“…However, PD-MCI patients and aMCI+ patients showed lower performances than controls on Stroop Interference/Time, by suggesting that inhibitory control represents a critical domain more frequently affected in mild cognitive disorders (cfr. Bélanger et al 2010). Moreover, Santangelo et al (2015) have recently suggested that among cognitive measures, the Stroop Test may be useful even for identifying patients at high risk of developing PD-MCI at the time of PD diagnosis, by suggesting that an impairment of inhibitory control might represent an early cognitive deterioration in the course of the disease.…”

“…Along the same lines, a good way to manipulate prepotency strength in this paradigm is to vary the proportion of congruent versus incongruent items. In fact, research has shown that the interference effect of incongruent items increases with the proportion of congruent trials in the experiment (Bélanger et al, 2010;Kane and Engle, 2003;Zbrodoff, 1979, 1998). Indeed, in the context of pure blocks of incongruent items, the inappropriate prepotent reading strategy is never reinforced, and it is therefore easier to perform such blocks than blocks containing an increasing proportion of congruent items in which goal maintenance abilities are more and more challenged.…”

Influence of response prepotency strength, general working memory resources, and specific working memory load on the ability to inhibit predominant responses: A comparison of young and elderly participants. Brain and Cognition (in press). 2 AbstractOne conception of inhibitory functioning suggests that the ability to successfully inhibit a predominant response depends mainly on the strength of that response, the general functioning of working memory processes, and the working memory demand of the task (Roberts, Hager, and Heron, 1994). The proposal that inhibition and functional working memory capacity interact was assessed in the present study using two motor inhibition tasks (Go/No-Go and response incompatibility) in young and older participants. The strength of prepotency was assessed with a short or long training phase for the response to be inhibited. The influence of working memory resources was evaluated by administering the tasks in full versus divided attention conditions. The effect of working memory load was manipulated by increasing the number of target and distracter items in each task. Results showed no effect of prepotency strength, whereas dividing attentional resources and increasing working memory load were associated with greater inhibitory effects in both groups and for both tasks. This deleterious effect was higher for older participants, except in the working memory load condition of the Go/No-Go task. These results suggest an interactive link between working memory and response inhibition by showing that taxing working memory resources increases the difficulty of inhibiting prepotent responses in younger and older subjects. The additional detrimental effect of these factors on healthy elderly subjects was related to their decreased cognitive resources and to their shorter span size.

“…This effect has traditionally been studied at a global or list-wide level by comparing performance on congruent and incongruent blocks, namely blocks containing a majority of congruent or incongruent items, respectively [10,11]. The standard interpretation of this phenomenon postulates that the inhibition of the word reading process varies depending on task context [e.g., 9,12], with a decreased influence of the word reading process for all the items (congruent and incongruent) presented during mostly incongruent blocks compared to mostly congruent blocks.…”

Exploration of the mechanisms underlying the ISPC effect: Evidence from behavioral and neuroimaging data

The item-specific proportion congruent (ISPC) effect in a Stroop task -the observation of reduced interference for color words mostly presented in an incongruent color -has attracted growing interest since the original study by Jacoby [1]. Two mechanisms have been proposed to explain the effect: associative learning of contingencies and itemspecific control through word reading modulation. Both interpretations have received empirical support from behavioral data. Therefore, the aim of this study was to investigate the responsible mechanisms of the ISPC effect with the classic two-item sets design using fMRI.Results showed that the ISPC effect is associated with increased activity in the anterior cingulate (ACC), dorsolateral prefrontal (DLPFC), and inferior and superior parietal cortex.Importantly, behavioral and fMRI analyses specifically addressing the respective contribution of associative learning and item-specific control mechanisms brought support for the contingency learning account of the ISPC effect. Results are discussed in reference to task and procedure characteristics that may influence the extent to which item-specific control and/or contingency learning contribute to the ISPC effect.
