The use of visualisation techniques in teaching has enabled students to improve their memory and comprehension of written narratives. Psychological research reveals how various factors can influence visualisation and learning, including; adopting a character’s perspective; constructing self-related images; multi-sensory text representing episodic events; and imagery ability. These factors were explored using narratives that represented real events, which contained subjective and objective information. University students (age range 18–25 years) recalled the narratives in a first person, third person and neutral perspective. In the first person perspective, information was connected to their sense of ‘self’, which improved memory. Additionally, the first person perspective improved memory for subjective and objective information for high imagery ability individuals and subjective information for low imagery ability individuals. Overall, the findings suggest that visualisation, first person perspective and narratives representing real experiences improve memory and comprehension. Implications for practice are also discussed.

Two perspectives from which memories can be retrieved have been distinguished: field resembles the view from the first-person vantage point of original experience, whereas observer resembles the view from the third-person vantage point of a spectator. There is evidence that the incidences of the two types of perspective differ between at least two different cultural groups. It is hypothesised here that this is a special case of a more general relation between memory perspective and cultural individualism, such that field and observer perspectives are more prevalent among people from, respectively, relatively individualist and relatively collectivist societies. Memory perspectives adopted by participants from a range of different countries were recorded, and were found to vary in the predicted manner. Regression analysis showed that the potential effects of three other cultural variables - uncertainty avoidance, masculinity and, to a lesser extent, power distance - were eclipsed by the influence of individualism, and the implications are discussed.

People caring for family members who have dementia often experience considerable levels of anxiety and depression. However, relatively little is known about the awareness of carer distress among people with dementia. This study investigated whether or not people with dementia are aware of the level of distress experienced by their carers. Two groups of participants were studied, a dementia group and a control group of people with arthritis. Each group consisted of pairs of people, the person with dementia or arthritis and the family member who acted as their main carer; 40 pairs participated in total. For both groups, the carer's psychological health was rated by the carer themselves and by the care-recipient, using the Hospital Anxiety and Depression Scale. For the dementia group, memory functioning in the person with dementia was rated by the care-recipient themselves and by the carer, using the Memory Function Scale. The ratings made by the carer and care-recipient were compared to give an indication of the level of awareness in the care-recipient. People with dementia have a significant level of awareness of their carers' state of psychological health. Their awareness follows the same pattern as that shown by a control group of people with arthritis. The level of awareness of carer psychological health shown by the dementia group was not related to their level of awareness of their own memory difficulties. The clinical implications of awareness of carer distress in people with dementia should be considered.

In response to the comment by Vuoksimaa and Kaprio (2010) on our previous article on sex differences in left-handedness (Papadatou-Pastou, Martin, Munafò, and Jones, 2008), we carried out an additional meta-analysis to explore whether the widely observed tendency for rates of left-handedness to be greater among male than female individuals is also found in Scandinavian (Nordic) studies. The overall male-to-female ratio for left- to right-handedness odds provides evidence in favor of this hypothesis. However, the results were subject to a significant moderating effect related to nation of origin. We discuss the potential impact on observed measures of additive rather than multiplicative processes that may underlie sex differences in handedness and also the date-of-study effect on handedness rates.

Many people with dementia are enabled to live at home by the support of a close family member, who takes on the role of a carer. Considerable research has investigated the impact of caring for a person who has dementia. In early research, there was a tendency to overlook the experiences of the person with dementia and, in particular, the relationship between the two persons. This has now been corrected by a growing body of research on the relationships between people with dementia and the family members who care for them. Peer-reviewed publications on the influence of relationship factors in dementia caregiving were reviewed. The impact of dementia on the quality of relationships is examined, together with the impact of relationship quality on the experience of living with dementia. The different forms that relationships can take in the context of dementia are considered, and an integrative theoretical framework is proposed. A neglect of direct evidence from the person with dementia is identified, and possible ways of combating this are considered. Clinical implications are drawn with regard to supporting the carer, the person with dementia, and their relationship.

The possibility is investigated that cerebral dominance for language and handedness share a common X-linkage and that the relation between the two is therefore a function of sex. In particular, an X-linked recessive account is shown to predict an overall configuration of language dominance, handedness and sex within which there is a sex effect in the pattern of language dominance among right-handed but not left-handed people. The recent accurate determination of cerebral dominance among relatively large samples of the general population by means of functional transcranial Doppler ultrasonography makes it possible to test this new theory rigorously, and its parameter-free pattern of predictions is found to be supported.

Evidence from studies of intentional learning suggests that the accuracy of recall is not assisted by appropriate enactment at retrieval, as opposed to encoding. In the present study, long-term recall of spatial arrays following incidental learning (text messaging or calculator use) was tested under three different motor conditions at retrieval. For both letter and number arrays, the accuracy of recall was found to be improved by relevant enactment at the time of retrieval, relative to retrieval with no movement. In contrast, irrelevant movement was found to produce an impairment in accuracy. The overall accuracy of recalling a letter array was found to be a power-law function of the frequency of exposure to the array. The findings are discussed in terms of the hypothesis that appropriate movement during memory retrieval recruits egocentric representations that supplement allocentric representations subserving longer term spatial recall.

Why do people choose to surround themselves with possessions? An explanation has been offered by D. A. Norman (2004) in terms of the stimulation of 3 levels of psychological processing that map onto an object's appearance, its usability, and its ability to evoke reflective processing, including emotion. Two experiments were carried out to investigate participants' choices among valued objects, and found that affective factors (including links to current and past, euphoric and dysphoric emotion) played a dominant role in predictive modeling. The role was, however, significantly modulated by alexithymia. The extent to which object choice could be predicted was lower for those with higher levels of alexithymia than for those with lower levels. Nevertheless, a prominent linkage to current dysphoria was observed to emerge for higher levels of alexithymia, whose implications are considered.

Two experiments examined affective priming of global and local perception. Participants attempted to detect a target that might be present as either a global or a local shape. Verbal primes were used in 1 experiment, and pictorial primes were used in the other. In both experiments, positive primes led to improved performance on the nonpreferred dimension. For participants exhibiting global precedence, detection of local targets was significantly improved, whereas for participants exhibiting local precedence, detection of global targets was significantly improved. The results provide support for an interpretation of the effects of positive affective priming in terms of increased perceptual flexibility.

Two memory perspectives have been distinguished: a field perspective where events are re-experienced in the first person, and an observer perspective where events are witnessed in the third person. Two experiments examined the influence of memory perspective on objective memory performance. In both experiments participants were presented with a series of verbal passages, each of which contained several different categories of information. For four of these categories (pertaining to affective reactions, physical sensations, psychological states, and associated ideas), recall was significantly higher when a field perspective was adopted than when an observer perspective was adopted, but for the five other categories (pertaining to physical actions, personal appearance, fine details, spatial relations, and peripheral details) there was no significant effect of perspective upon recall. The study is examined in the context of mental models and imagined episodic events.
