The frontal hypothesis of cognitive aging: factor structure and age effects on four frontal tests among healthy individuals

With 101 healthy aging adult participants, the authors investigated whether executive functions are a unitary concept. The authors established the factor structure of the Wisconsin Card Sorting Test (WCST; E. A. Berg, 1948), the Stroop color and word test (C. J. Golden, 1978), verbal fluency using the Controlled Oral Word Association Test (COWAT; Benton, 1967), and the Digits Backwards subtest of the Wechsler Adult Intelligence Scale-Revised (WAIS-R; D. Wechsler, 1981). The authors also evaluated the extent to which age and other demographic variables predicted common underlying properties of these frontal tests. Results revealed an age-related decline in executive abilities differentially reflected by the selected tasks. These data suggest caution using the COWAT to evaluate executive abilities in older people. The authors interpret findings to support the unitary view of executive abilities and the executive decline proposed by the frontal hypothesis.     

Relations of Parenting and Negative Life Events to Cognitive Diatheses for Depression in Children

In a sample of 299 children (grades 2, 4, and 6), we examined parenting and negative life events as predictors of depressive cognitions, specifically low self-perceived competence, depressive cognitive schemas, and depressogenic attributional style. We also examined developmental trends in these relations. Children completed measures of parenting, negative life events, and depressive cognitions. Parents also completed measures of parenting and negative life events. Consistent with our hypotheses, negative parenting and negative life events corresponded with higher levels of depressive cognitions, whereas positive parenting corresponded with lower levels of depressive cognitions. The relations between negative parenting and negative automatic thoughts were stronger for older children. Theoretical and practical implications are discussed.     

Building Bridges Across Differences to Meet Social Action Goals: Being and Creating Allies Among People of Color

Although challenges of anti-racist work are most commonly framed in relation to White people and People of Color, there are significant challenges involved in creating allies across minority racial groups. This article describes our experiences within a community organization aimed at training anti-racist culturally sensitive K-12 educators. As Asian American and Native American facilitators within a group of facilitators of color who were predominantly Black, we describe our experiences of relative marginalization and our (mostly failed) attempts to create change within the organization to be more inclusive of the perspectives, experiences, and needs of non-Black people/students of color. We contextualize these experienced conflicts in relation to race hierarchies, the “divide and conquer strategy” and the maintenance of White privilege. We offer reflections for how racial minorities engaged in anti-racist education could be better allies and how organizations might better foster environments that contribute to the creation of these alliances.

Education as an intergenerational process of human learning, teaching, and development

In this article I argue that the future of psychological research on educational processes would benefit from an interdisciplinary approach that enables psychologists to locate their objects of study within the cultural, social, and historical contexts of their research. To make this argument, I begin by examining anthropological accounts of the characteristics of education in small, face-to-face, preindustrial societies. I then turn to a sample of contemporary psychoeducational research that seeks to implement major, qualitative changes in modern educational practices by transforming them to have the properties of education in those self-same face-to-face societies. Next I examine the challenges faced by these modern approaches and briefly describe a multi-institutional, multidisciplinary system of education that responds to these challenges while offering a model for educating psychology students in a multigenerational system of activities with potential widespread benefits.     

Social inhibition of return

Responses to a target stimulus can be slower when it appears in the same rather than a different location to a previous event, an effect known as inhibition of return (IOR). Recently, it has been shown that when two people alternate responses to a target, one person’s responses are slower when they are directed to the same locations as their partner’s previous response. The present study sought to investigate this highly novel effect, which we term social IOR (SIOR), in relation to what is known of IOR in individuals performing alone. We found that only a real conspecific can induce SIOR in another person, whereas an animated conspecific cannot. Additionally, SIOR emerges at locations to which a conspecific has been inferred to respond, even when direct observation of his/her responses is prevented. Finally, SIOR can be induced without the abrupt visual transients normally associated with the generation of IOR. These findings suggest that SIOR is the result of stronger activations of IOR mechanisms, or that it is subserved by entirely separate inhibitory processes.     

Reciprocal relationships between value orientation and motivational interference during studying and leisure

Background. Motivational interference is defined as the amount of impairment in a target activity due to the incentives of a non‐chosen attractive alternative. The amount to which pupils experience motivational interference while studying or while performing a leisure activity in a school–leisure conflict situation is seen as depending on the values they attach to achievement and well‐being. At the same time, values may also be effects of frequent experience of motivational interference in the respective areas. Aims. The study is aimed at investigating the reciprocal relationship between personal value orientations and the experience of motivational interference during studying and leisure. Sample. A total of 363 pupils (sixth to eighth graders at the time of first measurement) completed the same questionnaire twice in a 2‐year interval. Method. The questionnaire included measures of achievement and well‐being value orientation and the experience of motivational interference during studying and during leisure in school–leisure conflicts. For this, two scenarios were created. In regression analyses, achievement and well‐being value orientations as well as their interaction terms were used as predictors for experience of motivational interference at t₂ while controlling for experience of motivational interference at t₁, and vice versa. Additionally in path models, these relations were tested in an integrative way. Results. Pupils' achievement value orientations were connected to differential changes in experiencing motivational interference during leisure and during studying in one scenario but only for pupils low or medium in well‐being value orientation. Conversely, experience of motivational interference at t₁ was related to changes in value orientations 2 years later. High motivational interference during studying led to an increase in well‐being value orientation, while high motivational interference during leisure was followed by a decrease in well‐being value orientation and an increase in achievement value orientation. Overall, path models supported these results. Conclusions. The results are discussed in terms of value change and are linked to self‐control and motivation research.     

Fractal Structure of Event Segmentation: Lessons From Reel and Real Events

We investigated fractality in the segmentation of cinematic and live events. Four movies from distinct genres were first analyzed and found to be fractal, albeit in different regions of the fractal range. In Experiment 1, viewers parsed the films' events, attending to short or long timescales, using a button box to indicate break points. The temporal structure of film viewing was found to be fractal regardless of the scale of attention and to reflect the differing fractal editing structure of the films. Experiment 2 found event segmentation to be fractal in a natural setting, a basketball game, as well. An additional parallel between reel and real events was uncovered: fractal indices were at the higher end of the range for both the film genre intended to be anxiogenic and the more suspenseful portion of the basketball game. We argue that the fractal structure of perception reflects the fractal structure of events whether the events are in film or in nature. We speculate that fractal structure has implications for understanding subjective experience and, ultimately, the correspondence between films and the world.     

Adaptation in Visuomanual Tracking Depends on Intact Proprioception

The role of arm proprioception in motor learning was investigated in experiments in which, by moving the arm, subjects followed the motion of a target displayed on a monitor screen. Adaptive capabilities were tested in visuomanual tracking tasks following alterations in the relationship between the observer's actual arm movement and visual feedback of the arm movement given by a cursor motion on the screen. Tracking performance and adaptive changes, measured in terms of spatiotemporal error, tracking trajectory curvature, and spatial gain, were compared in 7 control subjects (CSs) and in 1 deafferented subject (DS). CSs adapted appropriately to altered visuomanual relationships; those changes were present in trials immediately after restoration of normal scaling. In contrast, although the DS modified his tracking strategy from trial to trial according to the altered conditions, he did not show plastic changes in internal visuomanual scaling. Like the results of prismatic adaptation experiments, the present results suggest that arm proprioception contributes to the plastic changes that follow alterations in the scaling of visuomanual gain.     

Age and Cognitive Stress Influences Motor Skill Acquisition,Consolidation, and Dual-Task Effect in Humans

This study examined motor skill learning using a weight-bearing and cognitive-motor dual-task that incorporated unexpected perturbations and measurements of cognitive function. Forty young and 24 older adults performed a single-limb weight bearing task with novel speed, resistance, and cognitive dual task conditions to assess motor skill acquisition, retention and transfer. Subjects performed a cognitive dual task: summing letters in one color/orientation (simple) or two colors/orientations (complex). Increased cognitive load diminished the rate of skill acquisition, decreased transfer to new conditions, and increased error rate during an unexpected perturbation; however, young adults had a dual-task benefit from cognitive load. Executive function predicted 80% of the variability in dual-task performance. Although initial learning of a weight-bearing cognitive-motor dual-task was poor, longer term goals of improved dual-task effect and retention emerged.
