Verbal problem-solving in agenesis of the corpus callosum: Analysis using semantic similarity.

Previous studies demonstrated that individuals with agenesis of the corpus callosum (AgCC) experience difficulties in novel and complex problem-solving. The present study investigated verbal problem-s... Capacity for semantic inference was tested in 25 individuals with AgCC and normal-range intelligence compared to 29 neurotypical controls. The Word Context Test (WCT) of Delis-Kaplan Executive Functio... With respect to the typical WCT scores, persons with AgCC had fewer total consecutive correct responses. In addition, semantic similarity to the correct word was significantly lower overall in persons... These findings indicated that individuals with AgCC who have intelligence in the normal range are less able at the WCT taking all trials into account, although they often solve the problem eventually....

The RESCUE problem solving intervention for stroke caregivers: A mixed-methods pilot study.

Stroke caregivers face many challenges after a family member experiences stroke. Because caregivers play such a crucial role in health care, there is a need for more interventions in web-based formats... A one-group, pretest-posttest design with a mixed-methods approach was used. Qualitative data supplemented the quantitative findings. Community-dwelling caregivers of stroke patients were recruited fr... Ninety-three caregivers were recruited; 72 caregivers completed the intervention and 21 withdrew (77% completion rate). From pre- to posttest, caregiver depression (... The intervention was feasible to implement and acceptable to caregivers. This intervention shows promise for fulfilling a need for more web-based interventions that focus on skills building and psycho...

Metacognitive prompts and numerical ordinality in solving word problems: An eye-tracking study.

The ability to translate concrete manipulatives into abstract mathematical formulas can aid in the solving of mathematical word problems among students, and metacognitive prompts play a significant ro... Based on the concept of semantic congruence, we explored the effects of metacognitive prompts and numerical ordinality on information searching and cognitive processing, throughout the process of solv... Participants included 73 primary school students (38 boys and 35 girls) with normal or corrected visual acuity.... This study was based on a 2 (prompt information: no-prompt, metacognitive-prompt) × 2 (number attribute: cardinal number, ordinal number) mixed experimental design. We analysed multiple eye-movement i... When solving both types of problems, pupil sizes were significantly smaller under the metacognitive-prompt condition compared with the no-prompt condition, and shorter dwell time for specific sentence... The results indicate that for Chinese upper-grade primary school students, cognitive load was lower in the metacognitive prompting condition and when solving cardinal problems, and higher when solving...

Social problem-solving attitudes and performance as a function of differences in trait and state worry.

This study investigated problem-solving attitudes and state-dependent, performance-based problem-solving abilities of individuals with high trait worry as compared to those low in trait worry. Seconda... A 2 (group: high worry, n = 68, vs. low worry, n = 66) X 2 (induction type: worry vs. neutral mentation) factorial design was employed to investigate the differential effects of state worry, and neutr... Previous findings that individuals with high trait worry endorse greater tendencies to self-report unconstructive problem-solving attitudes were replicated. Contrary to predictions, there were no sign... Study did not directly assess problem-solving for personal problems.... Disparities in self-appraisal may account for lack of worry-related performance differences. Findings suggest that when employing problem-solving interventions with a high worry population, emphasis s...
