More than one type of probability must be considered when making decisions. It is as necessary to know one's chance of performing choices correctly as it is to know the chances that desired outcomes will follow choices. We refer to these two choice contingencies as internal and external probability. Neural activity across many frontal and parietal...

Is visual reinterpretation of bistable figures (e.g., duck/rabbit figure) in visual imagery possible? Current consensus suggests it is in principle possible because of converging evidence of quasi-pictorial functioning of visual imagery. Yet, studies that have directly tested and found evidence for reinterpretation in visual imagery, allowing for t...

In two experiments, we examined the role of gesture in reinterpreting a mental image. In Experiment 1, we found that participants gestured more about a figure they had learned through manual exploration than about a figure they had learned through vision. This supports claims that gestures emerge from the activation of perception-relevant actions d...

Background We examined a new method to encourage interviewees to say more, the ghostwriter method, and examined its effect on eliciting information and cues to deceit. Method A total of 150 truth tellers and liars either told the truth about a trip they made in the last 12 months or pretended to have made such a trip. They were allocated to a Cont...

In the current confirmatory study, we conducted two experiments that examined the role of gesture in reinterpreting a mental image. In the first experiment, we observed that participants gestured more about figures they had learned through manual exploration than about figures they had learned through vision. Experiment 2 investigated whether such...

A classic discussion about visual imagery is whether it affords reinterpretation, like discovering two interpretations in the duck/rabbit illustration. Recent findings converge on reinterpretation being possible in visual imagery, suggesting functional equivalence with pictorial representations. However, it is unclear whether such reinterpretations...
