The colour naming of socially threatening words

An emotional Stroop task was used to investigate colour naming of socially threatening words in individuals who possess a repressive coping style. The Marlowe-Crowne scale (MC) and the Bendig version of the Taylor Manifest Anxiety Scale (MAS) were used to select repressor and control subjects, who subsequently completed the Stroop task. Repressors (high MC, low MAS) did not show an emotional Stroop effect, whereas low anxious (low MC, low MAS), high anxious (low MC, high MAS) and defensive high anxious (high MC, high MAS) all exhibited retarded colour naming of emotional words compared with neutral words. These results are discussed in terms of previous research in this area.     

Mere exposure has differential effects on attention allocation to threatening and neutral stimuli

The mere exposure (ME) effect is the phenomenon whereby familiar stimuli are rated more positively than their novel counterparts (e.g., Zajonc, 1968). Though the effect of mere familiarity on a variety of affective judgments is robust and well documented, relatively little research has examined the effects of ME on other non-affective outcomes. The current research addressed this issue by examining the effects of ME on selective attention to threatening and neutral stimuli. We predicted and found that threatening stimuli, which typically arouse negative affect and capture attention, were attended to less following ME; conversely, neutral stimuli, which typically do not arouse affect nor capture attention, were attended to more following ME. The implications of these findings for the literatures on mere exposure and attention are discussed as are speculations about mediators of these effects.     

The effects of exposure to slender and muscular images on male body dissatisfaction

This research examined the effects of appearance-based comparisons to muscular and slender idealized male bodies and the contribution of internalization and social comparison to change in body dissatisfaction. Participants were 111 male undergraduates who completed measures of body dissatisfaction, internalization, and social comparison and viewed images of either muscular or slender men in advertisements or product-only advertisements. Results indicated that exposure to both muscular and slender images was associated with an increase in body dissatisfaction, with no significant differences in the change in body dissatisfaction between the two image conditions. Internalization and trait social comparison were each associated with an increase in body dissatisfaction; however, upward social comparison was only a significant predictor of a change in body dissatisfaction for the males who viewed muscular images. These results highlight the impact of slender models on young men's body dissatisfaction and support the examination of media literacy interventions with this population.     

The reliability of eyetracking to assess attentional bias to threatening words in healthy individuals

Eyetracking is commonly used to investigate attentional bias. Although some studies have investigated the internal consistency of eyetracking, data are scarce on the test–retest reliability and agreement of eyetracking to investigate attentional bias. This study reports the test–retest reliability, measurement error, and internal consistency of 12 commonly used outcome measures thought to reflect the different components of attentional bias: overall attention, early attention, and late attention. Healthy participants completed a preferential-looking eyetracking task that involved the presentation of threatening (sensory words, general threat words, and affective words) and nonthreatening words. We used intraclass correlation coefficients (ICCs) to measure test–retest reliability (ICC > .70 indicates adequate reliability). The ICCs(2, 1) ranged from –.31 to .71. Reliability varied according to the outcome measure and threat word category. Sensory words had a lower mean ICC (.08) than either affective words (.32) or general threat words (.29). A longer exposure time was associated with higher test–retest reliability. All of the outcome measures, except second-run dwell time, demonstrated low measurement error (<6%). Most of the outcome measures reported high internal consistency (α > .93). Recommendations are discussed for improving the reliability of eyetracking tasks in future research.     

Finding words for feelings: The relationship between personality disorders and alexithymia

This study examined whether personality disorders (PDs) are associated with alexithymic features at varying levels of comorbid psychopathology distress. 167 psychiatric outpatients completed the Toronto Alexithymia Scale (TAS) and the General Severity Index (GSI) of the SCL90-revised. Bootstrapping analyses were performed to test whether the PD/alexithymia relationship was moderated by psychopathology distress (GSI). The overall number of PD criteria was associated with cognitive aspects of alexithymia (i.e., Externally Oriented Thinking, EOT) only at low/moderate levels of distress. Borderline criteria predicted EOT only when distress was low, while avoidant and dependent criteria were independently related with EOT. No association was found between other PDs and alexithymia facets. Thus, within clinical samples the alexithymia/PD association is mainly explained by comorbid psychopathology; however, individuals with avoidant, dependent and borderline features might have a specific difficulty with focusing on internal reality, even when their current symptom distress is low.     

The effects of culture and self-construal on responses to threatening health information

Objective: The current studies examined if cultural and self-construal differences in self-enhancement extended to defensive responses to health threats.

Design: Responses to fictitious medical diagnoses were compared between Asian-Americans and European-North Americans in Experiment 1 and between Canadians primed with an interdependent versus an independent self-construal in Experiment 3. In Experiment 2, the responses of Chinese and Canadians who were either heavy or light soft drink consumers were assessed after reading an article linking soft drink consumption to insulin resistance.

Main outcome measure: The primary-dependent measure reflected participants’ defensiveness about threatening versus nonthreatening health information.

Results: In Experiment 1, all participants responded more defensively to an unfavourable than a favourable diagnosis; however, Asian-Americans responded less defensively than did European-North Americans. In Experiment 2, all high soft drink consumers were less convinced by the threatening information than were low soft drink consumers; however, among high consumers, Chinese changed their self-reported consumption levels less than did European-Canadians. In Experiment 3, interdependence-primed participants responded less defensively to an unfavourable diagnosis than did independence-primed participants.

Conclusion: Defensive reactions to threatening health information were found consistently; however, self-enhancement was more pronounced in individuals with Western cultural backgrounds or independent self-construals.     

Putting feelings into words: affect labeling disrupts amygdala activity in response to affective stimuli

Putting feelings into words (affect labeling) has long been thought to help manage negative emotional experiences; however, the mechanisms by which affect labeling produces this benefit remain largely unknown. Recent neuroimaging studies suggest a possible neurocognitive pathway for this process, but methodological limitations of previous studies have prevented strong inferences from being drawn. A functional magnetic resonance imaging study of affect labeling was conducted to remedy these limitations. The results indicated that affect labeling, relative to other forms of encoding, diminished the response of the amygdala and other limbic regions to negative emotional images. Additionally, affect labeling produced increased activity in a single brain region, right ventrolateral prefrontal cortex (RVLPFC). Finally, RVLPFC and amygdala activity during affect labeling were inversely correlated, a relationship that was mediated by activity in medial prefrontal cortex (MPFC). These results suggest that affect labeling may diminish emotional reactivity along a pathway from RVLPFC to MPFC to the amygdala.     

Don't be afraid of irrelevant words: The emotional Stroop effect is confined to attended words

The emotional Stroop effect denotes slower responses to the colour of negative words (e.g., death) compared to neutral words (e.g., mug). Popular explanations assume a general power of negative words to capture visual attention. However, in the typical task, the irrelevant word stimulus and the relevant colour stimulus are perceptually integrated. We compared interference from negative words, which were part of the relevant visual object, to interference from negative words that were part of an irrelevant object, or occurred in the background, respectively. Results showed that only negative words in the relevant object delayed colour-naming responses, compared to neutral words. Negative words outside the relevant object failed to affect performance. This finding is at odds with the claim that negative words could capture spatial or object-based mechanisms of visual attention. However, the finding is consistent with the idea that negative words interfere with the allocation of dimensional attention to different features of an attended object.     

The action congruency effect on the feelings of agency

Previous studies suggest that the sense of agency (SoA), the feeling of control about one’s own actions and ensuing effects is also generated during action selection processes. We investigate whether the conflict at the action selection stage induced by a supraliminal stimulus, modulates an implicit measure of SoA, namely intentional binding. Furthermore, we were interested to investigate the influence of different types of stimulus-response compatibility on SoA. To this aim we compared the influence of an automatic imitation task and a stroop-like task on intentional binding. In both tasks participants performed congruent and incongruent fingers movements (key release) in response to an external stimulus. Their movements caused an effect and participants estimated the time between their action and the ensuing effect. We found a reduced intentional binding effect in incongruent compared to congruent conditions in both tasks. The results are discussed within the theoretical framework of the fluency of action.     

The role of exposure to isolated words in early vocabulary development

Fluent speech contains no known acoustic analog of the blank spaces between printed words. Early research presumed that word learning is driven primarily by exposure to isolated words. In the last decade there has been a shift to the view that exposure to isolated words is unreliable and plays little if any role in early word learning. This study revisits the role of isolated words. The results show (a) that isolated words are a reliable feature of speech to infants, (b) that they include a variety of word types, many of which are repeated in close temporal proximity, (c) that a substantial fraction of the words infants produce are words that mothers speak in isolation, and (d) that the frequency with which a child hears a word in isolation predicts whether that word will be learned better than the child's total frequency of exposure to that word. Thus, exposure to isolated words may significantly facilitate vocabulary development at its earliest stages.     

The effect of set size on the latency to name words

The experiment attempted to determine whether or not Ss' verbal reaction time to name words was influenced by the number of possible word stimuli in a set. It was suggested that a discrepancy between the results of previous investigators was an artefact of the manner in which some of the data had been analysed. The results of the experiment indicate that set size does have a small but significant effect on reaction time to this task.     

Women's exposure to thin-and-beautiful media images: body image effects of media-ideal internalization and impact-reduction interventions

Exposure to media images of thin-and-beautiful women negatively affects the body image and mood states of young women. However, not all women are equally susceptible to these effects. The present experimental investigation with 123 young college women evaluated the moderating effects of the extent of internalization of media ideals. It also examined the preventative impact of two brief interventions (i.e., media literacy information with and without a dissonance-induction procedure). Results indicated that relative to a control group, the exposure to thin-and-beautiful media images adversely influenced the state body image of participants with high internalization levels. Media-literacy psychoeducation prior to the media exposure prevented this adverse effect. Adding a pre-exposure dissonance-induction procedure did not significantly enhance the preventative effects relative to psychoeducation alone. These results and their implications for the treatment and prevention of body image disturbances are discussed in the context of the empirical literature on the media's effects on body image.     

Reactions to heard words: varying emotional content and frequency of exposure

The authors aurally presented words varying in emotional content and frequency of exposure to 56 participants during (a) a study phase in which 288 words (72 separate words with repetitions) were presented and (b) a test phase in which participants were presented with the 72 words from the study phase along with 24 new words. In the test phase, participants responded to these 96 words with either a recognition response or a likability response. The recognition results indicated that increased exposure produced increased recognition; however, high arousal and negative valence words produced higher false positive scores. The likability scores revealed an overall mere exposure effect (MEE). However, words of low arousal and of positive valence did not show the MEE.     

Hurt feelings and four letter words: Swearing alleviates the pain of social distress

Methods for alleviating physical pain are increasingly found to attenuate social pain. Recent evidence suggests that swearing may attenuate sensitivity to physical pain. This study examined whether swearing similarly attenuates two consequences of social distress: social pain and exclusion‐induced hyperalgesia. Sixty‐two people wrote about an autobiographical experience of exclusion or inclusion. Then they repeated a swear or neutral word for 2 minutes followed by measures of social and physical pain. Excluded non‐swearers reported feeling more social pain and greater sensitivity to physical pain compared with included non‐swearers. Excluded swearers reported less social pain than excluded non‐swearers and no heightened sensitivity to physical pain. The findings suggest that social and physical pain are functionally similar and that swearing attenuates social pain.     

Sound specificity effects in spoken word recognition: The effect of integrality between words and sounds

Recent evidence has shown that nonlinguistic sounds co-occurring with spoken words may be retained in memory and affect later retrieval of the words. This sound-specificity effect shares many characteristics with the classic voice-specificity effect. In this study, we argue that the sound-specificity effect is conditional upon the context in which the word and sound coexist. Specifically, we argue that, besides co-occurrence, integrality between words and sounds is a crucial factor in the emergence of the effect. In two recognition-memory experiments, we compared the emergence of voice and sound specificity effects. In Experiment 1 , we examined two conditions where integrality is high. Namely, the classic voice-specificity effect (Exp. 1a) was compared with a condition in which the intensity envelope of a background sound was modulated along the intensity envelope of the accompanying spoken word (Exp. 1b). Results revealed a robust voice-specificity effect and, critically, a comparable sound-specificity effect: A change in the paired sound from exposure to test led to a decrease in word-recognition performance. In the second experiment, we sought to disentangle the contribution of integrality from a mere co-occurrence context effect by removing the intensity modulation. The absence of integrality led to the disappearance of the sound-specificity effect. Taken together, the results suggest that the assimilation of background sounds into memory cannot be reduced to a simple context effect. Rather, it is conditioned by the extent to which words and sounds are perceived as integral as opposed to distinct auditory objects.     

The effect of positive feelings on risk taking: When the chips are down

Two studies conducted simultaneously investigated the influence of positive affect on risk taking. Results of the study, which employed an actual measure of subjects' willingness to bet something of value, supported the prediction of an interaction between level of risk and positive affect: subjects who had reason to be feeling elated bet more than control subjects on a low-risk bet, but wagered less than controls on a high-risk bet. At the same time, in contrast, a study involving hypothetical risk-taking showed that in general subjects were more willing to take the chance as probability of success went up; but that elated subjects were more daring than controls on a “long shot.” Differences in hypothetical vs real risk taking were noted, and the complexity (the interaction) of the influence of positive feelings on real risk taking was emphasized. The results were related to other research suggesting an influence of feeling states on cognitive processes and decision making.     

Taboo words: The effect of emotion on memory for peripheral information

In three experiments, we examined memory for peripheral information that occurred in the same context as emotion-inducing information. In the first two experiments, participants studied either a sentence (Experiment 1) or a pair of words (Experiments 2A—2C) containing a neutral peripheral word, as well as a neutral, negative-valence, or taboo word, to induce an emotional response. At retrieval, the participants were asked to recall the neutral peripheral word from a sentence fragment or emotion-inducing word cue. In Experiment 3, we presented word pairs at encoding and tested memory with associative recognition. In all three experiments, memory for peripheral words was enhanced when it was encoded in the presence of emotionally arousing taboo words but not when it was encoded in the presence of words that were only negative in valence. These data are consistent with priority-binding theory (MacKay et al., 2004) and inconsistent with the attention-narrowing hypothesis (Easterbrook, 1959), as well as with object-based binding theory (Mather, 2007).     

威胁相关面孔表情对眼睛注视方向知觉的影响

以往研究发现眼睛注视方向知觉受面孔表情的影响,愤怒面孔相较于恐惧面孔更倾向被判断为看着观察者。虽然研究者对此提出了不同的解释,但目前尚不清楚愤怒和恐惧表情在注视方向知觉中的这种差异影响到底来自于面孔的结构信息还是物理特征信息。本研究采用注视方向辨别任务,计算直视知觉范围（The Cone of Direct Gaze,CoDG）为因变量,分别以直立,倒置及模糊图片为实验材料,试图通过分离面孔结构信息和物理特征信息,对以上问题进行探讨。结果发现在保留面孔全部信息的情况下（实验1）愤怒面孔的CoDG大于恐惧面孔;在破坏结构信息加工,只保留特征信息加工的情况下（实验2））愤怒和恐惧表情在直视知觉范围上的差异消失了;在削弱物理特征信息加工,保留结构信息加工的情况下（实验3）二者在CoDG上的差异又复现。本研究结果说明不同威胁性面孔表情对眼睛注视知觉的影响主要来自于二者在与情绪意义相关的结构信息加工上的不同,而二者非低级的物理信息上的差异,支持信号共享假说和情绪评价假说对威胁性面孔表情与注视方向整合加工解释的理论基础。
