Physiological evidence was sought for a center-surround attentional mechanism (CSM), which has been proposed to assist in the retrieval of weakly activated items from semantic memory. The CSM operates by facilitating strongly related items in the "center" of the weakly activated area of semantic memory, and inhibiting less strongly related items in its "surround". In this study weak activation ...

Recent studies challenged the classical notion of automaticity and indicated that even unconscious automatic semantic processing is under attentional control to some extent. In line with our attentional sensitization model, these data suggest that a sensitization of semantic pathways by a semantic task set is necessary for subliminal semantic priming to occur while non-semantic task sets attenu...

Recent work has challenged the previously widely accepted belief that affective processing does not require awareness and can be carried out with more limited resources than semantic processing. This debate has focused exclusively on visual perception, even though evidence from both human and animal studies suggests that existence for nonconscious affective processing would be physiologically m...

We investigated the influence of sentence context on initial integration of novel word meanings into semantic memory. Adults read strongly or weakly constrained sentences ending in known and unknown (novel) words as electrical brain activity was recorded. Word knowledge was assessed via a lexical decision task where recently seen known and unknown word sentence endings served as primes for rela...

Covert face recognition was investigated in a patient with prosopagnosia without object agnosia. This patient performed well in various face processing tasks like expression analysis and feature processing and had relatively preserved semantic knowledge about persons, but was slightly impaired in the visual matching of unfamiliar faces. In face-name paired-associate relearning task, covert face...

Social categorization has been viewed as necessarily resulting in stereotyping, yet extant research suggests the two processes are differentially sensitive to task manipulations. Here, we simultaneously test the degree to which race perception and stereotyping are conditionally automatic. Participants performed a sequential priming task while either explicitly attending to the race of face prim...

Whether unconscious stimuli can modulate the preparation of a cognitive task is still controversial. Using a backward masking paradigm, we investigated whether the modulation could be observed even if the prime was made unconscious in 100% of the trials. In two behavioral experiments, subjects were instructed to initiate a phonological or semantic task on an upcoming word, following an explicit...

The content of spontaneously activated racial stereotypes among White Americans and the relation of this to more explicit measures of stereotyping and prejudice were investigated. Using a semantic priming paradigm, a prime was presented outside of conscious awareness (BLACK or WHITE), followed by a target stimulus requiring a word-nonword decision. The target stimuli included attributes that va...

Although power is often conceptualized as the capacity to influence others, the current research explores whether power psychologically protects people from influence. In contrast to classic social psychological research demonstrating the strength of the situation in directing attitudes, expressions, and intentions, 5 experiments (using experiential primes, semantic primes, and role manipulatio...
