Intact attentional control of working memory encoding in schizophrenia

This study reports evidence that individuals with schizophrenia (SC) demonstrate intact attentional selection for visual working memory (WM) storage. A group of 62 participants with SC and 55 control participants without SC were studied in a series of 5 experiments that examined the ability to use top-down and bottom-up cues to guide WM encoding, as well as the ability to spontaneously select a subset of representations for storage. Participants with SC exhibited a consistent and robust ability to use selective attention in the control of WM in all 5 experiments, demonstrating a remarkable island of preserved functioning given the broad spectrum of impairments of attention and WM that have been widely reported in those with SC. These findings indicate that attention is not globally impaired in SC and make it possible to delineate more precisely the nature of the specific impairment of attention in this disorder.     

Proximal antecedents and correlates of adopted error approach: a self-regulatory perspective

The current study aims to further investigate earlier established advantages of an error mastery approach over an error aversion approach. The two main purposes of the study relate to (1) self-regulatory traits (i.e., goal orientation and action-state orientation) that may predict which error approach (mastery or aversion) is adopted, and (2) proximal, psychological processes (i.e., self-focused attention and failure attribution) that relate to adopted error approach. In the current study participants' goal orientation and action-state orientation were assessed, after which they worked on an error-prone task. Results show that learning goal orientation related to error mastery, while state orientation related to error aversion. Under a mastery approach, error occurrence did not result in cognitive resources "wasted" on self-consciousness. Rather, attention went to internal-unstable, thus controllable, improvement oriented causes of error. Participants that had adopted an aversion approach, in contrast, experienced heightened self-consciousness and attributed failure to internal-stable or external causes. These results imply that when working on an error-prone task, people should be stimulated to take on a mastery rather than an aversion approach towards errors.     

Religiosity for Promotion of Behaviors Likely to Reduce New HIV Infections in Uganda: A Study Among Muslim Youth in Wakiso District

The study was done to determine the association between religiosity and behaviors likely to reduce new HIV infections among 1,224 Muslim youth. Respondents with Sujda, the hyperpigmented spot on the forehead due to prostration during prayers, were more likely to abstain from sex, be faithful in marriage, and avoid alcohol and narcotics. Males wearing a Muslim cap were more likely to abstain from sex and avoid alcohol and narcotics. Females wearing the long dress (Hijab) were also more likely to avoid alcohol. This data should be used by stakeholders in promoting behaviors likely to reduce new HIV infections among Muslims.     

Understanding and Assisting Couples Affected by an Eating Disorder

This article reviews the existing literature on heterosexual intimate relationships in which the female partner has an eating disorder. These couples often have trouble in a number of areas, including communication, sexual functioning, relational boundaries, and emotional health. Not only do these problems contribute to lower rates of relational satisfaction but they also affect a woman's chances for recovery. An understanding of this literature can inform family therapy practice. Recommendations are offered for those who provide counseling to these couples.     

Shape and Function in Hmong Classifier Choices

This study examined classifiers in the Hmong language with a particular focus on gaining insights into the underlying cognitive process of categorization. Forty-three Hmong speakers participated in three experiments. In the first experiment, designed to verify the previously postulated configurational (saliently one-dimensional, saliently two-dimensional, and saliently three-dimensional) characteristics of common Hmong classifiers, the participants were presented with pieces of wood in various shapes and were asked to select a classifier for each item. In the second experiment, designed to examine configurational and functional characteristics of two classifiers associated with saliently one-dimensional objects, the participants were asked to rate the acceptability of the two classifiers for different types of zippers. The interaction between the configurational and functional characteristics in the selection of a classifier was further examined in the third experiment, in which two target items—computer software and a computer processor—were respectively presented to the participants in three different manners with varying emphasis on their shapes and functions, and the participants rated the acceptability of different classifiers after each presentation. The results of these experiments indicate limitations of explaining common Hmong classifiers in terms of configurational characteristics and point to a need for greater attention to functional characteristics.     

The Changing Role of Fatherhood: The Father as a Provider of Selfobject Functions

Fatherhood is evolving. The way that men carry out their paternal role is reflective of the historical time era in which they live, social and cultural forces, both the mother and the father's expectations for fathering behaviors, as well as the father's own innate capabilities, wishes, and desires. Fatherhood is also greatly influenced by men's relationships with their own fathers, the quality of that relationship, and the extent to which the father was emotionally available. The ever-changing role of fathers has been a challenge for the psychoanalytic literature. There is no comprehensive theoretical body of knowledge about fatherhood that takes into account the changing nature of fathering, especially considering men's desires to be emotionally responsive and nurturing parents. This article examines the changing role of the father and suggests a model of paternal involvement that expands the nurturing and available father role to include the father as a selfobject. It discusses the importance of understanding men's relationships with their fathers, a central dynamic in shaping fathers’ involvement with their children. The residual impact of paternal deprivation is explored, followed by two clinical vignettes that symbolize the search for missing selfobject functions. This article concludes by outlining clinical implications and questions to pose to assess the selfobject relationship with one's father.     

Practice Effects on Motor Control in Healthy Seniors and Patients with Mild Cognitive Impairment and Alzheimer's Disease

ABSTRACT

This research was designed to test the hypothesis that motor practice can enhance the capabilities of motor control in healthy controls (NC) and patients with a diagnosis of probable Alzheimer's disease (AD) and mild cognitive impairment (MCI), and consequently results in better motor performance. Approximately half of the subjects in the NC (n = 31), AD (n = 28), and MCI (n = 29) either received or did not receive practice on a task of fast and accurate arm movement with a digitizer. Changes in movement time (MT), movement smoothness (jerk), and percentage of primary submovement (PPS) were recorded and compared among the three groups across six blocks of trials (baseline and five training sessions). For all subjects, practice improved motor functions as reflected by faster and smoother motor execution, as well as a greater proportion of programming control. Compared to unaffected matched controls, AD and MCI subjects exhibited a greater reduction in movement jerk due to practice. Movement time and PPS data revealed that motor practice appeared to reduce the use of “on-line” correction adopted by the AD or MCI patients while performing the aiming movements. Evidently, their arm movements were quicker, smoother, and temporally more consistent than their untrained peers. The findings of this study shed light on how MCI and AD may affect motor control mechanisms, and suggest possible therapeutic interventions aimed at improving motor functioning in these impaired individuals.     

Dependence on Visual Feedback During Motor Skill Learning in Alzheimer's Disease

Three experiments examined the role of visual feedback on the performance of a fine motor task, namely the rotary pursuit, in patients with Alzheimer's disease (AD) and healthy older adults. After extensive practice tracking a fully visible target, participants in Experiments 1 and 2 were tested under restricted vision (RV) conditions. In both experiments, the two groups showed a drop in performance when vision was restricted, with AD patients showing a significantly larger decline. Tracking improved significantly in normal controls, but not AD patients across the RV trials after the initial drop. When difficulty of the rotary pursuit task was manipulated in Experiment 3 without restricting vision, AD patients and normal controls showed identical patterns of performance. Consequently, it could be concluded that AD patients in the first two experiments were relying more heavily on visual information for accurate performance of the tracking task than their healthy peers.
