Interchurch Couples: The Issue of Acceptance

Although the literature suggests that couples who belong to two different churches or denominations (interchurch marriages) may face lack of acceptance, there is practically no research on this issue. Based on a recent qualitative study, this article explores the ways in which interchurch couples struggle to gain acceptance. Also discussed are the attitudes or factors that relate to level of acceptance, as well as the strategies that interchurch couples utilize to deal with lack of acceptance.     

A critique of the Flynn Effect: massive IQ gains, methodological artifacts, or both?

The Flynn Effect proposed by Flynn (1984; 1987) is reviewed and evaluated. Even in the presence of a skeptical and critical scrutiny of the effect, it appears that there is more than just methodological artifact to be explained. But the acceptance of the effect has been too quick. The proper explanations for the effect will not be meaningful until the nature of the effect is much better understood than it is now. Six questions are raised that have not been adequately answered. Two criticisms of the logic underlying the Flynn Effect are presented — one showing that even if IQ and SAT are highly correlated, their secular means will not necessarily track one another; the second showing that results by Flynn, (1984) are as consistent with a changing IQ variance as with a changing mean. The second of these is empirically evaluated with a re-analysis of a subset of the sources of Flynn's original 1984 data. Finally, 10 research strategies and designs are suggested that would help us better understand the effect. The critique is developed with the goal of clarifying the nature, meaning and causes of the Flynn Effect. The author hopes that this critique will stimulate both healthy skepticism about the Flynn Effect and careful research into its actual causes.     

Never cross the path of a traveling salesman: The neural network generation of Halstead-Reitan trail making tests

The Halstead-Reitan Trail Making Test (TMT) is one of the most widely used neuropsychological instruments for the assessment of brain damage. Despite its usefulness, however, the TMT has two major disadvantages. It has not been constructed in a principled manner that would facilitate systematic investigation, and there is no established procedure for generating equivalent, but stochastically different, test forms. The reason is that the generation of self-avoiding TMT pathways resembles the finding of near-optimal solutions to the Euclidean Traveling Salesman Problem (TSP) and constitutes a computational problem that is NP-complete. This article describes a practical approach to the problem of generating stochastically different test forms. This approach employs anelastic net neural network to generate TMT forms based on self-avoiding, near-optimal paths, and closed circuits. The usefulness and limitations of this solution are discussed briefly in relation to alternative and complementary problems and procedures.     

Child protection investigations: Discourse analysis and the management of incommensurability

This paper asks whether discourse analytic approaches in social psychology have yet produced methodologies adequate to the investigation of institutional ‘gaze’. Institutional language has been explored to the extent that state agencies construct members of the public by speaking about them in particular ways. This has often provided insight into the co-existence and competition of incommensurable discourses. However, studies of representation in the sense of speaking for have been notably absent from social psychology. It is argued that this aspect of discourse is a vital component in the study of contemporary governmental multi-agency strategy in the area of child protection, where recent legislation and policy aims at the coordination of incommensurable discourses. A methodology for studying this strategy is outlined through an account of the actor network approach in science studies, accounts of the State under the post-modern condition, and analyses of sections of interviews with social workers.     

Categorization response time with multidimensional stimuli

Categorization response time (RT) was examined in three separate experiments, in each of which exemplars varied on two physical dimensions. Three different types of stimuli were used: (1) horizontal and vertical line segments of varying length that were joined at an upper left corner, (2) rectangles of varying width and height, and (3) circles or semicircles of varying size with a radial arm of varying orientation. No evidence was found that stimulus familiarity or the category prototypes played any special role in determining categorization RT. Instead, RT decreased with distance from the stimulus to the categorization decision bound.     

Defensive behaviors in rats following septal and septal--amygdala lesions

Rats with anterior septal lesions showed a pattern of consistent enhancement of defensive behaviors normally elicited by threatening conspecifics, with no enhancement of attack or general reactivity. Further division of this group indicated that damage to sites anterior and ventral to the septal area, sites previously implicated in the "septal syndrome," produces maximal effect on these behaviors. When amygdala lesions are combined with septal damage this enhanced defensive responding is almost completely eliminated. These results were interpreted as indicating that the septal syndrome represents hyperdefensiveness to conspecific threat stimuli rather than aggression or increased general reactivity, and that amygdaloid mechanisms are also involved in the regulation of conspecific defensive behaviors.     

ESTABLISHMENT OF NONDELUSIONAL RESPONSES IN A SOCIALLY WITHDRAWN CHRONIC SCHIZOPHRENIC1

Multiple treatment interventions including instructions, modelling, timeout, avoidance of repetition, and reinforcement were successful in establishing factual answers to personal background questions in a withdrawn and socially unresponsive chronic schizophrenic. The subject had previously persisted in giving only delusional responses to these questions. A multiple-baseline design across verbal replies to personal background questions demonstrated that the changes in behavior were brought about by the treatment interventions. During baseline, the subject was reinforced for any response to four questions. The experimental interventions were then introduced for the first question and moved sequentially to an additional question when the subject's responses reached the criterion of at least 80% correct for two consecutive sessions. Introduction of the experimental interventions produced an increase from a baseline level of zero to at least 80% correct for each question. The use of the token reinforcement procedure was faded out after the subject was able to answer all four questions correctly at least 80% of the time for two consecutive sessions. Fading of the token reinforcement procedure was accomplished by using increasingly intermittent schedules of token reinforcement during the last seven sessions. In the final session, no tokens were used to reinforce the subject's responding. Nine-, ten-, and 12-month followup interviews were conducted to evaluate the maintenance of treatment gains. Maintenance was found to be complete at the nine- and 10-month followups, but at the 12-month followup interview, the subject answered one question incorrectly. This study replicates an investigation previously reported in this journal.     

Field independence and performance on ball-handling tasks

Subjects were administered the Children's Embedded Figures Test and four ball-handling tests. Pearson product-moment correlations were low between the measures. Girls scored significantly higher than boys on the embedded figures test while boys scored significantly higher than girls on the striking and throwing tests.     

Prepositional phrases spoken and heard

The relation between verbal and nonverbal behavior with common syntactic properties was investigated, using retarded and nonretarded children. Reinforcement was contingent on either verbal or nonverbal responses whereas responses of the other repertoire had no experimental consequences. Changes sometimes occurred in the unreinforced (collateral) repertoire, but they were always changes in the stimulus control of pre-existing topographies. A contingency involving responses of one repertoire never instated new topographies in the collateral repertoire. This suggested that the problem of “cross-modality generalization” should be reformulated to distinguish explicitly between instating new topographies and changing the stimulus control of pre-existing topographies. The result confirmed Skinner's hypothesis about “the same response spoken and heard” and clarified some anomalies in previous studies.
