Preferences and inferences in encoding visual objects: a systematic comparison of semantic and affective priming.

The authors systematically compared semantic and affective priming in five studies involving words and pictures. In Studies 1 (lexical decision task) and 2 (evaluation task), irrelevant short duration (200 ms) primes were briefly flashed before relevant targets. The authors orthogonally varied both the semantic and affective relations between primes and targets. In both studies, semantic priming but not affective priming was found. Study 3 revealed that the same stimuli can produce affective priming, but only when words come from a single semantic category. Studies 4 and 5 used pictures rather than words to examine automatic encoding tendencies. The results conceptually replicated those from Studies 1 and 2. In sum, the findings suggest that affective priming may be a relatively fragile phenomenon, particularly when the semantic properties of objects vary in a salient manner.

Are we puppets on a string? The contextual meaning of unconscious expressive cues.

In three studies, the authors show that unconscious expressive cues can lead to opposite evaluations, depending on the context in which they occur. In Study 1, brow (vs. cheek) tension reduced preferences in an easy judgment context but increased preferences in a difficult context. In Study 2, head shaking (vs. nodding) either increased or decreased prosocial affect depending on the context in which the judged character was presented. In Study 3, a subliminal smile (vs. frown) led to higher self-ratings of performance when paired with one's own actions but to lower self-ratings of performance when paired with a competitor's actions. Together, these results suggest that the meaning of unconscious expressive cues is not fixed.

Does quick to blame mean quick to anger? The role of agreeableness in dissociating blame and anger.

Two studies investigated agreeableness, the accessibility of blame, and their potential interactive effects on anger. To measure the chronic accessibility of blame, a choice reaction time task was created that required participants to classify words as blameworthy or not. It was found that for individuals low in agreeableness, blame accessibility was positively related to anger and arguments during the course of daily life, hostile feelings during the course of a semester, and anger in response to a short video involving a blameworthy action. This same straightforward relationship between the accessibility of blame and anger did not characterize those high in agreeableness. The results suggest that agreeableness plays an important role in facilitating (low agreeableness) or inhibiting (high agreeableness) the link between accessible blame and anger.

Watch out! That could be dangerous: valence-arousal interactions in evaluative processing.

Seven studies involving 146 undergraduates examined the effects of stimulus valence and arousal on direct and indirect measures of evaluative processing. Stimuli were emotional slides (Studies 1 to 6) or words (Study 7) that systematically varied in valence and arousal. Evaluative categorization was measured by reaction times to evaluate the stimuli (Studies 2, 3, and 7), latencies related to emotional feelings (Study 3), and incidental effects on motor performance (Studies 4 and 5). A consistent interaction was observed such that evaluation latencies were faster if a negative stimulus was high in arousal or if a positive stimulus was low in arousal. Studies 1, 6, and 7 establish that the findings are not due to stimulus identification processes. The findings therefore suggest that people make evaluative inferences on the basis of stimulus arousal.

Trait as default: extraversion, subjective well-being, and the distinction between neutral and positive events.

On the basis of prior work suggesting that trait self-knowledge serves a "fill-in" function when event-specific information is missing (M.D. Robinson & G. L. Clore, 2002a), we sought to demonstrate that extraversion is a more reliable predictor of subjective well-being (SWB) judgments among certain individuals than among others. Four studies involving a total of 260 participants revealed that the extraversion-SWB relation was relatively weaker among those quick to appreciate the distinction between neutral and positive events in a choice reaction-time task; by contrast, it was stronger among those slow to recognize this distinction. The findings suggest that extraversion scales measure (among other things) beliefs about SWB that differentially contribute to judgments among those less capable of making evaluative distinctions at encoding.

Rehabilitation of peripheral nerve injuries.

Traumatic injuries to peripheral nerves pose complex challenges to both military and civilian physicians. Treatment of nerve injuries must consider all aspects of the inherent disability. Pain control is of paramount importance. Little will be accomplished until pain is brought down to tolerable levels. Rehabilitation needs to be instituted as first-line treatment. Focus must be first placed on protection of the affected area from complications stemming from disuse and immobility and then on enhancement of strength, flexibility, sensory discrimination, and dexterity. Early intervention sets the stage for optimal physiologic and functional recovery.

The epistemic benefits of trait-consistent mood states: an analysis of extraversion and mood.

One must consider both trait and state affect to predict individual differences in emotional processing. The present results document a novel trait-state interaction that is consistent with proposals concerning the epistemic functions of affect (A. R. Damasio, 1994). Four studies tested the effects of extraversion and mood on motivation-relevant processing. Study 1 measured naturally occurring mood, whereas Studies 2-4 manipulated mood. Extraverts were faster to link events to their personal motivations when in a positive mood state, whereas introverts were faster to do so in a neutral or negative mood state. Further findings indicate that this interaction affects attitude accessibility rather than event elaboration. Overall, the authors suggest that there are pragmatic benefits to trait-consistent moods, particularly for processing motivation-relevant stimuli.

Belief and feeling: evidence for an accessibility model of emotional self-report.

This review organizes a variety of phenomena related to emotional self-report. In doing so, the authors offer an accessibility model that specifies the types of factors that contribute to emotional self-reports under different reporting conditions. One important distinction is between emotion, which is episodic, experiential, and contextual, and beliefs about emotion, which are semantic, conceptual, and decontextualized. This distinction is important in understanding the discrepancies that often occur when people are asked to report on feelings they are currently experiencing versus those that they are not currently experiencing. The accessibility model provides an organizing framework for understanding self-reports of emotion and suggests some new directions for research.

Episodic and semantic knowledge in emotional self-report: evidence for two judgment processes.

Three studies involving 3 participant samples (Ns = 39, 55, and 53) tested the hypothesis that people retrieve episodic emotion knowledge when reporting on their emotions over short (e.g., last few hours) time frames, but that they retrieve semantic emotion knowledge when reporting on their emotions over long (e.g., last few months) time frames. Support for 2 distinct judgment strategies was based on judgment latencies (Studies 1 and 2) and priming paradigms (Studies 2 and 3). The authors suggest that self-reports of emotion over short versus long time frames assess qualitatively different sources of self-knowledge.
