Transfer of training for two ball-throwing tasks

The effects of training overhand ball throws to enhance underhand ball-throwing accuracy were studied with 921 Italian high school pupils (575 girls, M age = 16.5 yr., SD = 1.3; 346 boys, M = 16.5 yr., SD = 1.2) ages 14 to 18 years. A standardized test (10 underhand tennis-ball throws into the floor area delimited by an 80-cm radius wooden hoop lying on the floor 9 m from the standing pupil) was performed and scored. An Experimental group (435 girls, M age = 16.5 yr., SD = 1.3; 204 boys, M age = 16.5 yr., SD = 1.2) was randomly selected to participate in 10 weekly training periods. The set included 10 overhand throws of a rubber bouncing ball (14.5 cm diameter, weight 240 g) into a basketball hoop from 5 standardized positions (in front of the basketball hoop; at 45 degrees, 90 degrees on the right and on the left of the basketball hoop) at a distance of 4.40 m. The underhand test was repeated for both groups. On the average, boys obtained higher test scores than girls of the same age. Older adolescents had higher mean scores than younger adolescents. After 10 weeks, boys and girls of all ages improved. Mean differences between sessions were significant for the Experimental group (Student t test, p < .01). In Session 2, consistent differences between Experimental and Control groups were also found (Student t test, p < .05).     

Linguistic constraints on statistical computations: the role of consonants and vowels in continuous speech processing

Speech is produced mainly in continuous streams containing several words. Listeners can use the transitional probability (TP) between adjacent and non-adjacent syllables to segment "words" from a continuous stream of artificial speech, much as they use TPs to organize a variety of perceptual continua. It is thus possible that a general-purpose statistical device exploits any speech unit to achieve segmentation of speech streams. Alternatively, language may limit what representations are open to statistical investigation according to their specific linguistic role. In this article, we focus on vowels and consonants in continuous speech. We hypothesized that vowels and consonants in words carry different kinds of information, the latter being more tied to word identification and the former to grammar. We thus predicted that in a word identification task involving continuous speech, learners would track TPs among consonants, but not among vowels. Our results show a preferential role for consonants in word identification.     

Word length effect in early reading and in developmental dyslexia

Vocal reaction times were measured in Italian dyslexics and in proficient readers while they read single words. Three groups of control participants (for a total of 79) were tested. All were in the first, second or third grade of elementary school. Nine third graders with a low level of reading ability when assessed by standard reading procedures were also tested. Results indicated that vocal RTs of control participants were faster and less sensitive to word length as a function of age; also, there was a particularly marked change between first and second graders. Dyslexics' vocal RTs and errors were much worse than those of peer control participants and resembled those of first grade controls. It is suggested that normal readers in an orthographically transparent language (Italian) adopt a lexical strategy quite early in their learning. On the contrary, dyslexics seem unable to learn this mode of processing and continue to use a sub-lexical reading procedure.     

High cost helping scenario: The role of empathy,prosocial reasoning and moral disengagement on helping behavior

This study aimed to investigate the process that leads people to offer or omit help in response to an explicit request for assistance, taking into account both emotional and cognitive factors. Specifically, a hypothetical scenario methodology was used in a sample of 174 Italian youths (50% males) to examine whether and how factors such as empathy, prosocial moral reasoning and moral disengagement influence the propensity to help when providing assistance is not in the individual’s personal interest. While a few previous studies have included moral disengagement as an antecedent of prosocial decision making, we highlight the significance of this factor in the avoidance of moral responsibility towards others in need. The results highlight two ways in which differences in emotional tendencies and moral-cognitive processes may operate in prosocial decision making in high personal cost situations. First, high empathy levels could promote an altruistic response which in turn fosters mature prosocial moral reasoning. Second, personal distress may enhance moral disengagement mechanisms that may facilitate self-centred behaviors.     

Dispositional bases of self-serving positive evaluations

Positive orientation (POS) is the name given to the latent dimension common to self-esteem, optimism and life satisfaction. Earlier findings attest to the trait-like nature of POS and to its unique contribution to well-adjustment across domains of functioning. The present study investigates the extent to which POS accounts for individuals’ tendency to distort their self-assessment in a positive direction. Taking a class of students (N = 190) at the beginning of their academic year, POS predicted the individuals’ tendency to perform academically better-than-average (BTA) peers. POS accounted for BTA beyond what is merely due to self-esteem, life satisfaction and optimism.     

Time perspective as a predictor of problematic Internet use: A study of Facebook users

Time perspective (TP) has been related to different problematic human behaviors. The work presented in this paper assesses the role of time perspective in predicting problematic Internet use (PIU) by studying a sample (n = 149) of Facebook users. Participants (79 male, 70 female, mean age = 32.40, SD = 11.80) completed electronic versions of the Zimbardo Time Perspective Inventory (ZTPI) to assess their TP, and the Generalized Problematic Internet Use Scale 2 (GPIUS2) to assess their PIU. Results show that Past Negative and Present Fatalistic temporal frames are predictors of problematic Internet use, suggesting that time perspective is an individual difference construct that should be taken into consideration in the context of PIU.     

The Correlation Between Right-Wing Authoritarianism and Social Dominance Orientation: The Moderating Effects of Political and Religious Identity

In a secondary analysis performed on a representative sample of the Italian population (N = 887), we examined the correlation between right-wing authoritarianism (RWA) and social dominance orientation (SDO), analyzing the moderating effect exerted on such correlation by political interest and religion importance. RWA and SDO showed a positive, significant correlation (r = .38), moderated by political interest (which heightened it) and religion importance (which lowered it). Limits, implications, and possible developments of the research are discussed.
