Some differences between phonetic and auditory modes of perception

When third-formant transitions are appropriately incorporated into an acoustic syllable, they provide critical support for the phonetic percepts we call [d] and [g], but when presented in isolation they are perceived as time-varying ‘chirps’. In the present experiment, both modes of perception were made available simultaneously by presenting the third-format transitions to one ear and the remainder of the acoustic syllable to the other. On the speech side of this duplex percept, where the transitions supported the perception of stop-vowel syllables, perception was categorical and influenced by the presence of a preposed [al] or [ar]. On the nonspeech side, where the same transitions were heard as ‘chirps’, perception was continuous and free of influence from the preposed syllables. As both differences occurred under conditions in which the acoustic input was constant, we should suppose that they reflect the different properties of auditory and phonetic modes of perception.     

Issues in treatment efficacy research with alcoholics.

A variety of therapeutic strategies have been used in the treatment of alcoholic patients. Within this context, behavioral techniques have been widely employed with varying degree of effectiveness. This paper attempts to explore theoretically 2 widely used behavioral therapeutic methods, systematic desensitization and covert sensitization, along with traditional insight-oriented therapy. Possible merits and limitations of applying these treatment approaches to alcoholic patients are explored.     

Use of a “balance-sheet” procedure to improve the quality of personal decision making: A field experiment with college applicants

This study tested the effectiveness of a “balance-sheet” or tallying procedure used to induce high school seniors to think carefully about considerations relevant to their choice of college. Students who were exposed to the balance-sheet procedure three months before their choice of college were compared with a control group six weeks after making their decision. In comparison with control subjects, students administered the balance-sheet procedure tended (though the findings were not always significant at the 0.05 level) (1) to select a wider array of alternatives in formulating the decision, (2) to take into account more self-related and fewer social considerations, (3) to express less regret and report less concern about their choice following the decision, and (4) were less interested in receiving supportive, dissonance-reducing information. The balance-sheet procedure appears to make salient the importance of the decision, helps clarify the merits of the choice alternatives, and stimulates a search for feasible alternatives.     

Factor Composition of the Suicide Intent Scale

An exploratory analysis of the Suicide Intent Scale was performed on a sample of 98 psychiatric inpatients who had made suicide attempts. The factor analysis was performed using a method for polychotomous data, and resulted in a two-factor solution. The Lethal Intent factor contained items pertaining to the subjective level of lethal intent, while the Planning factor contained items largely related to objective planning for the attempt. Preliminary analysis of these factors suggest that the Suicide Intent Scale can be used to evaluate two separate aspects of suicidal behavior.     

Friendship,Depression, and Suicide Attempts in Adults: Exploratory Analysis of a Longitudinal Follow‐Up Study

Social support is thought to protect against the risk of suicidal behavior in young people and late life, but less is known about the role of friendship in adults. We explored the effect of friendship on suicide attempt risk during 1‐year follow‐up of 132 adults presenting with major depressive episode (MDE). Items from the Social Adjustment Scale–Self‐Report were used as an index of frequency and quality of recent friendship contacts. Survival methods tested associations of friendship with risk of suicide attempt, recurrent MDE, and related outcomes during follow‐up. Impaired friendship predicted greater risk of suicide attempt in an unadjusted Cox model. This association was stronger for quality (p = .009) than frequency (p = .081) of friendship contacts. In the adjusted model, the effect of friendship on suicide attempts was largely explained by self‐reported depression severity. Friendship has a potentially bidirectional relationship with depression, and its effect on suicidal behavior appears to occur through its relationship with depression. Future research should examine the effect of antidepressant treatment on friendship and be designed to test mediation models of relationships between friendship, depression, and suicidal behavior.
