The Relationship between Everyday Problem Solving and Inconsistency in Reaction Time in Older Adults

ABSTRACT

The purpose of the present study was to investigate whether inconsistency in reaction time (RT) is predictive of older adults' ability to solve everyday problems. A sample of 304 community dwelling non-demented older adults, ranging in age from 62 to 92, completed a measure of everyday problem solving, the Everyday Problems Test (EPT). Inconsistency in latencies across trials was assessed on four RT tasks. Performance on the EPT was found to vary according to age and cognitive status. Both mean latencies and inconsistency were significantly associated with EPT performance, such that slower and more inconsistent RTs were associated with poorer everyday problem solving abilities. Even after accounting for age, education, and mean level of performance, inconsistency in reaction time continued to account for a significant proportion of the variance in EPT scores. These findings suggest that indicators of inconsistency in RT may be of functional relevance.     

Adolescent mental health: the role of youth and college pastors

The present study investigates the gatekeeping role of youth and college pastors, specifically exploring their psychological training, perceptions, attitudes, and interactions concerning adolescent congregants' mental illness. Texas youth and college pastors were anonymously surveyed regarding referral patterns, mental health interventions and contact, adolescent mental health perceptions, and means of collaboration. While the sample reported actively working with numerous adolescent mental health issues, the majority did not feel qualified to work with significant psychopathology. Despite this, they reported using various intervention methods, with the most common being initial counselling followed by a referral. Although the sample frequently referred to other professionals, they described many perceived barriers in collaborating with others in the mental health field. Overall, a positive role exists for youth and college pastors in adolescent mental health; however, tensions and conflicts between pastors and mental health professionals hinder the usefulness of these unique gatekeepers. Implications and recommendations for mental health professionals are highlighted.     

What is wrong with the world

In 'Subjunctive Conditionals: Two Parameters vs. Three' Pavel Tichy articulates and defends a three-parameter account of counterfactuals. In the paper, he responds to a well known objection against the validity of various forms of inference, in particular strengthening of the antecedent, contraposition, and hypothetical syllogism. In this paper, I argue that his response to the objection is inadequate. I then propose an alternative form of the three-parameter account of counterfactuals that avoids the objection in question.     

Incarnation and the Divine Hiddenness Debate

This paper examines the debate that has arisen in connection with J. L. Schellenberg's work on divine hiddenness. It singles out as especially deserving of attention Paul Moser's proposal that the debate distinguish more clearly between classical theism and Hebraic theisms. This worthwhile proposal, I argue, will be unlikely to exert its full potential influence upon the debate unless certain features of Christian incarnation belief are recognized and addressed in connection with it.     

Malevolent Creativity in Terrorist Organizations

Terrorist organizations are both imitative and innovative in character. While the drivers of imitation have been extensively modeled using concepts such as contagion and diffusion, creativity and innovation remain relatively underdeveloped ideas in the context of terrorist behavior. This article seeks to redress this deficiency by presenting a conceptual framework with which we can understand the complex nature and multiple drivers of creativity and innovation within terrorist organizations. The overriding questions we address are: what factors spark creativity and innovation within terrorist organizations, and are there particular organizational traits that increase an organization's propensity to be creative and innovative? Using insights from industrial and organizational psychology and aided by illustrative examples and case studies from the history of terrorism, we aim to show that the multiple drivers of creativity and innovation are identifiable. By providing a conceptual framework that explores these key issues, we suggest that a much clearer research agenda for these issues may emerge. We conclude with a discussion concerning how our framework can help inform counter‐terrorism practices.     

Tremor Frequencies

In an attempt to improve logical reasoning performances, 64 introductory psychology students were randomly assigned to experimental and control groups. The experimental condition involved solving logic syllogisms when the obvious “logical error” was not included as a possible answer. Control subjects solved the same problems with the “logical error” included as a choice. An analysis of variance procedure applied to the subjects' logic pretest-posttest gain scores indicated that the experimental group did significantly better than the control group on invalid principles. The results were discussed in terms of Piaget's theory of logical thinking and the possibility of performance rather than competence problems in adult reasoning. The need to develop more effective instructional techniques to enhance transfer of learning was underscored.     

Is the emotional Stroop task a special case of mood induction? Evidence from sustained effects of attention under emotion

Sustained effects of emotion are well known in everyday experience. Surprisingly, such effects are seldom recorded in laboratory studies of the emotional Stroop task, in which participants name the color of emotion and neutral words. Color performance is more sluggish with emotion words than with neutral words, the emotional Stroop effect (ESE). The ESE is not sensitive to the order in which the two groups of words are presented, so the effect of exposure to emotion words does not extend to disrupting performance in a subsequent block with neutral words. We attribute this absence of a sustained effect to habituation engendered by excessive repetition of the experimental stimuli. In a series of four experiments, we showed that sustained effects do occur when habituation is removed, and we also showed that the massive exposure to negative stimuli within the ESE paradigm induces a commensurately negative mood. A novel perspective is offered, in which the ESE is considered a special case of mood induction.     

Structured contexts and anaphoric dependencies

Sensitivity to the extra-linguistic context, as exhibited by indexical and demonstrative expressions, and sensitivity to the linguistic context, as exhibited by, for example, anaphoric uses of third person pronouns, are regularly regarded as different and independent phenomena. The data on indexicals, demonstratives, and third person pronouns, however, call for a more unified notion of context and of context sensitivity. This paper aims to develop such a unified picture by generalizing the notion of anaphora to encompass extra-linguistic context dependency and generalizing the notion of a structured discourse context so that contexts contain antecedents for expressions that refer to entities in the extra-linguistic context.     

Parental Emotion Socialization in Clinically Depressed Adolescents: Enhancing and Dampening Positive Affect

This study compared parental socialization of adolescent positive affect in families of depressed and healthy adolescents. Participants were 107 adolescents (42 boys) aged 14 – 18 years and their parents. Half of the participants met criteria for major depressive disorder and the others were demographically matched adolescents without emotional or behavioral disorders. Results based on multi-source questionnaire and interview data indicated that mothers and fathers of depressed adolescents were less accepting of adolescents’ positive affect and more likely to use strategies that dampen adolescents’ positive affect than were parents of healthy adolescents. Additionally, fathers of depressed adolescents exhibited fewer responses likely to enhance the adolescents’ positive affect than were fathers of healthy adolescents. These findings build on those of previous work in examining parental responses to adolescent emotions, focusing on positive emotions and including both mothers and fathers.     

Prospective memory: Effects of divided attention on spontaneous retrieval

We examined the effects of divided attention on the spontaneous retrieval of a prospective memory intention. Participants performed an ongoing lexical decision task with an embedded prospective memory demand, and also performed a divided-attention task during some segments of lexical decision trials. In all experiments, monitoring was highly discouraged, and we observed no evidence that participants engaged monitoring processes. In Experiment 1, performing a moderately demanding divided-attention task (a digit detection task) did not affect prospective memory performance. In Experiment 2, performing a more challenging divided-attention task (random number generation) impaired prospective memory. Experiment 3 showed that this impairment was eliminated when the prospective memory cue was perceptually salient. Taken together, the results indicate that spontaneous retrieval is not automatic and that challenging divided-attention tasks interfere with spontaneous retrieval and not with the execution of a retrieved intention.
