Brain fingerprinting classification concealed information test detects US Navy military medical information with P300.

A classification concealed information test (CIT) used the "brain fingerprinting" method of applying P300 event-related potential (ERP) in detecting information that is (1) acquired in real life and (2) unique to US Navy experts in military medicine. Military medicine experts and non-experts were asked to push buttons in response to three types of text stimuli. Targets contain known information relevant to military medicine, are identified to subjects as relevant, and require pushing one button.

Sex differences in verbal and visual-spatial tasks under different hemispheric visual-field presentation conditions.

This paper reports sex differences in cognitive task performance that emerged when 39 Australian university undergraduates (19 men, 20 women) were asked to solve verbal (lexical) and visual-spatial cognitive matching tasks which varied in difficulty and visual field of presentation. Sex significantly interacted with task type, task difficulty, laterality, and changes in performance across trials. The results revealed that the significant individual-differences' variable of sex does not always emerge as a significant main effect, but instead in terms of significant interactions with other variables manipulated experimentally.

The concealed information test as an instrument of applied differential psychophysiology: methodological considerations.

In this interpretative paper, I consider four sets of methodological issues that may be relevant to improving the concealed information test (CIT) as an instrument of applied differential psychophysiology. The first set has to do with psychophysiological measurement in the CIT (e.g.

Sexually dimorphic effects of acute nicotine administration on arousal and visual-spatial ability in non-smoking human volunteers.

The effect of an acute administration of nicotine on arousal and visual-spatial ability in healthy non-smoking participants was investigated. Healthy adult volunteers with a mean age of 19.98 years received a transdermal nicotine or placebo patch prior to completing a water-level task and two mental rotation tasks while concurrent psychophysiological recordings were taken.

P300-based detection of concealed autobiographical versus incidentally acquired information in target and non-target paradigms.

The basic rationale of P300-based tests of concealed information compares responses to critical ('probe') and non-critical ('irrelevant') items. Accuracy, both in the laboratory and the field, is the degree to which responding to probes exceeds that to irrelevants. The present laboratory study assessed the influence of two factors on accuracy.

Pavlovian George Windholz (1931-2002): an exemplar of scholarly "observation and observation" and a critical contributor to psychology, and hence to behavioral neuroscience.

Although most members of the Pavlovian Society properly focus their efforts on empirical research, the scholarly, critical conceptual contributions of some individuals are also relevant to progress in psychology and behavioral neuroscience. This paper discusses the contributions of the late George Windholz (often in collaboration with Peter Lamal) as: (a) a historian of Pavlov's life and work; (b) an analyst of priority issues in psychology as a science; (c) a refuter of myths perpetrated by psychology texts. These contributions provide an example of the scholarly form of the motto "observation and observation," where the data used to test hypotheses comprise original documents (often in languages other than English) examined by the historian's critical eye.

Pavlov's methodological behaviorism as a pre-Socratic contribution of the melding of the differential and experimental psychology.

The differential/experimental distinction that Cronbach specified is important because any adequate account of psychological phenomena requires the recognition of the validity of both approaches, and a meaningful melding of the two. This paper suggests that Pavlov's work in psychology, based on earlier traditions of inquiry that can be traced back to the pre-Socratics, provides a potential way of achieving this melding, although such features as systematic rather than anecdotal methods of observation need to be added. Pavlov's methodological behaviorist approach is contrasted with metaphysical behaviorism (as exemplified explicitly in Watson and Skinner, and implicitly in the computer-metaphorical, information-processing explanations employed by current "cognitive" psychology).

Roots of the Pavlovian Society's missions of the past and present: the Pavlov dimension.

This paper offers an interpretation of the relation between Pavlov's life and work and the missions of the Pavlovian Society, both past ("observation and observation") and present ("interdisciplinary research on the integrated organism"). I begin with an account of Pavlov's life and his influence on contemporary thought. I then indicate the relation of some of Pavlov's attitudes (e.
