Development of infant reaching behaviors: Kinematic changes in touching and hitting

This longitudinal study investigated the development of reaching in typical infants, from age 4 to 8 months, and described the pattern of hand kinematics underlying changes in the characteristics of infants’ actions while reaching for a target. Thirteen infants were followed biweekly. Two reaching behaviors emerged during the infants’ free interactions with the target, touching and hitting. Changes over time were documented for the number of movement units, straightness index, distance, peak velocity and time to peak velocity of the hand for touches and hits. We observed increases in the numbers of touches and hits and changes in hand kinematics over time; the distance traveled by the hand was greater for hitting compared to touching. These kinematic changes were specific to the movement patterns that infants adopted to reach to the target.     

Dimensionality of the Rosenberg Self-Esteem Scale and Its Relationships With the Three-and the Five-Factor Personality Models

The interpersonal correlates of the Guilt Inventory (Kugler &; Jones, 1992), which yields scores for state guilt, trait guilt, and moral standards, were assessed. Data collection addressed three issues including the relationships among Guilt Inventory scores and measures of: (a) interpersonal emotions and traits (e.g., shyness, self-consciousness, anger, etc.); (b) the social support network; and (c) ratings of trait guilt, moral standards, and relevant adjectives by friends and family members. Results indicated that trait and state guilt scores were significantly related to various interpersonal measures, most particularly, depression, anxiety, shyness, and loneliness, but only modestly related to satisfaction with social support. Moral standards were generally unrelated to these variables. Others tended to rate participants higher on trait guilt negatively (e.g., higher on contemptuous, angry, guilty, etc.), and participants higher on moral standards in socially acceptable terms (e.g., higher on prompt, self-reliant, moral, and religious). Results are interpreted in view of the frequently cited distinction between social and nonsocial emotions.     

Zuckerman's Revised Alternative Five-Factor Model: Validation of the Zuckerman-Kuhlman-Aluja Personality Questionnaire in Four French-Speaking Countries

The aim of this study was to analyze the replicability of Zuckerman's revised Alternative Five-factor model in a French-speaking context by validating the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA–PQ) simultaneously in 4 French-speaking countries. The total sample was made up of 1,497 subjects from Belgium, Canada, France, and Switzerland. The internal consistencies for all countries were generally similar to those found for the normative U.S. and Spanish samples. A factor analysis confirmed that the normative structure replicated well and was stable within this French-speaking context. Moreover, multigroup confirmatory factor analyses have shown that the ZKA–PQ reaches scalar invariance across these 4 countries. Mean scores were slightly different for women and men, with women scoring higher on Neuroticism but lower on Sensation Seeking. Globally, mean score differences across countries were small. Overall, the ZKA–PQ seems an interesting alternative to assess both lower and higher order personality traits for applied or research purposes.     

Say one for me: the implicit religion of prayers from the street

Within the field of the psychology of prayer, there has been a growing interest in empirical studies concerned with the analysis of the content of ordinary people's private prayers, with a view to providing a more nuanced understanding of the psychological correlates of prayer among those who engage in the activity. One research tradition has focused on the content analysis of intercessory prayer requests left in church-related settings, and it is within this context that the present study is located, examining 417 intercessory prayer requests, collected on the streets by bishops in the Church of England as part of the 2011 “Say One for Me” Lent Prayer initiative. The study was informed by the constructs of implicit religion and ordinary theology, and employed ap Siôn's general analytical framework for intercessory prayer requests. Three types of implicit religion were found to be present in the prayer content: societal consensus, the source of explicit religion, and the effect of explicit religion, and the significance of these results is discussed.     

Subjectivity,health and gender: an approach to chronified pain through the Psychosocial Gender Diagnostic methodology / Subjetividad,salud y género: una aproximación al dolor cronificado mediante la metodología del Diagnóstico Psicosocial de Género

Abstract

This paper bases itself on a psychological perspective to make a theoretical and methodological proposal that shifts the concept of health towards the crossing point between biomedical and social sciences. To that end, it is suggested that the concept of Subjectivity should be placed at the centre of the discipline of psychology, understanding it from the theoretical perspective that intersects between post-structuralism, psycho-dynamic theory and gender. The objective of the article is to make this proposal through a case study about chronic pain without organic cause, an emerging, contemporary, controversial malaise that is becoming increasingly common, called Fibromyalgia in the biopsychomedical field, and which affects mainly — but not only — women. In order to pursue this goal, a new methodological instrument was developed: the psychosocial gender diagnostic, oriented toward capturing the dynamics of chronic pain. This methodology facilitates the integration of the connections between subjectivity, gender and health, while at the same time problematizes the excessive medicalization of modern day life.     

A first step toward cognitive remediation of voices: a case study

Several studies have shown that source-monitoring errors are related to verbal hallucinations in schizophrenia. An exploratory pilot study has been carried out to investigate the possibility of training patients in how to avoid errors in source-monitoring. One patient with paranoid schizophrenia and persistent thought insertions was trained for 6 hours to use mnemonic techniques to compensate specific deficits in source-monitoring. Results show that the patient was able to improve his performance and maintain the acquired progress at a 1-month follow-up assessment. These preliminary results are interesting for developing a larger controlled study of cognitive remediation of source-monitoring deficits.     

Is severe obesity a form of addiction? Rationale, clinical approach, and controlled clinical trial.

For many, obesity is just a problem of energy input and expenditure: more energy input than expenditure. However, the clinical practice and epidemiological data clearly show that weight control is more complex than expected by this simple equation. This is particularly true in morbid obesity, a form of severe obesity in which a person's Body Mass Index (BMI, kg/m(2)) is over 40. If we compare the definitions and diagnostic criteria for "dependence" and "addiction" with the situation of many severe obese subjects, it is apparent that they match very well. Further, different neurological studies confirm this similarity: both addiction and obesity patients have a deficiency of dopamine receptors. Nevertheless, when we compare many of the actual obesity treatments with the ones used in the area of addictions it is possible to find relevant differences: obesity treatments neither consider different levels of type and intensity of care, nor a multidimensional approach. To overcome these limitations, in this paper we propose a bio-psychosocial approach in which the genetic influence (lack of dopamine receptors) is matched by psychosocial issues (pressure for thinness and diet as main body image dissatisfaction treatment). Further, the paper outlines how this approach may influence the treatment options, by focusing both on the lessons coming from actual addiction treatment and the opportunities offered by virtual reality. Finally, the paper presents and discusses the outcome of a controlled trial, based on the proposed approach, including a 6-month follow-up (211 morbid obese females with a BMI of >40 and a documented history of failures.     

Conscious, preconscious, and subliminal processing: a testable taxonomy

Of the many brain events evoked by a visual stimulus, which are specifically associated with conscious perception, and which merely reflect non-conscious processing? Several recent neuroimaging studies have contrasted conscious and non-conscious visual processing, but their results appear inconsistent. Some support a correlation of conscious perception with early occipital events, others with late parieto-frontal activity. Here we attempt to make sense of these dissenting results. On the basis of the global neuronal workspace hypothesis, we propose a taxonomy that distinguishes between vigilance and access to conscious report, as well as between subliminal, preconscious and conscious processing. We suggest that these distinctions map onto different neural mechanisms, and that conscious perception is systematically associated with surges of parieto-frontal activity causing top-down amplification.     

Aiming at a far target under different viewing conditions: visual control in basketball jump shooting

Most research on visual search in aiming at far targets assumes preprogrammed motor control implying that relevant visual information is detected prior to the final shooting or throwing movements. Eye movement data indirectly support this claim for stationary tasks. Using the basketball jump shot as experimental task we investigated whether in dynamic tasks in which the target can be seen until ball release, continuous, instead of preprogrammed, motor control is possible. We tested this with the temporal occlusion paradigm: 10 expert shooters took shots under four viewing conditions, namely, no vision, full vision, early vision (vision occluded during the final +/-350 ms before ball release), and late vision (vision occluded until these final +/-350 ms). Late-vision shooting appeared to be as good as shooting with full vision while early-vision performance was severely impaired. The results imply that the final shooting movements were controlled by continuous detection and use of visual information until ball release. The data further suggest that visual and movement control of aiming at a far target develop in close correspondence with the style of execution.     

Blinded by trust in close others: Examining the effect of social closeness on cooperative behaviors during the COVID-19 pandemic

In the context of public health crises such as the COVID-19 pandemic, it is essential that individuals cooperate by complying with preventive measures (e.g., wearing a mask). The current research examines how high trust in close others is linked to less cooperation—that is, less compliance with measures—and thus, undermines collective interests. Specifically, we test whether individuals are less willing to comply with preventive measures when interacting with close others they trust. We conducted two experiments in which participants read a vignette depicting a social interaction with either close others (e.g., family) or strangers. Participants had to report the extent to which they would (1) trust the other people in the situation and (2) comply with the mask wearing and physical distancing measures during this interaction. In both experiments, we find that when individuals are considering an interaction with close others, they report experiencing higher trust which is then linked to lower compliance with preventive measures. In Experiment 2, we further demonstrate that participants report less compliance with preventive measures around close others, even when they perceive non-compliance with the measures as morally “wrong”. Our findings shed light on the challenges that compliance with preventive measures poses during social interactions in a context of high trust.
