Without mercy: the immediate impact of group size on lynch mob atrocity

Two independent research traditions have focused on social contributions to lynching. The sociological power threat hypothesis has argued that lynching atrocity will increase as a function of the relative number of African Americans. The psychological self-attention theory has argued that lynching atrocity will increase as a function of the relative number of mob members. Two series of analyses (one using newspaper reports and the second using photographic records) using different and nonoverlapping samples of lynching events rendered a consistent pattern of results: Lynch mob atrocity did not increase as a function of the relative numbers of African Americans in the county population but it did increase as a function of the relative numbers of mob members in the lynch mob. Discussion considers the implications of these results.     

Jealousy,Infidelity, and the Difficulty of Diagnosing Pathology: A CBT Approach to Coping with Sexual Betrayal and the Green-Eyed Monster

Humans have evolved adaptations for infidelity, as well defenses against a partner’s betrayal—centrally the emotion of jealousy. Both create problems that bring couples to therapy. Diagnosing jealousy as pathological versus normal turns out to be difficult, in part because infidelity has evolved to be concealed from the betrayed mate, which creates a signal detection problem. Because missing an infidelity committed by a mate has been more costly in evolutionary currencies than falsely suspecting a partner of cheating, selection has created an error management cognitive bias to over-infer a partner’s betrayal. Moreover, adaptations for jealousy become activated by predictors of infidelity, such as mate value discrepancies, when no actual infidelities have occurred. Cognitive-behavior therapy (CBT) offers several ways to deal with these complexities. One way is to highlight potential mismatches, distinguishing between jealous emotions that were functional in ancestral environments but are less so in modern environments. A second is to distinguish between the goal of personal well-being and reproductive outcomes. Understanding the evolutionary logic of jealousy, in short, provides patients with conceptual tools for cognitively reframing jealousy and infidelity.     

Relations between emotion,memory, and attention: Evidence from taboo Stroop,lexical decision,and immediate memory tasks

This article reports five experiments demonstrating theoretically coherent effects of emotion on memory and attention. Experiments 1-3 demonstrated three taboo Stroop effects that occur when people name the color of taboo words. One effect is longer color-naming times for taboo than for neutral words, an effect that diminishes with word repetition. The second effect is superior recall of taboo words in surprise memory tests following color naming. The third effect is better recognition memory for colors consistently associated with taboo words rather than with neutral words. None of these effects was due to retrieval factors, attentional disengagement processes, response inhibition, or strategic attention shifts. Experiments 4 and 5 demonstrated that taboo words impair immediate recall of the preceding and succeeding words in rapidly presented lists but do not impair lexical decision times. We argue that taboo words trigger specific emotional reactions that facilitate the binding of taboo word meaning to salient contextual aspects, such as occurrence in a task and font color in taboo Stroop tasks.     

Pragmatism, Artificial Intelligence, and Posthuman Bioethics: Shusterman, Rorty, Foucault

Michel Foucault's early works criticize the development of modern democratic institutions as creating a surveillance society, which functions to control bodies by making them feel watched and monitored full time. His later works attempt to recover private space by exploring subversive techniques of the body and language. Following Foucault, pragmatists like Richard Shusterman and Richard Rorty have also developed very rich approaches to this project, extending it deeper into the literary and somatic dimensions of self-stylizing. Yet, for a debate centered on the re-creation of the vision of the self, these discussions have yet to fully engage—even while they set the conditions for this engagement with—issues of posthuman technologies, such as AI, robotics, and genetic engineering. These certainly will constitute the primary engine of public institutional surveillance in the years to come. With this surveillance, the two spheres of private self-fashioning and public institutions will continue to evolve in relation to one another. As they do so, democratic society will change considerably. Perhaps Rorty's own normative and linguistic ideal of conversational maintenance may provide something of a democratic limit case on any future posthuman self-fashioning.     

Excessive self-focused attention and defensiveness among psychiatric patients: a vicious cycle?

The contribution of defensive coping to the phenomenon of excessive self-focused attention was studied in 20 depressed or anxious psychiatric outpatients comprising the negative affect group, 20 patients with psychotic disorders, and a control group of 21 patients of an orthopaedic clinic. Self-focused attention was assessed using the Self-reflectiveness and Internal State Awareness subfactors of the Private Self-consciousness Scale. In accordance with other research on self-focused attention, the negative affect group obtained higher scores on the Self-reflectiveness scale than the control group (t39=2.40, p<.03). To examine the relationship between self-focus and defensiveness, Weinberger, Schwartz, and Davidson's approach was employed, using median splits of short forms of the Taylor Manifest Anxiety Scale and the Marlowe-Crowne scale to differentiate among four groups of subjects. The highest self-reflectiveness was found for those participants who were high in both defensiveness and anxiety. This group scored higher than the nondefensive high anxious group (t30= -2.31, p<.03). The heightened self-focused attention might result from automatically instigated states of self-focused attention and paradoxical effects of defensive efforts to avoid self-focus.     

Acute nicotine withdrawal symptoms and anxious responding to bodily sensations: a test of incremental predictive validity among young adult regular smokers

Although previous work has found associations between panic and smoking, little research has investigated potential mechanisms by which smoking may contribute to panic problems. The present investigation evaluated the incremental validity of acute nicotine withdrawal symptoms (elicited by an average of 2 h of nicotine deprivation) relative to negative affectivity, anxiety sensitivity, and nicotine dependence in predicting anxiety responding to 3-min voluntary hyperventilation. The sample consisted of 90 regular smokers (46 females), as defined by smoking 10 cigarettes per day for at least 1 year, recruited through the general community. Consistent with prediction, greater levels of pre-challenge nicotine withdrawal symptoms uniquely predicted post-challenge intensity of panic symptoms and anxiety relative to other established factors. Findings are discussed in the context of how regular smoking may promote panic symptomotology.     

The onset of receding motion captures attention: comment on Franconeri and Simons (2003)

Franconeri & Simons (2003) reported that some but not all types of motion capture attention in a visual search task, ostensibly because some types of motion are behaviorally significant. In the present article, we argue that a more parsimonious explanation of their results is that the onset of motion, but not motion per se, captures attention. This conclusion helps to resolve inconsistencies between the Franconeri and Simons findings and earlier reports from other investigators and is consistent with results that we have recently reported (Abrams & Christ, 2003). The Franconeri and Simons interpretation rests largely on their failure to find attentional capture by one type of motion-simulated receding motion. We report here the results of two experiments that demonstrate that the onset of receding motion does indeed capture attention when the motion is produced using stereo depth cues. As we have argued elsewhere, the capture of attention in displays containing motion appears to be dependent on the onset of the motion, rather than on the mere presence of specific types of motion as suggested by Franconeri and Simons. One possible explanation is that the onset of motion captures attention because it serves as a strong cue to animacy--and the detection of nearby animals can have important consequences for survival.     

Being better by being right: subjective group dynamics and derogation of in-group deviants when generic norms are undermined

The authors predicted that derogation of group deviants depends on the extent to which in-group norms or values are validated or undermined in a social context. In Experiment 1 participants were less tolerant and derogated in-group deviants more when other in-group members opposed the norm. In Experiment 2 participants derogated in-group deviants more than out-group deviants and than noncategorized individuals, but only when normative in-group members lacked uniformity. In Experiment 3 participants derogated in-group deviants more when there was uncertainty about in-group superiority. These results are consistent with previous research on the black sheep effect (J. M. Marques, V. Y. Yzerbyt, & J. -P. Leyens, 1988) and with the model of subjective group dynamics (D. Abrams, J. M. Marques, N. J. Bown, & M. Henson, 2000; J. M. Marques, D. Abrams, D. Paez, & C. Martinez-Taboada, 1998).     

Age-related differences in object- and location-based inhibition of return of attention

Four experiments examined age-related differences in inhibition of return (IOR) of visual attention. Using static stimuli, both young and older adults were slower to detect targets in previously cued objects, showing equivalent IOR. With objects that moved after they had been cued, young adults were slower to detect targets in the cued object (compared with uncued ones), revealing object-based IOR, but older adults were faster to detect targets in such objects, failing to demonstrate object-based IOR. Both age groups were slower to detect targets at the initially cued location (location-based IOR). The results show that age has a differential effect on IOR depending on the frame of reference of the inhibition: Inhibition for objects breaks down with age, but that for location does not. This pattern of results is consistent with the view that there are specific inhibitory deficits in old age.     

When to intervene and take a stand: Evaluating bystander roles in intergroup name-calling contexts

Children (n = 121, M = 9.86 years, SD = 0.64) and adolescents (n = 101, M = 12.84 years, SD = 0.69) evaluated proactive and passive bystander behaviour to intergroup name-calling (N = 222, 54% female). Scenarios depicted ingroup perpetrators and outgroup victims who were from a stigmatized group (ethnicity) or a non-stigmatized group (school affiliation), with bystanders depicted as being proactive (intervening to help) or passive (failing to challenge the aggression), counter to their own group's norm. Children and adolescents personally evaluated proactive bystanders more favourably than passive bystanders. However, adolescents, more than children, expected their peers to be more positive about proactive bystanders than passive bystanders in the stigmatized context. Results are discussed in terms of the complexities of bystander decisions and implications for anti-bullying interventions.
