Affective responses to body stimuli: comparing male and female bodies with cropped heads and masked faces

Three studies were conducted to determine whether headless bodies evoke affective responses that might confound neuroimaging and electrophysiological findings. In Experiment 1, 224 participants rated pictures, including bodies with cropped heads and masked faces, for disgust, fear, naturalness, valence and arousal. In Experiment 2, 38 participants viewed the same images during a free word association task, whilst in Experiment 3 galvanic skin responses were measured as 57 participants completed a similar rating task to that in Experiment 1. No differences were found between responses elicited by bodies without heads versus bodies with masked faces, although female bodies were thought of more positively than male bodies. This suggests that headless bodies are not abhorrent and are appropriate stimuli for investigating body-selective perceptual processes as they do not evoke face-processing mechanisms. Our findings also suggest that differences between male and female body viewing should be considered when investigating visual body perception.     

A qualitative study exploring the experience of people with IBD and elevated symptoms of anxiety and low mood and the type of psychological help they would like

Background: People with inflammatory bowel disease (IBD) are at increased risk of developing anxiety and low mood. We sought to explore the experience of people with IBD and moderate–severe symptoms of anxiety/low mood to identify psychological processes which could be targeted in psychological interventions, as well as the kind of psychological support preferred.

Methods: Twenty-five participants with IBD and moderate–severe symptoms of anxiety/low mood were recruited for interview. Template analysis was utilised to analyse interview data. We explored the situations, cognitions and behaviour linked to symptoms of anxiety and low mood by people with IBD, as well as the kind of psychological help preferred.

Results: Two themes were identified within participants accounts of symptoms of anxiety; ‘under performance’ and ‘preventing an accident’. Two further themes were identified for symptoms of low mood; ‘lack of understanding’ and ‘stigma’. Expertise and understanding was the main theme identified for the type of psychological help desired.

Conclusion: The analysis highlights situations, cognitions and behaviour linked to anxiety and low mood by people with IBD and the type of psychological support desired. Our findings link to the knowledge and competencies set for psychological therapist working with long-term conditions.

Return of experimentally induced chocolate craving after extinction in a different context: divergence between craving for and expecting to eat chocolate

Unlike in fear conditioning, little attention has been devoted to extinction and renewal in appetitive conditioning, despite its relevance for extinction-based addiction treatments. We developed a paradigm, using a specific tray as a conditioned stimulus (CS) for eating chocolate (unconditioned stimulus, US), to investigate the effects of context change on acquisition and extinction of conditioned chocolate craving using an ABA renewal design. In Study 1 (n=32), participants successfully acquired chocolate craving, but unlike what is commonly observed in fear conditioning, craving did not extinguish. In Study 2, we separately assessed craving and US expectancy in a between-subjects design (n=64). US-expectancy data showed acquisition, extinction and renewal in the ABA group. The craving data did not follow this pattern, suggesting different mechanisms for craving and US expectancy. Similarities and differences between craving and US expectancy, as well as practical implications, are discussed.     

压力性生活事件对青少年主观幸福感的影响机制

在应对的交互作用模式、压力缓冲与压力易损性假说基础上提出一个有调节的中介模型,探讨应对方式在青少年压力性生活事件与主观幸福感之间的中介效应,以及情绪智力的调节效应。被试为1670名青少年,研究工具包括青少年生活事件量表、特质应对方式问卷、情绪智力量表和主观幸福感问卷。结果显示:(1)应对方式在压力性生活事件与主观幸福感之间起部分中介作用。(2)情绪智力在压力性生活事件对应对方式的影响中起调节作用:在低压力性生活事件下,高情绪智力的青少年应对方式较好,在高压力性生活事件下,不论情绪智力如何,应对方式都不好,情绪智力是压力易损因子。     

青少年感觉寻求与烟酒使用的关系:一个有中介的调节模型

在生态系统理论和社会学习理论基础上提出一个有中介的调节模型,探讨青少年感觉寻求与烟酒使用的关系,以及压力性生活事件的调节效应和结交不良同伴的中介效应。被试为660名青少年,研究工具包括青少年感觉寻求量表、压力性生活事件量表、不良同伴问卷和烟酒使用问卷。结果显示:(1)青少年感觉寻求是烟酒使用的风险因素。(2)压力性生活事件对感觉寻求与烟酒使用之间的关系具有风险增强的调节效应。(3)这种调节效应以结交不良同伴为中介变量。因此,青少年感觉寻求与烟酒使用之间既存在调节效应又存在中介效应。     

Familiarity with the test environment improves escape responses in the crimson spotted rainbowfish, Melanotaenia duboulayi

Animals that are familiar with their environment have been reported to have greater survivorship for a number of reasons related to their knowledge of the terrain, which they recall from memory. In an initial experiment rainbowfish significantly improved their escape response towards a novel trawl apparatus over a sequence of five runs. Escape latencies were still low during a subsequent exposure 11 months after the initial exposure. While part of the improvement in escape success was certainly due to learning associated with the location of the escape route, it is likely that this was aided by habituation to the tank environment and the experimental protocol. In a follow-up experiment, fish that had been kept in the experimental tank for 3 weeks prior to testing, and had become familiar with the test tank, showed significantly lower escape latencies and escaped more often than fish that were not familiar with the test environment. It is suspected that familiarity with the testing arena decreased stress and enabled individuals to detect novel stimuli and devote more attention to them. These findings have significant implications for experimenters studying aspects of animal cognition, such as learning and memory, in laboratory situations.

A COMPARISON OF PEER VIDEO MODELING AND SELF VIDEO MODELING TO TEACH TEXTUAL RESPONSES IN CHILDREN WITH AUTISM

Peer video modeling was compared to self video modeling to teach 3 children with autism to respond appropriately to (i.e., identify or label) novel letters. A combination multiple baseline and multielement design was used to compare the two procedures. Results showed that all 3 participants met the mastery criterion in the self‐modeling condition, whereas only 1 of the participants met the mastery criterion in the peer‐modeling condition. In addition, the participant who met the mastery criterion in both conditions reached the criterion more quickly in the self‐modeling condition. Results are discussed in terms of their implications for teaching new skills to children with autism.     

OPTIMIZING LINKED PERCEPTUAL CLASS FORMATION AND TRANSFER OF FUNCTION

A linked perceptual class consists of two distinct perceptual classes, A′ and B′, the members of which have become related to each other. For example, a linked perceptual class might be composed of many pictures of a woman (one perceptual class) and the sounds of that woman's voice (the other perceptual class). In this case, any sound of the woman's voice would occasion the selection of any picture of the woman and vice versa. In addition, after learning to name the woman in the presence of one picture, that name would be uttered when presented with all of the images of the woman's face and all of the sounds of her voice. This study involved 15 participants and sought to (a) maximize the percentage of participants who formed linked perceptual classes, and (b) determine whether those classes acted as transfer networks, that is, whether the discriminative function of one class member would generalize to other members of the class and not to members of a different class. The rate of emergence of each linked perceptual class was maximized by establishing a single class‐linking conditional relation between the clearest member of one class used as a sample stimulus and the most ambiguous member of the other class used as a comparison stimulus. Class formation was demonstrated using the serial and programmed presentation of A′–B′ probes that consisted of untrained pairs of stimuli drawn from the A′ and B′ classes. Most participants showed immediate emergence of the two linked perceptual classes. The remaining participants showed delayed emergence following a second exposure to each originally error‐producing probes. Once the linked perceptual classes had emerged, a differential response to a specific member of one perceptual class generalized mostly or completely to the other members of that linked class and rarely, if ever, to members of the other linked class. Thus, generalization did not depend on the specific class members that had been used for discrimination training.     

不同认知偏好对大学生情感反应的影响：短期利益和长期代价

对99名大学生进行一个学期的追踪调查,探讨不同认知偏好对他们状态性情感反应的影响以及这种影响从长期看是利是弊的问题。结果发现：1）与其他组被试相比,积极认知偏好组产生了更少消极情感反应和更高情感反应积极性;2）认知偏好对个体情感反应的不同影响是暂时的,从长期看,既没有累积成稳定的情感健康差异也没有产生情感代价。最后对认知偏好的适应性进行了讨论。
