Marital Status and Outcome in Patients with Coronary Heart Disease

The purpose of this study was to examine the relationship of marital status to health outcomes in 818 post-MI, coronary artery bypass surgery, and angioplasty patients (651 males, 157 females) from seven Northern California hospitals who completed 12 months of a nurse-managed, home-based multifactorial risk reduction program. Compared to married patients, nonmarried patients were significantly less likely to complete the program than married patients, more likely to smoke at baseline, and drank significantly less alcohol at baseline. At 12 months there were no significant differences between married and nonmarried groups on smoking cessation rates, HDL, LDL, triglycerides, or exercise treadmill test results. When patients were categorized as married, divorced, separated, widowed, or single, similar results were found for the analyses using two groups (married versus nonmarried), with the following exceptions. Separated patients were significantly less likely to quit smoking. In addition, separated patients showed significantly higher rates of starting (and continuing) to smoke during the time following their MI. Mortality was not significantly different between married and unmarried patients. Implications for intervention with separated patients and the importance of assessing both marital status and marital quality are discussed.     

Another View of Translation Manuals and the Study of Science

The article argues for the possibility of translation manuals having an implicit internal structure. This structure is composed of specific methodological assumptions and techniques. Using the (N)-type and (G)-type distinction developed by Fuller for the study of scientific behavior, it is shown that these are incomplete characterizations of translation manuals. A more complete characterization must involve an analysis of how the presence or absence of methodological rules influences the interpretation of specific research questions. It is further argued that while Quine's original indeterminacy thesis cannot be completely rejected, in some cases it can be modified to reflect the importance of the methodological constraints. Finally, it is suggested that the more critical analysis of translation manuals will benefit the on-going debates in the study of scientific behavior.     

Early stimulus processing in dysthymia and anhedonia.

Previous event-related brain potential (ERP) research has found that dysthymic subjects differ from control subjects during later stages of information processing. An important issue that emerges from this literature is whether differences found in these ERP components, typically associated with cognitive processing, can be attributed to earlier differences in basic perceptual processing. This study was undertaken to determine whether early processing deficits are apparent in dysthymic persons. Responses of dysthymics (n = 23) were compared with those of anhedonic (n = 15) and normal control (n = 17) subjects. ERPs were recorded while subjects heard tones at 55, 65, 75, 85, and 95 dB. Overall, N1-P1 and N1-P2 components of the ERP increased in a strong linear fashion as stimulus intensity increased. Dysthymics did exhibit a smaller N1-P2 response than normal subjects, which suggests the presence of difficulties in initial perceptual processing.     

Responding to a conditioned stimulus depends on the current associative status of other cues present during training of that specific stimulus.

The comparator hypothesis is a response rule stating that responding to a Pavlovian conditioned stimulus (CS) reflects the associative strength of the CS relative to that of other cues (comparator stimuli) that were present during CS training. Thus, modulation of the associative strength of a CS's comparator stimulus should alter responding to that CS. These studies examined the stimulus specificity of this effect using within-subjects designs. Rats were trained on 2 CSs, each with a unique comparator stimulus, to determine the degree to which posttraining extinction of the comparator stimulus for one CS influences responding to the other CS. Using negative contingency (Experiments 1 and 2), overshadowing (Experiment 3), and local context (Experiment 4) preparations, stimulus specificity was observed. In each case, posttraining extinction of the comparator stimulus for one CS had greater impact on responding to that CS than on responding to the alternate CS.     

Correlates of memory decline: a 4-year longitudinal study of older adults with memory complaints.

Change in memory performance and its correspondence to change in speed of performance and self-reported memory functioning were investigated longitudinally in 30 older adults with memory complaints. Subjects were assessed by self-report questionnaires and cognitive tests 3 times, at near 2-year intervals. A significant decline in word-recall scores was found, which was accompanied at the group level by significant self-reported decline in everyday memory functioning and nonsignificant decline in Wechsler Adult Intelligence Scale Digit Symbol scores (alpha = .05). The oldest subjects showed the most substantial declines in memory performance. At the individual level, however, memory change did not significantly correlate with either change in self-reports or change in Digit Symbol scores. Although these results do not support a cognitive slowing model of decline at the intraindividual level, they do have implications for intervention of age-related memory decline.     

Relations of socioeconomic status and sex variables to the complexity of worker functions in the occupational choices of elementary school children

The relationships of sex and socioeconomic status to complexity of worker functions in the occupational choices of elementary school children were studied. Complexity of worker functions was defined in terms of the most complex level of interaction required of a worker, when interacting with data, people, and things. The children included in the study were third- and fifth-grade students, divided on the basis of grade, sex, and socioeconomic status. The children's occupational choices were scored for complexity with the code numbers of the worker function hierarchies of the U.S. Employment Service's Dictionary of Occupational Titles (Washington, D.C.: U.S. Govt. Printing Office, 1977, 4th ed.). Findings based on the obtained data indicated the following: (a) a positive relationship between socioeconomic status and complexity of data manipulation in occupational choices; and (b) greater complexity of interaction with things in the occupational choices of boys, than girls. The positive relationship between socioeconomic status and complexity of data manipulation was accounted for by the children's exposure to their parents' orientation toward data manipulation. Apparent differences in the play activities of boys and girls was used to explain differences between the sexes in the levels of complexity of interactions with inanimate objects and animals.     

Salivation: an assessment of food craving?

The validity of salivation as a measure of hunger and food craving was examined. Previous studies examining the relationship between salivation, food cues, and self-reports of hunger and food craving reported inconsistent results. The present study, using a modification of the Strongin-Hinsie-Peck (SHP) test to measure salivation, examined these relationships with overweight subjects. Salivation measures were taken on 25 subjects in a weight-control program during three experimental conditions: baseline I, food exposure and baseline II. While food exposure significantly increased the amount of salivation as compared to baseline, salivation did not correlate with self-reports of hunger or food cravings. Significant correlations were found for salivation, age. sex, and body fat. Implications of these results are discussed.     

Coping In the Corporation: Sex Role Constraints

In this paper, the predictive power of status-based and socialization-based explanations of the differential rewards accruing to men and women in the corporate world are compared. Ninety-five experienced managers were asked to evaluate persuasive dialogues between two individuals in a corporate setting. Sex of the actor, sex of the other, and the influence technique used by the actor all affected the personality traits attributed to the influential actor. Our respondents perceived influential males as significantly more powerful, higher in corporate position, and warmer than identically described females. Implications of these and other findings for both male and female managers are discussed.     

Discrimination of auditory target dimensions in the presence or absence of variation in a second dimension by infants

Discrimination of two acoustic dimensions of auditory stimuli, vowel identity and pitch contour, was tested with infants between the ages of 4 and 16 weeks using the high-amplitude sucking (HAS) technique. Discrimination of the vowel dimension and the pitch dimension was tested under two conditions: when a change in the target dimension occurred in theabsence of constant variation in a second dimension, and when a change in the target dimension occurred in thepresence of constant variation in a second dimension. In addition, discrimination was tested in a combined condition in which one level of the vowel dimension was always combined with one level of the pitch dimension and the stimulus change to be detected was a recombination of the levels of each dimension. Sucking-recovery scores demonstrated that infants always discriminated a change in the target dimension when it occurred without variation in the second dimension, regardless of the dimension that served as the target. However, while variation of the pitch dimension did not alter vowel discrimination, variation in the vowel dimension interfered with discrimination of the pitch dimension. Discrimination was also not evidenced in the combined condition. Analysis of the group time-to-habituation (TH) data revealed that significantly longer TH scores were correlated with a failure to demonstrate discrimination. The data are discussed in terms of the formation of auditory perceptual categories in early infancy as they relate to the acquisition of speech and language and, more generally, to developmental attention and memory for auditory stimuli.
