Distraction and social comparison as mediators of social facilitation effects

Sanders and Baron (Journal of Personality and Social Psychology, 1975, 32, 956–963) suggested that increases in drive produced by the presence of others (social facilitation) are due to the tendency for others to distract task performers as they worked on a task. This Distraction-Conflict theory proposes that socially mediated drive induction will occur whenever there is some reason to shift attention from the task to the social stimuli. In the case of humans, one such reason may be the opportunity to obtain social comparison information from an audience or coactors. The present research demonstrated that social facilitation effects (improved simple task performance and impaired complex task performance produced by the presence of others) occurred only when subjects were motivated to obtain comparison information (Experiment I) and when comparison information was available (Experiment II). The availability of comparison information also led to increased accuracy in estimating the coactor's performance. This indicated that in conditions manifesting social facilitation, subjects were spending some time monitoring the coactor's work, which is an inherently distracting activity. Several supplementary measures of distraction were generally consistent in indicating greater distraction under conditions manifesting social facilitation. The present results offer no support for the explanations of social facilitation suggested by Zajonc and by Cottrell.     

A puzzle about natural laws and the existence of God

The existence of natural laws, whether deterministic or indeterministic, and whether exceptionless or ceteris paribus, seems puzzling because it implies that mindless bits of matter behave in a consistent and co-ordinated way. I explain this puzzle by showing that a number of attempted solutions fail. The puzzle could be resolved if it were assumed that natural laws are a manifestation of God’s activity. This argument from natural law to God’s existence differs from its traditional counterparts in that, whereas the latter seek to explain the fact of natural laws, the former seeks to explain their possibility. The customary objections to the traditional arguments cannot be successfully adapted to counter this new argument, with one exception which has only limited effect. I rebut four claims that the theistic solution to the puzzle about natural laws is paradoxical, though I concede that one of these claims has merit. I consider four objections to the new argument but find three of them more or less unsatisfactory. The fourth, if successful, would undermine our claims to know the truth about the world.     

The Impact Message Inventory–Circumplex (IMI–C): A Replication Study of Its Circumplex Structure in a Dutch Sample

The 56-items Impact Message Inventory–Circumplex (IMI–C) has been developed to describe the interpersonal styles of target persons in terms of the 2-dimensional interpersonal circle, divided in 8 subscales (octants). The IMI–C is based on the assumption that a target person's interpersonal styles can validly be measured by assessing the internal (cognitive and emotional) reactions of the IMI–C respondent (e.g., therapists), interacting with the target person (e.g., psychotherapy patients). This replication study tested the circumplexity of a computer-delivered Dutch IMI–C. The computer-delivered Dutch IMI–C approached circumplexity in a large clinical sample (N = 812) of psychotherapy and psychiatric patients, after removing 3 items from the Submissive octant scale. These 3 items clearly disturbed the IMI–C circumplex structure. It is concluded that, even with the inevitable problem of nested data, circumplexity was approached sufficiently to justify the interpretation of the IMI–C at the octant level, provided that the 3 troublesome Submissive items are removed from the calculations of octant scores. Our replication test of the Dutch IMI–C circumplexity might be an impetus for researchers in the United States to invest in the further validation of the original American version.     

Are community studies of psychological trauma's impact accurate? A study among Jews and Palestinians

We evaluated the accuracy of posttraumatic stress disorder (PTSD) and major depression (MD) diagnoses using brief assessment instruments conducted by phone. PTSD and MD were assessed by telephone interview in a randomly selected sample of Jewish and Palestinian residents of Jerusalem (N = 150) during a period of marked threat of terrorism and war. We utilized the PTSD Symptom Scale Interview Format (Foa, Riggs, Dancu, & Rothbaum, 1993) and the Patient Health Questionnaire-9 (PHQ-9; Kroenke, Spitzer, & Williams, 2001). We then conducted in-depth, in-person interviews within 2 weeks, assessing PTSD and MD using the Composite International Diagnostic Interview (CIDI; Kessler et al., 2004). The prevalence of PTSD and MD diagnosis ascertained by the 2 assessment modalities was similar. Indices of classification accuracy for the phone interview, using the in-person interview as the standard, ranged from modest to high. Brief phone and in-depth in-person measures of PTSD and MD also correlated similarly with other demographic, stress, and coping factors, suggesting convergent validity. Brief phone interviews appear useful for estimating the prevalence of psychological disorders in mass casualty contexts and may have a critical role in both epidemiologic work and guiding public health interventions.     

A review of research on the prevalence,antecedents, consequences and prevention of workplace aggression in clinical medical practice

A broad-ranging review of the published research literature was undertaken on workplace aggression in clinical medical practice. Prevalence studies have found that 15–75% of survey respondents reported verbal aggression and 2–29% reported physical aggression in medical practice settings in the previous 6–24 months. In comparison, there was limited published research on the antecedents and consequences of clinician exposure to workplace aggression, and a dearth of published research on the prevention and minimization of workplace aggression in medical practice settings. Future research efforts need to investigate workplace aggression from all sources and across all medical clinician sub-populations in the diverse settings in which they work. Specific attention needs to be given to identifying key risk and protective factors for workplace aggression exposure, including in relation to clinician profiles, the settings and conditions of medical work, and the presence of key aggression prevention and minimization efforts, both individually and in combination. The impact of workplace aggression on clinician health, well-being, performance and work participation remains under-researched. Overall, a more extensive and robust evidence base is required to enable informed decision-making on reducing the likelihood and consequences of workplace aggression in clinical medical practice.     

The Diabetes Family Behavior Checklist: A Psychometric Evaluation

The Diabetes Family Behavior Checklist (DFBC) assesses supportive and non-supportive parental behavior specific to diabetes management via parent and child reports. The DFBC was administered to 133 children with type 1 diabetes (T1D) and their caregivers. Subsequent analysis verified the two-factor structure of the DFBC corresponding to positive and negative support behaviors. Internal consistency was high for DFBC scores. Moderate to strong correlations with other measures of diabetes-specific familial behaviors, adherence, and metabolic control support the validity of the DFBC. Clinical application of the DFBC is discussed.     

Electrical Stimulation, Endorphins, and the Practice of Clinical Psychology

Recent studies have demonstrated an alternative to drug treatment for patients presenting with anxiety disorders. This new technique involves electrical stimulation of the peripheral nervous system to induce chemical changes in the brain that can support and promote healing. This method was developed in part from studies of ancient Chinese acupuncture, but it is noninvasive and does not require needles, and it does not depend on prescientific rituals or metaphysical theories. Endorphins, natural neuropeptides active in basal brain structures, act upon anxiolytic receptors. Solid evidence from fMRI and neurochemical studies show that a simple office procedure involving electrical stimulation can stimulate the expression of endorphins in the brain. Patients have demonstrated symptom relief from this simple adjunctive treatment with a concomitant reduction in dependency on psychotropic medications.     

Do ad metaphors enhance or dilute the consumers' brand preferences? Exploring the moderating role of goal orientation

This research aims to explore the impacts of ad metaphors and goal orientation on the relationship between brand commitment and attitudes toward the competitor brands. Results show that prevention‐focused consumers with high brand commitment do not exhibit differentially favorable attitudes toward the competitor brands, regardless of ad metaphors. In contrast, prevention‐focused consumers with low brand commitment exhibit more favorable attitudes toward competitor brands advocated by highly metaphorical ads than those advocated by low metaphorical ads. Moreover, promotion‐focused consumers exhibit more favorable attitudes toward competitor brands advocated by highly metaphorical ads than those advocated by low metaphorical ads, regardless of brand commitment.
