The mere activation of the idea of a behavioral act moves the human body without the person consciously deciding to take action. In an experiment, we showed that people subliminally primed with the concept of exertion were faster to squeeze a hand grip forcefully but expended more effort when the subliminal primes were directly accompanied by consciously visible positive stimuli. These findings...

Four studies examined primed and chronic autonomous and heteronomous motivations. Study 1 showed that autonomy and heteronomy can be primed and influence perceptions and behavior in a way consistent with consciously regulated motives. In Study 2, a measure of chronic motivation was developed and its construct validity and reliability were assessed. In Study 3, the chronicity measure predicted b...

Our experience with the world is shaped not only directly through personal exposure but also indirectly through observing others and learning from their experiences. Using a conditioning paradigm, we investigated how directly and observationally learned information can affect pain perception, both consciously and non-consciously. Differences between direct and observed cues were manifest in hig...

For many years, research has been done to find the best way to make decisions. Dijksterhuis and Nordgren (2006) formulated the Unconscious Thought Theory (UTT), stating that when making complex decisions it is better not to think consciously, but to direct your attention elsewhere, letting the unconscious make the decision. However, a wealth of research has found evidence against the prediction...

In the metacontrast dissociation procedure, presenting a masked shape prime prior to a visible shape target leads to reaction-time effects of the prime in an indirect measure, although participants cannot consciously detect prime shapes in a direct measure (Klotz & Neumann, 1999). This has been taken as evidence for the processing of unconscious input. The results of the present metacontrast di...

Syntax is the core computational component of language. A longstanding idea about syntactic processing is that it is generally not available to conscious access, operating autonomously and automatically. However, there is little direct neurocognitive evidence on this issue. By measuring event-related potentials while human observers performed a novel cross-modal distraction task, we demonstrate...

Conscious processing is generally seen as required for flexible and willful actions, as well as for tasks that require durable information maintenance. Here we present research that questions the assumption that only consciously perceived information is durable (>500 ms). Using the attentional blink (AB) phenomenon, we rendered otherwise relatively clearly perceived letters non-conscious. In a ...

Common wisdom holds that choice decisions are based on conscious deliberations of the available information about choice options. On the basis of recent insights about unconscious influences on information processing, we tested whether automatic mental associations of undecided individuals bias future choices in a manner such that these choices reflect the evaluations implied by earlier automat...
