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.
