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.     

Why good guys wear white

Affect is a somewhat abstract concept that is frequently linked to physical metaphor. For example, good is often depicted as light (rather than dark), up (rather than down), and moving forward (rather than backward). The purpose of our studies was to examine whether the association between stimulus brightness and affect is optional or obligatory. In a series of three studies, participants categorized words as negative or positive. The valence of the words and the brightness of the letters were varied orthogonally. In Studies 1, 2, and 3, we found that categorization was inhibited when there was a mismatch between stimulus brightness (e.g., light) and word valence (e.g., negative). Studies 4 and 5 reveal boundary conditions for the effect. The studies suggest that, when making evaluations, people automatically assume that bright objects are good, whereas dark objects are bad.     

Stuck in a rut: perseverative response tendencies and the neuroticism-distress relationship

Clinical views of neuroticism-linked distress often make reference to the perseverative sorts of mental processes that reinforce such experiences. The goal of the present 7 studies, involving 488 undergraduate participants, was to directly examine such perseverative processes. Individual differences in response perseveration were operationalized in terms of choice reaction time difficulties switching (vs. repeating) responses across consecutive trials. Response perseveration interacted with neuroticism in predicting negative emotion, dissatisfaction with life, and displays of negative emotion (Studies 1-4). Specifically, neuroticism-outcome relations were quite a bit stronger at high levels of perseveration. Additional studies (Studies 5-7) provided support for the convergent and discriminant validity of response perseveration. Overall, the results highlight the manner in which response perseveration reinforces experiences of negative emotion.     

The rise and decline of prospective memory performance across the lifespan

In the present study, the trajectory of prospective memory across the lifespan was investigated in a total of 200 participants from five age groups (4- to 6-year-old children, 13- to 14-year-old adolescents, 19- to 26-year-old adults, 55- to 65-year-old adults, and 65- to 75-year-old adults). In an event-based prospective memory task the prospective and the retrospective components were assessed separately. For the prospective component, the results showed better performance for adolescents and young adults than for children and 65- to 75-year-old adults. In addition, participants belonging to the latter group were more likely to forget the retrospective component after having noticed the prospective memory targets. Overall, these results indicate that across the lifespan prospective memory performance follows a similar inverted u-shape function as is well known for retrospective episodic memory.     

Food sharing and perceptions of the status of a relationship

This study examined how individuals may form an impression of the closeness of the relationship between two individuals based on an observation of them sharing food. An opportunity sample of 72 participants watched a video clip of young adults in same-sex or mixed-sex dyads eating a meal together. In the experimental conditions, each member of the dyad also offered or fed a morsel of food to the other person. Analysis showed that food sharing was seen as indicative of familiarity between the members of a dyad. Actually feeding the other person a morsel of food was seen as an indicator of intimacy in male dyads but not in mixed-sex or female dyads. Results are discussed in terms of expectations of intimacy in male and female relationships.     

Bivalency is costly: bivalent stimuli elicit cautious responding

When performing tasks in alternation, substantial slowing occurs when the stimuli have features relevant to both tasks (i.e., when stimuli are bivalent as opposed to univalent). One possible source of this slowing, herein called a bivalency cost, is that encountering bivalent stimuli leads to a more cautious response style. To investigate this, we employed a paradigm that required performing three simple tasks, with bivalent stimuli occasionally encountered on one task. The results show that regardless of the feature overlap among the stimuli used for the different tasks, the introduction of bivalent stimuli slowed responding on all tasks and it was accompanied by a decrease in response errors. Overall, it appears that bivalent stimuli recruit a more cautious approach to task-switching performance.     

Increasing designated driving with a program of prompts and incentives

Designated driving (DD) is a potentially viable but underutilized component of efforts to reduce driving while intoxicated. A reversal design was used to evaluate the effects of prompts and incentives in a bar on the frequency of DD. The results showed an approximate doubling of the number of designated drivers during the two intervention periods.     

The Voice in Dissociation: A Group Model for Helping Victims Integrate Trauma Representational Memory

The current article focuses on the subjective elements of voice in trauma and dissociation, and the manifestation of voice in four phases of group treatment for victims of extreme, catastrophic events. The voice discussed here is no ordinary voice: it captures an attribute of dissociated representational experience that, though not easily defined, is nonetheless replete with trauma messages from the depth of somatopsychic processes, expressed in the patient's nonverbal talking in gestures, tone of voice, posture, silences, facial expressions, and in rhythm, timbre, movement, and syntax. Dissociation, trauma representational memory, and the phases of a proposed group model are discussed in detail with their respective phase-specific voice.     

Mood, self-esteem, and simulated alternatives: thought-provoking affective influences on counterfactual direction

Four studies indicated that moods and self-esteem can influence counterfactual thoughts. This was shown for counterfactuals generated for hypothetical situations (Study 1), for recalled life events (Study 2), and for agreement with counterfactual statements after laboratory tasks (Studies 3 and 4). High self-esteem (HSE) and low self-esteem (LSE) persons generated (Studies 1 and 2) or agreed to (Studies 3 and 4) more downward (worse than actuality) than upward (better than actuality) counterfactuals when in good moods, but they diverged in reactions to bad moods: HSE persons thought more about downward counterfactuals, whereas LSE persons thought more about upward counterfactuals. HSE persons felt better after generating downward counterfactuals (Study 2) and took longer to agree to analogous statements (Studies 3 and 4) in bad moods, suggesting attempts at mood repair.
