Quantitating skill acquisition with optical ultrasound simulation.

Objective: To investigate and compare the effect of simulator training on quantitative scores for ultrasound-related skills for trainees with novice level ultrasound experience and expert ultrasound operators.

Methods: Three novice (comprising of 11, 32, 23 participants) and one expert (10 participants) subgroups undertook an ultrasound simulation training session. Pre- and post-training test scores were collected for each subgroup.

So much to do and so little time. Effort and perceived temporal distance.

In a series of five experiments, we showed that the perception of temporal distance to a future event is shaped by the effort one must invest to realize the event. Studies 1a and 1b showed that when actors are faced with realizing an event by a certain deadline, more effortful events are perceived as closer in time, regardless of the objective temporal distance to the deadline. This negative relationship was reversed, however, when deadlines were absent (Study 2).

Stereotypes help people connect with others in the community: a situated functional analysis of the stereotype consistency bias in communication.

Communicators tend to share more stereotype-consistent than stereotype-inconsistent information. The authors propose and test a situated functional model of this stereotype consistency bias: stereotype-consistent and inconsistent information differentially serve 2 central functions of communication--sharing information and regulating relationships; depending on the communication context, information seen to serve these different functions better is more likely communicated. Results showed that stereotype-consistent information is perceived as more socially connective but less informative than inconsistent information, and when the stereotype is perceived to be highly shared in the community, more stereotype-consistent than inconsistent information is communicated due to its greater social connectivity function.
