Plasma viral load is helpful in monitoring systemic HIV infection but the relationship between plasma viral load and CNS functioning remains unclear. Equivocal results have been reported on the relationship between plasma viral load and cognitive functioning. The present study tested cognitive functions with a standardized neuropsychological battery consisting of 28 test scores. Participants (N...

Causal attribution has been one of the most influential frameworks in the literature of achievement motivation, but previous studies considered achievement attribution as relatively deliberate and effortful processes. In the current study, we tested the hypothesis that people automatically attribute their achievement failure to their ability, but reduce the ability attribution in a controlled m...

Cognitive load theory began by using our knowledge of human cognition to devise instructional procedures. Insofar as those procedures have been successful, they have strengthened the cognitive theory that gave rise to them. Indeed, it has been possible to expand our knowledge of cognition by studying the manner in which information can be successfully presented to learners. As a consequence, to...

The “less is more” hypothesis suggests that one reason adults and children differ in their language acquisition abilities is that they also differ in other cognitive capacities: for instance, the relatively poor memory and/or processing abilities of children may make them more likely to over-regularize inconsistent input (Singleton & Newport, 2004; Hudson Kam & Newport, 2005). We investigate th...

Bottom-up processes can interrupt ongoing cognitive processing in order to adaptively respond to emotional stimuli of high potential significance, such as those that threaten wellbeing. However it is vital that this interference can be modulated in certain contexts to focus on current tasks. Deficits in the ability to maintain the appropriate balance between cognitive and emotional demands can ...

In this paper we present the results of a pilot study investigating the impact of stress and cognitive load on the perceived interaction quality of a multimodal dialogue system for crisis management. Four test subjects interacted with the system in four differently configured trials aiming to induce low/high levels of stress and cognitive load. Physiological sensors and subjective ratings were ...

concepts. In addition, the interactive feedback design imposed lower germane cognitive and reflected on learner’s performance. On the practical side, the study contributes to the future study on considering the role of the animated agent in the multimedia design principles for reducing extraneous cognitive load. To elaborate, instructional designers should combine the role of the animated agent...

Much social-cognitive processing is believed to occur automatically; however, the relative automaticity of the brain systems underlying social cognition remains largely undetermined. We used functional MRI to test for automaticity in the functioning of two brain systems that research has indicated are important for understanding other people's behavior: the mirror neuron system and the mentaliz...

The quality assessment of multimodal conversational interactions is determined by many influence parameters. Stress and cognitive load are two of them. In order to assess the impact of stress and cognitive load on the perceived conversational quality it is essential to control their levels during the interaction. Therefore we present in this paper preliminary experiments carried out to determin...
