Stimulus presentation order in receptive identification tasks: A systematic replication

Conflicting recommendations exist in the literature regarding the optimal order of stimulus presentation when teaching auditory–visual conditional discriminations. The present study examined the generality of a previously demonstrated advantage of presenting the auditory sample before visual comparisons (sample‐first condition) over the reverse sequence (comparison‐first condition). Participants were four typically developing 5‐ and 6‐year‐old boys. The procedures of Petursdottir and Aguilar (2016) were systematically replicated with the addition of a prompted error correction trial following each incorrect response. Overall, there were more instances of quicker mastery in the sample‐first condition (four of seven evaluations) than in the comparison‐first condition (two of seven evaluations). A comparison‐first advantage was associated with slower acquisition in both conditions than in the remaining evaluations, and an analysis of stimulus and position bias yielded tentative evidence for unwanted sources of stimulus control.     

Regional Analyses of Alcohol and Suicide in Norway: Some Empirical Considerations

The association between alcohol consumption and suicide was analyzed on aggregate-level data from Norway, applying regional units in the analyses. Thereby two purposes could be served: to validate previous estimates derived from time series analyses, and to assess an empirical indication of alcohol and suicide as alternative solutions. The effect of alcohol consumption on suicide rates tended to be higher for women than for men, which is contrary to results from time series analyses and what might generally be expected. The results are discussed with reference to causal mechanisms and alcohol and suicide as alternative choices of action, and methodological considerations are outlined.
