Theory of mind in nonhuman primates

Since the BBS article in which Premack and Woodruff (1978) asked "Does the chimpanzee have a theory of mind?," it has been repeatedly claimed that there is observational and experimental evidence that apes have mental state concepts, such as "want" and "know." Unlike research on the development of theory of mind in childhood, however, no substantial progress has been made through this work with nonhuman primates. A survey of empirical studies of imitation, self-recognition, social relationships, deception, role-taking, and perspective-taking suggests that in every case where nonhuman primate behavior has been interpreted as a sign of theory of mind, it could instead have occurred by chance or as a product of nonmentalistic processes such as associative learning or inferences based on nonmental categories. Arguments to the effect that, in spite of this, the theory of mind hypothesis should be accepted because it is more parsimonious than alternatives or because it is supported by convergent evidence are not compelling. Such arguments are based on unsupportable assumptions about the role of parsimony in science and either ignore the requirement that convergent evidence proceed from independent assumptions, or fail to show that it supports the theory of mind hypothesis over nonmentalist alternatives. Progress in research on theory of mind requires experimental procedures that can distinguish the theory of mind hypothesis from nonmentalist alternatives. A procedure that may have this potential is proposed. It uses conditional discrimination training and transfer tests to determine whether chimpanzees have the concept "see." Commentators are invited to identify flaws in the procedure and to suggest alternatives.     

Prevention of anxiety symptoms in children: results from a universal school-based trial

The present study evaluated the effectiveness of a universal school-based cognitive behavior prevention program (the FRIENDS program) for childhood anxiety. Participants were 638 children, ages 9 to 12 years, from 14 schools in North Rhine-Westphalia, Germany. All the children completed standardized measures of anxiety and depression, social and adaptive functioning, coping strategies, social skills, and perfectionism before and after the 10-week FRIENDS program and at two follow-up assessments (6 and 12 months) or wait period. Children who participated in the FRIENDS program exhibited significantly fewer anxiety and depressive symptoms, and lower perfectionism scores than children in the control group at 12-month follow-up. Younger children (9-10-year-olds) displayed treatment gains immediately after the intervention, whereas older children (11-12-year-olds) showed anxiety reduction only at 6- and 12-month follow-up. Perfectionism and avoidant coping acted as mediators of pre- to postintervention changes in anxiety scores. This study provides empirical evidence for the utility of the FRIENDS program in reducing anxiety and depressive symptoms among German children.     

Disorganized Attachment and Inhibitory Capacity: Predicting Externalizing Problem Behaviors

The aim of the present study was to investigate whether attachment insecurity, focusing on disorganized attachment, and the executive function (EF) component of inhibition, assessed at age 5, were longitudinally related to general externalizing problem behaviors as well as to specific symptoms of ADHD and Autism spectrum disorder (ASD), and callous-unemotional (CU) traits. General externalizing problem behaviors were also measured at age 5 to allow for a developmental analysis. Outcome variables were rated by parents and teachers. The sample consisted of 65 children with an oversampling of children with high levels of externalizing behaviors. Attachment was evaluated using a story stem attachment doll play procedure. Inhibition was measured using four different tasks. The results showed that both disorganized attachment and poor inhibition were longitudinally related to all outcome variables. Controlling for initial level of externalizing problem behavior, poor inhibition predicted ADHD symptoms and externalizing problem behaviors, independent of disorganized attachment, whereas for ASD symptoms no predictive relations remained. Disorganized attachment independently predicted CU traits.     

Influences of Affect Associated with Routine Out-of-Home Activities on Subjective Well-Being

A survey of a random sample of 1,330 Swedish residents assessed the relationships between affect associated with performance of routine out-of-home activities, mood, and judgments of life satisfaction (cognitive subjective wellbeing, CSWB). Regression analyses showed that sociodemographic variables accounted for most variance in CSWB (7%) and least in mood (2%). In agreement with previous research, CSWB increased with income, employment, and cohabiting with a spouse, and had a U-formed relationship with age. Affect associated with routine activities accounted for more variance than the socio-demographic variables in mood (30%) and in CSWB (13%). Mood partially mediated the effect on CSWB of affect associated with the activities. The results suggest that future policy-related research should consider the possibility that community-provided resources that facilitate performance of routine out-of-home activities would increase life satisfaction.     

Mourning the dead,mourning the disappeared: The enigma of the absent–presence

Freud's interest in the impact of death on the living goes back further than Mourning and Melancholia (1917e, [1915]). In Totem and Taboo (1912–13) Freud noted the ambivalence of the emotions we experience in relation to the dead. In this paper, I focus on Mourning and Melancholia as a landmark in the understanding of both the normal and psychopathological aspects of mourning and depressive processes in human beings. Mourning and Melancholia bridges Freud's first and second topographic theories of the psychic apparatus and constitutes for many authors the foundation of his theory of internal object relations. With this psychoanalytic understanding of mourning as a framework, I discuss ‘special mourning processes,’ such as the those confronted by psychoanalysts in Argentina when treating the relatives of thousands of people who were ‘disappeared’ by the military dictatorship in the 1970s; they are ‘special’ in the sense that the external reality [which] constitutes the starting point of the psychic mourning process, as described by Freud, is absent. I argue that the ‘absent–presence’ of the body as an enigmatic message initiates a special mourning process that bears certain characteristics of, and is isomorphic to, Laplanche's seduction theory.     

Computer‐assisted reading intervention with a phonics approach for children using cochlear implants or hearing aids

The present study examined computer‐assisted reading intervention with a phonics approach for deaf and hard of hearing (DHH) children in Sweden using cochlear implants or hearing aids, or a combination of both. The study included 48 children, 5, 6 and 7 years of age. Sixteen children with normal hearing (NH) served as a reference group. The first purpose of the study was to compare NH and DHH children's reading ability at pre and post‐intervention. The second purpose was to investigate effects of the intervention. Cognitive and demographic factors were analyzed in relation to reading improvement. Results showed no statistically significant difference for reading ability at the group level, although NH children showed overall higher reading scores at both test points. Age comparisons revealed a statistically significant higher reading ability in the NH 7‐year‐olds compared to the DHH 7‐year‐olds. The intervention proved successful for word decoding accuracy, passage comprehension and as a reduction of nonword decoding errors in both NH and DHH children. Reading improvement was associated with complex working memory and phonological processing skills in NH children. Correspondent associations were observed with visual working memory and letter knowledge in the DHH children. Age was the only demographic factor that was significantly correlated with reading improvement. The results suggest that DHH children's beginning reading may be influenced by visual strategies that might explain the reading delay in the older children.     

Dynamic interplay of depression,perfectionism and self-regulation on procrastination

This study aimed at investigating the intercorrelation among affective, cognitive and behavioural components on procrastination. A total of 402 undergraduate students (115 males, 286 females, 1 not indicated) participated in the study. Students completed the General Procrastination Scale, Depression, Anxiety and Stress Scale, Frost Multidimensional Perfectionism Scale and Self-regulation Inventory. A constructed hypothesised model was tested by utilising path analysis. Overall, the analysis indicated that the model sufficiently explained the data. The findings showed the multicorrelation among the variables, ranging from 14 to 58. Squared multiple correlation coefficients (R²) of procrastination revealed that endogenous and mediator variables explained 33% of the total variance in procrastination. The results demonstrated the importance of affect, cognition and behaviour on problematic delay referred to as procrastination.     

Neuropsychology of Environmental Navigation in Humans: Review and Meta-Analysis of fMRI Studies in Healthy Participants

In the past 20 years, many studies in the cognitive neurosciences have analyzed human ability to navigate in recently learned and familiar environments by investigating the cognitive processes involved in successful navigation. In this study, we reviewed the main experimental paradigms and made a cognitive-oriented meta-analysis of fMRI studies of human navigation to underline the importance of the experimental designs and cognitive tasks used to assess navigational skills. We performed a general activation likelihood estimation (ALE) meta-analysis of 66 fMRI experiments to identify the neural substrates underpinning general aspects of human navigation. Four individual ALE analyses were performed to identify the neural substrates of different experimental paradigms (i.e., familiar vs. recently learned environments) and different navigational strategies (allocentric vs. egocentric). Results of the general ALE analysis highlighted a wide network of areas with clusters in the occipital, parietal, frontal and temporal lobes, especially in the parahippocampal cortex. Familiar environments seem to be processed by an extended temporal-frontal network, whereas recently learned environments require activation in the parahippocampal cortex and the parietal and occipital lobes. Allocentric strategy is subtended by the same areas as egocentric strategy, but the latter elicits greater activation in the right precuneus, middle occipital lobe and angular gyrus. Our results suggest that different neural correlates are involved in recalling a well-learned or recently acquired environment and that different networks of areas subtend egocentric and allocentric strategies.
