The Nature and Time Course of Pragmatic Plausibility Effects

The experiments reported in this article used a delayed same/different sentence matching task with concurrent measurement of eye movements to investigate the nature of the plausibility effect. The results clearly show that plausibility effects are not due to low level lexical associative processes, but arise as a consequence of the processing of the earliest or most basic form of sentential meaning. In fact, when sentential implausibility and lexical association are varied simultaneously, it is only sentential implausibility that exerts an effect. Effects of implausibility occur rapidly—sometimes parafoveally—and are localised in the regions of the sentence where the implausibility occurs, suggesting an incremental interpretive process progressing on a roughly word-by-word basis. It is suggested that plausibility effects result from the operation of a heuristically-driven process of sentential interpretation. This appears to behave in a ‘modular’ fashion, despite being influenced by real world knowledge and probabilities.Particular thanks are due to Ken Forster for kindling the ideas which led to much of this work and to Merrill Garrett for posing impossible challenges, which, probably to everyone’s surprise, could in fact be met. I am also much indebted to Claire Boissiere, Emma Clayes, Clare Dobbin, Alan Kennedy, Julie-Ann Marshall, Ashley Murray, and Murray Rowan for their collaboration in this research.     

What's fine for the gander isn't always good for the goose: Sex differences in self-confidence as a function of ability area and comparison with others

Previous investigators have suggested that women display lower self-confidence than men across almost all achievement situations. The empirical validity of this suggestion is assessed in an experiment testing the following hypotheses: (1) Sex differences in self-confidence depend upon the particular ability area. (2) Women's self-confidence is more influenced than men's by characteristics of the particular individual with whom they compare themselves. Undergraduates completed verbal, interpersonal perceptiveness, spatial-mechanical, and creativity subtests. After each subtest, subjects estimated both their own score and that of the average undergraduate, the average male undergraduate, or the average female undergraduate. Self-confidence was operationally defined in terms of how favorably subjects compared their work to that of their peers. As predicted, women's self-confidence was lower than men's in only the spatial-mechanical and creativity subtests; and for women, but not for men, self-confidence depended upon which peer was specified. It is concluded that situation variables do determine sex differences in self-confidence and that women's self-confidence may be unduly affected by situation-specific comparison cues.The preparation of this article was supported in part by a Doctoral Dissertation Fellowship in Women's Studies awarded to the author by the Woodrow Wilson National Fellowship Foundation.

The interactive effects of conscientiousness and agreeableness on job performance

The authors hypothesized that the relationship between conscientiousness and job performance would be stronger for persons high in agreeableness than for those low in agreeableness. Results of hierarchical moderated regression analyses for 7 independent samples of employees across diverse occupations provided support for the hypothesis in 5 of the samples. In samples supporting the hypothesis, among the highly conscientious workers, those low in agreeableness were found to receive lower ratings of job performance than workers high in agreeableness. One explanation for lack of an interaction between conscientiousness and agreeableness in the other 2 samples is that those jobs were not characterized by frequent, cooperative interactions with others. Overall, the results show that highly conscientious workers who lack interpersonal sensitivity may be ineffective, particularly in jobs requiring cooperative interchange with others.     

When rejection stings: how self-esteem constrains relationship-enhancement processes

Three experiments examined how needs for acceptance might constrain low versus high self-esteem people's capacity to protect their relationships in the face of difficulties. The authors led participants to believe that their partner perceived a problem in their relationship. They then measured perceptions of the partner's acceptance, partner enhancement, and closeness. Low but not high self-esteem participants read too much into problems, seeing them as a sign that their partner's affections and commitment might be waning. They then derogated their partner and reduced closeness. Being less sensitive to rejection, however, high self-esteem participants affirmed their partner in the face of threat. Ironically, chronic needs for acceptance may result in low self-esteem people seeing signs of rejection where none exist, needlessly weakening attachments.     

Regularities of source recognition: ROC analysis

Source memory has become the focus of a growing number of investigations in a variety of fields. An appropriate model for source memory is, therefore, of increasing importance. A simple 2-dimensional signal-detection model of source recognition is presented. The receiver operating characteristics (ROCs) obtained from 3 experiments are then used to test the model. The data demonstrate 3 regularities: convex ROCs, z-ROCs with linear slopes of 1.00, and slightly concave z-ROCs. Two of these regularities support the model. The 3rd requires a revision of the model. This revised model is fitted to the data. The implications of these regularities for other theories are also discussed.     

Productive syntax abilities in Huntington's and Parkinson's diseases

This study examined syntactic changes in the spoken discourse of patients with Huntington's (HD) or Parkinson's disease (PD) and explored possible relationships between their syntactic changes and concomitant cognitive and motoric symptoms. Patient and control groups participated in a conversational discourse activity and completed a battery of standardized speech and cognitive tests. The HD group used shorter and fewer grammatically complete utterances than their healthy, age-matched peers, whereas there were no significant syntactic differences between PD patients and their healthy, age-matched peers or between PD and HD patients. Productive syntax abilities in HD and PD were meaningfully related to both neuropsychological and motor speech changes. These findings indicate that patients with subcortical disease, at least those with HD, may present with language production deficits and that these deficits are most likely the product of not only motor speech limitations (i.e., dysarthria) but also underlying cognitive impairments.     

Repetition blindness reveals differences between the representations of manipulable and nonmanipulable objects

We used repetition blindness to investigate the nature of the representations underlying identification of manipulable objects. Observers named objects presented in rapid serial visual presentation streams containing either manipulable or nonmanipulable objects. In half the streams, 1 object was repeated. Overall accuracy was lower when streams contained 2 different manipulable objects than when they contained only nonmanipulable objects or a single manipulable object. In addition, nonmanipulable objects induced repetition blindness, whereas manipulable objects were associated with a repetition advantage. These findings suggest that motor information plays a direct role in object identification. Manipulable objects are vulnerable to interference from other objects associated with conflicting motor programs, but they show better individuation of repeated objects associated with the same action.

Circumventing resistance: Using values to indirectly change attitudes

Most research on persuasion examines messages that directly address the attitude of interest. However, especially when message recipients are inclined to resist change, indirect methods might be more effective. Because values are rarely attacked and defended, value change could serve as a useful indirect route for attitude change. Attitudes toward affirmative action changed more when the value of equality was attacked (indirect change) than when affirmative action was directly attacked using the same message (Experiments 1-2). Changes in confidence in the value were responsible for the indirect change when the value was attacked (controlling for changes in favorability toward the value), whereas direct counterarguments to the message were responsible for the relative lack of change when the attitude was attacked directly (Experiment 2). Attacking the value of equality influenced attitudes toward policies related to the value but left policy attitudes unrelated to the value unchanged (Experiment 3). Finally, a manipulation of value confidence that left attitudes toward the value intact demonstrated similar confidence-based influences on policies related to the value of freedom (Experiment 4). Undermined value confidence also resulted in less confidence in the resulting policy attitudes controlling for the changes in the policy attitudes themselves (Experiments 3 and 4). Therefore, indirect change through value attacks presented a double threat-to both the policy attitudes and the confidence with which those policy attitudes were held (potentially leaving them open to additional influence).

Mechanisms by which parasites influence cultures, and why they matter

At least four conceptually distinct mechanisms may mediate relations between parasite-stress and cultural outcomes: genetic evolution, developmental plasticity, neurocognitive flexibility, and cultural transmission. These mechanisms may operate independently or in conjunction with one another. Rigorous research on specific mediating mechanisms is required to more completely articulate implications of parasite stress on human psychology and human culture.
