“…We applied a mixed-effects model of the analysis of variance (ANOVA) that allowed a flexible dependency structure for the model and did not exclude the participant when a missing value was encountered (Gueorguieva & Krystal, 2004). Separate mixedmodel ANOVAs were calculated for P3a and P3b responses.…”

Neurocognitive studies have shown that extensive musical training enhances P3a and P3b event-related potentials for infrequent target sounds, which reflects stronger attention switching and stimulus evaluation in musicians than in nonmusicians. However, it is unknown whether the short-term plasticity of P3a and P3b responses is also enhanced in musicians. We compared the short-term plasticity of P3a and P3b responses to infrequent target sounds in musicians and nonmusicians during auditory perceptual learning tasks. Target sounds, deviating in location, pitch, and duration with three difficulty levels, were interspersed among frequently presented standard sounds in an oddball paradigm. We found that during passive exposure to sounds, musicians had habituation of the P3a, while nonmusicians showed enhancement of the P3a between blocks. Between active tasks, P3b amplitudes for duration deviants were reduced (habituated) in musicians only, and showed a more posterior scalp topography for habituation when compared to P3bs of nonmusicians. In both groups, the P3a and P3b latencies were shortened for deviating sounds. Also, musicians were better than nonmusicians at discriminating target deviants. Regardless of musical training, better discrimination was associated with higher working memory capacity. We concluded that music training enhances short-term P3a/ P3b plasticity, indicating training-induced changes in attentional skills.

Linking card sorting to browsing performance – are congruent municipal websites more efficient to use?

Card sorting is a method for eliciting mental models and is frequently used for creating efficient website navigation structures. The present studies set out to validate card sorting by linking browsing performance to the degree of match between the mental model and the navigation structure. First, a card sorting study was conducted (n = 27) to elicit users' mental model of municipal websites. Second, performance was measured for a number of search tasks with varying degrees of congruence with users' mental model (n = 50). Analysis by linear mixed-effect models suggests that the match between mental model and website structure has no effect on browsing performance. We discuss possible reasons and consequences of the failure to validate card sorting for designing navigation structures of informational websites. ARTICLE HISTORY

“…Again, choosing a primary outcome measure, a standard practice in clinical trials, is commonly employed based on a plan to use simple analysis of variance models for examining change due to intervention, rather than selecting data analysis strategies that match the complexity of the measurement problem (Gueorguieva and Krystal 2004;Jacobson and Truax 1991). The basic problem is that ''it is difficult to argue that adequate examination of such complex constructs can be captured with a single indicator '' (De Los Reyes and Kazdin 2006, p. 556).…”

A consistent result in the evaluation of groupdelivered intervention to promote social reciprocity in children with PDDs is that outcome data are inconclusive. Lack of robust evidence of efficacy confounds understanding of these interventions and their value to the field. It is conceivable that the construct of impaired social reciprocity in PDD presents unique circumstances that require special consideration when evaluating the evidence base. Social reciprocity and impairment in social functioning are complex constructs, which require a multi-dimensional, multi-method approach to intervention and measurement of gains. The existing paradigm for evaluating the evidence base of intervention may need modification to permit a more intricate analysis of the extant research, and increase the sophistication of future research.
