Influence of Connectives on Language Comprehension: Eye tracking Evidence for Incremental Interpretation

An eye-tracking experiment investigated whether incremental interpretation applies to interclausal relationships. According to Millis and Just's (1994) delayed-integration hypothesis, interclausal relationships are not computed until the end of the second clause, because the processor needs to have two full propositions before integration can occur. We investigated the processing of causal and diagnostic sentences (Sweetser, 1990; Tversky & Kahneman, 1982) that contained the connective because . Previous research (Traxler, Sanford, Aked, & Moxey, 1997) has demonstrated that readers have greater difficulty processing diagnostic sentences than causal sentences. Our results indicated that difficulty processing diagnostic sentences occurred well before the end of the second clause. Thus comprehenders appear to compute interclausal relationships incrementally.     

Cardiovascular reactivity to psychological stress in aerobically trained versus untrained mild hypertensives and normotensives

Cardiovascular reactivity to video game and mental arithmetic stressors was compared among three groups of men: aerobically trained mild hypertensives, untrained mild hypertensives, and a comparison group of untrained normotensives. Relative to the untrained hypertensives, the trained hypertensives reacted to the video game with marginally smaller systolic blood pressure and diastolic blood pressure, but there were no significant differences between these groups in reactivity during the mental arithmetic task. Comparisons between each hypertensive group and the normotensive group showed that blood pressure (BP) reactivity of normotensives during the video game was generally similar to that of trained hypertensives but smaller than that of untrained hypertensives. These results indicate that aerobic training, which has been found to reduce resting BP in mild hypertensives, may also exert a favorable impact in reducing cardiovascular reactivity of hypertensives during some stressful situations.     

BEHAVIORAL MOMENTUM IN THE TREATMENT OF NONCOMPLIANCE

Behavioral momentum refers to the tendency for behavior to persist following a change in environmental conditions. The greater the rate of reinforcement, the greater the behavioral momentum. The intervention for noncompliance consisted of issuing a sequence of commands with which the subject was very likely to comply (i.e., high-probability commands) immediately prior to issuing a low-probability command. In each of five experiments, the high-probability command sequence resulted in a “momentum” of compliant responding that persisted when a low-probability request was issued. Results showed the antecedent high-probability command sequence increased compliance and decreased compliance latency and task duration. “Momentum-like” effects were shown to be distinct from experimenter attention and to depend on the contiguity between the high-probability command sequence and the low-probability command.     

UNIVERSALISM IN LAY CONCEPTIONS OF DISTRIBUTIVE JUSTICE: A CROSS-CULTURAL EXAMINATION

In two studies of Japanese and Australian university students, we examined the resource allocation rules of equity and equality. In both cultures, subjects were universalistic rather than relativistic in their judgments of fairness and alterability of these rules in the work place. They judged the equity rule to be unalterable by legislation or consensus. However, in both studies, the Japanese perceived equity to be less fair and equality to be less unfair than their Australian counterparts. In addition, study 2 indicated that cross-cultural differences in judgments of fairness were influenced by consideration of need. The age of the worker was a more important determinant of fairness judgments for Japanese than for Australians; the debt of a worker was a more important déterminant for Australians than for Japanese. The results are discussed with regard to the role of culture in conceptions of distributive justice.     

Hindsight bias: An interaction of automatic and motivational factors?

If subjects are asked to recollect a former response after having been informed about the correct response, their recollection tends to approach the correct response. This effect has been termedhindsight bias. We studied hindsight bias in an experiment requiring numerical responses to almanac-type questions for physical quantities. We varied (1) the time at which the correct information was provided, (2) the encoding of the original responses by asking/not asking subjects to give a reason for the respective response, and (3) the motivation to recall correctly. We found that hindsight is less biased if reasons are given and if the correct information is provided at an earlier time. Motivation had only interactive effects: (1) With high motivation to recall correctly, the time the correct information was provided had no influence. (2) With reasons given, the variation of motivation showed no effect. These results rule out purely motivational and purely automatic explanations.     

Type A behavior and emotional responses to uncertainty: A test of the self-appraisal model

The self-appraisal model of Type A behavior holds that Type A's desire an accurate appraisal of abilities, and respond to uncertainty about abilities with exaggerated attempts to generate diagnostic information. The model also predicts that the major emotional response to uncertainty for Type A's is anxiety. In this study, Type A's and B's were induced to succeed or fail on a task where they were either very certain or very uncertain of their subsequent ability levels. Task failure produced greater depression, anger, and frustration for all subjects. Consistent with the self-appraisal model's prediction, uncertainty (regardless of success or failure) led to greater anxiety for Type A's than for Type B's. In fact, greater uncertainty produced lower anxiety for Type B's, indicating that Type A's and B's differ dramatically in their emotional responses to uncertainty about abilities.
