The physician's influence on patients' choices

Although the traditional physician ethic sees nothing objectionable about the doctor's influence over patients, superficial conceptions of the patient's right to self-determination imply that this influence may be manipulative. On the contrary, there are several different lines of argument which can reconcile self-determination with the physician's influence. Nevertheless, drawing the boundaries between legitimate methods of persuasion, and manipulation or coercion sometimes proves difficult.     

Evidence for disparity change as the primary stimulus for stereoscopic processing

Subjects were able to respond to a lens-induced stereoscopic slant more quickly and more accurately when it was imposed on only part of a surface rather than on the whole surface. This shows that the presence of a stereoscopic boundary, where disparity is discontinuous, increases the efficiency of stereoscopic processing. This finding is not consistent with many current models of stereopsis.     

Typicality ratings for 893 exemplars of 93 categories

Although the typicality effect has been much studied in the semantic memory literature, typicality ratings exist for exemplars from only a very limited number of categories. This lack of ratings frequently limits the range of stimuli that can be used in investigations of the typicality effect. As an aid in stimulus construction, this paper reports typicality ratings of 893 exemplars from 93 different categories.     

Postnatal development of respiratory and vocal responses during aversive classical conditioning in cats

Respiratory rate, respiration amplitude, and vocal responses were recorded in cats of different ages during classic conditioning. Vocal responses to the conditional stimulus (CS) appeared first in 8-week-old kittens, and became prominent at older ages. An increase in respiration rate occurred after the onset of the CS in cats of all ages. Similarly, the decrease of respiration amplitude was observed at all ages, but only in 8-week-old and older subjects did this response resemble an adult pattern. In 4-week-old kittens the response was characterized by an early and brief peak, suggesting an alpha conditional response (CR). Clear and significant discrimination between a warning and a safety signal was present in both respiratory and vocal responses after the age of 8 weeks.     

The locus of intersensory facilitation of reaction time

When an imperative visual stimulus is paired with an auditory (accessory) stimulus, RT is generally faster than with the imperative stimulus alone. Three experiments using additive-factors logic tested an energy-summation view of the accessory, where effects are due to increased rate of information build-up in sensory stages, and a preparation-enhancement view which holds that the accessory serves an alerting function. Experiment 1 found no interaction between the accessory presence and (visual) stimulus brightness, suggesting no role of the accessory in stimulus identification. Experiment 2 found no interaction between accessory presence and spatial S-R compatibility, arguing that the accessory operated in stage(s) other than response selection. Experiment 3 produced an interaction between the accessory and movement complexity, arguing for accessory effects in a response-programming stage. The data generally favored preparation-enhancement, and offered no support for an energy-summation view.     

Cognitive dissonance as a mechanism in vocational decision processes

This study examined changes in cognitive-dissonance-related variables during the professional training period. Differences in levels and change in satisfaction with career choice, importance of career, certainty of career decision, self-occupational perceptions, general attitude toward career, time since career decision, and past experience were observed when students who left a collegiate professional training program before program completion were compared with those who remained in the program. Data supports the validity of D. Hershenson and R. Roth's (1966, Journal of Counseling Psychology, 13, 368–370) and V. Harren's (1979, Journal of Vocational Behavior, 14, 119–133) theoretical models of vocational decision and the Assessment of Career Decision Making scale.     

Self-reported assessment practices of school psychologists: Implications for training and practice

This study reports the results of an investigation of the assessment views and practices of school psychologists in the United States. Results of the investigation indicated that respondents are predominantly behavioral and cognitive behavioral in orientation; spend most of their professional time in the public schools; and engage in a great deal of assessment. Behavioral assessment and projective testing occupies the greatest amount of their social-emotional assessment time. Behavioral interviewing is the most used behavioral technique, followed by behavioral observation, which is reportedly used by approximately one third of the respondents with from 41% to 100% of clients. Although most of the respondents report a preference for continuing to do approximately the same amount of the various social-emotional assessment activities as they are presently doing, very high percentages of respondents indicate that their use of behavioral assessment strategies would increase with development of published instrumentation, normative standards, and standardized out-of-setting behavioral procedures.     

Henry Freund: 1896–1982

Dr. Henry Freund was one of the foremost authorities on stuttering in Europe, and his contributions on the psychology of the disorder continued after emigrating to this country. He was a neurologist and psychiatrist, as well as a speech pathologist. He died in 1982, and in this posthumous paper he describes his career and personal experiences, while undergoing therapy from the most famous European speech pathologists of his time. He also offers some cogent comments about current therapies and future needs.
