Information leakage in the Response Time‐Based Concealed Information Test

The Response Time‐Based Concealed Information Test (RT‐CIT) can reveal when a person recognizes a relevant (probe) item among other, irrelevant items, based on comparatively slow responses to the probe item. For example, if a person is concealing his or her true identity, one can use the suspected identity details as probes, and other, random details as irrelevants. However, in our study, we show that even when participants are merely informed about such probes (i.e., the relevant identity details) before performing the RT‐CIT, their responses will also be slower to these details. Hence, it is more difficult to distinguish such innocent but pre‐informed persons from actually guilty persons. At the same time, we introduce a CIT version with familiarity‐related inducer stimuli, but with no targets, that elicits probe‐minus‐irrelevant RT differences only among guilty participants but not among informed innocent participants. Implications for the theory and the application of CITs are discussed.     

After images and pain tolerance: a descriptive study on their interrelationship

After images are based on physiological processes, they can also be treated as subjective phenomena with a psychological meaning. This statement also applies to pain. The basic working hypothesis of this study concerned the relationship between the two phenomena. Forty-one respondents (23 females, 18 males, age range 20-45 years) were given the Cold Pressor Test and the Serial After Image Technique. The data analysis was done by means of cross-tables and an exploratory optimal scaling program (OVERALS). Three pain tolerance groups (low, medium, high) could be differentiated fairly well on the basis of the after image characteristics of the respondents. Pain intolerant respondents more frequently had small and "immature" after images, whereas highly pain tolerant respondents had more large and "mature" after images. The implications of these results for a bio-psycho-social theoretical frame of reference for pain are discussed.     

Autobiographical memory specificity, psychopathology, depressed mood and the use of the Autobiographical Memory Test: a meta-analysis

Reviewing the literature on autobiographical memory overgenerality, as measured by a cueing task like the Autobiographical Memory Test (AMT), gives a diffuse view of the moderating role of depression. This meta-analysis is an attempt to investigate the role of depression in the specificity of autobiographical memory, while accounting for the role of patient and task variables as possible moderators. Meta-analytic techniques are used to synthesize data from 14 studies on the recall of specific autobiographical memories in psychiatric and non-psychiatric samples. The results confirm the relationship between overgenerality and depression. The psychiatric patients are less specific than their non-clinical controls. It is not possible to establish that this result is solely due to a (co-morbid) diagnosis of depression. Self-reported depressed mood is also related to an impairment of autobiographical memory specificity. The way of presenting cues, audio taping responses and the maximum available amount of time to respond, are moderators of AMT performance.     

Further exploration memory bias in compulsive washers

The aim of the present study was to replicate Radomsky and Rachman's findings on memory bias in obsessive-compulsive disorder (OCD), using the same procedure but an increased sample size, more specific control groups, and a full analysis of contamination attribution data. Sixteen OCD-washers, 16 OCD-checkers, 16 social phobic patients and 16 non-anxious controls were presented with 50 'clean' or 'dirty' objects. After this incidental encoding phase, participants were asked to freely recall the objects, to rate their anxiety when almost touching each object, and, finally, to attribute each object to one of the two contamination conditions ('clean' or 'dirty'). Verbal episodic memory was also assessed with the California Verbal Learning Test. The results indicate that, contrary to Radomsky and Rachman's findings, OCD-washers did not differ from the other participants in their memory for 'clean' and 'dirty' objects. However, the OCD-washers recalled more accurately the 'dirty' source of contamination than the 'clean' source. This result was specific to the OCD-washers, and suggests a memory bias for contextually threatening information. The differences between our findings and those published by Radomsky and Rachman's are discussed.     

Effects of psychological defense on processing of neutral stimuli indicated by event-related potentials (ERPs)

The Defense Mechanism Test (DMT) is claimed to identify personnel with a high risk for accidents. A new explanation for why the DMT seems to predict performance when survival depends on split second decisions is proposed. Sixteen right-handed, adult male students were tested with the DMT and with an ERP paradigm (two sine wave tones, presented binaurally). Each subject was tested with a one-stimulus paradigm, and a passive and an active oddball paradigm. Under the passive oddball condition, High defensive subjects differed from Low, having significantly smaller N2 amplitudes (low immediate perception), and significantly larger P3 amplitudes (rely on later associative mechanisms). High defensive subjects seem to have less ability to perceive the environment correctly immediately. This slowness may be fatal when life depends on split second decisions. The fundamental neurophysiological difference may also be the basis for the very complex cognitive and perceptual mechanisms involved in psychological defense mechanisms.

Age differences in cognitive performance: A study of cultural differences in Historical Context

Ethnicity and cultural experience can affect neuropsychological performance, but they are rarely assessed in historical context. Attention measures are considered strongly biologically determined and therefore potentially culture‐fair. In this study, we assessed the cross‐cultural equivalence of Spanish and English versions of the Trail Making Test (TMT; Reitan, 1958, Perceptual and Motor Skills, 8, 271–276) and the Brief Test of Attention (BTA; Schretlen et al., 1996, The Clinical Neuropsychologist, 10, 80–89) in two large samples of Americans (N = 203) and Spaniards (N = 213), divided into younger and older subgroups. The older Spaniards lived under Franco's political regime (1936–1975), whereas the Americans never experienced such repression. Overall, TMT performance was culture‐sensitive, whereas BTA performance was not. However, when both groups were stratified by age, cultural differences in TMT performance were restricted to older participants, suggesting that historical experience across generations might have contributed to the observed differences in cognitive performance. Even such basic cognitive processes as attention, working memory, and resource sharing might be shaped to some degree by historical experiences that contribute to cultural differences.     

Test–retest reliability and task order effects of emotional cognitive tests in healthy subjects

Little is known of the retest reliability of emotional cognitive tasks or the impact of using different tasks employing similar emotional stimuli within a battery. We investigated this in healthy subjects. We found improved overall performance in an emotional attentional blink task (EABT) with repeat testing at one hour and one week compared to baseline, but the impact of an emotional stimulus on performance was unchanged. Similarly, performance on a facial expression recognition task (FERT) was better one week after a baseline test, though the relative effect of specific emotions was unaltered. There was no effect of repeat testing on an emotional word categorising, recall and recognition task. We found no difference in performance in the FERT and EABT irrespective of task order. We concluded that it is possible to use emotional cognitive tasks in longitudinal studies and combine tasks using emotional facial stimuli in a single battery.     

Cross-cultural differences in processes underlying sequential cognitive activity

Abstract: Similarities and differences in the processes underlying performance on the Stroop Color-Word Test (Card A, 100 color words/black ink; Card B, 100 color patches; Card C, 100 color words/incongruous ink color) were investigated with Japanese ( N = 96) and Americans ( N = 96) with stimulus items read: (a) vertically, top to bottom; and (b) horizontally, left to right. Total time as well as errors, namely, those involved with the underlying processes of identification and sequential organization, were significantly longer or more frequent on Card C than on Cards A and B for both nationalities and spatial arrangements. Further, greater frequency of serial organization errors in females than in males was obtained for the Japanese group, and the opposite for the American group. The implications and directions for future research are discussed.
