Cette thèse examine l'évolution du concept d'esprit dans la lignée humaine, en comparaison du développement de ce concept chez l’enfant, afin de déterminer quand les êtres humains auraient commencé à penser aux autres et à eux-mêmes en tant qu’esprit dans un corps. Une revue de la littérature sur le concept au travers l’histoire a permis de le définir comme un outil cognitif désignant les agents intentionnels ayant une influence sur la matière. Compte tenu de cette définition, le concept d'esprit est donc un précurseur du sens de l’agentivité et de la faculté cognitive permettant d'attribuer l'esprit à autrui, également appelée Théorie de l'Esprit (TdE). Il est suggéré que l’agentivité et la TdE se développent en trois stades dans la lignée, de la même manière qu’on l’observe chez l’enfant : 1) la conscience de soi et des autres, 2) l’attention conjointe et 3) la présence d'émotions sociales complexes telles que la compassion. Une revue systématique a ensuite été réalisée dans le but de sélectionner, sans biais, des données archéologiques infirmant ou confirmant cette hypothèse. La revue est basée sur l’impact annuel moyen des textes (nombre de citations) et utilise des combinaisons de mots-clés en lien avec les manifestations probable du concept de l’esprit, de l’agentivité et de la TdE durant la préhistoire. Les résultats de l'analyse portent à croire que : 1) l’agentivité et la TdE1 (conscience de soi et des autres) existeraient au moins depuis Homo habilis, mais probablement depuis l’ancêtre commun à Pan et Homo; 2) la TdE2 (attention conjointe) serait présente au moins depuis Homo erectus/ergaster, mais probablement depuis l’ancêtre commun à Pan et Homo si nous supposons que les trois stades ont évolué de manière consécutive tel qu’observé chez l’enfant; et 3) la TdE3 serait présente au moins depuis Homo erectus/ergaster mais probablement depuis l’ancêtre commun de Pan et Homo. Finalement, on peut aussi conclure que : 4) le volume du néocortex semble avoir augmenté en parallèle à la maîtrise et au développement de l’agentivité et de la TdE, et ce depuis au moins le début de la lignée Homo. Le rôle de l’esprit dans la complexité sociale et les raisons de son émergence sont explorés en détails dans la conclusion. / This thesis examines the evolution of the concept of mind in the human lineage, in comparison with the development of this concept in children, to determine when humans would have started to think of others and of themselves as a spirit in a body. A review of the literature on the concept throughout history has made it possible to define it as a cognitive tool enabling intentional agents to have an influence on matter. Given this definition, the concept of mind is therefore a precursor to the sense of agency and the cognitive ability to attribute mind to others, also known as Theory of Mind (ToM). It is proposed that agency and ToM evolve in three stages along the Homo line, like what is seen in children: 1) awareness of self and others, 2) joint attention, and 3) the presence of complex social emotions such as compassion. A systematic review was then carried out with the aim of selecting, without bias, archaeological data invalidating or confirming this hypothesis. The review was based on the average annual impact of the articles (number of citations) and used combinations of keywords related to the likely manifestations of the concept of mind, agency, and ToM during prehistory. The results of the analysis suggest that: 1) Agency and ToM1 (awareness of self and others) existed at least since Homo habilis, but probably since the common ancestor to Pan and Homo; 2) ToM2 (joint attention) was present at least in Homo erectus/ergaster, but probably since the common ancestor between Pan and Homo, if we assume that the three stages evolved consecutively as observed in children; and 3) the ToM3 (compex social emotions) was present at least since Homo erectus/ergaster but probably already in the common ancestor of Pan and Homo. Finally, we can also suggest that: 4) the volume of the neocortex seems to have increased in parallel with the mastery and development of agency and ToE, and this being the case since at least the beginning of the Homo lineage. The role of the mind in social complexity and the reasons for its evolution are explored further in the conclusion.

This dissertation explores Wittgenstein’s views on the mind-body problem. It is possible to provide an examination of Wittgenstein’s approach by tracing the evolution of the theory of mind and the mind-body problem, by considering the current ways of dealing with the mind-body problem, and Wittgenstein’s critique of the notion of the mind. Wittgenstein’s views on the nature of philosophy and the relationship between philosophy and psychology make it possible to understand and as this dissertation argues – see beyond – the conceptual confusion that has since arisen out of philosophic tradition that perpetuates a ‘myth of the mind’. Schools of thought such as the Cartesians and cognitivists have attempted, through the construction of various elaborate theories, to solve the ‘riddle’ of the mind and to address the so-called ‘mind-body problem’. Cognitive science, in particular, has used the tradition and the myth of the mind as a basis for its research. Wittgenstein shows that such thinking is particularly muddled. By examining Wittgenstein’s approach to the mind-body problem, it is argued here that theories based on the tradition of the ‘myth of the mind’ are inherently flawed. Wittgenstein uses his methods, consisting of his notions of ‘grammar’, ‘language games’ and the re-arrangement of concepts, to extrapolate meaning and to see through the conceptual confusions that the use of language causes and that give rise to the mind-body problem . / Psychology / M.A. (Psychology)

Conventional breast-cancer prevention strategies tend to focus on the reduction of physical breast-cancer risk factors while neglecting psychosocial factors potentially associated with its development. Yet, there is a wealth of evidence linking psychosocial factors such as the occurrence of and maladaptive coping with bereavement and other stressful life events, certain personality traits, and a lack of social support, to breast-cancer incidence, survival and mortality.This thesis aimed to design, implement and evaluate an electronic Coping-Enhancement Programme for the Bereaved (CEPB), addressing such psychosocial factors. Furthermore, participants’ experiences of the programme were to be explored. An experimental 2x2 independent measures design with triangulation was used, employing qualitative and quantitative methodology. Participants’ experiences were elicited qualitatively through blogs and message boards. The two independent variables were (1) emotional-expression-and-stress-reduction (EESR), and (2) psycho-education. Dependent variables were: (1) maladaptive coping with bereavement, (2) maladaptive coping with stressful life events, (3) social support, and (4) awareness of the connections between psychological and physical health. An additional dependent variable was conformity. A Web site containing message boards and blogs was created. Thirty-one women completed a psychological screening form and were then randomly assigned to one of four conditions (EESR-only, psycho-education-only, EESR-plus-pyscho-education, or the control group who received no intervention). They participated in online exercises designed to aid emotional expression and stress reduction (‘Art and Laughter for Wellbeing’) and/or received psycho-education through the reading of autobiographical accounts of breast-cancer sufferers. Participants were analysed on the dependent variables three times: before the programme to obtain a baseline measurement, after the programme, and at six-week follow-up. Thematic analysis was used to illustrate the process of the CEPB, as well as to confirm or disconfirm quantitative results. Analyses of covariance revealed that after the programme, taking part in ‘Art and Laughter for Wellbeing’ was associated with lower maladaptive coping with bereavement, while reading autobiographical accounts of breast-cancer sufferers was associated with lower maladaptive coping with stressful life events. Participation in both conditions was associated with higher levels of social support, and taking part in either condition was associated with lower levels of conformity. The latter effect persisted at follow-up. Mixed analyses of variance showed changes over time in three dependent variables. The CEPB was generally viewed as useful, helpful and enjoyable by participants. Implications for future research are discussed, and a biopsychosocial model of breast-cancer prevention is proposed.

Processing information related to the self and inferring the mental state of another person is known to involve the ventromedial prefrontal cortex (VMPFC) in both younger and older adults (Stone et al., 2008; Kelley et al., 2002; Hynes et al., 2006; Ruby et al., 2009). According to the dorsolateral prefrontal (DLPF) theory of cognitive ageing, processing of the self should not be affected by healthy adult ageing as functions related to the VMPFC remain relatively preserved compared to functions related to the DLPF cortex (MacPherson et al., 2002). Similarly, no age difference should emerge in those tasks thought to tap functions of the VMPFC. The aim of this PhD is to investigate the effect of healthy adult ageing on the ability to process information related to the self and others. A series of experiments was designed to compare the performance of younger and older adults on tasks that investigate processing and retrieval of self-related information (e.g. behaviour prediction, personality judgement, mental state inferences, self-referential). The tasks differ in the extent to which they rely on cognitive effort. The results show that ageing does not affect self-related judgements. A further series of experiments designed to investigate affective and cognitive Theory of Mind (ToM) show that the affective performance, thought to rely on VMPFC activity, is not affected by age. In contrast, the performance of older participants differs from that of younger adults on cognitive ToM task, thought to involve DLPFC brain areas. A final experiment investigated the ability to make self versus other related judgments in a confabulating patient. The results show that the ability to reflect on the self but not on others was intact. In summary, the findings demonstrate that processing self-information and making ToM inferences remains intact in older individuals and is not overtly impaired by confabulation.

A test of standing broad jump ability was administered to ninety-three sixth grade boys to compare the kinesthetic and demonstration methods of instruction. The subjects were classified on the Neilson-Cozens Classification Index and divided into three groups. The first group received the kinesthetic method of instruction, the second group was instructed using the demonstration method, and the third group did not receive any formal instruction. The data were examined by computing the mean and standard deviation of each pre-test and post-test group. The mean and standard deviation of the pre-test scores were 60.61 and 7.589. The mean and standard deviation of the post-test scores were 61.31 and 7.397. When each pre-test score was subtracted from its corresponding post-test score it was revealed that the demonstration group showed an increase in performance of eighteen boys, the kinesthetic group increased by sixteen boys and the group receiving no formal instruction increased by seven boys. Analysis of variance of matched groups revealed an F ratio of 2.68 which was not significant at the .05 level. An alternate approach was attempted in which the effect of the pre-test scores were partialled out from the post-test scores. Subjected to matched group analysis of variance design indicated an F ratio of 2.68 which was not significant at the .05 level. The resu1ts of a randomized group analysis without matching revealed an F ratio of 2.68 which was quite similar to the previous results and also insignificant at the .05 level. Randomized group analysis without matching between post-test scores and the regression equation indicated an F ratio of 2.72 which again was found insignificant at the .05 level of significance. It was found that no statistically significant difference could be obtained by use of one instructional technique exclusively in preference to another.

A particularly intriguing aspect of personal identity is the staying power of the first arguments. Many of the earliest arguments have remained influential to contemporary theories, even if they sometimes go unacknowledged. One of the most prominent of those long-lived theories comes from Descartes. In this paper I establish the intellectual background, framework, and implications of Cartesian dualism. With this theory in mind I examine Derek Parfit’s We Are Not Human Beings. Despite his denial dualism’s relevance, Parfit’s argument for personal identity contains Cartesian Dualism within it. His examples, definitions, and “intuitions” are compatible, if not more supportive of the Cartesian philosophy. To have the strongest argument that we are not human beings Parfit needs dualism - even if he will not directly acknowledge it.

Motivating students is a central challenge for many teachers, particularly in subjects students commonly perceive as “impenetrable,” such as statistics. One line of motivation research by C.S. Dweck (2006) has found that when students believe their intelligence is malleable (i.e., a growth mindset) and that learning is a function of effort, they show greater motivation, accept more learning challenges, and have improved performance outcomes relative to students who believe their intelligence is fixed (e.g., “I’m not a math person”). This dissertation extends research regarding implicit theories of intelligence by examining how metaphors of the growth mindset (e.g., the mind is a muscle) can be integrated as feedback into a computer program to encourage students to implicitly adopt the growth mindset relevant to statistics. The present study manipulated framing conditions with metaphorical, literal, and no feedback about the growth mindset. Results show that framing feedback implicitly in terms of the “mind as muscle” metaphor increased non-math major undergraduates’ willingness to accept learning challenges and their overall score on testing items relevant to statistical literacy, as compared to students who received literal feedback or no feedback about the growth mindset. Also, overall, gender differences were noted, with males accepting more learning challenges, passing on fewer difficult items, and having higher scores on testing items than females. Findings also indicate that participants’ psychological reactance and interest in fitness and muscularity (metaphor resonance) did not meaningfully change participants’ learning outcomes. / text

Comorbid chronic insomnia was found highly prevalent in breast cancer patients. It also persisted through survivorship. Negative emotions upon diagnosis and during the course of cancer treatment might complicate the underlying mediating factors between stress and insomnia found in non-cancer population. Cognitive Behavioural Therapy (CBT) has been evidenced in improving insomnia. With the appreciation of Mindfulness training in improving cognitive flexibility and rumination, a novel treatment approach integrating CBT and mindfulness—Mind-Body Intervention (MBI) was developed. 　　　There were three objectives in the research. Firstly, prevalence data on insomnia and clinical profile of Hong Kong Chinese breast cancer survivors were obtained. Secondly, the mediating roles of negative emotions, hyperarousal, pre-sleep arousals in the relationship between perceived stress and insomnia were examined. Thirdly, the effects of CBT and MBI for breast cancer survivors with insomnia were investigated. 　　　In the first study, 1049 women who survived from non-metastatic breast cancer were invited to complete a survey on stress, mental health, arousals and insomnia. Those who met psychophysiological insomnia were invited to participate in the second study, which was a multisite randomized controlled trial. The 73 participants were allocated to CBT (n=24), MBI (n=27) or waiting list control, WLC (n=22). Both treatments were five weekly-session group therapies. Outcomes on insomnia, mental health, arousals, dysfunctional beliefs, quality of life and mindfulness, were obtained on baseline, post-treatment, 3-month and 6-month follow-ups. 　　　Results of the first study revealed 34.6% of the participants suffered from clinical insomnia, while 15.1%, 27.4% and 12.8% endorsed moderate to extremely severe depression, anxiety and stress respectively. Duration of insomnia was correlated with insomnia severity. Hyperarousal was found moderating cognitive ore-sleep arousal and anxiety, these in turn, together with depression mediated the relationship between perceived stress and insomnia severity. Results of the second study supported the hypothesis both CBT and MBI improved insomnia and other psychological symptoms, while WLC did not. After treatment, significant decreases of 59 and 67 minutes of total wake time per night were found for CBT and MBI respectively. Sleep efficiency values significantly increased in CBT (12.2%) and MBI (12.7%). Moderate to large effect sizes and clinically significant differences were found in most sleep and psychological variables. Generally, CBT produced larger effect sizes than MBI on post-treatment. The therapeutic gains were found sustaining through 3-month to 6-month follow-ups in both treatments. However, the effect sizes of CBT were on the declining trend, while those of MBI were more stable. 　　　The results suggested that insomnia and anxiety were frequently experienced in breast cancer even after completing the medical treatments. The longer the survivors suffered from insomnia, the higher the severity was found. In additional to the cognitive pre-sleep arousal, the important mediating roles of depression and anxiety imply that insomnia treatments should incorporate strategies designed to help in decreasing rumination/worry before bedtime and improving mental health conditions. The findings also provided initial evidence for the efficacy of MBI as a viable treatment for insomnia. More vigorous randomized controlled trial and the long-term efficacy could be further studied. / published_or_final_version / Clinical Psychology / Doctoral / Doctor of Psychology

The unique linguistic experience of bilingualism purportedly produces cognitive control advantages. Although there is a significant body of evidence supporting this view, there are also several recently published research studies that failed to replicate bilingual advantages. Furthermore, there is some evidence of a publication bias that favors findings supporting a bilingual advantage. The purpose of this study was to address this discrepancy in the literature by examining performance of bilinguals and monolinguals on a variety of cognitive control tasks. A second purpose was to determine how bilinguals are able to achieve better performance if they do indeed have an advantage. Specifically, we were interested in whether there were differences in the tendency for bilinguals and monolinguals to mind wander, a phenomenon associated with poorer cognitive control performance. We hypothesized that bilinguals would demonstrate better performance than monolinguals on Operation Span, Numerical Stroop, SART, Color- Shape, and Letter Memory tasks, which are measures of working memory, proactive inhibition, reactive inhibition, shifting, and updating, respectively. We further hypothesized that if bilinguals outperformed monolinguals on these tasks, this would be associated with less mind wandering for bilinguals. Participants completed all measures of cognitive control and were probed periodically throughout the tasks for mind wandering. Accuracy and reaction times where appropriate were recorded for each task, and data from 52 monolinguals and 52 bilinguals were analyzed. The results did not reveal any bilingual advantages. For all tasks, performance of the two groups was equivalent with the exception that monolinguals had faster reaction times for Numerical Stroop, SART, and Color-Shape tasks. There were also no differences between language groups in mind wandering tendencies. Secondary analyses examining age of acquisition (i.e., early versus late) and similarity of languages (i.e., same-script versus differentscript) did not change the overall pattern of no bilingual advantages. The lack of a bilingual advantage supports recent calls to temper bilingual advantage claims and shows a need for future research to address which underlying factors of bilingualism may or may not have an effect on cognitive control.

Background: Multiple Sclerosis (MS) is a chronic, degenerative, neurological condition affecting approximately 85,000 people in the UK. The impact of MS on physical abilities is well‐known and there is increasing recognition of the impact of MS on mood and cognitive function. Recently MS has been linked to impaired emotion recognition and impaired Theory of Mind (ToM –the ability to attribute mental states, e.g. beliefs to oneself and others). Methods: This study measured executive function, ToM, empathy and quality of life in an MS sample (n=42). A correlational analysis was then conducted to determine whether executive function was associated with the other variables. Results: Two executive function measures (Mental Flexibility and Response to Feedback) were significantly associated with two ToM tasks (Revised Eyes and Stories). Mental Flexibility and the Revised Eyes ToM task were significantly associated with measures of empathy, but this effect was not present in the other executive function or ToM tasks. Neither executive functioning nor ToM measures were significantly associated with reported quality of life. Conclusion: Overall, the MS sample demonstrated specific ToM impairment, no significant empathy impairment and widespread executive impairment relative to normative data. Low rates of depression (10%) and higher levels of anxiety (29%) were found. MS participants rated the psychological impact of MS as equivalent to the physical impact, highlighting the importance of addressing psychological aspects of MS.
