Contextual influences on implicit evaluation: a test of additive versus contrastive effects of evaluative context stimuli in affective priming

Drawing on two alternative accounts of the affective priming effect (spreading activation vs. response interference), the present research investigated the underlying processes of how evaluative context stimuli influence implicit evaluations in the affective priming task. Employing two sequentially presented prime stimuli (rather than a single prime), two experiments showed that affective priming effects elicited by a given prime stimulus were more pronounced when this stimulus was preceded by a context prime of the opposite valence than when it was preceded by a context prime of the same valence. This effect consistently emerged for pictures (Experiment 1) and words (Experiment 2) as prime stimuli. These results suggest that the impact of evaluative context stimuli on implicit evaluations is mediated by contrast effects in the attention to evaluative information rather than by additive effects in the activation of evaluative information in associative memory.     

Culture,ethnicity, and mental health

Conclusion This is the important point, I think, both in the research field and in the research-policy-administrative-political field that might be characterized by the collective interests of people in these fields. Our discussions do not suggest unalterable directions for our efforts, and whatever answers we may come up with do not suggest final conclusions. If we are able to trust one another and our institutions-and I feel that trust is one of the key issues in any discussion about mental-health topics—then we have to admit that perhaps we are all correct. And our progress in the area of ethnicity, culture, and mental health will be promoted by our continued co-operation.the National Institute of Mental Health, Department of Health, Education, and Welfare.This paper is the substance of an address given at the Conference on Culture and Ethnicity-Mental Health Services for a Pluralistic Society held under the sponsorship of the Institute on Pluralism and Group Identity, American Jewish Committee of New York, and the Maurice Falk Medical Fund of Pittsburgh, at the University of Pittsburgh School of Medicine, Department of Psychiatry, on October 13, 1976.     

The self-regulation of automatic associations and behavioral impulses

The distinction between automatic processes and controlled processes is a central organizational theme across areas of psychology. However, this dichotomy conceals important differences among qualitatively different processes that independently contribute to ongoing behavior. The Quadruple process model is a multinomial model that provides quantitative estimates of 4 distinct processes in a single task: the likelihood that an automatic response tendency is activated; the likelihood that a contextually appropriate response can be determined; the likelihood that automatic response tendencies are overcome when necessary; and the likelihood that in the absence of other information, behavior is driven by a general response bias. The model integrates dual-process models from many domains of inquiry and offers a generalized, more nuanced framework of impulse regulation across these domains. The model offers insights into many central questions surrounding the operation and the interaction of automatic and controlled processes. Applications of the model to empirical and theoretical concerns in a variety of areas of psychology are discussed.     

Electrical stimulation of human hair follicles via microelectrodes

Trains of electrical pulses were applied to hair follicles on the forearm by microelectrodes with tip diameters less than 5 μ. Clear, painless, vibratory sensations could be evoked by stimulating the middle of a follicle. Exponents of the individual power functions relating vibratory magnitude and electric current ranged from 3.1 to 7.4. Absolute thresholds varied little with pulse frequency but did vary from S to S and from one electrode placement to another. Pitch discrimination was very poor; Ss could not distinguish 40 from 80 pps. Pain was often present, but the manner of its appearance suggested an anatomical segregation between vibratory and pain receptors.     

Rhetorical theory and family therapy practice

The study found that a connection exists between rhetoric and therapy because both fields are interested in using language as a tool for generating change. Persuasion is viewed as inherent in human communication, even though people do not necessarily intentionally attempt to persuade others. Following a brief (but detailed) explanation of the theoretical stance which informs the implementation of rhetorical techniques in therapy, three pragmatic exemplars are offered to demonstrate the employment of two classical rhetorical concepts, the parastasis catalogue and syncrisis.The authors are grateful to Sandra Kodner, MS for her participation in the development of this project.     

What Do Implicit Measures Tell Us? Scrutinizing the Validity of Three Common Assumptions

ABSTRACT— Experimental paradigms designed to assess "implicit" representations are currently very popular in many areas of psychology. The present article addresses the validity of three widespread assumptions in research using these paradigms: that (a) implicit measures reflect unconscious or introspectively inaccessible representations; (b) the major difference between implicit measures and self-reports is that implicit measures are resistant or less susceptible to social desirability; and (c) implicit measures reflect highly stable, older representations that have their roots in long-term socialization experiences. Drawing on a review of the available evidence, we conclude that the validity of all three assumptions is equivocal and that theoretical interpretations should be adjusted accordingly. We discuss an alternative conceptualization that distinguishes between activation and validation processes.     

A meta-analysis on the correlation between the implicit association test and explicit self-report measures

Theoretically, low correlations between implicit and explicit measures can be due to (a) motivational biases in explicit self reports, (b) lack of introspective access to implicitly assessed representations, (c) factors influencing the retrieval of information from memory, (d) method-related characteristics of the two measures, or (e) complete independence of the underlying constructs. The present study addressed these questions from a meta-analytic perspective, investigating the correlation between the Implicit Association Test (IAT) and explicit self-report measures. Based on a sample of 126 studies, the mean effect size was .24, with approximately half of the variability across correlations attributable to moderator variables. Correlations systematically increased as a function of (a) increasing spontaneity of self-reports and (b) increasing conceptual correspondence between measures. These results suggest that implicit and explicit measures are generally related but that higher order inferences and lack of conceptual correspondence can reduce the influence of automatic associations on explicit self-reports.     

The effect of Parkinson's disease on the control of multi-segmental coordination

An experiment was designed to test whether or not Parkinson's disease (PD) patients were able to maintain endpoint kinematic patterns in a prehension task involving movement of the torso. Nine PD patients and nine healthy controls were asked to reach for and grasp a full cup of water that was either covered or uncovered and placed beyond the reach of the outstretched arm. An OPTOTRAK (Northern Digital) 3-dimensional motion analysis system was used to capture the movement of four markers placed on the arm, hand, and torso. The results indicated the Parkinson's patients had a decreased ability to maintain the kinematics of the end effector. The PD patients were also found to be impaired in terms of their ability to synchronize the arm, hand, and torso. More specifically, although the elderly controls seemed to employ a strategy of increasing the involvement of the torso when reaching to grasp the uncovered cup, no such strategy was observed in the PD patients. Collectively, the results suggest that the multi-joint synergies observed in the elderly controls, which help preserve relatively consistent endpoint trajectories, are disrupted in Parkinson's patients.
