Which processes are involved in cognitive procedural learning?

Procedural memory is characterised by a relative resistance to pathology, making its assessment of the utmost importance. However, few studies have looked at the cognitive processes involved in cognitive procedural learning. In an initial experiment, we studied the role of different cognitive functions in massed cognitive procedural learning. Our results confirmed the existence of three separate learning phases and, for the first time, demonstrated the involvement of episodic memory and executive functions in the first learning phase. In a second experiment, we studied the effect of distributed learning conditions on the dynamics of procedural learning. This second study confirmed our results but showed that these conditions slow down the process of cognitive procedural learning. Our overall findings call into question the status of functionally autonomous memory system that is currently allotted to procedural memory, and suggest that the role of nonprocedural cognitive components should be taken into account in patient rehabilitation.     

Maternal attitudes and attachment styles in mothers of obese children

This study evaluated categories of attachment style and the maternal attitude toward educational role in a sample of 30 mothers of obese children and a control group of 80 mothers of children of normal weight. All mothers completed the 1994 Attachment Style Questionnaire and the 1958 Parental Attitude Research Instrument. 30 mothers (M age 37.4 yr., range 31 to 54 years; M yr. of education 11.6, range 5 to 18 years) of obese children (range 30 to 60% above normal weight) and a control group of 80 mothers (M age 37.1 yr., range 29 to 52 years; M yr. of schooling 11.4, range 5 to 18 years) of children with normal weight were contacted at the primary school attended by their children and joined the project voluntarily. Age and number of years of education were not significantly different between the two groups of women. There was a significant prevalence of the Insecure Attachment Style in the group of mothers with obese children (66.6%) as compared to the control group of mothers of children of normal weight (38.5%) and significantly higher scores on 6 subscales of the Parental Attitude Research Instrument of Obese compared to Nonobese children. These data indicate that obese children's mothers tend to make the family their exclusive centre of interest. They also tend to dedicate themselves to their children with possessiveness and hyperprotection. They seem to have an insistent requirement of idealisation of their own role as parent and reward expectations that confirm the efficiency of the care they provide their children. Consequently, these findings suggest that in addition to dietetic treatment, it may be important to include a psychological intervention, which involves the mother and aims to modify the relational dynamics between the mother and her obese child.     

Child Assent and Parental Permission in Pediatric Research

Since children are considered incapable ofgiving informed consent to participate inresearch, regulations require that bothparental permission and the assent of thepotential child subject be obtained. Assent andpermission are uniquely bound together, eachserving a different purpose. Parentalpermission protects the child from assumingunreasonable risks. Assent demonstrates respectfor the child and his developing autonomy. Inorder to give meaningful assent, the child mustunderstand that procedures will be performed,voluntarily choose to undergo the procedures,and communicate this choice. Understanding theelements of informed consent has been theparadigm for assessing capacity to give assent.This method leaves the youngest, leastcognitively mature children vulnerable towaiver of assent and forced researchparticipation. Voluntariness can also becompromised by the influence of authorityfigures who can exert undue influence andcoerce children to participate in research. This paper discusses factors that may influencethe decision to give assent/permission,potential parent-child conflict in theassent/permission process and how it isresolved, and potential parental undueinfluence on research participation. Theseissues are illustrated with quotations drawnfrom a larger qualitative study of parentalpermission and child assent (data notpresented). We suggest a developmentalapproach, viewing assent as a continuum rangingfrom mere affirmation in the youngest childrento the equivalent of the informed consentprocess in the mature adolescent.     

Do not put the blame on me: Asymmetric responses to service outcome with autonomous vehicles versus human agents

The present study aims to examine customer responses to negative (vs. positive) service outcome with an autonomous vehicle (AV) vis-à-vis human agent. In the first study we manipulate the outcome of the service (negative vs. positive) and the type of service agent (AV vs. human) to evaluate customers' satisfaction with the service. Based on the results of the first study, in the second study we focus only on the negative outcome scenario and we examine how the perceived blame of the AV (vs. human agent) affects customers' satisfaction. Finally, in the third study we introduce another mediator, namely perceived competence, which explains why people attribute less blame to the AV (vs. human agent). Customers' satisfaction is higher for the AV only in the case of a negative service outcome, while no differences emerge when the service had a positive outcome. Additionally, AVs (vs. human agent) are perceived as less competent and blameworthy, leading to a higher customer satisfaction with the service in case of a negative outcome. These results show a customer under-reaction to negative service outcome with AVs. This has relevance for the design and policy implications related to AVs. Our results also provide insights into the psychological underpinnings of acceptance of AVs replacing human agents. This study extends previous literature by showing circumstances in which customers are more (or less) satisfied with an AVs (vs. human agents) and the psychological drivers of these asymmetrical responses.     

Gender differences in the perception of women in magazine advertising

Male and female college students (N=137) rated 10 control and 10 target magazine advertisements for appeal and for the perceived sexism displayed in the ads. Males did not differ in their ratings of target and control ad appeal. Females rated target ads as less appealing than control ads, and gave target ads lower appeal ratings than did males. Females also rated target ads as more sexist than did males, although both sexes rated target ads as more sexist than control ads. All subjects also completed the Attitudes Toward Women Scale, on which females displayed more liberal attitudes than males.     

Effect of luminance on perceptual alternation of ambiguous patterns

The perceptual alternation of the Necker cube, in its stationary phase, is studied as a function of the stimulus luminance down to the extreme condition in which the cones are completely inactivated so that the pattern of neural excitation reaching the primary visual cortex is very different from the normal one. No evident effect of luminance was found under passive observation either on the reversal rate or on the features of data distributions. Moreover, the complementary situation in which perception is based only on the cones does not affect the phenomenon either. These results permit the assumption that the perceptual alternation in its stationary phase, is a passive and automatic process, that is affected neither by a satiation of the first levels of the visual system nor by the psychological attitude of the subject consequent on dazzling the retina.     

Body perception in athletes and non-athletes

20 male athletes and 20 control subjects were required to make estimates of the length of their body dimensions and of external comparison objects. Athletes were more accurate in judging body dimensions than comparison objects while the reverse pattern was demonstrated by non-athletes. The results are discussed on the basis of the possible influence of sports activities on body perception.

Systemic-Oriented Psychological Counselling for Caregivers of People with Severe Brain Injury: Reflections on a Clinical Case

Severe brain injuries can have dramatic consequences on family life, often changing rules and routines and fostering intense and prolonged caregiving duties. People affected by the injuries have to face relevant restrictions in their activities and a loss of independence. Thus, primary caregivers are often involved in their assistance, which can entail the help for self-care, movements and many activities of daily living. Furthermore, cognitive and behavioural symptoms can complicate communication, disrupt previous relationships and put an additional strain on all family members. Indeed, caregiving relationships take place in wider familial and societal contexts and are obviously influenced by previous characteristic of such relationships, as they were before the onset of the pathological condition. Therefore, a thorough examination of typical emotions, feelings and thoughts that can emerge during caregiving must be paralleled by an ecological and developmental perspective, in order to appraise the complexity of these cases and provide effective interventions. The present work aims to address such topics taking inspiration from a clinical case.     

Relationship quality of persons with obstructive sleep apnoea syndrome

In the field of sleep disorders, the quality of couple relationship is arousing increasing attention, given its implications for quality of life and treatment adherence. The aim of the present study was to evaluate relationship quality in a sample of treated or untreated patients with Obstructive Sleep Apnoea Syndrome. Eighty-seven patients were recruited in a hospital-based Centre for Sleep Medicine. Subjects were administered the Dyadic Adjustment Scale (DAS) to evaluate relationship quality, and the Epworth Sleepiness Scale (ESS). Apnoea-hypopnoea indexes (AHI) were collected through nocturnal polysomnography or home testing with a portable monitoring device. Although the DAS average scores were similar to local normative values, relationship quality was significantly lower in the untreated patients when compared with the ones treated. The ESS scores showed a negative correlation with many DAS scores, whereas no significant correlation emerged for AHI. Such data suggest a significant impact of perceived sleep apnoea symptoms on marital satisfaction, even though in the absence of striking differences between the whole sample and the general population.
