Adults recognize that people can understand more than one language. However, it is unclear whether infants assume other people understand one or multiple languages. We examined whether monolingual and bilingual 20-month-olds expect an unfamiliar person to understand one or more than one language. Two speakers told a listener the location of a hidden object using either the same or two different languages...
A striking asymmetry in human sensorimotor processing is that humans synchronize movements to rhythmic sound with far greater precision than to temporally equivalent visual stimuli (e.g., to an auditory vs. a flashing visual metronome). Traditionally, this finding is thought to reflect a fundamental difference in auditory vs. visual processing, i.e., superior temporal processing by the auditory system...
This study uses motion tracking technology to provide a new way of addressing the development of the ability to prospectively orient objects with respect to one another. A group of toddlers between 16 and 33months of age (N=30) were studied in an object fitting task while they wore reflective markers on their hands to track spatial adjustments in three dimensions. Manual displacements of the handheld...
We examined the impact task interruptions have on visuospatial vigilance in two experiments. In the first experiment participants were randomly assigned to one of three interruptions: participants were given a complete rest (rest), participants completed an alphanumeric vigilance task (letter), or participants performed the primary vigilance task (continuous). In the second experiment participants...
Recent studies have shown enhanced brain and autonomic responses to seeing a face with a direct gaze. Interestingly, greater responses to eye contact vs. averted gaze have been observed when showing “live” faces as stimuli but not when showing pictures of faces on a computer screen. In this study, we provide unequivocal evidence that the differential responses observed in the “live” condition are...
Space perception depends on our motion potentialities and our intended actions are affected by space perception. Research on peripersonal space (the space in reaching distance) shows that we perceive an object as being closer when we (Witt, Proffitt, & Epstein, 2005; Witt & Proffitt, 2008) or another actor (Costantini, Ambrosini, Sinigaglia, & Gallese, 2011; Bloesch, Davoli, Roth, Brockmole,...
Three experiments examined elementary school-aged children’s and adults’ expectations regarding what specialists (i.e., those with narrow domains of expertise) and generalists (i.e., those with broad domains of expertise) are likely to know. Experiment 1 demonstrated developmental differences in the ability to differentiate between generalists and specialists, with younger children believing generalists...
Sequential foreperiod effects in temporal preparation are typically asymmetric such that a previous experience of preparation has a strong impact on participants’ responses to a forthcoming target stimulus presented at the current short rather than at the current long foreperiod. The trace-conditioning model explains this asymmetry by an automatic process of trace-conditioning, which is sufficient...
There is now a large body of evidence showing that many different conditions related to impaired fronto-executive functioning are associated with the enhancement of some types of creativity. In this paper, we pursue the possibility that the central mechanism associated with this effect might be a reduced capacity to exert inhibition. We tested this hypothesis by exhausting the inhibition efficiency...
It is well known that familiar words inhibit each other during spoken word recognition. However, we do not know how and under what circumstances newly learned words become integrated with the lexicon in order to engage in this competition. Previous work on word learning has highlighted the importance of offline consolidation (Gaskell & Dumay, 2003) and meaning (Leach & Samuel, 2007) to establish...
The hypothetical moral dilemma known as the trolley problem has become a methodological cornerstone in the psychological study of moral reasoning and yet, there remains considerable debate as to the meaning of utilitarian responding in these scenarios. It is unclear whether utilitarian responding results primarily from increased deliberative reasoning capacity or from decreased aversion to harming...
Adults tend to believe that objects can function as extensions of people’s selves. This belief has been demonstrated in that changes to people’s sense of self affect their attachment to personally valuable objects, and vice-versa. Here we tested the development of this belief. In Study 1 we found that manipulating 5-year-olds’ self-worth via positive or negative feedback on performance, affected their...
Successful social interaction hinges on accurate perception of emotional signals. These signals are typically conveyed multi-modally by the face and voice. Previous research has demonstrated uni-modal contrastive aftereffects for emotionally expressive faces or voices. Here we were interested in whether these aftereffects transfer across modality as theoretical models predict. We show that adaptation...
A prominent model suggests that individuals to the right of the political spectrum are more cognitively rigid and less tolerant of ambiguity than individuals to the left. On the basis of this model, we predicted that a psychological mechanism linked to the resolution of visual ambiguity – perceptual bias – would be linked to political attitude. Perceptual bias causes western individuals to favour...
The classification of objects to natural categories exhibits cross-person consensus and within-person consistency, but also some degree of between-person variability and within-person instability. What is more, the variability in categorization is also not entirely random but discloses systematic patterns. In this study, we applied the Self-Consistency Model (SCM, Koriat, 2012) to category membership...
In this article, we aim to strengthen the emerging radical, non-representational, approaches to cognitive science by defusing the worries radical enactivists have with the use of information in the ecological approaches – namely the worry that information carries content. We show that Gibson’s later use of the concept is meant to allow for a content-less notion of information, but that the language...
Numerous studies have revealed an asymmetry tied to the perception of coronal place of articulation: participants accept a labial mispronunciation of a coronal target, but not vice versa. Whether or not this asymmetry is based on language-general properties or arises from language-specific experience has been a matter of debate. The current study suggests a bias of the first type by documenting an...
Controlling response parameters like the speed and accuracy of responses allows us to adjust our behavior according to particular situational task demands. We investigated whether exertion of cognitive control over speed–accuracy settings is not exclusively based on conscious representations, but can also be elicited by stimuli that are not consciously represented. Participants were instructed to...
