In two experiments listeners assessed how sounds represented data, as might be used in sonification. In Experiment 1, 209 undergraduates used magnitude estimation to define the relationship between three sound attributes (frequency, tempo, modulation index) and 10 data dimensions (size, temperature, pressure, velocity, number of dollars, urgency, proximity, attractiveness, danger, mass). Polarities and slopes (i.e. power function exponents) are reported and compared to predictions from the literature. In Experiment 2, 226 new participants demonstrated polarities and slopes are stable across a direct replication. Results show that listener expectations depend on both sound and data dimensions in use. While there are some unanimous expectations across listeners, there are also differences due to different mental models formed by participants, which may relate to listening experience.

Behavioral inhibition (BI) is a temperament associated with heightened vigilance and fear of novelty in early childhood, and social reticence and increased risk for anxiety problems later in development. However, not all behaviorally inhibited children develop signs of anxiety. One mechanism that might contribute to the variability in developmental trajectories is the recruitment of cognitive‐control resources. The current study measured N2 activation, an ERP (event‐related potential) associated with cognitive control, and modeled source‐space activation (LORETA; Low Resolution Brain Electromagnetic Tomography) at 7 years of age while children performed a go/no‐go task. Activation was estimated for the entire cortex and then exported for four regions of interest: ventromedial prefrontal cortex (VMPFC), ventrolateral prefrontal cortex (VLPFC), dorsal anterior cingulate cortex (dorsal ACC), and dorsal lateral prefrontal cortex (DLPFC). BI was measured in early childhood (ages 2 and 3 years). Anxiety problems and social reticence were measured at 7 years of age to ascertain stability of temperamental style. Results revealed that BI was associated with increased performance accuracy, longer reaction times, greater (more negative) N2 activation, and higher estimated dorsal ACC and DLPFC activation. Furthermore, early BI was only associated with social reticence at age 7 at higher (more negative) levels of N2 activation or higher estimated dorsal ACC or DLPFC activation. Results are discussed in the context of overcontrolled behavior contributing to social reticence and signs of anxiety in middle childhood.  相似文献

Popular stereotypes suggest that generational differences among workers present challenges for workplace managers. However, existing empirical research provides mixed evidence for generational differences in important values and attitudes. The current study extends generational effects research by examining differences in actual workplace behaviors. Drawing from commonly held generational stereotypes, the authors hypothesized that Baby Boomers would exhibit (Hypothesis 1) fewer job mobility behaviors and (Hypothesis 2) more instances of compliance‐related behaviors in comparison with both GenXers and Millennials, while (Hypothesis 3) GenXers would be less likely to work overtime in comparison with Baby Boomers and Millennials. A sample of 8,040 applicants at two organizations was used to test these predictions. Results provided support for Hypothesis 1 and Hypothesis 3 and partial support for Hypothesis 2, but the effect sizes for these relationships were small. It appears the effects of generational membership on workplace behavior are not as strong as suggested by commonly held stereotypes. Implications for future research and practice are discussed.  相似文献

Animals readily acquire positive odor-taste hedonic associations, but evidence for this in humans remains weak and was explored further. Retronasal pairing of odors with sucrose or salty stimuli (Experiment 1) increased the rated sweetness of sucrose-paired odors without altering liking, although changes in odor pleasantness correlated with sucrose liking. Experience of odors with sucrose or quinine by sweet likers (Experiment 2) found increased pleasantness and sweetness for sucrose-paired odors, whereas quinine-paired odors became less liked and more bitter. Odor-sucrose pairings in sweet likers and dislikers (Experiment 3) found increased sweetness in both groups but increased odor liking only in likers. These data suggest that evaluative and sensory learning are dissociable and that evaluative changes are sensitive to individual differences in sweet liking.  相似文献
