Semantic distance effects in naming superordinates

The time to select a superordinate label in response to a target word is shown to be a function of the normative likelihood of the target being produced as an exemplar of the superordinate. This extends the scope of semantic distance effects to a new task situation. The effect declines with practice (repetition) and is also reduced by other preceding tasks. Two alternative accounts of the processing underlying selection are discussed.     

Errors in auditory direction-finding after compensation for visual re-arrangement

Ss walked about out of doors wearing laterally displacing prisms, and sound-attenuating muffs. Errors occurred in an auditory localization task during exposure to visual displacement. With continued exposure these errors tended to disappear after about 108 min. The errors disappeared earlier when muffs were not worn.

Early interactions and the socioemotional development of deaf infants

Studies of the early face-to-face interactions and later attachment behaviours between infants and their caregivers are reviewed, with a particular focus on implications for deaf infants. Since the majority of deaf infants are born to hearing parents, it is to be expected that many parental responses will rely on vocalizations which are inaccessible to the deaf infant. Are other sensory modalities enhanced or used in a compensatory manner by hearing parents so as to make their communication with a deaf infant more effective? Is the deaf infant's heightened need for visual and tactile input adequately met during normal interactions with their caregivers? Does the deaf infant develop the same strategies for signalling distress and coping with separation as does the hearing infant? Although the research literature on this population is sparse, there are beginning to be more reports addressing these questions as early identification becomes increasingly possible. Therefore, this paper will cover issues of the role of eye contact and mutual coordination in early interactions, compensatory parenting behaviours from the perspective of the ‘intuitive parenting’ model, and precursors to later attachment behaviours in deaf infants.     

Theory-based screening for prevention: Focusing on mediating processes in children of divorce

Prevention programs in mental health theoretically can benefit from selecting participants who have a greater likelihood of developing psychological problems because of their exposure to the putative mediators targeted for change in an intervention. Screening on mediators may increase statistical power to detect program effects, enhance the cost-effectiveness of intervention trials, and decrease the possibility of iatrogenic effects. The circumstances that optimize the strategy of screening on the basis of mediating variables are discussed, and data are presented to illustrate the development of a mediational selection strategy to identify families who might best benefit from a preventive intervention for children of divorce. In addition, we present evidence that adjustment problems for children experiencing a divorce, as with most mental health problems, are not the result of one specific factor, but are jointly determined by several mediating processes that occur subsequent to the divorce. The mediational selection strategy developed illustrates the utility of measuring a set of mediational processes central to conferring risk for mental health problems to children of divorce.
