Promoting theory of mind during middle childhood: A training program

Evidence that conversations about the mind foster improvements in theory of mind (ToM) is growing, but their efficacy in typically developing school-aged children has yet to be demonstrated. To address this gap, we designed a conversation-based training program for 9- and 10-year-olds and measured its effectiveness by pre- and post-test comparisons of performance on age-appropriate ToM tasks for two groups (matched at pre-test for gender, age, socioeconomic background, verbal ability, reading comprehension, executive functions, and ToM) who were assigned to either the intervention condition (n=45) or an active control condition (n=46). The intervention group showed significantly greater gains in ToM than the control group; this contrast was stable over 2 months, and (in a subsample) the improvement in ToM was independent of any changes in executive functions. Implications for the role of conversations about the mind in childrens mental state reasoning are discussed.

Promoting theory of mind in older adults: does age play a role?

Objectives: Previous research on age-related changes in Theory of Mind (ToM) showed a decline in older adults, particularly pronounced over 75 years of age. Evidence that ToM may be enhanced in healthy aging people has been demonstrated, but no study has focused on the role of age on the effects of ToM training for elderly people. The present study was designed to examine the efficacy of a ToM training on practiced (ToM Strange Stories) and transfer tasks (ToM Animations) in both young and older adults. Method: The study involved 127 older adults belonging to two age groups: young–old (Mage = 64.41; SD = 2.49; range: 60–69 years) and old–old (Mage = 75.66; SD = 4.38; range: 70–85 years), randomly assigned to either a ToM group or a control group condition. All participants took part in two 2-hour testing sessions and four 2-hour training sessions. Results: Results showed that both young–old and old–old adults in the ToM group condition improved their ability to reason on complex-mental states significantly more than participants in the control group condition. This positive effect of the training was evident on practiced and transfer ToM tasks. Crucially, age did not moderate the effect of the ToM training. Conclusion: These findings demonstrate that young–old and old–old adults equally benefit from the ToM training. Implications for the positive effect of the ToM training in old–old adults are discussed.

Training for generalization in theory of mind: A study with older adults

Theory of Mind (ToM) refers to the ability to attribute independent mental states to self and others in order to explain and predict social behavior. Recent research in this area has shown a decline in ToM abilities associated with normal aging that is of a moderate magnitude or greater. Very few studies have investigated whether it is possible to improve older adults’ ToM abilities. The present study was designed to address this gap in the literature by evaluating the impact of a ToM training on practiced and transfer tasks. We provided older adults with a variety of activities designed to facilitate the generalization of benefits to other ToM-demanding tasks. Participants were 63 healthy older adults, native Italian speakers (Mage = 71.44, SD = 5.24, age range: 63–81 years). Participants were randomly assigned to one of two groups: the ToM training (age range: 63–81 years) and the physical-conversation training (age range: 64–81 years). Training effects were measured using the strange stories (practiced task) and the animation task (transfer task). Results revealed the efficacy of the training in producing improvements on practiced but also on transfer tasks.

Theory of mind plasticity in aging: The role of baseline, verbal knowledge, and executive functions

ABSTRACT Theory of Mind (ToM) refers to the ability to attribute mental states to the self and others in order to explain and predict social behaviour. Meta-analytic results have shown a decline in ToM abilities in healthy older adults. Recent research has also highlighted the possibility of enhancing older adults’ ToM performance through group conversations focused on mental states. Our aim was to determine whether the extent to which older people benefited from a ToM training was predicted by performance on a battery of executive functioning tasks, on baselines in ToM tasks, on verbal knowledge. Forty-three older adults (60–84 years) participated in a three-session ToM training programme that has previously shown to be effective in improving ToM ability. Results showed that verbal knowledge predicted training gains in practiced ToM tasks. In addition, age, executive functions and baseline performance predicted training gains in non-practiced ToM tasks. Results are discussed in light of the amplification model.

Theory of Mind and social relationships in older adults: the role of social motivation

Objectives: Previous research has shown that individual differences in Theory of Mind (ToM) are crucial for peoples social relationships. However, very few studies have investigated this issue in ageing. The present study was designed to fill this gap and examine the associations between ToM and social relationships in elderly adults. In doing so, this study considered peoples relationships with their relatives and friends, and examined the possible moderating role of social motivation. Method: The study involved 53 healthy older adults (age: M = 67.91; SD = 6.93; range: 60--85 years). All participants were tested collectively during a 2-hr session and completed a demographic questionnaire as well as a battery of tests assessing verbal ability (vocabulary and word fluency), ToM and social relationships. They also answered a social motivation question. Results: Results showed that individual differences in older peoples ToM were overall significantly associated with those in relationships with friends, but not relatives. In addition, the Hayes moderating procedure showed that individual differences in ToM were related to those in friendships only for those people who had a high or medium level of social motivation. Conclusion: These findings underline the importance of motivation in guiding the use of ToM in everyday social interactions.

Relations between theory of mind and executive function in middle childhood: A short-term longitudinal study

Studies with preschool children have shown significant links between childrens executive function (EF) and theory of mind (ToM), but few studies have examined these associations in primary school children. To address this gap, we designed a three-wave cross-lagged longitudinal study in which we followed a group of 113 children (61 boys) across three time points from age 9.5-10.5years (mean age at Time 1=112.3months, SD=4.18; mean age at Time 2=118.3months, SD=4.15; mean age at Time 3=124.7months, SD=4.06). At each time point, we measured EF (working memory and inhibitory control), ToM, and language. Our analyses showed (a) moderate rank-order stability of individual differences in both EF and ToM and (b) growth in ToM task performance across time. Cross-lagged longitudinal analyses revealed an asymmetric developmental relation between ToM and working memory. Early working memory predicted later ToM but not vice versa. Our results suggest a specific role for working memory in the ongoing development of ToM in middle childhood.

The role of false-belief understanding in preschoolers’ development of metamemory: A training study

ABSTRACT The study herein investigated the mechanisms that may account for the relationship between theory of mind (ToM) and metamemory, adopting a dynamic approach that combined a focus on individual differences with the rigorousness of a training design. Sixty-six 4- to 5-year-old children were recruited and assigned to one of two training conditions: a ToM and a control condition. Intervention and control groups were equivalent at pretest for age, verbal ability, working memory, ToM and metamemory. Results showed that following the intervention children in the ToM group were better than those in the control group in their first-order, second-order false belief understanding, and metamemory. Crucially, improvements in first-order false belief understanding, but not in second-order false belief understanding, mediated the positive effect of the training program on metamemory.

Promoting theory of mind in school-aged children: Direct and transfer effects

Despite theory of mind (ToM) has a role in social and cognitive development in school aged children, very few studies have proposed interventions to promote ToM in middle childhood. To fill this gap, we developed a novel ToM training program for 9- to 10-year-old children. Results showed that, after the intervention, children in the ToM group improved in ToM task performance significantly more than children in the control condition. The positive effect of the ToM intervention generalized to a new film-based ToM task and was not determined by pre-existing individual differences in ToM, cognitive, and executive skills between groups.
