“…However, the similar pattern of results obtained in Experiment 1 and 2 indicates that contextual multiplication problems did not influence the retrieval of multiplication facts when participants resolved addition problems. This finding is particularly odd because it is usually found that when participants are engaged in a number cognition tasks (i.e., number comparison) their performance is modulated by the type and number of filler trials used in the experiment (Huber, Mann, Nuerk, & Moeller, 2014;Macizo & Herrera, 2011. Several explanations might be offered for the lack of contextual effects in our study.…”

In two experiments we evaluated the coactivation of arithmetic facts and the possible inhibitory mechanism used to select the correct one. To this end, we introduced an adapted version of the negative priming paradigm in which participants received additions and they decided whether they were correct or not. When the addition was incorrect but the result was that of multiplying the operands (e.g., 2 + 4 = 8), participants took more time to respond relative to control additions with unrelated results. This finding corroborated that participants coactivated arithmetic facts of multiplications even when they were irrelevant to perform the task. Moreover, the participants were slower to respond to an addition whose result was that of multiplying the operands of the previous trial (e.g., 2 + 6 = 8). These results support the existence of an inhibitory mechanism involved in the selection of arithmetic facts.

“…Similar to what we have commented in the previous section with the Stroop task, there is recent evidence suggesting that individuals adapt to conflict situations in numerical cognition (Huber, Mann, Nuerk, & Moeller, 2014;Huber, Moeller, Nuerk, Macizo, Herrera, & Willmes, 2013;Macizo & Herrera, 2011aMoeller, Klein, & Nuerk, 2013). Macizo and Herrera (2011a) evaluated whether the compatibility effect was modulated by the relevance of units across the experimental task.…”

“…The results showed that the compatibility effect was large when the relevance of units was biased by increasing the percentage of within-decade comparisons (i.e., 46-48, filler trials in the experiment) whose resolution required the processing of units. Huber et al (2014) found converging evidence of contextual effects depending on the proportion of within-decade filler trials. In an eye-tracking study, the authors manipulated the percentage of within-decade fillers (25, 50, and 75 %).…”

Conflict resolution in two-digit number processing: evidence of an inhibitory mechanism

We investigated the mechanism involved in conflict resolution when individuals processed two-digit numbers. Participants performed a comparison task in blocks of two trials. In the first trial, between-decade two-digit numbers were used in a compatible condition where the decade and the unit of one number were larger than those of the other number (i.e., 21-73) and an incompatible condition where the decade of one number was larger but the unit was smaller than those of the other number (i.e., 61-53). In the second trial, within-decade two-digit numbers were presented in a related condition where the numbers contained the units presented previously (i.e., 41-43) and an unrelated condition with units that did not appear before (i.e., 48-49). In the first trial, participants responded more slowly in incompatible trials relative to compatible trials. In the second trial, participants were slower in the related condition relative to unrelated trials only after incompatible trials. These results suggest that participants experienced conflict in the incompatible condition of first trial and that they inhibited irrelevant units to resolve conflict.

“…Their results showed that when the unit digits became more relevant than the decade digits (70% same-decade comparisons) the compatibility effect shifted from negative to positive. A recent study by Huber et al (2013) provided the first eye-tracking evidence to indicate that the compatibility effect increases with the percentage of same-decade filler items (i.e., 25%, 50%, and 75%) which was accompanied by less fixations on tens and more fixations on units.…”

“…Recent work indicates that the compatibility effect is influenced by the relevance of the rightmost unit digit processing during the comparison task (Huber, Mann, Nuerk, & Moeller, 2013;Macizo & Herrera, 2011). In their study, Macizo and Herrera (2011) heightened the relevance of unit processing by increasing the percentage (i.e., 20%, 50%, and 70%) of same-decade filler items (e.g., 52_58) in the stimulus set.…”

Flexible and unique representations of two-digit decimals

We examined the representation of two-digit decimals through studying distance and compatibility effects in magnitude comparison tasks in four experiments. Using number pairs with different leftmost digits, we found both the second digit distance effect and compatibility effect with two-digit integers but only the second digit distance effect with two-digit pure decimals. This suggests that both integers and pure decimals are processed in a compositional manner. In contrast, neither the second digit distance effect nor the compatibility effect was observed in two-digit mixed decimals, thereby showing no evidence for compositional processing of two-digit mixed decimals. However, when the relevance of the rightmost digit processing was increased by adding some decimals pairs with the same leftmost digits, both pure and mixed decimals produced the compatibility effect. Overall, results suggest that the processing of decimals is flexible and depends on the relevance of unique digit positions. This processing mode is different from integer analysis in that two-digit mixed decimals demonstrate parallel compositional processing only when the rightmost digit is relevant. Findings suggest that people probably do not represent decimals by simply ignoring the decimal point and converting them to natural numbers.
