Relations between mental verb and false belief understanding in Cantonese-speaking children

Previous research has shown that linguistic forms that codify mental contents bear a specific relation with children’s false belief understanding. These forms include mental verbs and their following complements, yet the two have not been considered separately. The current study examined the roles of mental verb semantics and the complement syntax in children’s false belief understanding. Independent tasks were used to measure verb meaning, complements, and false belief understanding such that the verbs in question were present only in the verb meaning test, and no linguistic devices biased toward false belief were used in the false belief test. We focused on (a) some mental verbs that obligatorily affirm or negate what follows and (b) sentential complements, the content of which is to be evaluated against the mind of another person, not reality. Results showed that only (a) predicted false belief understanding in a group of Cantonese-speaking 4-year-olds, controlling for nonverbal intelligence and general language ability. In particular, children’s understanding of the strong nonfactive semantics of the Cantonese verbs /ji5-wai4/ (“falsely think”) predicted false belief understanding most strongly. The current findings suggest that false belief understanding is specifically related to the comprehension of mental verbs that entail false thought in their semantics.     

Perspective-taking and depth of theory-of-mind reasoning in sequential-move games

Theory-of-mind (ToM) involves modeling an individual's mental states to plan one's action and to anticipate others' actions through recursive reasoning that may be myopic (with limited recursion) or predictive (with full recursion). ToM recursion was examined using a series of two-player, sequential-move matrix games with a maximum of three steps. Participants were assigned the role of Player I, controlling the initial and the last step, or of Player II, controlling the second step. Appropriate for the assigned role, participants either anticipated or planned Player II's strategy at the second step, and then determined Player I's optimal strategy at the first step. Participants more readily used predictive reasoning as Player II (i.e., planning one's own move) than as Player I (i.e., anticipating an opponent's move), although they did not differ when translating reasoning outcome about the second step to optimal action in the first step. Perspective-taking influenced likelihood of predictive reasoning, but it did not affect the rate at which participants acquired it during the experimental block. We conclude that the depth of ToM recursion (related to perspective-taking mechanisms) and rational application of belief-desire to action (instrumental rationality) constitute separate cognitive processes in ToM reasoning.     

Gender differences in subjective well-being, self-esteem and psychosocial functioning in adolescents with symptoms of anxiety and depression: findings from the Nord-Trøndelag Health Study

Derdikman‐Eiron, R., Indredavik, M. S., Bratberg, G. H., Taraldsen, G., Bakken, I. J. & Colton, M. (2011). Gender differences in subjective well‐being, self‐esteem and psychosocial functioning in adolescents with symptoms of anxiety and depression: Findings from the Nord‐Trøndelag health study. Scandinavian Journal of Psychology52, 261–267. Gender differences in the prevalence of symptoms of anxiety and depression during adolescence are well documented. However, little attention has been given to differences in subjective well‐being, self‐esteem and psychosocial functioning between boys and girls with symptoms of anxiety and depression. The aim of this study was to investigate gender differences in the associations between such symptoms and subjective well‐being, self‐esteem, school functioning and social relations in adolescents. Data were taken from a major population‐based Norwegian study, the Nord‐Trøndelag Health study (HUNT), in which 8984 (91% of all invited) adolescents, aged 13–19 years, completed an extensive self‐report questionnaire. Although prevalence rates of symptoms of anxiety and depression were higher in girls than in boys, a significant interaction between gender and symptoms of anxiety and depression was found in respect of each of the following outcome variables: subjective well‐being, self‐esteem, academic problems, frequency of meeting friends and the feeling of not having enough friends. These interactions indicate that the associations between symptoms of anxiety and depression and lower subjective well‐being and self‐esteem, more academic problems in school and lower social functioning were stronger for boys than for girls. Our findings may contribute to an earlier assessment and more efficient treatment of male adolescent anxiety and depression.     

Representation and working memory in early arithmetic

Working memory has been implicated in the early acquisition of arithmetic skill, but the relations among different components of working memory, performance on different types of arithmetic problems, and development have not been explored. Preschool and Grade 1 children completed measures of phonological, visual-spatial, and central executive working memory, as well as nonverbal and verbal arithmetic problems, some of which included irrelevant information. For preschool children, accuracy was higher on nonverbal problems than on verbal problems, and the best and only unique predictor of performance on the standard nonverbal problems was visual-spatial working memory. This finding is consistent with the view that most preschoolers use a mental model for arithmetic that requires visual-spatial working memory. For Grade 1 children, performance was equivalent on nonverbal and verbal problems, and phonological working memory was the best predictor of performance on standard verbal problems. For both age groups, problems with added irrelevant information were substantially more difficult than standard problems, and in some cases measures of the central executive predicted performance. Assessing performance on different components of working memory in conjunction with different types of arithmetic problems provided new insights into the developing relations between working memory and how children do arithmetic.     

Executive functions in children with Autism Spectrum Disorders

Executive dysfunction is a characteristic impairment of individuals with Autism Spectrum Disorders (ASD). However whether such deficits are related to autism per se, or to associated intellectual disability is unclear. This paper examines executive functions in a group of children with ASD (N = 54, all IQ?70) in relation to a typically developing control group individually matched on the basis of age, gender, IQ and vocabulary. Significant impairments in the inhibition of prepotent responses (Stroop, Junior Hayling Test) and planning (Tower of London) were reported for children with ASD, with preserved performance for mental flexibility (Wisconsin Card Sorting Task) and generativity (Verbal Fluency). Atypical age-related patterns of performance were reported on tasks tapping response inhibition and self-monitoring for children with ASD compared to controls. The disparity between these and previous research findings are discussed. A multidimensional notion of executive functions is proposed, with difficulties in planning, the inhibition of prepotent responses and self-monitoring reflecting characteristic features of ASD that are independent of IQ and verbal ability, and relatively stable across the childhood years.     

Are investors really willing to agree to disagree? An experimental investigation of how disagreement and attention to disagreement affect trading behavior

Using a series of laboratory markets, this paper provides evidence that a willingness to engage in speculative trade is largely driven by a failure of traders to account for information about value implicit in other traders’ actions and that this behavior arises because traders construct myopic mental models that ignore the perspective of other traders. In a baseline set of markets, where traders are prompted to estimate fundamental value but are not overtly prompted to consider disagreement, I find that traders are generally insensitive to adverse selection and readily engage in suboptimal, speculative trade. Moreover, this effect does not decline across trials suggesting that market feedback alone is unlikely to correct traders’ behavior. In contrast, when traders are prompted to assess disagreement over asset values or when they trade in more transparent markets, they appear less willing to “agree to disagree.” These results provide insight into why investors depart from rational trading strategies and how investor psychology will influence trading behavior.

Équivalence de la version en français pour le Canada et de la version originale états-unienne de l’Adult Self-Report

The aim of the present study was to evaluate the equivalence of the French-Canadian version of the Adult Self-Report (ASR; Achenbach & Rescorla, 2003) to its original English (USA) version. Both the original English version and the newly translated French-Canadian version were administered to 251 bilingual students from four Canadian provinces (Manitoba, New-Brunswick, Ontario, and Quebec), with a one to two weeks interval. Correlations varying from 0.72 to 0.87 indicated a high degree of correspondence between the scales of the two versions. Cohen's d calculated using Morris and DeShon's (2002) formula for within-subjects designs indicate that differences between mean scores varied from near-zero (d = 0.01) to small (d = 0.19), and suggest that they are not clinically significant. Ordinal alpha coefficients for the scales of the French-Canadian version varied from 0.66 to 0.96 but are inferior to those of the English version in seven of the eleven scales. Globally, results indicate that the equivalence of the French-Canadian version to the original English version of the ASR is sufficient to recommend its use.     

Positive mental health moderates the association between depression and suicide ideation: A longitudinal study

Background/Objective: Depression and suicide ideation regularly occur together. Yet, little is known about factors that buffer individuals against the development of suicide ideation. The present study investigated, whether positive mental health buffers the association between depression and suicide ideation in a longitudinal study design. Methods: A total of 207 German students (70.3% female; age: M = 26.04, SD = 5.33) were assessed at a baseline evaluation and again twelve months later. Data were collected using self-report questionnaires. Linear hierarchical regression analysis was used to analyze the data. Positive mental health was considered to moderate the impact of depression on suicide ideation – controlling for age and gender. Results: Positive mental health was shown to moderate the impact of depression on suicide ideation: in those students who reported higher levels of positive mental health, depression severity showed no association with suicide ideation over time. Conclusion: Positive mental health seems to confer resilience and should be taken into account, when assessing individuals for suicide risk.     

Early identification of mental health problems in schools: The status of instrumentation

When embedded within a continuum of mental health services including both prevention and treatment, school-based mental health identification programs can promote improved academic and mental health functioning among students. This article describes the scientific status of assessment instrumentation that may be used for early mental health identification in schools. Currently available instruments are described in terms of their ability to accurately detect youth with mental health problems. Implications for selecting mental health screening and assessment instruments and integrating them into schools are discussed. Finally, a range of approaches to early identification in schools as well as some of the broader ethical and practical issues related to the integration of these strategies into a school-wide continuum of services are presented.
