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.     

Response-monitoring dysfunction in schizophrenia: an event-related brain potential study

Error-monitoring abnormalities may underlie positive symptoms of schizophrenia. Response-synchronized event-related potentials during picture-word matching yielded error- and correct-response-related negativity (ERN, CRN) and positivity (Pe, Pc) and preresponse lateralized readiness potentials (LRP) from 18 schizophrenic patients and 18 controls. Both groups responded faster to matches than nonmatches, although patients were generally slower and made more errors to nonmatches. Compared with controls, patients, particularly with paranoid subtype, had smaller ERNs and larger CRNs, which were indistinguishable. LRPs showed evidence of more response conflict before errors than before correct responses in controls but not patients. Despite ERN/CRN abnormalities, post-error slowing and Pe were normal in patients, suggesting a dissociation of ERN and error awareness. Anterior cingulate and dorsolateral prefrontal cortical dysfunction in schizophrenia are implicated.     

Cognitions and behavior in asymmetric social dilemmas: a comparison of two cultures

This study investigated whether cognitions and behavior in an asymmetric social dilemma can be predicted by national culture. Results indicated that, as predicted, groups of decision makers from Japan--a collectivist, hierarchical culture-were more cooperative, expected others to be more cooperative, and were more likely to adopt an equal allocation distribution rule to resolve the dilemma than were groups of decision makers from the United States-an individualist, egalitarian culture. An opportunity for communication had a greater impact on expectations of others' behavior in groups of U.S. decision makers than in groups of Japanese decision makers.     

Spatial task performance,sex differences,and motion sickness susceptibility

There are substantial individual differences in susceptibility to motion sickness, yet little is known about what mediates these differences. Spatial ability and sex have been suggested as possible factors in this relationship. 89 participants (57 women) were administered a Motion Sickness Questionnaire that assesses motion sickness susceptibility, a Water-level Task that gauges sensitivity to gravitational upright, and a Mental Rotation Task that tests an individual's awareness of how objects typically move in space. Significant sex differences were observed in performance of both the Water-level Task (p<.01), and the Mental Rotation Task (p<.005), with women performing less accurately than men. Women also had significantly higher scores on the Motion Sickness Questionnaire (p<.005). Among men, but not women, significant negative relationships were observed between Water-level Task performance and Motion Sickness Questionnaire score (p<.001) and between Mental Rotation Task performance and Motion Sickness Questionnaire score (p<.005). In conclusion, women performed significantly more poorly than men did on the spatial ability tasks and reported significantly more bouts of motion sickness. In addition, men showed a significant negative relationship between spatial ability and motion sickness susceptibility.     

The Assessment of Individual Personality by Projective Tests: Current Problems

The Millon Clinical Multiaxial Inventory (MCMI) has been recently developed as an alternative to the Minnesota Multiphasic Personality Inventory (MMPI) and shares some of its psychometric advantages and disadvantages with the MMPI-168, a short form of the MMPI. The current study compared the structure and utility of the MCMI and MMPI-168 for a general hospital inpatient psychiatric population. Overall, the two instruments were highly correlated and found to have conceptually similar factor structures. Empirical comparison of the factor structures indicated that construct validity is greatest for neurotic traits. Both instruments demonstrated a similar utility in predicting discharge diagnosis.     

The Utility of the MAPI in the Assessment of Depression

The relationships between the Millon Adolescent Personality inventory (MAPI; Millon, Green, & Meagher, 1982) and depression, as assessed by the Multiscore Depression Inventory (MDI; Berndt, 1968) were examined. Elevations on the MDI subscales were positively related to elevations on MAPI personality style Scale 2 (Inhibited) and Scale 8 (Sensitive) and on six of the eight MAPI expressed concerns scales. MAPI personality style Scale 4 (Sociable) and Scale 5 (Confident) were negatively correlated with the MDI. MAPI code types containing either Scale 2 or 8 were associated with a high MDI full-scale score. The subjects who received a MAPI computer-generated diagnosis of borderline personality disorder also had elevated MDI full-scale scores. The findings of this study appear consistent with the existing body of MAPI research, and the data suggest that the MAPI personality style scales may have both state and trait qualities.     

The Hydraulic Principles Governing the Function of the Cochlea

General equation. Rejecting all fantastic “anatomical” data, that is, not making any anatomical assumptions but those of facts which are clearly visible under the microscope, but, on the other hand, taking conscientiously into account everything that can thus be seen, we derive a general equation describing the hydraulic functions of the mammalian cochlea.

Statement of the chief aim of the theory. Whenever anything occurs on the outside which deserves to be called a sound in the sense of the physicist, and which varies more or less periodically with the time, we want to know first, what length or lengths of the phragma will be involved, because this determines the number of sensitive cells stimulated and thereby the magnitude of the nervous flux (or “the sensation intensity,” loudness); and we want to know second, how frequently per time unit these various lengths of the phragma are shaken, because this determines the nature of the stimulation and accordingly the quality of the chemical process resulting in each of those sensitive cells (or “the sensation quality,” pitch). Thus, our most important aim must be the establishment of a relation between l and t.

Solution of the equation. The equation is solved in special cases for two-fold verificaton: (1) by auditory observation; (2) by experimentation on a large, transparent, hydraulic model.

Thirty years without adverse criticism. The hydraulic theory during its life of thirty years has received some praise by the few who were willing to read it, has been viciously misrepresented by some who would not or could not comprehend it, has been innumerable times dogmatically rejected by those who did not even know what it consists in. We invite serious criticism of its basic assumptions, its mathematical analysis and, last but not least, its agreement with the facts of hearing.

The concept of a “traveling” bulge is not a part of the hydraulic theory. The author requests textbook and magazine writers to cease misquoting him. He has never either enounced or supported any “traveling” bulge theory.     

Studies in the Principles of Judgments and Attitudes: I. Two Basic Principles of Judgment

The psychological test performance of 10 seven-year-old boys from an isolated, rural Guatemalan village was compared with ratings of their intelligence made by 42 adult village members. The adults' judgments were found to correlate strongly with the children's performance on the Embedded Figures, Verbal Analogies, and Memory-for-Designs Tests.
