Bayes,time perception,and relativity: The central role of hopelessness

Time judgement and time experience are distinct elements of time perception. It is known that time experience tends to be slow, or dilated, when depressed, but there is less certainty or clarity concerning how depression affects time judgement. Here, we use a Bayesian Prediction Error Minimisation (PEM) framework called ‘distrusting the present’ as an explanatory and predictive model of both aspects of time perception. An interval production task was designed to probe and modulate the relationship between time perception and depression. Results showed that hopelessness, a symptom of severe depression, was associated with the ordering of interval lengths, reduced overall error, and dilated time experience. We propose that ‘distrusting the future’ is accompanied by ‘trusting the present’, leading to the experiences of time dilation when depressed or hopeless. Evidence was also found to support a relative difference model of how hopelessness dilates, and arousal accelerates, the rate of experienced time.     

情绪词加工过程及其情绪效应特点：ERP的证据

语言是传递情绪信息的重要媒介, 探讨情绪语言的加工过程一直是情绪研究的重点。文章聚焦于情绪词加工的ERP研究, 介绍了情绪词加工中的ERP成分、效价与唤醒度的作用关系, 以及情绪词情绪效应的特点。情绪词加工的ERP成分包括非常早期的P1-N1成分, 早期的EPN成分和晚期的LPP成分; 效价和唤醒度均在情绪词加工中具有重要作用, 但两者的关系还未得到一致结论。相比情绪图片, 情绪词加工所引发的情绪效应更弱, 并且存在积极效价偏向。今后的研究还需进一步探讨影响情绪词情绪效应产生的相关因素; 进一步区分情绪标注词和情绪负载词, 探讨两类情绪词加工的异同。此外, 结合眼动追踪技术探讨自然语境中的情绪词加工机制也是未来研究的一个重要方向。     

Sexual desire,not hypersexuality,predicts self-regulation of sexual arousal

A person's ability to control their own sexual arousal is important both to reduce the risks associated with some sexual behaviours and to respond sexually with intimate partners. A lack of control over sexual urges is a proposed feature of “hypersexual disorder”, though some evidence suggests that sexual desire predicts the self-regulation of sexual arousal better than hypersexuality. In the current study, a sample (N = 116) of men and women recruited from community ads viewed a series of 20-second neutral and sexual films. Before each sexual film, participants were instructed to increase their sexual arousal, decrease their sexual arousal or respond as usual. Higher levels of desire for sex with a partner consistently predicted failures to downregulate sexual arousal. Hypersexuality was unrelated. These findings replicate Winters et al.'s study and extend their findings by including upregulation, women, a new measure of hypersexuality and a higher-trial design.     

Toward a cumulative science of emotion: a functional-cognitive framework for emotion research

ABSTRACT

Definitions of emotion and emotional phenomena are often infused with intuitions and theoretical ideas about what is “truly” emotional. Although these intuitions and ideas motivate people to study emotion, their prominence at the conceptual level can hamper progress in emotion research. In this paper, we argue that there is merit in defining emotional phenomena as much as possible in terms of behavioural principles that have been developed outside of emotion research. We clarify that such a functional approach is compatible with, and can even strengthen, cognitive approaches to emotion research. This functional-cognitive perspective reveals ways to increase the cumulative nature of emotion research and to surpass initial intuitions and theoretical ideas.     

Does the horny man think women want him too? Effects of male sexual arousal on perceptions of female sexual willingness

ABSTRACT

Disputes over acquaintance rape typically center on the issue of whether the alleged victim consented to sex. Disputed sexual encounters often take place when one or both involved parties is sexually aroused, and this arousal might influence the extent to which the parties perceive sexual consent. Two studies tested the effects of men’s sexual arousal on their interpretations of the extent to which 25 hypothetical female behaviors reflected sexual willingness. Arousal was manipulated via written fantasies (Study 1) or exposure to erotic material (Study 2). Manipulated arousal and individual differences in rated arousal were each associated with greater perceptions of female sexual willingness. Manipulated arousal was significant only for single men in Study 2. Findings suggested present-state sexual arousal affects single men’s interpretations of women’s sexual willingness. Men’s sexual arousal might prominently contribute to misunderstandings in sexual communication.     

Age-related hearing loss associated with altered response efficiency and variability on a visual sustained attention task

ABSTRACT

This study investigated the association between age-related hearing loss (ARHL) and differences in response efficiency and variability on a sustained attention task. The study population comprised 32 participants in a hearing loss group (HLG) and 34 controls without hearing loss (CG). Mean reaction time (RT) and accuracy were recorded to assess response efficiency. RT variability was decomposed to examine temporal aspects of variability associated with neural arousal and top-down executive control of vigilant attention. The HLG had a significantly longer mean RT, possibly reflecting a strategic approach to maintain accuracy. The HLG also demonstrated altered variability (indicative of greater decline in neural arousal) but maintained executive control that was significantly predictive of poorer response efficiency. Adults with ARHL may rely on higher-order attention networks to compensate for decline in both peripheral sensory function and in subcortical arousal systems which mediate lower-order automatic neurocognitive processes.
