Measuring mindreading in preschoolers: The perspective battery (PERBAT).

OBJECTIVE: The capacity to take another person's visual perspective is pivotal for solving mindreading tests, such as Theory of Mind (ToM) tasks, but most of them heavily rely on domain-general abilities (e.g., language, executive functions). Here we present a novel battery of visual perspective-taking tests for child neuropsychological assessment, the Perspective Battery (PERBAT), which poses a limited load on domain-general abilities. METHODS: The battery includes four tests: i) Block Building; ii) Hide and Seek; iii) Deceptive Figures; iv) Double-Sided Shelf. We administered the PERBAT to 126 typically developing preschoolers (65 males; 3-6-year-old); the participants also performed classical tests of social cognition, language, and nonverbal abstract reasoning. RESULTS: The scores of all the PERBAT tests were significantly and positively related with age and scores of the classical social cognition tests, but not with scores of the language and nonverbal abstract reasoning tests. CONCLUSIONS: The PERBAT could represent a useful neuropsychological tool providing a comprehensive assessment of visual perspective-taking skills in preschool children. Future investigation is needed to examine the validity of the PERBAT with neurotypical samples across countries, race, ethnicity, and language as well as with clinical populations. Longitudinal studies are also encouraged to examine whether early visual perspective-taking weaknesses are associated with later development of mindreading skills.

Visual and kinesthetic motor imagery in adults with different degrees of self-reported motor coordination difficulties.

Developmental Coordination Disorder (DCD) involves difficulties in performing coordinated movements with fine and/or gross motor skills deficits. Several studies showed that DCD is characterized by motor imagery deficits as well. Here we investigated in neurotypical adults (N = 334) the relationships between the ease of imaging two main motor imagery components, that is the visual and the kinesthetic one, self-reported motor coordination difficulties and handwriting speed. Self-reported motor difficulties were measured by the Adult Developmental Co-ordination Disorders/Dyspraxia Checklist (ADC) and scores were used to distinguish three groups: participants at risk of DCD (with both relevant childhood and current motor coordination difficulties); with motor coordination difficulties (relevant current but not childhood difficulties); without motor coordination difficulties (neither current nor childhood difficulties). The main results showed more kinesthetic and visual imagery difficulties in participants at risk of DCD than in those both with and without motor coordination difficulties. Interestingly, the relationships between the two imagery components and motor difficulties were different in the three groups, depending on: 1) the developmental phase (childhood or adulthood) to which motor coordination difficulties referred, and 2) the point of view (self or other), from which images were judged. Instead, no relationship was found between imagery abilities and handwriting speed. Thus, a nuanced pattern of the ease of imaging motor imagery emerged in adults with different degrees of self-reported motor coordination difficulties. These findings could be relevant for the assessment of people candidate to undergo a motor imagery training.

The Integrated Neuropsychological Therapy: A Psychotherapy Model Tying Neuropsychology and Cognitive Behavioral Therapy.

Transdiagnostic cognitive behavioral therapy (CBT) is based on the identification of dysfunctional processes and intervention principles shared across psychopathology. From a neuropsychological perspective, deficits of executive functions and social cognition have been identified as common mechanisms involved in the genesis and maintenance of different psychopathological disorders. The present article describes a new psychotherapy model, the integrated neuropsychological therapy (INPT), built on the principles of transdiagnostic CBT and neuropsychology. Case formulation is operationalized into three levels of functioning, that is, automatic, reflective, and strategic, considering both neuropsychological processes and clinical contents. Treatment planning involves three phases, that is, preparation, enhancement, and change, each consisting of different treatment modules defined according to the above levels of functioning. These modules are selected based on the patient's profile defined during case formulation. The theoretical foundations of INPT are provided, and a case description is presented, which illustrates the implementation of the treatment model.

Validation and psychometric properties of the Italian version of the Power Behavioural System Scale.

The power behavioural system is a neurobehavioral system that motivates a person to acquire and control resources that are important for survival and reproductive success. When activated, its function is to protect or restore the sense of power, influence, or dominance. Repeated experiences of failure in achieving this goal may result in hyperactivation or deactivation of power-oriented behaviours (analogous to the secondary strategies observed with respect to the attachment behavioural system). Gaining a reliable and valid measure of hyperactivation and deactivation of the power system can be important for understanding an individual's responses to different social contexts and, in clinical settings, can help the therapist identify the client's difficulties that may undermine the therapeutic process. In the present study, we developed the Italian version of the Power Behavioural System Scale (PBSS), a self-report measure developed by Shaver et al. (2011) to assess individual differences in hyperactivation and deactivation of the power system. Results indicated an adequate fit to the expected two-factor model, and the measure proved to be reliable and had good convergent and structural validity, allowing the quantification of individual differences in power system hyperactivation and deactivation.

The Relationships between Self-Reported Motor Functioning and Autistic Traits: The Italian Version of the Adult Developmental Coordination Disorders/Dyspraxia Checklist (ADC).

BACKGROUND: We developed the Italian version of the adult developmental co-ordination disorders/dyspraxia checklist (ADC), providing reliability and concurrent validity data for the scale (Aim 1). In addition, we investigated the relationships between motor coordination difficulties and different autistic traits (Aim 2). METHODS: 498 participants (341 females; age range = 18-34) underwent the Italian version of the ADC, as well as a handwriting speed test, the autism spectrum quotient, the empathy quotient, and the systemizing quotient. RESULTS: The distinction between three main factors (A, B, and C) identified in the original version of the ADC was confirmed here. Internal consistency of the ADC subscales was adequate, as well as the correlation with the handwriting speed test used to assess concurrent validity. No substantial sex differences on the ADC scores were found. Furthermore, data revealed that poor autistic-related communication skills and lower levels of systemizing tendencies were, among all the investigated autistic traits, those more strongly associated with higher motor coordination difficulties. CONCLUSIONS: The Italian ADC seems a valuable tool for assessing motor coordination difficulties in adults and can reveal the nuanced impact exerted by different autistic traits on self-reported motor functioning.

Specific Global-Local Visual Processing Abilities Mediate the Influence of Non-social Autistic-like Traits on Mental Rotation.

Inconsistent data are available on mental rotation performance in neurotypicals with high autistic-like traits. Here, we tested whether global-local visual processing abilities mediate the influence of specific autistic-like trait domains (social skill, attention switching, attention-to-detail, communication, and imagination) on mental rotation. Neurotypical participants (N = 128) underwent an assessment of autistic-like traits, a flanker task with hierarchical stimuli, and a mental rotation task. Path analysis showed that Reaction Times on the incongruent/local condition of the flanker task mediated the relationship between attention-to-detail and mental rotation accuracy. These findings indicate that a better capacity of ignoring incongruent global information to identify local information (reduced global interference) in persons with high non-social autistic-like traits, as attention-to-detail, facilitates mental rotation performance.

The effect of autistic traits on disembedding and mental rotation in neurotypical women and men.

Recent data has revealed dissociations between social and non-social skills in both autistic and neurotypical populations. In the present study, we investigated whether specific visuospatial abilities, such as figure disembedding and mental rotation, are differently related to social and non-social autistic traits, in neurotypical women and men. University students (N = 426) completed the Autism Spectrum Quotient (AQ), figure disembedding and mental rotation of two-dimensional figures tasks. AQ social skills (AQ-social) and attention-to-details (AQ-attention) subscales were used as measures of social and non-social autistic traits, respectively. Mental rotation was affected by a significant interaction between sex, social and non-social traits. When non-social traits were above the mean (+ 1 SD), no sex differences in mental rotation were found. Instead, below this value, sex differences depended on the social traits, with men on average outperforming women at middle-to-high social traits, and with a comparable performance, and with women on average outperforming men, at lower social traits. A small positive correlation between figure disembedding and social traits was observed in the overall sample. These results are interpreted in terms of the hyper-systemizing theory of autism and contribute to the evidence of individual differences in the cognitive style of autistic people and neurotypical people with autistic traits.

Empathy through the Pandemic: Changes of Different Emphatic Dimensions during the COVID-19 Outbreak.

Growing evidence suggests that empathy is a relevant psychological trait to face the challenges imposed by the COVID-19 pandemic, but at the present very little is known on whether this multi-dimensional construct has been affected by the pandemic outbreak differently in its separate components. Here, we aimed at filling this gap by capitalizing on the opportunity of having collected data from different self-report measures and cognitive tasks assessing the main dimensions of empathy immediately before the beginning of the global pandemic and about one year later. The results showed a detrimental impact of the pandemic outbreak on empathic social skills but not on both cognitive (perspective-taking) and emotional empathy that instead significantly improved. Thus, reduced empathic social skills could be a weakness to be targeted in psychological interventions to help people cope with the mental health challenges related to COVID-19 pandemic, whereas the ability of understanding another's mental states and emotions could represent a strength in dealing with the current long-lasting crisis.

Anxiety Sensitivity Domains are Differently Affected by Social and Non-social Autistic Traits.

Anxiety sensitivity (AS) is implicated in the development and maintenance of several psychopathological conditions. Non-clinical individuals with high autistic traits may develop anxiety disorders and depressive symptoms. Here, we investigated the relationships of autistic traits with AS dimensions and depression, considering sex. We referred to the two-factor model of the autism spectrum quotient to distinguish social and non-social autistic traits and assessed 345 university students on AS and depression scales. Results showed that only social autistic traits predicted general AS and anxiety-related concerns regarding social and cognitive domains. The present results emphasize the need of assessing multiple domains of anxiety in individuals on the autistic spectrum, differentiating social and non-social traits.

Figure Disembedding: The Gottschaldt's Hidden Figure Test in Children with Typical Development and Autism.

In two studies, we used the Gottschaldt's Hidden Figure Test (GHFT) for assessing figure disembedding ability in children aged 7-11. Study 1 demonstrated in a large sample of typically developing children that GHFT accuracy and time scores differed across age groups, without sex and socioeconomic differences. Thus, we provided normative data only taking into account children's age. In Study 2, GHFT normative values were used to assess children with autism, who were also compared with a closely age-matched group of typical controls. Children with autism achieved time scores at or above the 50th centile and significantly differed from the controls for time score. The GHFT seems a valuable tool for defining the cognitive profile of children with autism.

"Mind the thumb": Judging hand laterality is anchored on the thumb position.

People can decide whether the image of a hand represents a left or a right one. The laterality judgment mainly implies mentally imaging own hand movement (motor simulation) if the stimulus represents a palm, or analysing visual cues, as hand asymmetry, if the stimulus reproduces a dorsum. Here, by capitalizing on evidence underscoring the key role of thumb-palm complex in motor dexterity of human hand, we hypothesise that activation of motor or visual processes when judging hand laterality is due to the different relevance of palm-thumb and dorsum-thumb combinations to hand action. To test this thumb-anchored strategy, in a laterality judgment experiment, we concurrently manipulated the thumb position (flexed or extended) with respect to palm and dorsum, and the human likeness of the hand shape (influencing the salience of the thumb with respect to the hand shape). The main results demonstrated that viewing the flexed thumb from palm or dorsum elicited motor simulation, while viewing the extended thumb activated motor simulation when combined with palm but not dorsum. The present data highlight the pivotal role of the thumb in hand laterality judgments, consistent with its key role in human in-hand manipulation.

"Building blocks and drawing figures is not the same": Neuropsychological bases of block design and Rey figure drawing in typically developing children.

Several studies investigated the neuropsychological bases of spatial construction in developmental samples. However, no study directly tested whether the pattern of the neuropsychological processes implied in spatial construction changed depending on whether a block building or a figure drawing task is considered. Here, we used the path analysis to test the direct and indirect effects of verbal abilities (naming and verbal knowledge), executive functions, figure disembedding and mental rotation on two classical spatial construction tasks: the Rey-Osterrieth Complex Figure (ROCF) and the Block Design (BD). We recruited a sample of 186 typically developing children (age range: 7-12 years). Results showed that ROCF copying was directly influenced by age and figure disembedding, and it was indirectly affected by executive functions, naming and verbal knowledge, whereas BD was influenced in a direct way by verbal knowledge, figure disembedding and mental rotation and indirectly affected by executive functions and naming skills. Moreover, the results showed a full measurement invariance of the path model between sexes, whereas only partial invariance was found for age. Thus, we tested the model in two age groups (age ranges: 7-9.5 and 9.6-12 years) and found that the relationships between the variables of the model changed across development. Although other variables might be relevant to spatial construction, the present findings demonstrate different neuropsychological bases of drawing figures and building blocks in typically developing children.

Switching between the Forest and the Trees: The Contribution of Global to Local Switching to Spatial Constructional Abilities in Typically Developing Children.

BACKGROUND: Spatial analysis encompasses the ability to perceive the visual world by arranging the local elements ("the trees") into a coherent global configuration ("the forest"). During childhood, this ability gradually switches from a local to a global precedence, which contributes to changes in children's spatial construction abilities, such as drawing or building blocks. At present, it is not clear whether enhanced global or local processing or, alternatively, whether switching between these two levels best accounts for children's spatial constructional abilities. METHODS: We assessed typically developing children 7 to 8 years old on a global/local switching task and on two widely used spatial construction tasks (the Rey-Osterrieth Complex Figure and the Block Design test). RESULTS: The ability to switch from global to local level, rather than a global or a local advantage, best accounted for children's performance on both spatial construction tasks. CONCLUSIONS: The present findings contribute to elucidate the relationship between visual perception and spatial construction in children showing that the ease with which children switch perception from global to local processing is an important factor in their performance on tasks requiring complex drawing and block assembling.

Implicit Motor Imagery and the Lateral Occipitotemporal Cortex: Hints for Tailoring Non-Invasive Brain Stimulation.

BACKGROUND: Recent evidence has converged in showing that the lateral occipitotemporal cortex is over-recruited during implicit motor imagery in elderly and in patients with neurodegenerative disorders, such as Parkinson's disease. These data suggest that when automatically imaging movements, individuals exploit neural resources in the visual areas to compensate for the decline in activating motor representations. Thus, the occipitotemporal cortex could represent a cortical target of non-invasive brain stimulation combined with cognitive training to enhance motor imagery performance. Here, we aimed at shedding light on the role of the left and right lateral occipitotemporal cortex in implicit motor imagery. METHODS: We applied online, high-frequency, repetitive transcranial magnetic stimulation (rTMS) over the left and right lateral occipitotemporal cortex while healthy right-handers judged the laterality of hand images. RESULTS: With respect to the sham condition, left hemisphere stimulation specifically reduced accuracy in judging the laterality of right-hand images. Instead, the hallmark of motor simulation, i.e., the biomechanical effect, was never influenced by rTMS. CONCLUSIONS: The lateral occipitotemporal cortex seems to be involved in mental representation of the dominant hand, at least in right-handers, but not in reactivating sensorimotor information during simulation. These findings provide useful hints for developing combined brain stimulation and behavioural trainings to improve motor imagery.

Tendency to Worry and Fear of Mental Health during Italy's COVID-19 Lockdown.

BACKGROUND: We tested whether the tendency to worry could affect psychological responses to quarantine by capitalizing on the opportunity of having collected data before the COVID-19 outbreak on measures of worry, anxiety, and trait mindfulness in a group of university students. METHODS: Twenty-five participants completed self-report measures assessing worry (Penn State Worry Questionnaire, PSWQ), anxiety (Anxiety Sensitivity Index, ASI-3), and trait mindfulness (Mindful Attention Awareness Scale, MAAS) at T0 (pre-lockdown, 4 November 2019-17 February 2020) and T1 (at the end of lockdown, 26 April-30 April 2020). We compared assessments at the two time points in the whole sample and in high and low worriers (defined at T0 by scores on PSWQ respectively above and below 1.5 SD from mean of the Italian normative sample). OUTCOMES: High worriers showed at T1 a significant increase of anxiety sensitivity and fear of mental health in comparison to low worriers. Moreover, in the whole sample, at T1 trait mindfulness was inversely related to worry and fear of mental health. INTERPRETATION: A valuable approach to support individuals experiencing anxiety related to the COVID-19 outbreak could be represented by mindfulness-based interventions improving the ability to focus attention and awareness on the present moment.

Sex differences in implicit motor imagery: Evidence from the hand laterality task.

Behavioural evidence suggest that males outperform females in mentally transforming objects, whereas whether sex differences exist in mentally transforming body part images (implicit motor imagery) is an open issue. The aim of the present study was to fill this gap testing performance of 360 healthy participants on a classical behavioural measure of implicit motor imagery: the hand laterality task. Participants had to judge handedness of hand images portrayed from back and palm and presented in different spatial orientations. Two main findings emerged. First, males were significantly faster than females in judging hands portrayed from palm, in particular left palms at 0°, 90° and 180° orientation, whereas females were faster than males in judging backs, in particular left and right backs at 0° and the left back at 90°. Second, both males and females showed a significant biomechanical effect (faster responses for hands portrayed in medial vs. lateral positions) while judging palms, albeit the effect was stronger in males, whereas only females showed a significant biomechanical effect when judging backs. Thus, males and females seem to differently exploit motor simulation processes during mental transformation of hand images depending on a specific familiarity with body parts portrayed from different views. This result might be taken into account when tailoring motor imagery tasks in applied contexts, as motor rehabilitation.

Identifying neuropsychological predictors of drawing skills in elementary school children.

Much evidence indicates that drawing is related to different neuropsychological abilities in children. However, a comprehensive cognitive model of drawing in children is still lacking. Here, we conducted a study on the neuropsychological predictors of drawing in a sample of 142 typically developing elementary school children (M age = 8.8 years; SD = 1.1). Based on a path analysis, we examined the contribution of visual perception (matching geometrical figures), complex spatial abilities (e.g., complex figures identification and mental rotation), visual attention, working memory, verbal and visual-motor skills, as well as of gender, age and socio-economic status, to copying the Rey-Osterrieth Complex Figure (ROCF). Results showed that ROCF copying was influenced in a specific and additive way by visual perception, visual-motor coordination, and verbal abilities as well as age, while it was indirectly related to visual attention, working memory, and to complex spatial abilities. These findings provide the grounds for identifying the neuropsychological bases of drawing in elementary school children.

The effects of autistic traits and academic degree on visuospatial abilities.

In the present study, we were interested to investigate how autistic traits (including systemizing and empathy) and academic degree influence individuals' visuospatial abilities. To this end, 352 university students completed the Autism Spectrum Quotient (AQ), the Empathy Quotient, the Systemizing Quotient (SQ) and visuospatial tests measuring figure disembedding and mental rotation of two-dimensional figures. Engineering-design students (architecture and engineering) were the most accurate in disembedding and mentally rotating figures, followed by students of physical sciences (computer science, chemistry, physics, etc.) and fact-based humanities (languages, classics, law); biological (psychology and neuroscience, etc.) and systems-based social scientists (economics and commerce) were the least accurate. Engineering-design students also showed higher SQ scores with respect to the other four academic degree subjects, with students of biological sciences showing lower SQ scores. Importantly, results from a path analysis revealed that SQ (but not AQ) exerted an indirect effect on figure disembedding and mental rotations through the influence of the academic degree. Thus, the present findings reveal shady differences in systemizing degree and visuospatial performance within systemizing-based degree subjects. Implications for education are discussed.

Normative data of the Rey-Osterrieth Complex Figure for Italian-speaking elementary school children.

The Rey-Osterrieth Complex Figure Test (ROCF) is a widely used neuropsychological test for the evaluation of drawing disorders in different clinical populations, and, in particular, in persons with neurodevelopmental disorders. The aim of the present study is to provide normative data for ROCF copying (ROCF-Direct copy) and drawing from memory (ROCF-Immediate recall) in Italian-speaking children. The sample consisted of 348 children (147 males and 199 females), aged 7-11 years, recruited from elementary schools in Southern Italy. Normative data were gathered from 312 participants fulfilling the inclusion criteria, and estimated centiles were obtained according to the LMS method providing normalized growth centile standards. Results showed a significant effect of age on performance in both tasks, with a steady increase of drawing accuracy, whereas participants' gender and mean level of parental education did not exert any significant effect. Thus, normative data were stratified by age, and percentile scores were provided allowing a practical use of the ROCF for the clinical evaluation of drawing abilities in both typical and atypical children.
