food reward on rats' consumption of concurrent ethanol solutions

Frustration stress, typically operationalized as the unexpected loss of reinforcement, has been shown to engender substance use. Abrupt reductions in reinforcer magnitude likely also function as frustration stressors. These negative incentive shifts were previously shown to produce tap‐ and sweetened‐water drinking in rats. The purpose of this study was to investigate whether these shifts in food reward would occasion oral ethanol self‐administration. Nine male Long‐Evans rats operated on a two‐component multiple fixed‐ratio schedule with signaled components producing either a large (4 pellets) or small (1pellet) reinforcer. Components were pseudorandomly arranged to present 4 transitions between past and upcoming reinforcer magnitudes: small‐to‐large, small‐to‐small, large‐to‐large, and large‐to‐small (negative incentive shift). Experiment 1 investigated the effects of negative incentive shifts on consumption of concurrent, freely available 10% sucrose, 10% sucrose plus 10% ethanol, and following sucrose fading, 10% ethanol. Experiment 2 entailed continuation of schedule contingencies with a dose manipulation of 4 ethanol concentrations (0, 5, 10, and 20%) to assess dose‐dependent differences in transition‐type control and consumption. A lever‐press extinction condition was then conducted with 10% ethanol availability. In this novel model of frustration stress, negative incentive shifts prompted ethanol self‐administration at each dose investigated, whereas the other transitions did not.     

Individual Goal Orientations,Team Empowerment,and Employee Creative Performance: A Case of Cross‐level Interactions

Intrigued by relationship between team motivational context and individual characteristics in the organizational reality, we developed and tested a cross‐level model to investigate the interactive effects of team empowerment and individual goal orientations on individual creative performance through the mediating mechanism of an individual's creative self‐efficacy. Using multi‐wave multi‐source data from 63 R&D teams in three IT companies, we found that (1) team empowerment, individual learning goal orientation, and individual performance orientation are all positively related to individual creative performance through mediation of creative self‐efficacy; (2) learning orientation and performance approach orientation could both supplement the effects of team empowerment on individual creative self‐efficacy. Our findings point to the importance of individual goal orientation in shaping the effects of team motivation climates and provide insights for both scholars and practitioners. The specific practical implications include but are not limited to (1) individuals with learning and performance approach orientations should be identified during hiring procedures given that they could still thrive in less empowered teams and maintain a relatively high level of creative self‐efficacy and creative outcomes; (2) managers should consider assigning employees who are more learning oriented to more empowering and open‐ended tasks in order to obtain better creative results.     

Reaching Wuthering Heights with Brave New Words: The Influence of Originality of Words on the Success of Outstanding Best‐Sellers

The judgment and ultimately the success of creative products should be determined by their properties. However, it has not been considered so far whether the same applies to books. Earlier research has found an inverted‐U relationship between originality of stimuli and their success. Linguistic originality as a text feature could influence the success of books as creative products in a natural experiment. The present historiometric study investigated whether originality predicts the popularity in a significant sample, the most best‐selling English books from 200 years. Originality was calculated based on word frequency using a commercial service. Popularity was assessed with a composite measure including indicators like number of sold copies. Regression analysis indicated originality had a direct linear effect on popularity, partially moderated by the time of first publishing. That is, while originality was generally beneficial for the success of a best‐seller, the same originality was more appreciated at a later point in time. This is the first quantitative study supporting the long‐held assumption that the evaluation of creative narratives is influenced by temporal context. The fact that some works like The Great Gatsby got more appreciation when they were rediscovered may reflect a general principle rather than mere exceptions.     

Simple discrimination in stingless bees (Melipona quadrifasciata): Probing for select‐ and reject‐stimulus control

Simple and conditional discrimination training may produce various types of controlling relations. Responses may be controlled primarily by the positive stimulus (select–control relation) or by the negative stimulus (reject–control relation; the subject excludes the negative stimulus and chooses the positive). Bees learn to respond in simple and conditional discriminations. However, no study has searched for reject–control responding in Melipona bees. We trained Melipona quadrifasciata on a simple discrimination task (S+ vs. S‐; e.g., blue vs. yellow) and then probed for stimulus control with two types of probe trials, S+ versus a new stimulus (Select–control probes) and S‐ versus a new stimulus (Reject–control probes). For Group Different, a new‐stimulus color (e.g., white) was used in one type of probe and another color (e.g., black) was used in the other type. For Group Same, a single new‐stimulus color was used in both types of probes. On Select probes, the bees always preferred S+ to the new stimulus. On Reject probes, results were mixed. Depending on the colors used in training and probing, bees responded to both stimuli, and even preferred the S‐. The data suggest no control by the negative function of the S‐ and support the select‐stimulus control hypothesis of responding.     

Taking Time to Incubate: The Moderating Role of ‘What You Do’ and ‘When You Do It’ on Creative Performance

We explore how the choices available to individuals planning multi‐task work can facilitate the incubation of ideas and enhance creative performance. Using opportunistic assimilation theory, we hypothesize that two considerations can determine the effectiveness of incubation and creative performance. First, we argue that having the discretion to switch tasks when needed, as well as the timing of this discretionary switch between tasks (i.e., earlier versus later in the work process on the main task) is important. Second, the scope of the intervening task (i.e., in the same knowledge domain as the main task versus in a different domain) can lead to more effective incubation and creativity. Results of a laboratory study indicate that participants who made a discretionary switch to an intervening task later in their work process on the main task benefited significantly more in terms of creative performance than those who chose to switch earlier in their work process or chose not to switch tasks. Additionally, participants who worked on an in‐domain intervening task exhibited significantly higher creativity on the main task than those who worked on an out‐of‐domain intervening task. Furthermore, focus of attention on the main task partially mediated these results.     

Open Workplace Climate and LGB Employees' Psychological Experiences: The Roles of Self‐Concealment and Self‐Acceptance

This study explores how an environmental factor (i.e., a perceived open climate) shapes lesbian, gay, and bisexual (LGB) employees' job satisfaction and job anxiety through the mediating role of self‐concealment. It also investigates the moderating role of self‐acceptance. Results from 315 LGB employees supported the conclusion that a perceived open climate for minority sexuality increased job satisfaction and decreased job anxiety. The open climate–job anxiety relationship was mediated by self‐concealment, and both stages of this mediation process were moderated by self‐acceptance. These findings offer useful insights for counselors and managers to help LGB individuals improve their workplace psychological experiences.     

The Role of Positive Psychology,Cultural, and Family Factors in Latina/o College Students' Vocational Outcome Expectations

Latina/o college students (N = 120) provided their perceptions of positive psychology, cultural, family, and vocational outcome expectations. Presence of meaning in life, hope, Anglo orientation, and Mexican orientation were significant predictors of subjective happiness. Implications for counselors are provided.     

Hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance

Hemispheric predominance has been well documented in the visual perception of alphabetic words. However, the hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance are far from clear. In the divided visual field paradigm, participants were required to judge the orthography, phonology, or semantics of Chinese characters, which were presented randomly in the left or right visual field. The results showed a right visual field/left hemispheric superiority in the phonological judgment task, but no hemispheric advantage in the orthographic or semantic task was found. In addition, reaction times in the right visual field for phonological and semantic tasks were significantly correlated with the reading test score. These results suggest that both hemispheres involved in the orthographic and semantic processing of Chinese characters, and that the left lateralized phonological processing is important for Chinese fluent reading.
