Screening for language problems in minority preschool children is not straight-forward because of these children's diverse cultural, economic, and linguistic backgrounds. Over 68% of the 540 preschool English-speaking children in the Fort Worth Head Start program obtained scores at least one standard deviation below the mean on the Hannah-Gardner Test of Verbal and Nonverbal Language Functioning. This high failure rate suggested that a local adaptation was needed for language screening. The procedures used to calculate local norms and other issues involved in screening minority population are discussed.

An increase in LH secretion was induced in ovariectomized oestradiol benzoate-primed rats 5 h after a second injection of oestradiol benzoate. Lesions stereotaxically placed in the cortical and basomedial amygdala of steroid-primed rats abolished this rise. The results provide evidence for a facilitatory action of the amygdala upon LH release and an involvement of this region of the limbic system in oestrogen-feedback mechanisms.
