This is the way: Network perspective on targets for spatial ability development programmes.

Background: Spatial ability (SA) was shown to be important for success in different fields, including STEM. Recent research suggested that SA is a unitary construct, rather than a set of related skills. However, it is not clear how individual differences in different facets of SA emerge, and how they relate to variance in general cognitive ability.

A visual analog of mismatch negativity when stimuli differ in duration.

Event-linked brain potentials were studied in ten essentially healthy volunteers (six men, four women) aged 18-24 years. Subjects were presented with rare deviant and frequent standard visual stimuli in the standard odd-ball paradigm in conditions of active attention to stimulation and in conditions of distracted attention. Differences between deviant stimuli (50, 100, and 150 msec) and standard (200 msec) stimuli ranged from 50 to 150 msec.

[Visual analog of mismatch negativity when stimuli differ in the duration].

Event-related potentials (ERPs) were studied in 10 practically healthy volunteers (6 male, 4 female) aged from 18 to 24 years during presentation of rare deviant and frequent standard visual stimuli in a standard odd-ball paradigm under conditions of active attention and inattention to stimulus duration. The deviation of the duration of deviant stimuli (50, 100 and 150 ms) from that of the standard stimuli (200 ms) varied from 50 to 150 ms. In series where deviations were 100 and 150 ms, a negative difference wave with the latency of 200-400 ms was revealed (ERP to the deviant stimulus under conditions of inattention minus ERP to the control stimulus of the same duration) mainly in the right temporal region.
