Can contesting orientations predict grittier,more self-controlled athletes?

Grit and self-control are highly desired qualities of character in the sport arena. This two-study investigation used a new theoretical approach, contesting theory, to examine whether contesting orientations could predict these characteristics among intercollegiate athletes. Contesting theory identifies two distinct modes of cognitively processing the meaning and purpose of contesting, one rooted in a contest-is-partnership metaphor and the other a contest-is-war metaphor. Study 1 (N = 799) found that contesting orientations added incremental utility beyond demographic and control variables to the prediction of the two dimensions of grit (perseverance and consistency). Specifically, the partnership orientation positively predicted higher grit scores. Study 2 (N = 1179) replicated the findings of Study 1 with only minor variations and also demonstrated that contesting orientations add to the prediction of self-control. Results are discussed in terms of the practical implications for sport practitioners and, more broadly, the value of contesting theory to positive psychology.     

A mind to go out of: reflections on primary and secondary consciousness

Dreaming and waking are two brain-mind states, which are characterized by shared and differentiated properties at the levels of brain and consciousness. As part of our effort to capitalize on a comparison of these two states we have applied Edelman's distinction between primary and secondary consciousness, which we link to dreaming and waking respectively. In this paper we examine the implications of this contrastive analysis for theories of mental illness. We conclude that while dreaming is an almost perfect model of organic psychosis, it is less so for schizophrenia and major affective disorder where it must serve a primarily heuristic role helping us to model hallucinations and delusions but not the diseases themselves.     

Duration discrimination of brief light flashes

The data from four experiments indicate that when Os discriminate between light flashes of different durations, for durations for which Bloch’s law has been shown to hold, their discriminations are frequently made on the temporal information available in the flashes rather than on their apparent brightness. A model for duration discrimination which specifies that discriminability depends only on the difference in duration between the two brief flashes, and is independent of their durations, is presented and applied to the data.     

Developmental change and the multidimensional cognitive system

The cognitive system is a multidimensional, hierarchically-structured arrangement of cognitive dimensions functionally organized into three subsystems: perceiving, conceptualizing, and symbolizing. Ontogenetic change in these subsystems is described using theoretical concepts from both multivariate developmental psychology and systems theory. Both quantitative and qualitative changes in cognitive dimensions are discussed, including a synthesis of relevant empirical research. The Gompertz equation is used to describe the general form of quantitative change throughout the life-span. The pattern oo quantitative development involves growth, stability, and decline. The pattern of qualitative development, or shifts in structural organization, also invloves three periods: divergence, parallelism, and paraller-convergence. Thus, the overall quantitative-qualitative synthesis reveals a three-phase sequence of cognitive development: divergent growth (childhood- adolescence), parallel stability (adulthood), and parallel-convergent decline (old age).     

Influences of cognitive complexity on the dimensions underlying perceptions of the work environment

The literature on cognitive processes suggests that individuals differ in the dimensions they use to describe the work environment and thus the behavioral implications they attach to characteristics of that environment. Using the technique described by Bem and Allen (1974), navy enlisted personnel were separated into subgroups with high, medium, and low cognitive complexity scores. Responses about perceived characteristics of the work environment produced six components for the high complexity group versus four for the low group. Questions about supervisor behaviors, role characteristics, and work group interactions yielded similar dimensions for all groups, although differences were found for responses about macroorganizational characteristics. Significant but low relationships were found between complexity scores and global indices of job performance.This article is Report Number 79-2, supported by Naval Medical Research and Development Command, Department of the Navy, under Research Work Unit MF58.524.022-0011.

Perceiving surfaces in depth beyond the fusion limit of their elements

An isolated dot appears double outside a small disparity range called Panum's fusional area. In random-dot stereograms (RDSs), however, this doubling, or diplopia of dot elements is not evident at any disparity. Nevertheless, depth is perceived up to disparities that greatly exceed Panum's fusional limit. Either one is unaware of dot diplopia at disparities exceeding Panum's fusional limit or the fusion limit is extended. To examine these possibilities, we developed a novel RDS in which dichoptically color-coded dots have a distinctive color when fused, and return to their intrinsic colors when diplopic. We measured the fusion limit of dots in this RDS, and compared it to the patent stereopsis limit of the perceived surface in similar RDSs. We found that the fusional area of dots in the RDS was comparable to Panum's fusional area. Furthermore, there was clear dissociation between the fusion limit and the patent stereopsis limit in the RDS. We conclude that the elements composing a surface are not necessarily fused when a large disparity surface is perceived in depth.     

Language and modeling word problems in mathematics among bilinguals

The study was conducted to determine whether the language of math word problems would affect how Filipino-English bilingual problem solvers would model the structure of these word problems. Modeling the problem structure was studied using the problem-completion paradigm, which involves presenting problems without the question. The paradigm assumes that problem solvers can infer the appropriate question of a word problem if they correctly grasp its problem structure. Arithmetic word problems in Filipino and English were given to bilingual students, some of whom had Filipino as a first language and others who had English as a first language. The problem-completion data and solution data showed similar results. The language of the problem had no effect on problem-structure modeling. The results were discussed in relation to a more circumscribed view about the role of language in word problem solving among bilinguals. In particular, the results of the present study showed that linguistic factors do not affect the more mathematically abstract components of word problem solving, although they may affect the other components such as those related to reading comprehension and understanding.
