Anxiety-related differences in affective categorizations of lexical stimuli

Effects of emotional valence on attention have been shown to occur even when stimuli are presented outside awareness. The impact of negative valence on stimulus processing has been demonstrated to be particularly salient in anxiety. Therefore, it has been hypothesized that compared to nonanxious individuals, anxious individuals have an enhanced ability to detect the valence of negative stimuli. However, it remains unclear whether anxious individuals are better at identifying the valence of threatening stimuli or, rather, more likely to label ambiguous stimuli as threatening. To investigate these hypotheses, high and low anxious participants categorized lexical stimuli as "safe" or "dangerous." Stimuli were presented at durations that allowed for both conscious (unmasked) and nonconscious (masked) processing. Results show that on masked trials, anxious individuals evidenced an enhanced ability to correctly classify threatening information, whereas nonanxious participants demonstrated an enhanced ability to correctly classify neutral or positive information. Signal detection analyses indicated results were explained by a response bias, whereby anxious individuals were more likely than nonanxious individuals to categorize masked words as threatening and nonanxious individuals were more likely to categorize masked words as nonthreatening. No group differences for nonword stimuli emerged, suggesting that anxiety-related response bias tendencies are activated only after detection of a weak semantic signal.     

发音人和语境变异与声调知觉

本文用Garner快速分类法研究了发音人规范化和语境补偿过程与声调知觉的关系。得到的主要结果是:(1)发音人变化对声调识别产生了显著的Gar-ner干扰;声调变化对男女声判别产生了同样的十扰。(2)语境变化对声调识别也产生了显著的Garner干扰。按照Garner方法的假设,这说明发音人规范化和语境变异补偿与声调识别之问是相互联系和相互影响的。(3)虽然发音人和语境同时变化引起的声调识别反应时延长约等于它们单独变化时反应时延长量之和,但正确率下降远大于单独变化时下降量之和。说明发音人和语境变异对声调识别的干扰不是独立的,它们之间存在相互作用。这种作用增加了声调识别的难度。     

Professional isolation and pandemic teleworkers’ satisfaction and commitment: The role of perceived organizational and supervisor support

BackgroundThe COVID-19 pandemic has abruptly and profoundly changed the way people interact with their organization, their colleagues and their supervisor.ObjectiveThis study assesses the effects of telework-induced professional isolation due to the pandemic. Drawing on organizational support theory, this study examines the relationship between professional isolation and satisfaction with the telework experience and affective organizational commitment during mandatory teleworking caused by the COVID-19 crisis. It does so by focusing on the moderating role of perceived organizational and supervisor support in these relations.MethodsData was collected via self-reported survey questionnaires from 728 pandemic teleworkers from various industry sectors in Quebec during the COVID-19 crisis. The study's hypotheses were tested using structural equation modeling (SEM), and moderation effects were probed with the Johnson-Neyman technique.ResultsThe results reveal that professional isolation negatively affects satisfaction with the telework experience, but does not affect affective organizational commitment. The relationship between satisfaction with telework and professional isolation was moderated by perceived organizational support, and the relationship between affective organizational commitment and professional isolation was moderated by perceived supervisor support.ConclusionThis study expands the organizational support theory by examining perceived organizational and supervisor support during a crisis as a counterbalance to a challenging social and organizational climate that has led to professional isolation. The implications of the findings as well as future directions for research on professional isolation and telework are discussed.

Effects of suppression and acceptance on emotional responses of individuals with anxiety and mood disorders

The present investigation compared the subjective and physiological effects of emotional suppression and acceptance in a sample of individuals with anxiety and mood disorders. Sixty participants diagnosed with anxiety and mood disorders were randomly assigned to one of two groups. One group listened to a rationale for suppressing emotions, and the other group listened to a rationale for accepting emotions. Participants then watched an emotion-provoking film and applied the instructions. Subjective distress, heart rate, skin conductance level, and respiratory sinus arrhythmia were measured before, during, and after the film. Although both groups reported similar levels of subjective distress during the film, the acceptance group displayed less negative affect during the post-film recovery period. Furthermore, the suppression group showed increased heart rate and the acceptance group decreased heart rate in response to the film. There were no differences between the two groups in skin conductance or respiratory sinus arrhythmia. These findings are discussed in the context of the existing body of research on emotion regulation and current treatment approaches for anxiety and mood disorders.     

Interactions between emotion regulation strategies and affective style: Implications for trait anxiety versus depressed mood

Affective style reflecting approach and inhibition is thought to be associated in distinct ways with anxious versus depressed mood; relatively few studies, however, consider how the interaction between affective style and the strategies individuals use to regulate mood and emotion might influence these associations. Sixty-seven non-disordered adults self-reported on their use of two emotion regulation strategies (cognitive reappraisal and expressive suppression), behavioral approach (BAS) and behavioral inhibition sensitivity (BIS) dimensions of affective style, and anxious and depressed mood (trait anxiety and symptoms of depression). Trait anxiety versus depressed mood was associated with unique interactive patterns of emotion regulation and affective style: enhanced use of reappraisal was linked to less depressed mood in those reporting low BAS, whereas high suppression was linked to greater trait anxiety in those reporting low BIS. The implications of findings for typical emotional processes and for clinical disorders and interventions are discussed.     

Internalizing Symptoms and Affective Reactivity in Relation to the Severity of Aggression in Clinically Referred,Behavior-Disordered Children

We examined the affective correlates of aggression in children referred to a partial hospitalization program for the treatment of behavior disorders who did not have a mood or anxiety disorder. Parent and teacher ratings of the children’s impulsivity, internalizing symptoms, affective reactivity, and aggression were examined for their interrelationships and then entered into regression analyses to predict the child’s level of aggression in the home, at school, and in the treatment program. Intercorrelations among three affective reactivity factors were modest. Both internalizing symptoms and affective reactivity contributed to aggression severity beyond impulsivity and demographics. Only child irritability predicted treatment program aggression. Because of their potential role in understanding children’s behavioral disturbances, internalizing symptoms and negative emotionality merit careful assessment and treatment in treatment programs serving hard-to-manage children with behavior disorders.     

NARROW HEDONISM

Narrow hedonism is defined and defended, as a view according to which pleasurable states are individuated as concrete and total experiential situations of a sentient being at a time. Typical of such situations is that, when we are in them, we are at a certain hedonic level. They feel in a certain way for the creature in them. On this understanding of narrow hedonism, which is the only one making good sense of the theory and which was probably also intended by classical hedonists such as Bentham and Edgeworth, standard objections to hedonism, based on the claim that different pleasures have nothing in common, can be set to one side as misplaced and irrelevant. It is also hard to see how this kind of hedonism can be refined, or revised, in the direction indicated by J.S. Mill, when he wants to distinguish “higher” pleasures from “lower” ones. On this understanding of hedonism, we must claim that, those who want to follow Mill will have to rely on non-hedonistic intuitions and thus desert the hedonist camp altogether.     

Positive and negative associations underlying ambivalent attitudes

In two studies, we compared the strength of positive and negative associations of ambivalent attitudes to those of nonambivalent attitudes. In Study 1, results from an implicit association task showed that, in contrast to nonambivalent attitudes, ambivalent attitudes were characterized by strong positive and negative associations. In Study 2 responses to ambivalent attitude objects were faster following a positive as well as following a negative prime, compared to a non-word prime, whereas for neutral attitude objects prime type did not influence response times. Results provide direct evidence for the assumption that both positive and negative associations of ambivalent attitudes are relatively strong. Implications for attitude strength and attitude structure are discussed.     

Valence specific laterality effects in prosody: expectancy account and the effects of morphed prosody and stimulus lead

The majority of studies have demonstrated a right hemisphere (RH) advantage for the perception of emotions. Other studies have found that the involvement of each hemisphere is valence specific, with the RH better at perceiving negative emotions and the LH better at perceiving positive emotions [Reuter-Lorenz, P., & Davidson, R.J. (1981) Differential contributions of the 2 cerebral hemispheres to the perception of happy and sad faces. Neuropsychologia, 19, 609-613]. To account for valence laterality effects in emotion perception we propose an 'expectancy' hypothesis which suggests that valence effects are obtained when the top-down expectancy to perceive an emotion outweighs the strength of bottom-up perceptual information enabling the discrimination of an emotion. A dichotic listening task was used to examine alternative explanations of valence effects in emotion perception. Emotional sentences (spoken in a happy or sad tone of voice), and morphed-happy and morphed-sad sentences (which blended a neutral version of the sentence with the pitch of the emotion sentence) were paired with neutral versions of each sentence and presented dichotically. A control condition was also used, consisting of two identical neutral sentences presented dichotically, with one channel arriving before the other by 7 ms. In support of the RH hypothesis there was a left ear advantage for the perception of sad and happy emotional sentences. However, morphed sentences showed no ear advantage, suggesting that the RH is specialised for the perception of genuine emotions and that a laterality effect may be a useful tool for the detection of fake emotion. Finally, for the control condition we obtained an interaction between the expected emotion and the effect of ear lead. Participants tended to select the ear that received the sentence first, when they expected a 'sad' sentence, but not when they expected a 'happy' sentence. The results are discussed in relation to the different theoretical explanations of valence laterality effects in emotion perception.
