Novel stimuli reliably attract attention, suggesting that novelty may disrupt performance when it is task-irrelevant. However, under certain circumstances novel stimuli can also elicit a general alerting response having beneficial effects on performance. In a series of experiments we investigated whether different aspects of novelty – stimulus novelty, contextual novelty, surprise, deviance, and relative complexity – lead to distraction or facilitation. We used a version of the visual oddball paradigm in which participants responded to an occasional auditory target. Participants responded faster to this auditory target when it occurred during the presentation of novel visual stimuli than of standard stimuli, especially at SOAs of 0 and 200 ms (Experiment 1). Facilitation was absent for both infrequent simple deviants and frequent complex images (Experiment 2). However, repeated complex deviant images did facilitate responses to the auditory target at the 200 ms SOA (Experiment 3). These findings suggest that task-irrelevant deviant visual stimuli can facilitate responses to an unrelated auditory target in a short 0–200 millisecond time-window after presentation. This only occurs when the deviant stimuli are complex relative to standard stimuli. We link our findings to the novelty P3, which is generated under the same circumstances, and to the adaptive gain theory of the locus coeruleus–norepinephrine system (Aston-Jones and Cohen, 2005), which may explain the timing of the effects.  相似文献

Managing collective action issues such as pandemics and climate change requires major social and behavioral change. Dominant approaches to addressing these issues center around information provision and financial incentives to shift behavior, yet, these approaches are rarely effective without integrating insights from psychological research on motivation. By accurately characterizing human motives, social scientists can identify when and why individuals engage, and facilitate behavior change and public engagement. Here, we use the core social motives model to sort social psychological theories into five fundamental social motives: to Belong, Understand, Control, self-Enhance, and Trust. We explain how each motive can improve or worsen collective action issues, and how this framework can be further developed towards a comprehensive social psychological perspective to collective action issues.  相似文献

The present research expands on the relationship between subclinical paraphilia and Big Five and Dark Triad personality traits in an online sample of 585 adults. In this sample, sexually deviant courtship behaviors such as exhibitionism and voyeurism were related to high levels of narcissism while transvestism related to greater openness to experience. Further, there were gender differences in the relationship between sadomasochism and personality with sadomasochism reflecting greater openness in men and Machiavellianism in women. These findings suggest that deviant sexual behaviors represent both a degree of antisocial personality functioning and a degree of personal openness that depends on the specific behavior being examined and that more research is needed in this area.  相似文献

PurposeWe previously introduced theStuttering Anticipation Scale (SAS; Jackson, E. S., Gerlach, H., Rodgers, N. H., & Zebrowski, P. M. (2018). My Client Knows That He’s About to Stutter: How Can We Address Stuttering Anticipation during Therapy with Young People Who Stutter? Seminars in Speech and Language, 39, 356–370) – a non-standardized self-report measure for children, teens, and adults who stutter (CWS, TWS, AWS) that quantifies how often they engage in 25 commonly reported action responses to anticipation. The purpose of this study was to leverage the SAS to explore the factor structure of action responses to stuttering anticipation.MethodsA total of 121 people who stutter completed the SAS online (27 CWS, 40 TWS, 54 AWS). We used exploratory factor analysis (EFA) to determine the underlying latent variables within the 25 SAS items that characterize how people who stutter respond to anticipation.ResultsA three-factor model was most appropriate for the data with regard to factor loadings and other model fit indices. The three factors were named: avoidance (17 items), physical change (4 items), and approach (4 items).ConclusionUnderstanding these three types of action responses to anticipation can help guide clinical decision-making by providing a novel framework for clinicians and their clients who stutter to discuss how the client tends to respond to anticipation, and explore ways to facilitate productive responses to anticipation.  相似文献

Everyday function is compromised by mild cognitive changes in aging. These changes predict risk for future decline and dementia but remain poorly characterized, largely due to a scarcity of sensitive, objective measures.Twenty-seven younger adults and 25 non-demented older adults completed the Naturalistic Action Test (NAT), a performance-based measure of everyday action involving simple and complex tasks. Performance was coded for overt errors and subtle inefficiencies. Participants also completed self-report functional measures and cognitive tests. Mixed ANOVAs revealed that older adults made more subtle NAT errors with high task demands; groups did not differ in overt errors. Correlations did not reveal significant relations between self-report and NAT errors, but NAT performance was correlated with learning and recall.The NAT provides a promising tool for detecting subtle age-related changes and examining decline across levels of impairment. Self-report may lack sensitivity to subtle changes, and episodic memory changes underlie early functional disruption.  相似文献

The anterior cingulate cortex (ACC) is believed to be involved in the executive control of actions, such as in monitoring conflicting response demands, detecting errors, and evaluating the emotional significance of events. In this study, participants performed a task in which evaluative feedback was delayed, so that it was irrelevant to immediate response control but retained its emotional value as a performance indicator. We found that a medial frontal feedback-related negativity similar to the error-related negativity (ERN) tracked affective response to the feedback and predicted subsequent performance. Source analysis of the feedback-related negativity and ERN revealed a common dorsomedial ACC source and a rostromedial ACC source specific to the ERN. The oscillatory nature of these sources provides further evidence that the ERN reflects ongoing theta activity generated in the mediofrontal regions. These results suggest that action regulation by the cingulate gyrus may require the entrainment of multiple structures of the Papez corticolimbic circuit.  相似文献

‘We are humans not robots!’ This protest slogan denounces a working reality in which employees perceive that they are reduced to a mere tool or instrument at the service of the organization. Such an experience refers to organizational dehumanization. Researchers have recently indicated that organizational dehumanization may shape employee work behaviours. However, why, and for whom, organizational dehumanization leads to maladaptive work behaviours remains unclear in this literature. Drawing upon social exchange theory, we first propose that employees who experience organizational dehumanization engage in a reciprocity process by first developing thoughts of revenge that, in turn, materialize into more organizational deviance. We further argue that compliance buffers the indirect effect of organizational dehumanization on deviant behaviours via thoughts of revenge. Overall, the combined results of two experimental studies, a cross-sectional study and two three-wave studies provide strong evidence for our hypothesized relationships. Our research suggests that when experiencing organizational dehumanization, compliant employees are less likely to engage in a homeomorphic reciprocity in the exchange relationship with their organization.  相似文献

The association between child psychopathology and reversals in family hierarchies (where the child is seen as equal or higher in the hierarchy than the parental figures) were examined with the Madanes Family Hierarchy Test on a sample of 177 clinic-referred boys. Madanes' original findings of the association of substance use and deviant family hierarchy were replicated in this younger sample, (age 7 to 12). Boys diagnosed with Conduct Disorder reported significantly more deviant hierarchies while boys diagnosed with Overanxious Disorder reported significantly fewer deviant hierarchies. Follow-up results revealed some instability and lack of informant agreement, but the hierarchy measure was not confounded by age, race, SES, IQ, or parents' marital status.  相似文献

This study investigated whether individualism-collectivism (cultural) differences would account for the observed relationship between ethnic group status and affective responses to and fairness perceptions of affirmative action interventions. Forty-nine international (Latin America and East Asia), 116 minority, and 106 majority participants from a major southwestern university and its community provided fairness and affective response ratings to an affirmative action scenario. Implementation policy and qualification of the recipient were also manipulated. Though ethnicity was related to individualism-collectivism, the latter did not explain any variance in affective response ratings. Minority and international participants reported more positive affect and higher agreement and fairness levels than did majority participants. Participants in the preferential treatment and equally qualified conditions had more favorable responses than those in the reverse-discrimination and less qualified conditions.  相似文献

Observing somebody performing an action has been shown to elicit neuronal activity in the premotor cortex. This paper investigated physiological effect of observing an effortful action at the peripheral level. As Autonomic Nervous System responses reflect central nervous system processes such as movement planning and programming, it was expected that observing an action would elicit a pattern of ANS responses matching those recorded during actual movement. 12 male subjects, ages 23 to 28 years (M = 25.5, SD = 1.9), were selected as they were experienced in weight lifting. They were asked to observe a squat movement followed by returning to the upright position under 3 different conditions: (i) observation of actual movement performed by somebody else, (ii) observation of a video of the subject himself (first-person video), and (iii) observation of a video of somebody else performing the same movement (third-person video). Moreover, each movement was observed when performed at 50% and 90% of each participant's personal best mark (% of the highest weight which could be lifted). Three ANS parameters were continuously recorded: skin resistance, temperature and heart rate. ANS responses varied as a function of movement intensity: autonomic responses recorded during movement observation at 90% were significantly higher and longer than those recorded during movement observation at 50%. Thus, autonomic responses were linked to the amount of observed effort. Conversely, no difference was found among the three conditions of observation. ANS responses from observation of actual movement were shown to resemble those recorded under the two conditions of video observation.  相似文献

Twenty mother-infant dyads (10 boys, 10 girls) were videotaped longitudinally at ages 10, 13, 17, and 21 months during in-home free play and bath sessions. Mothers' and infants' responses to their partners' naturally occurring action and vocal/verbal imitations were described, and relations to infants' imitation rates and vocabularies were examined. Mothers' response rates were consistently high and unrelated to infants' imitation rates. As early as 10 months, infants responded to the great majority of maternal imitations, especially action imitations, often with actions. Infants' return imitations to action matching indicated increasing awareness of being imitated. Infants' responses to mothers' vocal/verbal imitation were associated with their later vocabulary levels. Children who would be more lexically advanced at 17 and/or 21 months provided more social responses at 10 months, more socially responsive actions and return verbal imitations at 13 months, and more non-imitative socially responsive words at 17 and 21 months.  相似文献

Conflicting predictions were derived from social exchange theory about the role of social attraction and the reciprocity norm on mutual self-disclosure in dyadic relationships. Sixty-six female subjects were exposed to one of three levels of disclosure input: conventional-low disclosure, conventional-high disclosure, or devianthigh disclosure. In support of the reciprocity norm prediction, willingness to disclose personal information was a positive function of the amount of disclosure input from another person, regardless of the degree of liking for the initial discloser.  相似文献

Previous studies have focused on the seriousness of the offenses but have neglected the offenders. This analysis used a Bogardus-type social distance scale of 23 deviant roles using a sample of 524 respondents who indicated decided preferences for some types of deviant offenders over others. It was concluded that individuals occupying various roles such as judges, defenders, juries, and so on may feel great social distance toward certain types of offenders and may act differentially toward them.  相似文献

ABSTRACT

This study investigated eating and deviant behaviors in bodybuilders according to their competitive engagement. Semi-structured interviews were conducted with 16 bodybuilders of different skill levels. Results revealed that dietary strategies and deviations (e.g., disordered eating, doping use, addictive training) developed with competitive commitment. Bodybuilders who intend to engage in competition are in a critical period for the development of deviant behaviors, in relation with increasing drive for muscularity and performance, and coaching pressure. These findings extend the existing literature on deviant behaviors in bodybuilding by providing better insight in the dynamics of development of disordered eating and associated behaviors.  相似文献

In two experiments on very young children's response to the orientation of pictures and objects, 18-, 24- and 30-month-old children showed no preference for upright pictures over inverted ones. More importantly, we found that children in all three age groups were equally accurate and equally fast at identifying depicted objects regardless of orientation. These studies further established that young children's insensitivity to picture orientation does not extend to objects. These results, in combination with the earlier ones, indicate that only gradually do young children come to share the picture orientation preference of adults and older children and that their adoption of the orientation convention is not based on changes in their ability to process upright and inverted images.  相似文献

Recent investigations into how action affects perception have revealed an interesting “action effect”—that is, simply acting upon an object enhances its processing in subsequent tasks. The previous studies, however, relied only on manual responses, allowing an alternative stimulus-response binding account of the effect. The current study examined whether the action effect occurs in the presence of changes in response modalities. In Experiment 1, participants completed a modified action effect paradigm, in which they first produced an arbitrary manual response to a shape and then performed a visual search task in which the previous shape was either a valid or invalid cue—responding with a manual or saccadic response. In line with previous studies, the visual search was faster when the shape was a valid cue but only if the shape had been acted upon. Critically, this action effect emerged similarly in both the manual and ocular response conditions. This cross-modality action effect was successfully replicated in Experiment 2, and analysis of eye movement trajectories further revealed similar action effect patterns on direction and numerosity. These results rule out the stimulus-response binding account of the action effect and suggest that it indeed occurs at an attentional level.  相似文献
