Observing anger and aggression among preadolescent girls and boys: ethical dilemmas and practical solutions

To understand how children manage anger and engage in various forms of aggression, it is important to observe children responding to peer provocation. Observing children's anger and aggression poses serious ethical and practical challenges, especially with samples of older children and adolescents. This article describes 2 laboratory methods for observing children's responses to peer provocation: 1 involves participants playing a game with a provoking child actor, and the other involves a pair of close friends responding to an actor posing as a difficult play partner. Both methods are described in detail, ethical safeguards are discussed, and evidence is presented to show that children understand their research rights in these types of investigations.     

Contribution of somesthetic cues to the perception of body orientation and subjective visual vertical

Without relevant visual cues, the subjective visual vertical (SVV) is biased in roll-tilted subjects toward the body axis (Aubert or A-effect). This study focused on the role of the somatosensory system with respect to the SVV and on whether somesthetic cues act through the estimated body tilt. The body cast technology was used to obtain a diffuse tactile stimulation. An increased A-effect was expected because of a greater underestimation of the body position in the body cast. Sixteen subjects placed in a tilt chair were rolled sideways from 0 degrees to 105 degrees. They were asked to verbally indicate their subjective body position and then to adjust a luminous line to the vertical under strapped and body cast conditions. Results showed a greater A-effect (p < .001) but an overestimation of the body orientation (p < .01) in the body cast condition for the higher tilt values (beyond 60 degrees). Since the otolith organs produced the same gravity response in both conditions, errors were due to a change in somesthetic cues. Visual and postural errors were not directly related (no correlation). However, the angular distance between the apparent body position and the SW remained stable, suggesting that the change in somatosensory pattern inputs has a similar impact on the cognitive processes involved in assessing the perception of external space and the sense of self-position.     

The Silent Treatment? Changes in patient emotional expression after silence

Psychotherapy can be an emotionally laden conversation, where both verbal and nonverbal interventions may impact the therapeutic process. Prior research has postulated mixed results regarding how clients emotionally react following a silence after the therapist is finished talking, potentially due to studying a limited range of silences with primarily qualitative and self-report methodologies. A quantitative exploration may illuminate new findings. Utilising research and automatic data processing from the field of linguistics, we analysed the full range of silence lengths (0.2–24.01 s), and measures of emotional expression—vocally encoded arousal and emotional valence from the works spoken—of 84 audio recordings of Motivational Interviewing sessions. We hypothesised that both the level and the variance of client emotional expression would change as a function of silence length; however, due to the mixed results in the literature, the direction of emotional change was unclear. We conducted a multilevel linear regression to examine how the level of client emotional expression changed across silence length, and an ANOVA to examine the variability of client emotional expression across silence lengths. Results of both analyses indicated that as silence length increased, emotional expression largely remained the same. Broadly, we demonstrated a weak connection between silence length and emotional expression, indicating no persuasive evidence that silence leads to client emotional processing and expression.     

Olfactory discrimination of individual littermates in rats (Rattus norvegicus)

Adult male rats (Rattus norvegicus) were trained in a Y-maze to discriminate the presence of a littermate from its absence. Transfer of training in subsequent tests indicated that (a) the animals were capable of distinguishing among individuals when relatedness and familiarity were held constant, (b) this ability was not due to training, and (c) their performance was based solely on odor cues. The results are discussed in relation to social behavior in rats.     

Multicultural perspectives on suicide

Cultural differences exist as to suicide rates, suicide attempts, suicide attitudes such as acceptability, and appropriate treatment of suicide. Although suicide has been studied cross-nationally to highlight cross-cultural differences, the nuances of suicide among racioethnic groups within the United States have been at times been overlooked. The present article discusses suicide among the four (African American, Hispanic American, Native American, Asian American) most populous minority sociopolitical groups in the United States, and makes culture-specific recommendations for treatment and research.     

Top Ten Pressing Questions About the Development of Emotion Regulation

The papers in this special issue highlight the diversity of methods used to study the development of emotion regulation, and the substantial progress that has been made in understanding how children learn to manage strong emotions. This commentary poses 10 questions that focus on how developmental psychologists conceptualize emotions and regulation, measure emotions in research, and understand the interplay of individual and contextual variables. The discussion here outlines issues to guide future work; answers to these substantial questions will require much additional research.
