The effects of social comparison,emotion induction,and parent vaccination status on parental intentions for COVID-19 vaccine uptake in children

Parental vaccine hesitancy—delays in vaccine uptake for children—is a significant public health concern. Using an online adult sample of U.S. parents (N = 183), the current research experimentally examined how exposure to cautious or risky social comparison models on social media (in terms of their COVID-19 beliefs and behaviors) influenced parental intentions to vaccinate their children against COVID-19 in the early stages of the pandemic. Additionally, we examined whether the influence of social comparison models was moderated by emotional state (fear or contentment) and parental vaccination status. Overall, we found that parents exposed to cautious (vs. risky) comparison models and vaccinated (vs. unvaccinated) parents reported greater vaccine intentions for their children. We further found that vaccination intentions were highest among unvaccinated parents after exposure to cautious (vs. risky) comparison models, whereas intentions were highest among vaccinated parents after exposure to risky (vs. cautious) comparison models (but only when induced to feel content). Overall, our findings highlight the importance of understanding the additive and interactive impact of psychological and situational factors in shaping parental vaccine hesitancy.     

Specificity of interoceptive fear to panic disorders

It has been argued that fear of interoceptive sensations is a maintaining factor in panic disorders. This study investigated whether interoceptive fears are specific to panic disorders or whether they are a feature of neurosis in general. Twenty-nine panic patients, 28 nonpanicking neurotic controls, and 29 normal controls were compared for their scores on a 14-item questionnaire intended to measure interoceptive fears. Indeed it was found that panic patients scored considerably higher than both control groups, whereas no significant differences emerged between the two control groups. It is concluded that interoceptive fear is diagnostically specific to panic disorders.This study was partly supported by the Dutch Organization for Fundamental Research (ZWO/Psychon., 560-268-001) and was carried out at the unit for clinical behavior therapy at Vijverdal Mental Hospital, Maastricht, The Netherlands.     

Death anxiety among New Zealanders: the predictive role of gender and marital status

The aim of this cross-sectional study was to investigate attitudes of New Zealanders towards death and dying. We administered an online version of Collett–Lester Fear of Death Scale and Concerns About Dying Instrument subscales to a representative sample of the New Zealand population. In total, 1001 people responded to the survey. Women reported more anxiousness concerning their own death (p?=?.001) and dying at a young age (p?>?.001). Women also showed more agreement towards spiritual aspects of dying (p?>?.001). Single female respondents worry more about dying (p =?.02) especially when young (p?=?.003). Single participants (p >?.001) aged 18 and 29 (p?>?.001) reported higher anxiety for Items relating to the death of others especially concerning never being able to communicate with the person again. Our findings show that marital status and gender strongly predict higher levels of death anxiety among New Zealanders. This is probably due to the cultural identity of those sampled.     

风险来源与决策:背信规避现象及人际联结需求的作用

经典的风险决策研究及相关理论模型关注人们如何对以不同概率出现的损益结果进行评价与选择,但很少区分和探究在相同概率和损益值下不同风险来源对决策的影响。事实上,决策情境中的风险既可能源自客观因素,也可能源自人为因素。与相同大小的客观风险相比,人们更规避人为风险,这种现象被称为"背信规避"。本研究采用信任博弈任务,通过最小可接受概率法和决策选择法两种方式探讨风险来源对决策冒险性的影响。结果发现:(1)中国被试存在"背信规避"现象,即对人为风险的规避程度高于客观风险;(2)当恐惧情绪被唤起时,被试对人为风险的规避程度降低,使得背信规避现象消失,甚至出现"反背信规避"倾向;(3)人际联结需求影响背信规避,人为风险下人际联结需求中介了恐惧情绪对决策冒险性的影响。上述结果有助于加深我们对风险来源影响决策的现象及其机制的理解。     

Enduring without avoiding: Pauses and verbal dysfluencies in public speaking fear

Direct measures of overt behavior have been underutilized in speech and other social fear, anxiety, and phobia research. This study demonstrates the usefulness of such variables in the evaluation of public speaking fear. A molecular behavioral assessment methodology was used to examine pauses and verbal dysfluencies of individuals with circumscribed speech fear (n=8) or general social anxiety (n=8), as well as nonanxious control participants (n=16), during an impromptu speech behavior test. Speech fear and generally social anxious individuals paused more often and for a longer duration than the nonanxious group. Results also indicated greater increases in state anxiety during the speech in the circumscribed speech fear sample, relative to the generalized social anxiety and control groups. Taken together with other research, these findings provide evidence that circumscribed speech fear is a meaningful subtype and can be independent of generalized social anxiety. The utility of measuring pausing and verbal dysfluencies in the behavioral assessment of speech fear and other social anxiety and phobia is discussed.     

Ecological assessments of community disorder: Their relationship to fear of crime and theoretical implications

Researchers suggest that fear of crime arises from community disorder, cues in the social and physical environment that are distinct from crime itself. Three ecological methods of measuring community disorder are presented: resident perceptions reported in surveys and on-site observations by trained raters, both aggregated to the street block level, and content analysis of crime- and disorder-related newspaper articles aggregated to the neighborhood level. Each method demonstrated adequate reliability and roughly equal ability to predict subsequent fear of crime among 412 residents of 50 blocks in 50 neighborhoods in Baltimore, MD. Pearson and partial correlations (controlling for sex, race, age, and victimization) were calculated at multiple levels of analysis: individual, individual deviation from block, and community (block/neighborhood). Hierarchical linear models provided comparable results under more stringent conditions. Results linking different measure of disorder with fear, and individual and aggregated demographics with fear inform theories about fear of crime and extend research on the impact of community social and physical disorder. Implications for ecological assessment of community social and physical environments are discussed.

Word priming without awareness: A new approach to circumvent explicit memory contamination

A major methodological limitation arising in the experimental study of implicit memory is that tasks that are characterized as implicit memory tests can be seriously contaminated by the use of covert explicit memory strategies. Given the evidence indicating that brief presentation of words (below the awareness threshold of subjects) can produce semantic priming, we wondered whether rapid visual presentation of primed words might provide an avenue to produce word priming without explicit memory contamination. Normal subjects were tested for word priming on a speeded category membership decision task. Explicit or implicit encoding procedures were used in four different experiments. Results demonstrated that brief presentation of words can indeed offer a means of producing word priming in absence of explicit recognition or recall of the primed words presented during the study phase. They also showed that such priming is equivalent in degree to the priming measured when using either a conventional implicit memory design or an explicit encoding procedure prior to the study of the primes.     

Why Don't People Change? A Psychoanalytic Perspective

From a psychoanalytic perspective, a central reason that people do not easily change is their fear of the dangers that they believe, at some level, change entails. These dangers include relinquishment of infantile wishes and fantasies, anxiety that would be experienced were defenses weakened, guilt, fantasies that change would harm a parental figure or threaten a vital relationship. Other factors that prevent change and maintain the sameness of behavior include defenses, unconscious pathogenic beliefs, devotion and loyalty to early figures, stable internal working models of self, other, and prototypic interactions, and emitting cues that elicit responses from others that confirm these working models. Finally, 1 discuss some selective psychoanalytic research on therapeutic change.     

Contribution of Ventrolateral Prefrontal Cortex to the Acquisition and Extinction of Conditioned Fear in Rats

The ventrolateral, agranular insular portion of prefrontal cortex (PFC) in rats is involved in visceral functions and has been shown to be involved in emotional processes. However, its contribution to aversive learning has not been well defined. Classical fear conditioning has been a powerful tool for illuminating some of the primary neural structures involved in aversive emotional learning. We measured both the acquisition and the extinction of conditioned fear following lesions of the ventrolateral PFC of rats. Lesions reduced fear reactivity to contextual stimuli associated with conditioning without affecting CS acquisition, and had no effect on response extinction. Ventrolateral PFC may normally be involved in the processing of contextual information while not being directly involved in extinction processes within the aversive domain.
