Contributions of facial expressions and body language to the rapid perception of dynamic emotions

Correctly perceiving emotions in others is a crucial part of social interactions. We constructed a set of dynamic stimuli to determine the relative contributions of the face and body to the accurate perception of basic emotions. We also manipulated the length of these dynamic stimuli in order to explore how much information is needed to identify emotions. The findings suggest that even a short exposure time of 250 milliseconds provided enough information to correctly identify an emotion above the chance level. Furthermore, we found that recognition patterns from the face alone and the body alone differed as a function of emotion. These findings highlight the role of the body in emotion perception and suggest an advantage for angry bodies, which, in contrast to all other emotions, were comparable to the recognition rates from the face and may be advantageous for perceiving imminent threat from a distance.     

Learning about Probability from Text and Tables: Do Color Coding and Labeling through an Interactive‐user Interface Help?

Learning from visual representations is enhanced when learners appropriately integrate corresponding visual and verbal information. This study examined the effects of two methods of promoting integration, color coding and labeling, on learning about probabilistic reasoning from a table and text. Undergraduate students (N = 98) were randomly assigned to learn about probabilistic reasoning from one of 4 computer‐based lessons generated from a 2 (color coding/no color coding) by 2 (labeling/no labeling) between‐subjects design. Learners added the labels or color coding at their own pace by clicking buttons in a computer‐based lesson. Participants' eye movements were recorded while viewing the lesson. Labeling was beneficial for learning, but color coding was not. In addition, labeling, but not color coding, increased attention to important information in the table and time with the lesson. Both labeling and color coding increased looks between the text and corresponding information in the table. The findings provide support for the multimedia principle, and they suggest that providing labeling enhances learning about probabilistic reasoning from text and tables.

Triggering Safe Attachment Waves to Foster Healing in International Protection-Seeking Environments

ABSTRACT

The present article aims to illustrate how healing for children and families seeking international protection is preceded by the promotion and establishment of safe attachment interactions not only with minors and their caregivers but also with any stakeholder involved in their environment. This is a recognition of both the security chains a therapist can trigger, and how relational safety and trust constitute a necessary condition and are actually interventions – to heal both from past and present trauma derived from the unstable and uncertain pre and post-migration experiences families and children go through. Suggestions are provided on how mental health professionals can repair and enhance such eroded safety and trust by intervening inside and outside the therapy room, and on how Accelerated Experiential Dynamic Psychotherapy may constitute a valuable framework to inform our clinical work in this scenario.     

A Sociocultural Approach to Narcissism: The Case of Modern China

Using large Internet samples, we examined the possible influence of sociodemographic factors on the Chinese self‐concept and in particular, on the level of narcissism. We found that (i) younger persons are more narcissistic than older ones; (ii) persons from higher socioeconomic classes are more narcissistic than those from lower socioeconomic classes; (iii) persons from only‐child families are more narcissistic than those from families with multiple children; (iv) persons from urban areas are more narcissistic than those from rural areas; and (v) individualistic values are predictive of individual differences in narcissism. The findings suggest that sociocultural changes contribute to the rise of narcissism in China. Copyright © 2011 John Wiley & Sons, Ltd.     

Structure and function of auditory cortex: music and speech

We examine the evidence that speech and musical sounds exploit different acoustic cues: speech is highly dependent on rapidly changing broadband sounds, whereas tonal patterns tend to be slower, although small and precise changes in frequency are important. We argue that the auditory cortices in the two hemispheres are relatively specialized, such that temporal resolution is better in left auditory cortical areas and spectral resolution is better in right auditory cortical areas. We propose that cortical asymmetries might have developed as a general solution to the need to optimize processing of the acoustic environment in both temporal and frequency domains.     

Examining posttraumatic growth among Japanese university students

Abstract

To determine the underlying factor structure of the Japanese version of the Posttraumatic Growth Inventory (PTGI-J), a principal components analysis was performed on data from 312 Japanese undergraduate students who reported growth due to their most traumatic event within the last 5 years. Results showed the PTGI-J has high internal consistency and, of the original five factors reported by Tedeschi and Calhoun (1996), three were replicated: Relating to Others, New Possibilities, Personal Strength, and a fourth factor integrating Spiritual Change and Appreciation of Life emerged. There were neither gender differences nor relationships with time since trauma. PTGI-J scores were positively associated with posttraumatic symptoms and correlated with type of traumatic event experienced. These results and future directions are discussed from a cross-cultural viewpoint.     

Of hissing snakes and angry voices: human infants are differentially responsive to evolutionary fear‐relevant sounds

Adult humans demonstrate differential processing of stimuli that were recurrent threats to safety and survival throughout evolutionary history. Recent studies suggest that differential processing of evolutionarily ancient threats occurs in human infants, leading to the proposal of an inborn mechanism for rapid identification of, and response to, evolutionary fear‐relevant stimuli. The current study provides novel data in support of this proposal, showing for the first time that human infants differentially process evolutionary threats presented in the auditory modality. Sixty‐one 9‐month‐olds listened to evolutionary fear‐relevant, modern fear‐relevant, and pleasant sounds, while their heart rate, startle, and visual orienting behaviours were measured. Infants demonstrated significantly enhanced heart rate deceleration, larger eye‐blinks, and more visual orienting when listening to evolutionary fear‐relevant sounds compared to sounds from the other two categories. These results support the proposal that human infants possess evolved mechanisms for the differential processing of a range of ancient environmental threats.     

SES differences in language processing skill and vocabulary are evident at 18 months

This research revealed both similarities and striking differences in early language proficiency among infants from a broad range of advantaged and disadvantaged families. English‐learning infants (n = 48) were followed longitudinally from 18 to 24 months, using real‐time measures of spoken language processing. The first goal was to track developmental changes in processing efficiency in relation to vocabulary learning in this diverse sample. The second goal was to examine differences in these crucial aspects of early language development in relation to family socioeconomic status (SES). The most important findings were that significant disparities in vocabulary and language processing efficiency were already evident at 18 months between infants from higher‐ and lower‐SES families, and by 24 months there was a 6‐month gap between SES groups in processing skills critical to language development.     

Procedural Text Structure and Reader Perceptions and Performance

This research tested the relationship between text structural variables (on vs. off the causal chain, active vs. static information, and hierarchical structure) and reader perceptions, reading time, and true-false performance for procedural texts. Twenty-four college-age participants each read 3 procedural texts. As predicted, sentences that were (a) on the causal chain, (b) active, and (c) associated with task steps were read more slowly and judged to be more important (p < .05). The results were similar to those previously found with narratives, except for the hierarchical structure variable. Also as predicted, text differences were found such that as the variation in the type of information contained in the text increased, relationships with the structural variables increased.     

The Role of Short-Term Memory in Semantic Priming

Two theories of priming were compared: spreading activation theories, in particular ACT* (J. R. Anderson, 1983), and compound-cue theories (R. Ratcliff & G. McKoon, 1988). Whereas ACT* assumes that priming is a result of diffusing activation in long-term memory, compound-cue models suggest that priming results from a formation process of prime and target in short-term memory. Thirty-eight participants took part in a study that combined a digit span task with a double lexical decision task consisting of a prime and a target item. Digit span length (low, medium, and high) and prime type (related or unrelated word or nonword) were both within-subject variables. As expected, results showed significant priming effects. In favor of ACT*, no interaction between digit span length and prime type was found. Additionally, a nonword inhibition effect (unrelated versus nonword prime) was found, which was predicted by compound-cue theories. This finding is discussed in terms of the process interference and response competition hypotheses.
