The role of selective attention in visual awareness of stimulus features: Electrophysiological studies

Attention and awareness are closely related, but the nature of their relationship is unclear. The present study explores the timing and temporal evolution of their interaction with event-related potentials. The participants attended to specific conjunctions of spatial frequency and orientation in masked (unaware) and unmasked (aware) visual stimuli. A correlate of awareness appeared 100-200 msec from stimulus onset similarly to both attended and unattended features. Selection negativity (SN), a correlate of attentional selection, emerged in response to both masked and unmasked stimuli after 200 msec. This double dissociation between correlates of awareness and SN suggests that the electrophysiological processes associated with feature-based attentional selection and visual awareness of features can be dissociated from each other at early stages of processing. In a passive task, requiring no attention to the stimuli, early electrophysiological responses (before 200 msec) related to awareness were attenuated, suggesting that focal attention modulates visual awareness earlier than does selective feature-based attention.     

Effects of the School-to-Work Group Method among young people

This study examines effects of the School-to-Work Group Method among 17-25-year-old young people facing the transition from vocational college to work. After baseline measurement (N = 416) participants were randomized into experimental and control groups. The results of ten month follow-up (N = 334) showed notable beneficial impacts of the group method on both employment itself and on how well it matched participants’ education and personal career plans. The group method also had a significant preventive effect on psychological distress and depression symptoms among those initially at risk of suffering from mental disorder. Moreover, it considerably increased participants’ personal work life, finances and property goals.
