Spatial frequency masking in positive- and negative-symptom schizophrenia.

The role of transient and sustained channels in masking was investigated in groups with positive and negative symptoms in schizophrenia and in a control group. The target stimulus was a 3.0 c/deg sinusoidal grating, which was masked at 11 stimulus-onset asynchronies between -40 to 360 ms by a 1.0 c/deg mask or an 11.0 c/deg mask. The results showed that there was no difference between the control and positive-symptom groups in the perception of the 3 c/deg target stimulus, nor was there a difference when the target was masked by 1 or 11 c/deg masking stimuli. In comparison with the control and positive-symptom groups, the negative-symptom group showed a significantly higher threshold for the perception of the 3 c/deg target stimulus and more masking with a 1 c/deg mask, but not with an 11 c/deg mask. The results provide evidence for distinguishable differences in visual masking between groups with positive and negative symptoms in schizophrenia.

The assessment of reading readiness using multidimensionally scored time-compressed speech.

Normal-hearing children (39 M, 36 F) from a monolingual environment, aged 5 yrs 10 mo to 7 yrs 2 mo, of average or better intelligence, were selected as being at high, average, or low risk of reading readiness according to scores on the Lindamood Auditory Conceptualization (LAC) test. Ss were also given the Stephens Oral Language Screening Test (SOLST), emphasizing syntactical development. Ss were then tested for verbal respeating of taped 5-word sentences and 5-word 1st-order sentential approximations at 32 db SL re SRT. Stimuli were presented at 0, 40, or 60% time compression (TC). Responses were scored right/wrong and also by Porch's multidimensional system involving repeats and cues. For both systems significant effects were obtained between a number of TC conditions vs both the LAC and SOLST. The LAC appeared to emphasize phonetic units, the SOLST linguistic units in real sentences. The TC condition appeared to emphasize linguistic units at both word and sentence levels, less so with increasing TC. Results supported the usefulness of the TC stimuli in assessing reading readiness and it was suggested that the various stimuli assess different aspects of auditory processing.

After "Humanae Vitae": a decade of "lively debate.".

In the decade since Humanae Vitae, dissenting Catholic moral theologians have objected to treating the biological structure of the marital act as normative. Pluralism both in ethical methodologies and in specific teachings is developing. This article discusses one example of this trend in Human Sexuality, a study commissioned by the Catholic Theological Society of America, which posits creative growth toward integration as the principle from which values and norms are to be derived.
