Dichotic interactions of speech sounds and phonetic feature processing

Identification of CV syllables was studied in a backward masking paradigm in order to examine two types of interactions observed between dichotically presented speech sounds: the feature sharing effect and the lag effect. Pairs of syllables differed in the consonant, the vowel, and their relative times of onset. Interference between the two dichotic inputs was observed primarily for pairs which contrasted on voicing. Performance on pairs that shared voicing remained excellent under all three conditions. The results suggest that the interference underlying the lag effect and the feature sharing effect for voicing occur before phonetic analysis where both auditory inputs interact.     

Memory-enhancing characteristics of client-recalled important events in cognitive and experiential therapy: Integrating cognitive experimental and therapeutic psychology

In an attempt to encourage further integrative theorizing and experimental work across cognitive and therapeutic psychology, characteristics of therapeutic events that might contribute to their ‘memorableness’ were examined. Scales that rate five ‘information processing’ characteristics of therapeutic events were employed to score such characteristics of 55 client-identified important and 55 matched control events taken from actual therapeutic sessions of both cognitive and experiential psychotherapies. Results indicated that scales scoring the ‘depth’, ‘elaborateness’, and ‘conclusion-orientation’ of therapeutic dialogue during the events examined tended to discriminate reliably and as predicted between client-identified important and control events, particularly when ratings of therapist talking turns were examined. Limited support also was found for a second prediction based on Paivio's (1986) dual coding theory of memory concerning different patterns of results for cognitive versus experiential therapeutic events. Suggestions are offered for further research on human memory for specific events in therapeutic and other areas of applied psychology.     

Mentoring Among Women Lawyers1

Considerable controversy exists as to both the nature and efficacy of mentoring among women professionals. As noted by Wrightsman, this controversy persists largely because researchers have failed to use a common scientific definition of the concept. In the present research a survey of existing studies was used to set a more stringent criterion of mentoring than that usually employed. Data were then gathered from a sample of women lawyers in the State of Oregon. Results indicated that those meeting the more stringent criterion perceived themselves as more successful and satisfied in their careers than those not meeting it. Those women who said that they had mentors but who did not meet the criterion reported themselves as less successful and satisfied than those who claimed to have a mentor and met the criterion. These results are seen as demonstrating the value of the more stringent criterion as well as the possible value of true mentors to women professionals.     

A Comparative Evaluation of Police Suicide Rate Validity

The authors assessed sensitivity, specificity, and predictive value of official police suicide rates and compared them to municipal workers. Deaths officially classified as suicide, accidental, and undetermined were submitted to a panel of medical examiners for validation. Six cases originally in the accident and undetermined rubric were reclassified as suicide. Official police suicide rates had less sensitivity (83.3% compared to 92.3%) of actual suicides than municipal worker rates. Police suicide rates also showed a lower negative proportion than municipal worker rates (86.2% compared to 98.7%). A generalizable sensitivity proportion equation for assessing suicide rates in other police groups is presented.     

Ipsilesional Arm Aiming Movements After Stroke: Influence of the Degree of Contralesional Impairment

The authors examined the effects of the degree of impairment of the contralesional upper limb and the side of the hemispheric damage on ipsilesional upper limb performance in chronic stroke individuals. Right- and left-side stroke resulting in mild-to-severe impairment and healthy participants took part in simple and choice reaction time tasks involving aiming movements. The stroke individuals performed the aiming movements with the ipsilesional upper limb using a digitizing tablet to ipsi- or contralateral targets presented in a monitor. The global performance of the group with severe right hemispheric damage was worse than that of the other groups, indicating that the side of hemispheric damage and degree of motor impairment can adversely affect aiming movement performance.
