The moderating role of attachment styles on the relationship between alexithymia and interpersonal problems was assessed in the present study. Eight hundred and twenty nine Iranian general populations (372 men, 457 women) who were living in Tehran were involved in this study. The participants were asked to complete three questionnaires including Adult Attachment Inventory, Toronto Alexithymia Scale-20, and Inventory of Interpersonal Problems. Results showed a significant negative correlation between secure attachment style and interpersonal problems. Moreover, the results revealed that avoidant and ambivalent attachment styles as well as alexithymia had a significant positive correlation with interpersonal problems. Regression analysis indicated that attachment styles have a moderating role on the relationship between alexithymia and interpersonal problems. It can be concluded that the relationship between alexithymia and interpersonal problems is not a simple linear one. This is partly moderated by attachment styles.

Despite the innovations in automatic train control (ATC) systems to reduce the risk of driver error, many rail accidents still occur due to defects in these systems, emphasizing the essential role of the driver in preventing rail accidents and proper control of the train. This paper studies the influence of drivers’ cognitive performance, including attention and visual perception, on the occurrence of rail accidents. The research is conducted using so-called Ex-Post facto method on a random sample of 56 train drivers with a minimum of three years of experience. The research instruments included drivers’ cognition test system including WAFV (perception and attention function) sustained attention test, COG (cognitrone) selective attention test, LVT (visual pursuit) visual perception test, demographic questionnaire, and drivers’ safety history. Results of this research showed that there is no significant relationship between age and education level of train drivers, and rate of occurrence of rail accidents. A comparison on train drivers’ cognitive characteristics, between drivers with accident record(s) and those without, showed that the drivers who had experienced rail accident(s) had lower levels of sustained attention. However, no significant difference was found between the two groups in selective attention and visual perception. Investigating the association of drivers’ ages with their levels of sustained attention, the drivers with high levels of sustained attention were found to be significantly older than other drivers. According to practical implications of these findings, cognitive rehabilitation courses are recommended for train drivers to attenuate the risk of rail accidents.
