On the interaction of the subject and the experiment in the matching model

Two types of matching designs, static and dynamic, are differentiated. While all matching designs are logically the same in terms of the probability model which determines chance level of performance, an attempt is made to demonstrate that there is an interaction between the tactics, strategies, and actual knowledge ofS and the type of design used which will, in turn, lead to different results even whenS's knowledge is held constant. It is suggested that analogous situations may exist within the framework of the traditional psychometric model.The work reported in this paper was supported by a National Science Foundation Undergraduate Research Participation Grant (NSF-G15797) to the senior author.

Depressive thoughts limit working memory capacity in dysphoria

Dysphoria is associated with persistence of attention on mood-congruent information. Longer time attending to mood-congruent information for dysphoric individuals (DIs) detracts from goal-relevant information processing and should reduce working memory (WM) capacity. Study 1 showed that DIs and non-DIs have similar WM capacities. Study 2 embedded depressive information into a WM task. Compared to non-DIs, DIs showed significantly reduced WM capacity for goal-relevant information in this task. Study 3 replicated results from Studies 1 and 2, and further showed that DIs had a significantly greater association between processing speed and recall on the depressively modified WM task compared to non-DIs. The presence of inter-task depressive information leads to DI-related decreased WM capacity. Results suggest dysphoria-related WM capacity deficits when depressive thoughts are present. WM capacity deficits in the presence of depressive thoughts are a plausible mechanism to explain day-to-day memory and concentration difficulties associated with depressed mood.     

What Does the Narcissistic Personality Inventory Measure Across the Total Score Continuum?

The Narcissistic Personality Inventory (NPI) is the most widely used measure of narcissism in the social-personality psychology literature. It contains 40 items that tap into a variety of traits that theoretically comprise narcissism, such as feelings of superiority and willingness to exploit others. Most researchers focus on the total score produced by the NPI and may logically assume that increments in total NPI score correspond with similar increments in underlying narcissism traits. However, research presented in this article suggests that the traits measured by the NPI do not increment at the same rate. Traits reflecting intrapersonally healthy qualities (e.g., leadership, superiority) increment most rapidly within the lower portions of the NPI total score continuum, whereas traits reflecting interpersonally harmful qualities (e.g., entitlement, exploitativeness) increment most rapidly within the upper portions of the NPI continuum. These differences have implications for the meaning of scores on the NPI and how they correlate with other variables. For example, we demonstrate that lower NPI scores best predict self-esteem and higher NPI scores best predict psychopathy.     

Staff and Boarders Perspectives of the Boarding Environment

This research provides support for a direct comparison between the home and boarding environments, the inference being that boarding staff who fulfil an in loco parentis role have an integral part to play in the developmental outcomes of adolescents (boarders). Research in the area of family functioning has found that adolescents tend to view the family environment more negatively than their parents and that these discrepant perceptions have been linked to both internalising and externalising disorders in adolescents. In an attempt to further clarify the influence of the parenting role of boarding staff and of the boarding environment in general, 121 staff and 415 boarders from schools in Queensland, Australia, were asked to rate the boarding environment on levels of conflict, social support and climate. It was found that boarders, like adolescents in the home environment, perceived significantly higher levels of conflict and lower levels of social support and positive climate than did staff. These findings lend further support to the conceptualisation of the boarding environment as a home away from home. The implications of these findings for boarders’ developmental outcomes are discussed.     

A contingent speech technique in eye movement research on reading

A novel eye-movement-contingent method is presented. It builds on and extends established eye-movement-contingent visual display change methods in that it uses movements of the eyes to control the presentation of acoustic information during sentence reading. In one implementation, an irrelevant spoken word is presented when the eyes cross a predetermined spatial boundary before they move on to a selected visual target word. The relationship between the spoken word and the visual target is manipulated, and the pattern of interference, caused by the presentation of the spoken word, is used to determine the nature and time course of activated representations. Results from three recently completed experiments in which the technique was used show that a word’s phonological code remains active after it has been read and that the activated code has speech-like properties.     

Changing Views of Serpent Handling: A Quasi-Experimental Study

Knowledge about serpent handling sects (SHS) even among social scientists and legislators has been largely influenced by biased media reports. Our own field research suggests that factual knowledge about SHS is effective in changing stereotypes about serpent handling and in altering views as to the rights of believers to handle serpents in church. In a quasi-experimental study, participants were pretested with respect to both prejudicial and reasoned evaluative views about SHS. Participants saw either a video of contemporary SHS in which handlers demonstrated and explained their faith, or a control tape in which contemporary SHS were shown but serpent handling was neither demonstrated nor defended. As predicted, viewing the serpent handling video was effective in reducing stereotyping of SHS and in changing attitudes regarding the sincerity of the believers and the right of SHS to practice their faith without legal constraints. Appropriate controls indicated that changes were not simply a function of a pretest by treatment interaction. The relevance of these data for altering laws against the practice of serpent handling is discussed.     

Bioethical issues in biostatistical consulting: development of a survey

To develop a survey, the Bioethical Issues in Biostatistical Consulting Questionnaire, for investigating bioethical issues in analysis, a comprehensive literature review was conducted to specify areas of bioethics. Through a focus group study and the evaluation by 10 biostatisticians, the questionnaire was constructed. Validation must involve a panel of experts. Now, test-retest reliability and factor analysis should be conducted on a group of eligible subjects.
