The relationship between interpersonal perception and post-traumatic stress disorder-related functional impairment: a social relations model analysis

This study used Kenny's social relations model to examine the relationship between Post-Traumatic Stress Disorder-related impairment and interpersonal perceptions. Participants were 124 students who had previously completed the Post-traumatic Stress Diagnostic Scale as part of a larger study. After engaging in brief dyadic conversations with 3 other students, participants recorded perceptions of personality traits for themselves, their interaction partners and how they believed their partners saw them (metaperceptions). Results indicated that those with more severe post-traumatic stress disorder-related impairment saw themselves negatively and believed their interaction partners also viewed them negatively. However, these individuals were not seen differently by others, except that they were rated as less dependable. Our findings suggest that post-traumatic stress disorder is associated with negative beliefs about the self that may influence self-esteem and interpersonal relationships.     

Sweet-cheeks vs. pea-brain: embodiment,valence, and task all influence the emotional salience of language

Previous research has found that more embodied insults (e.g. numbskull) are identified faster and more accurately than less embodied insults (e.g. idiot). The linguistic processing of embodied compliments has not been well explored. In the present study, participants completed two tasks where they identified insults and compliments, respectively. Half of the stimuli were more embodied than the other half. We examined the late positive potential (LPP) component of event-related potentials in early (400–500?ms), middle (500–600?ms), and late (600–700?ms) time windows. Increased embodiment resulted in improved response accuracy to compliments in both tasks, whereas it only improved accuracy for insults in the compliment detection task. More embodied stimuli elicited a larger LPP than less embodied stimuli in the early time window. Insults generated a larger LPP in the late time window in the insult task; compliments generated a larger LPP in the early window in the compliment task. These results indicate that electrophysiological correlates of emotional language perception are sensitive to both top-down and bottom-up processes.     

Orthographic and phonological facilitation in speech production: new evidence from picture naming in Chinese

Picture naming is facilitated when a target picture (e.g. of a cat) is accompanied by a form-related context word (e.g. CAP) relative to an unrelated word (e.g. PEN). Because in alphabetic languages phonological and orthographic similarity are confounded, Chinese, a logographic language, has been employed to study these two effects in isolation. The results obtained suggest that the orthographic facilitation effect is localized at an earlier processing level than the phonological facilitation effect. In the present study we examine this issue again, using an experimental design in which the context words in the related and unrelated conditions are optimally matched. In contrast to the earlier studies Experiments 1 and 2 fail to show differences in the time course of the two context effects. Moreover, Experiment 3 provides direct evidence against an early, conceptual locus of orthographic facilitation. Our findings indicate that in Chinese language production both orthographically and phonologically related context words have their effect at the rather late level of word-form encoding.     

Morphological priming survives a language switch

In a long-lag morphological priming experiment, Dutch (L1)-English (L2) bilinguals were asked to name pictures and read aloud words. A design using non-switch blocks, consisting solely of Dutch stimuli, and switch-blocks, consisting of Dutch primes and targets with intervening English trials, was administered. Target picture naming was facilitated by morphologically related primes in both non-switch and switch blocks with equal magnitude. These results contrast some assumptions of sustained reactive inhibition models. However, models that do not assume bilinguals having to reactively suppress all activation of the non-target language can account for these data.     

RACE/A: an architectural account of the interactions between learning, task control, and retrieval dynamics

This article discusses how sequential sampling models can be integrated in a cognitive architecture. The new theory Retrieval by Accumulating Evidence in an Architecture (RACE/A) combines the level of detail typically provided by sequential sampling models with the level of task complexity typically provided by cognitive architectures. We will use RACE/A to model data from two variants of a picture-word interference task in a psychological refractory period design. These models will demonstrate how RACE/A enables interactions between sequential sampling and long-term declarative learning, and between sequential sampling and task control. In a traditional sequential sampling model, the onset of the process within the task is unclear, as is the number of sampling processes. RACE/A provides a theoretical basis for estimating the onset of sequential sampling processes during task execution and allows for easy modeling of multiple sequential sampling processes within a task.     

The nature of hemispheric specialization for prosody perception

Recent evidence suggests a relative right-hemispheric specialization for emotional prosody perception, whereas linguistic prosody perception is under bilateral control. It is still unknown, however, how the hemispheric specialization for prosody perception might arise. Two main hypotheses have been put forward. Cue-dependent hypotheses, on the one hand, propose that hemispheric specialization is driven by specialization for the non-prosody-specific processing of acoustic cues. The functional lateralization hypothesis, on the other hand, proposes that hemispheric specialization is dependent on the communicative function of prosody, with emotional and linguistic prosody processing being lateralized to the right and left hemispheres, respectively. In the present study, the functional lateralization hypothesis of prosody perception was systematically tested by instructing one group of participants to evaluate the emotional prosody, and another group the linguistic prosody dimension of bidimensional prosodic stimuli in a dichotic-listening paradigm, while event-related potentials were recorded. The results showed that the right-ear advantage was associated with decreased latencies for an early negativity in the contralateral hemisphere. No evidence was found for functional lateralization. These findings suggest that functional lateralization effects for prosody perception are small and support the structural model of dichotic listening.     

Defining greed

Although greed is both hailed as the motor of economic growth and blamed as the cause of economic crises, very little is known about its psychological underpinnings. Five studies explored lay conceptualizations of greed among US and Dutch participants using a prototype analysis. Study 1 identified features related to greed. Study 2 determined the importance of these features; the most important features were classified as central (e.g., self‐interested, never satisfied), whereas less important features were classified as peripheral (e.g., ambition, addiction). Subsequently, we found that, compared to peripheral features, participants recalled central features better (Study 3), faster (Study 4), and these central features were more present in real‐life episodes of greed (Study 5). These findings provide a better understanding of the elements that make up the experience of greed and provide insights into how greed can be manipulated and measured in future research.
