An Introductory Lecture on Personality Assessment

The role of personality assessment is minimized in many introductory psychology presentations for a variety of reasons. Personality assessment is an area of great breadth and is understandably formidable to those whose training has been outside this area of specialization.

The following lecture was designed to digest at least some parts of the area of personality assessment in as non-technical language as possible for use of instructors introducing its basic concepts.     

Sensory substitution: an approach to the experimental study of perception / Sustitución sensorial: un abordaje para el estudio experimental de la percepción

Abstract

Sensory substitution refers to the phenomenon where object and environment information normally acquired through one sense can be obtained by another sense. For example, visual input being provided by hearing or touching. Sensory substitution devices are technological designs that transform the characteristics of one sensory modality into stimuli of another sensory modality. These devices were developed with two purposes: (1) to assist people with sensory disabilities in daily tasks; and (2) to study the involved mechanisms of brain plasticity. This article reviews studies in which sensory substitution phenomenon is employed as a methodological strategy to study visual perception. Furthermore, its use is discussed as an experimental platform to contrast new perceptual theories and underlying neurophysiological mechanisms that are currently under review.     

Factor structure of the construct of adaptive behavior in children with and without intellectual disability

Although the presence of significant limitations in adaptive behavior constitutes one of the three necessary criteria for diagnosing intellectual disability, adaptive behavior structure has always been the subject of considerable controversy among researchers. The main goal of this study is to extend previous research results that provide further support to a multidimensional structure of conceptual, social, and practical skills compared to the unidimensional structure. One-factor and 3-correlated factors models as measured by 15 observable indicators were analyzed by means of confirmatory factor analysis (CFA), as well as their relationships with one second-order factor (i.e., adaptive behavior). To that end, 388 children with and without intellectual disabilities were assessed with the Diagnostic Adaptive Behavior Scale (DABS). Results of CFA indicated that the 3 first-order factors solution provides the best fit to the data. Reliability and validity of the multidimensional model were also analyzed through different methods such as the composite reliability and the average variance extracted. Finally, implications of these findings and possible directions for future research are discussed.     

Psychological stress and blood glucose regulation in type I diabetic patients

Fifteen Type I diabetic patients self-monitored daily mean blood glucose levels (BGL), psychological stress, diet, exercise, and insulin injections for a period of 8 weeks. Separate multiple-regression analyses were conducted for each subject to assess the predictability of BGL from stress reports, independent of the effects of diet, exercise, and insulin self-administration. Considerable individual variability in findings was evident, with stress predicting BGL in a statistically significant manner in 7 of the 15 subjects. Stress had a significant effect on BGL independent of diet, exercise, and insulin administration for each of these 7 subjects. Discussion focused on the problems of measuring the key self-management behaviors influencing BGL and on the possibility that a subgroup of diabetic patients may be BGL stress responders.     

Conceptualising the relationship between shopper religiosity,perceived risk and the role of moral potency

The primary aim of this paper is to conceptualise the influence of shopper religiosity on perceived risk and the moderating role of moral potency when purchasing religiously questionable products from retailers. An extensive review of extant literature was undertaken, drawing together the General Theory of Marketing Ethics and the concept of moral potency, in a retail context. A conceptual model is developed that provide the basis for future inquiry. The model elucidates the complex relationships between the dimensions of religiosity and social and psychological risk and then explains the moderating role of moral potency. The model offers a strong psychological explanation of how a shoppers' religion may increase their perceptions of risk in a purchase situation. The model also argues that risk perceptions may be heightened (or lessened) as a result of the shoppers' personal responsibility, confidence and courage. Retail managers may choose to implement this model in order to better predict shopper adoption behaviour of new religiously questionable products. The model allows for future empirical examinations across multiple shopping contexts and may be employed to estimate levels' demand for new products based on the extent of religiosity, moral potency and risk. The role of religion within retailing and shopping behaviour is emergent. Extant retailing literature has previously overlooked the role of religion as an antecedent to risk and the role of moral potency in moderating that relationship. This is the first paper to highlight these gaps and propose a testable model. Copyright © 2016 John Wiley & Sons, Ltd.     

Predicting Women's Intentions to Leave Abusive Relationships: An Application of the Theory of Planned Behavior1

A theoretically derived decision‐making model was applied to predict women's intentions to remain in or to terminate physically abusive relationships with male partners. Participants were 48 women residing in a shelter for battered women who responded to questionnaires assessing the components of the theory of planned behavior. Data provided support for the model. Specifically, women were found to have greater intentions to leave the relationships if they held positive attitudes toward leaving and believed they were in control of leaving the relationship. Normative beliefs were not predictive of intentions to leave. Empirically based suggestions for increasing the effectiveness of interventions are discussed.     

Spatial learning of the water maze: Progression of brain circuits mapped with cytochrome oxidase histochemistry

The progression of brain circuits involved in spatial learning tasks is still a matter of debate. In addition, the participation of individual regions at different stages of spatial learning remains a controversial issue. In order to address these questions, we used quantitative cytochrome oxidase histochemistry as a metabolic brain mapping method applied to rats (Rattus norvegicus) trained in a water maze for 1, 3 or 5 days of training. Sustained changes throughout training were found in the lateral septal nucleus and anteroventral thalamic nucleus. As compared to naïve or habituation groups, rats with 1 day of training in the spatial learning task showed involvement of the lateral mammillary nucleus, basolateral amygdala and anterodorsal thalamic nucleus. By 5 days of training, there were mean changes in the hippocampal CA3 field and the prefrontal cortex. The regions involved and their pattern of network interactions changed progressively over days of training. At 1-day there was an open serial network of pairwise correlations. At 3-days there was a more closed reciprocal network of intercorrelations. At 5-days there were three separate parallel networks. In addition, brain-behavior correlations showed that CA1 and CA3 hippocampal fields together with the parietal cortex are related to the mastery of the spatial learning task. The present study extends previous findings on the progressive contribution of neural networks to spatial learning.     

"Holding on" or "coming to terms" with educational underachievement: a longitudinal study of ambition and attainment

Given mounting aspirations to graduate from college and pervasive difficulties in obtaining a four-year degree, growing numbers of young people in the United States have become "underachievers." Using data from the ongoing Youth Development Study, the authors examine the prevalence of "holding on" and "letting go" of high aspirations and the precursors of these states as youth move from high school through their mid-twenties. They find that advantage stemming from the family of origin and changing occupational circumstances engender persistence or reappraisal of earlier educational goals.
