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.     

Self-presentation and drive in social facilitation

Social facilitation refers to cases in which the presence of others increases the probability of certain responses on the part of an independently operating individual. Drive theory attributes these effects to an unconscious facilitation of dominant responses, as defined by Hull-Spence learning theory. Self-presentation explanations posit changes in motivation and cognitive strategies that result from an increased concern with favorable private and public images. The present paper reviews evidence and presents an experiment indicating both points of view are valid, but that neither perspective by itself can account for all relevant data.     

Distraction,attentional conflict,and drivelike behavior

Two studies provide evidence supporting a distraction-conflict view of social facilitation effects. Study 1 demonstrated that presence of an audience produced drivelike effects on the latency and vigor of a motor response. This effect, however, only occurred when attending to the audience caused attentional conflict. Study 2 demonstrated that in a two-task setting, attentional conflict, resulting from having to choose which task to work on, led to poorer performance on a complex copying task (p < .01, one tailed) and a larger percentage of dominant responses on J. L. Cohen and J. H. Davis' (Journal of Personality and Social Psychology, 1973, 27, 74–85) hidden word task (p < .04, one tailed), relative to a yoked control. Study 2 is consistent with earlier reports that choice heightens drivelike effects, while Study 1 indicates that attentional conflict contributes to social facilitation phenomena.     

类别注意控制定势在注意捕获中的加工机制

注意捕获是指注意定向的过程中刺激不自觉地捕获注意的现象。在复杂的视觉搜索任务中,类别注意控制定势(cACS)能够帮助我们将注意引导到与目标定义类别匹配的刺激上,并对其进行优先加工。探讨cACS在注意捕获中的加工机制,不仅能够扩展注意捕获领域的理论研究,还能对实际生活提供指导。通过文献梳理,从cACS的作用阶段、cACS的加工强度及cACS作用时的激活脑区三个方面总结了注意捕获中的cACS的加工机制。未来研究可以就抑制分心物的ACS、不同类型的cACS加工差异和人工类别ACS加工过程等进行探讨。     

Attentional interference by threat and post-traumatic stress disorder: The role of thought control strategies

Attentional interference by threat is associated with PTSD, but the mechanisms of this relationship remain unclear. Attentional interference might be related to increased use of maladaptive thought control strategies, such as suppressing unwanted thoughts (thought suppression) or replacing threatening thoughts with everyday concerns (worry), which increase PTSD risk. Conversely, attentional interference might be associated with reduced use of adaptive strategies, such as talking about threatening thoughts (social control), which decrease PTSD risk. This study tested if thought control strategies mediate the relationship between attentional interference and PTSD. Sixty-one male Vietnam-era veterans completed measures of PTSD symptoms and thought control strategies. Participants also completed a Visual Search Task measuring attentional interference, which required participants to identify a target letter string among a group of threat or neutral words. Attentional interference by threat was related to PTSD symptoms, and mediation analyses revealed significant indirect effects of attentional interference through thought suppression and worry. Attentional interference was related to re-experiencing and avoidance, but not hyperarousal, symptom clusters. Thought suppression was a unique mediator for re-experiencing, whereas thought suppression and worry both mediated the relationship with avoidance. These results offer evidence for maladaptive thought control strategies as a mechanism linking attentional biases for threat to PTSD.     

Attention network test — The impact of social information on executive control,alerting and orienting

According to the attention network approach, attention is best understood in terms of three functionally and neuroanatomically distinct networks — alerting, orienting, and executive attention. An important question is whether social information influences the efficiency of these networks. Using the same structure as the Attentional Network Test (ANT), we developed a variant of this test to examine attentional effects in response to stimuli with and without social-cognitive content. Fish, drawings or photographs of faces looking to the left or right were used as target stimuli. Results collected from twenty-four university students showed that photographs of faces positively affected attentional orienting and executive control, whereas reduced the efficiency of alerting, as compared to both face drawings and fish. These results support the status of human faces as a special class of visual stimuli for the human attentional systems.     

Effortful control, executive attention, and emotional regulation in 7–10-year-old children

In this study, self-regulation was investigated in 7- to 10-year-old children using three different measures: (1) parent and child report questionnaires measuring temperamental effortful control, (2) a conflict task assessing efficiency of executive attention, and (3) the mistaken gift paradigm assessing social smiling in response to an undesirable gift. Both efficiency in executive attention and smiling to the undesired gift increased over age. Executive attention was related to both parent-reported temperamental effortful control and smiling, suggesting links between attentional capacities, broad temperament measures, and social situations requiring attentional control.     

Limits of control: The effects of uncontrollability experiences on the efficiency of attentional control

Two experiments were conducted to explore the effects of experiencing uncontrollability on the efficiency of attentional control. The experience of uncontrollability was induced either by unsolvable tasks (Experiment 1) or by tasks in which non-contingent feedback was provided (Experiment 2). A version of the Attentional Network Test-Interactions with an additional measure of vigilance (ANTI-V) was used to evaluate the efficiency of the attentional networks (i.e., alerting, orienting, and executive). Results of both experiments revealed a decreased efficiency of executive attention in participants who experienced stable control deprivation but no negative effects in participants who were able to restore their sense of previously deprived control. Additionally, when participants were asked to perform unsolvable tasks and did not receive feedback (Experiment 1), detrimental effects on the orienting network and vigilance were observed. The motivational and cognitive mechanisms underlying the effects of various uncontrollability experiences on conflict resolution and attentional control are discussed.     

Cortisol,stress, and attentional bias toward threat

Abstract

Attentional bias toward threatening stimuli is a central characteristic of anxiety and acute stress. Recent small-scale studies have provided divergent perspectives on the association between the stress hormone cortisol and attentional bias toward threat cues. In a larger sample size than previous studies, we examined this association by investigating the impact of cortisol on attentional bias in two studies using a psychological stressor (N=35) and a physical stressor (N=65), respectively. Attentional bias and salivary cortisol were measured prior to and following the administration of a stressful task designed to increase cortisol levels. Results across these studies were equivocal relative to the association between baseline cortisol and baseline attentional bias. In addition, the association between acute change in cortisol and change in attentional bias appeared to differ as a function of the presence or absence of psychological stress. There was a trend toward a stronger negative association between acute cortisol change and attentional bias change among women relative to men. These results imply that the association between cortisol and attentional bias may be moderated by additional factors, such as gender or presence of stress.     

Temperament, anxiety, and attentional control

To regulate attention has been a significant component of individual differences in temperament, and other research supported a relation between measures of attentional control and anxiety, i.e., high scores on trait anxiety were correlated with inability to regulate attention in response to the environment, so enhanced attentional control may interact with dimensions of temperament to modify the effects of generalized anxiety. To test this hypothesis, 69 undergraduates completed the Revised Dimensions of Temperament Survey, the Burns Anxiety Scale, and the Derryberry and Reed measure of Attentional Control. Analysis suggested attentional control may be a significant factor in modifying reported anxiety. Further research is warranted, given the present small sample tested with numerous measures.     

Automatic attention to stimuli signalling chances and dangers: Moderating effects of positive and negative goal and action contexts

Current research on automatic attention allocation focuses on the questions whether there is an asymmetry in attentional biases towards negative and positive stimuli and whether these attentional biases are influenced by situational variables. In an experiment with N = 48 participants, automatic allocation of attention to chance and danger stimuli was investigated. Attentional capture was generally larger for chance stimuli than for danger stimuli. Additionally, attentional bias was influenced by the outcome focus of the actual goal orientation. Results revealed an incongruence effect of goal orientation on attentional biases: Attentional capture for the chance and danger stimuli was comparatively stronger when an outcome focus of opposite valence had been induced.     

Attentional dysfunction, social perception, and social competence: what is the nature of the relationship?

The aim of this study was to examine the nature of the relationship between attentional dysfunction and social competence deficits in patients with schizophrenia. Attentional functioning, social perception, and social competence were assessed in 56 inpatients. Measures of vigilance and span of apprehension were administered to assess attentional functioning. Social perception was assessed with an audiovisual measure of affect recognition. Social competence was rated from a role-play task. Span of apprehension and auditory vigilance emerged as specific predictors of social competence. Affect recognition was tested as a mediator and a moderator of the relationship between attentional dysfunction and social competence. Affect recognition was found to moderate the relationship between span of apprehension and social competence.     

Emotion regulation strategy selection in daily life: The role of social context and goals

Recent studies have begun to document the diversity of ways people regulate their emotions. However, one unanswered question is why people regulate their emotions as they do in everyday life. In the present research, we examined how social context and goals influence strategy selection in daily high points and low points. As expected, suppression was particularly tied to social features of context: it was used more when others were present, especially non-close partners, and when people had instrumental goals, especially more interpersonal ones (e.g., avoid conflict). Distraction and reappraisal were used more when regulating for hedonic reasons (e.g., to feel better), but these strategies were also linked to certain instrumental goals (e.g., getting work done). When contra-hedonic regulation occurred, it primarily took the form of dampening positive emotion during high points. Suppression was more likely to be used for contra-hedonic regulation, whereas reappraisal and distraction were used more for pro-hedonic regulation. Overall, these findings highlight the social nature of emotion regulation and underscore the importance of examining regulation in both positive and negative contexts.     

社交焦虑注意偏向的动态变化

注意偏向是社交焦虑障碍(Social Anxiety Disorder, SAD)个体症状维持的重要因素, 其中注意警觉、注意回避、注意脱离困难三种注意模式得到了研究者最广泛的研究与讨论。随着研究深入, 有研究者提出SAD个体的注意模式不是单一、静态模式, 更有可能在不同注意模式间切换, 表现为动态的过程。目前, 依据相关研究结果和理论假设, 证据均指向SAD个体的注意偏向具有随着焦虑水平提高和注意控制能力受损而动态变化的倾向, 从注意警觉过渡到注意回避与注意脱离困难均如此。此观点还需研究进一步证实, 并且基于研究结果提出更具有针对性的干预方式。     

Anxiety and cognitive performance: attentional control theory

Attentional control theory is an approach to anxiety and cognition representing a major development of Eysenck and Calvo's (1992) processing efficiency theory. It is assumed that anxiety impairs efficient functioning of the goal-directed attentional system and increases the extent to which processing is influenced by the stimulus-driven attentional system. In addition to decreasing attentional control, anxiety increases attention to threat-related stimuli. Adverse effects of anxiety on processing efficiency depend on two central executive functions involving attentional control: inhibition and shifting. However, anxiety may not impair performance effectiveness (quality of performance) when it leads to the use of compensatory strategies (e.g., enhanced effort; increased use of processing resources). Directions for future research are discussed.     

Relationships between the Test of Attentional and Interpersonal Style and psychiatric subclassification

Examined the ability of a self-report measure of attentional and interpersonal characteristics to discriminate between groups of psychiatric patients and normal controls. Seventy-eight psychiatric patients and 30 nonpsychiatric medical inpatients completed the Test of Attentional and Interpersonal Style (TAIS). Discriminant analyses of TAIS scores showed that: (a) psychiatric patients in comparison with normal controls described themselves as more overloaded by external and internal stimuli and as less effective in narrowing their attentional focus to task-relevant stimuli; (b) good premorbid schizophrenics appeared more externally overloaded and less able to narrow attentional focus than poor premorbid schizophrenics; and (c) psychotics and neurotics described themselves as more introverted and less pleasant in social encounters, while individuals diagnosed as character or personality disorders tended to be more extroverted and impulsive. The results were compatible with past experimental work and clinical reports identifying attentional and interpersonal differences among psychiatric subgroups.     

Attention for emotional facial expressions in dysphoria: an eye-movement registration study

Former research demonstrated that depression is associated with dysfunctional attentional processing of emotional information. Most studies examined this bias by registration of response latencies. The present study employed an ecologically valid measurement of attentive processing, using eye-movement registration. Dysphoric and non-dysphoric participants viewed slides presenting sad, angry, happy and neutral facial expressions. For each type of expression, three components of visual attention were analysed: the relative fixation frequency, fixation time and glance duration. Attentional biases were also investigated for inverted facial expressions to ensure that they were not related to eye-catching facial features. Results indicated that non-dysphoric individuals were characterised by longer fixating and dwelling on happy faces. Dysphoric individuals demonstrated a longer dwelling on sad and neutral faces. These results were not found for inverted facial expressions. The present findings are in line with the assumption that depression is associated with a prolonged attentional elaboration on negative information.     

Organizational and spatial dynamics of attentional focusing in hierarchically structured objects

Is the focusing of visual attention object-based, space-based, both, or neither? Attentional focusing latencies in hierarchically structured compound-letter objects were examined, orthogonally manipulating global size (larger vs. smaller) and organizational complexity (two-level structure vs. three-level structure). In a dynamic focusing task, participants successively identified the global and local letters in the same trial. Overall response latencies were generally longer for larger versus smaller global objects and for three-level versus two-level object structure, indicating that attentional focusing time increases both with the magnitude of change in attentional aperture size and with the number of traversed levels of object structure. Additional experiments showed that this pattern is unique to tasks that require dynamic attentional focusing. Taken together, the results support a hierarchical object-based-spatial model of attentional focusing.     

Explanations of social facilitation: A review

A review is made of the behavioral effects of the presence of a conspecific. A large number of behavior changes are discussed, in three groups. First, there are effects of the presence of others on the level of arousal or alertness; under predictable conditions the presence of a conspecific will increase arousal level. Second, there are effects on attentional processes. For a variety of reasons, conspecifics require attending. Third, the presence of others can induce a social valuation on particular behaviors, so that they become positively or negatively valued. For each of these three groups, a number of possible mechanisms are elaborated, and a number of mediating variables are discussed. Further, an attempt is made to link each of these behavioral effects to human and nonhuman social relations, to show how they function in social organization. Even the “minimal” social setting, one person with another, can have effects ranging from physiological changes to inducing the “presence” of the social power structures or social organization of a social group. Lastly, future directions for research in this area are suggested, and problems with the present research are examined. Foremost here is the use of implied audiences, mirrors, and real audiences, as manipulations of social conditions. It is argued that these will result in different effects, and some evidence for this is reviewed.     

The protective role of long-term meditation on the decline of the executive component of attention in aging: a preliminary cross-sectional study

Life expectancy is constantly increasing. However, a longer life not always corresponds to a healthier life. Indeed, even normal aging is associated with a decline in different cognitive functions. It has been proposed that a central mechanism that could contribute to this widespread cognitive decline is an ineffective inhibitory attentional control. Meditation, to the other hand, has been associated, in young adults, to enhancement of several attentional processes. Nevertheless, attention is not a unitary construct. An influent model proposed the distinction of three subsystems: the alerting (the ability to reach and maintain a vigilance state), the orienting (the capacity of focusing attention on a subset of stimuli), and the conflict resolution or executive component (the ability to resolve conflict or allocate limited resources between competing stimuli). Here, we investigated, employing the Attentional Network Task (ANT), the specific impact of age on these three subcomponents, and the protective role of long-term meditation testing a group of older adults naïve to meditation, a group of age-matched adults with long-term practice of meditation, and a group of young adults with no previous meditation experience. We reported a specific decline of the efficiency of the executive component in elderly that was not observed in age-matched meditators. Our results are encouraging for the investigation of the potential beneficial impact of meditation on other cognitive processes that decline in aging such as memory. Moreover, they could inform geriatric healthcare prevention and intervention strategies, proposing a new approach for cognitive remediation in elderly populations.
