Cross-cultural similarities in category structure

Categories, as mental structures, are more than simply sums of property frequencies. A number of recent studies have supported the view that the properties of categories may be organised along functional lines and possibly dependency structures more generally. The study presented here investigates whether earlier findings reflect something unique in the English language/North American culture or whether the functional structuring of categories is a more universal phenomenon. A population of English-speaking Americans was compared to a population of Cantonese-speaking Hong Kong Chinese. The findings clearly support the view that functional influences on category centrality are universal (or at least common to Cantonese-speaking Hong Kong Chinese and English-speaking Americans), albeit with specific cross-cultural/cross-linguistic group differences in the particular properties that are considered central to categories.     

Towards an Understanding of Nurturing and Restraining Relational Patterns in School Communities

This study aimed to understand the nature of nurturing and restraining relationships in a school communiy. The inquiry entailed a single instrumental case study of a selected school community in a semi-urban context in South Africa. Participants were learners (n=720), teachers (n=33) and administrative and terrain staff members (N=8) as well as two parents. Data on participants' perceptions of relationships in the school community were collected using work sessions/nominal group techniques, visual representations, and focus group interviews. Thematic analysis of the data revealed connectedness, respect, care and transparent communication as aspects that nurture relationships. Limited connectedness between people, the abuse of power, shifting of responsibility and disrespect for one another were revealed as aspects that restrain relationships.     

The fate of unattended stimuli and emotional habituation: Behavioral interference and cortical changes

The interference produced by the viewing of emotional distractors has been interpreted as evidence that emotional cues are processed in a fairly mandatory fashion, and that they divert attention from the primary ongoing task. However, few studies have examined how behavioral emotional interference varies with repeated presentation of the same emotional distractors. In two experiments, while participants were engaged in a parity judgment task, we investigated the effects of repetition of task-irrelevant emotional pictures, as reflected in both behavioral interference (Experiments 1 and 2) and neural activity (Experiment 2). Both experiments showed that the slowing of reaction times that was observed when viewing emotional, compared to neutral, scenes disappeared after only a few repetitions, suggesting diminished attention allocation to repeated emotional pictures. Conversely, in Experiment 2, neural correlates of picture processing revealed that the late positive potential (LPP) amplitude continued to be enhanced for emotional, compared to neutral, distractors despite picture repetition and the presence of a concurrent task. Altogether, these findings suggest that while evaluative processes are mandatory, and continue to engage cortico-limbic appetitive and defensive systems even after massive repetition, as suggested by the affective modulation of the LPP, attentional processes are not necessary after several repetitions of the same stimulus, as indicated by the rapid decline of behavioral emotional interference.     

Cultural identity in Siberia and in analytical practice

This paper discusses the main features of Siberian identity formed throughout the historical development of Siberia under the influence of social, economic, geographical, climatic, and other factors. Siberian cultural identity is closely connected with the mythology and ancient religion of the indigenous peoples of Siberia – shamanism, whose rituals, images, symbols, and motifs are often manifested in the clients’ dreams. Following an in‐depth study of Siberian history and culture, I formulate a complex of homelessness rooted in a deep collective trauma that left its imprint on people’s psyche. Three clinical cases presented in the paper reveal a deep relationship between cultural complexes and collective traumas on the one hand, and individual complexes and traumas, on the other. My psychotherapeutic practice shows that a client’s awareness of their history and culture brings them closer to the meaning and source of their suffering, which, in turn, helps them find their own way of individuation, rather than relive the transgenerational trauma of their ancestors.     

The gender effect in 3D-Mental-rotation performance with familiar and gender-stereotyped objects – a study with elementary school children

The study examined the influence of gender-stereotyped stimuli rotated in depth on children’s mental-rotation performance. Participants included 321 elementary school children who completed three-dimensional mental-rotation tasks with either male- or female-stereotyped stimuli (M-MRT-3D/F-MRT-3D). Results suggest that in-depth tasks are very difficult for second graders. No gender effect was found in the mental-rotation performance of 7- to 9-year-old children; however, task understanding indicates gender differences. For fourth graders, a significant interaction of gender and stimulus type could be demonstrated. Furthermore, results indicate that fourth-grade boys tend to guess more often in tasks with stimuli consistent to the respective own gender. In addition, regression analyses showed that next to grade and perceptual speed, the perceived level of stimulus familiarity predicted performance. Considering a possible link between dimensionality and familiarity, the influence of the gender-stereotyped stimuli on children’s confidence and task understanding as well as on transformational processes and strategy efficiency is discussed.     

Distance stability analysis in multidimensional scaling using the jackknife method

Stability or sensitivity analysis is an important topic in data analysis that has received little attention in the application of multidimensional scaling (MDS), for which the only available approaches are given in terms of a coordinate‐based analytical jackknife methodology. Although in MDS the prime interest is in assessing the stability of the points in the configuration, this methodology may be influenced by imprecisions resulting from the inherently necessary Procrustes method. This paper proposes an analytical distance‐based jackknife procedure to study stability and cross‐validation in MDS in terms of the jackknife distances, which is not influenced by the Procrustes method. For each object, the corresponding jackknife estimated points are considered as naturally clustered points, and stability and cross‐validation are analysed in terms of the MDS distances arising from the jackknife procedure, on the basis of a weighted cluster‐MDS algorithm. A jackknife‐relevant configuration is also proposed for cross‐validation in terms of coordinates, in a cluster‐MDS framework.     

Emotion perception from a componential perspective

The common conceptual understanding of emotion is that they are multi-componential, including subjective feelings, appraisals, psychophysiological activation, action tendencies, and motor expressions. Emotion perception, however, has traditionally been studied in terms of emotion labels, such as “happy”, which do not clearly indicate whether one, some, or all emotion components are perceived. We examine whether emotion percepts are multi-componential and extend previous research by using more ecologically valid, dynamic, and multimodal stimuli and an alternative response measure. The results demonstrate that observers can reliably infer multiple types of information (subjective feelings, appraisals, action tendencies, and social messages) from complex emotion expressions. Furthermore, this finding appears to be robust to changes in response items. The results are discussed in light of their implications for research on emotion perception.
