Threat-level-dependent manipulation of signaled body size: dog growls’ indexical cues depend on the different levels of potential danger

Body size is an important feature that affects fighting ability; however, size-related parameters of agonistic vocalizations are difficult to manipulate because of anatomical constraints within the vocal production system. Rare examples of acoustic size modulation are due to specific features that enable the sender to steadily communicate exaggerated body size. However, one could argue that it would be more adaptive if senders could adjust their signaling behavior to the fighting potential of their actual opponent. So far there has been no experimental evidence for this possibility. We tested this hypothesis by exposing family dogs (Canis familiaris) to humans with potentially different fighting ability. In a within-subject experiment, 64 dogs of various breeds consecutively faced two threateningly approaching humans, either two men or two women of different stature, or a man and a woman of similar or different stature. We found that the dogs’ vocal responses were affected by the gender of the threatening stranger and the dog owner’s gender. Dogs with a female owner, or those dogs which came from a household where both genders were present, reacted with growls of lower values of the Pitch–Formant component (including deeper fundamental frequency and lower formant dispersion) to threatening men. Our results are the first to show that non-human animals react with dynamic alteration of acoustic parameters related to their individual indexical features (body size), depending on the level of threat in an agonistic encounter.     

More or less: spontaneous quantity discrimination in the domestic cat

We examined spontaneous quantity discrimination in untrained domestic cats in three food choice experiments. In Experiment 1, we presented the cats with two different quantities of food in eight numerical combinations. Overall, the subjects chose the larger quantity more often than the smaller one, and significantly so when the ratio between the quantities was less than 0.5. In Experiment 2, we presented the cats with two pieces of food in four different size combinations. Again, subjects chose the larger piece above chance, although not in the combination where the largest item was presented. In Experiment 3, a subset of the cats was presented multiple times with two different quantities of food, which were hidden from view. In this case, the cats did not choose the larger quantity more often than the smaller one, suggesting that in the present experiments they mainly used visual cues when comparing quantities. We conclude that domestic cats are capable of spontaneously discriminating quantities when faced with different numbers or sizes of food items, and we suggest why they may not always be motivated to choose the larger quantity. In doing so, we highlight the advantages of testing spontaneous choice behavior, which is more likely to reflect animals’ everyday manner of responding than is the case when training them in order to test their absolute limits of performance which may not always coincide with their daily needs.     

Building Buddhism in England: The Flourishing of a Minority Faith Heritage

From the earliest days of Buddhism in Britain, individuals and communities have sought out buildings to provide locations where they might practise and teach Buddhism. In this paper, we focus on this neglected area of the study of minority faith traditions in Britain. Our research, which was commissioned by Historic England, examines how Buddhist communities have used buildings and what this tells us about how a minority tradition is initially established and how it subsequently changes and develops. In this context, we suggest that buildings are more than bricks and mortar and provide a richly rewarding analytical lens to tell stories about migration, socio-economic status, religious diversity and integration and the complexity of processes around secularisation and religious change, as well shifting policy agendas in the UK that have begun to take faith seriously. This contributes to deepening the picture of the migration and adaptation of Buddhism and Buddhist practice across the globe.     

Contextual repetition facilitates word learning via fast mapping

The current study explores whether contextual repetition during fast mapping facilitates word learning. Three-year-old children completed fast mapping and test trials using a touchscreen computer. For half of the children, the non-targets (competitors) repeated across learning trials and for other children there was no repetition. All children received the same test trials. Children who experienced contextual repetition, that is, children for whom the competitors repeated during the initial fast mapping task, demonstrated word learning. These data demonstrate that children's word learning is facilitated by the presence of extraneous yet predictable information in the initial fast mapping task.     

Mental health in Swedish children living in joint physical custody and their parents' life satisfaction: A cross‐sectional study

This study compared the psychological symptoms of 129 children in joint physical custody with children in single care and nuclear families, using a nationally representative 2011 survey of 1,297 Swedish children aged between four and 18 years. The outcome measure was the Strengths and Difficulties Questionnaire (SDQ) and its association with three dimensions of parental life satisfaction was investigated. Linear regression analyses showed higher SDQ‐scores for children in joint physical custody (B = 1.4, p < 0.001) and single care (B = 2.2, p < 0.001) than in nuclear families, after adjustment for socio‐demographic variables. The estimates decreased to 1.1 and 1.3, respectively, after being adjusted for parental life satisfaction ( p < 0.01). Our findings confirm previous research that showed lower symptom scores for children in nuclear families than children in single care and joint physical custody. Parental life satisfaction should be investigated further as a possible explanation of differences in symptom load between children in different living arrangements.     

The Conscientiousness Paradox: Cultural Mindset Shapes Competence Perception

Studies comparing personality across cultures have found inconsistencies between self‐reports and measures of national character or behaviour, especially on evaluative traits such as Conscientiousness. We demonstrate that self‐perceptions and other‐perceptions of personality vary with cultural mindset, thereby accounting for some of this inconsistency. Three studies used multiple methods to examine perceptions of Conscientiousness and especially its facet Competence that most characterizes performance evaluations. In Study 1, Mainland Chinese reported lower levels of self‐efficacy than did Canadians, with the country effect partially mediated by Canadian participants' higher level of independent self‐construal. In Study 2, language as a cultural prime induced similar effects on Hong Kong bilinguals, who rated themselves as more competent and conscientious when responding in English than in Chinese. Study 3 demonstrated these same effects on ratings of both self‐perceived and observer‐perceived competence and conscientiousness, with participants changing both their competence‐communicating behaviours and self‐evaluations in response to the cultural primes of spoken language and ethnicity of an interviewer. These results converge to show that self‐perceptions and self‐presentations change to fit the social contexts shaped by language and culture.

Beyond Similarities: Cross-Gender and Cross-Orientation Best Friendship in a Sample of Sexual Minority and Heterosexual Young Adults

The research investigates differences between heterosexual (n?=?714) and lesbian and gay men (n?=?386) young adults regarding best friendship patterns, well-being, and social anxiety. Based on data from a paper-pencil survey of 1,100 Italian young adults aged 18 to 26, this study underlines the importance of the best friend in young adults’ psychological adjustment, highlighting patterns of friendship in heterosexual and lesbian and gay men young adults. Overall, the majority of participants declared that they had best friends; in the total sample, significant differences were found between women and men, and between lesbian/gay men participants and heterosexual young adults. Lesbian and gay men participants reported more cross-gender best friendships than heterosexual participants did, as well as more cross-orientation best friendships. Gender differences were found only with regards to cross-gender friendships: gay men reported more cross-gender friendships than lesbians did, while heterosexual females reported a higher percentage of cross-gender best friendship than heterosexual males did. MANOVA analysis, only in the gay and lesbian sample, showed the effect of gender, cross-gender, and cross-orientation on well-being and social anxiety. For the well-being dimension, gay men participants with female best friends reported higher scores. In terms of social anxiety, lesbian and gay young adults with cross-gender and cross-orientation best friends reported lower levels of social anxiety.     

Misrecollection prevents older adults from benefitting from semantic relatedness of the memoranda in associative memory

Memory for episodic associations declines in aging, ostensibly due to decreased recollection abilities. Accordingly, associative unitization - the encoding of associated items as one integrated entity - may potentially attenuate age-related associative deficits by enabling familiarity-based retrieval, which is relatively preserved in aging. To test this hypothesis, we induced bottom-up unitization by manipulating semantic relatedness between memoranda. Twenty-four young and 24 older adults studied pairs of object pictures that were either semantically related or unrelated. Participants subsequently discriminated between intact, recombined and new pairs. We found that semantic relatedness increased the contributions of both familiarity and recollection in young adults, but did not improve older adults' performance. Instead, they showed associative deficits, driven by increased recollection-based false recognition. This may reflect a “misrecollection” phenomenon, in which older adults make more false alarms to recombined pairs with particularly high confidence, due to poorer retrieval monitoring regarding semantically-related associative probes.     

Long-term meditation: the relationship between cognitive processes,thinking styles and mindfulness

The aim of this study is to examine the relationship between meditation and cognitive functions. More in depth the purpose is to demonstrate that long-term meditation practice improves attention skills and cognitive flexibility. Eighteen long-term meditation practitioners were compared to a matched control group, who never practiced meditation. Each subject was tested, using computerized software (Presentation Software 9.90), which measured: attention, visual search abilities, working memory and Stroop’s interference tasks. Furthermore, we examined the relationship between long-term meditation practice, mindfulness skills and thinking styles, namely styles of processing information. The results showed significant differences between the two groups, demonstrating that long-term meditation is linked to improvements of attentional functions, working memory and cognitive flexibility.
