A process-specific approach in the study of normal aging deficits in cognitive control
Bearing in mind that cognitive control is a complex function that includes several processes, it is not clear exactly which ones deteriorate with age. In fact, controversial results have been found. For example, some studies indicate that age-related deficits are observed in proactive and not in reactive control, others show that it is reactive control that is impaired and not proactive control, and some studies find no deficits at all (e.g., Kop…

Attention and its coupling to action
We discuss two commentaries that we have received on our target article (Humphreys et al ., 2010). We elaborate on the evidence for action effects on extinction and discuss whether these effects occur pre or post the selection of a response. In addition, we discuss the neural basis of the effects of action relations on extinction and on the generalization of results on action relations to real‐world examples
The interaction of attention and action
We discuss evidence indicating that human visual attention is strongly modulated by the potential of objects for action. The possibility of action between multiple objects enables the objects to be attended as a single group, and the fit between individual objects in a group and the action that can be performed influences responses to group members. In addition, having a goal state to perform a particular action affects the stimuli that are selec…
The Dynamics of Category Conjunctions
In three experiments we investigated the dynamics of impression formation when perceivers encounter unsurprising (e.g. male mechanic) versus surprising (e.g. female mechanic) social category conjunctions. In Experiment 1, participants took longer to form an impression of targets described using a surprising versus an unsurprising conjunction of categorizations. In Experiment 2, we investigated the stages during which impressions of category conju…
Studies of adults can inform accounts of theory of mind development
There is strong evidence that developments in children's theory of mind (ToM) at 3?4 years are related to developments in language and executive function. However, these relationships might exist for 2 reasons. First, language and executive function might be necessary for the mature ToM abilities that children are in the process of developing. Second, language and executive function may be necessary for developing ToM but have no necessary role i…
Cognitive Ethology for humans
We discuss Kingstone et al.'s target article in the light of emerging work on cognitive ethology
Bilingual language switching and the frontal lobes
Bilinguals typically show a cost of switching between their two languages. When asked to name single numerals rapidly and unpredictably in one or the other language, nonbalanced bilinguals demonstrate markedly slower responses on switch trials. This language switching cost is consistently larger when switching to the speaker's stronger, dominant language (L 1 ), resulting in a crossover such that L 1 responses are slower. To ascertain the brain m…
Visual search within and across dimensions
We used a visual search task in which participants searched for the presence of either both members or just one member of pairs of spatially separated simple visual features. Pairs of target features could be drawn either from within the same dimension (two colours, or two orientations) or from across two different dimensions (one colour and one orientation). In Experiment 1, display items carrying target and non‐target features (target and distr…
A connectionist model of alexia
A connectionist model was developed to simulate the production of phonological, semantic and orthographic lexical representations from an orthographic input code. When lesioned, the network displayed many of the characteristics of the neurological disorder, pure alexia. These included: greater accuracy in the recognition of letters compared to words, and (in some cases) spared semantic categorization and lexical decision ability relative to namin…
Visual search and stimulus similarity.
A new theory of search and visual attention is presented. Results support neither a distinction between serial and parallel search nor between search for features and conjunctions. For all search materials, instead, difficulty increases with increased similarity of targets to nontargets and decreasedsimilarity between nontargets, producing a continuum of search efficiency. A parallel stage of perceptual grouping and description is followed by com…
Direct vs. indirect tests of the information available from masked displays
A comparison was made between two procedures for testing whether an alpha‐numeric character, which was pattern masked to prevent awareness, could access higher‐order information concerning its category. In the indirect test, subjects made categorization responses to a letter or digit target which was immediately preceded by a masked letter or digit stimulus. In the direct test, the target stimulus was not presented; nevertheless, categorization r…
