There's a time and a face: The time course of composite face processing.

Faces are considered a special class of holistically-processed object. The composite face task is a widely-used tool to infer holistic processing. In this task, recognition of 1 half of a composite face is shown to be hampered by interference from the other half of the face. Although this effect has been documented numerous times, when used in different paradigms, composite faces do not always exhibit effects consistent with holistic processing. The present study explored the cause of these discrepant findings by combining a composite face task with a signal-to-respond paradigm. The amount of time to make a face recognition decision was manipulated by introducing a response signal, and the resulting changes in accuracy were mapped over the time course of processing, which was then used to fit a speed-accuracy trade-off model. We found that holistic processing emerges late in the time course after approximately 400 ms processing time for easy-to-discriminate faces and after approximately 1000 ms for difficult-to-discriminate faces.

General and specific graphic health warning labels reduce willingness to consume sugar-sweetened beverages.

Sugar-sweetened beverage (SSB) consumption is associated with obesity and other severe negative health consequences. The present study examined the effectiveness of two types of health warning labels (HWLs) in modulating dietary choices for SSBs: specific HWLs, presenting health consequences associated with consuming SSBs, and general HWLs, presenting health consequences of an unhealthy diet and obesity. While electroencephalography (EEG) was recorded, 63 participants completed a computer-based task in which they were first randomly allocated to view either SBB-specific, general, or non-warning control HWLs. They then viewed images of a range of SSB products, varying on perceived healthiness and tastiness, and rated their willingness to consume (WTC) each one. Linear mixed-effect model analyses revealed that general and specific HWLs both decreased WTC SSBs perceived as tasty, compared to the control condition. For general HWLs, this effect was reduced for SSBs perceived to be healthy, suggesting that specific HWLs may be more effective at reducing SSB consumption. The EEG data showed that SSBs considered unhealthy elicited greater N1 amplitudes, and tasty SSBs elicited greater late positive potential (LPP) amplitudes, possibly reflecting attentional allocation and craving responses, respectively. However, no strong differences between HWL types were found. Taken together, the results suggest that graphic HWLs, both general and specific, have the potential to reduce SSB consumption, but they do not strongly modulate craving-related neural responses to SSBs.

Tratamiento de la disebacea y la rosacea con sulfacetamida / Treatment of disebacea y of rosacea with sulfacetamide

La sulfacetamida sódica se nos presenta como una vieja alternativa para un problema actual, de consulta frecuente, como es el eritema centro facial observado en la dermatitis seborreica (disebácea) que muchas veces después de controlar la descamación persiste. Se realizó un estudio prospectivo al azar utilizando sulfacetamida sódica en solución oftálmica al 15 por ciento aplicada en forma tópica, dos veces al día en áreas de eritema. Se controlaron los pacientes por 3 meses. Se obtuvo curación en los casos de dermatitis seborreica en 88 por ciento. En la rosácea se observó curación en un paciente y mejoría en el resto. Sugerimos que la sulfacetamida sódica es una alternativa eficaz y económica para el tratado de la disebácea, no así para la rosácea
