Satisfaction and frustration of autonomy and relatedness needs: Associations with parenting dimensions and psychological functioning

Framed from Basic Psychological Needs Theory (Ryan and Deci in American Psychologist 55:68–78; Ryan, Deci, American Psychologist 55:68–78, 2000) and Ka?itçiba?i’s Autonomous-Related Self Theory (Journal of Cross-Cultural Psychology 36:1–20; Ka?itçiba?i, Journal of Cross-Cultural Psychology 36:1–20, 2005), the study examined the relationships of adolescents’ satisfaction and frustration of autonomy and relatedness, with (a) adolescents’ perception of mother’s and father’s psychological control and autonomy support, and (b) adolescents’ self-acceptance and anxiety. Participants were 556 adolescents (M?=?17.25, SD?=?0.92). Path analysis showed more significant associations of autonomy support with satisfaction/frustration of autonomy and relatedness than psychological control, reporting also some differences between parents. Moreover, both satisfaction and frustration of autonomy and relatedness were associated with adolescents’ self-acceptance and anxiety although in different ways. Our study provides further data, useful to understand how needs for autonomy and relatedness are associated with parenting dimensions and contribute to the adjustment of adolescents living in psychologically interdependent cultures, taking into account the role of each parent as well as the separate contribution of need satisfaction and need frustration.     

Rats build and update topological representations through exploration

Although rats are able to build complex spatial representations of their surroundings during exploration, the nature of the encoded information is still a matter for debate. In particular, it is not well established if rats can process the topological structure of the environment in such a way that they are aware of the connections existing between remote places. Here, rats were first exposed for four 5-min trials to a complex environment divided into several sectors that were separated by doors allowing either unrestricted or restricted access to other sectors. In the fifth test trial, we measured the behavior of the animals while they explored the same environment in which, however, they faced changes that either altered or did not alter the topological structure of the environment. In experiment 1, closing previously opened doors prevented the rat from having direct access between corresponding sectors. In experiment 2, opening previously closed doors allowed direct access between sectors that had not been directly accessible. In each experiment, control doors allowed us to discard the mere influence of door manipulation. We compared the rats’ exploratory behavior in response to door manipulations that either strongly altered or did not alter the ability to commute between sectors and found evidence that the animals displayed differential reactions to the two types of door manipulations. This implies that during exploration rats build a precise map of the connectivity of space that can be flexibly updated and used for efficient navigation.     

Access to environmental stimulation via eyelid responses for persons with acquired brain injury and multiple disabilities: a new microswitch arrangement

This study assessed a new microswitch arrangement for eyelid responses using an optic sensor placed above the cheekbone and a small sticker on the person's eyelid. This new arrangement, which was designed to avoid interference of the microswitch with the person's visual functioning, was tested on three adults with acquired brain injury and multiple (consciousness, communication, and motor) disabilities. The study was carried out according to a non-concurrent multiple baseline design across participants. Data showed the new microswitch arrangement was suitable for all three participants, who increased their responding during the intervention phase of the study when their responses allowed them to access preferred stimulation. Practical implications of the findings are discussed.     

Reading aloud pseudohomophones in Italian: Always an advantage

In the present article, the lexical contribution to nonword reading was evaluated using Italian pseudohomophones that contained atypical letters or letter sequences. Pseudohomophones were read faster than orthographically matched nonwords in both mixed (Experiment 1) and pure (Experiment 2) lists; in addition, a base-word frequency effect was obtained in both conditions. The same pseudohomophone advantage was observed when nonwords without atypical letter sequences were mixed in the experimental list (Experiment 3 ), and it disappeared only in lexical decision, in which pseudohomophones were rejected as quickly as control nonwords. The pattern of results was explained by assuming that, due to their orthographic properties, the Italian pseudohomophones did not benefit from an orthographic lexical contribution and were mainly processed through the interaction system between the sublexical mechanisms and the phonological output lexicon.     

What Causes Internalising Traits and Autistic Traits to Co-occur in Adolescence? A Community-Based Twin Study

Autism shows a high degree of comorbidity with anxiety disorders. Adolescence is a time of increased stress and vulnerability to internalising problems. This study addresses for the first time the degree of genetic and environmental overlap between autistic traits (total measure and subscales) and internalising traits in a community-based adolescent twin sample. Parents of 12-14-year-old twins (N?=?3,232 pairs; 3,460 males, 3,004 females) reported on the twins’ internalising and autistic traits. Autistic trait subscales were created using principal component analysis. Bivariate twin model-fitting was conducted. Autistic and internalising traits correlated moderately (r?=?0.30). Genetic influences on individual traits were substantial but genetic overlap between traits was moderate (genetic correlation: males?=?0.30, females?=?0.12). Shared environmental influences were low for internalising traits and moderate for autistic traits, and showed considerable overlap (shared environmental correlation: males?=?0.53, females?=?1). Nonshared environmental influences were moderate for internalising traits and low for autistic traits and showed low overlap. A multiple component solution was found for autistic traits and of the derived subscales, autistic-like ‘Social Unease’ showed the most phenotypic and genetic overlap with internalising traits.
