Sexual Aspects of Rorschach Administration

The factor structure of the items of the 1962 16PF Form A was examined on a sample of 499 air traffic controllers. It was found that the test does indeed measure the primary factors it purports to measure although several of the factors found did not correspond well with the ideal pattern to be expected with the 16PF on this special, highly selected sample of American males. The results were not as discouraging to the 16PF user as would be indicated by other recent studies which shared certain methodological shortcomings.     

Centrality Preferences in Choices Among Similar Options

Three explanations were explored for the finding that people prefer the middle option rather than the extremes when choosing from an array of similar options. In Study 1, 68% chose the middle item from a set of three highlighters and three surveys, whereas 32% chose an item from either end, p < .0001. In Study 2, 71% selected the middle chair from a row of three chairs that were either all empty, or had a backpack occupying either one of the two end chairs, p < .0001. These results support a minimal mental effort principle rather than a preference for symmetry rule. In Study 3, 54.2% recalled more graphic items from the center poster of a 3-poster collage, whereas 31.3% and 14.5% recalled more items from the left and right posters, respectively, p < .004. These findings lend additional support to a focus of attention explanation.     

Testing four explanations for the better/worse-than-average effect: Single- and multi-item entities as comparison targets and referents

In six experiments, we tested four explanations for the better/worse-than-average effect (B/WTA) by manipulating the number of items comprising the target or referent of direct comparison. A single-item target tended to be rated more extremely than a single-item or a multi-item referent (Experiments 1–3). No B/WTA was obtained, however, when a multi-item target was compared with either a single- or multi-item referent (Experiments 4 and 5). A bias favoring a multi-item target was found only if cohesiveness among the items was increased through instructions (Experiment 6). The Unique-Attributes Hypothesis generally provided the best explanation the findings; the focalism explanation also demonstrated some empirical viability. The results suggest that important preferential decision-making outcomes can be affected by both the number of items and whether items are strategically manipulated to serve as targets or referents of comparison.     

Physiological effects of enriched environment exposure and LTP induction in the hippocampus in vivo do not transfer faithfully to in vitro slices

A number of experimental paradigms use in vitro brain slices to test for changes in synaptic transmission and plasticity following a behavioral manipulation. For example, a number of previous studies have reported a variety of effects of environmental enrichment (EE) exposure on field potential responses in hippocampal slices, but in no study was is it known what changes had been elicited in vivo. In the present study, we recorded from the hippocampus in vivo while rats underwent a brief period of EE. There was no detectable EE-induced change in synaptic efficacy in the dentate gyrus in vivo, but there was an increase in cellular excitability. In slices prepared from the same animals, we failed to observe any evidence of the excitability increase. We next tested whether LTP induction in vivo was better preserved in vitro. However, when slices from these rats were examined, there was no observable change in perforant path synaptic strength, although there was a modest increase in excitability that correlated with the increased excitability observed in vivo. These findings suggest that synaptic changes induced in vivo either are not preserved faithfully or are difficult to detect in hippocampal slices, while changes in cellular excitability are better preserved.Exposure to an enriched environment (EE) can improve performance on a variety of hippocampus-dependent memory tasks in both normal (Kempermann et al. 1997; Duffy et al. 2001; Teather et al. 2002; Schrijver et al. 2004; Irvine and Abraham 2005) and disease model (Ohlsson and Johansson 1995; Young et al. 1999; Jankowsky et al. 2005; Lazarov et al. 2005; Nithianantharajah and Hannan 2006; Laviola et al. 2008) animals. Previous studies attempting to understand the physiological changes that mediate these effects have yielded mixed results, which may in part be due to the variability in enrichment paradigms used in different laboratories, but which may also be due to the method used to measure hippocampal physiology.Traditionally, researchers have studied the effects of EE using ex vivo brain slices. Such studies have sometimes reported an increase in synaptic strength following enrichment (Green and Greenough 1986; Foster et al. 1996; Foster and Dumas 2001), but a lack of a change has also been observed (Duffy et al. 2001; Feng et al. 2001; Parsley et al. 2007). The ex vivo approach is predicated on the assumption that EE (or other behavioral) treatment induces changes in neural function that are of sufficient magnitude and extent that they will still be present when the brain is removed and studied in vitro. However, there could be many hidden effects of slice preparation (Kirov et al. 2004) that change or obscure effects occurring in vivo.In a previous study, we were surprised to find few effects of a 3-mo EE treatment on hippocampal synaptic function and plasticity when assessed in vitro (Eckert et al. 2010), despite our having observed with in vivo recordings substantial effects with shorter periods of EE exposure (Irvine and Abraham 2005; Irvine et al. 2006). We therefore considered the possibility that effects measured electrophysiologically in vivo may not be readily detectable in vitro. Testing this hypothesis requires studying the same animals in vivo and in vitro, a control procedure we are not aware of having been reported previously in the literature. In the present study, we examined whether the effects of EE or LTP induction in vivo could be detected in hippocampal slices taken from the same animals. We failed to detect any of the in vivo changes, except for a modest increase in cellular excitability following LTP.     

The cognitive and affective dimensions of moral conviction: implications for attitudinal and behavioral measures of interpersonal tolerance

The present studies investigate the role of both cognitive and affective dimensions of moral conviction in contributing to negative interpersonal responses. After demonstrating that the cognitive and affective dimensions of moral conviction are distinct constructs, the studies show that the cognitive dimension is sufficient to produce many forms of interpersonal intolerance. Simply believing an issue to be moral (i.e., objectively grounded, non-negotiable) results in greater intolerance for (Study 1), less sharing with (Study 2), and greater distancing from (Study 3) people with divergent attitudes. The emotional intensity with which beliefs are experienced is not alone explanatory. Nonetheless, it interacts with moral beliefs to produce the highest levels of interpersonal intolerance, distancing from dissimilar others, and context insensitivity. This interaction pattern between moral beliefs and affect was specific to emotional intensity and not other measures of attitude strength (Study 3).     

Daily Behavior Report Cards and Systematic Direct Observation: An Investigation of the Acceptability,Reported Training and Use,and Decision Reliability Among School Psychologists

More than ever, educators require assessment procedures and instrumentation that are technically adequate as well as efficient to guide data-based decision making. Thus, there is a need to understand perceptions of available tools, and the decisions made when using collected data, by the primary users of those data. In this paper, two studies that surveyed members of the National Association of School Psychologists with regard to two procedures useful in formative assessment, (i.e., Daily Behavior Report Cards; Systematic Direct Observation), are presented. Participants reported greater overall levels of training and use of Systematic Direct Observation than Daily Behavior Report Cards, yet both techniques were rated as equally acceptable for use in formative assessment. Furthermore, findings supported that school psychologists tend to make similar intervention decisions when presented with both types of data. Implications, limitations, and future directions are discussed.     

Effects of Performance Context on Processing Speed and Performance Ratings

The present study demonstrated that the presence of evaluatively polarized context performances not only produces contrast and halo effects on judgments of a target performance, but also causes judgments to be made much faster. Processing speed and positive halo were highly correlated, supporting the notion that halo in performance ratings results from raters' recall and use of a single, general impression. Furthermore, regression analyses demonstrated that processing speed mediates the relationship between context and halo. The relationship between these findings, halo, processing speed, and general impressions, as well as implications for performance appraisals, are discussed.     

Evaluation of Two New Scales Assessing Driving Anger: The Driving Anger Expression Inventory and the Driver's Angry Thoughts Questionnaire

This study assessed the validity of the Driving Anger Expression Inventory (DAX) and Driver's Angry Thoughts Questionnaire (DATQ). Scales within the DAX and DATQ appeared to assess separate, correlated constructs. Aggressive forms of thinking and anger expression correlated positively with each other, trait driving anger, aggressive and risky behavior, some crash-related conditions, general trait anger, and general forms of anger expression. Positive, constructive forms of thinking and anger expression correlated positively with each other, but minimally or negatively with other variables. Specific aggressive forms of thinking and anger expression formed stronger links with each other than other forms of expression, supporting the discriminant validity of the DATQ and DAX. Hierarchical regressions with DATQ and DAX scales entered after other variables showed that they added explained variance above and beyond other measures, supporting the discriminant and incremental validity of these scales. It was concluded that the DAX and DATQ have utility for researchers and clinicians interested in angry drivers.     

Die Effekte psychoanalytisch orientierter und verhaltenstherapeutischer Langzeittherapien

This prospective study compares 31 patients in behavior long-term-therapy (with an average of 63 sessions) with 31 patients in psychoanalytically-oriented long-term-therapy (with an average of 185 sessions) in a naturalistic design. All patients passed a diagnostic interview (SKID) by an external interviewer. Only patients with depression and anxiety problems (Axis I of DSM III – R) were included in the study. Symptoms (SCL-90-R), interpersonal problems (IIP-D) and goals (GAS) were examined at the beginning, after 1 year, after 2.5 and 3.5 years. We found that the characteristics of patients, who choose – or were referred to – psychoanalytically oriented or behaviour long term therapy were different, even when their diagnosis were comparable, in a number of characteristics, such as education, access to psychotherapy (recommended by professionals versus patients introduce themselves), the taking of psychotropic medication, and the strain of symptoms. The results demonstrate how research comparing therapies using parallelized samples do not meet reality in every case: Even if psychoanalists and behavior therapists do treat equal disorders, – and they each do that very successfully, as we could prove – the patients differ in many ways. Effect sizes and clinically significant results about changes of the symptomatic and of interpersonal problems are presented that prove the efficacy of the treatments.     

Algebraic Biology: Creating Invariant Binding Relations for Biochemical and Biological Categories

The desire to understand the mathematics of living systems is increasing. The widely held presupposition that the mathematics developed for modeling of physical systems as continuous functions can be extended to the discrete chemical reactions of genetic systems is viewed with skepticism. The skepticism is grounded in the issue of scientific invariance and the role of the International System of Units in representing the realities of the apodictic sciences. Various formal logics contribute to the theories of biochemistry and molecular biology and genetics. Various paths of extension are invoked in these formal logics in order to express the information of biological apodicticism. Symbolizing the appropriate notations for invariant relations and for biological extensions of relations is fundamental to the exact generating functions of discrete algebraic biology. Aspects of philosophical perspectives of the relation scientific number systems are contrasted. The deep distinction between physical motion and biological motion is expressed in terms the roles of Aristotelian causes. The interior motion within perplex numbers is contrasted with the exterior motion of physical systems. The need for a new mathematics for biology is suggested.
