Factor structure of an Arabic translation of the scale, preference for numerical information

An Arabic translation of Viswanathan's 1993 scale, Preference for Numerical Information, was administered to 157 tenth-grade students (M age = 16.1 yr.) in the United Arab Emirates. Analysis showed that the scale was homogeneous as the factor solution was comparable to that reported in the original study and item scores were moderately correlated with total scores when used in a different cultural setting.     

A mathematics content course and teaching efficacy beliefs of undergraduate majors in education

This study was designed to assess the mathematics teaching efficacy beliefs of undergraduates in elementary education through a manipulative-based course in mathematics. Responses of 106 university undergraduates to the 21-item Mathematics Teaching Efficacy Beliefs administered as pre- and posttest without a control group showed a significant immediate postcourse change in their efficacy beliefs using dependent t test.     

Hand-foot motor priming in the presence of temporary inability to use hands

To verify if the link between observed hand actions and executed foot actions found in aplasics is essentially induced by the constant use of foot substituting the hand, we investigated if the vision of a grasping hand is able to prime a foot response in normals. Participants were required to detect the time-to-contact of a hand grasping an object either with a suitable or a less suitable movement, an experimental paradigm known to induce a priming effect. Participants responded either with the hand or the foot, while having free or bound hands. Results showed that for hand responses motor priming effect was stronger when the hands were free, whereas for foot responses it was stronger when the hands were bound. These data are interpreted as a further evidence that a difficulty to move affects specific cognitive functions and that the vision of a grasping hand may prime a foot response.     

Newborns' preference for goal-directed actions

The central role of sensory-motor representations in cognitive functions is almost universally accepted. However, determining the link between motor execution and its sensory counterpart and when, during ontogenesis, this link originates are still under investigation. The aim of the present study is to investigate whether at birth this link is already present and 2-day-old newborns are able to discriminate between visual cues indicating goal-directed or non-goal-directed actions. Here, with a preferential looking technique, a hand grasping a ball was the observed movement and we orthogonally manipulated the three factors necessary to successfully reach the goal: (a) presence of the ball, (b) direction of the arm movement, and (c) hand shaping. Results indicated that newborns orient more frequently and look longer at a hand shape for whole hand prehension but only when the movement is directed away from the body and toward the external world. In addition, newborns prefer the away from the body movement only when the object is present. We argue that newborns prefer a movement directed toward the external world only when it may develop into a purposeful movement because of the presence of the to-be-grasped object. Overall, our results support the existence of primitive sensory-motor associations since the first days after birth.     

Training Methods for Delivering Difficult News in Genetic Counseling and Genetics Residency Training Programs

Genetic counselors and clinical geneticists are often in the position of delivering difficult news (DDN) to patients and families. Many studies show that healthcare providers require major improvement in the skills needed in DDN in a manner that is satisfactory to their patients. The purpose of this study was to assess the amount and methodology of DDN training received by genetic counselors and medical genetics residents in their training programs, such as observations of DDN or attending didactic lectures. To our knowledge, there is no previous assessment or study of DDN training in genetic counselor and medical genetics residency programs; therefore, we aim to both assess and compare the training in DDN received by genetic counselors and by genetics residents and determine whether there is a desire for recommendations on DDN training. We invited genetic counseling (GC) and genetics residency program directors to participate in an online survey designed to assess coursework, clinical experiences, and directors’ attitudes toward teaching DDN. Response rate was 85% (28/33) for GC program directors and 26% (14/53) for genetics residency program directors. One hundred percent of GC and genetics residency directors who responded to the survey agreed that it is important for genetic counselors and medical geneticists to be able to deliver difficult news effectively and that training programs should formally teach students how to deliver difficult news. Six of the eight common teaching methods are used by at least 75% of GC programs while two of eight are used by at least 75% of genetics residency programs. Seventy-nine percent of GC and 93% of genetics residency program directors agree that there should be recommendations on how to teach students to deliver this news. Our results show that techniques for DDN are integrated more fully into GC program curricula than genetics residency curricula. Directors of both types of programs desire recommendations and more standardized education for training students to deliver difficult news.     

Mathematics anxiety among eighth-grade students of the United Arab Emirates.

To investigate the mathematics anxiety of 159 students in Grade 8 (M age = 14.3 yr.) in the United Arab Emirates a 28-item anxiety scale was administered. Analysis indicated some mathematics anxiety. Also, boys and girls scored significantly differently as boys had the higher mean.     

An evolutionary hypothesis for obsessive compulsive disorder: a~psychological immune system?

A new hypothesis is presented within the framework of evolutionary psychology that attempts to explain the origins of obsessive-compulsive disorder. It is suggested that obsessions and compulsions originate from the overactivity of a mental module that the majority of humans possess and has the function of generating risk scenarios without voluntary intervention. It is hypothesised that obsessional phenomena function as an off-line risk avoidance process, designed to lead to risk avoidance behaviour at a future time, thus distinguishing it from anxiety and related phenomena as on-line emotional states, designed to lead to the avoidance of immediate and direct risks. Finally, the hypothesis makes a number of specific predictions that are testable and refutable. It is contended that the present hypothesis if supported by empirical evidence could serve as a basis for future research on this important disorder.
