Flexibility in conceptual projection constitutes one of the most challenging issues in the embodiment and conceptual metaphor literatures. We sketch a theoretical proposal that places the burden of the explanation on attentional dynamics in interaction with mental models in working memory that are constrained to be maximally coherent. A test of this theory is provided in the context of the conceptual projection of time onto the domain of space. Participants categorized words presented at different spatial locations (back–front, left–right) as referring (...) to the past or to the future. Responses were faster when the irrelevant word location was congruent with the back–past, front–future metaphoric mapping. Moreover, when a new highly task-relevant spatial frame of reference was introduced, it changed the projection of past and future onto space in a way that was congruent with the new frame (past was now projected to left space and future to right space), as predicted by the theory. This study shows that there is substantial flexibility in conceptual projection and opens a venue to study metaphoric variation across tasks, individuals, and cultures as the result of attentional dynamics.

We deal with situations incongruent with our automatic response tendencies much better right after having done so on a previous trial than after having reacted to a congruent trial. The nature of the mechanisms responsible for these sequential congruency effects is currently a hot topic of debate. According to the conflict monitoring model these effects depend on the adjustment of control triggered by the detection of conflict on the preceding situation. We tested whether these conflict monitoring processes can operate implicitly (...) in an implicit learning procedure, modulating the expression of knowledge of which participants are not aware. We reanalyze recently published data, and present an experiment with a probabilistic sequence learning procedure, both showing consistent effects of implicit sequence learning. Despite being implicit, the expression of learning was reduced or completely eliminated right after trials incongruent with the learned sequence, thus showing that sequential congruency effects can be obtained even when the source of congruency itself remains implicit.

We used several cue–target SOAs and three different degrees of cue predictability , to investigate the role of awareness of cue–target predictability on cueing effects. A group of participants received instructions about the informative value of the cue, while another group did not receive such instructions. Participants were able to extract the predictive value of a spatially peripheral cue and use it to orient attention, whether or not specific instructions about the predictive value of the cue were given, and no (...) matter their ability to correctly report it in a post-test questionnaire. In the non-predictive block, bad estimators who received no instructions showed regular cueing effects, while good estimators exhibited smaller and non-significant facilitatory effects at the short SOA and an absence of significant IOR at longer SOAs. However, for the instructions group, the pattern of results reversed. (shrink)

Attention is often dichotomized into controlled vs. automatic processing, where controlled processing is slow, flexible, and intentional, and automatic processing is fast, inflexible, and unintentional. In contrast to this strict dichotomy, there is mounting evidence for context-specific processes that are engaged rapidly yet are also flexible. In the present study we extend this idea to the domain of implicit learning to examine whether flexibility in automatic processes can be implemented through the reliance on contextual features. Across three experiments we show (...) that participants can learn implicitly two complementary sequences that are associated with distinct contexts, and that transfer of learning when the two contexts are randomly intermixed depends on the distinctiveness of the two contexts. Our results point to the role of context-specific processes in the acquisition and expression of implicit sequence knowledge, and also suggest that episodic details can be represented in sequence knowledge.

Synaesthesia has an emotional side. Many synaesthetes have a sense of certainty about the reality and accuracy of their experiences. Consequently, when their synaesthesia is mimicked in real life these synaeshtetes report a positive emotion whereas when the opposite is true, they experience discomfort. Synaesthesia can also be induced by emotions, and emotions can also be the synaesthetic experience. Here we review the research on these types of synaesthesia and study the current evidence for the true nature of these emotions (...) associated to synesthetic perceptions as studied in grapheme-colour synaesthesia. We begin by presenting evidence of how they can be measured in a laboratory setting and proceed to report studies showing that emotions are automatically activated and can vary in degree as a function of certain factors. We lastly review a study showing that these emerging emotions can be so strong and vivid that they can influence attitudes towards otherwise neutral stimuli. We conclude by presenting a model that could account for the findings reported here. (shrink)

Although the majority of literature has shown undistinguishable attentional effects when eye-gaze and arrows are used as cues, recent research has found that whereas eye-gaze selectively orient attention to the specific location or part of the object looked at, arrows unselectively direct attention towards parts of the environment. However, it is unclear whether this dissociation between gaze and arrow cues is related to social cognitive mechanisms such as the attribution of mental states (Theory of Mind, ToM). We aimed at replicating (...) the dissociation between gaze and arrow cues and investigating sex differences in attentional object selection triggered by these two types of stimuli. While we replicated the arrow-gaze dissociation, this was equivalent in the male and female population. This finding seems to run counter the intuition that theory of mind abilities can account for the dissociation observed between gaze and arrow cues since greater ToM abilities have been generally shown in females. However, this conclusion it must be interpreted with caution since no differences in ToM abilities and autistic quotient scores were observed between male and female in our sample. Further research is needed to shed light on this issue. (shrink)
