Evaluating the Theory-of-Mind Hypothesis of Autism

ABSTRACT— Two decades ago, the theory-of-mind hypothesis of autism was introduced by Baron-Cohen and his colleagues; this theory provided a unified cognitive explanation for the key social and communication symptoms in that disorder. I evaluate the theory-of-mind hypothesis in light of studies that have addressed several key questions: Do children with autism develop theory-of-mind concepts? How can we explain why some children with autism pass theory-of-mind tasks? Do deficits in theory of mind account for the major impairments that characterize autistic disorder? Current research supports the view that autism involves delays and deficits not only in the development of a theory of mind but also in additional aspects of social-affective information processing that extend beyond the traditional boundaries of theory of mind.     

Alexithymia,memory of emotion,emotional awareness,and perfectionism

The Toronto Alexithymia Scale (TAS-20; R. M. Bagby, J. D. A. Parker, & G. J. Taylor, 1994) is a self-assessment instrument designed to measure deficits in meta-emotional functioning (e.g., difficulties in identifying and describing emotions). Four studies were carried out to examine the association between the TAS-20 and (a) performance measures of meta-emotional functioning (memory of emotion and emotional awareness; Studies 1-2) and (b) measures of perfectionistic standards that may possibly be involved in the self-assessment of abilities-difficulties (Studies 3-4). The TAS-20 failed to correlate in the predicted direction with the performance measures but showed sizable correlations with measures of perfectionism. Moreover, perfectionism was found to predict TAS-20 scores independent of depression, anxiety, and somatic complaints. The results are discussed in terms of the TAS-20 measuring primarily certain aspects of meta-emotional self-efficacy.     

Adults also have difficulty recalling one instance of a repeated event

Some forms of abuse, such as domestic violence, tend to occur repeatedly. Although memory for repeated events has received considerable empirical attention, most of this research has used a child sample. Experiments that have examined adult repeated‐event memory tend to use vastly different methodological paradigms to that used for children. To investigate whether the same pattern of findings emerge with young adults, we adapted the methodological paradigm used in child repeated‐event experiments. In this experiment, 41 undergraduate students experienced one, or multiple similar events. All participants were then interviewed about the same event. Participants who had experienced a single‐event were more likely to report correct details than those who had experienced a repeated event. Repeated‐event participants were more likely to report general details. These results have implications for the methodological paradigm which is used to examine adult memory for a recurring event.     

Meta-Analyses of the Associations Between Disinhibited Social Engagement Behaviors and Child Attachment Insecurity or Disorganization

Children with disinhibited social engagement disorder show reduced reticence with strangers, do not check back with their caregiver after venturing away, and may willingly leave with an unfamiliar adult. The recent DSM-5 has moved away from an attachment framework to understand disinhibited social engagement behavior (DSEB) due to studies indicating its presence in previously institutionalized children even after these children are adopted and show a selective, more secure attachment with their substitute caregiver (e.g. Chisholm et al., 1998). This meta-analysis aims to clarify the size of the associations between DSEB and attachment insecurity or disorganization. It also examines whether studies effect sizes differ according to various moderators (e.g., child age, type of attachment and DSEB measures). The results (k?=?24) showed that the associations between DSEB and attachment insecurity (d?=?0.48) or attachment disorganization (d?=?0.47) were of small magnitude. There were no publication biases. As for moderator analyses on both attachment insecurity and disorganization, the effect sizes in studies using DSEB observational measures (respectively d?=?0.63 and 0.57) were of moderate magnitude and stronger than those in studies not using an observational component (respectively d?=?0.28 and 0.32). Given these small-to-moderate associations, attachment can be considered a relationship process associated with DSEB, and attachment-informed interventions could be potential tools to reduce DSEB in children. Nevertheless, given the sizable unshared portion of variance between DSEB and child attachment, future studies should examine other variables related to caregiving and noncaregiving contexts to further understand DSEB.

     

Sex Roles,Gender, and Fear

Male and female college students classified as masculine, feminine, androgynous, or undifferentiated on the Bern (1974) Sex Role Inventory (N = 199) were given the Wolpe (1969) Fear Inventory. Significant differences in average fear scores were seen between men and women and between the four sex-role categories, with sex role and gender contributing equally to the variability. The argument is raised here that excessive fearfulness or fearlessness might be as much a product of sex-role conditioning as a product of gender.     

Cerebral lateralization of language in deaf and hearing people

In Experiment 1 neither hearing nor prelingually deaf signing adolescents showed marked lateralization for lexical decision but, unlike the hearing, the deaf were not impaired by the introduction of pseudohomophones. In Experiment 2 semantic categorization produced a left hemisphere advantage in the hearing for words but not pictures whereas in the deaf words and signs but not pictures showed a right hemisphere advantage. In Experiment 3 the lexical decision and semantic categorization findings were confirmed and both groups showed a right hemisphere advantage for a face/nonface decision task. The possible effect of initial language acquisition on the development of hemispheric lateralization for language is discussed.     

Depression vs. paranoia: Why are there sex differences in mental illness?

Sex differences in proneness to depression and paranoia are seen as reflecting caricatures of women s and men's stereotypical role in a male-dominated, exploitative society Following its major hypothesis that mental illness arises out of failures in the sociability that is inherent in our species, the paper discusses some of the evidence for sex differences in sociability, and some evidence from studies of sex differences in field dependence which, taken together, suggest a sex difference in proneness to shame and guilt This sex difference in ‘superego” style is a mediating factor in proneness to depression and paranoia
