Dissociable Neural Mechanisms Underlie the Effects of Attention on Visual Appearance and Response Bias.

A prominent theoretical framework spanning philosophy, psychology, and neuroscience holds that selective attention penetrates early stages of perceptual processing to alter the subjective visual experience of behaviorally relevant stimuli. For example, searching for a red apple at the grocery store might make the relevant color appear brighter and more saturated compared with seeing the exact same red apple while searching for a yellow banana. In contrast, recent proposals argue that data supporting attention-related changes in appearance reflect decision- and motor-level response biases without concurrent changes in perceptual experience.

Stimulus visibility and uncertainty mediate the influence of attention on response bias and visual contrast appearance.

Although attention is known to improve the efficacy of sensory processing, the impact of attention on subjective visual appearance is still a matter of debate. Although recent studies suggest that attention can alter the appearance of stimulus contrast, others argue that these changes reflect response bias induced by attention cues. Here, we provide evidence that attention has effects on both appearance and response bias.

GPS sensor-based mobile learning for English: an exploratory study on self-efficacy, self-regulation and student achievement.

This study investigated the effects of self-efficacy and self-regulation on student achievement in a context-aware learning environment. Particularly, an innovative global positioning system (GPS) sensor-based mobile learning system was used to facilitate English learning of different plants on campus. A total of 41 university students participated in the study, divided into high and low groups of self-efficacy and self-regulation.

Multiscale cross-approximate entropy analysis as a measure of complexity among the aged and diabetic.

Complex fluctuations within physiological signals can be used to evaluate the health of the human body. This study recruited four groups of subjects: young healthy subjects (Group 1, n = 32), healthy upper middle-aged subjects (Group 2, n = 36), subjects with well-controlled type 2 diabetes (Group 3, n = 31), and subjects with poorly controlled type 2 diabetes (Group 4, n = 24). Data acquisition for each participant lasted 30 minutes.

The Arabidopsis hit1-1 mutant has a plasma membrane profile distinct from that of wild-type plants at optimal growing temperature.

High temperatures alter the physical properties of the plasma membrane and cause loss of function in the embedded proteins. Effective membrane and protein recycling through intracellular vesicular traffic is vital to maintain the structural and functional integrity of the plasma membrane under heat stress. However, in this regard, little experimental data is available.

Involvement of the Arabidopsis HIT1/AtVPS53 tethering protein homologue in the acclimation of the plasma membrane to heat stress.

Arabidopsis thaliana hit1-1 is a heat-intolerant mutant. The HIT1 gene encodes a protein that is homologous to yeast Vps53p, which is a subunit of the Golgi-associated retrograde protein (GARP) complex that is involved in retrograde membrane trafficking to the Golgi. To investigate the correlation between the cellular role of HIT1 and its protective function in heat tolerance in plants, it was verified that HIT1 was co-localized with AtVPS52 and AtVPS54, the other putative subunits of GARP, in the Golgi and post-Golgi compartments in Arabidopsis protoplasts.
