The Kahn Test of Symbol Arrangement: a suggested index for specific learning disabilities

An index for specific learning disabilities of six signs or symptoms, taken as a group, is described. Preliminary work encourages cross-validation.     

Relative and Absolute Judgments of Speech Rate from Masked and Content-Standard Stimuli The Influence of Vocal Frequency and Intensity

In two previous studies, the perception of speech rate was found to be positively related to the vocal frequency and intensity of speech. In those studies, a single sample of spontaneous, content-masked speech was used to produce nine stimuli by factorially varying three levels of each vocal frequency and intensity, while controlling the actual speech rate of the stimuli. Participants were asked to judge each stimulus, preceded by a standard, “anchoring,” stimulus as to its speech rate, pitch, loudness, and duration. The purpose of the three studies reported here was to examine the generalizability of the previous findings by using stimuli that were nonmasked and/or were not preceded by an anchoring stimulus. In each study, nine speech stimuli were prepared, as described above, and participants were asked to make judgments about the rate, pitch, loudness, and duration of each stimulus. In the first study, the stimuli were masked but were not preceded by an anchoring stimulus. In the second study, participants listened to content-standard speech stimuli preceded by an anchoring stimulus. Finally, in the third study, content-standard stimuli without an anchoring stimulus were used. In addition, studies two and three used speech segments of a male and a female speaker. The findings from the three studies replicated the central findings of the previous studies. They suggest, in other words, that rate perception of speech is indeed influenced by vocal frequency and, to some extent, by intensity, and that these relationships are not materially altered by the speakers'gender.     

Clinicians' Attitudes Toward No-Suicide Agreements

Though no-suicide agreements are widely used and often recommended for suicidal patients, their sparse empirical support leads to questions regarding their use with patients of various ages. To answer this question, 46 licensed psychologist members of a Southern state psychology association answered questions regarding their beliefs and attitudes about no-suicide agreements. Such agreements were considered more appropriate for adults or adolescents than children. They were judged highly appropriate with moderately suicidal patients and were expected to help patients postpone suicide until after a crisis had past and to help reduce clinicians' anxiety.     

Reducing prejudice via direct and extended cross-group friendship

One of the most exciting developments in intergroup contact theory is the idea that a certain type of contact, cross-group friendship, might be particularly effective at reducing prejudice. In this chapter we review research on two types of cross-group friendship. Direct cross-group friendship refers to friendships that develop between members of different groups. Extended cross-group friendship, on the other hand, refers to vicarious experience of cross-group friendship, the mere knowledge that other ingroup members have cross-group friends. We consider the relationship between both types of cross-group friendship and prejudice and the processes that mediate and moderate these relationships. The research highlights the respective strengths and weaknesses of direct and extended cross-group friendship and illustrates how they might be practically combined in efforts to improve intergroup relations.
