The perceived contrast of a central stimulus can be decreased (surround suppression) or increased (surround facilitation) by the presence of surround stimuli. In this report we examined center-surround interactions in foveal and peripheral vision using contrast-matching tasks. We found that: (1) surround suppression became markedly stronger as the center-surround stimulus was moved toward the p...

Organizations have the potential to achieve advantage through communities of practice (COPs) initiatives. However, establishing and sustaining COPs is a challenging task. Facilitation is needed to help COPs overcome difficulties throughout their life stages. Facilitators take on leadership roles within these virtual communities, yet little is known about the challenges related to their roles. T...

Repeated words are often reduced in prosodic prominence, but the underlying mechanisms remain unclear. The present study contrasted two theories: does prosodic reduction reflect the choice of a particular linguistic form, or does ease of retrieval within the language production system lead to facilitated, less prominent productions? One test of facilitation-based theories is suggested by findin...

institutional synergy in urban management, as a collective feature is the byproduct of inter and intra institutional activities of urban organizations. it is consider gregarious action and as managerial phenomenon with feature of trust, participation. cooperation engagement, facilitation, mutual recognition and the network. this article scrutiny the capacity of inters intuitional synergy in urb...

A recent study has suggested that statistical representations of ensemble objects may provide contextual stability to facilitate perception. The present study investigated whether facilitating such perception occurs in the extraction of variability information and how the stability of context mean values influences variability perception. We designed two tasks in which participants directly jud...

Evolutionary psychologists have suggested that our brain is composed of evolved mechanisms. One extensively studied mechanism is the cheater detection module. This module would make people very good at detecting cheaters in a social exchange. A vast amount of research has illustrated performance facilitation on social contract selection tasks. This facilitation is attributed to the alleged auto...

The goals of the present study were (1) to determine whether grammatical gender on a noun modifier can prime recognition of the following noun, (2) to determine whether the priming effect involves facilitation, inhibition, or both, and (3) to compare performance across three different tasks that vary in the degree to which explicit attention to gender is required, including word repetition, gen...

Normal ageing as well as age-associated pathological conditions, such as Alzheimer's disease, are associated with modifications of language processing. In particular, an impaired performance in semantic tasks, associated with relatively spared syntactic processing, has been suggested to be the hallmark of the language disorder of Alzheimer's disease. The present experiment tests semantic and sy...

The difference between Apolipoprotein E ε4 carriers and non-carriers in response to single exercise sessions was tested. Stroop and Posner tasks were administered to young untrained women immediately after walking sessions or moderately heavy exercise. Exercise had a significantly more profound impact on the Stroop effect than on the Posner effect, suggesting selective involvement of prefrontal...

Studies using the single trial Stroop task consistently reveal increased reaction time (RT) facilitation effects among schizophrenia patients. One possible mechanism underlying this effect is increased automatic spreading activation in semantic networks. The current study was designed to test this hypothesis. We administered the Stroop task and two semantic priming tasks to the same subjects. P...
