Social Anxiety and Anger Identification: Bubbles Reveal Differential Use of Facial Information With Low Spatial Frequencies

ABSTRACT— We investigated the facial information that socially anxious and nonanxious individuals utilize to judge emotions. Using a reversed-correlation technique, we presented participants with face images that were masked with random bubble patterns. These patterns determined which parts of the face were visible in specific spatial-frequency bands. This masking allowed us to establish which locations and spatial frequencies were helping participants to successfully discriminate angry faces from neutral ones. Although socially anxious individuals performed as well as nonanxious individuals on the emotion-discrimination task, they did not utilize the same facial information for the task. The fine details (high spatial frequencies) around the eyes were discriminative for both groups, but only socially anxious participants additionally processed rough configural information (low spatial frequencies).     

Time–space synaesthesia – A cognitive advantage?

Is synaesthesia cognitively useful? Individuals with time–space synaesthesia experience time units (such as months of the year) as idiosyncratic spatial forms, and report that these forms aid them in mentally organising their time. In the present study, we hypothesised that time–space synaesthesia would facilitate performance on a time-related cognitive task. Synaesthetes were not specifically recruited for participation; instead, likelihood of time–space synaesthesia was assessed on a continuous scale based on participants’ responses during a semi-structured interview. Participants performed a month-manipulation task, which involved naming every second month or every third month in reverse-chronological order, beginning and ending with a target month. Using hierarchical multiple regression, we found that time–space synaesthesia corresponded with faster performance on both versions of the task. We propose that time–space synaesthesia may expedite the cognitive manipulation of time-based information. Our results also indicate that synaesthesia is far less unusual than widely believed.     

Comparison of methods for constructing confidence intervals of standardized indirect effects

Mediation models are often used as a means to explain the psychological mechanisms between an independent and a dependent variable in the behavioral and social sciences. A major limitation of the unstandardized indirect effect calculated from raw scores is that it cannot be interpreted as an effect-size measure. In contrast, the standardized indirect effect calculated from standardized scores can be a good candidate as a measure of effect size because it is scale invariant. In the present article, 11 methods for constructing the confidence intervals (CIs) of the standardized indirect effects were evaluated via a computer simulation. These included six Wald CIs, three bootstrap CIs, one likelihood-based CI, and the PRODCLIN CI. The results consistently showed that the percentile bootstrap, the bias-corrected bootstrap, and the likelihood-based approaches had the best coverage probability. Mplus, LISREL, and Mx syntax were included to facilitate the use of these preferred methods in applied settings. Future issues on the use of the standardized indirect effects are discussed.     

The Burden of Proof and Its Role in Argumentation

The notion of “the burden of proof” plays an important role in real-world argumentation contexts, in particular in law. It has also been given a central role in normative accounts of argumentation, and has been used to explain a range of classic argumentation fallacies. We argue that in law the goal is to make practical decisions whereas in critical discussion the goal is frequently simply to increase or decrease degree of belief in a proposition. In the latter case, it is not necessarily important whether that degree of belief exceeds a particular threshold (e.g., ‘reasonable doubt’). We explore the consequences of this distinction for the role that the “burden of proof” has played in argumentation and in theories of fallacy.     

Visual object affordances: object orientation

Five experiments systematically investigated whether orientation is a visual object property that affords action. The primary aim was to establish the existence of a pure physical affordance (PPA) of object orientation, independent of any semantic object-action associations or visually salient areas towards which visual attention might be biased. Taken together, the data from these experiments suggest that firstly PPAs of object orientation do exist, and secondly, the behavioural effects that reveal them are larger and more robust when the object appears to be graspable, and is oriented in depth (rather than just frontally) such that its leading edge appears to point outwards in space towards a particular hand of the viewer.     

Successfully challenging fundamentalist beliefs results in increased death awareness

Terror management theory argues that human understanding of mortality creates an existential anxiety that must be kept under constant control. Defenses—such as beliefs that provide permanence, predictability, and meaning—are erected whose function is in part to keep thoughts about death as far removed from consciousness as possible. The current study investigated the defensive function of Christian fundamentalist belief in managing death-awareness. The general hypothesis of the study is that challenges to such beliefs undermine one’s ability to control cognitions related to mortality. More specifically, it was hypothesized that successful challenges to this form of religious belief would make death-related cognitions more accessible to consciousness. Self-identified Christians, both fundamentalists and non-fundamentalists, encountered material that challenged the fundamentalist belief that the Christian Bible is free of inconsistencies and contradictions. Consistent with expectations, under these conditions higher levels of accessibility of death-related cognition were found among fundamentalist Christians, but not their non-fundamentalist counterparts.     

Eye movements as direct tests of the GO model for the missing-letter effect

When asked to detect target letters while reading a text, participants miss more letters in frequently occurring function words than in less frequent content words. To account for this pattern of results, known as the missing-letter effect, Greenberg, Healy, Koriat, and Kreiner proposed the guidance-organization (GO) model, which integrates the two leading models of the missing-letter effect while incorporating innovative assumptions based on the literature on eye movements during reading. The GO model was evaluated by monitoring the eye movements of participants while they searched for a target letter in a continuous text display. Results revealed the usual missing-letter effect, and many empirical benchmark effects in eye movement literature were observed. However, contrary to the predictions of the GO model, response latencies were longer for function words than for content words. Alternative models are discussed that can accommodate both error and response latency data for the missing-letter effect.     

The role of visual attention in action priming

It has been demonstrated that the task-irrelevant left-right orientation of an object is capable of facilitating left-right-hand responses when the object is orientated towards the responding hand. We investigated the role of attention in this orientation effect. Experiment 1 showed that object orientation facilitates responses of the hand that is compatible with the object's orientation, despite the entire object being irrelevant. However, when a task-relevant fixation point was displayed over the prime object in Experiment 2, the effect was not observed. Together Experiments 1 and 2 suggest that the orientation information of viewed objects primes the action selection processes even when the object is irrelevant, but only when attention is not allocated to a competing stimulus during the prime presentation. Experiment 3 suggested that the elimination of the effect in Experiment 2 could not be attributed to the elimination of an attentional shift to the graspable part of the prime. Finally, Experiment 4 showed that object orientation can evoke an abstract response code, influencing the selection of finger responses.     

When Rules Go Awry: A Single Case Analysis of Cycle Rage

On a sunny Sunday afternoon in 2012 a conflict arose between two men riding a popular mountain biking track in New Zealand. The bulk of this was filmed from a helmet-mounted action camera, facilitating a single case analysis of the transition from an everyday trouble to an unexpected violent ending. The two riders come across each other travelling downhill at speed on a narrow track. Unease quickly develops for the camera-clad rider wants to pass the rider in front, but except for an intriguing and brief interlude, the first rider will not let the other pass. The second rider grows frustrated, progressing to tailgate the ‘slower’ rider, in the midst of which he invokes a rule of mountain biking conduct. The reflexive implications of the rule-invocation need to be seen to be believed. The video is used as data to get close to such seeing, and despite some limitations, we can see a clear trajectory where the rule significantly contributes to a moment of phenomenological salience. Thereafter, it becomes witnessably relevant to the conflict that develops.
