New frontiers for psychology and education: Robotics
2004
The paper reviews the first attempts to study the educational and psychological usefulness of robotics: (1) the social and cooperative dimensions involved in the robot-building activities; (2) the reasoning strategies implied in building and programming robots; (3) the influences of robotics on mathematical and scientific achievement; (4) the use of robotics in modification of social skills of autistic children.
Aging and prospective memory: the role of working memory and monitoring processes
2008
Background and aims: Remembering to execute an earlier planned action is essential in everyday life, and is a prerequisite for independent living in old age. The purpose of the present study was to determine the influence of age in performing a prospective memory (PM) task and to analyze the differential contribution of working memory and attentional monitoring demands. Methods: In Experiment 1, a group of young and two groups of old adults were assigned to one of two low-demanding conditions: a picture-naming task (only-Naming) and a picture-naming plus a PM task (Naming+PM). In Experiment 2, a group of young and two groups of old adults performed one of two high-demanding conditions, in w…
A Psychometric Evaluation of the Group Environment Questionnaire in a Sample of Professional Basketball and Soccer Players
2013
Psychometric properties of the Group environment Questionnaire were investigated in a large sample of soccer (n = 222) and professional basketball players (n = 375). Confirmatory factor analysis was performed both on the total sample and on the two sub samples through a multi-group approach; associations between cohesion and the duration of belonging to the team were also explored. Results confirmed the four-factor structure proposed by Carron's original model even though some items with low loadings were eliminated. No signifcant associations were found between team cohesion and the duration of belonging to the team. © Perceptual & Motor Skills 2013.
The Dimensions of Facebook Addiction as Measured by Facebook Addiction Italian Questionnaire and Their Relationships with Individual Differences
2017
Abstract The studies reported analyze the factorial structure of Facebook Addiction Italian Questionnaire (FAIQ), a variant of 20-item Young's Internet Addiction Test (IAT). In Study 1, we tested FAIQ psychometric properties using exploratory factor analysis (EFA). In Study 2, we performed a confirmatory factor analysis (CFA) to verify the FAIQ factorial structure identified through EFA. Results from CFA confirm the presence of a four-factor model accounting for 58 percent of total variance, plus a general higher order factor that best fits the data. Further relationships between FAIQ factor scores, personality, and Facebook usage have been explored.
A study of temporal estimation from the perspective of the Mental Clock Model.
2009
M. Cardaci's (2000) Mental Clock Model maintains that a task requiring a low mental workload is associated with an acceleration of perceived time, whereas a task requiring a high mental workload is associated with a deceleration. The authors examined the predictions of this model in a musical listening condition in which musical pieces were audible in several structural complexities. To measure the effects of musical complexity on time estimation, the authors used retrospective and prospective time-estimation paradigms. For the retrospective paradigm, the authors invited participants to listen to a musical piece and then estimate its duration. For the prospective paradigm, the authors invit…
Frequency format facilitates reasoning in simple numerical tasks.
2005
This study examined whether it is easier to reason in terms of frequencies or with percentages for simple numerical tasks. Research on probabilistic reasoning has shown that humans can draw correct inferences when problems are presented in terms of natural frequencies but not when in percentages. Whether the same effect can be observed in other numerically simple tasks which are not probabilistic was studied with 40 undergraduate students who volunteered for the experiment (13 men, 27 women; M age of 23 yr.). In a simple numerical task involving frequencies or percentages ( N = 20), their performance showed representation in frequencies facilitates the task.
Cardiovascular Management Self-efficacy: Psychometric Properties of a New Scale and Its Usefulness in a Rehabilitation Context.
2015
Self-efficacy beliefs have been shown to affect various effective health-promoting behaviors in patients. Unfortunately, availability of reliable and valid measures of self-efficacy in cardiovascular diseases (CVDs) is still very limited. Background: Self-efficacy beliefs have been shown to affect various effective health-promoting behaviors in patients. Unfortunately, availability of reliable and valid measures of self-efficacy in cardiovascular diseases (CVDs) is still very limited. Purpose: The aims of this study were to present a new scale measuring self-efficacy beliefs in managing CVD and to examine its psychometric properties. Methods: The study involved 172 patients (mean age = 66.4…
Predicting depression from illness severity in cardiovascular disease patients: self-efficacy beliefs, illness perception, and perceived social suppo…
2014
Background: Many studies have investigated the relationships between cardiovascular diseases and patients' depression; nevertheless, few is still known as regard the impact of illness severity on depression and whether psychosocial variables mediate this association. Purpose: The aim of this study is to investigate the putative mediating role of illness representations, self-efficacy beliefs, and perceived social support on the relationship between illness severity and depression. Methods: A total of 75 consecutive patients with cardiovascular disease (80 % men; mean age=65.44, SD=10.20) were enrolled in an Italian hospital. Illness severity was measured in terms of left ventricular ejectio…
The influence of illness severity on health satisfaction in patients with cardiovascular disease: The mediating role of illness perception and self-e…
2015
The importance of psychological factors in improving conditions of cardiovascular disease (CVD) patients is stressed by the guidelines for their prevention and rehabilitation, but little is known about the impact of illness severity on patients well-being, and on the psychosocial variables that may mediate this association. The aim of this study was to investigate the role of illness perception and self-efficacy beliefs on the relationship between illness severity and health satisfaction in 75 CVD patients undergoing rehabilitation (80% men; mean age = 65.44) at the St. Luca Hospital, Istituto Auxologico Italiano, Milan, Italy. Illness severity was measured in terms of left ventricular ejec…
Is more choice always worse? Age differences in the overchoice effect
2015
ABSTRACTCurrent research on the overchoice effect has been mainly conducted from an adult point of view and with adult subjects. This study investigates whether children, adolescents, and seniors suffer the same negative consequences as adults when facing an overabundance of choice. Findings showed that the overchoice effect did not equally extend to all age groups. While adolescents were affected by the phenomenon in a very similar way as adults, children and seniors suffered fewer negative consequences of an overabundance of choice. Theoretical and practical implications are discussed.
