Do subitizing deficits in developmental dyscalculia involve pattern recognition weakness?

The abilities of children diagnosed with developmental dyscalculia (DD) were examined in two types of object enumeration: subitizing, and small estimation (5–9 dots). Subitizing is usually defined as a fast and accurate assessment of a number of small dots (range 1 to 4 dots), and estimation is an imprecise process to assess a large number of items (range 5 dots or more). Based on reaction time (RT) and accuracy analysis, our results indicated a deficit in the subitizing and small estimation range among DD participants in relation to controls. There are indications that subitizing is based on pattern recognition, thus presenting dots in a canonical shape in the estimation range should result in a subitizing‐like pattern. In line with this theory, our control group presented a subitizing‐like pattern in the small estimation range for canonically arranged dots, whereas the DD participants presented a deficit in the estimation of canonically arranged dots. The present finding indicates that pattern recognition difficulties may play a significant role in both subitizing and subitizing deficits among those with DD.     

Plasticity during childhood and adolescence: innovative approaches to investigating neurocognitive development

Adolescence is a period of profound change, which holds substantial developmental milestones, but also unique challenges to the individual. In this opinion paper, we highlight the potential of combining two recently developed behavioural and neural training techniques (cognitive bias modification and functional magnetic neuroimaging‐based neurofeedback) into a research approach that could help make the most of increased levels of plasticity during childhood and adolescence. We discuss how this powerful combination could be used to explore changing brain–behaviour relationships throughout development in the context of emotion processing, a cognitive domain that exhibits continuous development throughout the second decade of life. By targeting both behaviour and brain response, we would also be in an excellent position to define sensible time windows for enhancing plasticity, thereby allowing for targeted intervention approaches that can help improve emotion processing in both typically and atypically developing populations.     

Ambivalence over emotional expression and symptom attribution are associated with self‐reported somatic symptoms in Singaporean school adolescents

Although somatization is common across cultures, its meanings may differ as culture shapes emotional experience. Thus, instead of treating somatization as a form of psychopathology, it is more useful to conceptualize it as an idiom of distress, and how complaints of somatic symptoms are related to social relationships, patterns of emotional expression and symptom attribution in a cultural context. This study seeks to explore whether ambivalence over emotional expression and causal attribution would shed light on the meanings of somatization among Asian adolescents. Three hundred secondary school adolescents in Singapore participated in this study. The main results show that emotional ambivalence, biomedical and Traditional Chinese Medicinal causal beliefs, and magical attribution contributed to additional variance in somatic symptoms over and above the variance explained by emotional distress. These findings are discussed from both psychological and cultural perspectives.     

The importance of social and ideal social dimensions in self‐congruity research

Chronic or situational self‐construal moderates the effects of four self‐congruity (SC) dimensions (i.e., actual, ideal, social, and ideal social) on brand evaluations. Past research has mainly focused on the actual and ideal SC effects; these effects have been found to be stronger than the social and ideal social SC effects. However, the findings of past research are based on samples from individualistic cultures. Individualists have a dominant independent self‐construal. We conduct two experiments to show that the social and ideal social SC effects are stronger than the actual and ideal SC effects for individuals with a dominant interdependent self‐construal. In Study 1, using samples from collectivistic cultures, four SC effects are compared. In Study 2, we examine how primed self‐construal, whether independent or interdependent, impacts the four SC effects. This research documents the importance of the social and ideal social dimensions in SC research.     

Coping Response Inventory: Assessing coping among Iranian college students and introductory development of an adapted Iranian Coping Response Inventory (CRI)

Coping is related to mental and physical health outcomes, but cultural and societal differences may influence its nature and structure. This study reports on the adaptation of the Coping Responses Inventory for Adult (CRI-A) to the Iranian social and cultural context. Study 1 was designed to obtain qualitative data and test the construct and discriminative validity of coping scales. Factor analysis of the CRI and Iranian items yielded seven factors: Religious Coping, Problem Solving, Cognitive Avoidance, Positive Reappraisal, Seeking Guidance and Support, Seeking Alternative Rewards, and Acceptance/Resignation. Internally, consistencies varied considerably from 0.92 to 0.53. All sub-scales from the Coping Responses Inventory for Adult (CRI-A) were resistant to social desirability biases with the exception of Religious Coping and Problem Solving. In Study 2, the replicability of the adapted CRI-A factorial structure and concurrent validity for the newly developed religious coping sub-scale was demonstrated. Given the importance of the role of religious coping in health and well-being outcomes, the expression and use of which may be substantially influenced by cultural practices and norms, it is recommended that future research pursues the validation of context-specific constructs of religious and spiritual coping.     

The Portuguese version of Addenbrooke’s Cognitive Examination–Revised (ACE-R) in the diagnosis of subcortical vascular dementia and Alzheimer’s disease

The aim of this study was to investigate the accuracy of the Portuguese version of Addenbrooke’s Cognitive Examination–Revised (ACE-R) in detecting and differentiating early stage subcortical vascular dementia (SVD) from early stage Alzheimer’s disease (AD). Ninety-two subjects (18 SVD patients, 36 AD patients, and 38 healthy controls) were assessed using the ACE-R. Between-group’s differences were evaluated using the Quade’s rank analysis of covariance. The diagnostic accuracy and discriminatory ability of the ACE-R were examined via receiver operating characteristic (ROC) analysis. The ACE-R was able to successfully discriminate between patients and healthy subjects. The mean ACE-R total scores differed between SVD and AD patients; there were also significant differences in attention and orientation and in memory measures between the groups. An optimal cut-off of 72/73 was found for the detection of AD (sensitivity: 97%; specificity: 92%) and SVD (sensitivity: 100%; specificity: 92%).     

Different Effects of Dual Task Demands on the Speech of Young and Older Adults

Abstract

Young and older adults provided language samples in response to elicitation questions while concurrently performing 3 different tasks. The language samples were scored on three dimensions: fluency, grammatical complexity, and content. Previous research has shown that older adults use a restricted speech register that is grammatically less complex than young adults’ and has suggested that this restricted speech register is buffered from the costs of dual task demands. This hypothesis was tested by comparing language samples collected during a baseline condition with those produced while the participants were performing the concurrent tasks. The results indicate that young and older adults adopt different strategies when confronted with dual task demands. Young adults shift to a restricted speech register when confronted with dual task demands. Older adults, who were already using a restricted speech register, became less fluent although the grammatical complexity and informational content of their speech was preserved. Hence, some but not all aspects of older adults’ speech are buffered from dual task demands.
