Personality traits and affective states: Relationships with and without affect induction

Substantial evidence shows that extraversion is related to positive affect (PA) and neuroticism is related to negative affect (NA), and there are several possible explanations for these relationships. The current paper replicates these findings and examines relationships between the other Big Five traits with general positive and negative states (N = 257). Agreeableness was negatively related to NA, while conscientiousness and openness were positively related to PA. Next, affect was induced and extraversion and conscientiousness predicted changes in affect following an affect-induction (N = 262). The current findings support some theoretical understandings of broad personality traits and their relationships to general affect, and also suggests some refinements.     

Cortical functional connectivity is associated with the valence of affective states

The study investigates the relationships between the valence of affective states and the cortical patterns of functional connectivity. The information flow rate and direction were estimated by means of Directed Transfer Function (DTF), a multivariate method based on Granger causality. It was calculated on EEG activity recorded during mental imagery tasks. As a result, three regions were revealed as main network hubs, where the information outflow changed specifically with valence: the anterior orbitofrontal cortex, and the right posterior and right temporal area. The role of these structures in synchronizing the cortical affective network as well as in mediating different aspects of emotional state is discussed.     

Evidence that episodic memory impairment during tobacco abstinence is independent of attentional mechanisms

Previous studies have demonstrated reductions in episodic memory during nicotine withdrawal. However, these studies have been unable to dissociate memory reductions from losses in attention associated with tobacco abstinence. In the present study, the authors sought to determine whether episodic memory reduction is a primary effect of nicotine withdrawal during tobacco abstinence. Heavy smokers were tested when smoking normally and following 24 hrs of abstinence. Participants were tested with a recognition memory task in which items were studied under full and divided attention conditions. Forward digit span and backward digit span were also included as control measures. Withdrawal was associated with a reduction in memory performance that was independent of attention at encoding. The authors conclude that impairment of episodic memory is a primary effect of nicotine withdrawal during tobacco abstinence. Further research is required to determine if this is associated with continued use of tobacco and cessation failures.     

A neutral face is not neutral even if you have not seen it: social anxiety disorder and affective priming with facial expressions

Cognitive theories suggest that social anxiety disorder (SAD) is characterized by biased processing of negative facial expressions. Recently, however, it has been proposed that the fear of positive evaluation may play an additional, important role. In order to investigate which specific expressions evoke biased processing, 15 patients diagnosed with SAD and 15 non-anxious controls (NACs) completed an affective priming procedure: they rated neutral symbols which were preceded by sub-optimally presented primes of angry, neutral, and smiling faces. Patients with SAD rated the symbols significantly more negatively than NACs when they were primed with a neutral face. In addition, SAD patients tended to rate all symbols significantly more negatively suggesting that all faces (negative, positive, and neutral) are threatening to SAD patients.     

Validation of affective and neutral sentence content for prosodic testing

Conducting a study of emotional prosody often requires that one have a valid set of stimuli for assessing perceived emotion in vocal intonation. In this study, we created a list of sentences with both affective and neutral content, and then validated them against rater opinion. Participants read sentences with content that implied happiness, sadness, anger, fear, or neutrality and rated how well they could imagine each sentence being expressed in each emotion. Coefficients of variation and intraclass correlations were calculated to narrow the list to affective sentences that had high agreement and neutral sentences that had low agreement. We found that raters could easily identify most emotional content and did not ascribe any unique emotion to most neutral content. We also found differences between the intensity of male and female ratings. The final list of sentences is available on the Internet (www.med.upenn.edu/bbl/) and can be recorded for use as stimuli for prosodic studies.     

Pictures and anaphora: Evidence for independent processes

Pictures enhance our comprehension of written texts, but the perceptual and cognitive processes that underlie this effect have not been identified. Because integrating the information contained in a text places demands on working memory, the effect of a picture may be to expand the functional capacity of working memory and thereby to facilitate comprehension. Reasoning thus, we predicted that the availability of a diagram would interact with the difficulty of resolving anaphoric references in texts. The resolution of an anaphor distant from its antecedent (which should stress working memory) should benefit greatly from the presentation of a picture, whereas the resolution of an anaphor near to its antecedent should benefit less from the presentation of a picture. Picture availability and distance separating the anaphor from its antecedent were manipulated in experiments involving both cumulative and moving window presentations of texts. Although picture presence and ease of anaphor resolution significantly improved comprehension of the material, no evidence was found for an interaction of these factors. The results are interpreted as consistent both with dual code theory and with aspects of working memory management that do not involve anaphor resolution.     

Coping as a building mechanism to explain the unique association of affect and goal motivation with changes in affective states

Background and objectives: In this study, we examined the mediating role of university students’ coping strategies in the unique/additive influence of affective states and goal motivation on upward changes in affect during a midterm exam period. Design: Using a short-term prospective design, key assumptions from the self-concordance model and the broaden-and-build theory were drawn upon to determine whether coping strategies are influenced by goal motivation and affective states, while also subsequently influencing short-term changes in affective states during a semester. Method: A sample of 272 students (79% females and 21% males) participated in a study in which they completed questionnaires twice during the semester. Results: Results of structural equation modeling, using a true latent change approach, have generally supported our hypotheses. Positive affective states and autonomous goal motivation prospectively predicted task-oriented coping which, in turn, was associated with increases in positive affect. Negative affective states and controlled goal motivation prospectively predicted disengagement-oriented coping which, in turn, was associated with increases in negative affect. Conclusion: Coping partially mediates the unique association of affect and goal motivation with changes in affective states of university students.     

Alexithymia and the automatic processing of affective information: Evidence from the affective priming paradigm

In Study 1, we examined the moderating impact of alexithymia (i.e., a difficulty identifying and describing feelings to other people and an externally oriented cognitive style) on the automatic processing of affective information. The affective priming paradigm was used, and lower priming effects for high alexithymia scorers were observed when congruent (incongruent) pairs involving nonverbal primes (angry face) and verbal target were presented. The results held after controlling for participants' negative affectivity. The same effects were replicated in Studies 2 and 3, with trait anxiety and depression entered as additional covariates. In Study 3, no moderating impact of alexithymia was found for verbal-facial pairs suggesting that the results cannot be merely explained in terms of transcoding limitations for high alexithymia scorers. Overall, the present results suggest that alexithymia could be related to a difficulty in processing and automatically using high arousal emotional information to respond to concomittant behavioural demands.     

A priori entailment and conceptual analysis: Making room for type-C physicalism 1

According to pancomputationalism, everything is a computing system. In this paper, I distinguish between different varieties of pancomputationalism. I find that although some varieties are more plausible than others, only the strongest variety is relevant to the philosophy of mind, but only the most trivial varieties are true. As a side effect of this exercise, I offer a clarified distinction between computational modelling and computational explanation.     

Eliciting positive,negative and mixed emotional states: A film library for affective scientists

We describe the creation of a film library designed for researchers interested in positive (amusing), negative (repulsive), mixed (amusing and repulsive) and neutral emotional states. Three hundred 20- to 33-second film clips videotaped by amateurs were selected from video-hosting websites and screened in laboratory studies by 75 female participants on self-reported amusement and repulsion (Experiments 1 and 2). On the basis of pre-defined cut-off values, 51 positive, 39 negative, 59 mixed and 50 neutral film clips were selected. These film clips were then presented to 411 male and female participants in a large online study to identify film clips that reliably induced the target emotions (Experiment 3). Depending on the goal of the study, researchers may choose positive, negative, mixed or neutral emotional film clips on the basis of Experiments 1 and 2 or Experiment 3 ratings.     

Drawing inferences about others' cognitions and affective reactions: A test of two models for representing affect

Abstract

To test divergent predictions of a “prototype” versus “affective tag” model for representing affect, children in the second and fourth grades listened to 10 sentences on-5 situational themes, with each theme being presented in an active version and a role-reversed version. Subjects made inferences about the story target's affective reactions or cognitions about these themes. Inferences about affective reactions were drawn more quickly than inferences about cognitions. For all inferences, the second, role-reversed presentation of a theme led to shorter response latencies. Responses were categorised into one of five response categories (Affect, Evaluation, Attribution, Script, and Reiteration). Although inferences about affect predominantly cited affect and inferences about cognitions tended not to cite affect, there was considerable response overlap so that affective inferences occasionally cited cognitions and cognitive inferences occasionally cited affect. The pattern of findings supports a prototype model rather than an affective tag model for the representation of affect.     

Non-selective lexical access in bilinguals is spontaneous and independent of input monitoring: Evidence from eye tracking

Language non-selective lexical access in bilinguals has been established mainly using tasks requiring explicit language processing. Here, we show that bilinguals activate native language translations even when words presented in their second language are incidentally processed in a nonverbal, visual search task. Chinese–English bilinguals searched for strings of circles or squares presented together with three English words (i.e., distracters) within a 4-item grid. In the experimental trials, all four locations were occupied by English words, including a critical word that phonologically overlapped with the Chinese word for circle or square when translated into Chinese. The eye-tracking results show that, in the experimental trials, bilinguals looked more frequently and longer at critical than control words, a pattern that was absent in English monolingual controls. We conclude that incidental word processing activates lexical representations of both languages of bilinguals, even when the task does not require explicit language processing.     

Masked affective priming by name letters: Evidence for a correspondence of explicit and implicit self-esteem

In an affective priming experiment (N = 60), participants’ initials were used as masked primes. We found a significant priming effect (denoting positivity of the personal initials) if personal initials (compared to yoked participants’ initials) were followed by other-relevant positive or negative targets (e.g., honest, cruel). For possessor-relevant targets (e.g., healthy, lonely), there was no main effect of priming. However, this priming index positively correlated with explicit self-esteem. For participants with high self esteem, a positive effect was found, whereas for participants with low self-esteem, a negative effect was found.     

Divided attention between lyrics and tunes of operatic songs: Evidence for independent processing

Excerpts from French operatic songs were used to evaluate the extent to which language and music compete for processing resources. Do these two dimensions conflict? Are they integrated into a single percept? Or are they independent? The final word of each excerpt was either semantically congruous or incongruous relative to the prior linguistic context and was sung either in or out of key. Participants were asked to detect either the semantic or the melodic incongruity (single task) or both (dual task). We predicted a dual-task deficit if these tasks conflicted and no deficit if they were either independent or integrated. In order to distinguish between these last two outcomes, trial-by-trial contingency analyses were also computed, predicting no correlation if the tasks were conflicting or independent, a positive correlation under the assumption of integration and a negative correlation if dividing attention is impossible. Our results show similar levels of performance in single and dual tasks and no correlation between dual-task judgments, thus suggesting that semantic and melodic aspects of language are processed by independent systems. In addition, a comparison between musicians and nonmusicians shows that these conclusions are independent of musical expertise.     

The Politicization of Migrants: Further Evidence that Politicized Collective Identity is a Dual Identity

The article examines the role of collective identification processes in the politicization of Russian migrants in Germany. Building on the assumption that politicized collective identity (PCI) is a dual identity, the authors predicted and found that dual identification as both Russian and German was positively related to politicization among members of the Russian minority in Germany. This relationship held up even when the influences of several sociodemographic variables, past political activity, and other forms of collective identification were statistically controlled. In addition, perceived maltreatment of Russian migrants in Germany moderated the relationship between dual identification and politicization in keeping with the theoretical assumption that the development of PCI presupposes high awareness of shared grievances. Finally, dual identification was unrelated to acceptance of political violence, but positively related to self‐restriction to peaceful political means. The constructive role of politicization driven by dual identification in social integration is discussed.     

Evidence for independent processing of subjective contour brightness and sharpness.

Subjective contours have been of considerable interest because of their importance to theories and physiological models of form perception. In particular, they have recently been characterized as the result of magnocellular cortical processing. There is, however, a paucity of parametric data relating to basic psychophysical parameters in this field. Two experiments are reported in which the roles of subjective contour size, retinal eccentricity, and flicker rate in subjective contour salience were investigated. Eleven observers estimated subjective contour magnitude using an Ehrenstein configuration. Configurations ranging in size from 0.25 to 3 deg were presented to three retinal loci (fovea, 2 deg, and 4 deg) at flicker rates ranging from 5 to 15 Hz. Subjective contour brightness and distinctness were measured separately. Brightness was greatest at a subjective contour size of about 1.25 deg, at flicker rates of 5-7 Hz, and at 3 deg peripheral for all flicker rates and all but the smallest stimulus sizes. Distinctness decreased with eccentricity and flicker, but remained high at small diameters (thus implicating spatially sensitive mechanisms). Taken together, the results support a magnocellular processing of subjective contours with respect to brightness, but also suggest that there is a parvocellular contribution to subjective contour sharpness.
