The effects of attention on ear advantages in dichotic listening to words and affects

This study examined the effects of attention on ear advantages using dichotic listening to words and affects, a focused-attention paradigm. We compared the mixed condition, in which attention is switched between the ears in each trial, to the blocked condition, in which attention is directed to one ear for an entire block of trials. Results showed a decreased right ear advantage for word processing only in the mixed condition and an increased left ear advantage for emotion processing in both attention conditions for hits index. The mixed condition showed smaller laterality effects than the blocked condition for words with respect to hits index, while increasing right ear predominance for intrusions. The greater percentage of intrusions in the right ear for the word task and in the mixed condition suggests that the right ear (left hemisphere) is most vulnerable to attention switching. We posit that the attention manipulation has a greater effect on word processing than on emotion processing and propose that ear advantages reflect a combination of the effects of attentional and structural constraints on lateralisation.     

Fear and anxiety modulate mental rotation

We used an emotional priming paradigm to investigate whether fear and anxiety modulate mental rotation of abstract three-dimensional objects (i.e., Shepard-Metzler figures). On each trial, participants viewed pairs of objects and decided whether the objects had the identical shape by mentally rotating the one on the right into congruence with the one on the left. The participants viewed a picture of a face—fearful or neutral—briefly before the pairs of objects appeared. Participants with high state anxiety, and not those with low state anxiety, rotated the objects more quickly after they saw fearful faces than after they saw neutral faces. This result not only documents that fear can improve mental rotation but also shows that this effect is modulated by the emotional arousal of the participants.     

Evidence of fast and automatic gender bias in affective priming

Previous studies have revealed a gender bias in ratings of the valence and intensity of supraliminally presented facial expressions of emotion such that positive emotions receive higher ratings when expressed by females and negative emotions receive higher ratings when expressed by males. However, surprisingly, this gender bias has not been investigated for suboptimal presentation of emotional expressions. Our first experiment aimed at investigating the existence of such a bias for very fast presentation of the stimulus (20 ms onset) on the basis of a classic priming procedure commonly used in affective priming studies that involved the use of a single prime. Our second experiment aimed at proposing a new method involving four fast, repeated presentations of the prime-target pairs (based on the innovative design proposed by Höschel and Irle), that could be used to reduce the gender bias in future studies in affective sciences. Results show that the classic procedure for subliminal affective priming seems, indeed, sensitive to gender bias, but that it is possible to maximise the affective effect and decrease the impact of the gender bias using repeated presentations of the prime.     

情绪唤起对执行功能的作用

执行功能是对基本认知加工进行有意心理控制的所有高级认知过程.最近10年,情绪唤起对执行功能的作用机制吸引愈来愈多的研究兴趣,其中,消极情绪(尤其焦虑、抑郁)已被普遍证实损害执行功能的运行效率;积极情绪如何作用执行功能尚不明确.鉴于后者研究中的理论假设匮乏,近年兴起的积极情绪的扩展建构理论以及动机维度模型,能为理解积极情绪如何作用执行功能提供线索与启发.未来研究应深入探讨不同动机强度的积极及消极情绪对执行功能的作用机制,在这之中也应细致区分情绪唤起与情绪刺激的不同效应.     

Emotional responses to a negative emotion induction procedure in Borderline Personality Disorder

The aim of this study was to determine if patients with Borderline Personality Disorder (BPD) present higher emotional response than healthy controls in a laboratory setting. Fifty participants (35 patients with BPD and 15 healthy controls) underwent a negative emotion induction procedure (presentation of standardized unpleasant images). Subjective emotional responses were assessed by means of self-reported questionnaires while biological reactivity during the procedure was measured through levels of salivary cortisol (sCORT) and alphaamylase (sAA). Patients with BPD exhibited significant lower cortisol levels and higher sAA levels compared to controls. Self-reported emotional reactivity did not give rise to differences between groups but participants with BPD did present higher levels of negative emotional intensity at baseline and during the entire procedure. The findings do not give support to the emotional hyperreactivity hypothesis in BPD. However, BPD patients presented heightened negative mood intensity at baseline, which should be considered a hallmark of the disorder. Further studies using more BPD-specific emotion inductions are needed to confirm the trends observed in this study.     

Cognitive and emotional empathy in typically developing children: The influence of age,gender, and intelligence

In the current study, the influence of age, gender and IQ on cognitive and emotional empathy in school-aged children and adolescents was examined adopting two behavioural paradigms: participants were shown film clips with different scenes of social interaction to which they were asked to respond. Thus, 134 children aged seven to 17 years (mean age = 138.4 months, sd = 31.66 months) were tested for emotion recognition, perspective taking and emotional empathy. Age strongly influenced components of cognitive empathy and explained 33.5% to 39.1% of the variance. Gender and IQ also were significant predictors, yet only explained 3% to 5%, respectively 8% to 9% of the variance. In contrast, neither age, gender nor IQ were related to emotional empathy. Results suggest developmental maturation of cognitive, but not emotional empathy throughout childhood and adolescence. To explain variability in emotional empathy, additional biological and psychosocial factors need to be studied.     

The effect of neutral and negative colour photographs on children's item directed forgetting

Intentional forgetting is an active process relying on cognitive mechanisms (e.g., rehearsal strategies and inhibition) developing during the elementary school years. Colour photographs might be rehearsed differently in memory than words, and therefore result in a different developmental pattern of intentional forgetting than previously acknowledged. Moreover, negative material is thought to be particularly reliant upon inhibitory mechanisms in order not to be encoded in memory. Thus, children's item-directed forgetting (DF) might develop differently both in relation to colour photographs in general and for negative pictorial stimuli in particular. The aim of the present study was to investigate item DF for colour photographs of neutral and negative valence in sixty-five school-aged children (8–12 years of age). In the present study, a DF effect was revealed irrespective of age for neutral images as well as negative images. Results are discussed in relation to potential mechanisms underlying item DF for colour photographs and how these affect development of intentional forgetting.     

A cluster-analytic approach to identity style classification: Four seems to be better than three

Abstract

In their previous study Crocetti, Berzonsky, and Meeus evaluated the usefulness of empirically-based methods of classification in the process of distinguishing subgroups characterized by different identity styles. They suggested that the four-cluster solution best reflected intra-individual differentiation. One of these groups had not been predicted in Berzonsky’s identity style theory – the group of individuals high in both the normative and the informational style. The aim of this study was to replicate this observation and to expand the perspective of Crocetti et al. to include the emotional functioning of individuals from the different clusters. We were interested in the differences between individuals who predominately used particular identity styles with respect to the personal identity processes (exploration and commitment), the proneness to experience the negative emotions of shame and guilt, and the more general difficulty in regulation of negative emotional states. The participants of the study were 202 Polish university students between the age of 19 and 27. The obtained results showed that the four-cluster solution was the most optimal one. The differences between individuals with different identity styles are presented and discussed.     

Early detection and avoidance of threatening faces during passive viewing

To evaluate whether there is an early attentional bias towards negative stimuli, we tracked participants' eyes while they passively viewed displays composed of four Ekman faces. In Experiment 1 each display consisted of three neutral faces and one face depicting fear or happiness. In half of the trials, all faces were inverted. Although the passive viewing task should have been very sensitive to attentional biases, we found no evidence that overt attention was biased towards fearful faces. Instead, people tended to actively avoid looking at the fearful face. This avoidance was evident very early in scene viewing, suggesting that the threat associated with the faces was evaluated rapidly. Experiment 2 replicated this effect and extended it to angry faces. In sum, our data suggest that negative facial expressions are rapidly analysed and influence visual scanning, but, rather than attract attention, such faces are actively avoided.     

Emotional target cues eliminate age differences in prospective memory

Cue saliency is known to influence prospective memory performance, whereby perceptually or conceptually distinct cues facilitate remembering and attenuate adult age-related deficits. The present study investigated whether similar benefits for older adults are also seen for emotional valence. A total of 41 older and 41 younger adults performed a prospective memory task in which the emotional valence of the prospective memory cues was manipulated. Emotionally valenced cues increased prospective memory performance across both groups. Age deficits were only observed when neutral (but not positive or negative) prospective cues were presented. Findings are consistent with predictions that salient cues facilitate participants' prospective memory performance and reduce age-related differences, while extending the concept of saliency to include emotional valence.
