re simultaneously presented. This may lead to the assumption that visual stimuli is preferable to auditory stimuli, and yet findings from this study show that this is not always the case. Thus the school psychologist will need to consider each case for characteristics related to the individual and the visual stimuli. These findings can be applied to the school setting, more so than the findings from the Roberts et al. (2001) and Eisenmajer et al. (1998), however they are less applicable than findings from Heimann, et al. (1995).
The authors presented adequate background information to support the need for this study, and the study design was appropriate. The method of analysis was also explained regarding the hypotheses. While the article was presented in a clear manner, and the discussion did compare findings to previous research, implications and applications of findings was lacking.

"Receptive and Expressive Communication Development of Young Males With Fragile X Syndrome," by Roberts, Mirrett, and Burchinal (2001). The authors stated that Fragile X syndrome is a common inherited cause of mental retardation for males and research has pointed out that a broad spectrum of communication problems exist for this group. It has also been shown that cognitive deficits tend to become greater in later childhood/adolescence. Thus it has been suggested that greater delays may be found in young males as they get older, however it is not known whether there are greater expressive or receptive communication deficits in young children and the age at which these deficits appear. This information is needed for adequate timing and focus of interventions, implying the need for the current study.
For this study 39 males ages 20 to 86 months of age with fragile X syndrome were...
