Adults And Children

This investigation examined the response strategies and discrimination accuracy of adults and children aged 5–10 as the ratio of same to different trials was varied across three conditions of a “change/no-change” discrimination task. The conditions varied as follows: (a) a ratio of one-third same to two-thirds different trials (33% same), (b) an equal ratio of same to different trials (50% same), and (c) a ratio of two-thirds same to one-third different trials (67% same). Stimuli were synthetic consonant-vowel syllables that changed along a place of articulation dimension by formant frequency transition. Results showed that all subjects changed their response strategies depending on the ratio of same-to-different trials. The most lax response pattern was observed for the 50% same condition, and the most conservative pattern was observed for the 67% same condition. Adult response patterns were most conservative across condition. Differences in discrimination accuracy as measured by P(C) were found, with the largest difference in the 5- to 6-year-old group and the smallest change in the adult group. These findings suggest that children’s response strategies, like those of adults, can be manipulated by changing the ratio of same-to-different trials. Furthermore, interpretation of sensitivity measures must be referenced to task variables such as the ratio of same-to-different trials.

Methodological Considerations

In light of Lang’s differentiation of the aversive and the approach system – and assumptions stemming from attachment theory – this study investigates the role of the approach or caregiving system for processing infant emotional stimuli by comparing IAPS pictures, infant pictures, and videos. IAPS pictures, infant pictures, and infant videos of positive, neutral, or negative content were presented to 69 mothers, accompanied by randomized startle probes. The assessment of emotional responses included subjective ratings of valence and arousal, corrugator activity, the startle amplitude, and electrodermal activity. In line with Lang’s original conception, the typical startle response pattern was found for IAPS pictures, whereas no startle modulation was observed for infant pictures. Moreover, the startle amplitudes during negative video scenes depicting crying infants were reduced. The results are discussed with respect to several theoretical and methodological considerations, including Lang’s theory, emotion regulation, opponent process theory, and the parental caregiving system.

Psychological Inventory

Abstract. Many investigators have noted “reverse-coding” method factors when exploring response pattern structure with psychological inventory data. The current article probes for the existence of a confound in these investigations, whereby an item’s level of saturation with socially desirable content tends to covary with the item’s substantive scale keying. We first investigate its existence, demonstrating that 15 of 16 measures that have been previously implicated as exhibiting a reverse-scoring method effect can also be reasonably characterized as exhibiting a scoring key/social desirability confound. A second set of analyses targets the extent to which the confounding variable may confuse interpretation of factor analytic results and documents strong social desirability associations. The results suggest that assessment developers perhaps consider the social desirability scale value of indicators when constructing scale aggregates (and possibly scales when investigating inter-construct associations). Future investigations would ideally disentangle the confound via experimental manipulation.

Threat Evaluation

The Cognitive Shadow is a prototype tool intended to support decision making by autonomously modeling human operators’ response pattern and providing online notifications to the operators about the decision they are expected to make in new situations. Since the system can be configured either in a reactive “shadowing” or a proactive “recommendation” mode, this study aimed to determine its most effective mode in terms of human and model accuracy, workload, and trust. Subjects participated in an aircraft threat evaluation simulation without decision support or while using either mode of the Cognitive Shadow. Whereas the recommendation mode had no advantage over the control condition, the shadowing mode led to higher human and model accuracy. These benefits were maintained even when the tool was unexpectedly removed. Neither mode influenced workload, and the initial lower trust rating in the shadowing mode faded quickly, making it the best overall configuration for the cognitive assistant.

Recognizing a dose–response pattern based on heterogeneous tables of contrasts is hard. Specification of a statistical model that can consider the possible dose–response data-generating mechanism, including its variation across studies, is crucial for statistical inference. The aim of this article is to increase the understanding of mixed-effects dose–response models suitable for tables of correlated estimates. One can use the command drmeta with additive (mean difference) and multiplicative (odds ratios, hazard ratios) measures of association. The postestimation command drmeta_graph greatly facilitates the visualization of predicted average and study-specific dose–response relationships. I illustrate applications of the drmeta command with regression splines in experimental and observational data based on nonlinear and random-effects data-generation mechanisms that can be encountered in health-related sciences.

AbstractTo analyze functional and anatomical response patterns to dexamethasone (DEX) implant in diabetic macular edema (DME), to describe proportion of responders and non-responders, and to propose a new DME grading system. Retrospective, multicenter, observational cohort study. Naïve and non-naïve DME patients were treated with DEX, with visual acuity (VA) ≥ 0.2 logMAR and central subfield thickness (CST) of ≥ 300 µm. Functional and anatomical responses were graded after 2 and 4 months, and categorized as early and stable improvement, early and progressive improvement, pendular response, delayed improvement, and persistent non-response. 417 eyes were included (175 treatment naïve eyes). Compared to non-naïve eyes, naïve eyes showed a very good functional response (VA gain ≥ 10 letters) more frequently after 2 and 4 months (56% and 57% [naïve] vs. 33% and 28% [non-naïve], p < 0.001). A VA gain < 5 letters (non-response) after 2 and 4 months was seen in 18% and 16% of naïve eyes, and in 49% and 53% of non-naïve eyes (p < 0.001). A lack of anatomical response was rare in both groups, but more frequently in non-naïve eyes (12% vs. 4%, p = 0.003). Functionally and anatomically, naïve eyes showed most frequently an early and stable improvement (functionally: 77/175 44%; anatomically: 123/175 eyes, 70%). Most non-naïve eyes experienced no significant improvement functionally (97/242 eyes, 40%), despite a mostly early and stable improvement anatomical response pattern (102/242 eyes, 42%). Functional but not anatomical response patterns were influenced by baseline VA. Naïve and non-naïve eyes show different functional and anatomical response patterns to DEX implant. Functional non-responders are rare in naïve eyes, whereas anatomical non-response is unusual in both groups.

A 3×3×3 factorial design, N=135, is used to evaluate the effects of three conditions of feedback (zero, low extrinsic, and high extrinsic), three conditions of response pattern restriction (no restriction dictated, restriction to three patterns, restriction to one pattern), and three levels of repetitive-figure manipulation diversity determined by scores on Torrance Tests of Creative Thinking, Form A, Activity III: repetitive parallel lines. The experimental task was to turn nine circularly arranged knobs repetitively in a white visual, broadband audio environment over three 6-minute periods separated by rest pauses. O'Brien (1976) found significant differences for measures of response variability including pattern changing activity, pattern shifting, error factors, and other measures. An extended ad hoc analysis of that exploratory study is accomplished in which a comparison of percent common patterns emitted evidences that Ss who score differently on the pretest perform with different degrees of uniqueness when they are restricted to repetition of previous patterns, but not when they are free to vary types of patterns emitted. Also, comparison of initial trials indicates that high pretest scorers are more likely to begin the task with rarer patterns, low scorers use more common patterns, and intermediate scorers fall in between.
