Interrelationships between spider fear associations,attentional disengagement and self-reported fear: A preliminary test of a dual-systems model

Recent conceptualisations of anxiety posit that equivocal findings related to the time-course of disengaging from threat-relevant stimuli may be attributable to individual differences in associative and rule-based processing. The current study was designed to test the hypothesis that strength of spider-fear associations would indirectly predict reported spider fear via impaired disengagement. One hundred and thirty-one undergraduate volunteer participants completed the Go/No-go Association Task, a visual search task, and self-report spider fear questionnaires. Stronger spider-fear associations were associated with reduced disengagement accuracy, whereas higher levels of reported spider fear were related to faster engagement with and disengagement from spiders. Bootstrapping multiple mediation analyses demonstrated that stronger-spider fear associations evidenced an indirect relationship with reported spider fear via reduced disengagement accuracy, highlighting the importance of fine-grained analyses of different aspects of cognitive bias. Results are discussed in terms of cognitive models of anxiety.     

On Nachträglichkeit: The modernity of an old concept1

Nachträglichkeit provides the memory, not the event, with traumatic signifi cance and signifi es a circular complementarity of both directions of time. Conceived by Freud as early as 1895 in the Project for a scientifi c psychology, the concept remains in his work without offi cial status but through its character of biphasic development and latency indispensable for understanding temporal connections and psychic causality. As an implicit principle it is linked with the postponement and biphasic onset of sexual life … and retains its sometimes hidden importance until the late Moses study. Temporarily virtually forgotten, it was recalled to memory by Lacan in 1953. Translations into French as après‐coup and into English as ‘deferred action’ emphasized the two vectors (retroactivity and after‐effect) separately which are united in the substantive form coined by Freud. Unnoticed, it played a part in many aspects of clinical practice, especially in Winnicott's Fear of breakdown and the subsequent (nachträglich) working through of unconscious infantile and transgenerational confl icts. The author uses a clinical illustration to elucidate the belated understanding of the striving for non‐existence in Winnicott's sense. Wolfgang Loch extended Freud's concept of Nachträglichkeit in a constructivist way, advocating an art of interpretation as an innovative enterprise through which connections are not only unmasked but also created, constituted by subsequent (nachträglich) reinterpretation of a subjective past. Very briefl y the author refers to the interdisciplinary reception of the concept of Nachträglichkeit, especially in cultural studies.     

Effect of exposure to lithium-paired or amphetamine-paired saccharin solution on open arm avoidance in an elevated plus maze

Recent evidence suggests that drug-induced conditioned taste avoidance may be mediated by conditioned fear (e.g., Parker, 2003). The experiments reported here evaluated the effect of exposure to a drug-paired flavor on open arm exploration in an elevated plus maze (EPM), a measure of fear. When rats were tested on a familiar (trial 2) EPM, but not on a novel (trial 1) EPM, prior exposure to a lithium-paired saccharin solution enhanced open arm activity relative to saline-paired saccharin. On the other hand, when rats were exposed to lithium-paired saccharin during plus maze exposure, they displayed suppressed open arm activity relative to unpaired controls when tested in a familiar maze. The pattern of results was specific to the conditional affective properties of the taste, because exposure to unconditional sickness produced by administration of lithium, and unconditionally unpalatable quinine solution did not produce this pattern. These results were interpreted in terms of the opponent process model of motivation; that is, exposure to a lithium-paired flavor elicits conditioned fear which is immediately followed by conditioned relief when the exposure is terminated. On the other hand, exposure to an amphetamine-paired flavor either before or during EPM testing enhanced open arm exploration. Since the strength of taste avoidance did not differ among amphetamine and lithium conditioned rats, these results provide further evidence that the nature of a saccharin-lithium association differs from that of a saccharin-amphetamine association.     

The callousness pathway to severe violent delinquency

Children and adolescents who exhibit a callous interpersonal style seem to be at risk for developing severe forms of violent behavior. Theoretical models suggest that children with low levels of temperamental fearfulness may be at increased risk for developing callous traits because they are relatively unaffected by punishment. This study examines hypotheses about the callousness pathway to severe violent delinquency in a cross‐sectional sample of 169 (97=males, 72=females) adjudicated adolescents. Structural equation modeling is used to test mediation models regarding the relation between temperamental fear, punishment concern, callousness, and severe violent delinquency. The findings of the study indicate that the relation between low levels of temperamental fear and increased callousness is mediated by a lack of concern about being punished for aggressive acts. Although low levels of fear and punishment concern were both related to increased levels of severe violent delinquency, increased levels of callousness mediated these relations. All findings remained significant after controlling for the potential confounds of gender, race, and social desirability. The results provide a heuristic for understanding the callousness pathway to severe violent behavior in youth. However, longitudinal investigations replicating these results are necessary before firm conclusions can be drawn. Aggr. Behav. 32:590–598, 2006. © 2006 Wiley‐Liss, Inc.     

The effect of varying danger controllability on attention to threat messages

The objective of this study is to determine whether attention toward fear messages is affected by variation in the controllability of the associated danger. There is no consensus regarding the effectiveness of fear appeals in driving adaptive behaviour, and it may be the case that threat messages fail to capture attention if the associated danger is not explicitly controllable. One hundred and sixty undergraduate university students completed a computer task that involved exposure to threat cues signalling a danger (money loss). In high control blocks, attending to threat cues provided a high chance of avoiding the danger, whereas in low control blocks, attending to threat cues provided little chance of avoiding the danger. Attentional capture by threat was measured. A mixed-design analysis of variance showed there was greater attentional capture by threat cues in high control blocks compared with low control blocks. This effect was observed with a short stimulus exposure duration and was magnified with a long exposure duration. Fear appeals could capture attention to a greater degree if the danger related to the threat message was communicated as being controllable. This has significant practical implications for the implementation of fear appeals.     

The effect of fear‐inducing content on memory for advertisements and on retroactive and proactive interference of programme information

The current study focused on whether fear‐inducing content in television advertisements leads to better memory for the advertisement but also impairs memory for programme information that either precedes the advertisements (retroactive interference) or that follows the advertisements (proactive interference). Fifty‐four participants (48 female) aged 18 to 55 watched a programme that had an advertisement break in the centre. This consisted of 6 advertisements with either fear‐inducing or nonfear‐inducing content. Participants were tested on their recall and recognition of the advertisement information as well as their recall of the first half and second half of the programme. The results indicated that fear‐inducing advertisements were better recalled than those that elicited no fear, and there was also evidence of proactive interference from fear‐inducing advertisements on programme recall. Limitations and implications of the study are discussed.     

On the Conceptual Overlap between the Fluency Contamination Effect in Divergent Thinking Scores and the Chance View on Scientific Creativity

The equal odds baseline is a parsimonious model that describes the relationship between quantity and quality of output in scientific creativity. Specifically, it is posited that quality is a linear function of quantity, and therefore, strong positive correlations between these two variables are expected. Strong positive correlations also play a crucial role in a recurring issue in divergent thinking research: the fluency contamination effect. This effect refers to the problem that any other summative scoring of divergent thinking tests such as the number of original responses (i.e., quality of responses) is confounded by fluency (i.e., quantity of responses). The current work sheds further light into the conceptual overlap between the equal odds baseline, and the fluency contamination effect by demonstrating that a recent formalization of the fluency contamination effect can be used to derive the equal odds baseline. This result is then utilized within a structural equation modeling approach with simulated datasets to thoroughly examine the equal odds baseline. The findings of the structural equation modeling approach are discussed with respect to their potential to better understand the relationship between quantity and quality of productions in creativity research.     

Online Hate and Zeitgeist of Fear: A Five-Country Longitudinal Analysis of Hate Exposure and Fear of Terrorism After the Paris Terrorist Attacks in 2015

Acts of terror lead to both a rise of an extended sense of fear that goes beyond the physical location of the attacks and to increased expressions of online hate. In this longitudinal study, we analyzed dynamics between the exposure to online hate and the fear of terrorism after the Paris attacks in November 13, 2015. We hypothesized that exposure to online hate is connected to a perceived Zeitgeist of fear (i.e., collective fear). In turn, the perceived Zeitgeist of fear is related to higher personal fear of terrorism both immediately after the attacks and a year later. Hypotheses were tested using path modeling and panel data (N = 2325) from Norway, Finland, Spain, France, and the United States a few weeks after the Paris attacks in November 2015 and again a year later in January 2017. With the exception of Norway, exposure to online hate had a positive association with the perceived Zeitgeist of fear in all our samples. The Zeitgeist of fear was correlated with higher personal fear of terrorism immediately after the attacks and one year later. We conclude that online hate content can contribute to the extended sense of fear after the terrorist attacks by skewing perceptions of social climate.     

普萘洛尔修复即刻消退产生的二次创伤

恐惧消退能力的受损是创伤后应激障碍(posttraumatic stress disorder, PTSD)的标志之一。以往的研究表明, 相较于延迟消退, 恐惧获得后短时间内进行的消退训练不能形成长时程的消退记忆, 这一现象被称为即刻消退缺损。然而, 目前并不清楚这种缺损是一次性的, 还是会继续影响其后的重消退。实验1中, 大鼠在恐惧习得后1小时(即刻消退)或24小时(延迟消退)开始进行消退训练, 24小时后进行重消退, 再24小时后进行消退记忆的测试。结果显示, 与延迟消退相比, 即刻消退效果缺损, 并引起第二天的重消退也出现效果缺损。实验2中, 恐惧获得后立即给予大鼠盐水或β-肾上腺素受体阻断剂普萘洛尔(10 mg/kg, i.p.), 然后测试即刻消退和重消退的效果。结果显示, 普萘洛尔虽没有阻止即刻消退的缺损, 但避免了重消退出现缺损。总之, 严重创伤后的即刻消退不但无法有效抑制恐惧反应, 还可能造成二次创伤, 会损害恐惧消退能力, 而普萘洛尔可修复即刻消退引起的重消退缺损。这些结果将有助于我们加深对PTSD病理机制和早期干预后果的认识。
