Outcome predictors in the behavioral treatment of stuttering

The MMPI and subscales of the Stuttering Severity scale were utilized to predict motivation and success in the behavioral treatment of 32 stutterers. Subjects spent a mean of 10 individual sessions in criterion-oriented learning of fluent speech based on speech-muscle relaxation aided by EMG visual biofeedback. Judged motivation and judged success were strongly related to each other and significantly related to MMPI K and Es scores and negatively to F and Sc. Actual success was negatively related to Sc and Pd, completely unrelated to Es, and (if anything) negatively related to K. Results are consistent with previous studies, and show that global judgements of progress were only minimally related to a measure of actual progress.     

Hominid evolution, supralaryngeal vocal tract physiology, and the fossil evidence for reconstructions.

The functional, physiologic aspects of the human supralaryngeal vocal tract, which follow from the equal length of the oral and pharyngeal cavities and their right angle orientation are discussed. Sounds like the vowels [i] and [u], which only the human supralaryngeal vocal tract can produce in a Quantal mode, provide a selective advantage for vocal communication and the evolution of the human vocal tract and matched neural property detectors. The dissimilarity between Neanderthal skulls and specimens of anatomically modern Homo sapiens and other fossil skulls is discussed in relation to the reconstruction of the Neanderthal supralaryngeal vocal tract. The absence of some of the innate neural property detectors that play a part in the perception of human speech can be inferred in Neanderthal hominids from the reconstruction of their supralaryngeal vocal tract.     

Depth of nontarget processing in an attention task

Two studies examined the effect of the sensory discriminability of targets from nontargets on depth of nontarget processing. Subjects shadowed target words that were binaurally presented with coincident nontarget words. Targets and nontargets were spoken in the same male voice under low sensory discriminability and in male and female voices, respectively under high sensory discriminability. Across the two studies, depth of nontarget processing was assessed in three ways: extent to which shadowing accuracy was disrupted by a semantic overlap between targets and nontargets, expenditure of capacity (reaction time to subsidiary light signals), and nontarget recall. All three possible measures of depth of nontarget processing decreased as sensory discriminability increased. The data support the assumption of multiple-loci theories of attention that nontargets can be perceptually inhibited; they contraindicate the assumption of late-selection theories that perceptual processing is automatic and irrepressible.     

Drug-preexposure effects in flavor-aversion learning: associative interference by conditioned environmental stimuli

Previous research has documented that exposure to a drug reduces the ability of the drug to support subsequent flavor-aversion learning. The four experiments reported here examined the hypothesis that this drug-preexposure effect is due to associative interference from environmental stimuli associated with the drug effects during preexposure. When distinctive environmental stimuli (confinement in a black compartment) were present during drug preexposure, these stimuli significantly disrupted subsequent flavor-aversion learning. Furthermore, flavor conditioning was not significantly disrupted when drug preexposure occurred in the absence of salient environmental stimuli or when the previously conditioned environmental stimuli were extinguished prior to flavor conditioning. It is significant, and in contrast to other published research, that flavor conditioning was not disrupted when the distinctive cues paired with the drug during preexposure were absent at the time of the flavor-drug pairing. These results are thus consistent with results from conventional studies of stimulus blocking and suggest that associative processes can play a major role in the drug-preexposure effect.     

The effects of alcohol and extreme provocation on the use of a highly noxious electric shock

Intoxicated and nonintoxicated subjects were given the opportunity to administer a potentially injurious level of shock to an opponent who behaved in either a provocative or an extremely provocative manner. The provocative opponent attempted to administer high-intensity shocks to the subject. The extremely provocative opponent attempted to administer high-intensity shocks and the potentially injurious level of shock. The intoxicated subjects in the extreme provocation condition evidenced the greatest increase in the use of the potentially injurious shock. It was concluded that aggression is a function of the interaction of alcohol consumption and level of provocation.     

Consulting for Change: Anatomy of an Effort That Failed

Theoretical issues concerning the process of change and the phenomenon of resistance are highlighted in this analysis of opposition observed during in-service training of high school and junior high school counselors. Behavioral examples are examined with reference to the principles found in current change theory-theory that suggests generalizations and practical considerations for the would-be change agent, whether counselor, consultant, or social psychologist.     

Some correlates of women's Self-Image and Stereotypes of Femininity

An expanded version of the Gordon Self-Image and Stereotypes of Femininity scale was administered to a sample of 362 female nursing personnel. Factor structure of the scale was found to closely approximate that of the Gordon sample. Numerous significant relationships of self-image dimensions to affective responses, experienced role stresses, demographic measures, and personality indices were isolated. However, perceptions of males' image, doctors' image, and own image of a feminine woman were generally unrelated to these measures. Further, examination of discrepancies between self-image dimensions and self and others' stereotypes of a feminine woman along these dimensions did not aid in explaining variance in affective responses or experienced role stresses. Implications of the findings are discussed and suggestions for future research are presented.     

Partial death as a defining characteristic of a subculture

This paper presents a discussion of the idea of "partial death" as it relates to the subculture of the beats or hypsters, especially in San Francisco, from about 1948 to 1964, with special emphasis on the works of Kerouac and Ginsberg and a study by Rigney and Smith.
