The Berlin Affective Word List Reloaded (BAWL-R)

The study presented here provides researchers with a revised list of affective German words, the Berlin Affective Word List Reloaded (BAWL-R). This work is an extension of the previously published BAWL (V?, Jacobs, & Conrad, 2006), which has enabled researchers to investigate affective word processing with highly controlled stimulus material. The lack of arousal ratings, however, necessitated a revised version of the BAWL. We therefore present the BAWL-R, which is the first list that not only contains a large set of psycholinguistic indexes known to influence word processing, but also features ratings regarding emotional arousal, in addition to emotional valence and imageability. The BAWL-R is intended to help researchers create stimulus material for a wide range of experiments dealing with the affective processing of German verbal material.     

The role of Theory of Mind in assessing cooperative intentions

Folk wisdom indicates that people vary in the extent to which they can assess others’ cooperative intentions. In two studies we investigated whether Theory of Mind (ToM), the ability to represent mental states of others, is related to accuracy in the recognition of cooperativeness. Participants completed a ToM task and were asked to assess either video clips of people playing a variation of a Prisoner’s Dilemma (PD) game (Study 1, N = 88), or photographs of people playing PD taken at the very moment when they were expressing a decision to cooperate or to defect (Study 2, N = 99). We found relationships between ToM and cooperative intention recognition only in Study 1, when participants were exposed to long versions of the video clips. In contrast to previous reports, participants in our samples did not score higher than chance in cooperativeness assessment except for Study 1 in the condition with short video clips. Our results question human expertise at identifying defectors and cooperators and do not provide clear support for an association between ToM and cooperativeness assessment. The findings are discussed from the perspective of an evolutionary arms race between interpreting and masking cooperative intentions.     

The best time to acquire new skills: age-related differences in implicit sequence learning across the human lifespan

Implicit skill learning underlies obtaining not only motor, but also cognitive and social skills through the life of an individual. Yet, the ontogenetic changes in humans' implicit learning abilities have not yet been characterized, and, thus, their role in acquiring new knowledge efficiently during development is unknown. We investigated such learning across the lifespan, between 4 and 85 years of age with an implicit probabilistic sequence learning task, and we found that the difference in implicitly learning high- vs. low-probability events--measured by raw reaction time (RT)--exhibited a rapid decrement around age of 12. Accuracy and z-transformed data showed partially different developmental curves, suggesting a re-evaluation of analysis methods in developmental research. The decrement in raw RT differences supports an extension of the traditional two-stage lifespan skill acquisition model: in addition to a decline above the age 60 reported in earlier studies, sensitivity to raw probabilities and, therefore, acquiring new skills is significantly more effective until early adolescence than later in life. These results suggest that due to developmental changes in early adolescence, implicit skill learning processes undergo a marked shift in weighting raw probabilities vs. more complex interpretations of events, which, with appropriate timing, prove to be an optimal strategy for human skill learning.     

Peer Victimization in Childhood and Internalizing Problems in Adolescence: A Prospective Longitudinal Study

Traumatic childhood experiences have been found to predict later internalizing problems. This prospective longitudinal study investigated whether repeated and intentional harm doing by peers (peer victimization) in childhood predicts internalizing symptoms in early adolescence. 3,692 children from the Avon Longitudinal Study of Parents and Children (ALSPAC), as well as their mothers and teachers, reported on bullying in childhood (7–10 years) and internalizing problems in early adolescence (11–14 years). Controlling for prior psychopathology, family adversity, gender and IQ, being a victim of bullying was associated with higher overall scores, as well as increased odds of scoring in the severe range (>90^th percentile) for emotional and depression symptoms. Victims were also more likely to show persistent depression symptoms over a 2-year period. These associations were found independent of whether mothers, teachers or the children reported on bullying. It is concluded that peer victimization in childhood is a precursor of both short-lived and persistent internalizing symptoms, underlining the importance of environmental factors such as peer relationships in the etiology of internalizing problems.     

Quantitative and Qualitative Research across Cultures and Languages: Cultural Metrics and their Application

Growing globalisation of the world draws attention to cultural differences between people from different countries or from different cultures within the countries. Notwithstanding the diversity of people’s worldviews, current cross-cultural research still faces the challenge of how to avoid ethnocentrism; comparing Western-driven phenomena with like variables across countries without checking their conceptual equivalence clearly is highly problematic. In the present article we argue that simple comparison of measurements (in the quantitative domain) or of semantic interpretations (in the qualitative domain) across cultures easily leads to inadequate results. Questionnaire items or text produced in interviews or via open-ended questions have culturally laden meanings and cannot be mapped onto the same semantic metric. We call the culture-specific space and relationship between variables or meanings a ’cultural metric’, that is a set of notions that are inter-related and that mutually specify each other’s meaning. We illustrate the problems and their possible solutions with examples from quantitative and qualitative research. The suggested methods allow to respect the semantic space of notions in cultures and language groups and the resulting similarities or differences between cultures can be better understood and interpreted.     

On‐Line Support and Resources for People Bereaved through Suicide: What Is Available?

The Internet is a potentially valuable source of information for the bereaved, but the current knowledge regarding the type and quality of online material on suicide bereavement is very limited. This study was designed to explore the types of online information and support available for people bereaved by suicide and the quality of such resources. Four popular Internet search engines were searched using terms related to suicide bereavement and support. Although a wide range of Internet resources exist for people bereaved by suicide, these resources may not meet basic quality standards. It is unknown who uses these sites, how such material is used, and whether it helps people to cope effectively with grief after suicide.     

Sedentary antlion larvae (Neuroptera: Myrmeleontidae) use vibrational cues to modify their foraging strategies

Learning abilities are exhibited by many animals, including insects. However, sedentary species are typically believed to have low capacities and requirements for learning. Despite this view, recent studies show that even such inconspicuous organisms as larval antlions, which employ an ambush predation strategy, are capable of learning, although their learning abilities are rather simple, i.e., limited to the association of vibrational cues with the arrival of prey. This study demonstrates, for the first time, that antlion larvae can use vibrational cues for complex modifications of their foraging strategies. Specifically, antlion larvae rapidly learn to differentiate between the vibrational cues associated with prey of different sizes, and they save resources by ignoring smaller prey in favour of larger, more energetically profitable prey. Moreover, antlion larvae can learn to associate vibrational cues with the loss of their prey, and they respond by burying their victims under the sand more often and more rapidly than do individuals with no opportunities to form such associations. These findings provide not only new insights into the cognitive abilities of animals but also support for the optimal foraging strategy concept, suggesting the importance of maximizing fitness output by balancing the costs and benefits of alternative foraging strategies.
