The Joint Multivariate Modeling of Multiple Mixed Response Sources: Relating Student Performances with Feedback Behavior

The present study concerns a Dutch computer-based assessment, which includes an assessment process about information literacy and a feedback process for students. The assessment is concerned with the measurement of skills in information literacy and the feedback process with item-based support to improve student learning. To analyze students’ feedback behavior (i.e. feedback use and attention time), test performance, and speed of working, a multivariate hierarchical latent variable model is proposed. The model can handle multivariate mixed responses from multiple sources related to different processes and comprehends multiple measurement components for responses and response times. A flexible within-subject latent variable structure is defined to explore multiple individual latent characteristics related to students’ test performance and feedback behavior. Main results of the computer-based assessment showed that feedback-information pages were less visited by well-performing students when they relate to easy items. Students’ attention paid to feedback was positively related to working speed but not to the propensity to use feedback.     

The Patient-Staff Community Meeting: A Tea Party with the Mad Hatter

The author shows how object relations group therapy focuses on primitive defense mechanisms that shape the group-entity image or “basic assumptions group.” Such primitive defense mechanisms as splitting, projective identification, omnipotent denial, projection, and introjection are the mental resources to protect the endangered self and the threatened objects from the fantasized imminent destruction. Object relations group psychotherapy addresses those defenses and the underlying psychotic anxieties, offering members opportunities to search for other ways to respond to their primitive fears. The author introduces two extensive clinical vignettes to illustrate how object relations group methods are different from other group-centered psychoanalytic techniques. He concludes by commenting on future theoretical refinements and on the problems in the professional practice of this modality.     

Leadership Change and Organizational Regression

Psychotherapists have long recognized the therapeutic power of the here-and-now, but few have attempted to account for this power or provide a rationale for its efficacy. This leaves one of the most central concepts of group therapy without an adequate theoretical base. A major reason for this is the insufficiency of our Western assumptions of time and causality. These ascribe all human behaviors and cognitions to prior influences of one sort or another, making a true focus upon the present almost impossible. Even those who value the here-and-now are inevitably drawn into the past, because the Western philosophy underlying mainstream psychology makes this seem only logical. A theoretical revolution is therefore proposed that draws upon the lessons of history, the insights of other cultures, and developments in physics. This approach is then applied to group therapy, and specific advantages over conventional theorizing are noted.     

Oculomotor inhibition of return: Evidence against object-centered representation

ABSTRACT

Intermixing central, directional arrow targets with the peripheral targets typically used in the Posnerian spatial cueing paradigm offers a useful diagnostic for ascertaining the relative contributions of output and input processes to oculomotor inhibition of return (IOR). Here, we use this diagnostic to determine whether object-based oculomotor IOR comprises output and/or input processes. One of two placeholder objects in peripheral vision was cued, then both objects rotated smoothly either 90 or 180 degrees around the circumference of an imaginary circle. After this movement, a saccade was made to the location marked by a peripheral onset target or indicated by the central arrow. In our first three experiments, whereas there was evidence for IOR when measured by central arrow or peripheral onset targets at cued locations, there was little trace of IOR at the cued object. We thereafter precisely replicated the seminal experiment for object-based oculomotor IOR (Abrams, R. A., & Dobkin, R. S. (1994). Inhibition of return: Effects of attentional cuing on eye movement latencies. Journal of Experimental Psychology: Human Perception and Performance, 20(3), 467–477; Experiment 4) but again found little evidence of an object-based IOR effect. Finally, we ran a paradigm with only peripheral targets and with motion and stationary trials randomly intermixed. Here we again showed IOR at the cued location but not at the cued object. Together, the findings suggest that object-based representation of oculomotor IOR is much more tenuous than implied by the literature.     

Klinische und forensische Aspekte hypersexuellen Verhaltens

The present article deals with hypersexual behavior and experience which is characterized by excessive sexual activity and a high degree of psychological strain and/or endangerment for others. Initially, the historical developments of different conceptualizations of the construct which is currently predominantly denominated hypersexuality are illustrated from the beginning in terms of the famous case studies presented by Krafft-Ebing up to the current discussion about the inclusion of hypersexual disorder in the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5). Different diagnostical methods and approaches for hypersexual behavior are presented as well as a brief overview about the epidemiology and different etiological models and hypotheses. Finally, the forensic relevance of the construct for expert witness activity is discussed by focusing on the potential impact of hypersexual behavior on criminal responsibility and recidivism risk assessment.     

The effects of ignored versus foveated cues upon inhibition of return: An event-related potential study

Taylor and Klein (Journal of Experimental Psychology: Human Perception and Performance 26:1639–1656, 2000) discovered two mutually exclusive “flavors” of inhibition of return (IOR): When the oculomotor system is “actively suppressed,” IOR affects input processes (the perception/attention flavor), whereas when the oculomotor system is “engaged,” IOR affects output processes (the motor flavor). Studies of brain activity with ignored cues have typically reported that IOR reduces an early sensory event-related potential (ERP) component (i.e., the P1 component) of the brain’s response to the target. Since eye movements were discouraged in these experiments, the P1 reduction might be a reflection of the perception/attention flavor of IOR. If, instead of ignoring the cue, participants made a prosaccade to the cue (and then returned to fixation) before responding to the target, the motor flavor of IOR should then be generated. We compared these two conditions while monitoring eye position and recording ERPs to the targets. If the P1 modulation is related to the perceptual/attentional flavor of IOR, we hypothesized that it might be absent when the motoric flavor of IOR was generated by a prosaccade to the cue. Our results demonstrated that target-related P1 reductions and behavioral IOR were similar, and significant, in both conditions. However, P1 modulations were significantly correlated with behavioral IOR only when the oculomotor system was actively suppressed, suggesting that P1 modulations may only affect behaviorally exhibited IOR when the attentional/perceptual flavor of IOR is recruited.     

Sources of Variability in Sequelae of Very Low Birth Weight

Few investigations have examined the specificity of sequelae of very low birth weight (VLBW, <1500 g) or sources of variability in outcome. To better understand the nature and determinants of outcome, we assessed neuropsychological and achievement skills at mean age 11 years in 62 children with <750 g birth weight, 54 with 750-1499 g birth weight, and 66 term-born controls. Distinct cognitive constructs were identified by factor analysis, and the three birthweight groups were compared on these constructs and on composite measures of achievement. Although the group with <750 g birth weight performed less well on all tests than term-born controls, group differences in a perceptual planning factor and in mathematics remained even when IQ was controlled, and deficits were more pronounced in mathematics than in reading. Results from structural equation modeling were consistent with the hypothesis that neuropsychological skills mediated the relationship between birth weight and achievement. The findings confirm the differential deficit hypothesis, support the need to consider multiple sources of variability in VLBW outcomes, and highlight the importance of neuropsychological constructs in developing an explanatory framework.     

Predicting attention and avoidance: When do avoiders attend?

Three avoidance measures, the Miller Behavioural Style Scale (MBSS), Index of Self-Regulation of Emotion (ISE) and Mainz Coping Inventory (MCI), were compared in their ability to predict attention and avoidance of threats in the emotional Stroop task. It was also examined if the avoidance mechanism of individuals who would normally avoid threat-indicating words becomes disrupted under conditions of dopamine reduction. Results show that only the ISE predicted attention/avoidance of threat-indicating words. In addition, the avoidance mechanism, as measured by the ISE and MCI, was not activated when regular smokers abstained from smoking.
