Measuring secondhand smoke exposure in babies: the reliability and validity of mother reports in a sample of low-income families.

The reliability and validity of mother's reports of their infants' exposure to secondhand smoke (SHS) were examined in an ethnically diverse sample of low-income, low-education families (N = 141 mothers). At baseline and posttest, smoking mothers reported about their infants' SHS exposure at different locations and by different sources during the previous week. Findings show that mothers can give reliable accounts of the degree to which they contribute to their babies' SHS exposure. Mothers are able to differentiate between their own smoking behavior and the extent to which they expose their infants. Consistent with the overall exposure pattern, exposure caused by the mother and exposure occurring at home showed the strongest associations with biological and environmental measures. These findings suggest that smoking mothers can provide reliable and valid reports of the degree to which their infants are exposed to SHS.     

The effect of contingency upon the appetitive conditioning of free-operant behavior

The problem of maintaining independence between response rates and reinforcement probabilities when determining the effect of varying the response-reinforcement contingency upon free-operant behavior was solved by programming local reinforcement probabilities for response and no response on a second-by-second basis. Fifty-seven rats were trained to lever-press on schedules of water reinforcement involving different values of contingency. All rats were first trained on a high positive contingency and then shifted to less positive, zero, or negative contingencies. Under these conditions, rate of lever-pressing declined appropriately when the contingency between response and reinforcement decreased or was made negative. The decline in rate produced by a zero contingency cannot be attributed to extinction, since the probability of reinforcement given the occurrence of a response was the same as for the positive contingency from which the shift to zero was made. That is, there was no change in the opportunity for response-reinforcement contiguity. It was concluded that the technique of programming local reinforcement probabilities offers promise for more critical examinations of the effects of contingency upon free-operant behavior.     

Evidence for abstract response codes: Ear-hand correspondence effects in a three-choice reaction-time task

A three-choice reaction-time task was used to investigate the source-of-stimulation effect, that is, the tendency for subjects to react faster and more accurately to a stimulus if the spatial locations of the stimulus and the response correspond than if they do not. Auditory stimuli varied on dimensions of tonal frequency and spatial location, although only the former was relevant for response selection. Responses were found to be faster for the conditions in which stimulus location and response location corresponded than for those in which they did not, but stimulus location had no effect on differences between the two hands with bimanual responses. These results support the hypothesis that the source-of-stimulation effect is due to response plans which interact at a level prior to the programming of the motor response.     

Hemispheric differences in temporal resolution

A review of the relevant clinical and experimental literature gives the conclusion that the cerebral hemispheres differ in temporal resolution of input, with the language-dominant hemisphere showing finer acuity. This conclusion is supported by evidence from performance of patients with unilateral brain damage on tests of temporal resolution, performance of developmental dyslexics on similar tasks, and left-right sensory field differences in temporal acuity in normal human subjects. While it is unlikely that a hemispheric difference in temporal resolution is sufficient to give a complete account of lateralized functions, such attempts to show more primitive physiological differences between the hemispheres are more likely to be fruitful than attempts which differentiate the hemispheres in terms of higher-order psychological functions.

Interpretation revealed in the blink of an eye: depressive bias in the resolution of ambiguity

Self-report measures of interpretation have been criticized on methodological grounds. An approach is introduced in this article that enables the assessment of interpretive bias with a greater degree of methodological rigor than previously has been the case. Psychophysiological researchers have established that the magnitude of the human blink reflex is augmented when elicited during negative rather than neutral imagery. The 1st experiment demonstrates that the blink reflex is sensitive to the emotional valence of imagery evoked by interpretations imposed on ambiguous stimuli. In the 2nd experiment, this measure is used to assess interpretations imposed on ambiguous stimuli by individuals who differ in depression levels. The findings are consistent with the hypothesis that depression is associated with a negative interpretive bias.     

A collaborative effort to study mother—child interaction in three risk groups: Social risk mother,adolescent mother,preterm infant

This paper describes the collaborative efforts of three intervention projects with similar data sets on high-risk populations of mothers and their children at 13 and 20 months. The three projects collected data on a total of 190 dyads from three risk groups: adolescent mothers and their infants, high social risk mothers and their infants, and high social risk mothers and their preterm infants. The authors define the common set of measures and resulting variables used collaboratively to measure parent-child interaction and compare the three risk groups at both 13 and 20 months.     

The influence of desire for control on drivers' risk-taking behaviour

Increases in perceived control over the driving task are known to increase intended driving speeds. Also, some people like being in control more than others. In the present study, we compared drivers with a high desire for control and drivers with a low desire for control, as measured on Burger and Cooper's (1979) [Motivation and Emotion 3 (4) (1979) 381] Desirability of Control Scale. Using validated video simulation techniques, we found that drivers with a high desire for control intended to drive at faster speeds and were willing to pull out into smaller gaps in traffic. We discuss the results in terms of an illusion of control and we describe implications for road safety interventions.
