Thresholds of Illumination for the Visual Discrimination of Direction of Movement and for the Discrimination of Discreteness

Currently, relatively little is known about what drives the choice of limb for goal-oriented reaching. Traditionally, the explanation has been tied predominately to motor dominance as manifested in handedness. This article offers data and an argument suggesting that handedness can be modified by attentional (spatial) information. Although motor dominance may be the controlling factor in the programming and execution of reaching movements at the midline and hemispace ipsilateral (same side) to the dominant limb, attentional information alters the programming of movements in what would be contralateral space. The general trend of behavior is characterized by reaching on the same side as the stimulus, in ipsilateral fashion, a phenomenon explained by kinesthetic efficiency and hemispheric bias.     

A Question of Foot Dominance

It is suggested that the popular definition of foot dominance (i.e., the limb preferred to execute a manipulative or mobilizing action while the other [nondominant] foot provides stabilizing support, e.g., kicking a ball) be reconsidered in light of understanding the functional characteristics of footedness and selected theoretical explanations. Relevance to future research designs and assessment methodology is discussed.

Marital Satisfaction and Quality of Father–Child Interactions: The Moderating Role of Child Gender

The authors aimed to investigate the prospective links between normative variation in fathers’ marital satisfaction and the observed quality of father–toddler interactions, as well as the moderating role of child gender in these associations. Sixty-three fathers reported on their marital satisfaction when their children were 15 months of age, and were observed interacting with their child at 18 months. The results suggested that marital satisfaction was positively associated with the quality of father–son interactions, while no relations emerged among fathers of girls. These findings reiterate the importance of marital relationships for the quality of fathers’ parenting, while reaffirming previous suggestions that the role of child gender in the marriage-parenting connections requires further investigation.
