Selective attention is a fundamental cognitive function that guides behavior by selecting and prioritizing salient or relevant sensory information of our environment. Despite early evidence and theoretical proposal pointing to an implication of thalamic control in attention, most studies in the past two decades focused on cortical substrates, largely ignoring the contribution of subcortical regions as well as cortico-subcortical interactions. Here, we suggest a key role of the pulvinar in the selection of salient and relevant information via its involvement in priority maps computation. Prioritization may be achieved through a pulvinar- mediated generation of alpha oscillations, which may then modulate neuronal gain in thalamo-cortical circuits. Such mechanism might orchestrate the synchrony of cortico-cortical interaction, by rendering neural communication more effective, precise and selective. We propose that this theoretical framework will support a timely shift from the prevailing cortico- centric view of cognition to a more integrative perspective of thalamic contributions to attention and executive control processes.

The ability to exert control over automatic behavior is of particular importance as it allows us to interrupt our behavior when the automatic response is no longer adequate or even dangerous. However, despite the literature that exists on the effects of practice on brain activation, little is known about the neuroanatomy involved in reestablishing executive control over previously automatized behavior. We present a visual search task that enabled participants to automatize according to defined criteria within about 3 hr of practice and then required them to reassert control without changing the stimulus set. We found widespread cortical activation early in practice. Activation in all frontal areas and in the inferior parietal lobule decreased significantly with practice. Only selected prefrontal (Brodmann's areas [BAs] 9/46/8) and parietal areas (BAs 39/40) were specifically reactivated when executive control was required, underlining the crucial role of the dorsolateral prefrontal cortex in executive control to guide our behavior.

We examine the effects of different types of executive incentives on technological innovation of declining firms and the moderating effects of the degree of decline and organisational slack on executive incentives and enterprise technological innovation. We also assess the synergetic effects of different types of executive incentives on technological innovation of declining enterprises. We find the following: first, executive compensation incentive, equity incentive and control incentives are beneficial to promote technological innovation in declining enterprises. Second, the degree of decline negatively moderates the relationship between equity incentive and technological innovation. Third, organisational slack positively moderates the relationship between equity incentive and technological innovation, as well as the relationship between control incentives and technological innovation, especially for severely declining enterprises. Fourth, there are synergistic effects between executive control incentive and compensation incentive, control incentives and equity incentive on technological innovation. The contributions are as follows: first, taking declining enterprises as sample, we suggest that to increase the role of compensation incentive and equity incentive in promoting technological innovation in declining enterprises, the control incentives should be strengthened. Second, organisational slack should be fully exploited for severely declining enterprises so that executives should have the motivation and conditions to carry out technological innovation and further help declining enterprises to turnaround successfully.

Healthy development can be viewed as an important dimension of the general wellbeing index and can be based upon lifelong sustainable satisfaction. Young individuals can represent an important component for society and its development. The literature shows that increased levels of global life satisfaction (LS) can be associated with minimal levels of problematic behaviors and elevated levels of pro-social behaviors. However, low levels of LS can be associated with high levels of perceived loneliness (PL), which, in turn, can be associated with antisocial behavior (AS). In light of this, the current investigation aims to study the mediating effect of PL and the link between LS and AS. This study is a preliminary investigation referring to aggressive behaviors and cognition in relation to subjective wellbeing. The sample consisted of 81 young individuals (M = 27.57, Standard Deviation = 9.25) from Aurel Vlaicu University of Arad, Romania. AS was evaluated with the How I Think Questionnaire (HIT), PL was measured with a single item inquiry and LS was evaluated with the satisfaction with life scale (SWLS). The results display that there is a powerful association between LS and AS, between LS and PL and between PL and AS. After the inclusion of the mediator (PL) to the model, the influence of the independent variable (LS) increased and the effect of LS on AS significantly decreased. In light of this, the relationship between LS and AS can be explained by the mediating role of the PL variable. The results indicate the importance of perceived loneliness in regard to one’s life satisfaction and antisocial behaviors. In light of this, interventions that focus on the social aspect could prove useful for the improvement of sustainable life satisfaction, therefore decreasing the chance of the emergence of AS.
