All role transitions are not experienced equally: Associations among self-change,emotional reactions,and self-concept clarity

Individuals experience numerous transitions across various roles during their lives. These role transitions can be disruptive to the way individuals view their identity, and thus their well-being; however, role transitions do not affect all individuals equally. Therefore, in the current work, we focused on two factors which may influence self-concept clarity and explain differential experiences following role transitions. We tested the relationship between the amount of self-change and positive emotions in reaction to a role transition predicting self-concept clarity, including both role entries (e.g. parenthood/new relationships, Studies 1–4) and role exits (e.g. divorce/job loss, Studies 3 and 4). Across several studies and all role transitions, we found that among individuals who experienced low levels of positive emotions after a role transition, greater self-change predicted reduced self-concept clarity. Among individuals who experienced higher levels of positive emotionality, this association did not emerge.     

When demand accelerates demand: Trailing the bandwagon

Consumers generally prefer scarce products, which has been related to their exclusiveness. Currently scarce products, however, are not necessarily exclusive, but could be scarce because many other consumers previously bought them. We propose that consumers also prefer scarce products in this situation, which an appeal to uniqueness cannot explain. Three experiments support our predictions and reveal that scarcity effects even occur when consumers only see traces of others' behavior through emptied shelf space. Furthermore, this bandwagon effect disappears when uniqueness is threatened due to others in close spatial distance.     

Global inhibition and midcourse corrections in speeded aiming

When some perceptual-motor relationships are reversed, participants might adopt a global inhibition strategy that replaces all normal movements with reversed movements. In two experiments, participants practiced moving a cursor from a start position to target locations. In a perceptual-motor reversal condition, in which horizontal but not vertical movements were reversed, participants were trained to move only to certain locations. Testing involved moving to all locations under the same reversal condition. Training on a subset of locations yielded partial transfer to untrained locations. These results support a global inhibition hypothesis modified to include both midcourse corrective movements and training specificity.     

A mental practice superiority effect: less retroactive interference and more transfer than physical practice

Two experiments explored the benefits to retention and transfer conferred by mental practice. During familiarization, participants typed 4-digit numbers and took an immediate typing test on both old and new numbers. Participants then typed old 4-digit numbers, either physically or mentally, with either a different response configuration or the opposite hand from that used during familiarization. On a delayed test, participants physically typed both old and new numbers with the same response configuration and hand used during familiarization. Mental practice led to less retroactive interference and more transfer than did physical practice, supporting the hypothesis that mental practice strengthens an abstract representation that does not involve specific effectors.

Evaluating different values of effort and reinforcement parameters under concurrent‐ and single‐operant arrangements

If particular parameters (e.g., reinforcer quality) are found to be preferred in a concurrent‐operant arrangement, then these should be incorporated into interventions for maintaining skills in individuals with intellectual disabilities. However, because results from a concurrent‐operant arrangement may not predict those of a single‐operant assessment, interventions with less preferred parameters may also be effective. The purpose of this study was to determine if preference for a particular parameter, determined via concurrent‐operant arrangements, predicted responding when two values of highly and less preferred parameters were manipulated in a single‐operant arrangement. Participants allocated responding to one parameter over another during concurrent‐operant assessments, indicating that certain parameters were highly preferred. However, contingent presentation of two values of less preferred parameters increased compliance to similar levels achieved with two highly preferred parameters in a single‐operant arrangement. These findings suggest that clinicians may have multiple options when selecting parameters for use during intervention.     

Focusing effects in predecisional information acquisition

Legrenzi et al. [Legrenzi, P., Girotto, V., & Johnson-Laird, P. N. (1993). Focusing in reasoning and decision making. Cognition, 49, 37-66] showed that when a single option is proposed for consideration the decision makers limit their information acquisition to this one option, failing to take into account potential alternatives. Unfortunately, the evidence supporting this focusing effect is weak and its determinants are largely unknown. In three experiments, we provided stronger support for the reality of the focusing effect and we identified two significant determinants of this phenomenon. The results show that both representational and value-related manipulations are able to reduce the effect. Results also suggest the need to distinguish between two different types of focusing: representational focusing and search-related focusing.
