Polygamous Interest in a Mononormative Nation: The Roles of Sex and Sociosexuality in Polygamous Interest in a Heterosexual Sample from the UK.

Polygamy is a form of "one-sided" consensually non-monogamous relationship where one person has multiple committed partners, each of whom is only involved with that one person. It was likely a reoccurring feature of ancestral mating that posed adaptive problems for our ancestors. Yet polygamy, and multi-partnering more generally, is understudied in Western cultures, raising questions about the existence of polygamous interest and whether this is calibrated adaptively to personal conditions.

The effects of temperature priming on cooperation in the iterated prisoner's dilemma.

Based on initial research findings by Williams and Bargh (2008) and Kang, Williams, Clark, Gray and Bargh (2011) on the interaction between interpersonal and physical warmth, theoretical models such as cognitive scaffolding and the importance of evaluations of interpersonal warmth in trust-based decisions, this experiment investigated the effect of temperature priming on 30 pairs of British university students with hot and cold objects on frequency of cooperation in a game of iterated Prisoner's Dilemma. Participants were found to cooperate significantly more frequently when primed with hot objects than with cold objects, supporting the assertion that physical warmth sensation positively affects interpersonal trust evaluation. No support was found for the prediction that male-male pairs would cooperate less than female-female pairs.

Abnormal patterns of cerebral lateralisation as revealed by the Universal Chimeric Faces Task in individuals with autistic disorder.

A previous study by Workman, Chilvers, Yeomans, and Taylor (2006), using the "Universal" Chimeric Faces Task (UCFT) for six emotional expressions, demonstrated that an overall left hemispatial/right hemisphere (RH) advantage has begun to develop by the age of 7-8. Moreover, the development of this left hemispatial advantage was observed to correlate positively with the ability to read emotions in the faces of others. Adopting the UCFT, the current study compared autistic children (11-15) with unimpaired children of two age groups (5-6 and 7-8) from this previous study.

Emotion lateralisation: developments throughout the lifespan.

There is a great amount of research on hemispheric lateralisation for processing emotions and on the recognition of emotions across the lifespan. However, few researchers have explored the links between these two measures. This paper highlights how trends in these two research areas inform our understanding of how lateralisation for emotion processing may influence emotion recognition performance throughout the lifespan, including if the development of emotion lateralisation is a response to our environmental experiences of learning (experience dependent) or a result of having specific experiences at a particular time (experience expectant).

Visual laterality effects in readers of a deep and a shallow orthography.

Using a tachistoscopic split-field paradigm, hemifield asymmetry for single word recognition was examined in monolingual English speakers and in fluent bilingual English-Welsh speakers. A robust right hemifield advantage was found for both groups and both languages. Among bilinguals, the laterality index was significantly greater for Welsh than for English, supporting previous findings.

Development of cerebral lateralisation for recognition of emotions in chimeric faces in children aged 5 to 11.

In contrast to research into the development of language laterality, there has been relatively little research into the development of lateralisation of emotional processing. If language lateralisation begins in childhood and is complete by puberty (Lenneberg, 1967) it seems reasonable that the lateralisation of the perception of emotions might also occur during this period. In this study a split field chimeric faces test using the six universal facial expressions proposed by Ekman and Friesen (1971), an emotion in the eyes test, and a situational cartoon test were administered to three groups of children aged 5/6, 7/8, and 10/11.

Differential bilingual laterality: mythical monster found in Wales.

Paradis (1992) likens studies of bilingual laterality to reported sightings of the Loch Ness Monster, in that although some studies claim differential laterality much conflicting research evidence does not-and like the mythical Scottish monster, what reason have we to suspect that any such phenomenon might exist? This study reexamines differential bilingual laterality using four groups of English-Welsh bilinguals which differ in their age of acquisition and in their environment of acquisition. Using a split visual field paradigm we present evidence which, supports the notion of greater right hemisphere processing in a later learned language. Our findings also suggest the pattern of lateralization in bilinguals is strongly affected by the specific language environment during development such that the shift toward greater right hemisphere involvement for the later learned language will be more pronounced in individuals which are brought up in areas where that language is not regularly heard.
