Secondary control critiqued: is it secondary? is it control? Comment on Morling and Evered (2006)

In an insightful review on secondary control, B. Morling and S. Evered argued that the seminal article spawning the construct (F. Rothbaum, J. R. Weisz, & S. S. Snyder) contained the roots of two distinct conceptualizations focusing on "fit" and "control" and that distinguishing between them clarifies inconsistent research findings. They concluded that the best definition of secondary control focuses on fit. The author of the current commentary agrees with Morling and Evered's premises but draws the opposite conclusion. Herein, it is argued that (a) current control-focused definitions have more valid claims to the term secondary control, and (b) current incarnations that focus on "fit" are important, but they are not secondary and they are not control. Hence, fit-focused constructs should be liberated from the domain of control and studied in their own right, under their own more appropriate label, such as accommodative processes. Moreover, theoretical clarity and depth regarding the functions of fit-focused processes can be gained by examining these processes in relation to other underlying motives, such as belongingness or autonomy, to which they are more closely allied.     

Evaluating and Comparing Interventions Designed to Enhance Math Fact Accuracy and Fluency: Cover,Copy, and Compare Versus Taped Problems

An adapted alternating treatments design was used to evaluate and compare the effects of two procedures designed to enhance math fact accuracy and fluency in an elementary student with low cognitive functioning. Results showed that although the cover, copy, compare (CCC) and the taped problems (TP) procedures both increased the student's math fact accuracy and fluency, TP was more effective as it took less time to implement. Discussion focuses on the need to develop strategies and procedures that allow students to acquire basic computation skills in a manner that will facilitate, as opposed to hinder, subsequent levels of skill and concept development.     

An assessment of response, direction and place learning by rats in a water T-maze

Behavioral data suggest that distinguishable orientations may be necessary for place learning even when distal cues define different start points in the room and a unique goal location. We examined whether changes in orientation are also important in place learning and navigation in a water T-maze. In Experiment 1, rats were trained to locate a hidden platform and given a no-platform probe trial after 16 and 64 trials with the maze moved to a new position. Direction and response strategies were more prevalent than a place strategy. In Experiment 2, acquisition of place, response and direction strategies was assessed in a water T-maze that was moved between two locations during training. Rats were impaired on the place task when the maze was translated (moved to the L or R) but were successful when the maze was rotated across trials. These data are consistent with findings from appetitive tasks.     

Absolute Versus Tentative Interpretations: Mediating Effects of Client Locus of Control

An analog design was used to investigate the mediating effects of client locus of control (i.e., an internal focus or external focus) on perceptions of counselor style of interpreting events (i.e., absolute or tentative interpretations) on measures of perceived session depth and smoothness, and perceived counselor expertness, attractiveness, and trustworthiness. One hundred and thirty-four undergraduate college students, crossed on level of locus of control, were randomly assigned to one of two treatment conditions, and then completed measures of perceived session depth and smoothness, as well as perceived counselor expertness, attractiveness, and trustworthiness. Results indicated a significant interaction effect on perceived counselor trustworthiness. Implications for college counselors are provided.     

Stress and alcohol use: moderating effects of gender, coping, and alcohol expectancies.

A stressor vulnerability model of stress-induced drinking was tested in a stratified random sample of 1,316 Black and White adult drinkers. Stressors were highly predictive of both alcohol use and drinking problems among men who relied on avoidant forms of emotion coping or held strong positive expectancies for alcohol's effects and accounted for more than 35% of the variance in alcohol use among the subgroup of men who were high in both vulnerability factors. In contrast, stressors were negatively related among men who were low in both and were unrelated among women regardless of their coping or expectancies. These findings suggest that tension reduction theories of alcohol use are overly broad and that individual characteristics must be considered to account for stress-related effects on alcohol use and abuse.     

Application of chaos theory to biology and medicine.

The application of "chaos theory" to the physical and chemical sciences has resolved some long-standing problems, such as how to calculate a turbulent event in fluid dynamics or how to quantify the pathway of a molecule during Brownian motion. Biology and medicine also have unresolved problems, such as how to predict the occurrence of lethal arrhythmias or epileptic seizures. The quantification of a chaotic system, such as the nervous system, can occur by calculating the correlation dimension (D2) of a sample of the data that the system generates. For biological systems, the point correlation dimension (PD2) has an advantage in that it does not presume stationarity of the data, as the D2 algorithm must, and thus can track the transient non-stationarities that occur when the systems changes state. Such non-stationarities arise during normal functioning (e.g., during an event-related potential) or in pathology (e.g., in epilepsy or cardiac arrhythmogenesis). When stochastic analyses, such as the standard deviation or power spectrum, are performed on the same data they often have a reduced sensitivity and specificity compared to the dimensional measures. For example, a reduced standard deviation of heartbeat intervals can predict increased mortality in a group of cardiac subjects, each of which has a reduced standard deviation, but it cannot specify which individuals will or will not manifest lethal arrhythmogenesis; in contrast, the PD2 of the very same data can specify which patients will manifest sudden death. The explanation for the greater sensitivity and specificity of the dimensional measures is that they are deterministic, and thus are more accurate in quantifying the time-series. This accuracy appears to be significant in detecting pathology in biological systems, and thus the use of deterministic measures may lead to breakthroughs in the diagnosis and treatment of some medical disorders.
