Approach, avoidance, and self-regulatory conflict: An individual differences perspective

Four studies involving 230 undergraduates examined the interactive effects of dispositional approach and avoidance, as manifest in the traits of extraversion and neuroticism. Participants who were high in both traits or low in both traits exhibited less assertive knocking behavior (Study 1), had difficulties refraining from blinking (Study 2), and displayed more anxious behavior during a mental health interview (Study 3). Study 4 tested the idea that such extraversion by neuroticism interactions might be associated with difficulties in recognizing and responding to goal-relevant stimuli. Results involving a go/no go task confirmed this hypothesis. In total, the results highlight the manner in which the co-activation of dispositional motives related to approach and avoidance can compromise effective self-regulation.     

Two routes for activation in the priming of categorical coordinates

The authors operationalized category priming as participants' recognition facilitation of nonstudied, low semantically similar exemplars by studied exemplars in a category. The existing literature either does not examine the effect of studied exemplars on nonstudied exemplars in a category or fails to show an appreciable amount of category priming. In 2 experiments, the authors demonstrated a unique process to account for the category priming effect and distinguish it from the semantic priming effect, facilitation of semantically similar exemplars, in the context of a category. In Experiment 1A, the authors used a multidimensional scaling technique to examine participants' internal structure of different categories. In Experiment 1B, the authors used a lexical decision task that used these internal structures to show that semantic encoding of category exemplars causes activation of existing category knowledge in memory. Consequently, participants easily recognized nonstudied, low semantically similar exemplars in a category. However, recognition facilitation between high semantically similar exemplars did not require category knowledge activation.     

Bringing out the agreeableness in everyone: Using a cognitive self-regulation model to reduce aggression

Research has shown that those individuals high in agreeableness recruit helpful thoughts in hostile contexts, presumably in the service of controlling aggressive behavior. The present experiment follows from such work, but importantly does so in a manner seeking to support causal conclusions. Participants were randomly assigned to an experimental training condition, in which hostile prime words were followed by helpful target words, or to a control condition that did not involve such pairings. Those assigned to the experimental condition subsequently exhibited lower levels of aggression in a laboratory task. Additional considerations and findings support the potential involvement of self-regulation processes. In general terms, the experiment reveals that a brief cognitive manipulation targeting processes thought to underlie aggression control was in fact causally effective in reducing subsequent levels of aggressive behavior.     

Auditory memory can be object based

Identifying how memories are organized remains a fundamental issue in psychology. Previous work has shown that visual short-term memory is organized according to the object of origin, with participants being better at retrieving multiple pieces of information from the same object than from different objects. However, it is not yet clear whether similar memory structures are employed for other modalities, such as audition. Under analogous conditions in the auditory domain, we found that short-term memories for sound can also be organized according to object, with a same-object advantage being demonstrated for the retrieval of information in an auditory scene defined by two complex sounds overlapping in both space and time. Our results provide support for the notion of an auditory object, in addition to the continued identification of similar processing constraints across visual and auditory domains. The identification of modality-independent organizational principles of memory, such as object-based coding, suggests possible mechanisms by which the human processing system remembers multimodal experiences.     

The Difference Between Lonely Old Ladies and CCTV Cameras: A Response to Ryberg

This article considers the question of whether it is meaningful to speak of privacy rights in public spaces, and the possibility of such rights framing the basis for regulating or restricting the use of surveillance technologies such as closed circuit television (CCTV). In particular, it responds to a recent article by Jesper Ryberg that suggests that there is little difference between being watched by private individuals and CCTV cameras, and instead argues that state surveillance is qualitatively different from (and more problematic than) surveillance by ‘lonely old ladies’.

Guarding against hostile thoughts: trait anger and the recruitment of cognitive control

Trait anger is a robust predictor of the angry and aggressive response to hostile situational input, but it is important to better understand the mechanisms underlying this dimension of personality. The present two studies (total N=106) examined the possibility that individuals low in trait anger systematically recruit cognitive control resources within hostile contexts. These resources would likely be useful in facilitating emotion regulation operations. In support of this cognitive control framework, Experiment 1 found that low (but not high) trait anger individuals exhibited superior response-switching abilities in a hostile stimulus context. Experiment 2 conceptually replicated this pattern using a different cognitive control measure related to flanker interference effects. The convergence of findings across studies provides one likely mechanism for the reduced levels of reactivity at low levels of trait anger. Findings are discussed in relation to broader theories of trait anger and emotion regulation.     

It all sounds the same to me: Sequential ERP and behavioral effects during pitch and harmonicity judgments

The representation of complex sounds was examined by comparing both behavioral and event-related brain potentials (ERPs) to the change or repetition of fundamental frequency (f0) and harmonicity. In the pitch task, participants were asked to categorize the incoming stimulus as either low or high, regardless of harmonicity, and in the harmonicity task, participants indicated whether the stimulus was tuned or mistuned, regardless of pitch. Over three experiments, participants were faster in responding to pitch than to harmonicity. As a result of this asymmetry, behavioral and ERP data showed that irrelevant changes in harmonicity had little impact on performance during the pitch task, whereas harmonicity judgments were impeded by irrelevant changes in f0. These data are consistent with both general horse-race accounts of processing and specific accounts of mistuning detection that posit prior f0 registration. In addition, ERP components N2 and P3 were modulated by both intertrial contingency and task instructions, revealing the further influence of top-down mechanisms on concurrent sound segregation.     

A Certain Kind of Trinity: Dependence, Substance, Explanation

The main contribution of this paper is a novel account of ontological dependence. While dependence is often explained in terms of modality and existence, there are relations of dependence that slip through the mesh of such an account. Starting from an idea proposed by Jonathan Lowe, the article develops an account of ontological dependence based on a notion of explanation; on its basis, certain relations of dependence can be established that cannot be accounted by the modal-existential account. Dependence is only one of two main topics of this paper, for it is approached via a discussion of the category of substance. On a traditional view, substances can be characterised as independent entities. Before the background of a modal-existential account of dependence, this idea appears problematic. The proposed notion of explanatory dependence is shown to vindicate the traditional approach to substance.
