Organizational Commitment,Job Satisfaction,and Effort in the Service Environment

Investigations of the causal relationship between organizational commitment and job satisfaction have yielded contradictory findings. Little empirical research has looked at this complex relationship in the context of work effort. The purpose of this study was to determine how these variables interact in the service environment. Using a sample of 425 employees in two service organizations, the author tested two structural equation models. The hypothesized model with organizational commitment as a moderator between job satisfaction and service effort fit better than a model with job satisfaction as moderator did. Conceptual implications are discussed, and suggestions for future research are made.     

Semantic Fluency Performance of Patients with Cortical and Subcortical Neurodegenerative Diseases

Previous studies using the Animals Fluency Test have shown that dementia patients with Alzheimer's disease (AD), Huntington's disease (HD), or Parkinson's disease (PD) produce fewer correct words and have smaller semantic cluster sizes than controls or PD patients without dementia (PDND). Although the number of correct words generated by the patients with AD was positively correlated with mental status, cluster size, surprisingly, was not. To increase word output and increase the reliability of estimates of cluster size, semantic fluency was reexamined using the Supermarket Fluency Task. Overall, patients with HD or PD with dementia (PDD) exhibited reduced cluster sizes compared to older controls or PDND patients, but cluster sizes were only marginally reduced for patients with AD. These effects were evident only for female participants, because the cluster sizes for elderly control men were substantially smaller than those of elderly women. For the female patients with AD, cluster size was correlated with mental status, but the relationship was nonlinear. Cluster size was normal for mildly demented patients with AD, but much reduced for moderately or severely demented participants. In contrast to a previous report, in the present study the proportion of category labels generated was increased for patients with HD with dementia but not for patients with AD. This finding questions one line of evidence that semantic memory stores undergo “bottom-up” degradation in AD. Together with previous results, these findings indicate that semantic cluster size reflects efficiency of access to semantic knowledge which is similarly compromised in subcortical and cortical diseases.     

Dewey’s Social Ontology: A Pragmatist Alternative to Searle’s Approach to Social Reality

Dewey’s social ontology could be characterized as a habit ontology, an ontology of habit qua second nature that offers us an account of intentionality, social statuses, institutions and norms in terms of habituations. Such an account offers us a promising alternative to contemporary intentionalist and deontic approaches to social ontology such as Searle’s. Furthermore, it could be the basis of a social ontology better suited to explain both the maintenance and the transformation of social reality.     

Appraisals,emotions and emotion regulation: An integrative approach

The present work aims to investigate the relation between appraisals, emotions, and emotion regulation strategies by creating a structural equation model which integrates these three aspects of the emotion process. To reach this aim, Italian students (N = 610) confronted with their high school diploma examination completed a questionnaire 3 weeks before the beginning of the exam. Results showed that they experienced primarily three types of emotions—anxiety/fear, frustration/powerlessness, positive emotions—which were related to specific appraisal profiles. Importantly, these appraisal profiles and emotions were associated with the use of different strategies for regulating emotions: anxiety/fear was associated with focusing on the exam, drug use, and an inability to distance oneself from the exam; frustration/powerlessness, with use of suppression, distancing, and drugs; positive emotion, with reappraisal and problem focused strategies. The effectiveness of these different strategies will be discussed.     

Unique Aspects of Adolescent Sexual Victimization Experiences

This study explored females' adolescent experiences with sexual aggression using event-level data. A community sample of women, ages 18 to 30 years ( N = 319), were interviewed regarding their most recent unwanted sexual experience. Incidents were categorized as occurring during adolescence (ages 14 to 17) or adulthood (after age 18). Preliminary statistical comparison of adolescent and adult incidents revealed differences in perpetrators, type of aggression, preceding activities, and location of assault. Qualitative analytic techniques were then used to identify the contexts in which adolescent victimization occurred, as well as the factors contributing to adolescent vulnerability. Four contexts in which adolescents were sexually victimized emerged: Within Intimate Relationships, At Parties/Social Gatherings, Abuse by Authority Figures, and While Alone With a Friend. Thematic analysis revealed that inexperience with sex and dating, lack of guardianship, substance use, social and relationship concerns, and powerlessness contributed to adolescent vulnerability within these contexts.     

Neurobiological Markers of Illness Onset in Psychosis and Schizophrenia: The Search for a Moving Target

In this review, we describe neuropsychological and brain imaging findings in the early stages of psychosis and schizophrenia. We focus on recent clinical high-risk studies and consider whether the evidence supports these as ‘endophenotypes’ of a vulnerability to the illness or as ‘biomarkers’ of illness onset and transition. The findings suggest that there are a number of processes at psychosis onset that may represent biomarkers of incipient illness. These neurobiological indices particularly implicate the integrity of frontal and temporal cortices, which may or may not be related to the genetics of psychosis (i.e. potential ‘endophenotypes’). However, these brain regions are dynamically changing during normal maturation, meaning that any putative neurobiological markers identified at the earliest stages of illness may be relatively unstable. We suggest that, while such measures may be readily identified as potential neurobiological markers of established illness, they are inconsistent at (or around) the time of illness onset when assessed cross-sectionally. Instead, identification of more valid risk markers may require longitudinal assessment to ascertain normal or abnormal trajectories of neurodevelopment. Accordingly, we assert that the current conceptualisations of potential biomarkers and/or ‘endophenotypes’ for schizophrenia may need to be reconsidered in the context of normal and abnormal brain maturational processes at the time of onset of psychotic disorders.     

Effects of similarity of location and temporal intensity pattern of conditioned and unconditioned stimuli on the acquisition of conditioned suppresion in rats.

This article two studies that examined the effect of similarity of location and temporal intensity patterns of the conditioned stimulus (CS) and the unconditioned stimulus (UCS) on the acquision of conditioned suppression. Experiment 1 showed that greater suppression occurs during a stimulus generalization test when the tested stimulus has a location and temporal intensity pattern that is similar to the previously presented UCS. Experiment 2 showed that conditioned suppression is acquired more rapidly if the CS and UCS have similar locations and temporal intensity patterns. These similarity factors were interpreted as forms of event covariation, which aided in associative formation. Several applications of these data are discussed.     

Common mechanisms of executive attention underlie executive function and effortful control in children

Executive Function (EF) and Effortful Control (EC) have traditionally been viewed as distinct constructs related to cognition and temperament during development. More recently, EF and EC have been implicated in top‐down self‐regulation ‐ the goal‐directed control of cognition, emotion, and behavior. We propose that executive attention, a limited‐capacity attentional resource subserving goal‐directed cognition and behavior, is the common cognitive mechanism underlying the self‐regulatory capacities captured by EF and EC. We addressed three related questions: (a) Do behavioral ratings of EF and EC represent the same self‐regulation construct? (b) Is this self‐regulation construct explained by a common executive attention factor as measured by performance on cognitive tasks? and (c) Does the executive attention factor explain additional variance in attention deficit hyperactivity disorder (ADHD) problems to behavioral ratings of self‐regulation? Measures of performance on complex span, general intelligence, and response inhibition tasks were obtained from 136 preadolescent children (M = 11 years, 10 months, SD = 8 months), along with self‐ and parent‐reported EC, and parent‐reported EF, and ADHD problems. Results from structural equation modeling demonstrated that behavioral ratings of EF and EC measured the same self‐regulation construct. Cognitive tasks measured a common executive attention factor that significantly explained 30% of the variance in behavioral ratings of self‐regulation. Executive attention failed to significantly explain additional variance in ADHD problems beyond that explained by behavioral ratings of self‐regulation. These findings raise questions about the utility of task‐based cognitive measures in research and clinical assessment of self‐regulation and psychopathology in developmental samples.
