Rorschach Variables and Big Five Scales as Predictors of Military Training Completion: A Replication Study of the Selection of Candidates to the Naval Special Forces in Norway

Thirty-nine undergraduate male college students drew five figures — an automobile, a clothed male, a clothed female, a nude male, a nude female — while a continuous record of their GSR activation was obtained. Analysis of GSR data showed that activation differed significantly from the relatively neutral but equally difficult drawing (i.e., the automobile). Nude figure drawings differed significantly in GSR activation from clothed figure drawings. GSR responses of largest amplitude showed significant shifts from the largest responses occurring to secondary sexual bodily areas in the clothed drawings to primary sexual areas in the nude drawings. Only the clothed male and the nude male drawings differed significantly between groups judged different in psychosexual adjustment.     

Postnatal handling induces long-term modifications in central beta-noradrenergic signalling in rats

Neonatal handling has been shown to induce a short-term reduction in the binding properties of beta-adrenoceptors and in their primary biochemical responses in the young rat brain, which may account for the reduced responsiveness to stress observed in the handled rats. We have studied the persistence and duration of these changes in cerebral cortex, cerebellum and hippocampus at successive stages of life in neonatally handled rats. Binding properties of the beta-adrenoceptors in handled animals were essentially similar to those of the control rats from 3 to 24 months of age. However, handling disturbed the efficacy of the beta-adrenoceptor intracellular signalling since the isoprenaline-induced accumulation of cyclic AMP was reduced in cerebral cortex at 1, 12 and 24 months; in cerebellum at 12 and 18 months; and in hippocampus at 3 and 12 months. This effect might be partially dependent on a regulatory action of handling on the adenylyl cyclase enzyme itself since both basal and forskolin-induced accumulation of cyclic AMP were persistently reduced. Therefore, postnatal handling can be considered as an effective intervention that modifies sensitivity to various hormonal and neurochemical signals; these changes may be involved over a long period of time in protection against an excessive response to stress. These results suggest that the long-lasting adaptation of the adenylyl cyclase transduction system, which affects the primary biochemical response of the beta-adrenoceptor, may participate in the effects of this manipulation.     

The knower and the known

This paper is a presentation and discussion of Spinoza's view on the knower, or the mind, as an agent. The knower is on his view to be regarded as an active or generative complex cognitive experience. Imagination, reason and intuition are the cognitive principles. On account of their intrinsic relation to the first law of nature, that of selfpreservation, together with the thesis of the mind as constituted by ideas or knowledge, these principles function at the same time as moral principles. Consequently, it makes sense to speak of an individual's moral attitude toward everything be knows. A discussion of imagination, reason and intuition mainly as cognitive principles is followed by some concluding remarks on the cognitive and moral relation between human beings: To know another human being is to know his knowledge. The moral attitude of individuals to each other is a function of their mutual knowledge of knowledge.     

Psychophysiologic chronometry: detection of facilitating and inhibiting processes in information processing using electroencephalographic and electromyographic data]

The objective of the present research was to tally the potential usefulness of psychophysiological measures in the systematic analysis of human information processing. Different context conditions were established in two cued choice-reaction time experiments. The context could either facilitate or inhibit the processing of an imperative stimulus. Event-related brain potentials (EEG-ERP) and event-related electromyograms (EMG-ERP) were recorded and from these biosignals latencies and duration times for different aspects of stimulus evaluation and movement execution were derived. The EEG-ERP provided measures for the time of primary stimulus categorization (N2), the time necessary to test actual stimulus information against stimulus expectancies (P3b), and the time necessary to check the decision about the stimulus-response mapping (pSW). From the EMG-ERP, processing times were derived which are related to the initiation of a motor program and to distinct sections of the movement trajectory. Results show that these latency measures react differently to different context manipulations. EEG-ERP measures, for example, reflected differences during stimulus evaluation which were not detectable in response- or EMG-derived movement times. The parallel analysis of EEG-ERPs and EMG-ERPs allowed delineation of processing modules which are responsible for particular context-dependent facilitation and inhibition effects. Moreover, the data revealed substantial overlap of evaluation times and movement times. This finding seems to be more compatible with a parallel processing model than with a strictly sequential model.     

Automatic change detection in vision: Adaptation,memory mismatch,or both? II: Oddball and adaptation effects on event-related potentials

In this study we compared the event-related potentials (ERPs) obtained in two different paradigms: a passive visual oddball paradigm and an adaptation paradigm. The aim of the study was to investigate the relation between the effects of activity decrease following an adaptor (stimulus-specific adaptation) and the effects of an infrequent stimulus within sequences of frequent ones. In Experiment 1, participants were presented with different line textures. The frequent (standard) and rare (deviant) texture elements differed in their orientation. In Experiment 2, windmill pattern stimuli were presented in which the number of vanes differentiated the deviant and standard stimuli. In Experiment 1 the ERP differences elicited between the oddball deviant and the standard were similar to the differences between the ERPs to the nonadapted and adapted stimuli in the adaptation paradigm. In both paradigms the differences appeared as a posterior negativity with the latency of 120–140 ms. This finding demonstrates that the representation of a sequential rule (successive presentation of the standard) and the violation of this rule are not necessary for deviancy effects to emerge. In Experiment 2 (windmill pattern), in the oddball paradigm the difference potentials appeared as a long-lasting negativity. In the adaptation condition, the later part of this negativity (after 200 ms) was absent. We identified the later part of the oddball difference potential as the genuine visual mismatch negativity—that is, an ERP correlate of sequence violations. The latencies of the difference potentials (deviant minus standard) and the endogenous components (P1 and N1) diverged; therefore, the adaptation of these particular ERP components cannot explain the deviancy effect. Accordingly, the sources contributing to the standard-versus-deviant modulations differed from those related to visual adaptation; that is, they generated distinct ERP components.     

Justice for the People? How Justice Sensitivity Can Foster and Impair Support for Populist Radical-Right Parties and Politicians in the United States and in Germany

Many people argue that support for populist radical-right political agents is motivated by people feeling “left behind” in globalized Western democracies. Empirical research supports this notion by showing that people who feel personally or collectively deprived are more likely to hold populist beliefs and anti-immigration attitudes. Our aim was to further investigate the psychological link between individuals' justice concerns and their preferences for populist radical-right political agents. We focused on stable individual differences in self-oriented and other-oriented justice concerns and argue that these should have opposing correlations with preferences for populist radical-right parties. We tested our hypotheses in two national samples, one from the United States (N = 1500) and one from Germany (N = 848). Sensitivity to injustice towards oneself enhanced the likelihood of preferring Trump (United States) and Alternative für Deutschland (AfD) (Germany) via increased anti-immigration attitudes and increased populist attitudes. Sensitivity to injustice towards others reduced the likelihood of preferring Trump and AfD via decreased anti-immigration attitudes. We discuss our findings in regard to how stable individual differences in the evaluation of fairness can motivate intra- and interpersonal political conflicts in modern w estern societies and how politics and mass media can fuel these conflicts.     

The Psychological Basis of Homophobia: Cultural Construction of a Barrier

The main goals of this article are: (a) to analyze the intricate relations between sexuality, gender, culture and power, and more precisely, the connections between homophobia and sexism; and (b) to analyze the psychological and cultural basis of homophobia and its affective roots. The model of the semiotic regulatory system and the general notion of tension between the two processes (specified by Ernest Boesch)--Heimweh ("homeward road"--striving towards the known and the secure) and the Fernweh ("road to the far away"--adventure, encountering novelty) is used as the theoretical ways to analyze homophobia as a cultural barrier. It is suggested: homophobia is a boundary phenomenon of affective meaning making, a collective historical-cultural construction. Presented in the conclusion are some implications of the promotion of strategies against homophobia in our societies.     

The Paranoid Style in American Politics Revisited: An Ideological Asymmetry in Conspiratorial Thinking

It is often claimed that conspiracy theories are endorsed with the same level of intensity across the left-right ideological spectrum. But do liberals and conservatives in the United States embrace conspiratorial thinking to an equivalent degree? There are important historical, philosophical, and scientific reasons dating back to Richard Hofstadter's book The Paranoid Style in American Politics to doubt this claim. In four large studies of U.S. adults (total N = 5049)—including national samples—we investigated the relationship between political ideology, measured in both symbolic and operational terms, and conspiratorial thinking in general. Results reveal that conservatives in the United States were not only more likely than liberals to endorse specific conspiracy theories, but they were also more likely to espouse conspiratorial worldviews in general (r = .27, 95% CI: .24, .30). Importantly, extreme conservatives were significantly more likely to engage in conspiratorial thinking than extreme liberals (Hedges' g = .77, SE = .07, p < .001). The relationship between ideology and conspiratorial thinking was mediated by a strong distrust of officialdom and paranoid ideation, both of which were higher among conservatives, consistent with Hofstadter's account of the paranoid style in American politics.     

The two landscapes of northern Norway

Our concepts of the world come from our common activities in the world. Without coastal fishing, or seafaring, in boats too large for their crews to draw them ashore, there is no place for the concept of a harbour. And without reindeer herding, there will be no concept of JASSA. That is one point. The other is this: without some of the coastal fisherman's skill and local knowledge, you will not be able to recognize a natural harbour when you see one. And without the reindeer herder's skill, you will not be able to recognize a JASSA when you see one. To put it all rather bluntly. Though there is more of both work and experience behind the first part of this article, about the world of coastal fishing, most of my academic friends have found the latter part, about the concept JASSA, the better and more readable. Can it be that the better teacher is the one who has just learnt the lesson himself?     

Ipsilesional Arm Motor Sequence Performance After Right and Left Hemisphere Damage

Aiming movements are part of daily activities but the brain hemispheres’ role in targeted aiming sequential movements is not fully clear. Start and execution of discrete and sequential tasks toward targets were analyzed in 10 individuals with left-hemisphere damage, 10 right-hemisphere–damaged, and 10 healthy ones. Arm movements were performed over a digitizing tablet, following stimuli on a monitor, from initial position toward right and left-positioned targets. Poststroke individuals used their ipsilesional arm and healthy individuals, both arms. Right-hemisphere–damaged individuals showed higher reaction time and left-hemisphere–damaged individuals, lower smoothness. Due to spatial demand of tasks, the right hemisphere played a major role in movement planning, while the left, in movement execution.
