Prime time: Fatigue and set effects in the perception of reversible figures

Subjects viewed unambiguous versions of both stationary and rotating Necker cube illusions for varying durations prior to the presentation of the standard ambiguous figure. In each case, the subjects were more likely to report the ambiguous figure to be (1) in the same configuration as that of the preceding prime following brief preexposure periods and (2) in the opposite configuration from that of the preceding prime following long preexposure-periods. In addition, the number of reversals of the figure during the test period was also strongly related to the duration of the preexposure period, with progressively fewer reversals reported following longer preexposure periods. The results are interpreted as revealing the concurrent roles of “set” effects in the brief preexposure conditions and neural fatigue effects in the long preexposure conditions. Furthermore, the ability of the proposed two-process model to integrate the myriad of empirical effects in the reversible-figure literature is emphasized..     

Mental rotation of static and dynamic figures

Previous studies comparing performance on standard (i.e., static) and dynamic spatial test items have concluded that the two item types measure different abilities. Such conclusions about the uniqueness of static and dynamic spatial abilities seem premature, however, since only a limited number of dynamic spatial tasks have been utilized in research and these have differed markedly from their static counterparts. In the present studies, tasks were designed to require a common mental operation (mental rotation) under static and dynamic conditions. Correlations between static and dynamic performance ranged from .80 to .90. This appears to suggest that the emergence of a unique dynamic ability factor depends on the utilization of certain specialized tasks (e.g., arrival time tasks) with mental operations much different than those required by conventional spatial tests. In other words, it is apparently the requirement for different cognitive processes and not the processing of stimulus motion per se that distinguishes performance onsome dynamic tasks from performance on some standard static tasks.     

The Dimensions and Consequences of Organizational Politics Perceptions: A Confirmatory Analysis1

The present study, using confirmatory factor analysis, investigated the factorial structure of organizational politics perceptions. A second-order factor model was supported for both supervisor and subordinate samples. In addition, the hypothesis that different dimensions of perceived organizational politics lead to different satisfaction outcomes was also supported. Furthermore, it was demonstrated that subordinates reacted more negatively than did supervisors to politics perceptions. The results of the present study are discussed in light of directions for future research.     

Transient phonemic codes and immunity to proactive interference

Empirical data indicate that when memory for subspan lists of taxonomically related material is tested immediately after study, prior experience with lists involving the same material has no effect upon recall or recognition. In six experiments, we explored the possibility that immunity to proactive interference (PI) is related to discriminative information that is provided by transient phonemic codes. In these experiments, we manipulated the strength of phonemic codes as well as their presence or absence. Immunity to PI was found only when it was presumed that a phonemic representation of the target items existed and that information provided discriminative information. In all other cases, PI was observed. The finding that PI effects correspond with the manipulation of phonemic information in a principled fashion provides strong evidence for the role of phonemic codes in producing short-term PI effects.     

Ethical and legal issues in group counseling

Legal and ethical issues involved in group work are reviewed and discussed. Variations in different professional ethics codes are discussed. Recommendations for consideration by group leaders are made.     

The role of fundamental frequency in signaling linguistic stress and affect: Evidence for a dissociation

The fundamental frequency (F0) of the voice is used to convey information about both linguistic and affective distinctions. However, no research has directly investigated how these two types of distinctions are simultaneously encoded in speech production. This study provides evidence thatF0 prominences intended to convey linguistic or affective distinctions can be differentiated by their influence on the amount of final-syllableF0 rise used to signal a question. Specifically, a trading relation obtains when theF0 prominence is used to convey emphatic stress. That is, the amount of finalsyllableF0 rise decreases as theF0 prominence increases. When theF0 prominence is used to convey affect, no trading relation is observed.     

Race Differences on a Reading Comprehension Test With and Without Passages

Previous research has found that test takers can score above chance level on reading comprehension tests even when the passages are omitted. The present research investigated whether the effect would vary as a function of race. In Study 1, 386 participants completed a reading test with the passages omitted. General mental ability and race were significantly correlated with test performance. In Study 2, 827 job applicants completed the test as part of an entry-level selection battery. Eliminating items for which large race differences existed in Study 1 had no real effect on the size of the Black-White mean difference.     

THE MUTUAL ENRICHMENT OF BASIC AND APPLIED RESEARCH IN PSYCHOLOGICAL SCIENCE AND PRACTICE

Abstract— Dealing with the problems of substance abuse requires both an appreciation of clinical reality and an understanding of basic psychosocial principles. Each of the conference presentations of theory and research most of them nonapplied in nature, created a welcome and rare occasion for experimental and clinical psychologists (and hybrids) to reflect together on the applied implications of some basic research and on the research implications of some applied professional activities. Among the issues found especially noteworthy by this discussant. Here the following the return of cognition and rational decision making as legitimate and critical foci in behavior therapy, the role of exposure to aversive events in reducing their fearsomeness, the advantages of not working doggedly to achieve goals that are better approached with a nonachievement attitude the possibility that the difficulty in altering pathological behavior derives from the properties of human language, appreciation of individual differences in psychotherapy outcome research, the importance of considering the meaning that therapeutic ministrations can have for certain patients, and the need to reexamine the utility of patients expressing their concerns.
